DRILL.

SPECIFICATION forming part of Letters Patent No. 311,397, dated January 2'7, 1885.

Application filed September 6, 1884. (N0 model.)

To all whom it may concern.-

Be it known that I, JOHN M. WESTOOTT, a resident of Richmond, inthe county of Wayne and State of Indiana, have invented certain new and useful Improvements in Grain-Drills, of which the following is a specification.

My invention consists in improvements in grain-drills, and more particularly to that class denominated shoe or runner drills.

The first object of my invention is to provide automatic vertically-adjusting shoes or runners, which are pivoted to evener-bars so that one shoe or more of the series will rise as the shoe at the opposite end is depressed,

whereby the shoes are enabled to conform to the irregularities of the ground and secure a more uniform planting of the seed.

Another object of my invention is to provide automatic shipping devices for throwing the seeding devices out of gear as the shoes are raised, and bring them into gear when the shoes are lowered.

Another object of my invention is to provide means for locking the shoes in or out of the ground, as the case may be.

Another object of my invention is to suspend the principal part of the weight of the drill upon a series of covering-wheels mounted upon a supplemental frame attached to the main frame of the drill and supporting the drivers seat thereon.

Another object of my invention is to provide an improved hinge for the lid of the graiirbox, so that it will, when raised, be in a plane practically parallel with the .back of the boX, all of which will be fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure l is a perspective view of my improvement attached to a grain'drill. Fig. 2 is a central longitudinal section Fig. 3, a rear elevation of the method of hinging the shoes to the evener-bar; Fig. 4, an elevation of the unshipping mechanism; Fig. 5, an end view of a part of the same; Fig.6, a detail View of the lifting-latch; Figs. 7. 8, 9, detail views of my improved hinge; Fig. 10, a plan View of the lifting rack-bar; Fig. 11.an1odifieation of the method of hinging the shoes. Fig. 12,

a top plan view of the preferred form of hinging the shoes.

A represents the tongue of the machine,

which is fastened to the cross-rails A A. The rear end of the tongue A is connected to the lever device swiveled upon the ridingframe.

B B represent the side rails of the main and riding frame; I), an axle supporting a series of ground and covering wheels, 0. The axis is journaled to the frame B by means of hangers.

B represents side rails of the main frame.

1/ represents cross-rails secured to the rails B, the forward ends resting upon rail 12 of the supplemental frame A, upon which the grain or seed box a is mounted.

, 0 represents an iron bracket, which is bolted to the rails of the frame A, and to which brackets the rails B are pivoted at either end of the seed-box, as shown in Fig. 1.

0 represents the drivers seat,which is sup- 7o ported upon the rails of the main frame B, which may be made adjustable thereon, so as to be moved forward or backward to regulate the weight of the driver upon the main frame and to balance the load upon the forward end of the tongue, which is supported by the neck-' yoke.

D represents the lock-lever. It is provided with a bell-crank arm, D, which is pivoted to the tongue A by means of links d.

d represents a brace connecting the lever D to the bell-crank arm D.

E represents a rack-bar, which is slotted so as to receive the lever D, which projects up through the same. 8 5 6 represents a catch, whichis adapted to engage iu notches '1 and 2, formed in the rackbarE. As the lever D is pulled backward toward the operator it elevates or lifts the tongue A, and with it the rear end of the shoes'F. The catch 6 engages with oneof the notches '1 and holds the shoes out of the ground, or prevents their going too deep into the ground. \Vhen the lever D is moved forward, the shoes F are depressed, and the catch e engages with one of the series of notches 2 and locks the same in the ground. As the lever D is moved backward, the forward end of the main frame B is depressed and the shoes F are raised. This is a mere incident to the I00 form of construction and hinging of the two frames together, and of the hinging of the shoes F to the drill-frame A.

f represents the shoes or runners pivoted to the forward end of the frame A. The shanks f are secured to the rear end of'the frame by evener-bars, which I will now proceed to describe.

b represents the rear rail of the seedingframe A. 9 represents hangers or brackets rigidly secured to the rail 1).

H represents an evener-bar pivoted to one of the brackets g by an axial bolt, 2'.

I represents secondary evener -bars pivotally attached to the evener-bar H, as shown in Fig. 12.

This mode of pivoting the shoes to the main frame allows two of the series to rise as the other two are depressed; or it allows one of the series of two to rise, and the other one to fall as the supplemental bars I turn on their pivots h. A modification of this mode of hinging would be to pivot the shank of the shoes f and the evener-bar I to a stationary supplemental bar, H, as shown in Fig. 11, instead of having the bar H pivotally attached to therail b.

The construction shown in Fig. 11 would accomplish a part of one of the objects of my invention, but not in so approved a manner as the form shown in Fig. 12.

The mode here shown of pivoting the shoes or runners to evener-bars so that one or two may rise as the opposite one or two of the series are depressed, accomplishes very important and useful results in the planting of seed, first, as it allows the shoes to automatically rise over small obstructions without throwing the entire series out of the ground; second, it allows the shoes or seed-dropping spouts to rise and fall and accommodate themselves to lateral inequalities of the ground; and the method of pivoting the entire series and operating it by a lock-lever, D, allows the entire series to be raised, lowered, or depressed to accommodate the runners to the inequalities of the ground which run transversely to the path of travel.

I11 order to automatically throw the seed devices in or out of gear as the shoes are raised and lowered by the lever D, I have provided the following instrumentalities:

. The seeding devices are operated by transmitting the power of the team from the main axle b to the shaft J, attached to the seed-box a and connecting the seed mechanism.

K represents a sprocket or spur wheel, the hub of which journals upon the sleeve h, secured to the shaft J, so as to run loosely thereon.

L represents a clutch on the shaft J, and Z clutch-teeth formed upon clutch L and the hub of the wheel K.

Z represents a bracket projecting down from the seed-box, the lower end of which is forked, and rests in an annular groove, a, formed on the hub of the wheel K, and this holds the wheel from moving laterally upon the sleeve 70, and yet allows it to run loosely thereon.

N represents an arm having a semicircular journal, at, which works in the groove n of the clutch L.

N represents a reciprocating shaft, forming the reciprocating bar N. These parts are so arranged that when the lever O is raised bar N will be reciprocated, coiling the spring m and moving the clutch L out of engagement with the wheel K, which will then run loose on the sleeveK and convey no motion to the shaft J. \Vhen the arm 0 of the bell-crank lever is released or lowered, the spring at will recoil and bring the clutch L into engagement and set the shaft J in motion. In order that this action may be accomplishedautomatically as the series of shoes or runners F are raised and lowered, I provide the liftinglug P, pivotally attached to one of the crossrails b.

12 represents a lug, which engages with the under side of the tongue A, so as to prevent the forward end of lug P from dropping. As

the tongue A is raised, the forward end of rail 1) is depressed and the latch P lifts the lever O, throwing the clutch L out of engagement with the wheel K and stopping the motion of the feed-shaft. As the drill-shoes F are lowered, the spring m brings it automatically into engagement and sets the feed in motion.

I do not desire to limit myself to the details of constructing the automatic unshipping mechanism, as various forms of clutches and means of communicating the motion from the tongue A. to the rocking-frame B may be employed in lieu of that here shown.

It has been customary in the use of graindrills to stitch canvas upon the inside of the back of the grain-box and to the lid, so as to prevent the grain, when it is poured into the box, from passing out a crack or opening between the lid and grainbox. This form of covering the crack in the grain-box, to prevent the grain from scattering out when the seed-boxis filled, is objectionable. It is trappy and liable to be pulled off.

I have invented an improved form of hinge for connecting the lid Q to the grain-box a, so that the lid Q forms a close joint on a plane with the vertical edge q of the box. In order to accomplish this it is necessary for the lid Q to move forward as it is raised, and to move backward when it is lowered to bring it into position. This I accomplish in the following manner:

R represents a straight horizontal slot formed upon the inner edge of the end partition, r.

S represents'a the end 1'.

pin projecting inward from I the lid is raised and form a butt-joint.

8 represents an ear depending downward from the lid Q, as shown in Fig. 8.

T represents a segmental slot, pierced in the ear '8, into which slot the pin S projects, so as to assist in guiding the movement of the lid Q.

t represents a pin projecting from ears into the straight slot R.

The pins S t and slots R T form the hinge, and act as follows: As the lid Q is raised, pin tmoves forward in the slot It and the pin S moves circularly in the slot T, causing the upward and forward movement of the lid Q. These parts are preferably so constructed that the rear edge of the box a and the lid Q will lie in the same vertical plane when Of course, a lap-j oint might be employed; but it is not so durable. When the lid Q is depressed, the pin tmoves backward in the slot R with the circular movement of the pin S in the slot T, and the rear edge of-the lid Q will be carried backward, so that its under surface will rest upon the vertical edges of the grain-box, completely cover it, and shed the moisture.

The unshipping mechanism shown in the application operates differently from the unshipping devices used upon ordinary graindrills in that the yielding hinged frame operates in the act of rising and bending upward to move a pivoted latch operating a lever for moving the clutch devices,and my claims herein are limited to this specific class of graindrills.

I claim 1. In a grain-drill composed, substantially, of a main frame, B, supported on the series of covering-wheels G, and hinged to the supplemental frame A, and-the tongue B, rigidly secured to the supplemental frame, in combination with the runner F, hinged at their front ends to the supplemental frame and at their rear ends to an evener-bar, H, which is in turn secured to the supplemental frame, substantially as specified.

2. In a grain'drill composed,substantially, of a main frame, B, supported upon a series of ground-covering wheels and hinged to a supplemental frame rigidly connected to the tongue, in combination with the said runners F, hinged to the supplemental frame at their front ends and to an evener-bar, H, at their rear ends, and a locking-lever, D, journaled upon the axle of the main frame for operating the runner-frame, substantially as specified.

3. In combination with the main frame B, the bell-crank lever D, journaled on the main axle, said leverbeing loosely hinged to the main frame, and provided with locking devices for locking the frames together and allowing the runners F to vibrate vertically with the pivoted evener-bar H, substantially as described.
