Be it known that I, CHARLES A. SMITH, a citizen of the United States, residing at Dresden, in the county of Yates and State of New York, have invented a new and useful Improvement in Thrashing-Machines, of which the following is a specification, reference being had to the accompanying drawings.

My invention has relation to improvements in thrashing-machines; and the novelty consists in the peculiar construction and combination of parts, substantially as hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a portion of athrashing machine and the shakingshoe thereof with my improvement applied thereto. Fig. 2 is a horizontal section on the line :r .r of Fig. 1.

Referring to the drawings,in which like letters of reference denote corresponding parts, A designates one of the side walls of a thrashing-machine; B, the lower rear shaking-shoe thereof, and O my improved regulating device to vary the stroke or movement of the shoe, and D the shaft that drives the shoe. This shaft D is driven by a belt or other suitable connection with the operative parts of the thrashing-machine, and for convenience it will hereinafter be. designated as the driving-shaft to the shoe B.

E designates a crank-wheel mounted on the shaft D, and having one of the arms thereof slotted, as at e, and through this slot passes a bolt or crank-pin, which serves to pivotally connect the outer end of a connecting-rod, F, thereto. This rod F passes through a slot, a, in the side wall, A, of the thrashing-machine, and is pivotally connected to an oscillating bar, G, which is pivoted at one end to a bearing or bracket, G, secured on the inner face of the wall A of theinclosing-casing of the thrashing-machine, the opposite end of said oscillating bar being arranged between the arms h h of a guide, H, also secured to the wall A.

I designates a cross-head arranged to slide back and forth on the oscillating bar G, and J designates a connecting or shake rod pivotally connected at its outer end to the sliding 5o cross-head I, and at its inner end to a plate,

3', which is rigidly secured to the shoe B near the middle of its longitudinal axis and outer It will thus be seen that when rod F the bar G will be oscillated back, and forth on its pivot, and that the cross-head I and shake'rod J, being connected to said oscillating bar G, will be operated ordriven thereby, and thus impart the requisite motion to the shoe B.

By adjusting the sliding cross-head near the outer free end of the oscillating bar G, and farther away from the pivot thereof, it is ob vious that a greater movement or a longer stroke is imparted or given to the shake-rod, and consequently to the shoe B; but when the sliding cross-head is moved toward or nearer tol the pivot of the oscillating bar a shorter stroke or movement is given to the shake-rod.

I will now proceed to describe the means for adjusting and holding the sliding crosshead in a fixed position on the oscillating bar.

K designates a rod pivotally connected at one end to the sliding cross-head I, and at its opposite end to an adjusting arm, L, which is preferably arranged at a right angle to the rod K, and projects or extends through a slot, a, in the wall A, and is provided with sleeves Z, which fit over an arm or bar, M, rigidly secured to the outer face of the side wall, A, of s the inclosing-case of the thrashing-machine. The adjusting-arm L may be provided with only one, or two, or more, sleeves Z, and each sleeve carries a thumb or adjusting screw or bolt, Z, which is adapted to bear or impinge against the bar M and hold the sleeve or sleeves rigidly thereto and prevent them from sliding or moving on the said rigid bar.

To adjust the sliding crosshead on the oscillating drivebar G, it is only necessary to loosen the set screw or screws l of the sleeves Z and move the same in the required direction. To give a greater shake or stroke to the shoe B, the sleeve or sleeves Z are adjusted on the bar M in the direction shown by the arrow in Fig. 2 ofthe drawings,so that the sliding crosshead is moved farther away from the pivot of the oscillating bar G and nearer the outer end thereof, and to impart a slight stroke or lighter shake to the shoe the sleeves are adjusted in the reverse direction to draw or move the cross-head nearer the pivoted end of the oscillating bar, at which end it has very little or no movement.

g I swam My improved regulating device can be applied and adapted for use upon any class or character of grain-separating, thrashing, or clover-hulling machines, when it is desirable to vary the stroke or movement of the shoe or shoes thereof. In order to adapt the device to machines of different kinds and characters, it may be necessary to change or alter the relative arrangement and form and proportions of parts, and I would have it understood that I hold myself at liberty to make such changes and alterations.

My improved regulating device is simple, strong, and durable in construction, can be adjusted while themachine is in motion with out stopping the same, can be applied very readily to ordinary thrashing-machines at a very small cost, and is thoroughly effective in operation and easy of adjustment.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a drivingshaft, an

oscillating bar actuated by the shaft, a cross head adjustable laterally with respect to the pivot of the bar, a shoe, a rod intermediate of the cross-head and shoe, a rigid holding-bar, an adjusting-arm having sleeves movable on the bar and adapted to be rigidly held thereon, and a link connecting the adjusting-arm and cross-head, substantially as described.

2. The combination of a shoe, a pivoted oscillating bar, a driving-shaft, a guide for the bar, asliding cross-head mounted thereon, a rod intermediate of the shoe and cross-head, an adjusting-arm carrying sleeves and setscrews, a bar on which the sleeves are secured, and a link connected to the cross-head and adj nsting-arm, substantially as described.

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

CHARLES A. SMITH.
