Application filed. December 8, 1913. serial No. 605,454.

To all whom it may concern Be it known that T, HAROLD C. SHIPMAN, a subject of the King of Great Britain, and resident of the city of Ottawa, Province of ()ntario, Canada, have invented certain new and useful Improvements in Keyless Locking Devices, of which the following is a specification.

The invention relates to improvements in keyless locking devices, as described in the present specification, and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel arrangement and construction of parts moved and portions therebeneath brokenaway. Fig. 2 is a crosssectional view on the line 22 of Fig. 1. Fig. 3 is a perspective .detail view of one of the ring-members.

Fig. t is a perspective detail view of the pair of the disk-members. Fig. 5 is a perspective detail view of one of the buttons. Fig. 6 is a perspective detail view of one of l the spring retaining washers of the diskmember and the spring therefor. Fig. 7 is a perspective detail view of one of the spring-washers. Fig. 8 is a perspective detail view, showing the locking device attached to a trunk or the like. Fig. 9 is a perspective detail view, showing the looking device attached to a mail-bag or the like.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, Figs. 1-7 illustrate one embodiment of my invention adapted to a padlock formed from stamped parts asbeing preferable for cheap construction, though it must be understand that:

the number of parts as hereinafter described are notOf necessity separate, and in many instances are riveted one to the other to form substantially an integral piece.

The casing 1 of the lock is formed substantially circular with the side-flange 2 extending therearound, said side-flange having the hinge opening 3 and the opening 4: at the top thereof for the lock-bow 5. The casing 1 further has a central orifice 6 therethrough, and a number of orifices 7 therethrough adjacent the edge and radially spaced around the casing on the lower half thereof. A cover plate 8 is secured to the side flange 2 of the casing 1, said cover-plate having the central orifice 9 and the radially spaced orifices 10 therein similar to the casing 1. The locking member, or bow 5 of the lock is hinged at one extremity on the rivet 11 inserted through suitable orifices in the casing and cover-plate immediately inside the hinge opening- 3, the latch end of said bow hooking through'the opening 4,

and having the hooked end 12. A center rivet 13 is inserted in the lock with the reduced ends 14: extending through the orifices 6 and 9, and riveted therein to retain the spring washers 15 in position. The spring washers 15 have the spring arms 16 extending radially therefrom and spaced to correspend with the radially spaced orifices 7 and 10, and are secured by the reduced ends 14: of the rivet 13, which passes through the central orifice 17 in the spring washers, and

securely fastens. them between the larger center portion of the rivet 13 and the casing 1 and plate 8.

In each of the orifices 7 and 10 in the easing and -cover respectively, buttons 17 are placed, having the ends 18 protruding outwardly through the orifices, and the corresponding ends 19 extending inwardly in the casing on each side of the collars 20, certain of said collars fitting immediately under the extremities of the spring-arms 16, whereby the ends 18 which protrude through the orifices are resiliently held to their position with the collars 20 bearing against the easing and the cover-plate on the inner sides thereof.

The inner ends 19 of the buttons extend inner side of the casing and cover respectively, said rings. having the angularly turned ends 32, which extend through suit- GOl'llIIlOIl means certain of the collars on the buttons 17 as hereinafter mentioned, and permit the said collars 20 of the buttons to move to the extent of the depth of the recesses, the ends 19 passing into the orifices 33 in the bed of said recesses. A having the central orifices 22 therethrough are rotatably mounted between'the ring seg ments 31 and on the center rivet 13, said disks being cut away at 23, and having the catches 24 formed on the top thereof to interlock with thehook 12 of the bow as hereinafter described. The disks 21' have the orifices 25 therethrough corresponding'to the orifices 33 in the ring segments, and further are spaced slightly apart by the washers 26 riveted therebetween. The washers 26 are provided with slots 27 whereby flat springs 28 having the turned ends 29 may be secured between the washers with the turned end extending into one of the slots '27, whereby the spring is held in position extending radially from the washer and midway between the disks 21. The springs 28 extend outwardly past the orifices 25 in the said disks 21, and short pins 30 are inserted through certain of the orifices 25, whereby they are spring held with the outer ends thereof extending beyond the outer faces of the disks.

The pins 30 are preferably three or four in number, and are arranged as desired about the disks with the corresponding fiat springs, and projecting either toward the back casing or cover plate of the lock, and interlocking with the segmental rings 31, that is, they project into the corresponding orifices 33 in the segmental rings, thereby preventing the locking disks from rotating.

In the closed position of the lock as shown in Fig. 1, the hooked end of the bow extends into the casing, and is caught onto the catches 24 of the disks, said disks being prevented from rotating by the interlocking pins as hereinbe'fore mentioned. The disks however have the spring 36 encircling the "center rivet 13, one arm of said spring being hooked into the lug 27 from the hinge knuckle of the bow 5, whereby a normal pair of locking-disks 21 therein.

The pins 30 as hereinbefore mentioned are preferably three or four in number, and may extend toward either the casing or cover plate of the look as desired, and into the corresponding orifices 33 in the rings to hold the lock in closed position, and it is necessary to have the end 19 of each button 17 which is opposite a pin 30 shorter by the length of the pin which projects into the orifice 33 in j the ring, so that on pressing any one of the buttons 17' which is opposite a pin 30, the button will move just far enough to bring the pin flush with the inner face of the segment ring, so that when the proper buttons are pressed about the lock, that is, each one opposite a pin, all the pins carried by the disks will be moved flush with the face of the rings, and permit the disks to be moved by the spring 36 in the direction counter clockwise, and release the hooked end of the bow, so that the same will spring open.

In the above manner the pressing of the ,proper buttons forming a known combina- It is therefore necessary that only the proper buttons be pressed, and it will be further readily understood that the buttons at all times are returned by the spring arms controllingthe same to their normal position, whether the lock is open or closed, so that it is impossible at any time to read the combination of buttons that control the locking pins.

When the lock is open the disks rotate to the extent allowed by the upturned lug 39 projecting from the ring 31 into the notch 38 on the periphery of the disk, and when it is desired to close the lock it is only necessary to spring the bow into the casing, whereby the hooked end of the bow contacts with the disks adjacent the catches thereon, and rotate the same in clockwise direction ,until the hooked end of the bow is caught under the catches on the disks, and the'locking pins have been carried by the rotation of the disks to register with the orifices 33 in the weenie rings into whichv they spring, and again hold the lock in closed position.

It must be understood that the look as hereinbefore described particularly refers to a pad-lock preferably formed of pressed sheet metal, though the said lock may be cast or formed in various ways to operate on substantially the same principle and have the same operative parts. Furthermore, the essential locking-mechanism comprising the locking diskmember and casing buttons, may be employed in connection with an ordinary spring latch-bolt, to operate the same in a manner suitable for a lock as ordinarily used on doors, or may be readily arranged to operate as a locking device on trunks, mail-bags or in fact any meeting parts to be locked together. That is to say, the essential features of the invention constitute the particular arrangement of locking-pins and depressible buttons, whereby a certain predetermined combination must be. known, in order that certain selected buttons may be pressed to release the locking-pins without having any one or more buttons interfere with the locking-member or disk, whereby the same may be released to open the lock.

Fig. 8 illustrates my invention adapted for use with a trunk, or other similar construction; a lockin member 40 being provided for ready attac ment to thetrunk lid.

Fig. 9 illustrates my invention applied to a mail bag; a locking member 41 being pivotally connected to any usual form of locking bar 452 of said bag.

I therefore do not wish to be confined in this respect to the particular arrangement or construction of parts as preferably shown and described in this present application.
