United States Patent O 3,286,664 HLUP-PROOF BOOTH' Ira A. Folks, 5430 Sinclair Road, Columbus, Ohio Filed Mar. 16, 1966, Ser. No. 534,698 9 Claims. (Cl. 1097) This is a continuation-impart of application Serial No. 336,996, tiled January l0, 1964, now, abandoned, the disclosure of which is incorporated herein.y

This invention relates to improvements in holdup proof devices, and more particularlyhas reference to novel improvements in a holdup or burglar proof booth and the like through which access may be had only by authorized` persons to a room, security area or the like, whichV is protected by the said booth.

Devices of the general type are known in the prior art; however it has always been a problem to make a devicey of such complexity and dependability as to prevent operators from disclosing to unauthorized persons the secret orA combination of how to gain access to an area secured by` such holdup proof devices, whether such combination be, given away by dishonest operators or by an honest operator under compulsion. The present invention is an improvement over my U.S. Patent No. 1,989,591, issued January 29, 1935, and comprises a newl master mechanical mechanism and plural linkage means for more eliectively actuating revolving mechanisms in response to characteristics of the operator to be hereinafter described. The present invention provides not only more effective operating mechanisms but additional safeguards over those provided by my prior patent, referred to above, the disclosure and drawings of which are expressly incorporated herein.

It is an object of this inventiony to provide a burglar proof device having at leastv two interdependent locking means for an enclosure which will automatically prevent opening of the enclosure and will lock both parties in when more than onev person enters and attempts to operate the device.

A further object of this invention is4 tos provide a burglar proof device and an energized circuit and alarm system for an enclosure of the class described, which does notdepend for its operation on tumbler and pin combination means conventionally known to locksmiths.

A still further object of this invention is to provide a burglar proof locking apparatus which depends for its operative combination on non-verbal characteristics.

It is a still further object of this invention to provide a burglar proof locking apparatus which depends for its operative combination upon physical characteristics of the operator.

It is a further object of this invention to provide a burglar proof device which depends for its operation upon the ability of the operator to remember and to recognize photographs or other pictorial representations which are difficult or impossible to describe with sutiicient clarity to permit a third party to substitute himself for the operator.

Further objects of this invention and advantages will be apparent to those skilled in the art from the following specication relating to the drawings annexed hereto:

Reference is now made to FIGURES 1 and 2, in particular for a general description of the function of the holdup-proof booth. As best shown in FIGURE 2, the booth comprises an enclosed area having an entrance door 20, an exit door 40, walls 60and 80 and a floor 100. The booth also has a ceiling of conventional structure not s hown. The door 20 comprises

panels

22 and 2,4 which are held in upright parallel position by

upright members

26 and 26. The door is also provided with an operating arm 28, the function of which will be described hereinafter. Door 20 may be provided with

handles

30 and 32 for opening and closing the door. Upright 26 of door 20 may also be provided with a slot 34, as best shown in FIGURES 1 and 4, and a supporting member 36 across the bottom to which operating arm 28 is connected, as best shown in FIGURE 4. The purpose of slot 34 will be described hereinafter. Entrance door 20 is pivotally connected by hinge 38 to corner member 56.

The holdup-proof booth is also provided with an exit door 40 comprising

panels

42 and 44 held in parallel upright position by

supports

46 and 46 as best shown in FIGURE 2. Door 40 may be provided with a handle 48 on the inside and with a knob S0 on the outside for operating bolt 52 to open the door, in a manner to be described hereinafter. The exit door 40 is pivotally connected by means of hinge 54 to corner member 56.

Panels

22 and 42 may, in the preferred embodiment, be slidably mounted for vertical movement in a manner to be described hereinafter.

Wall 60 comprises an inner panel 62 and an outer panel 64. Included within wall 60 is an operating 4shaft 66 rotatably mounted in

supports

68 and 68 having secured at a first end thereof a cam 70 and at a second end a cam 72, the latter cam being best shown in FIGURE 4. An operatinglever 74 is secured to shaft 66 for pivotally moving -cams 70 and 72. Cam 72 is pivotally connected to rod 76 and rod 76 is slidably secured by a keeper 78. It will be apparent from FIGURE 4 that cam 72 may selectively lock door 20 in a manner to be described hereinafter. The function of operating7 rod 76 will be described in connection with the operation of the oor 100. The operation of cam 70 will be described hereinafter.

Wall 80 comprises an inner panel 82, an intermediate panel 84 and an outer panel 86. Outer panel 86 and intermediate panel 84 are held in vertical parallel relationship by

upper members

85 and 85 and form a door which pivots by means of hinge 87 and is locked 'by means of a lock shown generally at 88. The access door formed by

panels

84 and 86 and locked by lock 88 is provided for access into the master locking mechanism chamber. The operation of lock 88 will be described hereinafter. The master lock mechanism is mounted on the back side of wall 80. The operating controls mounted on the frontA of panel 80 include hand lock 700, window 90 through which may be viewed a picture 382, the light switch 92 which turns on light 94, crank 236, knob 410 for operat-k ing'a picture wheel as will be described hereinafter, and a pusher 420. In addition, on corner section 96 there s a bolt crank 480, which will be described later.

In the preferred embodiment some or all of

panels

22, 24, 42, 44, 62, 64, 82, 84, and 86 are made of a bullet proof material.

FIGURE 3 shows the bottom side of floor 100 including elements 102a, b, c, and d, attached to the bottom side thereof. Floor 100 rests by means of elements 102 upon crossbars 106 which, in turn, are supported at the corners by braces 108. Secured at the intersection of crossbars 106 is a member 110 having downwardly extending projections 112 and crossbar 114 which rest's against crossbeam 120. Crossbeam 120 has extending elements 120a and 120b which are pivoted by

bearings

122 and 122. `Crossbeam 120e` is attached at a pivot point 124 while member 120d of crossbeam 120 has aixed at the end thereof a locking plate 12,6. Thus it will be seen that when weight is applied to floor 100 a force is exerted by means of elements 102 downwardly upon crossbars 106 and through member 110 and bar 114 -to crossbeam 120 thereby tending to cause beam 120 to pivot on elements 120a and b in bearings 122. Element 120e` tends to move downwardly while element 120d tends to move upwardly. Crossbars 106 are preferably made of a semirigid material which is flexible enough to exert a force downwardly at the center of element 110; however, crossbeam 120 is preferably constructed of a heavy rigid material whereby it is possible by xing the end of element d to prevent elements 120C and 120d from pivoting about elements 120a and 120]: in bearings 122.

Referring now, in particular, to FIGURE 4, it will be seen that lever 130, which is pivotally connected at 132 to rod 76 and pivotally mounted at fulcrum 134, is in the position shown in FIGURE 4 and locking plate 126 is free to move upwardly. However, when operating handle 74 is moved upwardly causing shaft 66 to rotate thereby moving cam 72 in an upward direction, rod 76 will cause lever to pivot at 134 Vthereby xing locking plate 126 in the position shown. It will be seen then that when handle 74 is in the upward position, that is when cam 72 does not engage door 20 at slot 34, a weight on floor 100 will be ineffective 4to cause crossbeam 120 to pivot.

In addition to the operation of lever 130 which, in effect, may lock oor 100 in a fixed position, floor 100 may be locked in a xed position 'by means of rod 140 having a curved end 142, as best shown in FIGURE 3. Rod is slidably received by

members

144 and 144 and is biased toward locking plate 126 by means of spring 146 which is secured by keeper 148. Rod 140 is caused to disengage locking plate 126 by operating arm 28 which is attached to door 20. It will be seen, then, that when door 20 is fully closed, as shown in FIGURES 3 and 4, rod 140 does not engage locking plate 126; therefore, beam 120 is free to rotate about elements 120a and 120b in bearings 122. If, however, door 20 is even partially open, even a half an inch, rod 142 will engage locking plate 126 thereby preventing any pivotal motion of crossbeam 120. It will thus be seen that, rst, unless door 20 is fully closed, and secondly, door 20 is locked by means of 4cam 72, force exerted by the weight of an operator on floor 100 will Ibe ineffective to cause pivotal movement of crossbeam 120.

Referring now to FIGURE 5, which shows the master lock mechanism from the rear, as would be viewed through the master lock mechanism access door. The predominating element of the master lock mechanism is a master lever 200 which is pivotally mounted upon pin 202. The basic concept of the master lock mechanism is thatl the master lever 200 must be permitted to pivot about pin 202 before the exit door 40 can be open. If, however, master lever 200 pivots excessively about pin 202 both the entrance door 20 and the exit door 40 are caused to be locked, in a manner to be described hereinafter, thereby confining the person within the booth until another person secures his release from the outside. Thus, it is possible, not only to prevent entry into a vault or other secured area but to confine a person who attempts to enter the secured area without authority.

Referring again to FIGURE 5, master lever 200 is biased to the left, as viewed in FIGURE 5, by means of spring 204. Master lever 200 is slidably mounted in guide 206 as better shown in FIGURE 8. Master lever 200 is xed in the position shown in FIGURE 5 by a toggle formed of elements 220 and 222 pivotally connected at 224. Member 220 is pivotally connected by means of pin 226 to panel 82 while member 222 is pivotally connected to master lever 200 by means of pin 228. Member 222 is biased in a downward position by means of spring 230 which is attached to pin 202. Pivotal movement of master lever 200 in response to bias spring 204 is permitted when pusher cam 232 is operated by means of pin 234 and crank 236, the latter being best shown in FIGURE 1. When crank 236 is operated, pusher cam 232 bears against the pivotal point 224 permitting toggle elements 220 and 222 to pivot about point 224 as master lever 200 pivots in a counterclockwise direction as viewed in FIGURE 5.

Lever 200 is further biased by a stop or check 240, of the type commonly used for closing doors, for producing a smoother operation. Stop 240 is connected at one end by a pin 242 and the piston rod 244 is operably connected to master lever 200 through rod 246 which, in turn, is, pivotally connected to master lever -200 at pin 248.

5. Master lever 200` is pivotallyV and slidably connected to lever 260' by means of pin 262. Lever 260 is, in turn, pivotally connected to cam 70 by means of pin 264. The slidable connection between master lever 200 and lever 260 permits cam 70 to rotate as lever 74 is moved causing shaft 66, on which cam 70 is mounted, to rotate while the master lever 200 is in the locked position as shown in FIG- URE 5. When master lever 200 is permitted to pivot about pin 202 in response to bias spring 204, the lower end of master lever 200 is permitted to move by the slidable connection with lever 260. After master lever 200 has been permitted to pivot about pin 202, as will be described hereinafter, it may be returned t the position shown in FIGURE by the action of lever 2.60 as cam 270 rotates in response to movement of lever 74, as best shown in` FIGURES 1 and 2. Thus, a clockwise rotation of cam 70, as shown in FIGURE 5, causes lever 260 to move to the left engaging pin 262 thereby causing master lever 200 to pivot clockwise to the position shown in FIGURE 5.

If, however, excessive weight, for example the weight of more than one person, is applied to floor 100, as shown in FIGURES 1 and 4, operation of lever 74 to cause a clockwise rotation of cam 70 is prevented in the manner now to be described. As described previously, crossbeam 120 is pivotally connected at the end of member 120C by connection 124, as best shown in FIGURE 3 and FIG- URE 5. Iffloor 100 is freed for downward movement causing beam 120 to pivot with a downward motion on connection 124, rod 270 which is adjustably connected to rod 274 by linkage means 272, is caused to move downwardly. Rod 270 is guided by bracket 276i. Downward motion of rod 270 and rod 274 operates a scale mechanism comprising a lever 280 having an upstanding portion 282, rod 284, and bias spring 286. Lever 280 is engaged by keeper 288 and pivotally connected at pin 290 to panel 82. The upstanding portion 282 of lever 280 is pivotally connected to lever 284 by pin 292. The upper end of bias spring 282 is secured by means of hook 294 to a bracket 296 which is fixed to panel 82. The lower end of bias spring 286 is pivotally secured to lever 280 by means of pin and clevis 298. Lever 280 carries index 300 which cooperates withV indicia 302 on panel 82 to permit reproducible adjustment of the sensitivity of the scale mechanism. Adjustment of the scale mechanism is made by linkage 272 and by wing nut 297 to limit the amount of weight which may be upon the floor 100 and yet permit operation of cam 70 by means of lever 74. After proper adjustment, if excessive weight is applied to floor 100, as by the entrance of two persons, lever 280 will be caused to be moved downwardly beyond the adjusted point thereby causing rod 284, which is slidably engaged by keeper 304, to contact catch 310 which is pivotally mounted by pin 312 and biased by means of spring 314 through hook 316. Excessive motion to the right, as viewed in FIGURE 5, of rod 284 as the result of excessive weight of floor 100, causes catch 310 to engage teeth 318 on cam 70 thereby preventing clockwise rotation of cam 70. It will be apparent then, that if cam 70 is locked in the position shown in' FIGURE 5, cam 72 which is mounted on the opposite end of shaft 66 engages door by slot 34 thereby lockingthe entrance door preventing the persons from exiting through the entrance door by which they entered. Thus, if two persons attempt to enter the Vault they are captured within the holdup-proof booth.

An unauthorized person may also be captured in the booth if the measurements of his hand do not conform to the dimensions of the hand of the person authorized to enter the vault through the booth as will now be described. Rod 330 is pivotally connected near the lower end of master lever 200 by means of pin 332. Rod 330 is further pivotally connected to lever 336 by means of pin 338 and is slidably engaged in bracket 340. Lever 336 is pivotally connected by means of pin 342 to rod 344 which is in turn pivotally connected by means of pin 346 to cam 350. Cam 350 pivots about a pin 352and operates in a manner to be described hereinafter. Lever 336 is also pivotally connected by means of pin 360 to rod 362 which is slidably held by keeper 364. At its lower end lever 336 is slidably engaged by slide lock member 702 of lock 700 which will be described hereinafter. Briey, slide lock member 702 is selectively freed for movement in response to the position of slide lock keys 704. Slide lock keys are in position to permit free slidable motion of slide lock member 702 only when the measurements of the operator-s hand conform to preselected dimensions. If slide lock member 702 is freed for movement when the toggle formed by elements 220 and 222 is broken by operation of the cam pusher 232 and master lever 200 pivots about pin 202 in a counterclockwise movement, lever 336 causes slide lock member 702 to move to the right, as viewed in FIGURE 5, thereby permitting lever 336 to pivot about pin 360 causing cam 350 to rotate in a clockwise direction. If the master lever 200 is not permitted excessive movement, as will be described hereinafter, the operation just described will permit the entrance door to be unlocked, in a manner to be described hereinafter and will not lock the entrance door. If, however, slide lock member 702 is not free to move then lever 336 is caused to pivot about its engagement with slide lock member 702 thus causing excessive movement of lever 344 and consequently excessive clockwise rotation of cam 350 thereby locking the exit door in a manner to be described hereinafter and also causing rod 362 to move to the right, as viewed in FIGURE 5, pushing pivotal lever 366, which is pivoted about a pin 368, against catch 310 causing catch 310 to engage teeth 318 thereby locking the entrance door in the manner previously described. It will be apparent, then, that if more than one person attempts to enter the vault or if a person whose hand measurements do not conform to the preset dimensions attempts to enter the vault, then the entrance door will be locked in the manner just described.

The operation of hand lock 700, shown in FIGURE 7, will now be described. The central operating member of lock 700 is slide lock member 702, shown in FIGURES 5, 6, 7 and 7A. Slide lock member 702 is provided in an upper horizontal portion with a slot for slidable connection with lever 336, as shown in FIGURES 5 and 6, and in a lower vertical portion with a plurality of key slots 703 as best shown in FIGURES 5 and 7A. Slide lock member 702 may be selectively released for slidable movement for locked in position according to the positions of slide lock keys 704 as best shown in FIGURES 7 and 7A. Lock engaging keys 704 have downwardly extending projections 705 which engage slots 703 of the slide lock member 702. Portions of the downwardly extending projections 705 are notched at selected points thereby permitting slide lock member 702 to move freely when all the notches in downward extensions 705 are aligned with slide lock member 702. It will thus be seen that if even one of the notched portions of downward extension 705 on lock key 704 is improperly placed, slide lock member 702 will be locked in a iixed position. Lock keys 704 are adjustably connected to operating

rods

706, 708, 710, 712, 714, 716, 718, 720 and 722 by means of nuts 724. Operating rods 706 through 722 are biased by means of springs 730 to maintain lock 700 in the locked position, that is xing slide lock member 702, at all times except when an authorized person having hand measurements which conform to the preset dimension of hand lock 700. Spring members 730 bias the operating rods 708 through 720 between flanges 734 and operating

rods

706 and 722 between flanges 736 and brackets 738. In operation, hook 740 engages the operators thumb and serves as a stop. Upstanding rod 746 engages the operators hand between the thumb and forefinger, causing rod 708 to move lock engaging member 704 rearwardly from the partition 732. Yoke members 748 engage the three center fingers of the operators hand and through

rods

710, 714 and 718 cause lock engaging member 704 to move rearwardly away from partition 732. Upstanding rods 752 engage the operators hand between the respective fingers and through operating

rods

712, 716 and 720 cause lock engaging members 704 to move rearwardly away from the partition 732. Hook 750 engages the operators little finger and serves as a stop. Lever 756 is pivoted at p-in 758 and pivotally connected to rod 722. Lever 756 engages the operators hand and, through rod 722, causes lock engaging member 704 to move toward the partition 732. Pedal 760 is depressed by the palm of the operators hand causing shaft 762, which is pivotally mounted in bracket 764, to rotate pivot bracket 766 thereby operating rod 768 and pivot member 770. Thus it will be seen that when pedal 760 is depressed by the operators hand lock engaging member 704 is moved toward the partition 732 through pivotal shaft 762, rods 768 and 7 06.

As will be seen from the above description of hand lock mechanism 700, the slide lock member 702 will be free to move only when the measurements of the operators hand conform to the present dimensions of the hand lock mechanism so that the notches in downward extensions 705 of slide lock keys 704 are all positioned to permit free slidable motion of slide lock member 702. The hand lock mechanism 700 is in all essential respects identical to the hand lock mechanism described in my prior patent particularly in FIGURES 8, 10 and l1. The drawings and description of the hand lock mechanism of my prior patent are expressly incorporated herein by reference.

I now return to the description of other features of the master lock mechanisms, making particular reference to FIGURES 5, 9 and 9A. Located behind wall 80 and window 90 as shown in FIGURE l, is a picture profile lock including a picture wheel 380, as best shown in FIGURE 5, having on the side adjacent panel 82 a plurality of pictures 382. Wheel 380 has a plurality of threaded orices 384 on the side distant from panel 82. A screw or bolt member 386 may be threadably secured into any selected threaded orifice 384. In addition, wheel 380 has a plurality of pins 388 extending therefrom. Picture wheel 380 is rotatably mounted by means of pin 390 on swinging lever 392 which is, in turn, pivotally mounted to panel 82 by means of pin 394. Swinging lever 392 contacts lever 398 at a point 396. Lever 398 is pivotally mounted by a pin 400 to panel 82 and is received by keeper 402. As best shown in FIGURES 9 and 9A, lever 398 is biased toward wall 80 by a spring 406 which is maintained in position by pin 404 and keeper 408. Lever 398 is maintained a distance away from panel 82 by an enlarged portion 414 on rod 412 of pusher It will be noted from FIGURE that wheel 380 and lever 392 would tend to pivot on pin 394 to the left as viewed in FIGURE 5 if it were not that lever 398 held lever34 in the position shown. It will be seen that if pusher rod 410 is operated, that is pushed toward wall 80, per 398 will move against the bias of spring 406 and, as best shown in FIGURES 9 and 9A, will move away from panel 82 thereby disengaging lever 392 at point 396 and permitting wheel 380 to swing against operating wheel 422 which is mounted on shaft 424 having a knob 420 which extends into the operators compartment, as shown in FIGURE l. As will be seen from FIGURES l, 5, 9 and 9A, the operator may, by operating pusher rod 410, release lever 392 permitting wheel 380 to contact operating wheel 422. The operator then may operate knob 420 thereby causing the picture wheel 380 to rotate to a desired position. The interrelationship of wheel 380 and its associated mechanisms with the remainder of the master lock mechanism will now be described.

Flag 440 is normally located between panel 82 and picture 382 on wheel 380 so that a person entering the booth may not view picture 382 until the booth is closed. When the booth is closed and locked, flag 440 is raised in a manner now to be described. Rod 430 is slidably and pivotally connected to cam 70 by means of a pin 432 and, at the other end, is pivotally connected to a lever 436 which pivots about a pin 438. Flag 440 is xedly attached to the end of lever 436. Thus it will be seen that when cam 70 is in the position shown in FIGURE 5, that is when the door is locked, flag 440 is raised permitting the operator to view the pictures. When the booth is unlocked, however, cam 70 is rotated in a clockwise position. In this position lever 436 carrying ag 440 moves downward under the tension of bias spring 442 covering the pictures. In addition, lever 436 carries a pin 444 which coacts with notch 446 in member 448 which is xedly attached to master lever 200 thereby preventing counterclockwise motion of master lever 200 unless cam 70 is in the locked position, as shown in FIGURE 5.

On the side of wheel 380 opposite -ag 440 a lever 460 rests against bolt 386 and is pivoted at the opposite end by pin 462. Lever 460 is biased downwardly by means of spring 464 connected between lever 460 and master lever 200. Lever 460 is slid-ably engaged 'by means of keeper 466 on master lever 200, and carries on it a catch 468. In operation, when 'all things are in readiness and the operator breaks the toggle rformed by toggle rods 220 and 222 thereby permitting master lever 200 to move to the left under the influence of bias spring 204, master lever 200 and keeper 466 slide to the left, as viewed in FIGURE 5, -along lever 460 until keeper 466 engages catch 468. At this point the counterclockwise rotation of master lever 200 is arrested. This is the normal operating result. If, however, the picture wheel 380 is not rotated to the proper position, that is the correct picture is not showing in the window 90, then bolt 386 will not be in the position Ias shown in FIGURE 5. Unless bolt 386 is in the position shown, then lever 460 will move downwardly in response to the biasing action of spring 464 this downward movement of lever 460 will lower the level of catch 468 -so that it will slip freely through keeper 466 thus the counterclockwise rotation of master lever 200 will not be arrested iat the point previously indicated. Master lever 200 will then rotate to the left until arrested by slide keeper 206. This excessive counterclockwise rotation of master lever 200 locks both the entrance door' and the exit door in a manner to be described hereinafter. Thus, one who is unauthorized and does not know which picture to select will lbe locked in the booth.

Before describing the mechanism for locking the entrance land exit doors in response to excessive counter- -clockwise rotation of master lever 200, I will now describe the means and operation for resetting master lever 200 to the position shown in FIGURE 5. If the correct picture was selected ,and bolt 386 is in the correct position, then master lever 200 may be reset merely by operation of lever 74 causing cam 70 to rotate in the clockwise direction in the manner previously described. If, however, Ian unauthorized person has attempted to operate the mechanism and is therefore locked within the booth, it is necessary to `gain entrance to the m-aster lock mechanism chamber, in a manner to be described hereinafter, and to move master lever 200 back to its set position manually.

When master lever 200 is returned to its proper set position as shown in FIGURE 5, it is desirable to cause picture wheel 380 to rotate to remove the selected picture from in front of the window thereby making it impossible for a later person to enter the booth and merely leave the picture in the former position. This is done automatically upon the clockwise resetting movement of master lever 200 by means of a hook rod 470 which is fixedly secured to bracket 472. Bracket 472 is pivotally mounted by means of pin 474. Excessive downward motion of hook rod 470 is prevented by keeper 476 on master lever 200. As master lever 200 rotates in a g counterclockwise direction about pin 202, hook rod 470 engages pins 388 on picture wheel 380. When master lever 280 is returned to its set position by clockwise rotation, hook rod 470 engaging pins 388 causes picture wheel 389 to rotate. In addition7 picture wheel 380 and lever 392 are pulled toward master lever 280 and away from operating wheel 422 permitting lever 398 to reengage lever 392 lat point 396. Thus, the picture wheel 380 is returned to the position shown in FIGURE 5.

The locking of the entrance door 20 in response to excessive counterclockwise rotation of master lever 288 will now be described. Under normal circumstances, one who is not familiar with the pictures 'on picture wheel 38) would not be successful in -operating hand lock mechanism '768; nevertheless, whether or not hand lock mechanism 798' is operated, the excessive movement of master lever 280 in a counterclockwise direction causes the lower end of master lever 21N) to swing to the right, as shown in FIGURE 5. This causes lever 330, which is pivot'ally connected to master lever 200 by means of pin 332', to move to the right. Even if slide lock member 702 is free to move the excessive motion of master lever 200 will cause levers 330, 336, and 362 to move to the right engaging swinging pivot lever 366 which pushes catch 310 toward cam 78 engaging teeth 318 thereon. Thus cam 70 is locked preventing the person in the -booth from operating lever 74 and, consequently, his exit through door 28. By the same operation, that is the movement of rods 330 and 362, and lever 366, rod 344 is caused to move excessively to the right causing cam 350 to pivot excessively thereby locking the exit door in a manner to be described below.

Reference is made particularly to FIGURES 13 and 14. FIGURE 13 is a top view in partial section of the locking arrangement for the exit door into the vault or security area. FIGURE 1'4 is -a side view in partial section of the lock mechanism for the exit door. Handle 480, best `shown in FIGURE 13, `is attached by means of shaft 482 to 'a lever 484, best shown in FIGURE 14, having a notch 486 in the bottom thereof which engages a projection 488 on rod 498. Rod 49) has on the end thereof a lug 492 which is shown in FIGURES 13 and 14 and in FIGURE 5. Lug 492 is engaged by the notch in cam 350, las best shown in FIGURE 5. When cam 350 is in the position shown in FIGURE 5, that is in the normal locked position before operation of the master lever, movement to the left, as viewed in FIGURE 14, is prevented. On the other hand, if cam 358 is rotated to the fullest extent, as for example by excessive counterclockwise rotation of master lever 288 or normal rotation of master lever 28th while hand lock mechanism 700 is in the locked position, then cam 350 will move to en-gage the lower part of rod 490 thus preventing one from opening the door. If, however, the cam 350 is moved only partially, as it would lbe in normal correct operation, lug 492 will be centered in the notch in cam 350 and the entire rod 490 `will be free to move through the notch in cam 350 in response to movement of the handle 480 'by the operator in the booth. Movement to the left, as viewed in FIGURE 14, will permit Vbolt 492 to disengage bolt 584 thus permitting the exit door 48 to be opened.

Door 40 may be opened by one outside the booth at any time merely by turning knob 500 and thereby operating rod 504 by means of shaft 502, in the manner of a conventional door lock.

As mentioned previously in the preferred form of the invention, the doors `20 and 40 lare preferably made of bulletproof panel materials. In addition, in the preferred embodiment the inner panels of

doors

20 and 40 are slidably mounted on the uprights of the doors to permit the panel to slide vertically. The panels are biased upwardly; however, if an unauthorized person attempts to gain entrance to the booth yby carrying his weight on the `door panes to avoid placing his weight on the floor,

isA

with the consequent operation of the scale locking mechanism, then the door panels will move downwardly exerting the weight on the floor. The construction of the doors is described now with particular reference being made to FIGURES 10, 11 land 12. The description hereinafter lis made with reference to door 20; however, it is to be understood that door 40 is constructed in a similar manner, and in addition, the Wall-s of the booth may be similarly constructed. Referring now to FIG- URES 10 :and 11, panel 22 is provided with

tangle iron brackets

510 and 512 through which pins 514 Iand 516 extend.

Pins

514 and 516 are rixe'dly secured to upright members I518 :and 520. Panel -22 is biased in an upward direction by means of

springs

524 and 526 which are attached to panel 422 by means of a pin 528 and to the outside of the door, panel 24, by mean-s of

pins

530 and 532. It will be understood, of course, that similar angle liron brackets 548 and 542 :are provided in the lower portion of panel 22, as shown in FIGURE l0. It will be seen then, that panel 22 will move downwardly bearing the persons Weight against the floor in the same manner as if the person was standing on the floor.

With reference now particularly :to FIGURES 15, 16 andV 17, the operation of the lock for the 4rear panel access door to the master lock mechanism chamber will be described. Lock 88 is shown generally in FIGURE 2, and is shown with more particularity in FIGURE 15 and FIGURE 16. Lock 88 comprises a key slot lock 610 for receiving key 612 `and is of a modified commercial variety. When the correct -key 612 is inserted in the slot 610 turning the key will cause pivotable bolt 614 to turn in response to the keys turning thereby permittinfg the door formed by

panels

84 and 86, as shown in FIGURE 2, to be opened. Insertion of the key 612 into the slot "610 causes a slidable insert 1620 as best shown in FIGURE 116, to move Ibetween contacts 622 and 6124 thereby :completing an electrically conductive path between the said contacts. Contacts 6.22 and 624 `are part of a switch y6'30 which is shown schematically in FIGURE 17. As will be apparent froml FIGURE 17, the closing of switch 630 will complete the circuit from transformer 6132 through switch 630 to the bell alarm means 634. Thus even though a correct key is used an alarm is given if an attempt is made to open the access door to the master lock mechanism chamber. In addition to switch 630 ya second switch 640 is shown which is Iclosed with similarly completed cir-cuit from transformer 632 to alarm means `634. Switch 640 is shown in FIGURE 5 having a pushbutton 642 which is operated by cam 70. Thus, when the person enters the booth and locks the door thereby moving cam 70 into the position shown in FIGURE 5, pushbntton 642 is depressed closing the normally open switch contacts 640 completing the circuit between transformer 632 and bell 634 th'us giving an alarm. FIGURE 17 also shows the schematic representation of switch 92 shown in FIG- URE 1 'and of light '94 shown in FIGURE 2. The purpose of light 94 is to permit the operator to mo-re clearly view the pictures 382 on the picture wheel 380.

In o-rder to more clearly explain the operation of the mechanisms of the holdup proof booth the following two examples will be given: First, the operation of the booth by an authorized person in the normal manner will be 'described and, second, the operation olf the mechanisms if an unauthorized person attempts to enter the booth will be described.

First, yas the operator approaches the booth he may open the door 20 by turning the handle 32. Of course, it would be possible to equip the door 20 with a conventional key lock on the outside thereby requiring the operator to have a key and preventing unauthorized persons tfrom initially lgaining entry into the booth thereby precluding mere curiosity seekers from entering the booth. When the operato-r has entered the booth he rst .closes door 20 by means of handle 32. When door l l 20 is fully closed operating `arm 28 engages hook 142 on locking rod 140, best shown in FIGURE 4, causing locking rod 140 to move to the right thereby freeing locking plate 126 on one side for upward movement in response to the weight of the operator.

The operator then locks door 20 by moving lever v'74 downwardly causing shaft `66 to rotate cam 72 into slot 34. The rotation of cam 7&2, best shown in FIGURE 4, in addition to locking door 20 causes lever 130 to pivot on ifulcrum 134 thereby releasing the other side of locking plate 126 for upward movement in response to the weight of the operator on Hoor 100. The downward movement of lever 74 in addition to locking door 20 by means of cam 72 causes .cam 70 to rotate in a counterclockwise direction moving the lower portion downward aga-inst pushbutton 542 on switch 540 giving an Ialarm to indicate that a person is attempting to enter the security room or vault. This |would prevent persons who may be working in the vault from being surprised and may give an indication to other persons to be on the lookout lfor a possible attempt by an unauthorized person to enter the vault.

The downward motion of lever 74 and lthe consequent rotation olf cam 70 causes rod 430, shown in FIGURE 5, to move downwardly lifting ag 440 from in fro-nt of the pictures in the manner previously described. The operator then turns lights 94 on by means of switch 92 thereby enabling him to clearly view the pictures 382 on piet/ure wheel 380. It would then he necessary for the openator to operate pusher 410 causing lever 398, FIG- URES and 9, to disengaige lever 396 thereby permitting picture wheel 380 to move into engaging relationship with operating wheel 4212. Operating wheel 422 may then he turned hy means of knob 420 in the operato-rs compartment as shown in FIGURE 1. The operator must be able to recognize the designated picture in order to place it in front of the window in the proper position. Having selected the correct picture, the operator then must place his right hand in hand lock mechanism 700, shown in FIGURE l, and with his Ile'ft hand operate the pusher cam 232, shown in FIGURE 5, by means of crank 236, shown in FIGURE 1.

When pusher cam 232 is operated, the master lever 200 is permitted to move to the left in response to spring 204 and bias mechanism 240 until keeper 466 contacts catch 46S thereby arresting the motion of master lever 200. As shown in FIGURE 5, this counterclockwise rotation of master lever 200 operates through rod 330, lever 336, and rod 344 to rotate cam 350 until the lug 492 is centrally located in the notch in cam 350. This operation assumes that the hand of the operator has the proper dimensions and that slide lock member 702 moves freely. The operator may then turn handle 480, shown in FIG- URES l and 13, thereby causing bolt 490` to move through the notch in cam 350 and, at the other end, disengage rod 504. This frees the exit door 40. The operator can then open exit door 40 merely by pushing on it and can enter the security area or vault. Of course, since the alarm was given upon the operation of lever 74, the persons inside may be on the alert in the most unlikely event that an unauthorized person could gain entrance in spite of the protective devices of the holdup-proof booth.

When the operator wishes to exit through the booth he merely enters the booth through door 40, closes the door, and raises lever 74. The raising of lever 74 unlocks the exit door 20 and, in addition resets master lever 200 for the next operation and turns wheel 380 to a different position as previously described. The operator then may make an exit through door 20.

In the next example it is assumed that an unauthorized person is attempting to gain entry into the vault through the holdup-proof booth. The person opens door and enters the booth in the normal manner. 'Of course, if door 20 is equipped with the ordinary commercial door lock, now shown for purposes of clarity, the person may,

i for movement.

in addition, be required to possess a key of the proper type. Once in the booth, the person then closes door 20 and enters in the normal manner freeing one side of locking plate 126, as shown in FIGURE 4, for movement in the normal manner. When the person then operated lever 74 door 20 would he locked behind him by the mechanism previously described. Assuming the least favorable circumstance, that is where the unauthorized person has information which might be available from -an operator who had either voluntarily or under coercion divulged his information, the operator then turns on light 92 and perhaps operates pusher 420.

Since it is virtually impossible to describe the characteristics of a single picture, especially as would be the normal case in a holdup-proof booth where the pictures wer-e all of very great similarity, it would be extremely difficult if not impossible for one to select the correct picture. The picture wheel 380 is shown having eight pictures thereon; however, this number may be enlarged. In addition, many visual devices may be used on picture Wheel 380. Thus it will be seen that it would he very easy to provide pictures or other visual devices which are virtually incapable of verbal description but which may be recognized by an operator. It should be pointed out that the unauthorized person has only one chance and if the correct picture is not selected he will be locked in the booth as described.

Assuming the unauthorized person selects an incorrect picture, he lthen operates crank 236 thus permitting master lever 200 to move to the left, but since the bolt 386, as shown in FIGURE 5, is not in the proper position, lever 460 will fall below its normal position and keeper 466 will not engage catch 468 and master lever 200 will move to its extreme position until stopped by slide guide 206. As previously described, this excessive movement of master lever 200 causes excessive motion of rod 330 and consequently of lever 336, rod 344 and rod 362, having the effect of locking the entrance door by causing catch 310 to engage teeth 318 on cam 70 and by causing cam 350 to rotate excessively so that the bolt 490 is not free to move through the notch in cam 350. Thus, not only is the exit door locked bu the entrance door as well and the unauthorized person is locked in the booth and cannot escape until the door is opened by a person from within the vault.

There is, of course, a very small possibility that the unauthorized person may accidently select the correct picture thereby placing bolt 386 in a proper position and preventing excessive motion of master lever 200; however, the person must also insert his right hand into hand lock mechanism 700 in order to free slide lock member 702 Since the operating member of lock 700 can be very precisely adjusted to conform to the measurements of the authorized operators hand, there is virtually no probability than an unauthorized person would coincidentally 'be able to operate the lock. Thus, since the unauthorized person could not operate the lock, slide lock member 702 could not lbe free for movement and even if master lever 200 moved only the correct distance the failure of slide lock member 702 to move would cause lever 336, as shown in FIGURE 5, to pivot about its lower end engagement with slide lock member 702 'causing rod 344 to rotate cam 350 about pin 352 to engage the lower portion of bolt 490 thereby locking the exit door. In addition, the pivotal action of lever 336 would cause bar 362 to move to the right engaging lever 366 and causing catch 310 to engage teeth 318 on cam 70 thereby locking the entrance door. Thus it will be seen that an unauthorized person would be locked in the booth in the manner previously described even though he should accidentally select the correct picture on picture wheel 380.

It will he apparent to those skilled in the art there may `be many variations of the preferred embodiment described herein without departing from the spirit of the invention. For example, as new and improved bulletproof materials i3 are developed they may be used in the construction of the booth to give greater safety to those who may be enclosed therein or to prevent one enclosed therein from endangering persons on the outside. In addition, the various operating mechanisms may be modified slightly Without departing from the concept of the invention.
