LLOYD G. STALNAK-ER, OF YORK, PENNSYLVANIA.

FERTILIZER-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 333,263, dated December 29, 1885.

Application filed May 18, 1885. Serial No. 165,890. 1N0 model.)

To aZZ w/wm it may concern:

Be it known that I, LLOYD O. STALNAKER, acitizen of the United States, residing at York, in the county of York and State of Pennsyl- Vania, have invented certain new and useful Improvements in Fertilizer-Distributors, of which the following is a full, clear, and exact description.

This invention relates to machinery for use in sowing or distributing fertilizing material of the usual sorts, and has special reference to the feeding device for ejecting the material from the hopper or box. In this class of agricultural machinery the actual outlet or dis charge. has heretofore been both lateral and central, and it is in this latter form of machine my invention resides.

The invention consists in a feeder having a stationary throat, forming the discharge-orifice, in connection with the usual boot, a stationary bottom for the hopper or box, a rotary toothed feeding-cup arranged wholly below such bottom, and having the throat for its bearing, and a scraper and regulator, constructed and arranged as hereinafter more particularly set forth and claimed.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1 is a top plan View of my feeder; Fig. 2, a similar view with the top plate removed; Fig. 3, a vertical section in the plane of line 00 m, Fig. 1; Fig. 4, a similar section in the plane of line 3 y, Fig. 1. Fig. 5 is a similar view in the plane of line a a, Fig. 1, and Fig. 6 is a perspective view of the scraper or regulator, detached and on a larger scale.

The frame, box or hopper, boots, and other fixtures (not shown) may be as in any of the approved fertilizerdistributors, or combined distributers and drills or seeders or attachments therefor. The plate a forms the bottom of the hopper or box, and is provided with a semicircular opening, b, having the downturned lip c, and the scraper d, the latter intersecting the lip diametrically.

e is the throat, provided with the collar f, and closed at the top by a cover, 9, having the braces h, which engage the walls of the hopper, said cover having an observationgate, z, movable, to permit a view of the inside of the throat and its appurtenances to inspect the operation of feeding, and for other purposes. This throat is supported by the driving-shaft j, which extends through it, and is bushed therein by the hubs of the pinions k Z,

the former being fast on the shaft, and the latter being an idler held in place in any suitav f below the bottom plate, a, and provided with a toothed annular flange, n, depending from its bottom, with which the pinions k l engage, the former to rotate the cupm, (so hereinafter designated,) and also incidentally to support it, and the latter serving solely as a support for said cup, so that said cup may be freely rotated around the throat e, as upon a fixed journal. To a horizontal portion, 0, of the cup is secured in any suitable manner, as by screws or lugs and slots, an annulus, p, having projecting from its internal edge, horizontally, a number of feeder-teeth, q, the active faces or edges of which are beveled, said vteeth serving asstirrers or feeders to carry down the fertilizer through the opening I; in the bottom a into the cup m, and aid in discharging it into the throat. The scraper d .co-operates with the upper surface of the teeth q to keep them clean, as indicated in Fig. 5.

A rail or guide-bar, r, is secured horizontally.

in the throat 6, about on alevel with the lower end of its collar, and upon this rail is mounted, to slide back and forth through the opening e, a scraper, s, to regulate the quantity offertilizer discharged, and to keep the cup and under side of the teeth'from choking or becoming clogged. This scraper in detail is composed of the flanges s s, to engage the rail 1" within the throat e, the segmental finger s, adapted to be projected more or less out into the cup m, through the opening 0 in the throat, and having the vertical face 8 to meet the fertilizer as it is carried around by the teeth (1 and cup, and deflect it into thethroat through the opening e in greater or less quantity, according to the extent of the projection of said scraper into said cup,and the post 8, provided with means to engage an operating lever or bar, t, passing through the upper end of the throat. It will be understood that these feeders may be applied in any number to the machine, and that the shaft 7' will serve to operate the Whole series, and the bar or lever t will be connected to all of the scrapers; adjacent surfaces of the lip c and the ring 11 are matched so as to form as close a joint as possible, to prevent the sifting of the fertilizerbetween them. The bottom a also makes a tight or close joint with the throat, so as to restrict the descent of the material to the opening b, and the collar f so covers the bearing of the rotary cup upon the throat as to make a tight joint there. 7

It will be noticed that with my construction the feed is from the outsideinward, the active members (teeth q) being arranged upon the border of the material, rather than within it, and acting upon it from without. This is advantageous for many reasons, but chiefly because the machinery has to rotate or move a less superposed mass, and hence the draft is not so heavy, and there is less strain upon the: moving parts. 7 a

What I claim is 1. In a fertilizer distributer, a feeding device comprising an annulus having internallyprojecting teeth to act upon the mass from its outside, substantially as described.

2. In a fertilizer-distributer, a feeding device comprising an annulus having internallyprojecting teeth to act upon the mass from its outside, and a rotary cup to which it is attached, substantially as described.

3. In a fertilizer-distributer, a feeding device comprising an annulus having internallyprojceting teeth to act upon the mass from its outside, acup to which it is attached, and acentral throat encircled by said cup and annulus, and having a lateral inlet from the cup, substantially as described.

4. In a fertilizerdistributer, a throat provided with a lateral inlet, a feeder cup, and

toothed annulus encircling it, a driving-shaft passed through and supporting such throat and geared with the cup to rotate it about the throat, and means to control the quantity of material discharged from said cup into said throat, substantially as described.

5. A feeder having feeding devices, and a shaft and pinions to operate them, said shaft and pinions also serving to support the said feeding devices, substantially as described.

The

6. The stationary throat, and rotary feeding devices encircling the same and utilizing said them, substantially as described.

7. The plate a, forming the bottom of the hopper or box, and having the opening b, lip c,'and scraper d, combined with the feeding mechanism arranged beneath said plate and in close contact therewith, substantially as described.

8. In a fertilizenfeeder having a dischargethroat, a surrounding cup to contain the material to be fed, and a feeding device, the scraper arranged within the dischargethroat, and having the finger s, and adapted to be moved back and forth, as required, to vary the quantity fed, substantially as described.

9. In a fertilizer-feeder, the discharge-throat provided with a cover and lateral braces secured to the hopper-walls to stay the upper end of the throat, substantially as described.

' 10. Inafertilizer-distributer, the dischargethroat provided with a cover, and an observation-door set in said cover to permit inspection of the progress of the feeding operation, substantially asdescribed.

11. The discharge-throat having a lateral opening, and a movable scraper adapted to be projected more or less out through said opening, combined with a surrounding feed-cup into which said scraper enters, and means to feed the material to be distributed into said cup, substantially as described.

12. Ina fertilizer distributer, a central throat supported by the drive-shaft and stayed above, and having an external collar, a cup encircling said throat and having a bearing upon it and up against the lower edge of its collar, and rotated from and supported by the drive-shaft, a dentated feeding-annulus borne by the said cup, a regulator or scraper to control the quantity discharged from the cup into the throat, and a bottom plate superposed upon the cup and having a bearing upon the upper edge of the collar, substantially as described.

In testimony whereof I have hereunto set my hand this 16th day of May, A. D. 1885.
