PATRICK W. DOHERTY, OF BOSTON, MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent No. 247,023, dated September 13, 1881.

y Application tiled February 9, 1881. (No model.)

To all 'whoml it may concern Beit known that I, PATRIGKW. DOHERTY,

i ofBoston, in the county of Suiolk and State of Massachusetts, haveinvented certain new and useful Improvements in Staples, of which the following is a full, clear, and exact description.

This improved stapleis in substance formed of a bow-piece of metal, one arm of which terminates in a. plate that projects to each side of it, and the other, together with said plate, is shaped to be interlocked with and disengaged from the other, and in such manner that interlocked the bow-piece ot the staple is closed,

and it is so held against opening, and thus the i-iikaiii, hook, ring, or other contrivance or device suspended froml the staple Ais secured against escape, accidental for otherwise, and that disengaged the staple is then open forthe l improved staple is illustrated for convenience .V

. the position desired.

as desired,

suspension or removal of the chain, hook, &c.,

all substantially as hereinafter described. f

kIn the accompanying plate ot' drawings my only in lconnection with the chain-stopperof a Y wash-tub, and Figure l is a vertical sectional view; Fig. 2,a perspective view ot' the staple;

Figs. 3, 4, 5, 6, undl 7, face and sectional views` thereof, all as is obvious from the description which follows.

In the drawings, ct represents a bow-piece of c, which projects to each side thereof, and by preference is made in one piece with the bow a, and in cach part of such projection is provided with a screw-hole, f, for convenience in attaching it, and consequently the staple,in The arm g of the bow a has a length and direction to pass beyond the edge l of the plate c, at which the arm b meets said plate, and in such prolongation it and the plate are constructed to be interlocked with each other in a manner to close the bow a., to prevent escape, accidental or otherwise, of the chain A, which, as shown, is suspended from the-bow, and to hold the arm firmly in such position against any strains or pulls upon the bow in the direction of the length of such arm g. This relative construction of the arm g and plate c (shown at m) consists in making the arm g tthe bow a with a taper at and along each edge, and with the wider end n the :far-

ther from the bow, and in correspondingly rey cessing the contiguous face o ofthe plate; and that shown at?a consists in prolonging the arm g to the farther edge sy of the plate, and there' projecting it over andaganst such edges, and

in recessing, as at t, the face ot the plate to i receive the part of said prolongation which crosses it. n f

The staple herein described, after having suspended from it achain or otheudevice, when used, is'to be fastened in any suitable manner-as, for instance, by screws-in position against any suitable support, with itsinterlocking face of the plate c and bow-arm g at l rest against such support. Thus the bow is not only closed, but at the same time rigidly fixed, against opening, accidentally or otherwise, forthe escape of the chain, Svc., because of any pull or strain thereon, all for the rea-v l Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The within-described staple, consist-in g of the two arms b and y, connected by the bowed portion a, the end of the arm b being provided with a plate,c, and having means to connect Vand interlock it with the free end of thearm g, substantially as and for the purpose described.

2. A staple consisting of the two arms b and g, connected by the bowed portion a, the arm b having a plate, c, provided with a tapering my hand in the ,presence of two subscribing y Witnesses ALBERT W. BROWN, WM. S. BELLOWS.
