LOCKING DEVICE.

Original application led .Tune 30, 1921 Serial No. 481,474. Divided and this application filed April 3,

1923. Serial No. 629,589.

To all whom it may concern.'

Be it known that we, GUsTAvn M. GonnsMr'rH and CARL P. BAn'rELs, citizens of the United States, residing at Hamilton, Butler County, Ohio, have invented certain new and useful Improvements in Locking Devices, of which the following is a specification.

The present invention relates to locking devices and more particularly relates' to a lock which is particularly well suited for application to safety deposit boxes, although the lock is in no wise limited in its application to lock boxes and is suited for broad application. Many locks are so arranged and so mounted that it is possible to strip them from the door or other member upon which they are mounted by pounding inwardly upon the key tube from the outside, and when the lock is so removed, its bolt will, in consequence, be removed from its locking position in its socket, and the door may then be opened without further interference from the bolt or lock. It is one of the objects of our invention to provide a lock having one or more bolts so arranged that when the main part of thelock. is stripped from the door or other element upon which it is mounted, so as to fall therefrom, the bolt bars or parts thereof 'will nevertheless be maintained in locking position in their sockets and will prevent the door from being opened. In other words, our invention comprises the provision of a lock so constructed and arranged that when mounted ina boX and locked access may not be had to the interior of a box as a result of stripping thev mainA portion ofthe lock therefrom. A further object of our invention is to provide a bolt so arranged and constructed thatV when the main part of the lock is stripped from the door vor other element uponl which it is mounted, the-bolt or a part thereof will not only be maintained in locking position in its sockets, but will also move automatically into a position which makes it `diflicult to tamper with the bolt by means of a Wire or instrument inserted through the hole provided in Jtthe door for the key seat of the lock. Other objects will be in part obvious and in part pointed out hereinafter.

In accordance with our invention we provide a lock having a slidable bolt. The'bolt is normally adapted to be slid into or out of locking position in the usual manner by operating a key, but differs from the usual one-piece bolt construction in that the bar consists of two pieces, arranged end to end,

and is so connected that normally the bolt may be slid back and forth by operating the key, but, when the main part of the llock is moved inwardly of a door or other element on which it is mounted, the two parts v of the bolt will separate, and the outer part of the bolt which is in its socket will remain therein and still function and keep the desired elements locked together. The outer portion of the bolt is preferably provided with a slot through which is mounted a bolt or screw engaging the door or other element on which the lock is mounted, the screw having'a head larger than the width of the slot,

thus permitting the desired sliding move-.

ment of the bolt into locked or unlocked position and also cooperating to maintain the bolt in locking position should the main part of the lock be removed. 'The connection between the two parts of the bolt may comprise a pin carried at one end on one of the parts at one end and adapted to engage with-fy in a perforation in the other part at its adj acent end. These abutting ends may be properly rabbeted The outer end of the bolt, when the main part of the lock is removed, may be arranged to swing about the bolt or screw extending through the slot therein so as to engage suitable stops, which will aid in maintaining that part of the bolt in locking position. The said construction is disclosed and claimed broadlyand specifically in an application filed by me June 30, 1921, Serial Number 481,474, of which this application is a division intended to cover an alternate specific construction wherein the bolt part is provided with a projection lor lug which is adapted to become seated in the socket whenV this part swings about the screw as a result of the severance of the two bolt parts. Obviously, our invention may be applied to many types oflocks and may be adapted to many uses. Y

In order that a clearer understanding of our invention may be had, attention is h ereby directed to the accompanying drawlngs illustrating certain embodiments ont our invention.V Referring to the drawings, Fig. 1 is a horizontal section of a lock box embodying our invention and Fig. 2 is a vertical section of a lock box taken on line 2-2 of Fig. 1. Similar reference characters designate similar parts throughout the several views oi the drawings.

In the drawings we have illustrated our improved lock as being mounted on the outer face of a drawer in a safety deposit box. The construction of the box is similar to the construction disclosed and claimed in our application tor improvements in lock box, Serial llumber472,501, tiled May 25, 1921. In said application we have described, and in the drawings submitted herewith we have illustrated, a safety deposit lock box which comprises top wall 1, bottom wall 2, side walls 3 and 4 respectively, door 5, hinged in the usual manner, as at 3, to one side 3 of the box, and a lock 7 secured to the rear of the door by means ot bolts 8. The key tubes of the lock are shown at 10 and an abutment plate 13 which is shown to comprise the front tace et a drawer in the box is shown secured to the side walls 14 and 15, and to the bottom 16 ot the drawer by spotwelding or other suitable means. To the inside wall 3 ot the box is lirmly secured a plate 20 having a rigid shoulder portion 21 adapted to abut against the rear tace of plate 13 along its edge which is near side 3 of the box. Rigid member 22, similar to member 20, is secured interiorly oiI the wall 4 of the box, and has a similar shoulder or abutment 23 adapted to abut against the rear 'tace of plate 13 along its edge which is near the wall 4. l/Vhen it is attempted to strip the lock 7 away from the door 5 by pounding upon or by applying pressure to the key tubes 10, the lock 7 will be forced against the rigid plate 13 which in turn is held against inward movement by the shoulders 21 and 23 of the side pieces 2O and 22, thusy preventing the lock 7 from being stripped from the door 5 in consequence of the poundingl In the construction so far described, when the' door oit the box is opened in the regular manner, the drawer therein is free to be pulled out. A lock 24, which embodies our present invention, is shown to be mounted on the rear tace of the plate 13 and is adapted to lock the drawer in the box, so that even after the door of the box has been opened in the regular manner, the lock which is mounted on the drawer must be operated in the regular manner before the drawer may be pulled out. Lock 24, except for its bolt, may be of any one of several usual types which slide the bolt, and may be secured to the inside of the plate 13 in any usual manner, as by means of screws 25, with its key tube 26 extending through a perforation in the plate 13. As shown, the lock 24 is of the type wherein one key operates two oppositely disposed bolts simultaneously to slide the same into and out oi' locking position. instead oit each of these bolts being in one piece, as is usual, each bolt consists of two parts, 27 and 28 respectively, placed end to end, and sever-ably connected, as by means et a pin 3() on one ot these pieces, such as piece 27, which pin is movably seated in a perforation 31 in the abutting piece 28. li desired pin 30 and perforation 31 may be provided on end portions which are reduced as at 2f). The outer severed piece 28 oi each bolt is provided with a slot 32 and a screw or bolt 33 is fastened on the plate 13 so as to extend through this slot 32, the screw 33 having a head wider than the width ot slot So long as the two pieces ot the bolts are connected together, their outer portions 3'? are moved by the ordinary operation t the key into and out ot lockingv position, one piece 28 moving into and out of locking engagement behind the shoulder 21 ot piece 2O and the oppositely disposed bolt piece 28 moving its portion 37 into and out of locking engagement behind the shoulder 23 ot the piece 22. rIhe rabbeted portions 29 of the two pieces 27 and 28 of each bolt bar, and the pin connection therebetween, is such that when the main part of the lock 24, including bolt sections 27, are moved inwardly of the plate 13, the outer pieces 28 or' the bolts will remain vmounted on plate 13, beL ing held there by screws 33. The portion of each oit the pieces 28 which is inwardly of the screw 33 is heavier than the portion on the other side of screw 33, and when it is treed from bolt section 27, piece 28 will pivot about the bolt 33. Each bolt part 28 has a projection or lug 38 which will become seated behind the shoulders 21 and 23y whenever these outer bolt portions 28 have turned about the pivots 33, as when the lock has been removed from the door and portions 28 are free of portions 27. In Fig. 2 the dotted lines indicate the second position of the projection 38 and the outer portion 28 of a bolt bar.

It will be apparent that the lockand bolting means described are such that the box or drawer or other element which is locked thereby may not be opened even though the main part of the lock is stripped from its mounting, and that the portions 28 of the bolts may be so arranged and designed that whenever the main part of the lock is displaced they will automatically move away from the key tube perforation in plate 13 and into a position where they may not be easily reached Vor tampered with to eiect their adjustment into unlocking position. The lock disclosed is not limited to use in connection with safety deposit lock boxes but may be adapted to many different uses.

Also, instead of arranging the bolts to abut behind shoulder members 2l and 23 separate sockets may be supplied for the bolts.
