lVALTER G. DENN, OF PHILADELPHIA, PENNSYLVANIA.
LOCK.
SPECIFICATION forming part of Letters Patent No.'688,070, dated December 3, 1901.
Application iiled August 19, 1901. Serial No. 72,558. (No model.)
To all whom, it' may concern:
Be it known that LWALTER G. DENN,a citi'v zen of the United States, residingin Philadelphia, Pennsylvania, have invented certain Improvements in Locks, of which the following is a specification.
The object of my invention is to construct a spring tumbler-lock of simple construction, compact form,and general application, an object which I attain as hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a back View of my improved lock. Fig. 2 is a sectional plan view of the same on the line ct a, Fig. 1, but showing the lock reversed. Fig. 3 is a transverse section on the line o b, Fig. 2. Fig. 4 is a perspective view of the tumblers and washers of the lock detached from each other, and Fig. 5 is a perspective view of part of the key of the lock.
1 represents the back plate of the lock, which has at the front a projecting cylindrical casing 2, in which is contained the cylindrical tumbler-carrier 3 of the lock, the latter containing a series of tumblers 4, separated by interposed washers 5 and held in place longitudinally in the tumbler-carrier between the closed front end 6 of the latter and a plug 7, which is inserted into the rear end of said tumbler-carrier and is held in place therein by means of a transverse pin 9 or in some other suitable way. To the enlarged head of this plug 7 is secured, by means of bolts or screws 10 or in any other convenient way, the bolt 11 of thelock, which consists of a simple arm engaging with the keeper when adjusted to one position-for instance, the position shown by full lines in Fig. l, but free from engagement with the keeper when moved to the other position, as shown by dotted lines in Fig. 1, suitable stops 12 and A13 limiting the movement of the bolt 11 in either direction, and the stop 12 also overlapping the bolt 11 on the rear side, so as to brace the same when it is in the locking position.
To a longitudinal slot 14 inthe tumblercarrier 3 is adapted a sliding dog 15, which when the bolt is in the locked position can enter a rounded or beveled recess 16 in the cylindrical projection 2 of the lock-case, that portion of the dog which enters said recess being also rounded or beveled, whereby the turning movement of the tumbler-carrier 3 in the cylinder 2 will cause the dog to be forced inwardly intol the slot 14 of said tumbler-carrier.
On the inner face of the Adog 15 is a projecting lug 17, and in the periphery of each of the tumblers 4 is formed a notch 19. Hence when all of thetiimblers have been adjusted so as to bring their notches in line beneath the rib 17 of the dog said rib can enter the notchesi'on the inward movement of the dog and rotatable movement of the tumbler-carrier will be permitted, such movement being obstructed, however, at other times.
Each of the tu mblers is normally held in the locking position shown in Fig. 3 by means of a spring 20, contained within a slot 30 formed in the tumbler, one end of this spring bearing upon one of the walls of said slot, as shown in Fig. 3, and the other end of the spring being adapted to a longitudinal slot 21 in the tumbler-carrier 3, as also shown in Fig. 3.
The periphery of each of the tumblers 4 is recessed, as shown at 22, so as to form a segmental keyway between the tumblers and the inner face of the tumbler-carrier 3, this keyway being extended through the end of the tumbler-carrier, as shown at 23 in Fig. 2.
Each of the washers 5 is prevented from rotating by means of a lug 24, which enters a longitudinal slot or groove cut in the inner face of the tumbler-carrier 3, and each washer has a peripheral recess 25 for the reception of the lug 17 of the dog 15 and also a peripheral recess 31 for the reception and play of the segmental key 26, which is bitted on the forward edge, as shown in Fig. 5, to correspond with the location of the notches in the various tumblers of the lock.
When the key is inserted in the keyway and moved therein so as to bring its bitted edge into contact with the upper end of the peripheral recess 22 of each tumbler, said tumblers will be moved so as to bring their notches in line with the lug of the dog, and thus perlnit the inward movement of the latter and the turning of the tumbler-carrier so as to open the lock. The forward movement IOO into line with the recess 16 in the cylindrical casing 2-that is to say, when the bolt 11 is again restored to locking position. springs 2O finally move the tumblers to their normal position, which is determined by contact of the lower wall of the spring-receiving slot 30 of each tumbler with that portion of the spring adjacent to the end which enters the slot 21.
A lock-of vthe character described is of simple construction and is extremely compact, owing to the fact that the tumbler-actuating springs are contained within the recesses of 'the tumblers, and hence do not increase the diameter of the tumbler-carrier. The same tumbler-carrier can, moreover, be employed in .locks of varying depth, it being only necessary to increase the thickness of the head of the plug 7to accord with tlhe depth of lock desired, so that one size of tumbler-carrier is available vfor all of the dierent sizes of locks.
Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The combination, ina lock, of the rotatable tumbler-carrier, its dog, the notched tumblers having spring-receiving slots and peripheral recesses forming a keyway, and tumbler-actuating springs contained within The l said slots, and engaging with the tumblercarrier, substantially as specified.
2. The combination in a lock, of the rotatable tumbler-carrier, its dog, the notched tnmblers recessed to form a keyway and having spring-receiving slots, and tu mbler-actuating springs contained within said slots and engaging with the tumbler carrier, said springs also serving as stops to limit the backward movement of the tumblers, substantially as specified.
3. The combination of the back plate of the lock and its projecting casing, the tumblercarrier rotatably mounted in said casing, a bolt consisting of an arm secured to said tumbler-carrier and stops on the back plate for limiting the swinging movement of said arm, substantially as specified.
4:. The combination of the back plate of the lock and its projecting casing, the tumblercarrier rotatably mounted in said casing, a bolt consisting of an arm secured to said tumbler-carrier, and stops on the back plate for limiting the swinging movement of said arm,
4one of said stops overlapping and serving as a brace for the bolt when the same is in the locking position, substantially as speciiied.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WALTER Gr. DENN.
