DRILL.

SPECIFICATION forming part of Reissued Letters Patent No. 9,969, dated December 1 3, 1881. Original No. 95,607, dated October 5, 1869. Application for reissue filed August 24, 1881.

To all whom it may concern: Be it known that we,J.R. RUDE, S. B. RUDE, and G. W. RUDE, of Liberty, in the county of Union and State of Indiana, have invented certain new and useful Improvements in Grain- Drills; and we do hereby declare the following is a full,-clear, and exact description of the invention,'that will enable others skilled in the art to which it appertains to make and use the, same, reference being had to the accompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to that class of graindrills in which the triangular-shaped frame is supported at the front end by a pilot or driving wheel and guided by an operator from behind grasping the handles of the machine.

Our invention consists in the combination, in a grain-drill, of seed-cups secured to the bottom of a seed-hopper under the respective seedopenings, and arranged between the bottom of the hopper and thecentral beam, and adjustable side beams or wings provided with seed connecting-tubes or conductors.

Our invention further consists in the combination of seed-cups secured to the bottom of a seed-hopper under the respective seed-openin gs, and movable or self-adjustable seed connecting-tubes or conductors, attached to the seed-cups so as to hang below the bottom of the seed-cups and between the central beam and the adjustable side beams or wings, whereby the seed-conduclors will automatically accommodate themselves to the adjustment of the side beams or wings.

Our invention further consists in the combination, in a grairrdrill, of acenter beam with a drivingwheel, adjustable side beams or wings, a seed-hopper, and seed-cups with seedwheels and movable orself-adjustable seed connecting-tubes or conductors.

Our invention further consists in the combination, with a seed-cup having at its base aslot, of a seedconductor having a journal-pin or pivot at its upper end working in the slot, whereby the conductor is capable of forward and backward movements.

Our invention further consists in the novel construction of a seed-wheel having its shaft bearing in the center thereof.

Our invention further consists in the combination of the seed cases or cups, the distributin g seed-wheels, and the operating mechanism.

Our invention further consists inthe novel construction and combination of parts, as will be hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 represents a central longitudinal sectional view of our machine. Fig. 2 is an end view of the same. Fig. 3 is a perspective view of one of the feedwheels. Fig. 4. is a detached view of the gearing; and Fig. 5 is a front view, in perspective, of the machine.

In the drawings, the letter A represents the central beam of the machine, formed with a longitudinal slot at its front end for the reception of the driving-wheel'H. The shaft of this driving-wheel is supported by means ofjournalboxes attached to the upper surface ofthe beam. To the front end of the beam A, and in the slot thereof, is secured an upright or bar, D, with a plurality of perforations for the drawhook at, to which the horse is attached; and t0 the rear end of the beam A is attached the bifurcated brace g, which serves as means for attaching and supporting the handles 0 C of the grain-drill, as seen in Fig. 2 of the drawin gs.

The letter B designates the side beams, hinged to the central beam, near the front end of the latter, and on opposite sides, at an acute angle, so as to form side wings to the central beam. These side beams, hinged to the central beam at their front ends, are provided at their rear ends with twojointed levers,ff, to which the vertical rod 6 is attached by means of the crank-arm, for expanding or contracting the side beams to suit rows of difterent width. This rod 6 is supported vertically by passing through the rear end of the beam A and through the cross bracebar s of the bifurcated brace g, and the upper end thereof is provided with a handle, 6, which engages with a notched segment, 0, arranged between the handles (3 0, serving to secure the handle and consequently the side beams in their adjusted position.

The letter F represents the seed-box resting on the supports or posts G G, secured to the cross-bar R, which is rigidly attached to the I00 central beam. This cross-bar R is slotted at its ends, through which the bolts 2, attached to the side beams or wings, B B, pass, and the beams are confined thereto by nuts. The office of these slots in the ends of the cross-bar is to allow thehinged or pivoted side beams or wings to be adjusted outward or inward, as may be desired, without detaching the seed-conducting tubes V, the construction of which will be hereinafter described. The seed-box F has a series of openings at the bottom for the issue of the seed, and to the bottom of the seed-box, over these openings, (see Figs. 1 and 2,) are secured the seed cups or cases i, with rear discharge orifices or openings, m.

The letter n represents the feed-wheels arranged within the seed-cups. Each of these feed-wheels (see Fig.3) is constructed with a square central bearing, so as to come in the center of the wheel, and the periphery is formed with alternating broken cogs constituting the seed feed surface.

The letter h represents a horizontal shaft passed through the seed-cups and the feedwheels n located therein. It is plain from an examination of Figs. 1 and 2 of the drawings that the feed-wheels a, penetrated and revolved by the shaft h, and working in the seedcups and directly under the openings in the seed-box, serve to discharge the seed from the seed-cups through the dischargesorifices m in the rear wall of the seed-cups. The lower ends of the seed-cups, (see Fig. 1,) below the floor of the cup, are formed with slots extending in the direction of the length of the machine to receive the pivots z of the seed-conductors.

The letter Y represents the seed conductors or connecting-tubes, enlarged or expanded at their upper ends, and provided with pivots 2, working in the slots at the base of the seedc'ups, substantially as seen in Fig. 1 of the drawings. The lower ends of these tubes fit easily and loosely within the hollow bulbs 0, connected to the upper surfaces of the side beams or wings over the drills r, substantially as seen in Figs. 1 and 2 of the drawings.

The letter Y represents the central seed conductor or connecting-tube, constructed similarly to the tubes V, and forms a communication with the drill r, as seen in Fig. 1 of the drawings. This construction of the seedconducting tubes will permit them to conform to the adjustment of the side wings and catch the grain as discharged from the seed-cups and conduct it to the drills for the furrows.

The drills r r, with hoes or shovels attached,

are braced to their connecting-beams by means of the curved rods 00, and these drills are made concave on their rear side to afford a safe passage of the seed into the furrow.

The letter m represents a countershaft, which works in two hangers, 0 0, beneath the seed-box F, and these hangers 0 o are slotted, so that the gearing of the two wheels 19 andj on the shaft m may be properly adjusted. The wheel j, it will be observed, gears into the spurwheel 10 on the shaft h, and thus operates the feed-wheels a.

To the projecting end of the axle H the sprocket wheel N is secured, and to the counter-shaft m a similar sprocketwhcel, k, is attached.

The letterLrepreseuts a chain which passes over the sprocket-wheels N and k, and thus motion is imparted to the shaft m and shaft h, on which the feed-wheels n are secured.

The sprocket-wheel It may be made to dis= connect the gearing by means of the lever t.

The letters a u represent two rods extending from the outer ends of the seed-box to the front end'of the beam A, as braces.

The operation of our machine is as follows: As the machine is moved forward the pilot or driving-wheel imparts motion to the shaft h, carrying the feed-wheels, through the agency of the chain and gearing, thus rotating the feed-wheels to discharge the seed out of the seed-cups through the discharge-orifices. The operator at the rear, as he guides the machine, can readily see the feed of all the cups, and detect if an obstruction should exist in any of the cups.

Having thus described our invention fully,

what we claim as new, and desire to secure by Letters Patent, is-- V 1. The combination, in a grain-drill, of seedcups attached to the bottom of a seed hopper or box under therespectiveseed-openingsthereof, and arranged between the bottom of the hopper and the central beam, and adjustable side beams or wings provided with seed connecting-tubes or conductors, establishing a communication with the seed-cups, substantially as described.

2. The combination, in a grain-drill, of seedcups attached to the bottom of a seed-box under the respective seed-openings, and movable orself-adj ustable seed connecting-tubes or conductors attached to the seed-cups, so as to hang below the bottom of the seed-cups and connected to the adjustable beams, whereby the seed connectingtubes will automatically accommodate themselves to the adjustment of the side beams, substantially as described.

3. The combination, in a grain-drill, of seed= cups attached to the bottom of a seed-box under the respective seed-openings, rotating feedwheels arranged in the seed-cups, movable or self-adjusting seed connecting-tubes, and side adjustable beams, substantially as described.
