To all whom it may concern:

Be it known that I, NAUM S. G. BEsHARov, a subject of the Czar of Russia, a'n'da resident of Paterson, inthe county of Passaic and State of New Jersey, have i'nvented a new and Improved Tumbler for Combination-Locks, ofwhich the following is a full, clear, and exactdescription.

, This inventionrelates to improvements in combination locks of the type disclosed in United States Letters Patent Number 1,046,253, granted to me December 3, 1912, and the invention has to deal more particularly with improvements in the construction of the tumblers for suchcombination locks.

yThe invention has for its'general' objects to improve and simplify the construction of tumblers for combination locks so as to be more reliable and eflicient in operation and inexpensively and. expeditiously manufac-- tured and assembled. 1

,With such objects in view and .others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of claims appended hereto. j

In the accompanying 7 drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views, Figure 1 is an elevation of a lock with .portions broken awayto illustrate the tumbler mechanism and 'thebar controlled thereby that in turn controls the throwing of the bolt of the lock; Fig. 2 is a plan view of one of the tumblers, Fig. 3 isa sectional view on theline 33,"Fig. 2; FigLAriS a perspective view of the cover plate of theytumbler; Fig. 5'is a plan view of thebottom plate of the tumbler with several of the spring-actuated gates andgate catches assembled; Fig. 6 is a plan view of the bottom and intermediate plates, part of the latter plate being broken away, and Fig. 7 is a detail viewshowing one of the gates and the key recess controlled by the gate.

Referring the casing of a combination lock which contains the tumbler mechanism B for'control' ling the throwing of the bolt 2of the lock, this controlling being effected by the'tumbler mechanism B acting on a bar? which has a keye which prevents movement of the bar Sunless the various tumblers 5 are'in'a to the drawing, A designates TUMIBLER FORCOMBINATIONLOGK.

predetermined'position with certain gates in r alinement so that the key can pass into engagement successively with the alining gates to throw the same open, as will be under-- stood by reference to the patent hereinbefore referred to. On the bar 3 are stops 6 and 7 j that coiiperate with the tumblers when the bolt is in locking position'and the tumblers then shifted, whereby such stops form bar- 'riers for engaging the tumblers or their closed gates to. prevent the key-carrying bar 3 from being moved to efiect the unlocking of the bolt. These parts are of usual construction so that more detailed explanation is deemed unnecessary. x p

Each tumbler is'composed of three plates are fastened together to form means for holding the gates 11 and the gate'catches 12.

8, 9 and 10 which are of circular form and Thebottomplate 10 is fastened to an en the axle 17 on which the tumblers turn. The

endof the bushing 16 opposite from the plate 10 enters an opening 17 on the top plate 8. The intermediate plate 9 is fastened to the platelO by screws 18 and the plate 8 is fastened to the plate 9 byscrews 19. Confined between the intermediate plate 9 and bottom plate 10 are radially movable gates 11 which slide guideways formed by approximately semi-cylindrical grooves 21 in the plate 10a'nd corresponding grooves22 in thepate 9. These gates are of round cross-section and each has a lug 23 on its inner end'that engages the outer end of a radial slot 24, whereby the outer movementof a gate is limited. Between the inner endof each gate and thehub-forming bushing 16 is interposed a helical spring 25 which urges the gate outwardly, but its movement is limited by the lug 25,. Associated with each gate is a catch 12 that is slidable transversely to its associated gate, so that when the latter is pressed inwardly the catchwill spring outwardly in f ont of the gate and ho d t e same etracted, there being behind each catch 'a s rin 27. The catch 12 and coactin sprin P a e g held in place. hen the several plates are put together after the gates 11 and their springs and tne catches 12 and their springs are assembled, the teeth of the various plates register, so that a plurality of radial slots or recesses 34 are formed, each having a gate 11, and through any one of these recesses the key 4, Fig. 1, is capable of passing when the tumbler or tumblers'occupy a predetermined position. It is to be noted that the plateS is of smaller diameter than the plates 9 and 10, as thelower end of the key 4 and the stop pins 6 and 7 are adapted to lie in the same plane with the plates 8 of the respective tumblers when the bolt is in locking position, as shown in Fig. 1, these pins servingto act as bafliers to prevent the unlockingof the bolt by any one who does not know the proper combination for the tumblers.

To insure easy movement of the gate 11 inwardly when the key 4 engages the same, the side of each recess 84 opposite from that side from which the catch 12 projects, is formed with a shallow groove 34 Fig. 7, and the gate 11 bears therein so that there is no possibility of the gate binding by being canted or tilted as the key 4 engages and wipes transversely past it. To: permit the tumblers B to rotate with a minimum of friction, washers 35 are interposed between the tumblers and arranged on the axle 17 From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the'art to which the invention appertains, and while I have described the principle of operation, together with the device whichl now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as are within the scone of the appended claims. 7 7

Having thus described my invention, I claim as new and desire tosecure by Let ters Patent:

1. A tumbler-for a combination lock comprising a ring, a circular body disposed within and connected with the ring, there being an approximately circular slot between the ring and body, said body being made of a plurality of plates separably connected and provided with radial slots lying in the plane of division of the plates, sliding gates 7 tion, said body having in its periphery recesses into which the gates normally extend and through any one of which a key is adapted to pass to force'the gate open while the bolt of the lock is being thrown to locking position, the catch of the open gate being automatically released by the key during its return movement. St

2. A tumbler fora combination lock to control the operation of the bolt thereof, said tumbler comprising a body having one or more recesses through which a key is adapted to pass duringthe throwing of the 85 bolt toand from looking position, said body being made of separabl-y connected plates each having oppositely-disposed grooves forming guideways, gates slidable in the said guideways and of round; cross-section and adapted normally to close the recesses of the body, means for urging the gates outwardly, stops on the gates arranged to engage one of the plates towlimit the outward movement of the gates, and spring-pressed catches arranged in the body and adapted to be automatically projected into engagement with the gate when the latter is in open position and to be automatically released by a key passing the open gate in order to permit the gate to return to normal position when the key has passed.

3. A tumbler of the class described comprising inner and outer plates, a hub on one of the plates and extending through the other plates, said plates having their peripheries provided with registering recesses, sliding gates mounted between two of the plates to normally close the recesses, springs interposed between the gates and said hub for normally holding the gates outwardly, spring-pressed catches mounted in one of the outer plates, whereby any gate will be held in open position, there being openings in the middle plate registering with the spring-pressed catches, and projections on the other outer plate to enter the openings of the inner plate for holding the springpressed catches in place.
