Beit known that I, 'WILLIAM BLAISDELmof Port Byron, in the county of Cayuga, and State of New York, have inventcd-certain'new and useful Improvements in Shafts for Vehicles; and-I do'hercby declare that the following is a full, clear, and exact description thereoflfrefer'ence being had to the accompanying drawings, and to theletters of reference marked thereon, which form 'a part of this specificatiom in which- Figure 1 representsa plan view of my improved shaft-fastening fo'r vehicles, and Figure 2 a longitudinal section of the same. 7 The object of my invention is to provide a convenient fastening for attaching the-shafts of vehicles to the cross-bar; and'to this end my improvements consist, v

First, providing a hollow foot, of suitable form, which unites the shafts and cross-bar.

Second, in combining asprin'g and shoe-in the interior of this foot, with the hook to which the trace is attached, in su'chma'nner as to afford a ready ineansof connecting or disconnecting the latter. p I

In the accompanying. drawings, A represents a portion of the shaft of a vehicle, and a portion of the cross-bar. is a hollow casting or foot, of iron .or other metal, which has the shaft A bolted to one end of it, and the cross-bar C to the other. D represents thehook to which the trace is -fastened. This hook passes through an opening in the side of the foot, to the interior thereof, and has secured upon its inner'end a shoe, E,.in which it turns for a'portion of a revolution, being governed in its movement hy projections, e-, upon it, which strike against-a similar projection on the shoe.' A plate-spring,- F, is riveted on the inside of the foot, near the junction of the shaft, and has upon its other end a slot, through which a projection, E, on the shoe, passes. The end of this projection and the'surface of the springarc curved where they meet cachother, for

greater ease in working. The outer end oithe hook hears against a nose, D, on the outer end of the foot. The spiral spring (2 brings the hook 'back to position when it is turned in the shoe E.

To connectthe trace to the hook-D, thelhook isdrawn out in the direction of the arrow, and turnedinthe shoe, whiehremoves it from the projecting nosed), andallows the ring of the trace to he slipped into it. When I this is done the spring F draws it back, and the spiralspring e, fastened to the projectionE' of the shoe, turns the hook back to its original position. I v I Having thus fully described my improved shaft-fastening for vehicles, what I claim therein, and desire to secure by Letters Patent, is I l 1. The hollow foot 13, of iron or'other metal, when arranged as described, for the purpose of uniting the shaft and cross-bar. v

2. The combination of tho hook D and shoe E, with the springs candE and foot B, all arranged and operaring substantially as described for the purpose set forth. p

In testimony that I claim the foregoing as my own, I afiix my signature in prcsence of two witnesses. V WILLIAM'L. BLAISDELL. Witnesses:
