IMPROVEMENT IN semen, DRILL, AND ROLLER.

dilge firlgthult retard in in this iititttt 35mm matting ymct it 1112 mm TO ALL WHOM IT MAY CONCERN: I

Be it known that I, LUTHER 'WAL'LACE, of Adrian, county of Lenawee, and State of Michigan, have invented a new and useful Improvementein a Combined Seeder, Drill, and Roller; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part oi this specification, in,which Figure 1 is a perspective view of a combined seeder, drill, and roller, embodying my invention.

Figure 2 is a vertical section, and shows the relative position of the seeder, drill, and roller.

Figure 3 is a perspective view of the concave seat for the seed-cylinder.

Figure this a side view of one of the drill-teeth, and of the mode of attaching it to a wooden'beam.

Figure 5 is a sectional view of the seed-cylinder, its journal, box, and driving pulley.

- A is the frame of the machine.

B B, the rollers.

C and C, respectively, a pulley and revolving standard, to hold up the forward end of the machine.

E is the seed-cylinder.

I is the chain or rope belt. 7

L is the upper, and L is the lower part of the broadcast-tubes.

K are the drill-teeth.

M is the beams of the drill-teeth.

N is the drill-tubes.-

S is the hopper.

V is the driving-pulley.

H is the chain-pulley.

W is the concave. w l

P is the-cross-bar to elevate the drill teeth out of the ground.

Y is the perpendicular slot in the upper ends of the drill teeth.

a is the shift-handle.

' his the shift-lever.

t is, the shift-pulley. p

h is the lever: to elevate the cross-bar P, which raises the drill-teeth.

i is the boss on the back of the drill-teeth, and connects with the cross-bar P.

fis a'feather in the='driving-pulley V, to prevent it fromturning on the shaft of the seed-cylinder E.

r m is a small elbow, to stay the lower end of the'broadcast-tubes L.

n is an iron rod running crosswise of the machine, through the eye of each beam of the drill-teeth, and through iron loops, bolted at suitable intervals on the under side of one of. the cross-pieces of the frame of the machine. I i

1 is a wooden safety-pin, to hold the wooden beamsM in their proper position with reference to the drillteeth K. v

' T is a hand-levenby whiclnthe chain-pulley H may be thrown into or out of gear with a grapple onthe shaft of the rollers.

: is an iron pin, which holds the tongue of the drill-teeth in the slot in the under side of the beams M.

q is a distributer. for scattering the seed when sowing broadcast.

D is a tongue or projection of the drill-teeth, which extends lengthwise in a slot made for the purpose'in the under side of the beam M.

' o is a seat for the operator.

The seed-cylinder Eis a round hollow tube, made of sheet or cast iron, or of any other suitable material,

and is perforated with holes bored in rows around the cylinder, the rowsto be spaced oiiequal to the spaces between the drill-teeth. The cylinder turns upon pivots, one of which carries the shift-pulley t, and the other .the driving-pulley V. Thecylinder is then placed, as shown in figJl, in the pit of the concave, W, which is also perforated with holes, 1 2 3 4.5 6, equal in number, size, and distance apart to those in the cylinder.

These holes formthe outlets into the drill-tubes N from the interiorof the cylinder E. The concave is also perforated with three other holes, 7 8 9, similar to those in the cylinders These holes form the outlets into 1 the broadcast-tubes and L: v t n I A chain or rope belt, I, runs irom the driving-pulleyV around the chain-pulley H, to impart a ,rotary motion ,to the seed-cylinder E, so that when the machine is-drawn along, and the hopper S filled with the seed to be sown, the latter works its way to the interior of the cylinder through the holes in it, and thence (according tothe position ot' theshift-handle a,) either through the outlets 1 2 3 4 5 6, and tubes N and drill-tceth'K, into the earth in drills, or through the openings 7 8 9, and broadcast-tubes L and L, upon .the distributor q, whence it falls in broadcast to the earth. I

The spaces between the holes being as great as the diameter of the holes, it follows that the seed can never enter both drill and'broadcest-tubesat the same time, butwill enter those in communication with the interior of the cylinder E, which, by means of the shift-handle a, is capable of being brought at pleasure in communication with either set of tubes Should you ever wish to grade the amount oi seed drilled in or sown broadcast, you have onlytopropor- Y tionately close the passages into the drill-tubes or broadcaststubes, which is done by-the shift-handle a, which moves the seed-cylinder E lengthwise along the pit of the concave, W,thus causing the passages to be partially closed, and in that proportion grading the amount of seed sown.

The driving-pulley'V is feathered on the shaft of the seed-cylinder, to prevent it from turning on the shaft, and the chain-pulley H may be moved laterally, by the hand-lover T, out of or into gear, with a grapple on the shaft of the rollers B B,'so as to remain without revolving or to turn with the shaft.

The drill-teeth K may be, when desired, elevated out of the ground by the lever k. They are held to their beams by the tongue 1), which fits into the slots made for th'at purposo in the under side of the beams. An iron pin, 1, and a wooden pin, 1, hold the tongue in the slot, the design of the safety-pin 1 being to prcvcntthc breaking of the drill-teeth by the giving way of this wooden pin when the point of the' teeth comes in contact with roots, or other obstructions. w I There is also a slot, Y, in the upper end of each drill-tooth, to allow this end to pass forward by' the tubes N, if the safety-pin should break, and thus avertall dan er of accident to thattube. Another object of the slot Y p is L0 enable theoperator, while sitting upon the seat 0, to discern whether or not all the tubes N are performing their functions. I design using the drill-teeth either wither withoutshovel-points.

One of therollers is rnade fast upon the shaft in order to carry the chain-pulley H, while the other'roller turnsfreely upon the shaft, so as to render it more easy to turn the machine around.

As it is not always desirable to roll the ground after sowing it, I have designed the using of' temporary wheels in place of the rollers B B, when not wanted, the wheel-shaft to be supplied with a chain-pulley, to.

drive the seed-cylinder, the same as the shaft of the rollers.

The rollers are made to be readily detached from the frame of ,themachine, and the wheels. substituted in their stead, and vice verse. I design, also, using any number of drill-teeth and broadcast tubes which maybe found desirable. I

I do not claim the invention of anything new in the simple combination of the drill and broadcast-isowor; but What I do claim as new is- 1. The employment of one hopper and one cylinder, or theirzequivalent, to supply both drill and broadcastsower with the seed 'to be sown, the whole arranged in front of the rollers B B, substantially as set forth and described; I 1

2. The hollow adjustable seed-cylinder E, in combination with the concave, W, broadcast-tubes L, and drill tubes N,-substantially as set forth and described. i
