1'0 (r66 w/wm, it may concern:

Be it known that I, SPENCER E. DAVIS, a

citizen of the United States, residing at Minit appertains to make and use the same.

My invention has for its object to provide an improved feeding device for drills or seeders; and to this end it consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a plan view of a feeding device designed in accordance with my invention, some parts being broken away. Fig. 2 is a vertical section taken on the line or x of Fig. 1. Fig. 3 is a detail in vertical section on the line 90 of Fig. 2; and Fig. 4 is a detail view showing the so-called feed-ring, looking at the inner face thereof.

The seed-containing receptacle is in the form of a cup 1, having an approximately scmicylindrical bottom and a separately-constructed side plate 2, and which side plate is rigidly secured to the body of the said cup by any suitable means-as, for instance, by a rivet or bolt 3. The body of the cup is open, so that it may receive the seeds or grain from a suitable supply device, such as the seedbox of a drill or seeder. In its front portion, just above its semicylindrical bottom, the cup is provided with a transversely-extended discharge-opening 4. The side plate 2 of the cup is formed with a large central opening 5, and surrounding this opening it is formed with a countersunk seat 6. Working closely within the seat 6 and with its inner face flush with the inner surface of the cup side 2 is a so-called feed-ring or rosette 7, that is formed with radial seed-pockets 8 in its inner face. The peripheral portion of the feedring 7 works down into a nearly semicircular groove 9, formed between the semicylindrical bottom of the cup and the detachable side 2, as best shown in Fig. 3. The seedpockets 8 of the feed-ring 7 extend radially with respect to the axis thereof, and at their ends and sides they join the inner face of said feed-ring on curved lines and without ab rupt shoulders. The importance of this construction will be considered later on. The outer extremities of the pockets 8 are so located that when they pass through the lower portion of the cup theywill extend completely to the supporting-surface of the semicylindrical bottom of the said cup. This is important, as it causes the pockets to pick up seeds from the very bottom of the cup and, furthermore, extends the agitation which they produce in passing through the body of the seeds completely to the bottom of the cup.

A corrugated hub or cylinder having grooves 10 ,frequently designated as a feedbucket, fits in a corresponding perforation 11 of the feed-ring 7 and is mounted to slide freely endwise through said ring while causing said ring to rotate therewith. The corrugated hub or bucket 10 is mounted to rotate and move endwise with the shaft 12, and which shaft receives rotary motion and endwise adjustments in the usual or in any suitable way.

Mounted on the shaft 1.2, adjacent to the hub 10, is a cutofl hub or follower 13, which is provided with a radially cut-off gate or rib 14. The hub 13 and its gate or rib 14 fit and slide through a correspondingly closely fitting seat in the integrally-formed side of the cup and are thereby held against rotation, but are free for axial adjustments. Said hub 13 is loose on the shaft 12, but is held for endwise movements therewith by a collar 15. The gate 14 inclines downward and forward, and its upper surface extends in a plane radiating approximately from the axis of the shaft 12 and intersecting the lower extremity of the discharge-opening 4 of the cup. The cup above the opening 4 is provided with a short transversely extended segmental web 16, which closely bears against the outer surface of the hubs 10 and 13 and prevents the seed or grain from running down and out through the opening 4 in the upper portion of the cup. The feed-ring, it will be understood, is rotated in the direction of the arrow marked thereon in Fig. 2. It is also evident that the p uantity of seed or grain that will be fed rom the cup will depend very largely upon the distance which the hub 13 and cut-oil gate 14 will move away from the feed-ring 7. In brief, by axial adjustments of the hubs 10 and 13 any desired quantity of seed or grain may be fed or discharged from the cup.

As already noted, the seed-pockets 8 are 0f such concave form, being free from shoulders and angles, that they will not out or inch the seeds or grain when the inner end of the cut-oif gate 14 is adjusted closely to or against the inner face of the feed-ring 7. It should be noted that the inner face of the feed-ring 7 is flat or approximately flat and smooth, except for the shallow pockets or depressions 8, and that the inner end of the cutoff gate or rib 14 is so constructed that it may be forced against the said smooth face when only very small seeds are to be fed. In view of this construction, even when the said cut-off gate is moved into close engagement with the smooth face of said feed-ring, the seeds will not be cracked or ground, as is the case where feed-rings are used which have ribs that project from their faces. In Fig. 3 the said outoff gate 14 is shown as adjusted nearly, but not quite, into contact with the smooth-faced portion of said disk. The concave form of the pockets 8 better adapt the pockets to dis charge the seeds, especially small seeds. The radial pockets discharge the grain held thereby very quickly after having passed the said gate. As said seed-pockets work to the very I bottom of the cup, they not only better stir up the grain, but as they feed the grain or seeds from the very bottom of the cup they do not tend to crowd the grain downward into the bottom of the cup. These shallow concave pockets are also better adapted to feed Texas cats or other bearded or fuzzy grains or seeds.

IVhat I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. The combination with a cup having a curved bottom extending to a dischargeopening, of a feed-ring working in one side of said cup and having in its inner face a plu rality of concave pockets that extend to'the face of said ring on curved lines and without angles or shoulders, a corrugated feed-hub mounted to slide through, but to rotate with said feed-ring, and a non-rotary hub having a cut-off gate or flange, cooperating with said feed-hub and feed-ring, substantially as described.

2. The combination with a cup having an approximately semicylindrical bottom extending to a discharge-opening, of a rotary feed-ring countersunk in one side thereof with its periphery working in a seat extending below the bottom of the cup, said feed-ring having in its inner face a plurality of radiallyextended concave pockets formed on curved lines that join the face of said feed-ring without angles or shoulders, and the outer extremity of which pockets pass to the bottom of said cup, under a rotary motion of said feed-ring, substantially as described.

3. The combination with a cup having a curved bottom extending to a dischargeopening, of a feed-ring working in one side of said cup, said feed-ring having an approximately flat inner face formed with shallow depressed pockets, but smooth except for said pockets, a corrugated hub having a cutoff gate or flange cooperating with said feedhub and feed-ring, the inner end of said gate or flange being adapted for close cooperation with the smooth inner-faced portion of said feed-ring, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

SPENCER E. DAVIS.
