Application March 17, 1941, Serial No. 383,726

This invention relates to latching or securing ymechanisms for drawers and other closure members.

In drawer ling cabinets, particularly those of fireproof type which have walls Vof re resistingI leasably retaining the drawers closed and also for closing the drawer heads tightly against cooperating seats surrounding the open ends :ofthe drawer compartments in order to effectively-close kthe compartments againstl the entrance orpassage of names or hot gases.

An object of this inventionis to provide novel improved latching means for filing cabinet drawers and other closure members adapted to .accomplish these results.

Other objects of the invention arel toi provide a latching mechanism of novel construction which operates automatically to hold the drawer closed and is readily operable for releasing the drawer and, in addition, for rmly pressing the drawer head against its cooperating closure seat to insure an effective closure of the drawer com- .vpartment;also.to provide a practical and desirable'latchingfmechanism including an operating handle which, by movement thereof, acts to unvfasten the drawer, andA by a diiferent movement thereof, functions to press the drawer head tightly against its closure seat.

Further objects and advantages of the invention will appear from the following specification of the preferred embodiment of the invention, shown in the accompanying drawings, and

the novel features. of the invention are setforth in the appended claims.

Insaid drawings:

Fig. 1 is a transverse, sectionalv elevation through a le drawer on line I-- I, Fig. 5, equipped with latching mechanism embodying the invention, and showing the latched position of the parts.

Fig. 2 is a fragmentary, similar View showing the released 4position of the parts.

Fig. 3 is a fragmentary, similar view showing the latch moved to the position for pressing the drawer head against the cooperating closure seat.

Fig. 4 is a Ysectional plan view on lined-Il, Fig. 3, but showing thenormal latched position -of the parts.

Fig. 6 is a sectional elevation of one catch and keeper on line 6 6, Fig. 4.

Fig. 7 is a sectional plan view, showingthe relation of the catch with its keeper when the drawer head has been forced-in against the closure seat.

The drawings-illustrate the application of the improvedlatching mechanism to a drawer of a re resisting or heat insulating cabinet.

Al represents the cabinet and BI adraw'erarranged to slide inwardly and outwardly in a drawer compartment in the cabinet, which is preferably of fire resistingor heat insulating construction. The drawer is provided with a front wall or head C, also preferably of re resisting` or heat insulating construction which, when the drawer is closed, is adapted by Contact or cooperation with a closure seat Aon thewalls of the cabi-net surrounding the' open, front -end of the drawer compartment, to tightly close or seal said compartment. rIhe cabinet walls and the drawer head may be of anysuitable fire, resisting or heat insulating construction; and theconstruction or formation of the closure seatd on the cabinet and the cooperating marginal portions d of the drawer head maybe of any usual or suitable character adapted, by pressing the drawerhead inwardly against the closure seat, to tightly close the joint between the drawer head and the seat. Also the drawer may beslidably kmount'edin the drawer compartment in any suitable way.

As illustrated in the drawings, the latch mechanism comprises .two catch elements Il! arranged at opposite sidesof the drawer and eachadapt'ed to engage and cooperate with a keeper element I I `fixed on the adjacent side wallv of the drawer compartment for releasably securing the. drawer in closed position. Each catch elementi@v is of langle form having a shank or bodyportion' I2 extending transversely of the ldrawer and a rear- .wardly projecting hook I3 at its outer end adapted to engage the companion keeper for holding the drawer closed. The catch 'shank is arranged to slide transverselyparallel with the way Il between the middle portion (of the plate I4 and the wall of the ,drawer head. 'I'he guideway I1,` thus `formed permitshorizontal sliding movements of the catch transversely ofthe ,drawdrawerV compartment.

secured at one end to the front end of a rock shaft 2| which extends through and is journalld in a suitable bearing 22 in the central portion of the drawer head and has a cross piece 23 fixed to` its rear end. The opposite arms of the cross piece 23 are pivotally connected at 24 to the actuating links or bars I9 for Vthe two catches at the opposite sides of the drawer, so that by rocking the handle 20 downwardly, the links and the two catches at opposite sides of the drawer are pulled inwardly, while by rocking the handle upwardly, the two links and catches are shoved outwardly, or away from Veach other.

Each catch is yieldinglyurged or held downwardly by a suitable spring.V For this purpose, a coil spring 25 is shown for each catch, connected atV one end to a stud or projection 26 on the drawer head and at its other end to the catch at a point between the catch pivot and its l outer end, sothat the pull of the spring tends to depressthe catch hook. Each catch hook may be made with a bevelled inner end face 21 adapted, when the drawer is closed or moved inwardly, to engage a laterally projecting part 28 on the .front end of 'the companion keeper and ride up on the same, until the hook clears the part 28, when the spring 25 will pull the catch hook downwardly in rear of the keeper part 28, thus securing the drawer in closed position.V Instead of bevellingV the catch hook, the front end of the lateral projection 2t 'of the keeper could be bevelled to cause the hook to ride over and engage the keeper when closing the drawer. To release the drawer, the operating handle 20 is rocked downwardly, and this, operating through the links I9,.wi1l draw the catches horizontally inwardly out of engagement with the lateral parts 28 of the keepers, `thus disengaging thecatches from the keepers and permitting the opening of the drawer;

As-.before explained, the operating handle 2U is depressed for pulling the catches inwardly to thus disengage them from the keepers, while by .raising or rocking the handle upwardly, it shifts Athe drawerand, consequently, outward sliding movement; of the catch hooks against these inclined faces .will act to forcibly move the drawer inwardly and press the `drawer head tightly against the seat d, thus e'ectually closing the Manifestly, the laction would be similar .if the 'forwardly facing surfaces [Normally the handle`20 and catches III'Y are vmaintained vina middle position in which -the catches engage the keeper parts 2a and hold' the drawer in closed position, andfrom which middle position the catchesv are' pulled inwardly to release the drawer, or are shoved outwardly for forcing the drawer head against the closure seat d'. For thus releasably retaining the operating handle and the catches in this middle position, suitable spring and detent means are employed, which means, as shown in the drawings, are constructed ,as follows: The pivot screw or pin I8 which connects each catch to its actuating link I9 projects into and is adapted to travel in an elongated horizontal slot 29 in the catch guide 'plate I4. A spring wire 30 coiled about the are releasably held seated in these notches by the catch springs 25. The pivots and notches thus vact as detents which releasably hold the handle 28 horizontal and the catches in their middle positions against the tendency of the handle spring 38 to raise the handle and shove the catches to their'outer positions. But by pulling the handle upwardly by hand, the catches will be shoved out andtforceA the drawer head against its closure seat, as before explained, and the catches will be held in their outer positions by the spring 30 to maintain the drawer head in tight contact with its seat.

As shown, the slots 29 in the catch guide plates I4 are made with detent depressions or notches .32 in jtheir upper edges as well as in the lower edges. This enables guide plates of a single form to be used either at the right or left side of the drawer, and avoids the necessity of making right We claim as our invention:
