JACOB B. GOLDSMITH, OF ROOKPORT, MASSACHUSETTS.

IMPROVEMENT 1N HoLDBAcKs.

Specification forming part of Letters Patent No. 158.370, date-d January 5, 1875; application led July 16, 1874.

To all whom t may concern:

Be it known that I, J Aeon B. GoLDsMITH, of Rockport, in the county of Essex and State ot' Massachusetts, have invented an Improved Holdback Iron for Carriage Shafts, and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specication, is a description of my invention sufficient to enable those skilled in the art to practice it.

The invention relates to holdback irons or hooks for carriage-shafts; and consists in the special construction hereinafter particularly described.

The drawing represents a shaft-iron embodying the invention.

Figures l and 2 show the construction in side and sectional elevation. Fig. 3 shows the construction in plan.

c denotes the main plate or bar, having at its front end a hole, b, through which passes a screw that enters the shaft, and at its rear end a vertical screw-shank, c, that passes through the shaft, and is permanently secured to the shaft by a suitable uut on the shank under the shaft. The bar is slotted, as seen at d, and in said slot is a strong horizontal spring, e, supported at its opposite ends on shoulders f. Over the screw-shank is an arm, g, that extends up from the bar, and then bends over into horizontal position, as seen in the drawing. The bar a is made with vertical ears h, in which are supported gudgeonplus t', extending from a lever, 7c, having rightangular arms lm. The arm l has, at its top,

an eye, n, that swings over the point of the stationary arm g. TheV lever 7c is held in normal position by the spring e and the pressure against it of a block-rubber spring, o. When the strap is to be inserted the arm Z is thrown down to the shaft. Then, by drawing the strap against the arm m, it is left inclosed between the arm g and the arm l. The spring holds the lever with sutlicient firmness in position to keep the holdback-strap from slipping out, but, if the traces break, the holdback-strap will bear against the lever-arm l, freeing the horse from the carriage. Extend ing back from the stationary arm g is a brace, p, having a hole, q, through which a screw passes into the shaft. By the brace p, the screws passing through the holes p q, and the screw-threaded shank-piece secured by the nut, the holdback-iron is securely fastened in position, and is also made very enduring in its own construction.

I claim- The holdbaek-iron formed of the bar a., having the screw-shank c, arm g, brace p, and having pivoted to the bar a the lever k, provided with an eye, u, in one of its arms, all combined substantially as shown and described. i
