SLPBCIPICATIQN forming part cf Letters atent No. 325,583, dated September l, 18785.
To all whom t may concern:
Be it known that I, JOHN L. Asnnnsfr, a citizen of the United States, residing` at Havana, in the county of Mason and State of Illinois, have invented certain new and useful Improvementsin Grain-Drills; and I do hereby Figure l represents a sectional side elevation of a grain-drill embodying my improvements. Figs. 2 and 3 are similar views of modified forms. Fig. 4 is a detail perspective view of one ofthe means used to operate the front frame. Figs. 5 and 6 are detail views.
This invention relates to improvements in grain-drills; and it consists in the novel features of construction, arrangement, and combination of parts, as more fully hereinafter set forth and claimed.
The drill-frame consists of two parts, A B, hinged together at (t, the former being sup` ported by brackets attached to the axle C, provided with the press-wheels c,whieh latter run in the rear of the runners D, connected with the frame B, the latter being provided with the hopper E and grain -spout e, oi' known construction. The seed is discharged from the hoppers by any suitable connections between the axle C and shaft F. rlhese parts are of well-known construction and arrangement, and need no further description.
The runners D are pivoted at their forward ends between ears Q,depending from the under side of a plate-bar, G, and are provided at their rear ends with a grain-boot, H, which has integrally cast therewith on its forward side, preferably near or at the top,a flange, h, to which the rear end of the bar G is secured by bolts or rivets. The forward end of the rod or bar G is pivoted between castings b, attached to the under side of the front crossrod of the frame B. Cast integral with the shoe on its rear side, and near the lower end thereof, is a lug, il, and on the rearv side of the hopper, near-rits top, is secured the lug or bracket j.
lis a rod passed through said lugs, and provided at its top above the bracket j with a nut, 7c, while at its lower end it is furnished with two adj usting-nuts, one above and the other below the lng t', as shown.
.I (see Fig. l) is a coiled spring encircling said rod, and held thereon between the lug t' and bracket j on the hopper, and the upper adjusting-nut resting on the lug@ of the shoe. The object of this spring is to force the run ner into the ground, and still, assisted by its yielding connection with the frame, as shown, allow it to yield upward when meeting with an obstructionas arock, for instance-the rods, and consequently the runner, being limited in its downward movement by a nut, k, on the rod above the lug or bracket j.
Instead of using the spring just described, I may dispense with it and use the rodfor the purpose of gaging the runner in its downward movement. In this construction I use a cross-piece under the bars that holds the runner true, and secure each end tothe side bar of the front frame, and apply weights of equal amount on each runner to force them into the ground the required depth. Of course the amount of weight to be used will depend upon the condition of the ground; or I may dispense with the rods altogether and suspend from the hopper or side bar of the front frame a curved hook, K, which embraces the bar G, as shown in Fig. 2, thus limiting the downward movement ot' the runner.
L is a gage fixed on the rear side of the hopper, and M is a wedge inserted between said gage and the front cross-bar of the frame A, as shown in the same figure.
The seat-frame N is connected at the forward end with the rear cross-beam of the frame B by a pivotal connection, not showin) and the rear end is supported on the rear erosspiece of the rear frame, A, by means ofthe pivotal rod O. The seat Z slides in the slot m in the top bar of the seat-frame for the lpurpose of assisting the driver in forcing the runners into the ground or raising them out of the same.
To the rear cross-beam of the front frame is securely fastened twobars,P P, extending backward and forming extensions of said frame. These bars extend nearly to the axle C, and are provided at their rear ends with holes n.
Q are treadles or foot-levers, connected at their forward ends with the bars l? P by links R, both the links and treadles being provided with holes, as shown. I have shown two forms of connecting these treadles. In Fig. 1 I show them as attached to the rea-r cross-beam of the frame A, while in Figs. 3 and 4 I show them as provided with hinge-blocks S, sleeved on the axle of the press-wheel; but I consider either one of these forms as the equivalent of the other. By applying weight on the front end of the treadles they act as a double lever 1 to force the runner into the ground, and by applying weight on the rear end they act in a reverse manner and throw the runner out of the ground, as will be readily understood. These movements are easily governed by the driver, who, by sliding his seat forward or back and placing his feet on either the front or rear end of the treadles, can lower or raise the runners, as occasion may require.
To assist the weight of the driver in raising the front part of the drill, I provide a handlever, T, which is substantially L-shaped, with the horizontal part U sleeved on the axle C, and its free end bearing under the extension of the front frame, as shown in Fig. 2. s is a rod bracing and strengthening said lever.
From the foregoing description the operation will be readily understood. The runner opens the ground, the seed is fed from the hopper through spout e and boot H into the furrow made by the runner, and is covered by the press-wheel c, which. follows directly in the path of the runner, the pivotal connections between the shoe and runner and the frame allowing the ruimer toadjust itself to the'unevenness of the ground.
The drill-frame being formed of two sections hinged together, and the hopper connected thereto, renders it yieldingly supported by the frame-that is to say, the frame being composed of hinged sections enables it to yield, and also the hopper which is carried with it, although rigidly connected to the frame.
It is evident that the treadle or foot-lever and the L-shaped hand-lever are equivalents of each other, both serving the same purpose, and consequently either one may be used, as circumstances may require.
Having thus described my invention, what I claim as new, and desire to secu re by Letters Patent, is-
1. In a grain drill, the combination, with the frame thereof formed in two parts hinged together, of a plate-bar, boot, and runner, the latter being pivoted at its upper end to said bar, which in turn is pivoted or hinged to the front end of the frame and connected to the boot, substantially as and for the purpose set forth.
2. In a grain-drill, a hopper yieldingly supported by the frame thereof, a runner pivotally connected at its upper end to said frame, a boot connected to the runner, in combination with the means described for raising and lowering the runner, substantially as and for the purpose specified.
3. In a grain drill, the combination of a frame formed of two hinged sections, having at its front end downwardly-depending lugs, a plate-bar pivoted at its forward end between said lugs, a boot connected-to one end of the bar and provided with a runner, the latter being pivoted between ears or lugs depending from the bar, substantially as and for the purpose described.
4. A grain-drill having its frame formed in two hinged sections, a hopper supported thereby, a boot, and a runner pivotally connected at its upper end to a plate-bar, the latter being connected at one end to the boot and at its opposite end pivoted to the forward. end of the frame, a rod connecting said boot and hopper, a spring coiled around the rod, and means for regulating its tension, substantially. as and for the purpose set forth.
5. In a grain drill, the combination of a frame formed in two hinged sections, a runner and boot connected together, a plate-bar pivoted to the forward end of the frame and also pivoted to the runner and connected at its rear end to the boot, and an operating-lever controlled by the driver for raising and lowering the front portion thereof, substantially as and for the purpose specified.
6. In a grain-drill, the frame thereof formed in two hinged sections, in combination with a treadle or foot lever hinged on the axle of the press wheels, the forward ends having perforations therein, an adjustable link connecting the treadle with the perforated end of bars forming extensions to the forward section of the frame, substantially as and for the purpose set forth.
7. In a grain-drill, a frame formed in two hinged sections, one of said sections carrying the hopper, the grain-boot and runners connected thereto and together by a pivoted platebar, and a rearwardly extending perforated bar, the other hinged section having a treadle or foot-lever, perforated at its forward end, connected to the perforated bar by an adjustable link, and a sliding seat to operate in connection with the treadle or foot-lever, substantially as and for the purpose specified.
8. In a graindrill, the combination, with the frame and hopper supported thereby, and the boot and runner pivotally connected thereto, of a lug on said hopper and a'lug integral with said shoe, a rod passed through said lugs, and adjusting-nuts, one on either side of the lug on the shoe, as and for the purpose specied.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
