To all whom it may concern:

Be it known that ll, Gamma-Anson, a citi-' zen of the United States, residing at Mar- .shclltown, in the county of Marshall and 5 State of Iowa have invented certain new and iisciiul improvements in Door Latches, of which the following is a specification, reference being nod to the accompanying drawmgs.-

to This invention relates to improvments in iiOOF. latches and particularly to those door latches which are mounted upon the baseboeccl Oi. oilier'wise ,acljacent'the floor and which nrojecc out therefrom, and which are 1:? adaptcn engage the door as it' is-swung open so as tcnoicl the dooropen until the latch is rcleaseii, these latches being released by the foot. i v

AOne of the objects of the invention is to ac pi'cvitie a latch of this character which is very simple, which may be cheaply constructed, and which is thoroughly eflective.

A further object is to provide a construction of this character so formed that one bolt holds the lat-ch and the casing together.

A still further object is to provide a latch of this description which ma be used'on doors that open either to the right or to the left without changing anything in the latch cc itself" icr object is to provide means wherelatch may be operated from either in which the-latch is operated b d not my a spring, and in whic 1 be operated by the toe on: the

' a perspecti e View of the keeper I the (icon Refieii'ing to these (lrawings, it will be seen that the casing oi": tlic latch is formed in two sect-ions A and E and that the section A is oi single casting providing a face place 16, a; sills well. ii, the end walls 12, and

the wall 13 which extends parallel to the Wall IL The wall 11 extends beyond the end walls 12 and the upper end of this end Wall is rounded and formed with a couniersnni:

screw aperture 14. The lower end of this;

end wall is also formed with a screwaperture 14 and thus the casing may be attached to the mop board or baseeboard of thewall.

The wall 11 is-preferably formed with a recess 15 and the wall 13 is formed with. a i

like recess 15, lint this recess is intersected by a latch opening-l6. The end Walls are each formed with a pair of recesses 17 at the iunctionot the and walls with the side Wells.

The face plate 10 is formed with an aperture-x for the passage of a bolt 18, and oscillatahly mounted n'pon this screw is the latch, 19..

This latch is formed eta single casting haw. ing a 'elutively'largc butt end through which the section B is also formed with a cori'esponcling arcuate slot 24 t. rough which the other enol o: the pin pa Thus the pin progects out through the sectio.

A. and B on each side thereof so ii at the latch may be manipulatcdfrom eithensici tion B is aclaptccl to rest A and be complementary thereto. section B formed of c plate of metal and recessed at its ends, as at 25, and its side edges ecljaccnt its coils the plate is recessed, as a l; 26, so that this plate fits into the re cesses l5 and 3.7 of tile sicle anti encl walls The bolt 18 passes through en aperture inthe section. B and by means of this colt the plate or section B is held upon the own ingA, the interlocking tongues an recesses formed upon the edges ofithe plate or section B and the. edges of the walls of the scction. A preventing any rotativc movement;

vided with a keeper plate 27, this plate being provided wit-h screw openings 28 Where by it may be attached to the door and pro vided with a central square opening 29 through which the head of the latch is adapted to project when the door is in engagement with the latch. The door is to be recessed behind the opening 29 in the late 27 so as to permit the projection of the nead of the latch into the opening 29 and the an gagement of this latch head with the marins of the plate, the plate being adapted to 1ft. the latch as the door is swung to a closed position.

vThe'use of this device will be obvious what has gone before. The latch casin is mounted upon the mop board with the -la h'swung outward, and when the door is qswung fully open the latch will engage the door. It will be seen that there is nothing projecting from the door which can possibly form an obstruction or which can catch on'clothes or on an object. assing through the door, and w en the cor is opened the latch is entirely covered by the door itself so that there is no possible obstruction to passing through the door in either direction. This latch is particularly designed for house doors, garage doors and large heavy factory doors, and it will be obvious that this latch without any change on their edges and one of the side walls being extended beyond the end Walls and bemg apertured .for the passage of sc ews, the opposite side walls having an a erture for the passage of a lamh, the ot or section comprising a plate adapted to rest against the side and end walls of the rst section and being recessed complemen arily t0 h recesses on the side and end Walls a single screw passing through said platev and through the opposite face plate and through the latch and acting to pivotally support the latch and hold the two sections'of the casing together, and a pin extending through the latch and through the plates of the two sections, the lates having arcuate slots through whic the pin passes.
