SHAFT-TUG.

SPECIFICATION forming part of Letters Patent No. 310,366, dated January 6, 1885.

(No model.)

- supporting the shafts of vehicles, and has for its object to facilitate harnessing and unharnessing the draftanimal.

The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be had tothe accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front longitudinal sectional elevation of my improved shaft-loop. Fig. 2 is a cross-sectional elevation on the line 00, Fig. 1, and Fig. 3 is a side elevation of the upper portion of the shaft-loop.

My improved shaft-loop is made in two principal sections or portionsthe loop proper, shown at A, and the metallic fastening B, by which the loop is held so asto open and close to enter and remove the shaft from it in harnessing and unharnessing the draft-animal, and by which also the entire loop is held to the back-strap C of the saddle of the harness. I make the open loop A with eyes a a, and the fastening B with lugs Z) 5, so that a strong pivot'pin, D, passed through the eyes a c and lugs b b, will hinge the loop A to the fastening B. The ends 6 c of the frame of the buckle E pass at the sides of the lugs b b, and the eye of the tongue f of the buckle is placed between the eyes a a of the loop A, so that the buckle E is attached to the shaft-loop by the same pin D by which the open loop A is hinged to the fastening B. The eyes a a are formed upon the upper end of a metal plate, A, which forms an inner metallic core to the loop part- A, and is bent around togive the required shape to the loop, as in Fig. 1. This coreplate A is covered with plates or strips of leather, as at A A which are stitched together at the edges, to inclose the eoreplate A and give a better appearance to the shaft-loop by presenting a leather finish corresponding to the rest of the harness. The leather covering A also prevents the excessive wear 011 the shafts which a metal loop would cause, and also makes the loop much more agreeable to handle, especially in cold weather. The metal eoreplate A has fixed to it the eye F, to which the eye or frame G for the under strap is pivoted. The end of the complete A, which locks with the fastening B, has an eye, a, ranging transversely, and into which eye the ends it h of the catches H H pass from opposite sides. These catches H H are pivoted on pins h h, to and between the lower plate portion, 13, of the fastening B and a back plate, I, on which latter plate is fixed or formed the loop J, by or in which the end of the backstrap 0 is held after it passes through the buckle E. The plate B of the fastening B is .pressed or bulged out transversely, as at I), to

form a recess behind it, in which is placed the spring K, and so as to press outward by its opposite ends against the upper parts, If h of the catches H II, above their pivots, and thereby force their lower bent ends, h h, toward each other. The lower end of the plate B is bent outward, as at b and then is shaped at its extremity in the form of a shallow cup or bowl, B into which the eye a of the loop A may pass for a guard when the eye is engaged by the catches H II. here the plate 13 is bent at If past the catches shoulders I) are formed, against which the catches strike to limit their throw by the action of the spring K. The pivot-pins h of the catches serve, to gether with a lower rivet, h, to bind the plates I and B of the fastening B firmly to each other, and so as to inclose the swing-catches H between them.

In harnessing the animal to a vehicle, the shafts or thills will be passed into the loop A when it is swung back on its pivot D, whereupon the eye a of the loop is swung around and engaged by the catches H H, which will firmly lock the shafts to place. It will be seen that the shafts are engaged and held by the loops without passing the ends of the shafts through the loops. In unharnessing, the upper ends,

h", of the catches II II will be pressed toward pivots D to remove the shafts from them. I

The ends If of the catches H do not project inward beyond the raised part b of the plates B, so that any lifting movements of the shafts in the loops can have no tendency to loosen or disable the catches.

I do not limit myself to the use of a leather covering for the metallic core-plate A of the shaft-loop, as the same may be coated or covered with rubber or any other suitable fabric or material which will give a proper finish to the loop to correspond with the rest of the harness.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A shaft -loop constructed with a loop part, A, hinged with the buckle E, by which the loop is hung from the saddle-strap O, and provided with a transverse eye, a, at its joint end, and the fastening B, connecting with the top of the loop, and provided with the springcatches H H, adapted to enter the eye a, sub stantially as shown and described.

2. In a shaft-loop, the fastening B, provided with the pivoted catches H H, havinginturned locking ends 71 h, head portions W76 and a spring, K, interposed between the parts If h, substantially as shown and described.

8. In a shaft-loop, the fastening B, bent at b, and extended to form the rest and guard 13 for the eye a at the loop-joint, substantially as shown and described.

4. A shaft-loop constructed with a loop, A, having a metallic core, A, and an eye, a, and hinged with the fastening B and buckle E on a pivot-pin, D, said fastening B having the back-strap loop J secured to it, and also having the pivoted catches H H, adapted to engage the" eye aof the loop part A, substantially as shown and described.
