SEEDER.

SPECIFICATION formingpart of Letters Patent No.- 274,460, dated March 27, 1883.

' Application filed August 14, 1882. (ModeL) To all whom it may concern:

Be it known that I, ROBERT S. CARR, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Seed ers, of which the following is a specification.

This invention relates to that class of seeders formed of a rotary seed-wheel inclosed in a seed-cup to which grain is admitted from a hopper, a series of the devices being generally arranged in one row upon a single actuatingshaft under a single hopper to form the wellknown grain-drill.

My invention consists of certain novelties of structure hereinafter specified.

Is In the accompanying drawings, Figure 1 is an elevation ofthe discharge side of the device; Fig. 2, a face view of the seed-wheel,

and Fig. 3 a vertical section of the device drawn transverse to the shaft.

A is the seed-cup, whose general form is as usual. B is one of the side walls of the cup;

0, the opposite sidewall; D, a disk fitted to revolve in the side wall 0 5 E, a bearing-boss upon the side wall B; F, the usual cup-shaft,

in this case shown as a round shaft; Gr, an

apron at the top of the cup, reaching from one side wall to the other; H, a segmental gate cast to wall B and reaching across the cup to the inner face of disk D; 1, the usual diso charge-weir; J a disk fastened to the shaft F; K, round pins fixed in disk J, and projecting through holes in disk D into the seedcup; L, the hub projecting outward from disk J; M, a pin-hole through huh L and shaft F to receive an attaching-pin; N, a mortise from inner face of disk J to pin-hole M, the hole M forming the bottom of the mortise; O, a gate fitted to slide through wall 13 into the cup and close the space between the bottom edge of 40 segmental gate H and the bottom of the seed cup; P, a stem to gate 0, extending through wall 0; Q, a notched head on stem P, grasping the periphery of disk J; R, a notch in the inner end of gate 0; S, a bearing in the hot- 5 tom of the cup, in which slides the stem 1?; 'l, the usual rivet for attaching the two parts B G of the cup together.

The shaft F is arranged to slide longitudinally through the cup, as usual, and the usual adjusting mechanism may be employed to effeet the motion. When the shaft is adjusted cndwise the pins K become projected more or less into the seed-cup. The gate 0 follows such movement of the shaft and feed-pins and closes so much of the space under the segmental gate H as is not required for the passage of the pins as they rovolve in the direction indicated by the arrow in Fig. 3. These pins carry the grain through the space between the end of the gate 0 and the side wall 0 toward the discharge I. The notch It in the inner end of the gate 0 permits the end of the gate to contact with the disk -D, and thus limit the further withdrawal of the pins K before the pins are so far withdrawn as to endanger their being withdrawn from the disk D entirely. The grain in the cup has free access to the entire surface of the pins, and the pins must be ofa round or other non-cutting section to prevent damage to the grain. The 0 apron G, extending, as it does, well back into the seed-cup, prevents theleakageoi' grain over the top of the segmental gate H.

The arrangement of stem 1? to engage the disk J and move the gate 0 yields an eliicient 7 and simple structure but, if desired, the gate 0 may be operated from the shaft by other means.

Then the disk J is cast the mortise N is formed without asepcrate core, and this mor- 8o tise naturally forms between its bottom and the side face of disk J the pin-hole M, thus saving the labor of drilling this hole through the hub L.

\Vhile I show a round shaft F, a square one may be used without involving any modifications of any part of the device not within the range of mechanical skill.

I do not claim, broadly, a feedwhccl formed ofpius projecting through a disk into the seede cup; nor do I claim, broadly, the combination of such form of seed-wheel with gates to close the front of the seed-cup.

I claim as my invention- 1. The combination, substantially as set 5 forth, of seed-cupA, having apron G, disk D, shaft F, feed-wheel J K, segmental gate H, and gate O.

2. The combination, substantially as set 4. The combination, substantially as set forth, of seed-cup A, having apron G and forth, of shaft F, feed-wheel J K, having hub 10 segmental gate H, disk D, shaft F, feed-wheel L, and mortise N M.

J K, and gate 0, having stem P and head Q.

5 3. The combination, substantially as set ROBERT CARR forth, 'of seed-cup A, having apron G and Witnesses: segmental gate H, disk D, shaft F, feed-wheel J. W. SEE,

J K, and gate 0, having notch It. JOHN LORENZ.
