SPECIFICATION forming part of Letters Patent No. 419,683, dated January 21, 1890.

Application filed February 20, 1889. erial No. 300,630. (No model.)

To aZZ whom it may concern:

Be it known that I,W1LLIAM M. Korrns, a citizen of the United States, and a resident of Orrville, county of \Vayne, State of Ohio, have invented a new and useful Improvement in Thrashing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in thrashing-machines, more particularly to that class of machines known as vibrators; and it consists in providing improved means of operating the several parts and to reduce the initial cost.

With these ends in view my invention consists in certain features of construction and combination of parts, as hereinafter described, and set forth in the claims.

Figure 1 of the accompanying drawings is a view in perspective from left-hand front of a thrashing-machine, illustrating my invention; Fig. 2, an elevation showing right-hand side; Fig. 3, an elevation showing left-hand side; Fig. 4, a vertical longitudinal sectional view showing position of parts; Fig. 5, aview in perspective of vibrator-supports; Fig. 6, a

7 .similar view of vibrator-hanger; Fig. 7, a plan from below, showing under side of a portion of the machine; Fig. 8, a view comprising a hanger, vibrator-lever, and conneeting-link heads in perspective; Fig. 9, a view from rear, showing the end of. the. machine.

Similar letters of reference indicate corresponding parts in all of the figures of the drawings.

The frame of the machine is composed of stout horizontal sills A, vertical posts 13 B B and cross sills or girders O, the posts B and B projectedadistance below the sills A. The body portion of the machine is inclosed by sides and deck in the usual Way. The front end of said frame is secured to a bolster D, which rests upon an axle, as D, which is supported by carrying-wheels D The rear portion of the frame is secured to the axle D supported by carrying-wheels D The front portion of the frame is raised suflioiently high by the bolster D to allow the wheels D to be turned under the body of the machine, and to secure the bolster and machine in proper relation a reach, as D, is provided, having its front end secured to the bolster D andits rear end to a cross-girder D, secured to the lower portion of the posts B. A metal corner-plate D is provided, which serves to inclose a portion of the front end of the body of the machine, as shown, and to form a portion of the end of the cylinder-casing, in which a bearing an is located, through which the cylindershaft extends, the said corner-plate resting on and secured to that portion of the frame designated as A and B The thrashing-cylinder E may be of any of theWell-known and approved forms. It is supported on an arm a, the rear end of which is secured to the frame-post B and extending forward and inwardly, the front end secured to the corner-iron or cylinder-casing, substantially as shown. The said arm is further supported by the post a, the upper end of which is bifurcated, the prongs a secured to the arm a, one on each side of the cylinder-shaft, as shown. The lower end of the post is secured to the frame-sill A. v

The winnowing-wheel 71 is supported in a U-shaped frame h and inclosed in the usual way. On the end of the Wheel-shaft is provided a pulley adapted for a belt engagement with a driving-pulley, by which said wheel is rotated to produce the necessary blast to clean the thrashed grain.

It will be noticed that the thrashing-cylinder is shorter than the width of the separator and is housed separately and outside of the body of the machine, by which arrangement the separating capacity is enlarged to a point.

in excess of the thrashing capacity of the cylinder, thus assuring room to spread out the thrashed straw, and by such means, as will be hereinafter described, agitate the straw and cause the grain to fall therefrom to the graintable. In this case the vibrating table F is composed of a series of narrow troughs or tables F F having side boards as},b, l 1aving serrated upper edges, and fins, as h, intermediate their ends, as shown, the bottom board of I) having perforations 11 through which the thrashed grain may fall to the vibrating grain-table G. The front ends of the vibrators F are supported on an alternatelycranked shaft H, the rear ends supported von.

links I. The said link is made ofcast metal in form substantially as that shown in} Fig.

5, having two parallel pipe portions a in which pins of hard wood may be placed from time to time, as occasion may require, to form the journals 0..

The vibrating grain-table G is constructed as follows: The intervening space between the side boards D is inclosed or covered a distance from w to so by overlapping bottom boards of", forming steps or offsets a, that operate to move the grain rearwardly as the table is vibrated. In the rear portion of the bottom space, as froma: to 1 is placed a riddle a of unusual length, in order to provide a large fiddling-surface to allow of the use of a smaller mesh than has been heretofore used in this position and relation to a grain-table vibrated under a vibrating separator, and as it would be impractical to distribute or control the wind-blast from the ordinary windwheel used for such purposes over so large a surface as that of the riddle a I place in the shoe Z a grain-board a upon which the grain that passes through the meshes of the front part of the riddle from m to will fall upon the board a the vibratory movement of which will cause the grain to move rearward to the end of the board a at which point it will fall through the wind-blast from the winnowingwheel h to the return-board a", thence down into the conveying-spout U out of the machine. A wind-board, as a, is placed in the shoe, standing transversely to the direction of the wind, that may be turned to change the direction or deflect a portion of the windblast, as may be desired. It will be noticed that the board a has a double purpose, that of a grain-board'over which the grain is conveyed; but it also forms'with the return-board a a throat or passage-way by which the blast of wind is carried to a point central, or there-j about, to the riddle.

The grain-table G is supported on swinging hangers J, a stud-pin 11 secured to the table, resting in the journal-box b in the lower portion of the swinging arm J. The upper portion of the arm is provided with an inwardly-projected portion, forming a journal,

as b, which rests in a journal-box, as 12, sup- 1 The lower portion of i the arm J is provided with a square openended socket, which has an aperture, as 11 (see Fig. 6,) said aperture having fixed there- 1 in a block of hard wood having a perforation corresponding with a similar perforation Z2 in the said socket portion of the hanger, the said block forming the bearing for the studported on the sill A.

pin b*, on which the vibrating grain-table is supported. I prefer this form and construction of journal-box, as in it is provided an inexpensive renewable journal-box formed of hard wood, which I have found more desirable for'this service than metal. A worn-out block is easily removed, a new one driven into the iron frame, ant the journal-box formed by boring through the block with a proper-sized boring-bit.

The cranked shaft 11 has mounted on its left-hand end a pulley K, to have a belt engagement with a driving-pulley, as L, on the cylinder-shaft, and a pulley, as M, is also mounted on the shaft H. to drive other parts of the machine. 011 the right-hand end of shaft H there is mounted a crank-wheel P, to which one end of pitman Q is pivotally secured, as shown. The other end in a similar manner is secured to the upper portion of a vibrating lever B. Said lever is mounted 011 a cross-shaft S, supported in hanger, as (1, secured to the under side of the main sills A, the said lever B extending a distance below the shaft S, as shown in Fig. 2. On the opposite end of said shaft is mounted a crosshead T. A link, as d, is provided, one end of which is pivotally secured to the upper portion of the cross-head T, the other end to the side of the vibrator grain-table G, as shown at (Z Fig. 3, and a similar link d having one of its ends pivotally secured to the lower portion of the cross-head T and the other end to the side of a riddlesupporting shoe Z, as shown at (P, Fig. 3; and on the right-hand side of the machine similar links d and d are provided, link (1 having one end pivotally secured to the lever R at the point above the rock-shaft S, the other end secured to the side of the grain-table G, as shown at (Z and link (1 having one end pivotally secured to the lever below the shaft S, the other end secured to the shoe Z, as shown at d, an aperture having been made through the side boards of the machine to allow the ends of the links d d to pass through for engagement with the grain-board and shoe, as hereinafter stated.

The purpose and operation of the parts will be apparent. When the cylinder is in operation, motion will be communicated to shaft H, the cranked portions of which will give to the front ends of the vibrator-tables F alternately an upward and rearward, downward and forward, or rotary reciprocating movement, the rear ends of the tables being supported on and vibrated over the links I. The crankwheel P, operating the pitmaniQ, will vibrate the lever B to rock the shaft S, which movement willvibrate the links cld in pairs, the upper links 61 vibrating the grain-table G, the lower pair d vibrating the shoe Z. The driving centers may be varied, so as to give more or less throw to the vibrated parts of the machine. For instance, the distance of the crank-pin on the wheel P may be placed at different points between the periphery of the wheel and the shaft, or the other end of the pitman may be placed nearer to or farther from the shaft S on the lever B and the links 61' d placed at such a distance from the shaft S as will give the desired result. Preferably the links 1 are placed at a point nearer to the shaft, as the shoe and riddles should not be vibrated so great a distance .as the grain-table G. It will be apparent that a machine thus constructed may be operated with less power and be so adjusted as to run to vibrate the spouts longitudinally is pro-' yided, as shown in the drawings, especially in Fig. 7, which consists of a sway-bar XV, pivotally secured to an arm G (projected from the rear bolster D at one of its end portions, to which a crossbar is secured, forming arms d (Z projecting at right angles to the bar NV. The grain-spout U is connected with the arm (1 by the link (i and the spout V to the arm d by the link (1 and to operate the sway-bar W a link, as Y, is provided, one end of which is pivotally secured to the bar WV, the other end secured to the bottom of the shoe Z, the vibrations of which will carry the sway-bar WV forward and back, which movement will rotate the arms d (:1 about their pivotal connection with the arm 0, by means of which the spouts are vibrated transversely to the movement of the grain table and shoe.

It will be noticed that all of the machinery connected with and including the vibrating portions of the machine are secured to and supported on the heavy sills A. The advantage of this arrangement will be apparent, as not only weight but whatever jar there may be caused by the vibratory movements of the tables F and G and the shoe Z is sustained by the sill A.

The tailings deposited by the spoutV into the elevator-trunk N are carried up and forward to the cylinder in the usual way, and to prevent the cylinder throwing grain through the machine an apron, as O, is suspended from the deck, as shown in Fig. 4.
