IMPROVEMENT IN SEED-DRILLS.

To ALL ro WHOM I T MAY coNcnnN:

Be it known that I, HERMON V. DAVIS, of Amherst, in the county of Hillsborough, and State of New Hampshire, have invented a new and useful improvement on a machine for ,sowing garden and other seeds, called' a Seed-Drill; 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 of this specication, inrwhichi Figure 1 is a perspective and side view, and

` Figure 2 is a top view. v

I construct my machine as follows: I make a piece of wood, a, fourteen inchesl long, two inches wide, and one-half inch thick. On the lower end is a 'seed-box, b, three inches long, one and a half inch high, and two inches wide, with slide or other cover. I make of thin boards Aa hollow box or conductor, c, twenty-one inches long, two inches square. `The aperture is one and a halt` inch wide, and one inch high, three inches of the upper end of which is filled up. Two and a half inches from the lower end is a partition, d, a little above which is a mortise or hole, e, through the bottom of the conductor c, wherevthe seeds fall into the drill. .Inst above this, and fastened by screws to the bottom of the conductor c, and extending to the rear, is a small plough, f, made of'cast iron or some other metallic substance, grooved at the rear end, and two and three-fourths `inches in length, two inches deep; bevel-constructed vso as to pass through the soil freely; and to the rear end of the conductor c is attached a coverer made of cast iron, the upper end attached to the lower end of the conductor c by a pin, It, which passes through the sides of the rconductor-r, and through the covererg, upon which it hangs.' The lower part of thc coverer gis four inches by two and three-eighths of an inch thick, on the bottom of which are two wings, zz', ruiming diagonally, as indicated by drawings. To the upper end of the conductor c is attached the piece of wooda; at the lower end of this is attached the seed-box b. This piece a is attached to the conductor c by a screw, j, passing through it into the conductor c about one inch below theA upper end of the conductor c, and acts as a pivot, upon which it vibratesby the motion of the hand. This piece. or handle a extends eight inches above the upper c nd of the conductor fc, and made of suitable form to be grasped by the hand. Two inches below the pivotj is a cross-piece, 7c, fastened on 'each side by screws Z to studs of iron projecting from each sideof conductor c. yThe object of this device is to hold the seed-box b ina proper position upon disk n to vibrate freely. The screws L at each side act Aas. a gauge to thehandle or, which it strikes in its vibrations whenin operation. In the lower cud of handle a, at the bottom of the seedboX 6, isa hole, 0three-`ourths of an inch in diameter. Directly under the hole o in the seedfbox l1 is-a thin piece of sheet iron, with a round hole, through which theV seed passes, to protect. the 'wearing of the parts. Just below the seed-boi r b, and on the top of the conductor c, is a disk or circular piece of sheet iron,fn,in the centre of which is a hole iuiwhich is inserted a screw or pin, uponwhich it acts as on a pivot. Toward the outer edge are four or more holes of various sizes, adapted to the passage of the dierent-sized seeds which passA through them, and in such position that when the disk n is turned, the holes in the disk n', marked severally p pp, come directly under the hole o in the seed-box b, and directly over the hole in the conductor under the bottom of the seed-box. l y

To operate the machine the operator takes hold oi' the handle a and draws the machine toward him, and at the same time moves the handle aV from right to left, and vice versa. The seed-box b being attached, the seed pase down through the hole o and p, falling into the aperture of` the conductor e, then passing out at the hole e, at the lower end of conductor c, into the groove in the plough f, then falling into the drill made bythe plough f, then being covered by the coverer g, which follows.

What I claim as my invention, and desire to secure by-Letters Patent, is

The several parts, marked a yZ c j' g n 7c, when the several parts Iare constructed, arranged, and operated as Specified.V
