LOCKING DEVICE FOR CABINETS.

Specification of Letters Patent.

Patented June e, 1920.

Original application filed May 31, 1916 Serial No. 100,921. Divided and this application filed January To all whom, it may concern:

Be it known that I, FRANK H. Honnnc, citizen of the United States, residing at Green Bay, county of Brown, and State of Wisconsin, have invented new and useful Improvements in Locking Devices for Cabinets, of which the following is a specification.

This application is a division of my former application for Letters Patent for paper feeding cabinets, filed May 31, 1916, Serial No. 100,921, patented Apr. 23, 1918, No. 1,263,669.

The object of the present invention is to provide locking means for a cabinet of this type whereby the lid or door of the cabinet may be secured to the body thereof near the upper end by a latch which will automatically engage and lock the cabinet when the door is closed and which latch can only be released by a person familiar with the structure of the latch and of the cabinet, the lock being so arranged that access to the latch may be had only through the opening or slit through which the paper is discharged from the cabinet.

More particularly the object of my invention is to provide a form of latch for a cabinet of the described class in which the latch may be located near the upper end of the cabinet and provided with a latch operating arm extending through suitable guides within the cabinet to a point near its lower end, whereby access to the operating arm may be had through the discharge opening or slit at the lower end of the cabinet.

In the drawings- Figure 1 is a front elevation of a paper feeding cabinet embodying my invention with portions of the front wall broken away to show the interior sheet starting and cabinet locking mechanism.

Fig. 2 is a sectional view of the same drawn on line 2-2 of Fig. 1 but showing a paper package in position.

Like parts are identified by the same reference characters in both views.

The cabinet is preferably constructed in two sections, comprising a back section A and a cover section B hinged together at C and with the side walls of the cover section telescoping over those of the back section. The cover section is provided near its upper end with a hook shaped bracket B and a locking bar A is mounted to slide upon the Serial No. 143,244:.

rear wall of the back section and is provided at its upper end with a latch a adapted to engage the hook shaped bracket B when the bar A is pulled downwardly. The lower end of the cabinet is provided with a slot, or left open for the discharge of sheets of paper, and by inserting a tool through this lower end of the cabinet, a projection a carried by the bar A may be engaged and the locking bar manipulated to lockor unlock the cabinet. When unlocked, the cover section may be swung downwardly upon the hinge pin C to expose the interior.

The package of paper D is supported from a bracket E within the cabinet as described in said former application. The operating lever F, spring G, brush H, and guide flanges J therefor are the same in structure and mode of operation as described and claimed in said former application and de tailed description herein is therefore deemed unnecessary.

It will be observed that the hook shaped bracket B on the cover section has an upturned inner extremity b. The locking bar A may be conveniently supported from the back wall by guide pins K at their respective ends and inserted through the back Wall and through slots L in the locking bar A, the length of the slots limiting the vertical movement of the bar A. The latch a, is supported from the upper end of the bar A by a horizontal arm A which is normally.

at a sufficient distance from the upper end wall of the cabinet to allow a vertical movement of the bar A. substantially equal to the length of the slots L whereby the bar A may be pushed upwardly until the arm A and latch a occupy the dotted line position in which they are illustrated in Fig. 2.

In the construction shown, any ordinary tool adapted to enter the lower end of the cabinet may be used to push the bar A upwardly and release the latch a. The character of the tool will, of course, depend upon the specific form and shape of the cabinet and upon obstructions, if any, within the cabinet between the slotted lower end, and the latch operating piece a. "Whenever the door is to be closed, the latch operating bar A will be raised preparatory to closing the door and released when the door is fully closed, whereupon the latch a will be automatically engaged, since the bar A will drop by gravity unless manually supported.

It will be understood that when the cabi net is filled the packagevof paper will be pushed backwardly and will cover the lower end of the bar A, but as the paper is with drawn the package will be pushed forwardly by the feeding spring as described in my guide pins secured through the rear wall of the back section, one above the other, a lock ing bar having longitudinal slots mounted upon said guide pins adapted for vertical reciprocation, a horizontal arm at the upper end of the said bar with a hooked free end serving as a latch adapted for engaging said bracket when the bar is in its normal lowered position with the cover section closed,

and an inwardly extending projection upon the lower end of the bar adapted for access through said opening for elevating the bar when the cabinet is empty whereby the latch is released during the unlocking operation.

In testimony whereof I affix my signature 1n the presence of two witnesses.
