3 UNITED STATES PATENT OFFICE. ELLSWORTH E, QUAINTANCE, OF DENVER, COLORADo. PERMIUTATION-LOCK. 1,027,564. Specification of Letters Patent, Patented May 28, Application filed August 22, Serial No. 6,428. To all whom it may concern: Be it known that I, ELLsworTH. E. QUAIN TANCE, a citizen of the United States, resid ing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Permuta tion-locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification. My invention relates to improvements in permutation locks of the class set forth in my previous application, Serial Number 600,839, filed January 4, 1911, and also of the class set forth in a series of previous patents to which the attention of the office is called. In my present form of construction, the lock is equipped with a hollow spindle, to one extremity of which is pivotally con nected a shackle of the padlock type, the opposite extremity of the shackle being adapted to enter the other end of the spin dle where it is arranged to interlock with a pallet or longitudinally-disposed plate lo cated within the hollow spindle, the latter being slotted to allow the edge of the plate to pass through and enter recesses formed in parts of the respective tumbler members when the latter have been adjusted to bring the recesses into allinement, whereby the combination of the lock is solved. When the pallet or longitudinally-disposed plate is allowed to enter the alined recesses of the said parts of all of the tumblers, the extrem ity of the pallet, which is adapted to inter lock the adjacent extremity of the shackle, becomes disengaged from the shackle, al lowing the latter to be turned on its pivot for the purpose of releasing the staple or other device through which the shackle is passed for locking purposes. In this re spect, the features of the lock are common to several other patents already obtained by me for permutation locks. My present construction contains several novel features, one of which is that the ex terior surface of the tumblers is devoid of numbers or other characters adapted to be brought into alinement to indicate that the recesses of the tumbler parts are in alined relation for unlocking purposes. In my present device, the said numbers are placed upon disks carried by the tumblers and ex posed only when the lock is taken apart to set the combination, the said numbered disks being at all other times entirely concealed. Provision is made for an adjustment of the tumblers, whereby, when each tumbler is turned the necessary degree to bring the re cess of its disk into line with the edge of the pallet, a certain number of clicks may be counted by the person solving the combina tion, the said number indicating one figure of the combination when the latter is solved. In this way, each tumbler is first moved to its limit of movementin one direction, which may be termed rearwardly, provision being made for stopping the rearward movement of the tumbler at the zero mark of the num bered disk of each tumbler. In setting the combination, the figure which is to form an element of the combination is placed di rectly in alinement with an interiorly pro jecting tongue formed on the shell of the tumbler and which, when the tumbler is moved rearwardly preparatory to its for Ward movement for the purpose of solving the combination, comes into engagement with a stop on a spacing device interposed between the tumblers and carrying a spring pressed click consisting of a ball adapted to enter recesses formed in an additional disk located adjacent to the numbered disk of the tumbler. The numbered disk has but a single recess, while the disk which engages the click ball of the spacing device contains a series of recesses, one only of which is in register with the recess of the numbered disk. As the tumbler is turned, the click ball engages the various recesses of the plu rally recessed disk interposed between Zero and the number of the numbered disk form ing an element of the combination. In this way, the solver of the combination is en abled to know, without exposed numbers, when each tumbler has been moved far enough to solve the combination. Another feature consists in equipping the lock with an auxiliary pallet which does not This pallet is provided with teeth or pro jections formed on one of its edges which are adapted to enter the plurally recessed disk of each tumbler. - my patented lock, the main pallet is later interlock with the shackle of the device. 105 In several forms: of 110

Hence, if all of the pallet. Each pallet consists of a compara tumblers but one were adjusted to bring tively thin metal plate of a width making it their recesses into alinement for solving the practicable to conceal the pallet members combination, a person wishing to unlock the within the hollow spindle, the latter, how lock, and not knowing the combination, ever, being slotted to allow the pallet mem could, by constant pressure upon the pallet bers to pass Out of the spindle in an edge in the direction to cause it to enter the alined wise direction for the purpose of entering recesses and simultaneously turning the One the recesses of the tumbler parts when the tumbler to be adjusted, cause the pallet to tumblers are adjusted to solve the combina enter the recess of the tumbler in process of tion. This slot is designated 8 in the draw adjustment and thus easily solve the combi ing. The opposite extremities of the hollow nation. By equipping my present lock spindle are equipped with caps, designated with an auxiliary pallet having no inter 9 and 10, respectively. The end of the spin locking equipment with the shackle, I make dle, to which the cap 9 is applied, is pro provision for moving the auxiliary pallet vided with a pivot 12 which retains the ex independently of the main pallet when pres tremity 13 of the shackle in place, the said sure is applied to the exteriorly protruding extremity turning freely on its pivot, the device, whereby the auxiliary palet may be adjacent extremity of the spindle having a moved to cause projections or teeth formed slot 14 and the cap 9 a registering slot 15 thereon to enter the recesses of the plurally for the entrance of the pivoted end of the recessed part of each tumbler member, shackle. This pivot has both of its extremi whereby the tumblers will all be locked ties in engagement with the hollow spindle against rotary movement, if lateral pressure and the cap 9, so that, when the pivot mem is applied during an attempt to solve the ber is in place, the cap 9 is fixed upon the combination. This feature makes it impos spindle. The opposite end of the spindle is sible to apply pressure to the pallet during provided with a slot 16 and the cap 10 with the rotation of a tumbler. a registering slot 17 to receive the end 18 Having briefly outlined my improved of the shackle, this shackle extremity being construction, I will proceed to describe the recessed, as shown at 19, to receive the ex same in detail, reference being made to the tremity 20 of the main shackle 6, whereby, accompanying drawing, in which is illus when the tumblers are in the locked posi trated an embodiment thereof. tion, the shackle is in interlocking relation In this drawing: Figure 1 is an eleva with the pallet, thus preventing the opening tion of my improved lock, the shackle being of the shackle until the tumblers are so ad shown in locked position.

As illustrated in the drawing, the lock is interposed between the two centrally located provided with four tumblers, each of which tumblers of the lock. Fig. 6 is a section, may be designated in its entirety by the similar to Fig. 2, the pallet, however, being numeral 21. Each of these tumblers is cup in the unlocked position or in the position shaped and has an interiorly-projecting to allow the shackle to open.

This shell contains an interiorly-projecting I

5 tongue or rib 26, extending in a direction parallel with the axis of the hollow spindle, and, when the combination is set, the figure or character of the numbered disk 24, which 5 is placed in radial alinement with the tongue 26, forms an element of the combina tion. The disk 24 is provided on its outer edge with a series of grooves 27 located re spectively in radial alinement with the char 10 acters from zero to 10, inclusive. Each of these grooves is adapted to receive the tongue 26 when the disk 24 is inserted in the cup-shaped shell of the tumbler. After placing the numbered disk 24 in position 15 against the flange 22 of the tumbler shell, a second disk 28 is inserted. Each disk 28 has a series of radially arranged recesses 29 " spaced to harmonize with the spacing of the characters on the disk 24. This disk 28 is 20 also provided with a groove 30 on its outer edge, adapted to receive the tongue 26 of the tumbler shell, the recess 30 being so ar ranged that, when the tongue 26 is in en gagement therewith, one of the recesses 29 of the series will be in register with the single recess 31 of the disk 24. Hence, when the three elements of each tumbler 21 are in assembled relation, one of the recesses 23 of - the flange 22 of the disk shell and one of 30 the recesses 29 of the disk 28 will be in register with the single radial recess 31 of the numbered disk 24. This is true, regard less of the arrangement of the disk 24 within the tumbler, shell. Hence, when all of the tumblers are properly adjusted, the three alined recesses of each tumbler will be in alinement or register with each other, and so arranged as to receive the edges of the two pallet members as the latter are moved 40 laterally whereby they are caused to pro trude through the slot 8 of the hollow spin dle As illustrated in the drawing, there are two pairs of tumblers 21, so arranged that the open extremities of the cup-shaped shells are contiguous or arranged toward each other, each pair of tumblers being spaced by a spool-shaped spacing member 32, which is provided with an interiorly-projecting 50 tongue 33, adapted to enter a longitudinally disposed counterpart groove 34 formed ex teriorly in the hollow spindle, whereby the spacing member is locked against rotation upon the spindle. This spacing member is 55 slotted, as shown at, to receive the pallet members after the latter are adjusted to un lock the shackle after the solving of the com bination. Each of these spacing members 32 is equipped with a casing 36 having open 60 extremities 37 through which click balls 38 protrude, the said balls, being normally forced outwardly by a spiral spring 39 in terposed between them andlocked within the casing 36, the axis of the spring being paral 65 lel with the axis of the hollow spindle. Each 1,027,564 of these click balls 38 is adapted to enter the respective recesses 29 of each disk mem ber 28 every time the tumbler is turned a distance equal to the space between two of the radial recesses 29 of the said disk. It is by virtue of the action of these click balls upon the disk 28 of each tumbler that the adjustment of the latter may be accurately made for the purpose of Solving the combi nation by one who knows the elements or figures of the combination. The spacing members 32 are made of such Width that the two tumblers between which they are interposed will not rub against each other sufficiently to cause one tumbler to operate the other, while either is being ro tated on the hollow spindle; at the same time, the adjacent edges of each pair of tumblers are sufficiently close that there is no appreciable space between them. The flanged extremities of the innermost two tumblers, however, are separated by a disk 40, which is provided with an interiorly projecting tongue 41 adapted to enter the groove 34 of the hollow spindle. This disk 40 is also provided with a recess 42 which is arranged to register with the slot 8 of the hollow spindle, and, consequently, adapted to receive the protruding edges of the pallet members 6 and 7 when the latter are ac tuated to disengage the member 6 from the shackle of the lock. This separating disk 40 prevents either of the innermost two tum blers from interfering with the other during the rotary independent action necessary for solving the combination.. As the construction of each tumbler mem ber is identical with every other tumbler member, the description and arrangement of the various elements of one tumbler is suffi 1.05 cient for all. The arrangement of the two pairs of tumbler members, as heretofore ex plained, brings the flanged ends of the in nermost two tumbler members adjacent each other and in engagement with the spacing 10 disk 40 heretofore explained, while there is a spool-shaped spacing member between the individual tumbler members of each pair, the spacing member entering the open extremity of the cup-shaped shell of each tumbler mem 5. ber, half of each spacing member being located in each shell, whereby the click balls 38 of each spacing member are brought into operative engagement with the recesses 29 of each tumbler disk 28. In order that the 120 pallet members 6 and 7 may be moved later ally for the purpose of disengaging the re cessed extremity 20 of the pallet 6 from the recess 19 of the shackle 18, when the combi nation is solved, each pallet member has a T shaped extremity, that of the pallet member 6 being designated 43 and that of the mem ber 7 as 44.. The projections and 46 of the two pallet members are of the same length, while the

6 ,027,564 projection 47 of the member 6 is somewhat shorter than the corresponding projection 48 of the member 7. Hence, the part 48 of the member 7 normally extends slightly below the projection 47 of the main member 6. The T-shaped extremities 43 and 44 of the two pallet members enter a slot 49 formed in a relatively narrow plate 50, which is passed transversely through the hollow spindle adjacent the inner extremity of the cap 9 thereof, the said plate entering a cavity 51 formed by the flange 52 of a ring 53, sur rounding the hollow spindle adjacent one extremity, the annular flange 52 of the said ring bearing against a circumferential flange 54 formed on the cap 9. The ring 53 and the cap 9 may be considered fixed to the hollow spindle, when the parts of the lock are assembled, and the narrow plate 50 is freely movable in registering openings 55 and 56 formed respectively in the shell of the hollow spindle and the annular flange 52 of the ring 53. This plate 50 is of sufi cient length to protrude through both open ings 56 in the annular flange 52 of the ring 53, and, when it is desired to laterally ad just the two pallet members for the purpose of unlocking the shackle, the solver of the combination presses upon the extremity 57 of the narrow plate, and, if the tumblers are properly adjusted for solving the combina tion whereby the recesses 31 of each num bered disk 24 are in alinement with each other and with the edges of the pallet mem bers, the narrow plate 50 will be permitted sufficient movement to cause both pallet members to enter the recesses 31 of the disks 24 of all the tumbler members. If, how ever, the combination has not been solved and an attempt is made by pressing upon the extremity 57 of the narrow plate for the purpose of aiding in solving the combina tion, the auxiliary tumbler member 7, by virtue of the fact that the projection 48 of its T-extremity, is slightly RE than the corresponding projection 47 of the main tumbler member, will be actuated sufficiently to cause teeth or projections 4 formed there On to enter recesses 29 of the disks 28 of the various tumbler members, whereby rotary a recess 29 is counted equal to the number forming an element of the combination for the particular tumbler in question. Attention is called to the fact that the spool shaped spacing member has two circum ferential flanges 59 formed at each extrem ity thereof, one of these flanges being in con tact with each disk 28 of the tumbler mem bers separated by the spacing device. Each of these circumferential flanges 59 is pro vided with a stop projection 58 arranged to coöperate with the tongue 26 of the adjacent tumbler member. From the foregoing description, the use and operation of my improved permutation lock will be readily understood. In assem bling the elements of the lock, each num bered disk 24 is placed in the cup-shaped element of the tumbler with the figure of the disk which is to form an element of the combination in radial alinement with the tongue 26 of the cup-shaped tumbler shell. The tumbler members are then arranged on the spindle in such a manner that the re cesses 31 of all the disks 24 are in register with the pallet members 6 and 7. These pallets may be caused to protrude through the longitudinal slot of the spindle to form a guide for the assembling of the tumblers. Care must be taken in assembling the ele ments of the lock that the spacing device 32 be interposed between the two pairs of tum bler members, and that the spacing disk 40 be interposed between the innermost two tumbler members. After the various ele ments have been applied to the hollow spindle and the cap 10 also applied, the in terlocking extremity 18 of the shackle is passed through the registering openings 16 and 17 of the cap and spindle into position to be engaged by the pallet member 6 when the latter is in its normal position concealed within the hollow spindle. The pallet is then allowed to enter the spindle into inter locking engagement with the shackle, after which the movement of one or more tum blers to bring the recess 31 of its disk 24 out of allinement with the edge of the pallet members, will throw off the combination, so to speak, and make it necessary to solve action of any tumbler member will be pre the combination before the pallet 6 can be vented. adjusted to disengage the shackle.
