To all whom it may concern;

Be it known that I, WARREN IkTAYLon,

of Stamford, in vthe county of Fairfield and. State of Connecticut, have invented certain new and useful Improvements in Means for Securing Looks to Doors; and I do hereby declare the followin to be afull, clear, and exact description 0 the invention, such as will-enable others skilled in the art to which it liadppertains to make and use the same;

y invention relates to'an improvement in means for securing locks to doors and par ticularly to the doors of safe deposit boxes. It is customary, when a safe deposit box is surrendered by the renter thereof, for the custodian of the boxes to replace the lock witha lock having a difierent combination, for. preventing the box from being opened by a key used with the old or former lock.

Heretofore locks have been secured to the doors. of'the boxes by means of screws passing through the lock case and into the door,

and one of the difficulties experienced by the safe deposit companies in removing a lock and replacing it with another, is the fact that the locks which. were applied by the safe maker at the time the boxes were erected, were more or less adjusted each to its individual door, hence it frequently happens.

that the .screw holes in the lock cases do not perfectly aline with the holes in the door, so that in screwing the lock down tight the screws will draw the nose or key cylinder of the lock to one side and thus bind or strain thekey hub or the lock bolt and prevent or impair the operation of the lock.

The object of this invention is to provide ,means whereby the locks may be readily,

easily and quickly exchanged without the employment of screws or other fastenin devices passing through the-lock case,'an my invention consists inthe' parts and combinat-ions of parts as will be more fully described .and pointed out in theclaims.

- In the accompanying drawings, Figure 1 .is a view in elevation ofthe rear face of a door showingthe lock secured thereto. Fig. 2 is aview 1n side'elevation, part of the door being broken away. Fig. 3 is a view in end elevation. liigs. 4, 5 and 6 are similar views of a modified form and Figs. 7 and 8 are views of another modification.

1 represents the door of a safe deposit box or other receptacle provided with a cylindrical hole through same for the passage of consequently conceals the door is thick, so that when the lock 3 is applied to the rear faceof'the door, the front end of the nose orliey cylinder will be approximately flush with the outer surface of the door. v I

Thedoor is provided on its rear face, near its outer free edge with a grooved adapted to receive one end of the steel or other metal strap 5. This strap is preferably as'wide as the lock case, and is bent at its two ends to overlap and snugly fit the front and rear ends of the lock case. The bent front end 6 of this strap 5 is slotted as at 7 for the passage of' the bolt 8 of the lock 3, and the portion thereof within the groove 4; in the rear face of the door, is provided with a screw hole for the passage ofthe screw 9, which is passed through the ed e of the door, and is 5 when the door is closed. The rear bent'end 1Q of strap 5. is

bent at ri 'ht angles as at 11 to rest against the rear face ofthe door and is provided with a screw hole for the passage of a screw 12 into the door, the hole in the end 11 of the strap being sufliciently large topermit the screw to be screwed Home without-imparting any lateral strains to the strap."

The strap is preferably so constructed that some pressure is required to seat the. end 11 thereof against the door, hence when secured, it closely and snugly embraces the .lock with a yielding pressure and holds the same solidly in 'position, the bolt, and nose or key cylinder of' the lock, preventing any lateral movement-in the pocket formed by the strap. The front end of the lock 'is preferably provided with a notch 13 and the strap'with a rib 14, adapted to register with said notch for centering or properly alining the lock.

To apply the look too door, the strap is first placed-in pom'tion over the lock, with the bolt 8 projecting through the slot 7 in the front bent end 6 of the strap 5, after which the nose or key cylinder 2 is inserted in the hole in the door, and the lock with the strap therein, then pushed or forced against the door. The hole in the door and the nose or cylinder of the lock, locate thelatter definitely without any pressure whatsoever except directly toward the door. This inward movmncnt of the lock and strap, carries the bent end 6 of the latter into the groove in the rear face of the door and it is secured V therein by the screw 9. After the strap has been secured at its front end, its rear .bent

end 11 is forced into contact with the rear face of the demand secured by the screw 12.

To remove a lock the screw '12 is first re moved, then screw 9, which releases the lock and strap and permits the lock to be detached from the strap.

In the construction shown in Figs. 4, 5 and 6, I have provided the inner face of the door with an undercut roove 15 and the front end of the strap with-an inclined lip 16 adapted to engage the inclined wall of the undercut groove, and be retained in contact therewith without the aid of a screw, and in Figs. 7 and 8 I have provided grooved lugs 17 projecting from the inner face of. the

door, which are engagedby outwardly prothe passa e of the lock bolt, and means for securing e two ends of the strap tothe rear face of 2. The combination with a door having a hole through same and a lock having :a nose or key cylinder adapted to rest in said hole, of a stra embracing the rear face and two ends of the lock and secured at-both ends to the rear face of the door.

3. The combination with a door having a groove in .rear face and a hole extending through the door and a lock having a nose or key cylinder adaptedto rest in said hole, a

of a strap embracing the two ends and rear face of the lock, the front'end of saidstrap resting in the screw securing t e rear end ofsaid strap to the door.

5; The combination with a door having a groove in its rear face, and a hole extending through the door,-and a lock having a nose or key cylinder resting in said hole, of? an elastic strap embracin rear'face of the lock, t e front .end of said strap being secured within the groove in the door by a screw, and means securing the rear end of the strap to the door.

. In testimony whereof, -I have signed'thi specification 1n the presence of two subscribing witnesses,
