HENRY BUGKWALTER, OF KIMBERTON, PENNSYLVANIA.

IMPROVED CH ERRY-STON ER.

Specification forming part of Letters Patent No. 40,604, dated kdovember 17, 1563.

To all "whom it may concern: l

Be it known that I, H. BUGKWALTER, of -Kimberton, in the county of Chester and State of Pennsylvania, have invented a new and Improved Cherry-Stoner; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a a part of this specification, in which- Figure l represents a transverse vertical section of my invention, the linex x, Fig. 2, indicating the plane of section. Fig. 2 is a plan or top view ot' the same. Fig. 3 is a perspective view of the hopper.

Similar letters of reference in the several views indicate corresponding parts.

This invention consists in the arrangement ot' a rotary disk, with curved ribs, in combination with an adjustable hopper and a grooved channel, in such a manner that by the action of the curved ribs on the edges of the hopper and. channel the stones are squeezed out and caused to escape sidewise through said channel, and the pulp is deposited in a suitable vessel or reservoir below.

To enable those skilled in the art to make and use my invention, I will proceed to describe it.

A represents a frame, made of east iron or any other suitable material, and suppoited by three or more legs, B. This frame forms the bearings for a shaft, G, to which a rotary motion is imparted by a crank, D, or in any other suitable manner. y

E is a flat disk, made ot1 cast-iron or any other suitable material, and mounted on the This disk is provided on its face With a series of ribs, a, curved, as clearly shown in Fig. l, and by the action of these ribs on the cherries the stones are disengaged from the pulp. The cherries are introduced through a hopper, F, which is secured to the top of the frame A, in front of the disk E, by means of a set-screw, b. This setscreW passes through a hole or slot, c', in the bottom plate of the hopper, and said hole or slot is so arranged that on releasing the setscreW the hopper can be moved toward or from the disk and adjusted according to the size ot' the cherries to be stoned.

G is a side channel through which the stones are discharged. This channel extends from the bottom ot' the hopper, and its bottom edge,

inner surface of the channel and the face of the disk, and if the groove e is not in said innersurface of the channel each stone so turned clogs the machine. The groove e is so arranged that a small shoulder,f, isI left between its lower edge and the bottom ot' the channel, so that stones rolling on theirsmallest diameters are not liable to escape the action of the ribs and to remain stationary Within the channel. Without this shoulder such stones which are not turned up on their large diameters would not continue to roll in. the channel, and the separation of the pulp from the stone would not be completed. Imperfect cherries pass through this machine without having the pulp separated from the stones and the stones and imperfect cherries drop down from the channel G on the chute H and are discharged into asuitable vessel on the side ofthe machine.

This machine is very simple in its construction. Nearly allitsparts can be cast, and they require very little iitti'ng. T hey are not liable to get out ot' order, and the entire mechanism is easily operated.

What I claim as new, and desire to secure by Letters Patent, is-

1. The rotary disk E, with curved ribs a, in combination with an adjustable hopper, F, and

side channel, Gr, constructed and operating as and for the purpose shown and described.

2. The arrangementof the shoulder or offset d, groove e, and shoulderfin the channel G, to operate in combination with the rotary ribbed disk E, substantially as and for the purpose specified.

I HENRY BUCKWALTER.
