SPECIFICATION formingpart of Beiscued Letters Patent'No. 10,001, dated January 3, 1882.

Original So. 218.759. dated August 19. 1879. Application for reissue filed August 6, 1881. I

To all whom it may concern Be it known that I, Enwtu D. MEAD, a citizen of the United States, residing at Shortsville, in the county of Ontario and State of New York, have invented certain new and useful Improvements relating to Machines for- Applying o'r Sowing Fertilizing Material; and

I do hereby declare that the following is a full and exact description thereof. v

The invention consists in a fertilizer-distribnter having a horizontally-rotating feed-wheel arranged in the bottomof the hopper and a discharge-orifice arranged near the periphery, in combinationwith a hinged or pivoted gate adapted to work over the mouth of the orificeto regulate theguantity to bedischarged.

The invention also consists in a fertilizerdistributer having a series of horizontally-rotatin g disks or feed-wheels arranged in the bottom of the hopper and -a series of discharge orifices arranged near the peripheries of the feed-wheels, in combination with a series of hinged or pivoted gates adapted to work over the mouths of the orifices and pivoted to a common connecting-rod, whereby-the series of gates may be simultaneously operated to open, close, and regulate the quantity tobe discharged.

The invention also consists in a novel mode of constructing the hopper-bottom and revolving the feed-wheel therein.

The invention also consists in a horizontallyrotating fertilizing-distributor mounted on an axis, combined with a revolving scraper or cleaner mounted on an independent axis.

Other features of my invention will he more fully and specifically set forth in the description of the accompanying drawings..

In the accompanying drawings,"Figure 1 is a top plan view of the horizontal feeding devices and adjustable'gates for regulating the quantity of distribution. Fig. 2 is a sectional elevation, showing the operative parts of the device. Fig.3 is a bottom plan view'of my improvement attached to the hopper of the machine. Fig. 4 is a plan view,.representing a modification.

One of the commonest forms ot' fertilizing material which it is desired to apply to land by means of myjmachine or analogous machines is a powdery superphosphate of lime. This material is liable to become, by the shakingof the machine, very closely compacted together. In damp weather it is liable to form a hard cake. It is important to provide means for keeping it from bridging and for clearing or cleaning the surfaces of the distributing machinery. The main part which is liable to become clogged is the wheel or corresponding device, which is provided with recesses and is partially immersed in the pasty mass.

A is the'hopper, which contains the superphosphate to be distributed.

B B are castings formed witheircular openings adapted to Tee-cite the feed wheel D.

Around each of thecircular openings is a vertically-projecting flange, B, with a horizontal flange, B, adapted to supportthe wheel D by its periphery, as. represented. The under face of each wheel I) is formed with asries of beveled-gear teeth, D, placed immediately within the peripheral bearing. These engage with corresponding driving-pinions, E, on the driving-sh'al't'E, which latter is supported in' suitable bearings, B", on the fixed frame-work of the machine, and receives motion through.

the pinion E from gearing on or connected with the driving-wheel. (Not represented.)

The upper face of the wheel D may be plain or may have ribs extending from its spaced projections 0 toward the center. The whole face of the feed-wheel carries the phosphate. The cavities or recesses between these projections 0 serve as convcyers. They are filled by their rotationnnder the mass of powdery fertilizer, and bring the material from distant points to the immediate vicinity of the discharge-orifice H.

A spider-frame or bridge-tree, B formed in one piece with or fixed on the casting B, extends across under each wheel "D and forms a firm support for the axial journal (I, on which wheel D revolves, and forms a support for" the bearings 13, in which the transmitting- A yoke frame or arch, B is finnlyfixed-to each casting B.

shaft journals. also cast on or It serves as a support for a stout pivot or axle, g, on which turns a clearing wheel, Gr;

form and functions of this clearing wheel G and its mode of mounting are peculiar. Its lower face runs close to the upper face of the wheel D. Its axis 9 is slightly inclined, so that it bears only at the periphery of the wheel D. It is formed with wings analogous to cogs, which engage with the projections (J on the upper face of the distributing wheel D. These compel theclearing-whcel Gto revolve and the.

win gsof the wheel G to act as crearer's to force the superphosphate oil from the face of the feed-wheel. The wings are beveled, as shown. The projections O are correspondingly beveled. i

Indamp weather the superphosphate islia ble to become pasty under a kneading action. \Vhen thnsconditioued it will pack if the form of construction is not carefully attended to. The beveled edge of my scraper-wheel scrapes the surface of the feed-wheelandlifts the phosphate, as it is forced to the orifice for discharge, 4

sutficiently to keep it from packing. As the machine is drawn over the ground the shaft E is rotated by. the power received from the driving-wheel, and, being provided with pinions E corresponding to each distributing-wheel D, gives a continuous rotatory motion tothe entire set. Each wheel 1), being geared and pivoted shown, receives a strong uniform motion, its pin 0 keeping the superphosphate above; stirred up in the immediate vicinity of the wheel. Theupperpartof thernass is saved from any agitation and kneading. No particle-becomesstirred until the material below ithas been so far consumed as to let itdown into thevicinity of the feed-wheel. Then it is certaih tih be agitated by tlierevolution of the wheetD under it and by the action of the pin or pins 0 projecting from its upper face. The projections (J stand favorably-situated to re U ccive the phosphate, and by the rotation ofthe wheel to convey into the vicinity of the discharge-orifice H a liberal supply of the sup'erphospltate. The clearing-wheel G stands favorably situated to scrape the whole upper surface of the feed-wheel, and also by its beveled wings to act between each of the beveled projections O, and to force out all the superphos fihat'e which may be contained between the said projections.

Jis aigate turning on a center j, fixed in the casting B, and adapted, when properly placed, to. cover the whole of the dischargeorificfl, aud by adjusting will feed out any desired quantity as the distributing-wheel D brings around into the neighborhood of the orifice Hifa supply of the phosphate.

It will be seen that if the gate Jis so nearly closed as to allow but little ofthe, phosphate to pass through the orificethewings of the clearing-wheel G, being beveled,"litt the balance, and it remains undischarged."

, The frontface of the gate J, adjacent to the distributing-wheel D, has a high hip. This serves to crush any lumps of phosphate which may have been formed and brought around into the proper position. The revolution of the wheel G, in acting on such lumps, instead of pushing them off radially over, the upper surface of the gate, mashes them against the front lip, J, and the whole or a portion of each.

lump is dropped down the discharge-orifice.

Each gate J J has a long lever, J, which is connected by a pin, k, to a rod, K. This rod K extends across the machine and iscontrolled by the attendant. --It may beheld by a. pinchin'gscrew, or otherwise, in any desired position in which it is adjusted. This single rod K,

therefore, adjusts all the discharge-gates-of the entire series. So also the ratio of the size of the clearing-wheel G to the distributing wheel D. may be varied.

It will be understood that there may be some I approved form of mechanism worked in the adjacent hopper M for distributing seeds, and that the seeds may be sown. broadcast or conveyed down tubes, either with the fertilizing material or indepen dently, as may be preferred.

I have not deemed it necessary to represent" pensed with. The discharge-orifice is in the center of the distrihating-wheel.

The great mass of the fertililizing material is prevented from falling through this by any convenient means, as a cylindrical casing ora circular plate covering the main part of the hole, and leaving a sufficient orifice at the side adjacent to the clearing-wheel.

The motion may be imparted to the annular feed-wheel in the same manner as above, and the action of the wings and the clearing-wheel G will act by the beveled edges and wings to clear the spaces between the projections U in the same manner as alread y described; but in this case they will work from the exterior inward. The pivot or axis on which the wheel G turns is in this case outside of the distrih uting-wheel instead of within its area. The

bevel of the projections 0 must. in this be on the outer instead of the inner edges of the projections G.

The parts may be made with .suiiicient accuracy with little or no finishing by tools. With an ordinary geod fit between the periphery of the feed-wheel "D and the vertical flangefBQwhich surrounds it, and the flange E, which u'nderlies it, a little lubricatingma,

ter'ial applied at intervals serves not'only to relieve thcfriction, but also to inake and main-- tain'a tight joint, and prevent anytescape-Oi.

the fertilizer around the feed-wheel;

It will be observed that; my construction al lows-the pin orarm O to move freely around,

in combination withthe clearer G, and withgi out interfering with it. I In passing the clearer the pin applies in one of the notches therein. The notched form of my clearer is important in providing for the passage of the pin O; and 5 It also serves a useful function in communicab ing the proper rotatory motion from the wheel D by means of the projections U engaging therewith. The projections O in this case perform the double functions of conveyers to inport the loose material lying thereon to the delivery-hole H, and also of teeth torotate the wheel G; but some of the benefits of my in vention might be obtained by rotating the clearer G' by other .means. Machines for sowing or distributing have been heretofore made with a horizontally-revolving feed-wheel. In these, however, the feed-wheel is located within the bottom of the hopper, or when it forms itself a portion of the bottom it is. suspended below the bottom by a central shaft. By this invention the feed-wheel itself forms part of the bottom of the hopper, and is supported at its rim by a. depending lip and flange on the portion surrounding the aperture in which it is placed. v

I claim- 1. A fertilizrr-distributer having a horizontally-rotating feed-wheel arranged in the bottom of the hopper and a discharge-orifice arranged near the periphery, in, combination with a hinged or pivoted gate adapted to work over the mouth of the orifice to regulate the' quantity to be discharged, substantially as set forth.
