RECORDER FOR REGISTERING LOCKS.

Specification of Letters Patent. I

Patented Jan. 6, 1920.

Application filed April 7, 1919. Serial No. 288,080.

T 0 all whom it may concern:

Be it known that I, CLINTON E. LARRABEE, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Recorders less remote mechanism over suitable circuits to record the particular key used to operate the lock; the particular door or the special lock attached to it which is operated, a character of figure which indicates whether the key was inserted from the outside or the inside, and other data of a like useful nature.

The invention upon which the present application for Letters Patent is based 'isan improvement in the recorders or the means employed in such systems for receiving and recording in permanent form, the information of the nature referred to. r

The mechanism of my improved instrument is designed to be operated either manually or electrically to record the data desired. It has provision for recording the signature of an employee in conjunction with the time at which the signature was made, and other items of information, such as marks or symbols indicating the door in which a lock is located, the particular key used and such others as'have been specified above. It is so arranged that when being used as a signature or autograph recorder, certain parts only are operative while the others are locked against operation, while, when used in conjunction with the automatic mechanism of the lock, the previously locked parts are brought into operation as well as such of the other parts as may be necessary.

The apparatus is further designed in such 'ation with a lock to automatically record, it cannot be operated manually and vice versa, and it may be provided with means for giving a signal or alarm when operated at certain predetermined or unusual times.

The invention resides in the construction of the elements and in their novel combi:

nation to form a more effective and practical mechanism and one more dependable and reliable in operation than those which v preceded it, and hence no further general statement of its nature and purpose will be required for itsproper comprehension.

' In the accompanying drawings, which illustrate'the details of the mechanism,

atite recording mechanism.

Fig. 8 is an electrical diagram of the system including a plurality of recording looks.

The character of the locks used for operating the recorder is not of the essence of this invention, and may be greatly modified. In a copending application, filed November 11, 1918, Serial No. 261,976, I have shown in detail such a lock andreference may be had to the drawings and descriptions of that case for such information as may be required as to the actual construction of suchv locks.

In the apparatus of the present case the parts are properly associated in a casing 1, having an inclined front 2, with a window or opening 3 therein which may be either I normally open or stand normally closed by turning of the shaft in a counter clockwise direction through a given are rotates an arm 10 fast to the shaft to which is pivoted a link 11 connecting said arm to a bell crank lever 12 on a shaft 13, the end of which is formed as a cam which engages a roller 14 on a lever 15, see Figs. 4 and 6.

A lever 16,- see Figs. 5 and 6 is fixed to a hub 78 on shaft 17 and having an extension 79 which interlocks or engages with a sleeve 81, which carries a projection 19 that is in the path of a bent projection 83 from one of the plates 20 that carry the printing pad 21. The lever 16 has a bent or turned over end 18, as shown, which lies over the lever 15, and by the movement of the latter sleeve 81 is rotated clockwise and this operates through the projection 19 to throw the spring actuated plate or lever 20 carrying the printing pad 21 against the strip 6 and thus print the set up characters which are in the printing position.

On a shaft 27 is mounted so as to turn thereon, a lever 26, connected by a link 30 to a pawl mechanism 31 which when shifted operates to turn a ratchet wheel 32 about a shaft 33, in a counter-clockwise direction, and to thereby wind up the paper reel 8 and feed the record sheet. Movement of sufficient extent to feed the paper so as to receive autographs is accomplished by the mechanism which opens the shutter 4.

On a shaft 27 is fixed a crank 28 to which crank is pivoted a link 29 that engages by a slot and pin connection with the lever 12, so that when the main shaft 9 is rotated the shaft 27 is also turned and in an anti-clockwise direction. Normally the window 3, in

the inclined top of the casing is closed by the sliding plate or shutter 4, but this plate is connected by a link 38, with the lever or crank 28, so that when an employee operates the instrument manually, the window is opened to permit him to write his name on the record'strip. It willebe observed that by reason of the pin and slot connection be tween the lever 12 and the link 29 that shutter is not withdrawn until the main shaft9 has been turned through a substantial arc.

Keyed to the shaft 27 is an arm or lever 95 and in the path of the end of this arm is a projection or turned over portion 96 of the lever 26. Hence when the shaft 27 is turned in an anti-clockwise direction by the lever 28 and link 29, this arm engages the said turned over portion 96 of lever 26 and the latter is moved through a substantial arc and thereby imparts a feed movement to the pa per, ample to receive another autograph.

The feed movement of the paper produced by the movement of the lever 26, also feeds the inking ribbon 22, which is carried by spools 23 on vertical spindles 24 having gear wheels 25 at their lower ends by the prises a pawl 34 pivoted to the lever 26 and operating on a ratchet wheel 35 mounted on a shaft 36, on the ends of which are gears 37. Figs. 1, 2 and 4 which engage altermeans shown in Figs. 1 and 2 which comnately w1th the gears 25 on spindles 24 and thereby feed the inking ribbon step by step.

The time type wheels 40 are shown in Fig. 3 as being in gear with a spindle 39, which is driven by a suitable clock which is not shown in the drawing, but in order that a minute type may be presented squarely to the printing pad whenever the latter is operated, I employ what is termed an alining pawl 41, Fig. 2, which is mounted on a lever 42 and connected by a link 43 to the lever 20.

The latter being oscillated to effect the printing therefore moves the pawl 41 which engages with a ratchet wheel 44 and thereby alines up the minute type wheel so that whole minutes only will be printed and not parts of one or two adjacent numbers.

As above stated, the apparatus is so arranged that while being manually operated it can not be operated by the lock mechanism. This may be accomplished by the means shown in Fig. 5. A lever 45 is pivoted in the instrument in such position that an insulatingpin 46 carried by it rides on a cam 47 on the main shaft 9. When the main shaft is turned from its normal position the cam raises the lever 45 and causes it to close two contacts 48 which complete a circuit to'the lock or looks connected with the recorder and locks the mechanism thereof so that it can not be operated until the completion of the manual operation of the recorder, when the circuit between contacts 48 is again broken.

By the above described use of the device the employees of a store or any place of business may register their arrival or departure and the time thereof, but the primary object of the apparatus is to record the exact time when any given look was operated either to open the place or lock it up, and

who was responsible for doing these things.

current impulse in a magnet shifts the pawl 52 to the position shown in Fig. 5, and on the cessation of such impulse a spring 53 and prevents its return until after the printing operation, when a cam 57 on a shaft 58 engages 'a bell crank lever .59 one end of which engages with a pin '60 on a lever 61, and which in its movement engages and re leases the retaining pawl and also engages with the arm of the armature 51 and lifts the pawl 52 oil the .toothed segment so that the type segment is restored to" its normal position after each cycle of operation.

The type segments for each magnet are similar in construction and operation. The insertion of a given key into a given look from a given side of the door may, for example send four impulses to one magnet to represent thekey used, two impulses to another magnet to'indicate the lock'operated, and one impulse to the third magnet to indicate that the key was inserted from the out-V side of the door. These signals set up the respective type segments in proper position to print the'data, and after the printing is efi'ected all the parts resume their normal positions.

' After the proper impulses have been sent from and by the lock mechanism to the type setting magnets 49, and the type segments have been shifted soas to bring the proper type thereon into the printing position, a single impulse is sent from the lock to a magnet 62. This magnet, when energized,

attracts its armature 63 which carries an" insulating plate or bar 64: that engages and brings into contact'with each other the two terminals 65 that close the circuit to a motor 66 mounted in the lower part of the recorder casing. As this impulse-is momentary only, a pivoted pawl67, with a latching end, engages a projection on the a-rma-" ture 63 and holds the latter in attracted position and the terminals 65 in contact until the shaft 58 has made a complete-revolution, when the latch is released by a projection or cam 69 engagingthe end of the latch 67 and thus releasing the armature and permitting the terminals 65 to separate.

The power for operating the recorder when operated by the lock mechanism is furnished by this motor 66. A gear 71 on themotor shaftimparts rotationto a vertical shaft 72, and in turn by a worm 73 imparts rotation to the shaft 58. To one end of this shaft thereis eccentrically connected a link 74 which is pivoted to a lever 75, like the correspondin formed as acam t at works on apin 76'on a plate 77, see Figs. 1 and 6, that'is designed to perform the same printing operation as plate or lever.:15, and in the same way. As the motor shaft makes one complete revoluend of the lever 12, is I should record or. print from the time type Whee-ls only, but when operated by a lock it should print from both the time type wheels and the indicating segments. This is accom plished by the means shown most clearly in Fig. 6. In thisfigure, as has been set forth, the plate or lever 15 is fixed to the hub 78 withthe extension 79,. which turns freely on the shaft 17. The said hub,

by its interlocking engagement with sleeve 8-1, operates the printing pad for the time type Wheels only when the pin 14 is engaged by thecam end of lever 12 there being no connection between those parts and the shaft 17.

On the other hand, should the lever 75 be operated by the lock mechanism, the pin 76 -is engaged Which moves the armature plate 77 and thus engages a bent lever 90 fast to the shaft 17, which is thereby rotated. The shaft not only carries a projection 86, which engages with a stop 87 on one of the plates or lever 88 connected with the pad for the indicating segments, similar in all respects to the projection 19 and stop 83 of Fig. 5 and thereby operates that pad, but the shaft 17 also carries a similar projection 82 that engages a stop 91 on one of the plates connected with the printing-pad for the time type wheels, and operates that pad also. The several projections and stopsiabove described are not illustrated in detail except that in Fig. 5, but they are all similar in general construction and may 'be very ed to the lever 26, turning about the shaft 27 1 as a center. By reason of the slot and pin connectionjthe movement thus imparted to the lever 26 is not as extended as when it is moved by the crank arm 95, and a corre- "spondingly shorter feed movement is therefore imparted to the papers.

The above description covers so far as is necessary for one skilled in this art the knowledgev to. construct and to operate the recorder. It remains therefore to describe, only in such general way as is requisite to an understanding of the present invention, the nature of the system with which the device is more particularly designed to be used. For this purpose reference may be had to Fi 8.

In this Egure A indicates one lock, B another or others. and G the recorder Which has been described in detail above. At the lockare the necessary terminals for the circuits that carry to the recorder the current impulses for operating the three magnets 49, such magnets having a common return wire. The outgoing circuits are numbered 100, 101, and 102, and the common return by 103.

In addition to these ircuits there are also those which lead to the group of devices at the upper right hand corner of the sheet including a circuit 105, for the motor 66,

the locking and the non-interfering circuits.

It has been explained that when an employee turns the shaft 9 to operatethe recorder manually that a circuit to the lock is closed by the cam 47 that prevents the lock from being operatedby a key until after the manual operation is complete. To provide for the converse of this, and, prevent manual operation while a key is being turned in the look, I employ an electro-mag net 109, Fig. 5, which operates a pivoted. armature lever 110 that when the magnet is energized engages a notch in the cam 47. Whenever a key is inserted in a lock and turned it closes contacts in the lock that complete a circuit 111 including the magnet 109, and so locks the main shaft 9 against rotation by hand, until the key has been turned back and withdrawn.

Between the two wires 106 and 107, the former connected with the lock mechanism and the other to the recorder terminal frpm the in and'out magnet 49, is a switch 108 and during such hours as the lock should not be operated at all a plug may be inserted in this switch so that a current will be sent over this circuit whenever a key is inserted in the lock from either side. This circuit may lead to a burglar alarm station at any convenient place and set off an, alarm which gives notice that an unauthorized use is being made of the lock.

It will be understood that except so far as their respective functions are concerned the elements shown and described herein as making up this system may be modified indefinitely in construction.
