IMPROVEMENT IN SEED-DROPPERS.

Specification forming part of Letters Patent No. 135,743, dated February 11, 1873; reissue No. 5,529, dated August 5, 1873 g application filed J une 25, 1873.

To all whom it may concern:

. Be it known that I, FRANK W. YOUNG, of Holden, in the county of Johnson and State of Missouri, have invented certain new and useful Improvements in Seed-Droppers; and I do hereby declare that the following is a full, clear, and exact description thereof, references being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangement of an improved seed-dropper for corn-planters, which is simple in construction and reliable in operation, and so arranged that the size of the dropping apertures may be conveniently adjusted to any desired extent, according to the amount ofseed required to be dropped at a time, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a plan view of my seed-dropper, partly in section. Fig. 2 is a detail section of the same taken through line a' Fig. 1. Fig. 3 is a detail view of the lower or main part of the dropping device, and Fig. 4 is a detail view or" the under side of the upper disk and one ofthe adjustable arms.

A B are two boards which form the bottom of a seed hopper, and between which is placed a wheel, U, pivoted at its center to' the lower board B. In the upper board AisV formed a round hole of such a size that the edge of said board A may slightly overlap the upper edge of the wheel U, so that the seed may rest upon the board A and wheel U, but cannot get into the space between the boards A and B. Through the wheel O, near its outer edge, is formed a circle lof holes or slots, c1, the outer parts of which are semicircular. The upper ends of the holes c1 are open, so as to receive seed from the hopper, andth eir lower ends are closed by the board B, so that the seed cannot escape from the said holes until each hole c1 comes successively over a hole, b', in the board B, through which its escapes to the ground. The middle part of the upper side of the wheel G is recessed to receive the arms D, which are made in about the form shown in Figs. l and 4, and are pivoted to the under side of the disk E, so that they may be drawn inward or pushed outward by turning the disk E in one or the other direction. The inner end of each arm D is prpvided with a slot, w, as shown in Fig. 1, and a pin, Q from the disk E passes through said slot. The outer ends of the arms are concaved, and enter the inner ends of the holes c1, so that the said holes or dropping apertures may be enlarged or diminished by the inward or outward movement of the arms D. The disk E is placed upon the pivot of the wheel C, and, when adjusted, is clamped to said wheel C by a nut screwed upon the upper end of said pivot, thus holding the arms D rmly in the position to which they havey been adjusted by the turning of the disk. Upon the edge of the wheel C are formed as many ratchetteeth c2 as there are dropping-holes c1 in the wheel, as shown in Figs. l and 3. F is a sliding bar, to which a reciprocating movement is given in the ordinary manner and by the ordinary means. F enters a guide-groove in the space between the boards A B, and to it are pivoted two pawls, G H. The forward end of the pawl G has a hook formed upon it to take hold of the ratchet-teeth c2 of the wheel C, and turn said wheel as the bar F is moving outward. The forward end of the other pawl H is so formed as to take hold ofthe ratchetteeth of the wheel C as the bar F is moved inward. The movement of the bar F is so adjusted that the wheel C, at each movement of said bar F, will be turned a distance equal to the space between two adjacent holes, c1. The forward or engaging ends of the pawls GH are held against the wheelC bya U or other spring, I, placed' between the other or rear ends of said pawls, as shown in Fig. 1.

Having thus fullyfdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The slotted and pivoted arms D D, when used in connection with a rotating dropping wheel, substantially as and for the purpose set forth.

2. The combination of the slotted pivoted The end of the bar' 2 Y K l 5,529
