2 Claims. (01. 292-332) This invention has to do with improvements ment with the latch keeper, the roller being held in spring latches and consists of the hereinafter against longitudinal escape from the lever by a described novel combinations and arrangements washer 3| held in place by heading the end of of parts together with parts which, in themthe latch lever as shown at 32.

5 selves, are novel, by virtue of which I aim to For yieldably holding the latch lever in either 5 provide a spring latch which is economical of its open or closed position, I provide a leaf manufacture, durable, and in which the latch spring 40, which rests as one end on body lug lever is yieldably but positively held in the dell and at its other end it rests against and has sired position by novel means. a portion 42 projecting downwardly into a coil Other objects and corresponding accomplishspring 44 vertically mounted in the casing and 10 ments will appear obvious to those skilled in the socketed between body lug 46 and one side of art from the following description wherein, by the body I I]. Spring 40 is undulated so as to way of example, I describe a preferred embodi present substantially at its medial portion a ment of the invention. In this connection, howraised portion 47 with relatively lower portions ever, I wish it understood that while I resort 48 and 49 on each side thereof. The lug 24 15 in this description to various details of combihas a curved face which slides over the raised nations, arrangements and parts, my invention, spring portion 47 when the latch lever is moved in its broader aspects, is not to be restricted to between its open and closed positions, and since such details. On the contrary, it is to be recoil spring 44 at all times additionally urges striated only as appears from the appended leaf spring 40 against lug 24, the latch lever 20 claims. is positively but yieldably held in either its open For purposes of the following description, I or closed position. shall make reference to the annexed drawing, in To manually move the latch lever about post which: I8, which acts as a fulcrum for the lever, I pro- Fig. 1 is a back view of my latch, in elevation, vide a handle 50 pivotally mounted on the ex- 25 with the parts in latching position; terior of the body between a pair of lugs 5I by a Fig. 2 is a view similar to Fig. 1 except that pin 52 extending through the lugs and an openthe parts are in open or unlatched position; ing through the handle.

The operation of my device is as follows: To Within body I0 latch lever I5 is pivotally semove the parts from the latched position of Fig. cured to post I8 by screw I6, a washer I! being 1 to the open position of Fig. 2, the handle provided between the screw-head and the top member 50 in Fig. 3 is moved to the right, which 40 of post I8, the latch lever being rotatable about causes finger 54 to move latch member 2I post I8. Lever I5 is bifurcated at its inner end downwardly, which in turn raises the outer end to present spaced fingers 20, 2|, and at what of the latch lever until it abuts stop 26 and remay be termed the under side of lever I5 there moves it from engagement with the latch keepis a lug 2 3 which presents a curved face. er 35, during which movement lug 24 rides over 45 Body I!) has at one of its sides a vertical slot hump 41 of leaf spring 40.

At its outer end the latch verse direction against keeper face 36, which lever has a portion I5b of reduced diameter, moves the outer end of the latch lever I5 down- 65 around which is provided a roller 30 for engagewardly until lug 24 is moved slightly over the spring 40, which precludes any accidental open ing or closing action. Furthermore my device is easy to assemble or repair inasmuch as the latch lever and latch handle are the only parts secured to the casing.

Iclaim:

1. In a latch device having a body, a latch bolt, a pivot member connecting said bolt be-' tween its ends to the body, a bolt actuating member operatively associated with one end of the bolt, and means for yieldably holding the bolt in a predetermined position, including: a lug on the side of the bolt substantially opposite said pivot member, a leaf spring bearing against the lug and a coil spring bearing against one end of the leaf spring to urge it against the lug.

2. In a latch device having a body, a latch bolt, a pivot member'connecting said bolt between its ends to the body, said pivot member extending through a side portion of the bolt, a bolt actuating member operatively associated with one end of the bolt to move the bolt about the pivot member, and means for yieldably holding the bolt in predetermined position, including: a lug on the side of the bolt substantially opposite the pivot member, a leaf spring rockably resting at one end against the body and a coil spring urging the other end of the leaf spring against said lug.
