GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 466,523, dated'Ja-nuary 5, 1892.

Application filed March 11, 1891. Serial No. 384,689.

Be it known that we, PHILIP M. GUNDLACH and JOHN P. GUNDLAOH, citizens of the United States, residing at Belleville, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Grain-Drills; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which'it appertains to make and use the same.

The present invention has for its object to provide an improved grain-drill construction embodying the following novel and advantageous features: first, an improved arrangement and location of parts whereby the usual rectangular carrying-frame of the drill can be dispensed with and the seed-hopper attached directly to and supported by the axle,

While the tongue and the diagonal hounds or braces by which it is connected to the axle afford a ready and convenient means for the attachment of the cross piece or rail to which the drag-bars of the seeding-fiukes are attached at points intermediate of its transverse length, so as to equalize the strain and avoid springing or bending of the cross-rail in use and in a vertically-ad j ustable manner, so as to regulate the drag of the fluke-points upon the ground and enable the same to be adjusted to suit the degree of hardness of the ground met with, its lowest adjustment being for very hard ground; second, a pivotal attachment of the seed-hopper to the axle and connectingbraces extending forward from the hopper to the tongue-frame or hounds inorder to admit of a slight adjustment of the seed-hopper in a pivotal manner, so as to balance the drill and cause it to run easy, and which at the same time constitutes a very'rigid and substantial attachment of the seedhopper in place; third, a simple and effective knuckle attachment for the lower end of the hand-rod by which the cross-rail of the drag-bars is manipulated, so as to afford the proper leverage to said rod in pushing down or pulling up the cross-rail from its respective upand down positions with the corresponding straight and zigzag position of the seed-fiukes, the hand-rod being provided with a stop made adjustable to suit the verticaladjustment of (No model.)

the cross-rail hangers above mentioned,which stop is adapted to engage against'a catch at- We attain such objects by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of our improved drill complete; Fig. 2, a detail longitudinal section illustrating the cross-rail of the grain-fiukes in its up position; Fig. 8, a similar View illustrating the same in down or straight position; Fig. 4, a front elevation of the hand-rod for operating the cross-rail and its connected part-s; Fig. 5, a similar view of the catch for said rod or the body of the axle.

Similar letters of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the axle of the drill, having the usual groundwheels and connected to the tongue 2 by means of the diagonal braces on hounds 3 and an upper cross-rail 4, as clearly indicated in Fig. 1. In the present construction the rear end of the tongue 2 extends back only to the cross-.

rail 4, so as to leave a clear space back of said rail for the movement of the mechanism by which the fluke-rail is manipulated, as hereinafter described.

5 is the seed-hopper, the end pieces or castings of which are formed with pendent feet 6, that are pivotally connected by bolts with the bracket-pieces 7 on the axle.

8 are tie or connecting rodsextending from the seed-hopper to the tongue-frame and adjustably connected to the hopper in any suitable manner, so that the hopper may have a limited pivotal movement imparted to it, so as to balance the-drill and make it run easy.

9 is the cross-rail, to which the drag-bars 10 of the grain or drill fiukes are connected in the usual manner, this cross-rail 9 being journaled to its supporting-brackets, so as to be capable of the usual pivotal movement from an up to a down position to draw the drillfiukes into either a straight or zigzag line, in accordance with the nature of the ground.

. In the present invention the hangers ll'are connected to the'cross-rail 9 at points intermediate of its length and are of a forked for- ICO mation to fit the diagonal braces or hounds 3, to which they are bolted in a vertically-adj ustable manner, preferably by means of a cross-bolt passing through one of a series of holes or slots in both the hanger and the hound, as indicated in Fig. 2. Any other well-known adjustment mechanism may, however, be used instead without departing from the spirit of this part of our invention.

The novel means by which the cross rail or bar 9 is moved into its diiferent positions, as

above described, consists of a hand-rod 12,

extending backward between the axle and the seed-hopper to within easy reach of the operator, its forward end being pivotally connected to a bent lever 13,that is journaled to the back of the cross-rail 9 by a shoe 14, in which it has limited pivotal movement, as shown, its construction being such that when the said rail is in its down position said lever bears against the rail, as shown in Fig. 3, to aiford a fulcrum for the pull or hand rod 12 in drawing the cross-rail into its up position, and when the rail is in its up position the said lever will bear against its shoe 14 to afford a fulcrum for the hand-rod in forcing or pushing the cross-rail into its down position.

15 is a stop on the shank of the pull-rod 12,'

made adjustable by means of a wedge 16, so as to equalize or compensate for the change in position due to the vertical adjustment of the hangers 11 of the cross'rail.

17 is a catch-piece secured to the axle and provided with a projecting edge, against which the stop 15 engages to lock the parts in their up position, and a loop formation 18, through which the hand or pull rod 12 passes? catch-piece 17, attached to the axle, essenand is confined in proper position.

By our improved construction the drill-i frame can be of an exceedingly light construe-l tion and still afford ample strength and stiifness of parts, the different members of the present frame construction coactin g in a very perfect manner to stiffen and brace each other and at the same time furnish a more the cross-rail 4, so as to leave a clear space at the rear of the same for the movement of the fluke-setting mechanism, essenti. lly as herein set forth.

2. In a grain-drill, the combination of the axle 1, tongue 2, diagonal hounds 3, and crossrail 4 with the cross-rail 9 and the hangers 11 secured to the hounds 3 and having pivotal connection with the cross-rail at points intermediate of its length, essentially as set forth.

In a grain-drill, the combination of the drill-frame, the hangers 11, secured thereto in a straight vertically-adjustable manner, and across or fluke rail 9, pivotally connected to the hangers, so as to be capable of a pivotal up-and-down movement to draw the drillflukes into a straight or zigzag line or rank, substantially as described.

4. In a grain-drill, the combination of the axle 1, tongue 2, diagonal hounds 3, andcrossrail at with the cross-rail 9 and the hangers 11, secured in a vertically-ad j ustable manner to the hounds 3 and having pivotal connection with the cross-rail at points intermediate of its length, essentially as set forth.

5. In a grain-drill, the combination of the cross-rail 9, pivotally attached to the frame of the drill, with the hand or pull rod 12 and bent lever 13, attached to the back of said rail by a shoe 14, to be capable of a limited pivotal movement, essentially as set forth.

6. In a grain-drill, the combination of the cross-rail 9, pivotally attached to the frame of the drill, with the bent lever 13, attached to the back of said rail by a shoe 14, to becapable of limited pivotal movement, the hand or pull rod 12, adjustable stop 15 thereon, and

tially as set forth.

7. In a grain-drill, the combination of the cross-rail 9, pivotally attached to the frame of the drill, with the bent lever 13, attached to the back of said rail by a shoe 14, to be capable of limited pivotal movement, the hand or pull rod 12, the stop 15 thereon, and catchpiece 17, attached to the axle and provided with a loop formation 18 for confining the hand-rod 12 in place, essentially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
