GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 429,320, dated June 3, 1890.

Application filed December 23, 1889. $erial No. 334,607. (No model.)

To all whom it may concern:

Be it known that I, FRANK R. PACKHAM,a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Grain-Drills, of which the following is a specification.

My invention relates to an improvement in grain-drills; and it especially relates to constructions particularly adapted for use in shoe-drills, though the constructions may be applied with equally good results to other forms of grain-drills.

The object of my invention is to provide novel means for supporting and operating the lifting and pressure mechanism for raising and lowering the shoes.

A further object of my invention is to provide a novel means for supporting a seat in a convenient position with reference to the lifting and pressure devices.

My invention consists in the various constructions and combinations of parts hereinafter described, and set forth in the claims.

In the accompanying drawings, Figure 1 is a transverse sectional view, shown in elevation, of a machine embodying my invention.

and some of the parts being removed to better illustrate the novel features of my invention. Fig. 3 is a detail view in perspective of the seat and its supporting mechanism. Fig. 4 is a detail view in perspective of a portion of the raising and lowering mechanism. Figs. 5 and 6 are detail views of some of the parts hereinafter referred to.

Like parts are indicated by similar letters of reference throughout the several views.

In the said drawings, A A represent the frame of a drill, which is supported at each end 011 suitable carrying-wheels B, from whichmotion is derived to operate the feeding mechanism in a well -known manner, these constructions being omitted in the drawings for perspicacity, as they form no part of the present invention.

0 is the hopper, which is supported, as

usual, at each end on the respective side rails a a of the main frame.

D D are the shoes, which are connected to the main frame underneath the same in the usual way by drag-bars E. Each of the shoes is preferably provided with a pressing and covering wheel D, journaled in a suitable hanger D pivoted to the shoe D, and provided with means for connecting the same as tosecure a direct lift or pressure thereon.

In order to accomplish this without disarranging the other parts of the machine orinterfering with the proper distribution of weight with reference to the pivotal center 7 of the frame, I place the pressure and lifting mechanism at the rear of the hopper in the following manner: The side pieces a of the frame are extended backwardly beyond the hopper and the extended ends connected together by a tubular connection F. This tubular connection is preferably secured at each end in supporting-boxes b b, attached to I the extended ends of the side pieces a at, al- 80 though any other form of attaching device: may be used. The tubular connection F is preferably made of common'black pipe or gas-pipe cut to a suitable length and inserted at each end in the supporting-boxes b b, and held firmly "therein by set-screws b b','0r in any other well-known and suitable manner, the pipe being thus held firmly in position, and so forms a connection between the extended ends which adds rigidity to the frame and preventsthe displacement of the extended ends of the side rails by spreading or otherwise. On the tubular connection F as thus constructed I support the lifting and pressure mechanism. 5 This lifting and pressure mechanism consists, essentially, of a pressure-bar H, extending transversely across the frame A A, above the presserwheels D, and parallel withthetubular connection F. Arranged along the press- I oo ure-bar II is a series of supporting-bearings 0, each provided with ahorizontal sleeve portion 0' and a vertical sleeve 0 formed integral and at right angles therewith. The horizontal sleeve portion 0' fits the pressure-bar II, on which it is adapted to turn. The other sleeve portion 0 is preferably constructed and prepared to fit over connecting-links (Z, which pass through said sleeve 0 and are pivotally connected at their lower ends (Z to the hangers D of the pressing-wheel D. The connecting-links (Z are each provided with springs (Z arranged on said links between an adjustable stop and the supporting-bearin gs, substantially in the manner described in my former patent, No. etlOASG, dated September 3, 1889, so that as the pressnre-bar II is elevated or depressed the tension of the spring (Z is varied so as to vary the pressure applied to the wheel D and the shoe D. An adj ustable stop d is also provided above the bearing-support c to provide for lifting the Wheel and shoe when the bearing-support comes in contact with said stop. To guard against lateral movement of the sleeve 0 on the connecting-link (Z, I form an increased bearing along the edge of the link (Z by providing an extension 0 at the top of the sleeve 0 I also preferably cast the said sleeve on a chill to prevent wear by its movement 011 the link (Z. By the use of the projection c an increased bearing is formed to guard against lateral movement of the sleeve without increasing the length of the link, the stop (Z being adapted to pass the extended portion 0 and bear against the top of the sleeve proper 0 The pressure-bar II consists, preferably, of a straight round bar, each end of which is squared and tapered, as shown at e, and provided with a projecting screw-threaded por tion 6', as shown more clearly in Fig. 4:. The squared and tapered portion 6 is adapted to fit in a similarly-constructed opening f in a rocking arm I, and is secured therein by nuts e turned firmly on the screw-threaded portion (2, thus drawing the arm I tightly onto the square tapered portion 0.

The arms I are each provided in their opposite ends with an opening f, bored out or otherwise prepared to fit on the tubular connection F, the bar II being preferably made of such length that the rocking arms I, when placed 011 the tubular connection F, stand alongside of and in close proximity to the supporting-boxes b of said pipe-connection.

J is the lifting-lever, which is journaled at any convenient point on the tubular connec tion F. It is provided with an extended portion J, having a bearing g, preferably formed open on the under side, as shown in Fig. 5, and adapted to embrace the pressure-bar H, a pin g, adapted to extend through the ends of the open bearing being provided to hold the bar H within said bearing.

K is a ratchet-stand, also fitted on the tubular connection F and placed in proximity to the lever J, and held in any desired position by a set-screw h or in any other desired manner, the lever J being preferably arranged between said ratchet-stand and a collar h and provided with a suitable spring-bolt 7L2, adapted to engage with the ratchet-stand K. The ratchet-stand K is preferably provided with an extended curved portion K, passing under the pressure-bar II and joined to the hopper C, as shown in Fig. 1. By this construction it will be seen that by moving the lifting-lever J in either direction the shoes may be raised or lowered or pressure applied to the same, as desired.

By the construction of the ratchet-stand and lifting-lever, as described, the said ratchetstand and lifting-lever may be placed in any desired position along the tubular connection F, and pivotally connected to the pressurebar 11 to operate the same.

By usingthe independent rocking arms I and providing a separate and independent connection between the lifting-lever J and the pressure-bar the pressure-bar is adapted.

to be moved on its pivotal bearings more uniformly than when applied to one of the rocking arms at one end only of the pressure-bar, in which case the torsion of the rod is largely depended upon for raising or lowering the opposite end of the pressure-bar,

On the tubular connection F, preferably in close proximity to the lifting-lever J, I place a hanger L. This hanger is formed,preferably, of a single piece of round iron or steel, formed, as shown in Fig. 6, with two eyes 7a and a connecting loop 7a. The eyes 71; fit snugly on the tubular connection F, allowing the loop to depend underneath the same: Extending through the loop 7t is a tubular seatsnpport M, formed, preferably, of apiece of black pipe or gas-pipe, which is reduced or flattened at its inner end to receive a bolt Z, by means of which it is secured to a fastening-clip Z, secured to a cross-bar a of the main frame. This fastening-clip Z is provided with a series of openings Z by means of which the position of the support M may be varied as de sired by changing the location of the boltZ in the respective openings. The seat M is adapted to be supported on the seat-support M by providing a saddle Z, to fit over the seat-support M, the seat M being preferably secured in proper position by a bolt Z, which passes through the seat-support M, a series of openings Z being provided in said seat-support to furnish means for adjusting the position of the seat forward or back on the said seat-support. I also preferably provide on the seat-support M a foot-rest N, which consists, preferably, of a U-shaped strap m, extending over a collar on, formed in the nature of a saddle adapted to be secured in different positions on the seat-support M by a set-screw 111*, or in any other well-known or equivalent manner. Attached to the U-shaped bar m are the footsupporting pieces m preferably made separate from the bar on and adapted ICC to be secured thereto in different positions by means of a series of openings m by means of which the foot-supporting pieces may be raised or lowered with reference to the seatsupport M. It will be seen that by this construction I provide a'seat and seat-support which may be readily adjusted to any desired position with reference to the liftinglever and mechanism, the constructions being such that the seat may be readily removed and replaced, as desired.

The parts of the lifting mechanism and the seat-support are all so arranged as to be readily adjustable to all sizes of machines or for operating under different conditions. The support F and the seat-support M being tubular, as described, a very rigid construction is secured with very little weight of material, the construction being at once simple and compact and adapted to be easily and readily removable and adjusted to position.

If desired, one or more rocking arms I may be journaled on the supporting-pipe F and attached to the pressure-bar H. In large machines, where a considerable number of shoes are employed, I preferably form the liftingbar H with two or more parts and provide a lifting-lever for each part. When formed in two parts, the lifting-levers for the respective parts may be placed at each side of the seatsupport and in convenient reach of the operator from the seat. Where a very small number of shoes are used the lifting-lever may be attached at one end directly to one of the rockingv arms I, in which case the ratchetstand K may be formed with one of the supporting-boxes band secured directly to the main frame, as shown in Fig. 5.

It will be seen that all of the above-described constructions are adapted for either large or small machines, the constructions being at the same time so simple that very little machine-work is required to complete the same.
