i I LOCK. p
I Application filed June-12, 1926. Serial No. 115,440.
I This invention relates to locks and more i particularly relates to looks of the type- 'which are customarily used in 'connect1on 'with safety deposit lock? boxes, and to an 5 anti-pick device adapted to be associated with locks of thls character.
' One favorite type of locks for, safety deposit lock boxes is provided with an aperand Fig. 8 is a perspective view of the antipickdevice. f. I a a I 1 Similar reference characters refer to simi lar' parts throughout" the several views a of v the drawings. 7,
device embodying my-invention has be 'f v applied; Fig. 2'is aside view thereof, partly "broken away and partly shown inlsection;
persons to align the tumblers with the lockture in the cover plate, which is in align inent with a stump carried by the bolt bar, the ends of the tumblers of the lock being adjacent to this stump.- When, the lock is vdismounted from the door of the safety deposit box, the aperture referred to gives access to the-tumblers, by means of an in strument or tool, and permits the tumblers being aligned in this way with the stump,
' so that the bolt bar may be retracted;
This gives an opportunity to an unauthorized person to tamper'with the lock in such a way that it will not give protection to the extent desired.
The principal object of my invention is j "to provide a lock' of the character described, which frustrates attempts by unauthorized ing stump, by, manipulation through the aperture in the cover plate at the top of the stump, and thus to secure added protection.
A further object of my invention is to provide a simple ancl inexpensive device adapted to be associated with locks of various types and difl'erent constructions, for
preventing access to the tumblers through. the stump aperture in the cover plate of the look. A further object of my invention is to provide a device of the character described, which may be applied to locks of various types and different con structions, without requiring changing or altering any part of the look, but merely by adding the device thereto. Other objects of my invention will be'in part obvious and in part pointed out hereinafter.
In orderthat a clearer understanding of my invention may be had, attention is hereby directed to the accompanying draw ings,forming a part of this applicati-onand illustrating one possible embodiment of my invention.
Referring to thedrawings, Fig, atop 1 elevation of a lock, to which an anti-pick Referring to the 'drawings,the anti-pick 1 device comprises a flat'p-iece l, of metalor other suitable material," provided with an aperture 2, conforming to the siz-eandshape 7 of the transverse dimensions of the locking stump 3 'of'the lock. This plate 1 is placed. s
between thecover plate l'of the lock and the tumblers 5, With the upper'end of the lockingstump projecting through the aperture 2. The'platel islarge enough to close the aperture 6 in the cover'plateintermediate the locking stump' and lthe tumblers, during all positions, of the locking stump,
so that access can at no time'be had to the" tumblers 5 through the apertureG. Itwill be readily apparent thatfth-e'platef 1 positively prevents the pickingvof the tumblers I To'apply the anti-pick device, it is merely necessary-to remove the cover plate 4 of the lock, put the anti-pick device 1 in place, and replace the cover plate-.. 'In*the"construction' illustrated, thefi-c'over plate issee cured in place by means of afscreW 7. l a
5 through-l the aperture 6 when the lock is dismounted from a door, or-thelike.
The combination with a lock, includingf 'l housing, alocking stump movable in the housing, tumblers 1n the housing having their front ends. adjacent and recessed for the locking stump, and a cover plate having an apertureopposite the outer end of the 1 locking stump,-of a 'platefengaging the lock- 1 ing stump for movement therewith vdisposed intermediate the cover plate and the tumblers and extending across said aperture-in all positions of the locking stump, whereby access to the ends of said tumblers adjacent I the locking stump through said aperture is" prevented i June, 1926.
