HOLDBACK FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 470,834, dated March 15, 1892.

Application filed June 10, 1891- Serial No. 395,797. (No model.)

To aZZ whom it may concern.-

Be it known that 1, ROBERT E. DANIELS, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented'certain new and useful Improvements in Holdbacks for Vehicles; and I do hereby declare the following to be afull, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates'to holdbacks used on buggy and carriage shafts or thills for connectin g thereto the quarter or holdback straps that extend from the harness; and its object is a holdback of such construction that it is readily adjustable to any part of the shaft, that-in use all backward stress upon it is converted into force that still more firmly holds it in place, and that in case the horse in mo tion accidentally becomes detached from the whiffietree it automatically uncloses, freeing the horse from the shafts, thus providing a holdback of great value for its superior convenience and safety in the use of all singlehorse vehicles. To accomplish this, I proceed upon the idea of a steel band surrounding the shaft, opened upon the under side, and provided in the form and function of the part to which the quarter-strap is attached with a means by which all backward pull upon this part serves to draw the band still more tightly around the shaft, while a forward movement of the same part loosens it altogether.

Figure 1 is a plan of a section of a buggythill with my holdback in place thereon. 'Fig. 2 is a face view of the key K. Fig. 3 is an edge View of the band B, and Fig. 4 is a modifica tion of the same.

The band B is a band of spring-steel of suitable thickness and breadth and of proper dimensions to pass around the shaft snugly but movably, opened at its lowest point by a cut at right angles with the edges and having each edge made by such cut similarly turned up and over by a line on an acute angle to the rearward edge of the band, forming the converging apertures a a for the passage of the key K. For appearance I japan ornickelplate this band,as I also do the exposed part of the key. The key K is a flat piece of steel of suitable thickness and breadth, having at its rear end the eye e, presenting a straight rear line and extending bya diminished and inwardly-curving prolongation to a part of a breadth that is suitable for the purpose, and

apertures a a of the band B are drawn toward each other, tightening the clasp of the band B upon the shaft S, while the-reverse movement will produce the reverse result. A connection between the ends of the branchesis maintained to keep the band and thekey from becoming disconnected. When in place the branches of the key K are directly against the central lower portion of the shaft S and longitudinal with it, while the eye 6, by reason of the curvature mentioned, appears upon the inner side of the shaft S at aconvenient point for attaching the quarter-strap. It is apparent that the same result in tightening and loosening the clasp of the band B may be obtained by forming the apertures a a on the lower instead of the upper side of the band B, as illustrated at Fig. 2, and also by making the angles of the apertures a a divergent from each other and forming the branches of the key K to correspond. Each of these would be the mechanical equivalent of the forms described, and I claim these and all similar variations to be within the spirit of my invention.

My invention will now be fully understood and its value appreciated for the purpose stated. The band B may by pressing forward the key K to loosen it be located quickly and easily at any point desired on the shaft, and when in place the firmness of its clasp upon the shaft is increased by the backward pull received from the quarter-strap, while the forward pull that would occur if the horse became otherwise detached from the vehicle would open the clasp, permitting the horse to escape, and thereby avoiding harmful results.

\Vhat I claim is- In holdbacks for single-horse vehicles, the adjustable safety holdback consisting, in comhination, of the band B, open 011 its lower side and presenting the convergent longitudinal apertures a a, and the key K, provided at one end with the eye 6 and at the opposite end 1 o with converging branches,and the mechanical equivalents of said parts, substantially as described in the foregoing specification, and for the purposes therein expressed.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses.

ROBERT DANIELS. \Vitnesses:

JAMES KENNEDY, J AS. HINEY.
