To all whom it may Gor/067%: I

Be it known that I; SAMUEL T. ROBRTS, a citizen ofthe United States, residing at S ringfield, in the 'County of Greene and State ol Missouri, have invented certain new and useful Improvements in Straps, of which the following is a specification.

. inforcement.

This invention relates to harness, and more especially to traces, hame-tugs, saddle-bearers, breechng, pole-straps, '&c., which of necessity must be exceedingly strong and durable and at the sametime fleXible; and my'object is to produce straps or devices of the character named or for other purposes provided with a metallic` reinforcement to increase their strength and at the same time reduce their weight and cheapen their cost without detracting in any way from their appearance.

The invention essentially' consists in constructing the strapof a pair of similar leather strips of much lighter weight, and therefore cost, than the ordinar strips and securng between them afiexib e metallic strip composed of a pluralty of strips or wires.

Other objects of the invention will herenafter ap ear, and in order that the invention maybe f flly understood reference is to be had to the accompanying drawings, in which- Figure 1 is a perspective view of a trace or tug embodying my invention. Fig. 2 is a view, partly in plan and partly in horizontal section, of the same on the line II II of Fig. 1.'

. t Fig. 3 is an enlarged section taken on the line strap in which it is desired to secure the combination of strength, light weight 3 and cheapness' of Construction, 1 indicates a pair of leather strips which may be in the form of two separate strands, as shown in Figs. 1 and upon itself, as at 2 in Fig. 5. 3 indicates jr'ows of stitchng to secure said strips reliably together near their upper and loweredges.

4 indicates a flexible metallic reinforcement preferably composed of a series. of wires clasp 7 and is adapted to engage a hame-loop, or a buckle (not shown) may be employed in a single strap doubled or folded back tially the same length-as strips 1 and secured between the ,said hollow or tubular wire 'cable being held in place by the stitching 3 above and-below it and flattened, as shown in Fig. 1, where the strap is broken away.

co iled in the form of ahollow cable of substan- Patented March 13,1906.. I

Where the'. strap is of such character that it omust be engaged by-a buckle, it .is pierced to receive the eyelets 5, said eyelets also passing through the metallic reinforcement, by preference passing through said owire cable'or reinforcement by spreadin'g or bowing its contiguous strands in opposite xdirections, as shown at 6, so as to avoid cutting, and therefore weakening, the same, as shown clearly in Fig. 3; and to guard against dislocation of the eyelets they may be brazed or soldered to the reinforcement, as at 6 Where the trace is to be eng'aged with the cockeye-loop 9, a metallic clasp 7 has its arms engaging opposite sides of the strap-rivets 8 passing through said arms and the strap to make the connection permanent, it being understood that rivets 8, like eyelets 5, will preferably pass through the metallic reinforcement. by bowing the contiguous strands cutting or in uring the same; The usual loop 9 of the type shown or of any other suitable preferrel type is pivotally engaged by lieu of said cockeye, where circumstances or the character of the strap make the use of a buckle desirable.

thereof in opposite directions, so as to avoid In lieu of the hollow cable I may employ a fiat coarsely-woven wire cable 10, as indicated in Fig. 6 but in either case the eyelets for reoeiving the buckle-tongue or the rivets for securing the clasp to the strap require no outting of the wires of said cable, and therefore will hold said tongue'or clasp reliably without danger of the leather portions of the strap being torn under any strain which can be imposed upon them. r

In Fig. 7 is shown a finely-woven reinforcement 11, through which the eyelets and rivets may extend without regard to whether the wires are cut or not, as the said eyelets also eXtend through and are brazed or soldered to the thin metal clasp 12, which clasp will be employed in all cases where ,the desideratumis a strap of great strength and maXimum fleXibilty, the latter being obtained by forcement, asin the figure last referred to.

IIO

usinga comparatively thin and light rein- A strap manufaotured as described is as fieXible as a heavier leather strap and is far cheaper, as the' leather used for tugs, traces, &c., is of a Very expensive grade and is sold only by weight. A strap embodying my improvement, furthermore, can be made of Inaterially smaller cross-sectional area than an all leather strap of approximately equal strength.

From the above description it will be apparent that I have produced a Strap which may be used in any. of the connections suggested and possesses the desrable features enumerated in the statement of the object of the inVention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A strap, comprising a pair of leather strips fitting flatly together and secured to A each other near their upper and lower edges,

a reinforcement interposed between said strips in the form of a fiattened hollow Wire cable.

2. A strap, comprising a pair of strips secured together, a reinforcement interposed between said strips in the form of' a hollow Wire cable, and eyelets extending through said strips and reinforcement.

3. A strap, comprising a pair of strips fitting and secured together, a reinforcement in the form of a fiattened hollow wire cable interposed between said strips, clasps upon the reinforcement and between the strips, and eyelets secured to the clasps and extending through the same, the reinforcement and the strips.

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