FEED-"CUP FO'R FERTI L'rzE'R- DI'STRIBUTERS.

SPECIFICATION forming part of Letters Patent No. 236,900, dated January 25, 1881.

Applicationfiled December 9, 1879.

To all whom it may concern:

Be it known that I, WALTER MARKS, of Ohapinville, Ontario county, New York, have invented certain Improvements in Feed-Cups for Fertilizer-Distributers, of which the following is a specification,reference being had to the at iexed drawings,-in which- Figure 1 is a plan view of my improved feed-cup for fertilizer-distributers. Fig. 2 is a view of the same as seen from beneath. Fig. 3 is a central vertical section of the sanie. Fig. 4. is a side view of the feeding-shell. Fig. 5 represents a modification of the same. Fig. 6 is an inverted view of the feeding-shell. Fig. 7 is a partial side elevation of the feedingshell. Fig. 8 is a plan view of aportion of the supporting-frame. Fig. 9 shows'the mode of attaching the distributer to the inside of the feed-cup. Fig. 10 is a section through the cleaner.

My invention relates to certain improvements on the feed-cup for fertilizer-distributers patented July 15, 1879, No. 217 ,628; and it consists in attaching the feeding-shell to the supporting-frame so that it may be readily removed therefrom.

My invention also consists in an improved form of the feeding-shell and in an improved clearer for preventing the fertilizer from adhering to the same.

My improvements in feed-cups for fertilizerdistributers are represented in the accompanying drawings, in which A is the feed-cup, which is provided on its lower side with a bevel-gear, B, meshing with a pinion, (shown in dotted lines,'G, Fig. 3,) by which the cup is rotated. 'D is the feeding-shell, which is provided with a projecting lip, E. The bottom of the feed-cup is provided with an opening of the same size as the interior of the feeding-shell, which opening is crossed by radial arms. (Sh, owfrin dotted lines at b b b, Fig. 1.) The radial ar'ms b b b are connected with a central ring, .0, Fig. 3, by which the feedcup is held in position on a hub, 01, which projects upward from\ the supporting-frame N. By means of this hub the feed-cup is held'in place on the'supporting-frame when the feedingshell D is removed. The feed-cup rotates in the direction shown by the arrows in Fig. 1, and the fertilizer in the cup, by the combined action of the distributing-rod F and the feedcup, is forced into the opening in the projecting lip' of the feeding-shell, from which it passes through the opening 6 in the supporting-plate.

In order'to remove the feeding-shell through the feed-cup the distributing-rod F must first be taken out. This I accomplish by fitting-one end of it into a hole in the side of the feed-cup and the other end into a right-angled slot, 1', Fig. 9, on the opposite side of the feed-cup. The end of the rodis passed downward through the vertical portion of the slot f, and is then moved sidewise until it bears against the end of the slot. The pressure of the fertilizer against the distributing-rod, when in rotation, holds it in place in the slot.

The feeding-shell D may be made removable from the supporting-frame in different ways, in each of which the shell is locked to the frame by inserting a lug into a recess and rotating the shell until it comes against a stop, in a manner substantially similar to that already described with regard to the distributing-rod F. The shell being arranged to turn in the same direction in which the feed-cup revolves, the friction on the shell will keep the same locked to the supporting-frame. In the accompanying drawings I have'represented' one-mode of accomplishing this result, in which the feeding-shell is provided with a central hub orboss, g, which passes downward through the supporting-frame, and is provided with a lug or lugs or pin, 6 'i, which pass through slots 01. n, Fig. 8, in the sides of the opening in the frame when the hub is inserted therein, and which pin, bearing against the projections o 0 on the supporting frame, prevents the further rotation of the feeding-shell. The surface .of the supporting-frame between the slot n and the stop 0 may be given an inclined or screwthreaded form, in order to secure the feedingshell firmly to the supporting-frame. This arrangement may be reversed, the hub being placed on the supporting -frame, passing through an opening in the feeding-shell. In this case a recess should be made on the top of the feeding-shell to receive the pin 1', so as not to interfere with the rotation of the distributer F, immediately above the feedingshell; or a right-angled recess for the pint may be formed on the inside of the opening into which the hub is inserted, whether the hub be placed on the frame or the shell.

In order to keep the opening into the feeding shell clear, I make the edge of the projecting lip E of the top plate of the shell with an inclination in the direction of the rotation of the feed-cup, as shown in the drawings. This edge is sharpened by being beveled from the inside of the shell. The edge of the flange 1), Fig. 7, which extends downward from the projecting lip, at the outside thereof, is also given an inclination in the same direction. It is also sharpened from the inside. The distributer F is so placed that in its revolution it will just clear the projecting lip E, which is elevated slightly above the surface of the feeding-shell. By this means any hairs or other fibers, such as are frequently found in commercial fertilizers, are prevented from catching on the edge of the lip and thus clogging the feeding operation.

In order to clear the corner between the lip and the flange p, a horizontal slot, r, Fig. 7, is made in the flange, and a cleaner, 1], is secured to the feed-cup in such position that in rotating it will pass through the slot 1.

The cleaner ll may be riveted to the feedeup, and its forward edge should be sharpened from its lower side, as represented in the sectional view, Fig. 3. The cleaner II is preferably inclined backward from the direction of rotation of the feed-cup, as represented in Fig. 6. It may be inserted in any part of the feedcup, and two or more of these cleaners may, if desired, be used.

Fig. 5 is a plan view of a modification ot' the feedingshell, the shell itself being shown in that figure in horizontal section below its top plate. An opening, I, in the side of the feeding-shell is substituted for the projecting lip, and a row of inclined feeders, L L L, attached to the rotating feed-cup, is arranged to feed the fertilizer into the said opening. Any desired number ofthese feeders may be employed at suitable distances apart. They may be either cast with the feed-cup or secured thereto in any convenient manner, and they should be inclined backward from the radius of the feed-cup, as shown in the figure. The feeders L L may also be employed with the projecting lip E if space be left for their rotation between the outer margin thereof and the interior of the feed-cup for their rotation.

The feeding-shell may be made with its top of a spherical form, either with or without the projecting lip. In this case the distrihuter F would be modified in form to correspond with the change in the feeding-shell.

The cleaner 11 serves to prevent the fertilizer from adhering to the under side of the projecting lip. The outer corner of the projecting lip extends beyond the top ot'the flange p, as shown in Fig. 7.

I claim- 1. The frame or bed N, provided with a hollow hub, combined with a rotating cup and hopper, and within said cup the feeder 1), provided with a stud,g, and pin or pins ii, which are adapted to pass down through said hollow hub and be locked below said bed by apartial rotation of said feeder and stud, whereby said bed, cup, and feeder are united and held in place without employing anydetachablc bolts or keys.

2. The revolving cup and hopper, combined with the stationary scroll-shaped feeder having a scroll-flange continuous from end to end, as described.

3. The bed or frame N, upon which the revolvin g cup is centered, provided with the hanging bracket-bearing, in the flanges of which are longitudinal slots to receive and keep in place the hubs of the driving-pinion, substantially as described.

4. The combination of the feed-cup A, feeding-shell 1), having projecting lip E, with slot 1 at its upper corner, and the cleaner H, adapted to tit the slot r, the whole constructed and operating substantially as set forth.
