LOCKING CABINET DOOR nFiled Nov. 26. 1929 I f yl INVENTOR 1301mm 1.1 M!

BY H/S ROLAND A. FURLONG, OF ROCHESTER, NEW YORK, ASSIGNOR THE YAWIXEAN & EBBE I "res PA ENT Price- MANUFACTURING COMPANY; OF ROGHESTERQNEXV YORK, A CORFGRATION OF NEW YORK LOCKING- CABINET noon Application filed November 26-, 1929; Serial No. 409x72;

This invention relates generally to a looking door structure particularly useful in cabinets for visible index trays. In accordance with the invent-ion it is proposed to mount a door at the front of the ca met and hingedly support itat its lower edge so that when released the door may be swung tor wardly and downwardly intoa'horiZont-al position in which, if desired, it may then he slid rearwardly into the cabinetalong ways provided for that purpose. When in closed position the door is latched by a springpressed keeper which may be retracted by a finger pull. A lock is mounted at the lower portion of the cabinet in operative relation to the latch so that the tumbler may be thrown into its path and prevent its retrac tion so as to lock the door.

Another object of the invention is to provide in a door of the character described a detent which shall extend from its upper edgeto its lower edge and form a reentorcing element therefor.

Other features of the invention will be described in greater detail hereinafter in connection with the description of the embodiment shown in the accompanying drawings, in which:

Figure l is a view in front elevation of the improved cabinet showing the door in vertical closed position and indicating relationship between the lock and the detent.

Figure 2 is a view partly in side elevation and partly in section of the cabinet shown in Figure 1.

Figure 3 is a fragmentary detailed view in section taken on the plane indicated by the line 3-3 of Figure l and looking in the direction of the arrows, the bolt of the lock being engaged with the detent to lock the door.

Figure 4 is a view similar to Figure 3 showing the relation of parts when the bolt of the lock is retracted but the detent engaged for latching the door.

Figure 5 is a view similar to Figure 1 but showing the detent retracted to release the door.

the door when fully opened and also indieating in dotted lines how it may be'slid into the .cabinetwhen in horizontal position. Figure 7 is detailed'view in transverse section through. plane indicated by the lin 7-7 of Figure 4 and looking in the direction of the arrows and showing the supporting pintles for the door. e The cabinet illustrated in the drawings is formed of sheet metal and it is in such constructions that the improvements will find their greatest usefulness.- This cabinet, which is completely enclosed except for the front, accommodates a bank of horizontally disposed trays a such fas may for instance, for visible index cards. The front of. the cabinetis closed by a vertically disposed door Z In the opposite edges of this. door near the bottom are mounted laterally extending pintle pins 0 one or both of which may be pressed outwardly by springs c which may facilitate assembly and disassembly of theparts. These. oppositely extending pins 0 when the door is in lowered position may engage suitable guide flanges (F on the jainb forming the opening of the cabinet, thus holding the door in proper relation to the cabinet at all times. When. the door is swung forwardly and downwardly to a hcrizontal position, as indicated in dotted lines irr'Figure 6, it is in suchv relation to a space 6 incorporated in the cabinet to permit it to he slid rearwardly into the set to a greater or less extent. YVhen in this position the protrud ing part ofthe door is, of course, very firmly supported and may itselfserve as a shelf or support for. the trays within thecabinet or any other objects. Thenin vertical position, asillustratedin Figures 3, L and 5, the door rests on its bottom edge. directly on the base of the cabinet. In this position it is desirable to provide adetent by which the doormay be 'releasably retained tion and also lo'clc to secure the cont of the cabinet. In the improved construcsshown as formed with a pe- Slidably engaged with the upper and lower rails ot'this frame is a the cabinet taken on the be suitaole;

the relationship illustrated constitutes arescribed below.

enforcing element for the framing aside from SGIVIILO the'additional function-s de f, which. may be beveled, is adapted to enteran opening 9 provided in the frame of the cabinet. To the detent f is secured a finger pull 9 which is disposed adjacent the upper edge of the door and this finger pull may be moved downwardly to disengage the upper end f of the detent from the opening g so as to permit the door to be dropped and opened. The lower end of the detent f is supported on a spring h of any suitable character but shown as a leaf spring di-sposed within the lower hollow rail of the door frame. Retraction of the detent fby the finger pull 9" is opposed yieldingly by the spring h which normally urges the detent in lElCClllll engagement with the opening 9. Upward movement of the de tent is limited by shoulder f formed thereon. The retracted position of the latch is illustrated in Figure 5.

\Vithin the base of the cabinet on the inner front wall is secured the case of a lock is of any suitable character, thekey slot 76 being presented at the front wall ofthe cabinet below the do r. The bolt k of this lock is illustrated in Figures 1 and 3 as protruded while in the other views it is illustrated as retracted. Since the assembly is such that it is preferred that the bolt shall not engage the lower end of the detent 7 directly a loose plunger Z is shown as mounted within the lower hollow rail of the door frame and'disposed normally in line with the lower end of the detent f and the bolt The plunger Z may be secured conveniently to a leaf spring m also secured within the lower hollow rail of the door frame, this spring serving to urge the plunger towards the bolt normally, as illustrated clearly in Figure 7. hen thebolt is protruded it engages the lower end of the pluiwer Z and forces it upwardly until the spring 171 is in juxtaposition to thespring lVhen the parts are in this position it is evident that the detent 7 cannot be moved downwardly by operation of the fin er pull 9 and necessarily remains engaged with the opening g. The door is thus locked until such time as a key is insertedin the slot 70.

and the bolt of the lock retracted to permit the plunger Z-to move away from the lower end of the detent'f.

-The entire construction is. rugged, simple to manufacture, easy to assemble, pleasing Its'upper end indicated at.

the spirit of the invention, the scope of which is defined by the appended claims.

What I claim is:

1. The combination of a vertically disposed door hinged along its lower edge to a jamb, a vertically disposed slidable detent extending between the upper and lower edges of the door and normally engaging the jamb adjacent the upper edge of the door, a spring engaging the'detent to oppose its retraction yieldingly and a lock mounted in the amb with its bolt movable into cooperative relation with the lower end of the detent to prevent positively its retraction.

2. A door jamb, a door having a frame formed as a hollow rail extending around its perimeter, avertically disposed slidable detent extending between the upper and lower rails of the door, a spring within the lower rail engaging the lower end of the detent, a plunger mounted in the lower rail in line with the lower end of the detent, a spring to urge the plunger normally away from the lower end of the detent and a lock mounted on the jamb and having a boltmovable into engagement with the plunger to urge it into the path of movement of the lower end of the detent to prevent its retraction.

3. A door jamb, a door having a frame formed as a hollow rail extending around its perimeter, a vertically disposed slidable detent extending between the upper and lower rails of the door, a spring within the lower rail engaging the lower end of the detent, a finger pull supported on the upper rail of the door and engaged with the detent to per mit its retraction, a plunger mounted in the lower rail in line'with the lower end of the detent, a spring to urge the plunger normally away from the lower end of the detent and a lock mounted on the amb and having a bolt movable into engagement with the plunger to urge it into the path of movement of the lower end of the detent to prevent its retraction. j V
