THRASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 296,015, dated April 1, 188%.

Application tiled August 4,1883.

To all whom, it may concern Be it known that I, JOHN M. G. JONES, a citizen of the United States, residing at London, in the county of Madison and State of Ohio, have invented a new and useful 'lhrashing- Machine, of which the following is a speeilieation, reference being had to the accompanying drawings.

This invention relates t o t h rushingmachi nos and grain-separators; and it has for its object to produce a machine which shall possess superior advantages in point of simplicity and general efficiency.

To this end it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure l is a side view. l i 2 is longitudinal vertical sectional view. Fig. 3 is a top view, the top casing having been removed so as to expose the working parts; and Fig. 4 is a sidey'iew of the side opposite to the one shown in Fig. l of the drawings.

The same letters refer to the same parts in all the figures.

A in the drawings designates the frame of the machine. B is the cylinder, and C the concave, which are constructed and arrangtal in the usual manner.

Between the sides of the frame, in rear of and slightly above the cylinder 1 are bear ings for the shaft 1) of a cylinder, 1G, provided with teeth 1*, which are curved, as shown, and set in irregular or curved rows. This cylinder serves to loosen and scatter the straw as it comes from the concave and passes to the separating-table (t. The latter, which is hung or supported between the sides of the frame by hangers or stirrups ll, consists of a frame, I, the sides of which are connected by a series of inclined slats, J, between which the grain may pass onto the grain-table. J ournaled between the sides of the frame I are a pair of shafts, K K, having radial win or beaters L. When the said shafts revolve during the opcrat ion of the machine, as will be hereinafterdescribed, the wings or beatcrs serve to loosen the straw passing overtheseparating-table, so asto cause the grain to pass more readily between the slats forming the bottom of the same.

(No model.)

M M are shafts journaled transversclyinthc upper part of the frame, and having cranks N, connected by pivoted rods O, which connect the said shafts in pairs, as shown. Two of the said shafts have crank-arms P extending beyond the sides of the frame, and connected by pitmen Q with cranks 11 upon the ends of a shaft, S, journaled transversely in the frame below the front end of the separating-table, and serving to convey an oscillating motion to the shafts M. The latter are provided with curved arms or fingers T, that serve to pick and loosen the st raw as it passes over the separating-table.

The grain-table consists oftwo sections, U X", hung in stirrups \V, between the sides of the frame. The front section, U, terminates directly above the front end of the shoe, and the section V is inclined from the same point in an upward direction, so that it will also discharge at or near the front end of the shoe. The sections U and Y are connected by pivoted rods X, so that a vibrating motion conveyed to the section U will be communieat ed by the latter to section V.

Y is a shaft mounted transversely below the shaft S, which latterhas a gear-wheel, Z, meshing withagear-wheel, A, ofhalfthe diameter, upon the shalt 'Y. The latter is provided with cranks 1; and t", connected by pitmen l) and 111, respectively, with the separating-table (l, and with the section If of the grain-table, to which a rceilu'ocating or vibrating motion is thus imparted. The crankshaft Y is driven by a belt, 1", running over a pulley, (2, upon the cylinder-shaft, a pulley, ll, upon the shaft of the pieker-cy]indcr, a pulley, 1, upon the fan-shaft J, which is thus also driven, and a pulley, K, upon the end of the said shaft Y.

L designates the shoe, which is hung upon erankshafts M in rear of the fan-case. The rear end of the shoe has a deflector by means of which the blast may be regulated. One of the shafts, M, has a crank, 1, entering a link, Q, which connects one arm of a bellcrank lever, t, pivoted to the side of the cars ing, with the arm S of a collar, T, working upon an eccentric, ll, upon the fan-shaft. .liy this link-motion the stroke or movement of the shoe may be regulated according to whether the grain operated upon be dry or wet, and

therefore requiring to be more or less thoroughly shaken.

The beater-shafts K K extend through slots in the side of the casing, and are provided with pulleys V, connected by a belt or band, \V. One of the said shafts is also provided with a pulley, f, connected by a band, Y, with a pulley, Z, upon the end of the fan-shaft, from which motion is thus communicated to the boaters K.

The operation of thisinvention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. The picker-cylinder, the pickerarms, and the ,revolving heaters cooperate to thoroughly separate and loosen the straw, thus enabling the grain to pass freely from the separating to the grain table. The general construction of the machine is simple, and it is durable and eflicient.

I claim as my invention and desire to secure by Letters Patent of the United States 1. The combination of the separating-table, the shafts journaled transversely in the same, and having radial wings or beaters, one end of said shafts extending through the frame or casing of the machine, pulleys upon the said pro jecting ends, a belt or band connecting the said pulleys, and mechanism for conveying motion to one of the said. shafts from the fan-shaft, substantially as set forth.

2. In a thrashing-machine and separator, the combination of the separating-table having the bottom formed of inclined slats and pro vided with the revolving heaters, the revolving picker-cylinder and the vibrating pickers, all cooperating to loosen and separate the straw in its passage through the machine, substantially as set forth.

3. In a thrashing-machine and separator, the combination of the shoe mounted upon crankshafts, as described, a crank upon one of the said shafts extending beyond the side of the casing, an eccentric secured upon the fan-shaft, a collar working upon the said eccentric and having an, arm, a bell-crank lever pivoted to the side of the casing, and a link working upon the extending crank and connecting pivotally one arm of the bell-crank lever with the arm of the eccentric-collar, whereby the stroke or movement of the shoe may be regulated, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
