GRAIN-DRILL.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application fil d February 5, 1906. Serial No. 299,661.

To all whom it may concern:

Be it known that I, WVILLIAM FETZER, a citizen of the United States, residing at Mid.- dletown, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Grain-Drills, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an improvement in grain-drills, and more particularly to the mechanism utilized for lifting or depressing drills, furrow-openers, or hoes for such graindrills.

The invention comprehends a foot-board secured to the machine and extending transversely of the drills and means for lifting and depressing the drills, including a lever movable transversely of the machine and arranged to swing wholly in a plane at one side of the foot-board and within easy reach of an operator standing thereon, and in this respect has reference to the subject-matter disclosed in my application which resulted in the grant of Patent No. 752,618, dated February 16, 1904, and wherein the same is shown as a modified form.

In the drawings, wherein like letters of reference refer to similar parts in the several views and wherein a preferable embodiment of my invention is shown, Figure 1 is a vertical longitudinal section through my improved grain-drill. Fig. 2 is a horizontal section on line 2 2 of Fig. 1. Fig. 3 is a detail view showing the manner of securing the footboard hangers to the frame. Fig. 4 is a cross-section on line 3 3 of Fig. 1. Fig. 5 is a detail view in elevation of the operatinglever for controlling the height of the drills, and Fig. 6 is a cross-section on line 6 6 of Fig. 5.

Referring now more particularly to the drawings, the frame of my improved drill comprises the side pieces A A and the transverse connecting members B.

O designates the hopper for the grain, which extends transversely of the machine and has secured to the ends thereof castings 0, provided with downwardly-extending lugs or arms 0, which-are adapted to be secured by suitable clamping-bolts to the side pieces A A of the frame.

D designates the axle of the machine,which is supported in suitable bearings (Z, secured to the side pieces A A of the frame by suit able clamping-bolts.

E designates a foot-board, which when in place occupies a position adjacent the ground just in rear of and parallel with the hopper C. The foot-board E is supported upon brackets 6, each of which consists of a body portion arranged to underlie the footboard, and an overhanging lip e, which is adapted to abut against and overlie the edge of the foot-board. The brackets e are each secured to the frame of the machine by two sets of hangers e, the lower ends of which are secured in pockets 6 formed in the brackets e on opposite sides and adjacent the rear end thereof, and the upper ends of which are secured to the side pieces A A of the frame by the clampingbolts which clamp the rearmost lugs c of the hopper-casting c thereto and the clampingbolts which secure the bearings 12 of the axle to the side pieces.

F designates the furrow-openers, the bearings for which are pivotally supported in any suitable manner to the frame of the machine and which may be of any approved type. The furrow-openers are provided with the usual seed-tubes, which extend from the seedhopper O.

G designates a rock-shaft ournaled between the side pieces A A of the frame. The rock-shaft G has secured thereto a plurality of arms g, which engage rods f, secured to the bearings of the furrowopeners F so that they may be elevated, and also engage springs f, which surround said rods, so that the furrow-openers may be forced downwardly under a yielding pressure.

H designates a brace which is secured to one of the transverse connecting members B of the frame and extends rearwardly therefrom, said brace being apertured at its free end to afford a bearing for the central portion of the rock-shaft G.

I designates a casting which is secured to the rear side of the seed-hopper O and is provided with a downwardly-extending arm 'i, which is rigidly connected at its lower end in any suitable manner to the brace H, and with a plurality of arms i, the outer ends of which carry a segmental rack 11 The free ends of the arms t" are slightly offset, so that the segmental rack 17, carried thereby, will when the casting I is secured to the rear side of the hopper C be positioned a slight distance therefrom. The downwardly-extending arm i of the casting I is provided with a longitudinally-disposed groove 01 therein for a purpose to be hereinafter set forth.

K designates a lever which is pivotally secured to the central portion of the casting I and which is provided at the lower end thereof with a gear-like portion is. The lever K is also provided with a pawl k, which is adapted to cooperate with the segmental rack 11 to hold the lever in any desired position of ad justment, and with the usual hand-grip for elevating said pawl to disengage the same from the rack.

L designates a bar which is adapted to move longitudinally over the upper surface of the downwardly-extending arm i of the casting I, the upper end of said bar being arranged to underlie the segmental rack i and the lower end of said bar being provided with an inwardly-extending lip Z, arranged to underlie the downwardly-extending arm i. The bar L is provided on its under side with a longitudinally-disposed tongue Z, which is adapted to engage the groove t in the downwardly-extending arm & to prevent lateral movement of said bar thereon, and along one edge with a tooth portion of rack 1 which is adapted to mesh with the gear-like portion is of the lever K. The bar L is provided at its lower end with an offset foot 1 which has formed therein a horizontally-disposed slot Z.

M designates an arm which is rigidly secured in any suitable manner to the rockshaft G and is provided at its free end with a laterally-disposed stud m, which projects into the horizontal slot Z, formed in the foot Z of the bar L.

From the above-described construction it will be apparent that when the lever K is actuated the bar Lwill be raised or lowered, which, owing to its connection with the arm M, will rock the shaft G, and thereby effect the raising or lowering of the furrow-openers.

From the above-described construction it will be apparent 'that inasmuch as the lever for manipulating the furrow-openers is movable transversely of the machine and is positioned at one side of the footboard it is always accessible to the operator standing thereon and at the same time does not in any way interfere with his movements.

While I have described the segmental rack and the lever carried thereby as being secured to the seed-hopper, it is obvious that they might be supported in any suitable manner from the frame proper of the machine between the foot-board and said hopper. It will also be obvious that any desired form of furrow-openers may be used and any means may be employed for connecting the reciprocating rack-bar therewith to effect the raising and lowering thereof.
