nventi'on relates to. that-(dass` ot-seedn gmach Ines,inwhiclr` the quantity 'of seed'or. grain sown.A isfregulatedi by thellon gi-tudinal 'moving of thiefeedsupply shaft, and moreparticularly to thfatclfass i-ii'iwhich tlieearrying capacity of the feed-wheel is regulated by sliding.. through a scalloped ring at one sigde of the cup.A

lMy invention consists, first, in. acertain constructionoi' the scalloped sliding feed-wheel,

and sleeve in which it is carried,by which the wheel is enabled to receive grain freely, both at its periphery and sides; second,1iu the provision of cut-off4 wings to the sleeve in which thefeed-wheel is carried, to cut off thegrain at the top and-bottom of the cup, outside ofv the diameter of the sleeve, so that the operator `can increase or decrease the quantity of seed delivered without change in the width of seed-cup,`and at ltimes when the cup\is either full or empty; third, in a certainconstruction ofthe feed-wheel and its carrying-sleeve,

by which the wheel-is supported by a hub in the sleeve, and the .driving-shaft permitted to it loosely into the feed-wheel.' My invention further consists in certain peculiar devices and combinations of devices by which the leed-wheel is adjusted by the operator and the amount of seed-opening indicated.

In the accompanying drawings, Figure 1 is a view of the seed-cup, feed-wheel, and accompanying parts. Fig. 2 represents detached views ot' the scalloped ring, feed-wheel, and sleeve. Fig.` 3 is a section of the cup, scalloped ring, feed-wheel, sleeve, and driving-shaft. Fig. 4 is anunder-side view of' the seed-cup and-attachments applied to the bottom of the seed-hopper of a'machine.

A Aifrepresent the two parts of the seedcup, the partA having a recess at a a, to receive the scalloped ring B, and the part A inward projections b b. In this recess the scalloped ring B is permitted to revolve freely, but it cannot become displaced, owing to the presence of thcfprojections b b. The division of the case permits the introduction of the j sliding sleeve.

ring, and removal. when necessary# 0. ist-11e, reed-wheel, having upon its periphery Seedcavities or scallops, as shown, the scallops on the wheely corresponding, ,with the scallops in the ring, sothatfthe former mayv slide snugly within thelatter, and the latter prevent the escape ofI seed.. The feed-Wheel. has, a square aperture through it for. the in troduction ofthe driving-shaft D, the latter being preferably smaller than the holefin the wheel, so as to @HOW for irregularities in. mauufaetereand alf low. the shaft to` diverge from the axial linev of the feed-wl-,lel without causing the wheel to bindin its bearings.` In [jiracticerI-putantiin- .ber of these seed-cups and wheels under the same hopper, as is customary, the same shaft D driving the wheels of all the cups. E is'the It is bored to receive the hub c of the feed-wheel, so that a supporting-bearing is thus provided for the feed-Wheel at all points of its adjustment, andthe sleeve itself is sustained by the circular bearing-surface in the part A. The shaft D. is prevented from -movingindependently of the wheel by the presence of the pin d and the pin and washer el d, and it is by the lateral movement of the shaft that the amount of seed fed by theI wheel is regulated. In order that the wheel C may receive seed freely, I make the sleeve E of smaller 4diameter than the wheel, so as to expose the ends of the scallops at this end outside of the periphery oi' the sleeve, as'clearly shown in Fig. l; and in order to further facilitate the receiving of the seed upon theJ scallopsof the wheel, I lare the cup upward and outward, as shown in Figs. l and 3.

Inasmuch as the wheel U is laterally adjustable, and the sleeve for the purpose stated is of smaller diameter, I have to provide some means of preventing the seed from passing out, over, and under the sleeve when the wheel is adjusted to feed less than its full capacity. For this purpose I attach to the sleeve two wings, e e', which move through corresponding notches in the case A. (See Fig. 1 For the purpose of enabling this peculiar wheel and sleeve C .E to both receive and deliver seed with the greatestefciency, the daring `seed-cup A A has an oblique dslarge-orifice,

a', so that t-he seed forced out by the wheel will be discharged in a continuous stream. The Seed cup is secured tothe bottom of the hopper F, (see Fig. 4) byscrews f, the shaft D being operated, as usual, by suitable connection with the Wheels of the machine. To the shaft D I at- 'tach collars G G', which revolve with the secure the lever in any desired position, I ern-V ploy the slotted are J and thumb-screw J connected as shown in Fig. 4. I embrace the collar G by a stiff jaw-arm, K, towhich I rigidly secure a sliding pointer, L, having preferably several pointers, l, to Vpass over graduations M, as shown in Fig. 4, on the side of the hopper, the several pointers, with their separate indication-marks, being. designed for different kinds of seed.

I claim 1. The combination of scalloped feed-wheel C and sleeve E, the sleeve E being of smaller diameter than the Wheel C., to provide for the free access of grain to both the periphery and ends of the scallops, as set forth.

2. The combination of the peripheral seed- Whecl and the sliding sleeve E, provided with cut-oi' Wings e e at top and bottom ot' the seed-cup, gsubstantially as and for the purpose specified.

3. The combination of revolving peripheral operating substantially as and for the purpose specified.

6. The combination of sliding shaft D, col-fr lars G G", indicator K L ZM, sWiveling-jaw I, and lever 1I, connected and operating substantially as and for the purpose specilied.

In testimony of which invention I hereunto set my hand.
