To [ZZZ whom it may coitceriz:

Be it known that 1, THEODORE 1). eat, of

Owego, county of Tioga, State of New York,

- have invented a new and useful Improvement in Grain-Drills, 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 an improvement in grain-drills, and more especially to that class in which a vertically-rotating feed-wheel with the side casing is employed, whereby the size of the feed-channel and the flow of the grain or other material contained in the hopper may be regulatedby simple and novel means; and it consists in providing the discharge-opening with a pivoted laterally-movable gate, in form intended to exactly correspond with and slide through an opening in the casing, said gate being hinged or pivoted, and provided with means whereby it is adapted to be rocked 011 its pivot, for a purpose hereinafter set forth.

In the accompanying drawings, Figure 1 represents a perspective view of so much of a grain-distributer as is necessary to show my improvements. Fig. 2 is a side elevation of the same; Fig. 3, a sectional view on the line as m, Fig. 2, and Fig. 4 a detail view, of the pivoted gate.

A represents a hopper of any ordinary or preferred form, to the base of which are secured the upper flanged ends, A, of the distributerwheel casing-plates. These ends A are secured to the hopper-box by means of lugs or projections a a, cast upon them, and extending upward at an angle corresponding with the inclination of the side walls of the hopper,

thro'ugh'which latter and the lugs referred to pass bolts for uniting the parts. The casing B is made in twoparts, forming a chamber for the reception of the vertical distributor-wheel O, as shown, the parts of said casing being connected by means of bolts 1) b at suitable points. A perforation, b, isprovided in one side of the casing B for the passage of the main shaft D, upon which the distributerwheel 0 is mounted. Other bearings for said shaft are provided in the form of pendent perforated projections A cast upon or secured to the sides of the hopper A. The shaft D is grooved its entire length, and the distributerwheel 0, where said shaft passes through it,

is provided with a small projection or key en terin'g said groove, thus serving to key the wheel to the shaft and insureits rotation therewith, at the'same time adapting the shaft tobe readilymoved when desired. The dis.

tribnter-wheel O is of the form shown in section in Fig. 3tl1at is, it is provided with a U-shaped annular groove, 0, forming achannel for the passage of the grain, and it also has an annular flange, c, surrounding its periphery, which is confined within and has its bearing against and between the side walls of easing B. An opening, B, is provided in the casing B, to one side of the center of wheel 0, immediately at the mouth of a cup or tube, E, through which the grain, as it is delivered from the wheel,'is conducted to the ground. Another opening or slot, in the form of an arc of a circle, (designated by F,) is provided in the casing, preferably below the center of the wheel 0, and a gate (shown in detail in Fi 4) is provided, adapted, when applied to said opening, to nearly iill the same. It consists of a piece, G, substantially of wedge shape, but, more accurately speaking, of such shape as to conform to the curvature of the groove 0 when it is inserted in the slot F. This wedgeshaped gate G has in rear of it a bar, G, to

which it is secured, said bar being provided on one end with a shank, g, which enters a socket, g", in the wall of the tube or cup E, and at its other end with a tooth or point, 9, adapted to be engaged by a worm or a screw, H, formed upon a shaft, H, supported in suit able bearings provided for that purpose. The bar G is supported at one end in the socket g" and at the other in a slotted cross-bar, I, just beyond which slot the tooth or point g is engaged by the worm or screw H. The shaft H y is revolved by means of a crank, hand-wheel, or in any suitable manner, and when so revolved, the worm or screw H being formed upon it or secured to it, the outer end, 9, of the bar G, by means of its engagement with screw H, will be moved either toward or away from the casing B, carrying with it the gate, which serves to either decrease or increase the size of the channel 0 at that point. Thus, the size of the channel being adjustable, by means of the gate G, the flow 'of grain can be regu lated at will.

For insuring the passage of the grain in the channel 0 of the wheel 0, the walls of slid channel are roughened or provided with starts or indentations, as shown.

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

1. In a grain-drill, the combination, with a vertical distributing-wheel having a side groove or channel formed therein, of a laterally-swinging gate formed upon an arm pivoted outside of the distributing-wheel casing and adjustable transversely within and across said channel, for regulating the capacity of the channel, substantially as described.

2. In a grain-drill, the distributer-wheel casing provided with an orifice in its side, in combination with a laterally-swinging gate formed upon an arm pivoted outside of the distributing wheel casing and adjustable zo-through-said orifice transversely of the dismy hand.
