DRILL.

v Reissue No. 2,640, dated June 4, 1867.

" a it may concern:

own that we, WORDEN P. PENN, iss, and JACOB BROSIUS, of Belleville,. ecounty of St. Clair and State of Illinois, have invented certain new and useful Improvements in Grain-Drills; and we do hereby declare that the following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

Figure 1 represents a vertical longitudinal section; Fig. 2, a similar view with the several parts thrown out of action; Fig. 3, a vertical longitudinal section of the hopper; Fig.

4, a top view of the hopper: Fig. 5, a bottom View of the hopper; Fig. 6, a perspective of conjunction therewith it consists in a peculiarly-formed reciprocating agitator for insur ing a free flow ofseed from the hopper, as will be hereinafter described; secondly, in connecting one of the regulating-slides at the bottom of the seed-box with an oscillating bar, and also connecting the teeth through which the seed are dropped with said bar, all in such a manner that by a single movement of a lever the flow of seed from the hopper can be entirely shutoff, and simultaneously therewith the teeth elevated free from the ground, or bya reverse movement of said lever these parts can be put into operative position again, as will be hereinafter described; thirdly, in the application of a pendent and, if desirable, adjustable support to the frame of the machine for the purpose of supporting a man behind the hopper to attend the machine, as will be hereinafter described; fourthly, in pivoting the teeth through which the seed are dropped to hinged arms, and again connectingsaid teeth to these arms by means of adjustable pivoted braces,

as will be hereinafter described.

In the accompanying drawings,'A represents the seed box or hopper for containing seed to be planted. This hopper is separated into three apartments by the two divisionboards a a, and mounted upon the carriageframe B, above which-this 'hopper is elevated by the standards, as represented in Figs. 1 and 2.

In the bottom of the hopper is a thin board or plate,d, which is securely fixed in its place,

' of which the openings through which the seed flow from the hopper can be shortened-4. a,

by adjusting the plate d longitudinally.

InFigs. 3 and 5 we have represented small blocks 0 c projecting from the plate d just under one edge of each opening, b, and forming checks to preventthe seed from getting under the plate (I. These blocks are secured to the upper plate, and serve a very important office in the machine, as above stated.

Beneath the longitudinally-adjustable slide d is a narrow plate, d extending along the bottom of the hopper as far as the perforations extend, and kept in contact with the slide d by means of straps c c, which allow this plate (1 to be moved backward and forward in a direction at right angles to the movement of the slide d, the object of which movement is to contract the seed-openings laterally or to entirely close them when the machine is not in opera tion.

On top of the plate (7, and guided by the division-boards a a, is a longitudinal central agitator, 0, having double-beveled edge-stirrers e c, projecting down from its "bottom edge and so arranged as to work over the intermediate spaces between the perforations through d, and keep the seed in the hopper over these perforations and ready to flow through them. Be-

sides these projections 6 there is a pin, 6 projectin g from the bar of the agitatorO over each hole I), for the purpose of keeping these holes always open, or, in other words, to prevent the BEST AVAlLABLE COPY works. The laterally-sliding plate (1 has eyes f,'projecting from its lower side, for receiving the hooked ends of rodsf' f, which are pivoted at their opposite ends to a narrow rocking bar,B,which hasits pivot-bearin gs on the side beams of the carriage-frame B. This pivoted bar E has a curved arm or handle, E, secured to it in such a position that when the parts are all in one position for operation this handle will hang down, as represented in Fig. 1. Then when said handle is moved around and hooked to the back of the seed-box A, as shown in Fig. 2, the slide 61 will have closed the holesthrough the seed-box and shut off the flow of the seed. I

- From the rocking bar E depend chains g,

- which connect with eyes projecting from the back part of the tubulart eeth G, and, as these teeth are connected to hinged rods H, the movement of the handle E in the act of closing the seed-holes in the hopper will at the same time elevate the teeth above the ground, as represented in Fig. 2.

The teeth Garehollow,tapering, and shovelpoint-ed, and receive the seed from the hopper A through flexible tubes, or in any other suitable manner, and conduct the seed into the ground. These teeth are pivoted to the forked ends of rods H,which are themselves pivoted to the forward part of the carriage-frame, as shown in Figs. 1 and 2, and to the front side of each tooth ashort brace, h, is pivoted, the upper end of which is again pivoted to the rod H by means of a pin passing through an oblong slot in the brace. This connection of the teeth to their hinged bars will allow of their being adjusted at different inclinations, and also allow of these teeth accommodating themselves to the surface of the ground traveled over. We propose in practice to em ploy wooden pins at such points as may be found neces-. sary when these parts are liable to meet with obstructions.

In the rear of the teeth, or in the rear part of the machine at any suitable point, a board, J, is suspended by chainsj, attachedto the side beams of the -frame,as shown in Figs. 1

and 2. Said boards are rigidly connected to hinged beams K K, which are also connected to the side bars of the frame A. V 4

The object ofthe board J is to furnish a stand, or, if desirable, a seat for a man stationed behind the machine to attend to the ad- "justing of the parts thereof, and by taking up (shortening) or lengthening the chain j the height of the stand-board can be adjusted to suit the convenience of the attendant.

In our invention we do not confine ourselves to the use of the braces h,'only as shown to j the hinged arms H, pivoted to theteeth G, as shown, as the arms H can be pivoted to the teeth G in front and the braces h pivoted to the teeth G laterally-i. a, to their sides-or the brace h can be 'piv'oted also to the teeth G in front.

Having thus fully described our what we claim as new, and desire t Letters Patent, isi 1. Bracing the drill-tooth to its drag-bar by means of a separate brace in such a manner tion, re by as to allow it to fold forward without breaking the wood pin, substantially as set forth.

2. The arrangement consisting of slides U, fixed plates 07, withcheck-pieces c and movable plates d 01 in combination with the hopper, all constructed, arranged, and operating in the mannerand for the purposes specified.

3. The costruction of agitating-slide with double-beveled projections e e and cleaningpins 6 in combination with the divisions a a, vibrating. hangers D and seed distributihg devices shown, substantially as and for the purposes specified.

4. The long cut-off plate d, arranged with the plates at d and slide 0, and connected with the drill-teeth by means of the pivoted vibrating bar E and chains 9, and operated by a handle, E, all in the manner and for the purposes specified.

5. The pendent stand-board J, arranged, substantially as described, upon a seed-drill, for the purposes set forth.

As evidence that we claim the foregoing we hereunto set our hands inv the presence of witnesses.
