GEORGE W. Earlier, on BALTIMORE, MARYLAND.

CHERRY-SEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 255,874, dated April 4, 1882.

Application filed November 3, 1881. (Model) To all whom it may concern:

Be it known thatl, GEORGE W. KNAPP, a citizen of the United States, residing at Baltimore, in the county ofBaltimore and State of Maryland, have invented certain new and useful Improvements in Cherry-Seeding Machines, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to a machine for removing the seeds from cherries.

The construction and operation of a machine embodying my improvements will be first described, and the invention then designated in the claims.

Inthe drawings hereto annexed, Figure l is a side elevation of the machine, showing a portion broken away to expose the cylinder. Fig. 2 is a top view of the machine. Fig. 3 is a view of the cylinder in section, theseed-clearing wires, and the pluugers. Fig. 4 is also a sectional view of the cylinder, the wires, and theseed-remover. Fig. 5 is partly a side and partly a sectional view of the cylinder and wires. Fig.6 is a vertical cross-section of the cylinder and the endless apron. Fig. 7 is an end view of the cylinder and the brake device. Fig. 8 shows two views, enlarged, of the punches. i i

TheletterAdesignates the sides of the frame of the machine; B, the hopper to receive the cherries; G,the hollow cylindelyprovided with sockets, each adapted to receive a cherry.

D is the main shaft, andD the pulley by which it is driven. The sockets to on the outside of the cylinder are arranged in rows extending in straight lines lengthwise of the cylinder. Each end of the cylinder is turned down, as shownat b in Figs. 3 and 4, to form a journal, which rests and revolves in the bearings c in the sides of the frame. The ends of the hollow cylinder are open, and each projects somewhat from its bearings, one end being provided with ratchet-teeth d, (seen in Figs. 1 and 2,) and the other end serving as a face on which a brake device, as, may be applied. The dimensions of the sockets are such as to adapt them to receive a full-sized cherry, and from the bottom of each a hole, c, leads into the hollow cylinder, and through this hole the cherry-seed passes.

Two stationary bars, f f, extend across the machine from one side tothe other. The bars are perforated to allow the punches g to pass and slide through them, and all the punches are carried or moved by across-bar, E, which has a reciprocatingmovement between the two bars fand f. This bar is moved by a rod, h, at each end, which connects with a wrist-pin on the crank-head F, one crank headbeing mounted at each end of the shaft F, which extends across the machine and is driven by gearing 9 from the main shaft.

A bracket, G, is secured to the side of the frame, and to the bracket an arm, 0, is pivoted. This arm carries a pawl, 'i, which engages with the ratchet d on the endof the cylinder, and a vibrating motion is imparted to the arm by the rod J, which connects with a wrist-pin on a plate, K, which plateis attached to the wristpin on the crank-head F, to which latter wristpin'the rod h is connected; Thus the one crankhead gives motion to two rods, h and J.

By the arm and pawl mechanism just described intermittent movement is given to the cylinder.

To prevent the cherries in the hopper from beingcrushed by the revolving cylinder, an endless apron or belt, L, is provided, which constitutes practically one of the walls of the hopper. The belt passes over a roller, 1', whichextends across the hopper near the top and at one side, and over another roller, 8, which extends across the hopper at the bottom and in close proximity'to, if not in contact with, the revolving cylinder. A journal of the roller rpasses through the side of the hopper, and has attached a pulley, 1'', which is driven by a belt or cord, t, from the crankhead F. Each of the sockets in that portion of the revolving cylinder which is exposed in the bottom of the hopper receives a. cherry. The cylinder turns, as shown by the arrow, in a direction from the hopper toward the endless belt. Thus the tendency is for the cylinder to carry the cherries toward the belt. That side of the endless belt against which the cherries are carried by the cylinder, and which constitutes one of the walls of the hopper, has an upward movement, as shown by the arrow. The effect of this movement of the belt is to keepthe cherries which lie against the cyl- IOC inder, and which the latter tends to carry toward the belt, pressed back by such gentle means as not to injure them, and to prevent more than one cherry at a time from entering each ofthe sockets. The movement of the endless belt also prevents any cherries from being wound between the casing m and the cylinder, where they would be crushed. The casing m covers that portion of the cylinder between the hopper and the punches. As the hollow cylinder is open from one end to the other and has nothing to obstruct it internally, a stationary device to clear the seeds or stonesfrom the ends of the punches is arranged and extends lengthwise through the cylinder from end to end. This device to knock the seeds which adhere to the ends of the punches consists of two wires, u, stretched tightand having their ends secured to the arms G and G. When the punches, with a seed on the end of each punch, penetrate the holes 0 to the interior of the cylinder, they enter betweenthe two wires, which are thereby forced or spread apart, and upon the withdrawal of the punches the two wires resume their normal position or come together, and in doing so knock the seeds off.

The two wires to knock off the seeds are not onlyoperative in connection with the mechanism shown-to wit, a hollow cylinder provided with sockets having holes and reciprocating punches to enter the holesbut it is obvious the two wires would also effect the same result with sockets having holes regardless of their being arranged in a hollow cylinder and reciprocating punches to penetrate the holes.

A shaft,v, has its bearings in the two arms G and G and extends through the hollow cylinder. A spiral flange, w, is wound on this shaft and is in contact with the interior bottom of the cylinder. The end of the shaft is provided with a. pulley, o, and motion is given .to the same by a belt passing over the pulley and also over the pulley s. This spiral device, by its arrangement in contact with the interior bottom of the cylinder, serves, first, to scrape the interior surface of the cylinder, and thereby remove any seeds which may adhere thereto, and, second, to carry the seeds out of the cylinder.

v The shape of the punches is shown in Fig. 8. The ends are barbed on two opposite sides. The barbs, being in the horizontal direction,permit .the end of the punchto enter between and withdraw from the wires, which are stretched horizontally. The barb on the punch serves to draw the cherry out ofits socket after the punch has punched out the seed, and as the barbed end is drawn through the slide-hole in the stationary barf the cherries are stripped from the barbed ends and drop in a pan below, as seen in Fig. 1.

The brake 00 consists of two semicircular j aws, each pivoted. 3 "an extension, y, to the side of the frame, and serves tohold the cylinderfrom turning while the arm 0 and pawli move back.

The operation, briefly stated, is as follows Assuming the hopper contains cherries and the machine is in motion, each socket in the cylinder which is exposed in the hopper receives a cherry. The endless beltor apron prevents the cherries from being crushed between the easing, which partly covers the cylinder, and the cylinder. Thepunchesdrivetheseedsthrough the holes in the sockets. The two wires remove the seed which adheres to the end of each punch. The spiral flange carries the seeds out of the cylinder. The ends of the punches, bein gbarbed, serve to withdraw the cherries from the sockets, and by the barbed part of the punches being drawn through the slide-holes in the bar the cherries are stripped therefrom I and drop into a receptacle.

It is not essential, in order to use the several features which constitute my invention, thatall the parts shall beconstructed as herein shown, nor that all the parts shown shall be used.

Having described my invention, 1 claim and desire to secure by Letters Patent of the United States- 1. In a cherry-seeder, the combination of a cylinder adapted to revolve and, having sockets, each of which are to receive a cherry, a hopper from which the cherries are fed to the cylinder,and an endless belt or apron mounted in the hopperiu proximily to the cylinder and constituting one of the walls of the hopper, as and for the purpose set forth.

2. In a cherry-seeder, the combination of a hollow cylinder adapted to revolve and provided with sockets to receive cherries, punches to reciprocate and arranged forthe end of each punch to enter a socket, and two wires stretched through the cylinder and arranged to permit the ends of the punches to enter between the wires, as set forth.

3. In a machine for seeding cherries, the construction herein set forth, consisting of a hollow cylinder provided with holes leading into the cylinder for the passage thereinto of the seeds, and a shaft extending through the cylinder, having a spiral flange arranged to revolve in contact with the interior surface of the cylinder at its bott01n,whereby the spiral flange serves both as a scraper and a seed-remover, as set forth.

In testimony whereofI affix my signature i presence of two witnesses.
