The primary object is to provide an improved cabinet-safe of this character which is simple in construction and operation, readily manipulated, fire-resistant, and secure.

The invention is illustrated in a preferred embodiment in the accompanying drawings, in which- Fig. 1 is a vertical sectional view of the cabinet-safe embodying the invention, the top-closure being shown in elevation and having a portion broken away at one end; Fig. 2 is a broken horizontal sectional view taken as indicated at line 2 of Fig. 1; Fig. 3, a perspective view of one of a pair of pivot-members with which the rear portion of the cabinet is equipped; Fig. 4, a perspective view of one of a pair of housingmembers secured tothe rear end of the closure; Fig. 5, a view similar to Fig. 1, but showing the closure in the open position and the tray (shown in dotted lines) in elevated position; Fig. 6, a broken vertical sectional view taken as indicated at line 6 of Fig. 5, assuming the closure to be in closed and .locked position; Fig. 7, a vertical sectional view taken as indicated at line 'I of Fig. 5; Fig. 8, a broken verticalsectional view taken as indicated at line 8 of Fig. 1; and Fig. 9, an inner face view, partly in section, of the closure, illustrating a latching-device for holding the closure in the position shown in Fig. 5 and a key-controlled locking device for securing the closure in the position shown in Fig. 1.

In the construction illustrated, A designates a cabinet-body supported on legs A' and having the upper portions of its lateral walls provided with upwardly presented guides A2 and below the plane thereof with inwardly-open guides A3; B, a rearwardly and forwardly slidable closure forming a top for the cabinet, said closure being equipped at its front end with a handle B' and being suitable to house a key-controlled or combination-controlled locking-mechanism 1B2 and a latching-device B3; C, a tray or recordsupport which is vertically movable from the dotted line position shown in Fig. 1 to the dotted line position shown in Fig. 5, and vice versa; and D, tray-actuating mechanism mounted in the cabinet-body and operatively connected with the closure.

The cabinet-body A preferably comprises a hollow shell 1 and a lling 2 of refractory, fire- TEs PATENT OFFICE resistant material such as a suitable cement composition. If desired, a mineral wool composition may be employed as a lling.

The

sheet metal employed to form the shell 1 is suitably shaped to provide the upwardly presented guides A2 at the upper edges of the lateral walls and the inwardly presented guides A3, the latter being in the form of inwardly open internal guide-grooves.

Preferably the guides A2 are such as to provide a marginal portion 3 flush with the top surface of the closure, a depressed seat-portion 4, a deep groove-portion 5, and an inner marginal tongue-portion 6 which is somewhat below the level of the seat-portion 4.

The tongue- The closure B is shown as comprising a hollow shell 'l and a iilling of nre-resistant, refractory material 8. The lling material is suitably recessed to accomodate the locking mechanism B2 and the latching device B3.

The lateral edge portions of the closure are provided with a downwardly presented conguration which corresponds with the configuration at the upper edges of the side walls of the cabinetbody. Thus, the closure has lateral margins 9 adapted to the depressed seats 4, and has longitudinal depending tongues 10 adapted to the longitudinal grooves 5. The closure also has a main portion 11 which nts between the upper portions of the side walls of the cabinet and extends across the internal grooves A3.

The front 5 end of the closure is provided with a tongue 12 which is adapted to t into an internal groove 13 in the front wall of the cabinet-body, it being noted that the upper edge of said front wall is flush with the upper surface of the closure.

The rear end of the closure is provided with a depending portion 14 which is equipped with a tongue 14a.

The upper portion 'of the rear wall of the cabinet is cut away, thus leaving a shortened rear wall 15 which is provided at its upper portion with a groove 15a adapted to receive the tongue 14a.

Thus, the members 14 and 15 are complemental and together form the rear wall of the cabinet when the closure is in locked position.

the closed,

As will be understood from Figs. 1, 6 and 9, the key-controlled locking-mechanism B2 comprises a lock 16 equipped with a key 16a; a plunger 16b adapted to be actuated by said key; a pivotally mounted disk 16c adapted to be' actuated by the plunger 16b through the medium of a link 16d; transversely disposed locking bolts 16e having their outer ends extending into the grooves A3 and having their inner ends pivotally connected with pins 16f with which the disk 16c is equipped; and springs 16Ilr which tend always to thrust the locking bolts 16e outwardly. The disk 16c is provided with a segmental slot 16h whose ends coact with a fixed stud 17 with which the closure is equipped. In Fig. 9, it is to be understood that the locking bolts 16e have been withdrawn against the tension of the springs 16g. However, when the closure is in the closed position, the locking bolts may enter sockets 18 in the bottom of the grooves A3, as will be understood from Fig. 6.

The latching device B3 is shown as comprising 'a latch-bolt 19 which projects at one lateral edge of the closure and which is adapted to engage a socket 20 (Figs. 3 and 5) to hold the closure inl the open position; a spring 19a tending to thrust the bolt 19 outwardly; a bell crank lever 19b by means of which the bolt may be actuated; and a longitudinally disposed actuating rod 19c which has its rear end pivotally connected with one arm of the lever 19b and its front end projecting, like a push-button, beyond the front end of the closure. It will be understood from Fig. 5 that the finger-portion of the plunger 19C is disposed in such position that the plunger may be readily actuated by the thumb when the operator grasps the handle B for the purpose of closing the cabinet.

The tray C may be of any suitable form and equipped with any suitable device for holding record-cards, record-sheets, record-books, or the like. It is shown as having the form of an opentop rectangular box.

The tray-raising and4 lowering mechanism D may be of any suitable form. The mechanism shown is well adapted for the purpose. It comprises a stirrup 21 suspended from the forward end of a pair of levers 22 which are pivotally connected at points 23 with the lower rear portion of the cabinet body; a stirrup 24 suspended from the rear ends of a pair of levers 25 whose front ends are pivotally connected at points 26 with the upper front portion of the tray; links 27 connecting intermediate portions of the levers 22 and 25 at each side of the tray, respectively; and links 28 connecting rear portions of the levers 25 with clips 29 secured to the under surface of the closure B. Springs 30 connect the levers 22 and 25 in such manner as to have a slight tendency to swing the closure forwardly from the position shown in Fig. 5.

.These springs act as counter-balancing springs in the nal portion of the movement of opening the closure. The links 28 are provided with slots 28a, and the levers 25 are provided with slots 25a. Pins, or screws, extend through these slots. Thus, the links 28 have lost-motion connection with the levers 25.

Attached to the rear edge of the upper portion of each lateral wall of the cabinet body is a pivot-member 32 (Figs. 2, 3 and 5). These pivot-members preferably are in the form of castings which are suitably secured in position, as by means of rivets or bolts 33. 'Ihe members are provided at their`inner lateral faces with slots 32a which form extensions of the guides A3. The rear walls of the slots 32a are cut by relatively narrow slots 32h, the purpose of which is to provide passages for laterally projecting stops 34 with which the closure is equipped. Preferably, the locking bolts 16e serve as pivots, or trunnions, in the manner illustrated in Fig. 5. The stops 34 are in the form of flat projections which are adapted to pass through the relatively narrow slots 32h. They are then adapted to act as steadying members which engage the curved rear surfaces 32c with which the members 32 are provided; and, finally, the stops are adapted to rest in recesses 32d which provide shoulders against which the stops abut when the closure is in the position shown in Fig. 5. In this position, the latch-plunger 19 enters the perforation 20 with which one of the pivotmembers 32 is provided.

Attached to the rear end of the closure B are housing-members or shields 35. These are sector-like members adapted to house the projecting portions of the pivot-members 32 in a manner which will be understood from Figs. 1 and 2. The members 35 are equipped with attaching-anges 35a which are secured by rivets or bolts 35h to the metal shell` of the closure B.

Preferably, the closure B is equipped at the lateral edges of its front portion with guidestuds, or rollers, 36, which are adapted to travel in the guides A3 and to pass through the vertical slots 6a of the longitudinal tongues, or projections, 6, which form the upper walls of. the guide-slots A3. These rollers tend to balance the closure during its sliding movement, that is, while the closure is in the horizontal position. The rollers will pass through the vertical slots 6ab freely, however, to permit the swinging of the closure on the trunnions 16e. These trunnions may be equipped with rollers, as shown, if desired.

A brief description of the operation will sullice. Normally, the vclosure B is locked in the position shown in Figs. 1 and 6. When access to the contents of the cabinet is desired, the operator turns the key 163 and thereby retracts the locking bolts 16e. These bolts then serve as traveling trunnions. The operator grasps the handle B and pushes the closure rearwardly until the trunnions 16e engage the rear ends of the slots 32a', the steadying stops 34 in the meantime passing through the relatively narrow slots 32h. The operator then'swings the closure upwardly and rearwardly to the position shown in Fig. 5, in which position the latching device B3 latches the closure in the standing position. In the operation of swinging the closure to the standing position, the closure, through the medium of the links 28, actuates the lever and link tray-actuating mechanism D, causing said mechanism to lift the tray to the elevated position shown in dotted lines in Fig. 5. When it is desired to close the cabinet, the operator grasps the handle B and pushes the projecting thumb-piece of the rod 19e, thus actuating the lever 19h and withdrawing the plunger 19 from the socket 20 with which one of thel pivotmembers 32 is provided. The operator then swings the closure downwardly to the horizontal position, in which movement the rollers 36 pass through the vertical slots 6al into the plane of the longitudinal guide-grooves A3. The cover is then drawn forwardly to the closed position, whereupon the key 16* is turned and the locking bolts 16e enter the locking sockets 18, as shown flame to enter the cabinet, in case of fire.

in Fig. 6. It is understood, of course, that the tray is supported in the stirrups 21 and 24 in the manner illustrated in Fig. 7.

Referring again to the lateral stops, or steadying members 34, with which the closure is equipped, it may be remarked that after these members pass through the slots 32b (Fig. 3) in the opening operation, the guide rollers 36 are in position to swing upwardly through the lrecesses 6a (Fig. 1) in the upper walls of the guides A3. In the swinging movement, the members 34 engage the rear curved surfaces 32, so that the trunnions 16 (locking bolts). of the closure are held properly in position in the rear portions of the slots 32, where the pivoting action occurs.

The handle B is equipped with a guard-web 37 which is disposed close'to the upper surface of the front end-wall of the cabinet when the closureB is in the locked position. The handle itself comprises bracket-arms 37 and a gripportion 37b. The web 3'7 connects the bracketarms below the handle and is in such position as to guard the fingers against being caught b'etween the front end of the closure and the front wall of the cabinet-body in the operation of sliding the closure forwardly.

The construction described is simple, easily operated, and very secure. Because of the tongue and groove joints employed between the closure and the cabinet-body, it is impossible for The contents of the cabinet-safe are well insulated against heat, moreover.

The foregoing detailed description has been given for clearness of understanding, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of' the prior art.
