Be'it known that I, vWILLIAM D. ARNETT,

of Denver, in the county of Arapahoe' and S tate-of Colorado, haveinvented certain Ini- My invention has reference to that class of I graindrills and seeding-machines in which the "seed isdelivered'in a continuous stream from a feed-cup by means of an internal fluted or corrugated roll revolving therein; and it re la tes, first, to an improved arrangement of gearing whereby the speed of the distributer-roll maybe increased or diminished at will, and,

second, to an improved form and arrangement I of a feed-controlling gate by which the size of the delivery-opening may be modified withing to the driving-gear.and'distributing deresents a longitudinal vertical section through the frame of a machine provided with my improvements, the parts foreign to the invention being omitted. Fig; 2 is a front elevation of the distributer-driving gear. Fig. 3 is a vertical cross-section through the distributer on the line 00 a: of Fig. 4. Fig. 4 is a rear elevation of one of the distributer-cups.

. Referring to the drawings, A represents the customarymain frame of the machine; B, one of its ground-wheels; O, the main axle, by which the ground-wheels are carried; D, the usual hopper or grain-box, mounted on the frame; E, the distributer-shaft, extending longitudinally beneath the hopper; F, the feeddistributers.

The first part of my invention has reference to the means for imparting a variable motion from the main axle O to the distributer-shaft E, and is plainly illustrated in Figs. 1 and 2, in which G represents a cone-gear or a series of spur-gears, of different diameters, secured rigidly to the shaft side by side.

I represents a spur gear-wheel fixed on the I distribnter-shaft,its face having a to thatof thecone-gear. I I j I- represents an intermediate Q pinion,j by'j5'5 which motion' 'is transmitted frointhecohe-t gear to geanH. This pinion is movabl'e'l erally, so thatlit may engagewith either oftli several seriesof teeth on the cone geafllin der to transmita high or a low speedftoft e gear'H and thedistributer-shaft, asocca on, may require. 7 This intermediate'pinion is ried by arms on asleeve, .T,-wh'ich'latte1fi ranged to slide on anoblique rod or guide,,Kj,f1 mounted between the arms of agbifnrcate'd 1 handlever, L, the arms'of which are sustained; on or, around the axle O. Thism'odeiof' us tainingthe intermediate'pinion ad'mitso being shifted laterally for engagement fw one portionor another of the cone-g'ea maybe required. In order to hold the handlever in ipos'i'ti' and thus keep the pinion Ifin engagement provide a rack or locking-plate, Mifixedj ohf the hopper or other part of "the machine and'7 5 adapted to engage the lever, as shown. I The essence of my invention resides in combining with the cone-gear and the plain gear the intermediate pinions and a lever for adjusting the same, and it is manifest that the I details may be variously modified within the range of mechanical skill. I

Instead of having the gear H constructed with a broad. face, it may be arranged to slide endwise of the shaft, in order to retain its re-. lation to the pinion I as the latter is moved laterally. 1

Passing, now, to the second part of. my invention, attention is directed to Figs. 3and 4, in which or represents the feed-cup, secured to go the under side of the hopper, as usual, its top being open to receive the seed and its rear wall being provided with a delivery-opening, a. The horizontal longitudinally-fluted feedroll is arranged to revolve, as usual, within 5. the feed cup or case a, provided with a seed: delivery opening, a, at its rear side.

, I provide on the rear side of the feed-cup a transversely-sliding gate, N,-supported by lips d, or other suitable .guides. formed, as shown, with an upright edge, e, which spans the feed-opening at one end, and with a horizontal edge, e, which extends across the lower side of the feed-opening. When the The gate is ICOIV seed at the maximum rate.

gate is moved-to the right, the feed-opening is fully exposed and the device delivers the When, however, the gate is moved to the left, its vertical edge e diminishes the width of the feed-opening and the rate'of delivery is correspondingly less-" ened.

The lower edge of the gate is made of curved I or angular form, as plainly shown in Fig. 4,

form the lower edge of the delivery-orifice in an inclined position, so that one rib of the feed-roll will commence to discharge before the next rib ceases its action, by which the delivery is rendered continuous instead of intermittent.

' By constructing the gate so that the angle of the edge e is changed as the gate opens and closes I secure the extension of the edge across the rib, although the opening may be materially reduced in width. Thus I am enabled to secure all the advantages of the oblique edge under all adjustments of the gate.

The essence of my invention consists in arranging the gate so that the edge which forms the lower wall of the delivery-opening will change its vertical angle as it is opened and closed, and it is manifest that the gate may be modified in form and the guiding and supporting devices modified at will provided this action is retained.

The machine will be provided, as usual, with a series of distributers arranged at suitable distances apart, and in order to operate their 0 a suitable adj usting-lever or other equivalent 4 5 adjusting devices.

Having thus described my invention, what I claim is- 1. In a seeding-machine, the main axle and the cone-gear fastened thereon, in combination with the seeder-shaft and the elongated eylindrical gear thereon, the intermediate pinion, I, and the lever L, provided with an oblique guide, K, having a pinion-support arranged to slide thereon.

2. In combination with the feed-cup and the fluted distributer-roll therein,the transverselysliding gate N, forming the lower edge and one end of the delivery-orifice and adapted to change its angle in moving to and fro, as described, whereby the lower edge of the orifice is given an increasing obliquity as its width is diminished, and vice versa.

3. The feed-cup and the fluted distributerroll therein, in combination with the angular transversely-sliding gate N, having its edges e and e substantially as described.

In testimony whereof I hereunto set my hand, this 11th day of May, 1887, in the presence of two attesting witnesses.
