IMPROVMENT IN 'THlLL-GOUPLING.

TO ALL WHOM I'l MAY CONCERNMk Be it known that I, LUMAN SQUlRE, of Norwalk, in the county of Huron, and State of Ollio, have invented a new and improved 'lhill-Conpling; and I do l1creby cleclare that the following is a full and exact description thereof, reference being had to the accompanying dra-wings, making a part of this spccilcation, and to the letters of reference marked thereon. In the drawings?- Fignre 1 represents a perspective view of my invention.

Figure 2, a bottom view.

Figure 3, a side view without the coupling-pin.

Figure 4, a 'side view of the orifice for the shoulder of the pin and Figure 5, the coupling-pin.

This invention consists of a thill-eouplii'ig provided with a spring which, by virtue of its elasticity, exert-s a pressure upon the coupling-bolt suicient to hold it firmly -in place, and, by virtue of its pliancy, admits ci' the withdrawal ot' such pressure, and the consequent removal ot' the bolt, as is hereinafter fully described.

To enable those skilled in the art to make and use my invention, will now proceed to describe its construction and operation.

A represents a section o'l' a carriage-axle. 'B represents a metallic yoke or clip, placed upon the axle, and provided with screw-threads upon its ends, which project below the axle far enough to enable the shauklc of the coupling C to be placed upon them in. contact with the under side oi' the axle, and also to enable nuts a a to be screwed upon them. b b represent ears projecting upward from the shank c, provided each with a hole, d, through which passes the coupling-bolt E. F represents a piece of wire, passed at its centre about the rear end of the clip B, between the shank c andthe nut a, where it is securely held, and running thence in two diverging arms e c to the forward corners of the shank c; there at thc points 'i cach arm is bent nearly to u rightvangle, and passing upward a short distance is curved 'at /c over the bolt E, at the outer side of each of the ears b. At the point h, near the rear nut, both arms of the wire F are in contact with the under side of the shank c, and froui these points both arms recede from the shank, passing downward as they pass outward, so that the points of i'lexion z' are a quarter of an inch, more or less, below the bottom of the shank. When the curves 7c are passed over the bolt E, the arms e e shall bc drawn a little above the position they would naturally. have assumed, and thus, byvirtue of their elasticity, exert a pressure uponthe coupling-,bolt E suiiicient to hold it firmly in its place. One of the holes, d, issemi-elliptic in shape, and a shoulder, Z,1is made on the bolt, next the head of a corresponding form, to fit in the said hole, and thus be prevented from turning. Near the other end of the coupling-pin is a. groove, m, in which one of the curves k rests, in order that the pin may not work backward out of one or both ears. When it is desiredto remove the pin, it is only necessary to press the arms n e upward'with one hand, when the pin may be easily withdrawn with the other. I

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

'lhe spring-arms e e', in combination with the bolt E, provided with the shoulder l, semi-elliptic i'n its transverse section, when constructed and arranged as setforth.

LUMAN SQUIRE.
