PERMUTATION-LOCK FOR AUTOMOBILES.

marked thereon, which form a part of this specification.

-My invention relates to lmprovement-s in permutation locks for automobiles, my object being to provide a device of this class which shall make it practicable for the chauffeur or other person in charge of an automobile to quickly and securely lock the same against thieves or other evilly disposed persons who might be inclined to use the machine in his absence.

My improved lock is mounted in operative relation with the steering post of the machine and is equipped with a bolt adapted to enter any one of a series of recesses with which the steeringpost is provided, when the bolt is in the locking position. This bolt passes through a hollow coreor spindle inwhich a pallet is located, the said core being surrounded by rotary tumblers, which whenproperly adjusted, have slots properly alined to permit the movement of the bolt from the looking to the unlocked position,

by virtue of the fact that the pallet is adapted to enter the alined slots of the tumblers. WVhen, however, the bolt is in the locked po sition and these tumblers adjusted so that said slots are out of alinement, the bolt cannot be withdrawn or moved from the locking to the unlocked position, except by bringing the tumblers into proper position, and this can only be done by a person who knows the combination.

Eachtumbler consists of a shell angularly arranged. around the core and carrying a removable disk, said shell being provided with a series of radially disposed slots while the disk is provided with a single slot only. The disk is numbered on one of its faces with the characters 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The combination is changed by changing the position of one or more of the disks within their respective shells. Each Specification of letters Patent. Patented Aug. 28, 191'? Application filed May 15, 1915.

Serial No. 28,441.

tumbler works in cooperation with a spool which is splined upon the core and consequently, has no rotary movement in respect thereto. This spool carries spring-actuated balls adapted to engage radially disposed recesses formed in the disk of each tumbler. One of these recesses in the disk is cut en tirely through to form a slot which regis ters with one of the series of slots in the tumbler shell. Each disk has recesses in its exterior or peripheral edge adapted to receive a tongue formed on the shell. The combination of the lock is changed by changing the relative position of one or more of the disks within the shell, as hereinafter more fully explained.

The bolt, the spindle and the series of tumblers constitute the lock proper, and are mounted in cooperative relation with a relativelv stationary sleeve through which the steering post of the automobile passes. Nor mally, or when the'machine is regularly in use, the bolt is withdrawn from its locking position and the steering post released, whereby it may be operated in the usual manner.

Having briefly outlined my improvement, I will'proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof. In this drawing,

Let the numeral 5 designate the lock proper, composed of a hollow spindle 6, a

pallet 7 four tumblers 8, two spools 9 and a bolt 10.

When the device is in use as an automobile look as disclosed in this specification and the accompanying drawings, the opposite extremities of the hollow spindle, which is cylindrical in shape, enter cavities 12 and 13 formed in the upper and lower bearings 14 and 15 which are mounted by means of brazed collars 16 and 17 on the relatively stationary sleeve 18 through which the steering post 19 of the machine passes, the said post being normally rotatable. within the sleeve.

As illustrated in the drawing, the steering post within the sleeve and approximately centrally arranged with reference to the lock, is equipped with a bushing 20 which is provided with a series of perforations 21 which are adapted to receive the inner extremity of the bolt 10 when the latter is in the locked position (see Figs. 3, 4, 6 and 15). V

Thecollar 17 which connects'the end bearing 15 with the sleeve 18 of the steering post, is brazed thereon or made fast thereto in any suitable manner; while the collar 16 which connects the upper bearing 14 with the sleeve 18 has a limited sliding movement on said sleeve when the boltand pallet are in the unlocked position.

Located within the recess 12 of the bearing 14, is a thimble 22 which is threaded into the bearing at'the upper end of the cavity, which is-counterbored for the pur-. pose. The lower portion of this thimble is spaced circumferentially from the outer wall of the cavity to, leave room for the upper extremity of the hollow spindle 6. The portion of the thimble which extends into the portion of the cavity surrounded by the adjacent extremity of the spindle, is beveled as shown at 23, while the portion of the thimble opposite the bevel is perforated as shown at 24 to receive teeth 25 formed on extensions 26 of the spindle members 27 and 28, so that when the bolt and pallet are in the locking position, the upper bearing 14 is locked against endwise movement. Consequently, it is impossible when the bolt is in the locked position to move the bearing 14 in the direction of the axis of the steering post. 'lVhen, however, the bolt is in the unlocked position, the pallet is moved'laterally a sufficient distance to disengage the teeth 25 from the opening 24 of the'thiin'ble, thus permitting the bearing 14 tov be moved to the dotted line position, making itfpracticalble to remove the entire locking mechanism from the steering post. The bearing 14 is normally temporarily held in position on the sleeve '18 by means of hollow projections 29 arranged on' opposite sides of the portion of the collar 16 which surrounds the openings 32 formed in the body of the sleeve.

Hence, even if the pallet is moved to disengage its teeth 25 from the thimble of the bearing 14,.this bearing, together with its collar, will normally maintain its position, causing the adjacent end of the spindle to remain within the cavity 12 of the bearmg. A slight pull, however, upon the projections 29, will force the balls 30 into the hollows of the projections and againsflthe springs 31, making it practicable to move the collar and its bearings 14 sufliciently to allow the body of the lock to be disengaged from the sleeve of the steering post. This sleeve is provided with a stop pin 33, which limits the upward movement of the collar, since it is not desirable to allow this collar any more movement than is necessary to permit the easy removal of the lock. As soon as the bearing 14 and the collar 16 are moved far enough to permit the disengagement of the lock proper, a centrally located collar 34 which carries a yoke 35 and which centrally engages the lock between the innermost two tumblers, is also movable in the direction of the axis of the steering post and endwise with reference to the lock in order to permit suflicient endwise movement of the lock to disengage the lower extremity of the spindle from the cavity13 of the lower bearing 15. When the central collar 34 is thus adjusted, the opening 36 through which the bolt passes, is thrown out of register wlth the zone of the perforations 21 of the bushing 20, by virtue of an opening 1n the sleeve 18, which the bolt enters, said opening being elongated to permit the movement of the collar 34 for the aforesaid purpose, since the inner extremity of the bolt, when disengaged from its perforation 21 of the bushing 20, may still be within the opening 37 of the sleeve, though as illustrated in the drawing (see Fig. 14), when the bolt is in the unlocked position it is completely disengaged from the opening 37. This central collar 34 is connected with the sleeve 18 by a suitable fastening device 38 which enters an opening 39 in thesleeve, whlch is also elongated (see Fig. 6) to permit the adjustment of the central sleeve carrylng the yoke 35, as heretofore explained.

The hollow spindle 6 is perforated mid way of its length as shown at 40 to receive the shank or reduced portion 41 of the bolt j 10. This opening when the parts of the g lock are assembled, is in register with the openings 36 and 37 of the collar and the sleeve 18, respectively, and also in alinement with the zone of the bushing 20 containing the perforations 21, so that as the bolt is manipulated, it may be caused to pass through the openings 36 and 37 and enter one of the openings- 21 of the bushing or collar 20 carried by the steering post, as heretofore explained.

The shank 41 of thebolt is transversely slotted as shown at 42 to receive the pallet 7 which is composed of the two members 27 and 28. Each of these members is provided with upper and lower projections 43 and 44 which fit closely within the hollow or cavity 45 of the bolt. The member 28 is secured to the bolt by means of a securing pin 46, which is passed through the upper projection 43 of the pallet member and through the bolt on opposite sides, being secured in place by upsetting its extremities or in any other suitable manner. By virtue of this construction, this pallet member must move with the bolt. The projection 43 of the other pallet member 27 is provided with an elongated opening 47 through which the fastening pin. 46 also passes. Normally, the pallet member 27 is held inwardly as far as possible within the spindle, that is to say, so that the outer extremity of the slot 47 is engaged by the pin 46. This is accomplished by virtue of the fact that the upper portion. of the bolt is surrounded by a sleeve 48 having an interiorly projecting shoulder 49 upon which the lower or inner extremity of a spiral spring 50 acts, the upper extremity of said spring bearing against a shoulder 51 formed by the enlarged upper extremity 52 of the/bolt. Extending downwardly or inwardly from the shoulder 49, the sleeve is provided with pins or tongues 53 which engage the upper edges of the two pallet members and serve to force them inwardly or to their lowest limit of movement within the hollow spindle, which however, has its upper portion longitudinally slotted on opposite sides of the bolt to allow the pallet to more out of the spindle when the tumblers are properly adjusted. to bring all of the disk slots into alinement with the slot of the spindle. This spindle slot is designated by the numeral 54.

i vhen the tumblers are in position to prevent the movement of the bolt for unlocking purposes, if an attempt is made to no tuate the bolt, it can be moved for a short distance, but not far enough to disen age it from its opening 21 in the bushing or collar of the steering post. The slight movement permitted is due to the fact that the pallet member 28 is cut away or notched in four places, as shown at to malte'room for the edges of disks 56, there being four of these disks. one for each tumbler, l i hen the tumblers are adjusted for locking purposes as just explained, the of the four disks 56 will act to prevent the pallet member 27 from moving, as these edges of the disks will act upon the upper edge 57 of the member 27 to prevent any movement thereof. However, the bolt is permitted a slight movement or that equal to the length of the slot 47 through which the pin 46 passes. This movement of the bolt necessarilycarries the pallet member with it,

whereby the relatively narrow portions 98 of this pallet member are caused to enter slots 58 formed in the shell members 59 of the tumblers, whereby the latter are prevented from rotation. In other words, if an e'villy disposed person is attempting to unlock the machine, he will naturally pull on the bolt and as he does so, the sleeve 4-8 as it is moved against the spring 50, will act upon the shoulder 51 of the bolt and move the latter far enough to project the narrow parts 98 of the pallet member 28 into slots 58 of the shell members of the tumblers, as just described. This will lock the tumblers against rotation on the spindles and further frustrate any attempt on the part of the thief to solve the combination of the lock. At the same time, the permitted movement of the bolt is not sufficient to disengage it from the steering post.

Arranged on opposite sides of the bolt when the parts are assembled, are two collars 99 which are provided with top and bottom recesses 60 and 61, whereby they are adapted to receive the bolt. the upper recess of each collar having an extension 62 to receive the corresponding pin. or tongue 53 of the bolt. The pallet members are further recessed as shown at 63 to receive the inner edges 64 of the collars 99. TV ere it not for the recesses 63, the edges 64 of these collars would prevent this movement of the bolt, inasmuch as they would form stops against the movement of the pallet members. Arranged adjacent each collar 99 and on opposite sides of the bolt and surrounding the hollow spindle, is a tumbler 8 composed of a shell. member 59 and a disk member 56. Each shell member has a relatively large circumferential flange 65 which is corrugated or notched as shown at 66 to facilitate manipulation. This flange extends considerably beyond the annular part 67 of the shell. This annular part extends outwardly from the bolt and forms a cup adapted to receive the disk member 56 of the tumbler. The

shell member has a series of radially disposed slots 58 extending outwardly from a central opening 68 and in communication with said opening. The disk 56 has a single slot 69 which when the disk is inserted in the shell, registers with one of the slots 58 of the shell. Then the parts are assembled, one of the slots 58 is always in alinement with the slot 54' of the spindle, but unless the tumblers are so adjusted that the disk slots 69 are in alinement with the slot 54 of the spindle, the bolt cannot be moved sufficiently for unlocking purposes. There are ten slots 58 in each shell member of each tumbler. Each disk member 56 is provided with nine recesses 7 0 which are coincidently positioned with relation to a corresponding number of the slots 58 of the shell member; while the slot 69 of the disk is in register with the other slot 58 of the shell member. Each disk 56 is provided with characters upon its recessed face, these characters in the specific construction shown in the drawing, consisting of 0 and the numerals 1 to 9-, inclusive. The setting70 of the combination depends upon the position of each disk 56 within its shell 59. This shell is provided with an interiorly projecting tongue 71 adapted toenter any one of a series of peripheral recesses 7 2 formed in the disk of the tumbler. These recesses "72 are arranged in radial alinement respectively, witlh the ten characters on the face of the dis Cooperating with each tumbler is the spool. 9 which is provided with an opening 7 a to allow it to be applied-to the spindle. This spool is also provided with a tongue 94: adapted to enter a groove 75' of counterpart shape formedin the spindle, whereby the spool when applied to the spindle issplined thereon. This spool is also slotted both as to its body portion and its flanges, as shown. at 95, to coincide or register with the slot 54 of the spindle when the parts are assembled. The periphery' of each flange 76 of each spool is provided with an exterior proj ection 77 forming a, stop to limit the travel of each tumbler in bothldirections, by reason of the fact that thesaid stop lies in the path of the tongue 71 carried by the annular part 1 67 of each shell member of any tumbler; and

the characters on the fa'ceof each disk of the tumbler are so arranged that if the recess 7 2 which is opposite the zero character, is caused to engage the tongue 71 of the shell member when the disk is applied to the lat ter, if the said tumbler is turned toward the right, for instance, untilthe tongue 71 which extends the entire length of the annular part 67 of the shell member is caused to engage the stop 77 of the spool, the slot 69 of the disk will be in alinement with the slot 54: of the SPlHCllG, and consequently, in alinement with the slot 95 of the spool, and consequently in position to "allow the bolt to be moved to'the unlocked position, since the pallet members may be moved outwardly with the bolt into the slot 69 of the disk, as wellas the slot95 of the spool. Again, if in assembling the disk and shell of the tumbler, the recess 7 2 of the disk opposite the numeral 9 be applied to the tongue 71 of the shell, the operator in solving the combination will first turn the tumbler toward theright, for instance, until the tongue 71 engages the stop 77 of the spool. Tie will then turn the tumbler toward the left nine spaces or steps corresponding with thedistance between the recesses 70 of the disks and the slots 58 of the shell. When each one ,of these steps is completed, the operator is notified thereof by the reason of a click or low sound due to the engagement ofa ball 7 8 carried by the spool and acted on by r a spring 79 with a recess of the disk.

When nine of these clicks have occurred,the operator will. know that the slot 69 is in the proper position for unlocking purposes or to permit the pallet to enter this slot of the disk, and this is all that is necessary in order to solve the combination of the lock. In case the disk 56 is so applied to its corresponding shell that the recess 7 2 opposite the numeral 4-, for instance, is caused to engage the tongue 71 of the shell, the operator will first turn the tumbler to the right as far as possible and then to the left until four clicks have been counted, in which event, the slot 69 will be brought into position for unlocking purposes.

Each spool 73 is arranged to cooperate with two tumblers of the lock, the stops 77 of each. flange engaging the tongue 71 of the adjacent tumbler. Consequently, there are two click balls 78, both of which are acted on by the same spiral spring 79 which is located betweenthe balls and incased by a tube 80 which is located between the two flanges of the spool. Each of these flanges is recessed as shown at 81. to allow the click ball to protrude sufiiciently for the purpose, but preventing its escape.

As illustrated in the drawing, the lock is equipped with or includes four tumblers, all of which are identical in construction with the description just given. These tumblers are arranged in assembling the lock, two on each side of the bolt. The first two tumblers are placed adjacent the two collars99 and withtheir peripheral flanges 65 next 'to thesaid collars, their annular or cup-shaped members extending outwardly therefrom. The next two tumblers are re versely arranged so that their annular or cup-shaped members 67 engage or abut the outer edges of the corresponding parts of the adjacent tumblers.

When so arranged, the charactered itaces of the two disks 56 and the two tumblers are caused to face each other and the solution ot'the combination of the lock depends upon the proper adjustment of the tumblers with relation to the positions of the disks 56 within their corresponding shells 59. If it be assumed thatthe disk of one tumbler is so applied to its shell that its recess 72 opposite the numeral 1, engages the tongue 71 of its shell; and the disk or another is so placed that its recess 72 opposite the numeral 2 engages the tongue 71 of its shell; and the disk of. another tumbler so arranged that its recess '7 2 opposite the numeral 3 receives the tongue 71 of its shell member; while the recess 72 opposite the numeral 4 of another disk be caused toengage the tongue 71 of its shell, all that will be necessary in solving the combination will be to first turn all of the tumblers toward the right, for instance, as far as they will go, after which, one tumbler will be moved toward the left, one space or until one click is heard, after which another tumbler will be moved toward the left two spaces or until .two clicks are heard, while the remaining tumblers will be respectively moved toward the left three or four spaces, or until three or four clicks are heard. This will bring the slot 69 ot the disks of all the tumblers into alinement with the slot 54; of the spindle and with the slots of the two spools, in which event, the bolt may be moved to the unlocked position. Thus the pallet members will both be allowed to enter the slots 69 of all the disks. At the same time, the hooks 25 of the pallet members will be disengaged from the opening 2%. of the thimble 22, thus making it practicable to slide the bearing member 1a endwise of the lock and longitudinally oi the steering post by the movement of the collar 16 on the sleeve 18 far enough to remove the lock from its position in cooperation with the steering post, as heretofore described. The bearing Li, however, is held securely in place when the bolt is moved to the un locked position by means of the spring-actuated balls 30 of the collar 16 which engage the openings 32 of the sleeve as heretofore described; and the movement of the' bearing 14 will never take place except when it is necessary or desirable to remove the body of the lock for any purpose. When the bolt is. moved to its unlocked position, its spring 50 will be placed under tension, and if the bolt were released immediately after the outward movement without changing its position, the spring would immediately return it to the locking position. But if it is desired, as it will be in order to operate the machine to maintain the bolt in the unlocked position, the sleeve 48 is given a quarter rotation, whereby the inner extremities of the tongues 53 are caused to enter recesses 82 formed in the abutting edges of the collars 99, .portions 83 of these recesses being formed in each collar. These recesses 82 are comparatively shallow since they only have a depth equal to the thickness of the peripheral portions of the collars 99 and in the absence of any provision to prevent such an occurrence,it would be easy for the sleeve 48 to be displaced or given a partial rotary movement sufiicient to cause its tongues to move into alinement with the recesses 62 of the collars, thus allowing the bolt to move into locking position and lock the steering post against movement. This of course, would be a serious condition and would undoubtedly result in accident. Provision is therefore made for preventing the vaccidental rotary movement of the sleeve 48 when the bolt is in the unlocked position, this provision consisting of a band 84 (see Fig." 21) which is-applied tothe collars 99 exteriorly and provided with openings 85 and 86. The opening 86 is of the same width throughout its length and closely engages the inner part oi? the bolt on opposite sidesn The opening 85 is composed of two parts 87and 88. The part 87 is of thesame width as the entire opening 86 and closely engages the reduced part of shank 41 of thebolt below the sleeve 438. This brings the adjacent portions 89 of the band on opposite sides-of the part 87 ot' the slot directly beneath the shoulders 90 formed by the sleeve %8 of the bolt. In this event, the edges of the ring orband adjacent the part 87 of the opening will be arranged on opposite sides of the tongues of the bolt so that it will be impossible to turn the sleeve into'position to allow its tongues 53 to enter the recesses 82 of the collars 99, since these recesses are closed or covered by the parts 89 of the band or ring 8%. When, however, it is desired to return the bolt to the locking position, the band is moved in a direction to cause the part 88 of the opening 85 which is as large in diameter as the sleeve t8 of the bolt, to assume a position surrounding the bolt. When the band or ring is in this position, the sleeve 48 may be turned on the bolt to bring its tongues 53- into alinement with the recesses 82 of the collars 99, in which event, the bolt may assume the locking position, as will be readily understood.

From this it will be plain that the sleeve 48 is freely rotatable on the body or shank 4C1 of the bolt. This shank member, however, has no rotary movement, since it is connected to the pallet members by the pin 46, as heretofore explained, and as these members are disposed longitudinally of the spindle and within the same, the shank of the bolt is of course, locked against any rotary action.

\Vhen the device is in use, as soon as the chau'fleur or other person in charge, stops the machine, it he desires to lock it, he will adjust the band 84; to bring the enlarged portion 88 of its opening 85 into position surrounding the bolt. The sleeve 48 will then be given a quarter rotation as just explained, whereby the tongues 53 will be brought into position to enter the recesses 62, in which event, the bolt may move inwardly into engagement with one of the openings 21 of the perforated zone of the bushing 20 of the steering post. It will be understood that if an opening 21 is not in alinement with the bolt, only slight manipulation of the post will be necessary in order to bring one of these openings into such position. As soon as this is done, one or more of the tumblers are moved in the one direction or the other, in order to throw the slots 69 of the tumbler disks out of register or alinement with the bolt to the unlocking position until he has.

adjusted the tumblers to'bring all the disk slots 69 into alinement or register with each other and also into alinement or register with the slots 540i the spindle and the corresponding slots 95 or the spools, andthis can only be accomplished by the person knowing. the combination. This can be easily done by such person, however, since when he returns and desires to unlock the machine, he will simply first moveall the tumblers toward the right as far-asthey will go or until the tongues'Zl of the shell members 59 engage the stops 77 of the spools. Then, if the disks, forinstance, from the bottomto the top of the lock are so'set that their numerals 3, l, 6 and 8 respectively, of the tumbler disks 56 are: opposite the recesses 72 which arein engagement with the tongues 71 of the tumblerv members 59,the lowermost tumbler will be moved two clicks toward the left, the next higher tumbler four clicks toward the left; the tumbler next above six clicks toward the left; and: the uppermost tumbler eight clicks toward the left, in which event, the'slots 69 ofthe disks of all the tumblers will be brought into alinement with each other and into register with the slot-5st of the spindle and the slots 95 of the spools, allowing the pallet members to move laterally as the bolt is pulled outwardly, the movement permitted being sufficient to disengage the inner extremity of "the bolt from its opening or perforation 21 of the bushing 20 of the steering post. 48 of the bolt will then be given-a quarter rotation to bring its tongues 58 into position to enter the recesses 82 ofthe collars99, after which the band or ring 84 will be shifted-to move its relatively large portion 88 away from the bolt and bring the ,relatively narrow part 87 into thebolt position, thusmaking it impracticable to turn the sleeve-48 of theboltsufliciently to permit the-return of the bolt to the locking position, except by design. 1

Having thus described my invention, what I claim is 1. A lock of the class'described comprising a casing, a hollow spindle, a laterally movable pallet in said spindle which is slotted to permit the pallet to protrude, the spindle having a centrally located opening formed therethrough atright angles to its axis, a bolt passing through said opening and to which said pallet is secured, and tumblers rotatably mounted on the spindle for controlling the'movement of the pallet through the slot in-the spindle.
