Specification'of Letters Patent.

Application filed October 25, 1917. SeriaI No. 198,421.

To all whom it may concern:

Be it known that 1, CHARLES S. BARNARD, a citizen of the United States, residing at Bridgeport, Fairfield county, Connecticut, have invented certain new and useful Improvements in Latches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which is appertains to make and use the same.

This invention relates to certain new and useful improvements in a latch and it has for a principal object to simplify the construction and reduce the number of parts for economy in manufacture.

The invention further resides in such salient features as will hereinafter be pointed out in the specification and defined in the claims, reference being had to the accompanying drawing wherein- Figure l is a front elevation of the im proved latch mounted on a swinging door and engaged with its keeper;

Fig. 2 is a transverse section on line 22 of Fig. l, and

Fig. 3 is an inside or back elevation of the latch per 86.

In the drawing, 1 is the swinging door and 2 the door frame which has a striker or keeper 3 mounted thereon, said keeper being bent from a single length of sheet metal to form a goose-neck design with the free edge spaced off above the frame to permit of the latch bolt engaging therebeneath.

The latch comprises a box-like casing 4 preferably of rectangular design and opened at its base as shown in Fig. 3 to afford access to the spring 5. In a pair of opposing side walls are formed the slots 6 and 7 out of alinement with each other, the slot 6 being in a higher plane than slot 7. The latch bolt 8 and handle 9 are integrally connected, being formed from a single strip of metal, said latch bolt being slidably arranged in the casing slots and curved outwardly adjacent the slot 6, as at 10, so that when the bolt is retracted the handle will be moved outwardly away from the door and thus protect the fingers from becoming scratched by abrading the door. The keeper-engaging end of the bolt has stamped therefrom a teat or lug 11 to act as a stop by abutting the adjacent side of the casing and thereby prevent accidental withdrawal of the bolt.

Intermediate its ends, the bolt is provided in one side with a pair of parallel and in clined incisions or slots 12, which define a tongue 13, the sides of the slots being roughened or serrated, as depicted in Fig. 3. The coiled spring 5 coils about the tongue at one end and extends at an angle to the bolt, being likewise secured at its opposite end by a tongue or pin 14 provided in the casing in normal alinement with tongue 13.

In practice, when the bolt is retracted against the tendency of the spring the latter has its ends offset so that a lateral force is also acting on the bolt to project it. By simply pulling on the handle the bolt is retracted from its keeper and the handle is thrown outwardly away from the door. Consequently, the fingers will not rub against the door and become scratched or injured.

The latch is exceedingly simple and economically constructed, comprising only three parts which may readily be assembled in a very expeditious manner. The casing and bolt may be stamped from sheet metal, providing both for lightness and cheapness in their formation as well as durability.

What is claimed is:

1. A latch comprising a box-like casing provided in its front and rear walls with slots, the slot in the front wall being in a plane nearer the base of the casing than the slot in the rear wall, a flat sheet metal bolt slidable in said slots and having its ends normally projecting beyond the respective slots, stop means on the bolt to engage the casing to limit the withdrawal of the bolt, and a handle formed on the rear end of the bolt outside the casing, that portion of the bolt adjoining said handle being curved at the point where the bolt passes through the slot in the rear wall so as to throw the handle outwardly in a plane farther removed from the base of the casing when the bolt is withdrawn.

2. A latch comprising a box-like casing opened at its base and provided in a pair of opposing side walls with slots, one of which is arranged in a higher plane from the base than the other slot, a latch bolt slidably arranged in the casing slots and projecting at each end from the casing, a teat struck from one projecting end of the bolt to serve as a stop against withdrawal,

Patented July a, rate. d

a handle formed on the opposite projecting end of the bolt, and spring means for projecting the bolt,

3. A latch comprising a box-like casing opened at its base and provided in a pair; of opposing side walls with slots, one of 4. A latch comprising a box-like casing opened at its base and provided ina pair of! opposing side walls with s1ots,- one of which isarranged in a higher p1anefr0m= the base than the other; slot, alatch bolt slidably arranged in the casing slots and projecting at each end from the casing, a teatfstruck from one projecting end of the bolt to serve as a stop against withdrawal, a handle formed on the opposite projecting endof the bolt, one edge of the bolt having apair of inclined slots defining a tongue, a normally alined tongue in the casing, and a 2 coiled-springengaging over the tongues for projecting the bolt.

In testimony whereof I afiix my signature in presence of two witnesses.

CHARLES S. BARNARD.
