To all whom/ it may concern:

Be it known that I, JAMES A. DONALDSON, a citizen of the United States, residing at Greenville, in the'county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Horse-Detachers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to horse-detachers, but more particularly to a safety-singletree for detaching the horse from carriages and other vehicles.

. The primary object of my invention is to provide a detaching device adapted to readily receive the traces and to hold the same in engagement therewith, yet permitting the ready and easy removal of the traces in hitching or in detaching a horse, thereby lessening the time required and overcoming the difficulties usually encountered and at the same time aifording means for permitting the traces to be automatically detached in case of a runaway or other accident.

A further object is to provide a simple, efficient, and inexpensive horse-detaching device which may be readily applied to various vehicles.

With these and other objects in view the invention consists in the construction and combination of the several parts, substantially as hereinafter described, and more particularly pointed out in the claims-at the end of thedescription.

Referring to the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of a singletree embodying my invention, illustrating a portion of the traces in their normal position. Fig. 2 is a plan view of the singletree with the members released and partially folded to permit the traces to be automatically slipped therefrom. Fig. 3 is a vertical sectional view taken on the line III III of Fig. 1. Fig. 4 is a detail front elevation of the journal or union piece and the hinged or pivotedsocket-pieces. Fig. 5 is a fragmentary underneath plan view of the parts shown in Fig. 4, and Fig. 6 is a. detail plan. view of the bearing or socket for the union or'journal piece attached to the usual cross-bar.

In the drawings, A may designate the usual cross-piece, to which the whiflle or single tree 5 5 B may be attached. This singletree may comprise two members or sections pivoted or hinged at their inner ends to a union or journal piece B on opposite sides thereof and in such manner that their outer ends may fold or be drawn forward and inwardly. The j ournal or union piece may be of any suitable material and may have a plate I), attached to or formed integrally therewith, provided with one or more annular ribs or ledges 19, projecting downwardly therefrom and adapted to fit in an annular groove or grooves in a bearing piece or plate 12 which latter may be rigidly attached to the cross-bar by means of screws passing through lugs or flanges projecting 7o outwardly therefrom or in any other suitable manner. A bolt or stem 6 may depend or project from the plate 6, or may be secured to or formed integrally with the journal or union piece, and is adapted to pass through an aperture in the cross-bar A to assist in guiding the union-piece while oscillating or rotating in the bearing piece or plate 5 At b are projections or lugs extending outwardly from the union or journal piece on opposite sides thereof, preferably at its forward portion, and forming a recess in which a tongue or projection formed by recessing a portion of the socket-piece B is adapted to fit, said lugs or project-ionsof the union and socket pieces being provided with apertures through which a bolt or pintle b may pass, so as to hinge or pivot the union and socket pieces together. The socket-pieces may have their inner ends at the rear of the hinged or pivoting point thereof adapted to abut and bear against the outer sides of the union-piece when in its normal position in order to form a firm and suitable bearing-surface therefor. Each socket-piece may have a recess in its 5 outer end, in which is fitted and rigidly secured by a bolt or'otherwise a wooden bar I), the socket-pieces and bars forming the members or sections of the singletree, to the outer end of which the traces may be attached.

For the purpose of rigidly holding the members or sections of the singletree in position for moving the vehicle and to permit the outer ends of said members to fold or move inwardly I preferably provide a catch 0, having projecting outer ends forming lips 0, adapted to fit into recessed portions of the socketpieees l3 and engage projections or lugs c thereon, so as to rigidly hold the members of the singletree in their normal position when thus engaged. This catch may fit loosely upon a bolt (I, so as to tilt or rock slightly in a horizontal plane, and said bolt may have its body portion passed through an aperture in the union or journal piece B, said unionpiece being preferably provided with a recess d, Fig. 3, in which the head of the bolt may readily slide, the other end of the bolt being preferably polygonal and fitting similarlyformed apertures in said union-piece and catch and may be provided with a pin or projecting portion in its end to prevent the catch from slipping off orbeing removed therefrom. An eye (Z may be secured to or formed integrally with the catch or latch C, to which the end of a suitable connection or a strap (1 may be secured and which extends rearwardly to within convenient reach of the driver, so that by pulling said connection the catch will be disengaged from the projections on the socketpieees 13 though other means for releasingthe catch may be employed, if desired. Vithin the recess (1 of the union-piece may be arranged a spring (1 interposed between the head of the bolt (Z and the bottom of said recess in order that the catch may be automatically returned to its normal position when the strap or connection is released.

The bearing-piece I) may be provided with a suitable recess or opening 6, in which may fit a projection or lug c, projecting from the plate I) or from the union-piece, as desired. The recess or openinge is somewhat larger than the lug or projection c in order that the rotary or oscillatory movement of the unionpiece may be limited, though it is obvious that the opening or slot may be formed in the plate I) or in the union-piece and the projecjection 6 arranged upon the bearing-piece 11 By this means the usual straps for limiting the movement of the singletree may be dispensed with.

In order that the traces may be held upon the outer ends of the bars I), I may provide a tongue F, pivoted, as at f, within a recess formed in said bars. The tongue F may have two arms f and f arranged at an angle to each other, (preferably substantially at right angles,) so that when the tongueis thrown or swung on its pivot to the position shown in Fig. 2 the ends of the traces may be readily slipped over the bars b and the arm of the tongue f and may engage the arm f and force the same to the position shown in Fig. 1. In this latter position the draft or pull of the traces will hold the arms f in the recesses and will efiectually prevent the removal or disengagement of the traces from the singletree; but when the catch 0 is released by pulling upon the connection 01 the draft of the traces will cause the bars 5 or the members of the singletree to fold inwardly, as shown in Fig. 2, and simultaneously therewith will exert a lateral pressure upon the arms f, so as to force the same to the position shown in Fig. 2, so that the traces will readily slip from the end of said bars or members.

A clevis G may be provided with apertures in its outer ends adapted to fit over the end of the bolt or stem b and a stem or bolt g, extending upwardly from the union-piece in aliuement with the bolt D to assist in holding said union-piece and cross-bar together. This clevis may be substantially U -shaped and may comprise two members having overlapping ends provided with slots or a series of apertures through which the bolt (1 may pass in order to secure various adjustments and to permit said clevis to fit various sizes of cross-bars and singletrees. An opening or slot g may be provided in the member g, adapted to serve as a guide for the connection or strap (1 The operation of the invention will be readily understood from the foregoing description when taken in connection with the accompanying drawings. Assuming the parts to be in the position shown in Fig. 1, it will be seen that if the strap or connection cl" be drawn or pulled upon by the driver or otherwise the catch 0 and the bolt (1 will be drawn rearward against the pressure of the spring d" and will disengage the ends of said catch from the projections c on the socket-pieces B The draft or pull of the traces upon the ends of the members or bars I) will tilt the latter on their pivots and cause the same to fold inwardly, as shown in Fig. 2. This movement of the bars will cause the traces to slip laterally thereon, so as to engage the arms f of the tongues F and throw the same to the position shown in this latter figure, so that the traces will automatically slip therefrom. 13y releasing the pull on the connection or strap d the catch C will be forced to its normal position by the action of the spring (1, and when the bars b are forced or thrown into the position shown in Fig. 1 the ends of said catch will engage the projections c and will rigidly hold the sections or members until the catch is again released. I thus provide simple, efficient, and inexpensive means whereby the traces may be automatically detached therefrom in case of a runaway, accident, or otherwise, and which will rigidly hold and retain the traces in their proper position when in use.

I may employ in connection with this device a holdback similar to that shown in my pending application filed as of even date herewith, wherein is shown means adapted to permit the breeching or quarter strap to be automatically released, thereby permitting the entire unhitching of the horse from the vehicle, so as to prevent its destruction or in jury thereto.

The invention is shown as applied to a singletree, but it is obvious that it may also be applied to double or triple trees.

It will be readily understood that any suitable material may be employed for the several parts and that various changes may be made, or that some of the parts may be dis pensed with and others substituted therefor without departing from the spirit of my invention.
