IMPROVEMENT. IN STONE-GATHERERS.

i Specification forming part of Letters Patent No. 129,76*?, dated July 23, i872.

Specification describing anew and Improved Machine for Picking up, Stones, invented by BENJAMIN E. (TUPPER, of Odessa, in the county of Iopia and State of Michigan.

The invention consists in a peculiar mode 0f combining rake-teethv and revolving arms so as to transfer stones from the surface of the ground to an endless carrier.

In the accompanying drawing, Figure 1 is `a plan view of `my improved machine, and

Fig. 2 is a longitudinal section elevation of the saine.

y Similar letters lof reference indicate corresponding parts.

A is a suitable truclcframe mounted on two large wheels, B, in front of the `center, transversely, and a caster-wheel, C, at the rear. D is a long standing -frame mounted at the upper end on the axis E, above the rear frame A, so as to oscillate on said axis. At the lower end of thisframe it is armed with strong, curved metal teeth I, adapted to run under the stones and gather them upon their upper sides; and above these teeth there is an endless carrier of angle-bars, K, and chains L,

, operated by a roller or drum, M, on the axisV E, and passing over an idle roller, N, at the lower end of said frame, which said carrier V receives the stones from the ingers, and carriesthem up land delivers them to the box O of a truck, P, hitched to the rear of frame, A. To insure the delivery of the stones froml the y ngers onto the carrier, arms Q are mounted on a sleeve, B, revolving on the axle T, in

such manner that the ends of said arms come against the stones when passing under the axle, and in such manner as to force them up along the fingers, or to aid in so doing. I prefer to'attach these arms to the sleeve R by the bars S, which are fast to thecollars U of said sleeve, so as to support said arms in such manner that they can be readily taken out to put in others, in case they break or wear out. The said arms mayscrew entirely4 through the said bars S into the sleeve R, if preferred, for connecting them more strongly than they would be by connecting to the said bars S only. In this example both these rotating arms and the carrier are operated by one of the wheels B, which is geared, by the shaft 4volve between said teeth, as and for the purposes described.
