LOCK.

iaroia Specification of Letters Patent.

Patented May 25, 1915.

Application filed July 29, 1912. Serial No. 712,185.

tumbler designed to lift all or a plurality of the change tumblers.

One feature of the improvement forming the subject of my invention consists in pivotally mounting the master tumbler in the lock case on an axis independent of the axis of the change tumblers so that when such master tumbler is moved, there will be no tendency of the same to move out of its normal plane of movement at right angles to its pivotal connection. The master tumbler may carry a stafi journaled in the walls of the lock case or it may be pivotally mounted on a fixed staff.

A further feature of my invention is the utilization of the master tumbler as one of the change tumblers.

These and other features of my invention will be more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a view in elevation of a lock embodying my invention; Fig. 2, is a similar view, with the top plate removed; Fig. 3, is a view showing the bolt and master tumbler; the change tumblers being removed; Fig. 4, is a sectional elevation on the line H, Fig. 2; Figs. 5 and 6, are views illustrating modified details within the scope of my invention, and Fig. 7, is a perspective view of the master tumbler. I

The common practice heretofore has been to provide a master tumbler pivoted on the same axis as the other tumblers; in some instances having a pin which carries said other tumblers, and in other instances having a sleeve carrying the other tumblers, which sleeve in turn is journaled on a fixed 1n. p My improved construction may be described as follows:

In the drawings, 1 represents the lock case having the usual cover plate 2 concealing the tumblers 3 and holding the latter in place on their bearing post 3*. A sliding bolt is indicated at 4:, operating in a usual manner; such bolt being provided at a point at the rear of its head with a fence 5 of the usual type for coaction with the tumblers for locking and releasing the bolt.

The master tumbler or lifter which I employ with my improved lock is indicated at 6, and is pivotally mounted within the lock casing. As shown in Figs. 2, 3, 4L and 7 it may be connected to a staff 7 provided with an integral collar 8 for the permanent attachment to it by any suitable means of said master tumbler, which latter, for such purpose, may be formed with a circular opening Just large enough to receive the said collar, and said collar is by preference swaged in place. When the staff 7 is employed to carry the master tumbler, it is journaled in both the wall 1 of the casing and the cover plate 2, as clearly indicated in Fig. 4, and may be placed at a point beyond the bearing post 3 upon which the change tumblers are journaled, as clearly indicated in the drawings. This master tumbler carries an arm or sweep 10 of a suflicient height to engage all or as many of the change tumblers as may be desired, depending upon the character of the master key or of the change-keys, and the said change tumblers are provided with slots 11 which may be brought into alinement with the fence 5 carried by the bolt by the sweep 10 of the master tumbler, and when in such alinement further movement of the key will cause a ward of the same or the usual key-bearing roll-back 12, which may be employed in my lock, to engage one wall of the recess 13 in the bolt and shift the latter to the unlocked position.

In manufacturing the change tumblers, the blanks are initially provided with projections 9 which may be subsequently cut away or reduced to any desired extent with reference to the position of the slots 11 in preparing said change tumblers for as- .sembly in a lock; such projections, in their various lengths, lying in the path of the sweep or arm 10 of the master tumbler and being successively engaged by the same when the master tumbler is operated to bring the slots 11 into alinement with the fence 5. In all instances the master tumbler is pivotally mounted in the lock casing but does not necessarily carry its pivot pin. Other arrangements may be provided within the scope ofmy invention. In Fig. 5, I have shown an arrangement in which themaster tumbler isprovided with a sleeve 14: whereby it may be journaled on a staff 7 riveted or otherwise fixed to the wall of the lock casing or the cover plate of the same- In this instance the sleeve is a separate element properly secured in. a suitable-manner to the master tumbler. In, Fig. 6,. the tumbler is provided with an extended bearing which may be formed by drawing a portion of the metal to form a hub1l ;,whi'ch, hub may be journaled on a fixed staff 7 carried by the lock casing or cover plate,

Other equivalent means 'I dee'm to be within the scope of my invention.

The master or lifter tumbler is preferably placed between the bank of change-key tumblers and the bolt, although it is obvious that it might be placed'at some other point or above the same, care being taken to insure the presence of the proper means in the form of a sweep of the necessary size to effect the shifting of all orasmany of the change-key tumblers as is necessary to insure the positioning of the slots of the same in line with the fence 5.

In locks of thischaracter the change-keys do not normally engage the master of lifter tumbler, which is of such a shape as to be independent of the fence when the changekey tumblers are moved to bring their slots in registry with said fence, but I'am enabled to increase the number of key changes in a lock of this type without multiplying the tumblers, by employingsaid master tumbler as a change tumbler. For this purpose the master tumbler is provided with a slot 15 for alinement with the fence 5 when moved by a ward of the key, and with, a slot 16 for alinement with said fence when moved by a master key for the purpose of moving a plurality or all of the change tumblers.

By mounting the master or lifter tumbler upon an independent pivot or, axis, there is no dangerof the same shifting or affecting the operation of the change-key tumblers, and if desired it can be removed without affecting the operation ofthe lock by an ordinary, change-key, by slippinga spacing element to equal its thickness between the change tumblers and the rear portion ofthe bolt when it has been removed.

The keys are guided by the usual slotted keys-post 17 suitably mounted in the case and journaled in the wall and cover plate of the same, which post mayv or may not have the usual roll-back 12, and the several change tumblers are provided with the usualsprings 18 tending to hold said tumblers in such position as to prevent retraction of the'bolt. When the master tumbler is employed as a change tumbler, it will be provided with a suitable spring such as indicated at 19.

While my invention has been applied and is shown in connection with a rimlock, it will be understood that its use is not limited to looks of this character, as it may be employed in connection with any form of lifter tumbler having the described function.

I claim:

1. In a master-key tumbler lock, the combination with a case body and case cover thereof, of a post fixedly secured therein, change tumblers pivotally mounted on said post, a master-tumbler independently pivoted in vsaid casing at a point fixed with relation to the pivotal support of the change tumblers, and a sweep or lifter carried by said mastlentumbl'er for engagement with said change tumblers.
