l l i l I Application filed February 6,1882. (No model.) d

To all whom itmay conce t-n: i

Be itknown that we, WILLIAM ELI]. LYNN and GEORGE W. EYLER,of Staunton, Augusta county, State of Virginia, have invented a new and Improved Gornstalk Gutter and Crusher; and we do herebydeclare that the following is a full, clear, andexact description of the same, reference being had to theaccom pan yin g drawings, forming part of this specification, in which t Figure l isa top or plan view. Fig. 2 is afrontelevation and Figs. 3, 4, 5, and 6 are detail views. I a

Our invention relates to improvementsin eornstall; cutters and crushers; and it con sists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth.

In the accompanying drawings, a represents the frame ofour improved machine, in which is journaled the horizontal shaft b, carrying the circular cutter-head. 0, provided with one or more cutters, d, on its front face. The cutters d are straight, and are secured; to the front face of the cutter-head, so that the cuttingedge of each cutter shall startfroni a point, e, on the circumference of the head slightly below the-horizontal diameter j'g of the cutterhead,and thence be inclined upward to a point, h, on theyertieal diameter ij, from one to three inches above the center of the cutter-head, by which construction the cutters are straight and are not radial.

k To represent slots made in the cutterhead, and lying below and behind the cutters (l and parallel to their cutting-edges, for the passage of the cut cornstalks to the crushing devices.

Z represents a ledger-plate secured to the upper face of the frame a. The cutting-edge l of the ledger-plate is inclined downwardly and outwardly, or from the shaft b of the cutterhead, with its inner end, 1 highest and slightly curved up, for a purpose hereinafter described.

on represents a feed-box provided with a bottom inclined in the same direction as the cutting-edge of the ledger-plate.

n 12. represent two parallel standards, secured to the frame a and each provided with a vertical slot, n',in which slots is journaled the upper corrugated or longitudinally-fluted truncated conical roller, 0. longitudinally in the usual manner, and each The roller 0 is fluted projecting rib o has its apex planed off and its upper face provided with a smaller longitudinal flute, 0 whereby a better hold on the stalks is attained.

p 1) represent cyeholts, through thee-yes of which thejournals'of the upper roll, 0, pass.

q q represent spiral springs, each encircling an eyebolt, one end of each spring bearing against ajournal of the upper roll and the opposite end ofthe spring bearing against the upper and lower rolls, 0 s, are horizontal and parallel with each other, and in the same vertical plane parallel with the vertical plane of the cutters. The larger end of the lower feedcutter-head, and the upper rib of the lower feed-roll is in the same inclined plane or one parallel to the inclined cutting-edge of the ledger-plate. Thenpperandlowerfeed-rollers, o s, are arranged so that the larger end of one roller, s, is arranged toward. the center of the.

shall lie opposite the smaller end of theother,.-

as shown in the drawings. By this construction the axes of the conical rolls 0 8 may be arranged horizontally, and in the revolution of the cutters the inclined plane of the lower roll, .9, will offer a resistance to the passage of the cornstalks forced by the cutters (1 toward the center of the cntter head 0.

t represents a sprocket-wheel on the shaft 1), around which passes an endless chain, a, which also passes around the sprocket-wheel a on the horizontal shaft c, journaled in the frame a and carrying at its opposite end the beveled pinion w, which engages with the beveled wheel a, secured to the spur-wheel b on the shaft 0 of the. lower feed-roller, s. The spur-wheel 11 engages with the spur-wheel d on the shaft 6, which is connected with a sleeve, f, by a balland-socketj oint, the opposite end of said sleeve being connected by a similar joint with the inner end of the shaft of the upper feed-roll. The rear face of the circular rotary cutter-head is thickly studded over its entire surface with pyramidal teeth h, having a hollow or cupshaped topface, h with four projecting points, It. The teeth It on the rear face of the cutterhead are not arranged in concentric circles with concentric spaces between them for the passage of the stalks to be crushed, as in the ordinary construction, but are arranged at irregular distances from the center, and the spaces between the teeth are interrupted at short intervals by other pyramidal teeth.

l represents a stationary crusher-plate, with about onethird of its upper part cut away, adjustably secured to the frame a. opposite the cutter-head. The lower half of the crusherplate Z is thickly studded on its innerface in the same manner as the cutter-head, with pyramidal teeth m of the same construction as the pyramidal teeth h. The teeth h m on the cutter-head and crusher-plate are so arranged relatively to each other that the crushing of the stalks is done between the facial projections h of the teeth.

A represents a circular rim secured to the circumference of the crusher-plate and extending forward so as to embrace the circumference of the cutter-head. The function of the rim is to prevent the exit of the cut stalks before they have been crushed.

In practice the stalks are fed into the machine between the conical rolls 0 8 beyond the inclined cutting-edge of the ledger-plate, when the straight revolving cutters strike the stalks first at or near the circumference of the cutterhead, where the momentum is the greatest, and

from the above-described arrangement of the cutters a rotary and at the same time sliding out is imparted to the cutters, and also, by reason of this and the inclination of the cuttingedge of the led gcr-plate, a more acute angle is formed and retained throughout the entire out between the cutting-edges 0f the cutters and ledger-plate, whereby the stalksare more easily severed, the inclination of the ledger-plate and the under roll and the grip of the rolls preventing the stalks i'rom moving toward the center. The cut stalks pass through the slots in the cutter-head, and are immediately seized by and crushed between the facial projections of the pyramidal teeth on the surfaces of the cutter-head and crusher-plate, and pass thence out of the machine. The outer end of the ledger-plate, is made open, or with no obstruction to confine the stalks, and its inner end is made highestnand curved upwardly, as shown in Figs. 1 and 6, to prevent the stalks from being forced inwardly in the revolution of the cutter-head, and the cuttingedge of the upwardly-curved part Z is a continuation of the cutting-edge Z of the ledger-plate, so as to cut the stalks in con j unction with the cutters 11 when the latter revolve so that their cutting-edges come opposite the cutting-edges of the part l of the ledger-plate l.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination, with the rotary circular cutter-head c and straightcutters d, arranged thereon, as setforth, oftheinclined ledger-plate I, open at its outer end and provided with the inclined cutting-edge l and upwardly-curved inner end, I, having its cutting-edge in line with the edge l of the ledger-plate, substantial] y as described, and for thcpnrpose setforth.

2. The combination, with the lower longitiulinally-tlutcd conical feed-roll, s, ofthe upper adjustable longitudinally-fluted conical feedroll, 0, the apices of the projecting ribs of both conical rolls being cut away and provided with flutes, substantially as described, and for the purpose set forth.

3. The combination, with the cutter-head c, of the pyramidal tooth it, having a hollow or cup-shaped top face, h provided with the four projectin gpoin ts, h substantial l y as described, and for the purpose set forth.

4. The combination, with the cutter-head 0, provided with pyramidal teeth h, each having a hollow or cup-shaped top face, if, provided with projecting points h and arranged on its back face at irregular distances from the center, of the stationary crusher-plate 1, provided with similar pyramidal teeth m, similarly arranged on its inner face, substantially as described, and for the purpose set forth.
