NITED STATES ATENT GAYLARD WV. DENYES AND OW'EN SOl-IUTT, OF CASSOPOLIS, MICHIGAN.

GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent N 0. 672,596, dated April 23, 1901. i Application filed January 19, 190].- Serial No. 43,897. (No model.)

To all whom it may concern:

Be it known that we, GAYLARD W. DENYES and OWEN SOHUTT, citizens ofthe United States, residing at Gassopolis, in the county of Cass and State of Michigan, 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.

Onrinvention relates to improvements in grain-drills, and more particularly to that class of drills in which a shoe is yieldingly pressed into the soil by means of a spring; and its objects are to provide improved means for adjusting the tension on the spring, to provide improved means for securing the spring in place, to provide a simple and durable device, and to provide the device with certain new and useful features hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a plan view of a device embodying our invention. Fig.2 is a side elevation of the same with parts broken away; Fig. 3, a detail of the adjusting-cam; Fig. 4, a detail of the cam-holding plate; Fig. 5, a detail of the fulcrum-block; Fig. 6, adetail section of the T-head before attachment to the spring, and Fig. 7 the same after attachment to the spring.

Like letters refer to like parts in all the figures.

A represents a portion of the frame of the drill; B, one of the drill-shoes; G, the drawbars for the shoe, extending forward and upward in a curve from the front of the shoe and pivoted at the forward end to the frame.

D is a tube extending vertically from the rear of the shoe to conduct the grain to the shoe.

D represents lugs extending laterally from the upper part of the tube D, which lugs are engaged by the parallel bars E to lift the shoe clear of the soil when the machine is out of action. The bars E extend horizontally at each side of the tube D, and thence vertically at the rear of the tube and are pivoted to the vertically-movable end of the rocker-arm F, attached to a rook-shaft G, which shaft is adjusted by means of a lever H, having a latch to engage a notched sector I, fixed on the frame.

Pivoted in the forward endsof the bars E is a T-head P, having a transverse opening, in which is inserted the end of the spring J. To secure this spring in the T-head, lugs P P are provided at each side of the opening in the head, and these lugs are bent inward and engaged with recesses in the opposite sides of the spring, as illustrated in Figs. 6 and 7. The spring J extends forward to between the draw-bars 0, near the forward part of the same, and is there bent downward and rearward in a curve and engages a fulcrum-block K, secured between the draw-bars by atbolt L and having flanges N engaging the drawhars to aid in holding the block in place. The fulcrum-block K is also provided with a loop K, engaging and holding the spring-arm J from moving forward. The spring-arm Jextends rearward between the draw-bars G and engages the upper side of a grooved eccentric M, rotatively adjustable between plates 0 O,

engaging the respective draw-bars.

One of the plates 0 is provided with a corrugated boss 0, which engages and meshes with like corrugations in the end M of the hub of the eccentric. The other end M of this hub is made hexagon or square to receive a wrench by which the eccentric may be turned to adjust the same and put tension on the spring-arm J. A bolt L passes through the draw-bars, plates, and eccentric and secures the whole firmly in place.

From the foregoing description the operation of our device will be readily understood without further description.

What we claim, and desire to secure by Letters Patent, is-

l. The combination of a shoe, draw-bars attached to the shoe and pivoted to the frame, a fulcru m-block and an adjustable eccentric attached to the draw bars, a spring engaging the fulcrum-block and eccentric, and means for adjusting the tension of the spring, substantially as described.

2. The combination of a shoe, draw-bars attached to the shoe and pivoted to the frame, a fulcrum-block between the draw-bars, an eccentric between the bars and rotatively adj ustable, a spring engaging the eccentric near one end and having a bent portion engaging the fulcrum-block, and a vertically-adjustable arm connected to the other end of the spring, substantially as described.

bars, an eccentric between the bars having a hub provided with corrugations in the end and a squared portion, a plate attached to one of the draw-bars and having a corrugated boss engaging the corrugated end of the hub, a bolt passing through the draw-bars, plate, and hub, a spring engaging the fulcrum-block andeccentric at the forward end, and means for vertically adjusting the rear end of the spring, substantially as described.

5. The combination of a shoe, draw-bars attached to the shoe at the rear and pivoted at the front, a fulcrum-block having flanges to engage the draw-bars and a loop to engage the spring, a bolt extending through the drawbars and block, an eccentric having a hub provided with a squared portion and end corrugations, plates engaging the ends of the hubs and provided with corrugations engaging the corrugations in the hub, a bolt extending through the bars, the plates, and the hub, a spring engaging the fulcrum-block and the eccentric at one end, and means for vertically adjusting the other end of the spring, substantially as described.

6. The described means of securing a T- head-to a spring, consisting of an opening in the T- head to receive the spring, a recess in the spring and a lug on the head adapted to be bent and engage with the recess in the spring, substantially as described.

7. In a grain-drill, in combination with a spring attached to the draw-bars of a shoe and provided with opposing recesses, and parallel bars attached to a vertically-adjustable arm, a T-head pivoted in the bars and having'an opening to receive a spring, and lugs at each side of the opening to engage the recesses in the spring, substantially as described.

8. In a grain-drill, the combination of a shoe, a tube on the shoe, laterally-projecting lugs on the tube, draw-bars attached to the shoe atthe rear end and pivoted at the front end, a fulcrum-block and an adjustable eccentric between the draw-bar's, a vertically adjustable arm, parallel bars pivoted to the arm and embracing the tube, a spring engaging the fulcrum-block and eccentric, and a T- head pivoted in the parallel bars and attached to the spring, substantially as described.

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