Lette/rs Patent No. 88,192, dated .Ma/rch 23, 1869.

IMIPROVED BREAST-STRAP SLIDE.

The Schedule referred to in these Letters Patent and makingpart of the ma To all whom it may conce/rn tion, in which- Figure l is a front View, showing the manner of applying one of: the breast-strap slides to the neck-yoke. Figurel is an enlarged perspective view of the'breaststrap slide attached to the ring of a neck-yoke.

Figure 3 is a top view of the slide.

Figure 4 is an end view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this linvention is to improve breaststrap slides, which are used for attaching the breaststraps of harness to the ends of a neck-yoke of a draughtpole, by constructing the hooks, or horns which keep the slides in place on the yokerings, upon the edges of the slides, whereby the latter can be manufactured with greater facility than hitherto, and will possess several advantages over breast-strap slides hitherto used, as will be hereinafter' explained.

I am aware that prior to myinvention, breast-strap slides for harness have been made of a curved, orarched shape, terminating at their ends in eyes, and having hooks, or horns formed upon their concave surfaces, for preventing the slides from casual displacement while in use. I do not, therefore, desire to be understood as making claim of invention to breast-strap slides, c'onstructed altogether in this manner.

To enable Others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanying drawings, A represents the inverted arched body ofthe slide, which may be made of any desired length and curvature, and which terminates, at its extremities, in oblong rectangular eyes O C,

adapted for receiving through them a breast-strap, as'

shown in fig. l.

The edges of the body, or arched portion A, are hanged, as shown at a a, the flanges extending downward, and serving to receive the'brest-strap between them, and protect its edges/from wear; also serving to strengthen' the body A, and keeping in place that portion of the breast-strap which passes beneath the body of the slide.

The` curvature of this slide is preferably made, as near possible, so as to conform to the curvature which the lower portion of a breast-strap would assume, if allowed V to hang freely or naturally from a collar, thereby-allowing the slide to play freely through the yoke-ring D, without much friction or resistance.

In cross-section, the upper surface of the arched portion Aof, theslide is convex, so as toaiford a suitable bearing for the ring D ofthe neck-yoke E.

My improvement consists in constructing, upon one edge of the slide A, hooked-ring sto1')s,or"horns B B, for the purpose of preventing the ring D from slipping off the ends of the slide, by violent lateral vthrusts of the draught-pole, or the lateral motion of the slide through the said ring. y y

These stops, or horns B B extend outward from the edge of the slide, and turn inward, so as to point in opposite direction toward each other, as shown in iig. 3, vand they are both located at the extremities, or upper ends ofthe slide.

Thus constructed and located, it will be seen that the entire upper concave surface of the slide is unobstructed, and that the ring D will be allowed to play freely upon such surface, between said stops, or horns, and while this is the case, the latter will eifectually prevent a casual displacement, or slipping off of the yoke-ring, either by lateral or Vertical movements of the draught-pole and neck-yoke. l

It will be seen, by reference to the end view, iig. 4, the ring-stops, or horns B, are in the horizontal plane of the eyes C O, and that these horns wholly. extend beyond the edge of the slide A. Consequently, the slide, with such horns formed upon it, can be produced of cast-metal, without using a core in moulding it, thus` enabling me to manufacture the slides much cheaper, and with greater facility than if they were made with horns arranged in the centre, or inside, as hitherto.

Having described my invention,

I claim, as'a new and improved article of manufacture- A breast-strap slide, having its ring-stops B B, constructed upon one edge, as shown and described.
