REVERSIBLE STORE-DOOR LATCH.

SPECIFICATION forming To all whom, it may concern:

Be it known that I, AUGUST AnENs, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and of which the following is a specification.

My invention relates to improvements in that class of latches in which a longitudinallymoving latch-bolt is drawn inward by means of a thumb-bar, said latches being known as invention are to provide a simple and cheap arrangement, in the form of a double angle-lever, for throwing the bolt, and t0 makethe piece against which the thumb-bar presses changeably secured to said angle-lever, so as to project from either side of the case, to adapt the latch for use upon either a right-hand or a lefthand door. I attain these objects by the simple construction illustrated in the accompanying drawings, in which- Figure 1 is a frontelevation of my latch with the cap-plate of the case removed; Fig. 2 is a sectional view of the right-hand side of said latch, the plane of section being indicated by the line as w in Fig. 1; and Fig. 3 is afront elevation of parts of said latch.

A designates a longitudinally-moving latchbolt, beveled at its outer end, and, if desired, provided with the anti-friction lever a. Said latch-bolt is forcedinward under the influence of the keeper, upon closing the door, as in other latches, and it is forced outward by means of a suitable spring, I).

For the purpose of withdrawing the latchbolt A from the keeper when the door is closed, I secure the horseshoe-shaped piece B, having suitable engaging-lugs, c c, to the inner end of the latch-bolt. I pivot to the case at d a T- shaped or double angle-lever, 0, whose ends rest against the sides of the engaging-lugs c c, which face the latch-bolt, as shown, while the pivoted post (I is upon the other side of said lugs and in longitudinal alignment with the latch-bolt. Upon the front face of the lever C are two stubs or posts, h, which are designed to receive, one at a time, the inner end of the vertically-moving slide D. Said slide is propart of Letters Patent No. 286,250, dated October 9, 1883.

Application filedAngust 4, 1883. (Modem size to fit and receive either of said posts h. The upper and lowerside edges, of the case are slotted or recessed toreceive the body of the slide D, near its opposite end, and guide the same in its vertical movement. The lower end of the slide D has a broad head, 70, for the ordinary thumb-bars to act against in lifting the slide D. In view of the fact that this is a mortise-latch,the sidewalls of the case are brought nearer together in the vicinity of the slide than elsewhere, thereby forming the notches m for the head is ofthe slide, andpreventing said head I from projecting so far beyond the main portion of the side edges of the case as to inter fere withinserting the case endwise into a mortise. Instead of two posts h h, a single postmay be placed on the lever C, intermediately between the present location of said posts, and then make the slide D correspondingly longer.

The lock is set in the position shown in the drawings, with the ordinary thumb-bars di rectly underneath the head is of the slides. By operating either thumb-bar in the ordinary manner it is pressed upward against the head of the slide D and lifts said slide. The slide, being connected by the posts h to the lever C, necessarily imparts a swinging movement to said lever and forces the end of its upper arm against the upper lug of the horseshoe-shaped,

piece B,- to force said piece and the latch-bolt A inward into the position indicated for the respective parts by the broken lines in'Fig. 1.

and out of its guiding-recess, and place it upon the lever C, with its head projecting from the other side edge of the case-that is, the edge opposite that from which it was last removed.

I am aware that store-door latches have been shown. in prior patents as containing a vertically-moving slide at one edge of the case for being acted upon by the thumb bars, said which engaged a lug at the inner end of the 1atch-bolt;'also, as containing a double angle-lever which acted upon engaging-lugs eonnected to the latch-bolt, the middle of which lever, for being acted upon by the thumb bars, was arranged in the middle of an opening near the middle of the latch-case, to make the latch reversible also, as containing a latclrboltn'ith a changeable engaging-lug and a changeable angle-lever, one arm of which was for being acted upon by the thumb-bars, the latch being reversed by changing the lag and angle-lever to either side; and, also, as containing a vertically-moving slide bearing a cam for acting upon the engaging-lug of the latch-bolt, and changeable, so that the end designed to be acted upon by the thnmb-bars may be projected from either side of the ease for reversing. All of said prior art is hereby disclaimed.

I claim as my invention-- The combination of the latch-bolt having suitable engaging-lugs at its inner end, the double angle-lever, and the vertically-n1oving slide changeably secured to said angle-lever, substantially as described, and for the purpose specified.

AUGUST ARENS.
