PERMUTATION PADLOCK.

Application filed November 28, 1923.

To (all whom it may concern Be it known that I, ELMER E. SUTTON, a citizen of the United States, residing at Dunkirk, in the county of Jay and State of Indiana, have invented certain new and useful Improvements in Permutation Padlocks, of which the following is a specification.

Thisv invention relates to the class of permutation padlocks, and has for one of its objects to simplify and improve the construction, and increase the efficiency and utility of devices of this character.

Another object of the invention is to provide a device of this character, of few parts,

easily assembled and disassembled to change the combination or permutation, and which requires no key or external implement other than the fingers to either set it, look itin closed position, or to release the bolt or shackle.

With these and other ob ects in new the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a perspective view of the improved lock.

Figure 2 is a section on the line 22 of Figure 1.

Figure 3 is a section on the line 33 of Fig. 2, looking in the direction of the arrow.

Figure 1 is a side view of one of the set-' directed laterally from each side and with a segmental slot 12 extending into the hub and likewise through the rim of the body 10. Bearing against the opposite faces of the body disk are inner setting rings 13, while similar outer setting rings 14-. bear against the outer faces of the inner setting rings. The interiors of the several setting rings are serrated or formed with angular teeth as represented at 15 in Figure 4. Four of the setting rings are shown, two at each side of the central body 10 and are precisely alike, and are each provided with designating characters on the outer faces, for instance letters of the alphabet, as shown in Fig. 1.

Serial No. 677,443.

Fitting within each of the rings 13 and 141 is a tumbler disk, one of which is represented at 16, and each provided with teeth corresponding to and engageable with the teeth 15 of the setting rings. Each of the tumbler disks 16 is provided with a central opening 18 to rotatably engage the hubs 11, and with which the slot 19 registers when the parts are in one position. Each of the hubs 11 is provided with a longitudinal socket or seat 20 with which the segmental slot 12 communicates and with which the slots 19 of the tumblers 16 are adapted to register.

Bearing upon the outer faces of the outer setting rings 14 and the serrated disks 16 enclosed therein, are holding plates 21, each centrally apertured to register with the outer ends of the hubs 11. The interior of the hubs 11 are threaded, and engaging in these threads from oppositeends are headed clamp bolts 22, the latter operating through the openings in the holding plates with their heads bearing against the outer faces of the plates, as shown in Figs. 1 and 2.

The clamp bolts are each provided with a longitudinally directed seat 23 registering with the slot 20 of the hubs 11 and with the several segmental slots 12 and 19.

The shackle portion of the improved lock comprises an outer loop portion 2 1, a relatively long curved leg 25 and a shorter curved leg 26, the latter designed to be seated at its free end in a socket 27 in the body disk 10. The curvature of the portion 21 corresponds to the curvature of the several segmental slots 12 and 19, and extending laterally from the inner end of the portion 24 of the shackle are lugs 28 adapted to be seated in the slots 23 in the clamp screws 22 and slidable in the slots 20 of the hubs and in the segmental slots 19 of the tumbler members 16.

By this arrangement if all of the setting rings 13 and 141 and the tumbler disks 16 coupled therewith by the angular teeth 1517, be rotated to bring the several segmental slots 12 and 19,-the channel 20 in the hubs 11, and the seats 23 in the clamp bolts 22, in registration, the projections or lugs 28 of the shackle may be moved outwardly Within the range of the segmental slots, to release the shorter leg 26 of the shackle from its socket 27, and dispose the shackle in position to be engaged with a staple rod, or the like.

The shackle is then returned to its inner disks 16, as will be obvious, and the range of the diflerent Combinations may be greatly enlarged by employing the numerous interen aging teeth 15 and 17.

V he lugs 28 being engaged in the seats 23 of the clamp screws 22, looks the latter from rotation, and thus efi'ectually preventing the disassembling of the lock unless the shackle be released by setting the combination in shackle releasing position.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications Within the scope of the claimed invention may be made in t-he const-ruction Without departing from the principle of the invention or sacrificing any, of its advantages.

laving thus described the invention,

what is claimed as new is:

In a permutation ad look, a body disk having a segmental s 0t leading through its periphery and a tubular internally threaded hub with a longitudinally directed slot coinniunicating with the segmental slot, a pinrality of setting rings superposed and each with a plurality oi internal teeth, a tumbler disk within each setting ring and provided with marginal teeth engageable with the teeth of the ring and a central opening to rotatably engage the hubs of the body and a segmental slotregisterin with the opening, bearing disks external y of the setting rings and centrally apertured, headed clamp screws operating through the apertures of the bearing disks and engaging the threaded hubs, said clamp screws having sockets reg isterable with the hub slots, and a shackle device comprising an outer loop and spaced leg portions of unequal length, a part of the longer leg portion being curved to correspond to the curvature of the segmental slot of the body disk and formed with lateral lugs to engage in the seats of the clamp screws and the slot of the hub and to movably engage in the segmental slots of the tumbler disks.

In testimony whereof, I affix my signature hereto.

ELMER- E. SUTTON.
