.LOGK FOR BANKS-AND LIKE. 5

T 0 whom it may concern: j

Be it known that I, JOHN NUTRY, residing at Ridgewood, in the county of Bergenand State of New Jersey, haveinvented certain new and useful Improvements in Looks for Banks and the like, oi' which the following is a specification. I

This invention relates to alock for banks or the like.

The object of the invention is to provide a lock which is simple, practical and efiicient for this purpose, and one which may be manufactured and assembled at'small cost. A further object is to provide a lock which may be made up wholly of sheet metalparts properly shaped and assembled.

A further object is to provide a lock such that one of the essential-elements {thereof may comprise the door ofjthe bank.

A further object is to provide a lock such that one of the essential *elementsfithereof may comprise hinge portions by Which to connectthe door ofthe bank in'position'. 7

the scope of protection contemplated will be indicated in theappended claims. 7 I In the accompanying drawings whlch are to be taken as apart of this specification, and Y in which I haveshown merely a preferred form of embodiment of the invention: Figure lis a longitudinal sectional view through a lock constructed in accordance with this invention, the same being shown in association with a bank structure.

Fig. 2 isa transverse sectional view taken substantially upon the plane of line II-II of Fig.1.

Fig. 3 is'airontelevational view of the bank door showing'features of the lock asso- Fig. 4 is-a view similar: to that shown Fig. 3 but the face plate of the lock, constle tuting the door of the 'banlg being removed so as'to disclose the-mechanism wlthin the I lock.

Fig. 5 is a view illustrating the'form of key employed.

Referring tothe drawings for describing in detail the structure which is illustrated therein, the reference character L indicates a Specification of Letters Patent. Pat t d 22, 1921 .Application filed-April 5, 1919 Serial No. 287,890.- I

bank structure. This structure is formed with an opening l therein closed by a door (1. The door G is made up of a single flat rectangular piece of sheet metal of a sizeto properly fit within the opening 1 in a posi- UNITED s'rarssra'rsn'r OFFICE. i

tion restlng against stop members 2 rigid within the bank, as graphically illustratedin Fig. 2. The door G constitutes the front I I plate of the lock. A back plate H is connected with the door, or plate G being shaped so as to provide a narrow closed compartment 3 at the rear of the plate G.

Vllithin the compartment '3 is arranged a lock member 4 anda turn plate 5. These two elements are separately formed and are the only elementswithin the compartment.

The lock member: 1 is madefrom sheet metal having a portion cut therefrom to provide a pair of arms 6 and 7 spaced apart at the opposite sides. of the member, said arms being connected together at their lower ends by a-portion of the sheet metal, as at 8,

said portion 8 being the only connection between the, arms so as thus to render the uppen ends of the arms resiliently movable toward and away from each other due tothe inherent resilience of the metal. -The arms 6 and 7 normally be w th their outer edge portions restlng. against the inner surfaces of the side walls, or flanges ,9 of the back. plate The upper end portions of the arms are bent to provide 'flanges '10 and these flangesv are extended and formed into cam shaped latch heads 11 disposed to project throughop enings 12formed'inthe flanges!) at opposite sides of the back plate.

The back plate is of just sufficient width to pass between the stop members 2 of the bank, and the latch heads 11 are adapted to cam past said stop members and tosnapbe-f hind the'stop members,"the arms 6 and 7 of 61181081; ember" 4; yielding to permit this action. I

Each of the arms'6 and 7 of the'lo'ck. member "is provided with an extension 13' projecting therefrominto position at opposite sides of a keyhole 14; so. that a key, as 15,-

ins'erted in said keyhole will be operable. uponthe opposing surfacesi lti of saidextensions to move thelatch heads toward each 'A'key thus operable will enable disother. engagement of the latch heads from behind the stop members 2' whenever desired. "Preferably the; keyhole 14 is formed partly V I throughthe turn plate 5 and partly through .the material of thedoor-Gg as at 17, thus Fig. 5.

A small keyhole, as 19, is provided in the back plate H concentric with the turn plate 5 adapted to receive the center extension 20 of the key for retaining the key centered during rotation thereof for uniformly operating the two extensions 13 of the locking plate.

It is a feature of this invention that the lock plate 4 comprises extension parts 21 whichproject outwardly from the compartment 3 below the lower end of the door plate Gr so as to serve as appropriate means by which to connect the door with the bank structure. The extensions 21 are provided 1 with fingers 22 adapted for engaging behind portions of the stop members 2 for constituting a'simple hinge connection of the door with the bank structure. These fingers 22 also cooperate with adjacent corner portions of the'plate G to provide recesses 23 by which conveniently to enable assembly of the fingers 22 behind the stop -members 2. Through the medium of the recesses 23 the door may be readily manipulated so as to engage, or disengage the fingers 22 with the tion.

stop members, thus rendering the door detachable upon occasion.

. Any suitable means may be employed for connecting the back plate H with the door plate Gr, but preferably the door plate is formed withtangs, as 2 1, integral therewith and bent over upon adjacent portions of the.

back plate to provide the required connec- The turn plate 5 is preferably held in poi sition by being formed with a central up standing portion 26 engaging within a circular opening 27 provided in the door plate G. The inner marginal portion of the turn plate is received between the rear surface 7 of the doorplate and the opposing surface of the extensions 13 of the lock arms 6 and T' thus holding the portion 26 firmly in position within the opening 27, but leaving the turnpla'te free to rotate under impulse of the key In assembling this 'locln-it issimply neccssary to place the lock member 1 in position within the back plate H, as seen in Fig. 4, then lay the turnplate 5 in its approximate position over the keyhole 19, and apply the door plate Gm. By turning over the tangs 24 the whole structure will be.

properly connected together and ready for assembly with the bank. There are no rin s or lar e number of se Jaratel formed parts likely .to become derange Each of the parts is simple and substantial;

and when assembled the device is thoroughly practical and efficientin all respects.

Any suitable means maybe employed for limiting the rotation ofthe key, but prefin the accompanying drawings, shall be-interpreted as illustrative only and not in a v7 limiting sense. 7
