SPECIFICATION forming part of Letters Patent No. 635,783, dated October 31, 1899. Application filed August 4, 1 899. Serial No. 726,156. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM B. KELSEY, of
Stamford, in the county of Fairfield and State of Connecticut,have invented certain new and useful Improvementsin Locks; and I do hereby declare the following to beafull, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in looks; and it consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.
In the accompanying drawings, Figure l is a View in elevation, taken from the cylinder side of the lock. Fig. 2 is a similar View, partly in section, the cylinder and cylindercasing being removed. Fig. 3 is a view in transverse section, taken through the cylinder; and Fig. 4 is a view similar to Fig. 2 of a modified form of look.
A represents the face-plate, having a flange a at its outer end, with a rectangular opening therein for the passage of the locking-bolt B. The plate A is provided at its four corners with screw-holes for the attachment of the lock to a door, drawer, or other article and is provided near its rear edge with a pin 19, on which a plurality of tumblers C are mounted. These tumblers are each provided with the usual key-bearing surfaces on the side adjacent to the key and are provided on their opposite side edges each with a projection a, which engages or abuts against a toe d on the end of a dog D. In the present instance I have shown four tumblers and four dogs; but I would have it understood that I do not confine myself to the use of any particular number. The dogs D are pivotally mounted on a pin 6, carried by the lockingbolt, and each dog carries a spring f, the springs of the several dogs all resting against stud g. Secured to the face of the bolt B and running lengthwise the same is the guardplate 7L, which latter is provided with a slot 1,
through and beyond which the toes of the series of dogs project, the springs f holding the dogs normallyin contact with the guard-plate 70, with their toes projecting through the slot and beyond the guard-plate. Secured to the face-plate of the lock and projectinginwardly through an elongated slot m in the bolt is the locking-plate E. This'locking-plate is provided with a slot n, which when the bolt is in its locked position is coincident With the slot 2 in the guard-plate, thus permitting the toes on the dogs to pass into said slot in the locking-plate. Hence it will be seen that when the bolt is in its locked position it is necessary to first move the toes of the several dogs D out of the slot in the locking-plate E before the bolt can be withdrawn. This is accomplished by the projections c on the tun1- blers engaging the toes d and moving them rearwardly until all of the toes have passed without the slot in the locking-plate. The toes of the dogs are preferably of unequal lengths, and the corresponding projections on the tumblers are also of unequal lengths, and as the locking-plate restsin close contact with the guard-plate and as the guard-plate is secured to the sliding bolt and the locking-plate to the face-plate of the lock it will be seen that in order to release the bolt it is necessary to move all the dogs a sufficient distance, so as to bring the free ends of the toes in a plane passing between the guard-plate and the lockingplate. This is essential with this form of look, as it will be seen that if the toes of the dogs were moved to one side of the plane above described the projections on the tumblers would enter the slot in the guard-plate and prevent the bolt from sliding longitudinally. With this construction of lock it will be seen that the tumblers must be made to move a distance just sufficient to carry the toes of the dogs clear of the locking-plate and be held in such position until. the bolt has been started inwardly. This is accomplished by the key F having steps or bittings 0, each of which moves its respective tumbler a sufficient distance to carry the toes of the dogs out of the slot in the locking-plate and into a plane passing between the guard-plate and the lockingplate. The lower end of the key F, below the bittings o, is constructed to enter the slot p in the bolt and engage the latter, so as to move it inwardly after the dogs have been released from the locking-plate. As the bolt begins to move the toes d of the dogs D move from off the projections c on the tumblers and slide in contact with the face of the lock ing-plate E. Hence when the bolt is again thrown to its locked position the toes of the and covers and conceals the locking mechanism.
In the construction shown in Fig. LI have dispensed with the guard-plate on the bolt and employ in lieu thereof an abutment 11, secured to the faceplate of the lock and 7 adapted to engage projecting tailpieces w on the dogs in the event the free ends of the toes of the latter should be thrown beyond the plane of the adjacent surface of the locking-plate. This abutment is located parallel with the locking-plate and is a sufficient distance therefrom to allow the dogs carried by the .bolt to move freely between them; but should any one of the dogs be moved a trifle too far it would engage the abutment and prevent the bolt being retracted.
It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention, and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described; but,
Having fully described my invention, what I claim as new, and desire to secn re by Letters Patent, is-
1. In a lock, the combination of a case, a bolt and a locking-plate with pivoted tumblers connected to the case and actuated by the key, and movable dogs which normally engage with the locking-plate until set by the tumblers.
2. In a lock, the combination of pivoted key-actuating tumblers and movable dogs and a locking-plate, said tumblers and dogs .being provided with coincident bearing-surfaces, so that when the tumblers are set by the proper key, the dogs are released so that the bolt may be withdrawn.
3. In a lock, the combination with a casing, a bolt, spring-actuated dogs carried by the bolt and having projecting toes and tumblers carried by the lock-casing and having projections coincident with the toes on the dogs, of an interposed locking-plate forming an abutment for the toes of the dog when the bolt is in its locked position.
4. In a lock, the combination with a casing, a bolt, spring-actuated dogs carried by the bolt, each dog being provided with a toe and tumblers carried by the lock casing, each tumbler having a projection corresponding in position to the toe on the dog, of an interposed locking-plate forming an abutment for the dogs when the bolt is in its locked position and means for preventing the bolt from being withdrawn when the free ends of the toes of the dogs are moved beyond the plane of the adjacent face of the locking-plate.
5. In a lock, the combination with a casing, a sliding bolt, spring-actuated dogs carried by the bolt and provided with toes and tumblers carried by the casing and provided with projections coincident with the toes of the dogs, of a guard-plate and a locking-plate interposed between the dogs and the tumblers, the guard-plate being carried by the bolt the locking-plate by the casing, the guard-plate being provided with a slot for the toes of the dogs whereby the said toes engage and rest against a shoulder on the locking-plate whe the bolt is in its locked position. I
(5. In a lock, the combination with a casing, a sliding bolt, spring-actuated dogs carried by the bolt, each dog being provided with a projecting toe and a series of tumblers carried by the casing, each tumbler having a projection coincident with the too of its respective dog, of a slotted guard-plate and a slotted locking-plate located intermediate the dogs and tumblers, substantially as and for the purpose set forth. I
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
WILLIAM B. KELSEY.
