Patented May 1, 1906.

Application filed September 8,1905. Serial No. 277.619.

To all 111710711, if 71mg concern.:

Be it known that I, I-IEMEN C. CHAPMAN, a citizen of the United States, residing at Leamington, Ontario, Canada, have invented certain new and useful Improvements in Corn-Huskers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the 'letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in corn-husking and silk-removing apparatus, and it comprises various details of construction and combinations of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

In carrying out the present invention it is my intention to improve upon my former patent, No. 743,450, and render the same more practical and efficient for uses for which it is devised.

My invention is illustrated in the accompanying drawings, forming a part of this application, and in which- Figure 1 is a vertical sectional view longitudinally through my improved corn-husker. Fig. 2 is a diagrammatic view showing the gear and sprocket wheel connections for driving the apparatus. Fig. 3 is an enlarged detail view of the portion of the apparatus which is provided to cut off one end of an ear of corn and sever the husks at the buttend thereof. Fig. 4 is a top plan view of a detail showing the mechanism for vibrating the hopper to cause the butt-ends of the ears to be fed foremost. Fig. 5 is a sectional view on line 5 5 of Fig. 1. Fig. is a sectional view on line 6 6 of Fig. 5. Fig. 7 is a detail view of one of the disks, having a circular cutting-knife thereon. Fig. 8 is a detail view of the yielding roller under which the ears of corn are adapted to pass.

Reference now being had to the details of the drawings by letter, Adesignates the frame of the machine, which is mounted upon suitable legs A, and B designates an endless conveyer, there being any number of said conveyers, as may be desired, which may be located side by side and on which the ears of corn are to be fed to the apparatus. Said conveyers are mounted upon the sprocketwheels B and pass over idlers B2. One of said sprocket-wheels B is driven by suitable belted connections with the driving apparatus. Each conveyer B is mounted in a suitable trough C and at intervals along the chain or lugs C, adapted to carry the ear of corn, butt foremost, along the troughs and deposit the same between the sectional disks D, which are of a construction substantially similar to those illustrated in my said former patent, and said disks are mounted upon a shaft DX, and intermediate the disks D is a circular cutting-knife DY. The shaft BX, which carries the inner sprocket-wheel B, is mounted upon the spring-arms BY, held yieldingly by springs Bz and provided for the purpose of allowing the inner end of the conveyer to yield to adapt itself to differentsized ears of corn.

Mounted upon a standard DG is a shakinghopper D7, pivotally mounted at D8, and D`J designates an arm carrying an antifrictionwheel D10, j ournaled therein, upon which the free exit end of the hopper rests.

D11 is a link one end of which is pivotally connected at D12 to the bottom of the hopper, as shown in Fig. 4 of the drawings, and the other end has a strap DI", which rides upon the eccentric D, 'fixed to the shaft D15, said shaft being driven by any suitable belted connections desired, whereby as the shaft is rotated a shaking movement may be imparted to the hopper, the bottom of which is inclined slightly forward and downward. The ears of corn (shown in Fig. 1) are placed upon the hopper, and the shaking -movement of the latter will cause the butt-ends of the ears to be fed forward upon the conveyer to be advanced into the machine for the purpose of husking the corn and removing the silk from the kernels.

E designates a circular outlined cuttingknife mounted upon a suitable shaft E, which is journaled in the frame of the apparatus and which is driven by means of a sprocket-chain E2, passing over a sprocketwheel E, rotating with the shaft E", which latter shaft also drives a wheel E5, positioned above the inner end of the endless conveyer.

F designates a shaft mounted in suitable bearings in the frame of the apparatus and has 'fixed thereto a pinion-wheel F', which is in mesh with an elongated gear-wheel F2, fastened to and rotating with the shaft F, which latter is also journaled in suitable X bearings upon the frame.. One end of the l shaft F'L carries a bevel-pinion F", which is in IOO IIO

' drawings.

mesh with a similar pinion F6 on the shaft F7, and a sprocket-wheel Fs upon the shaft F7 is adapted to drive a sprocket-wheel F9 upon the shaft F10, which latter shaft carries a sectional disk F11. Said shaft F has a longitudinal movement'and is normally held in the position shown in Fig. 1 of the drawings by means of a spring F13, which bears against a stationary member G, while its inner end is in contact with one end of the shell G, a dei tail View of` which is shown in Fig. 3 of the Said shell G, which is hollow, has a fiange g, with elongated slots g therein, and pivot-ally mounted upon said fianges are the two curved knives H and H, the endsv of said knives projecting beyond the circumference of said flange, and springs H2 are provided, one of each being connected to a lug H3 upon said fiange and its other end connected to one of said knives, as shown clearly in Fig. 3 of the drawings, the office of said springs being to normally hold the knives in t e position shown in Fig. 3 and spaced apart, it being understood that the inner concaved portions of said knives form cutting edges.

I designates a ring having two elongated slots I at positions diametrically opposite corresponding with the slots g in the fiange g. Rods I2 pass through the apertures I4 in the ring I, and nuts I5 are mounted upon the threaded ends of said rods. K designates a hollow ring, to which the other ends of said rods are fastened, and a spring K is mounted upon eachrod I2 and bears between the two rings I and K for the purpose of holding said rings normally at' their farthest positions from each other.

K2 designates fingers which are fastened to the inner face of the ring K at positions diametrically opposite each other and are adapted to register with the slots I and g, and each of said fingers has an inclined edge K5, the two edges being inclined, one on a reverse edge from the other, and are designed to contact, respectively, against the outer edges of the cutting-knives H and H as pressure is im- I parted to the ring K by an advancing ear of corn.

Fixed to a shaft L, which is journaled in suitable bearings in the frame of the apparatus, is a rubber-covered wheel L', whlch is positioned underneath the circular cuttingknife DY and spaced apart therefrom. A suitable sprocket chain LX, passing over sprocket-wheels L2 upon the shaft L and sprocket-wheel L3 upon the shaft L2 transmitsmotion from the shaft L to the shaft L4, and the shaft L is driven by sprocket-wheel and chain connections with the shaft Dx. A rubber roller L6 is fixed to the shaft L4 and is provided for the purpose of feedin the ear of corn against a rubber roller M, which is fixed to a shaft M, journaled in suitable bearings upon the frame of the apparatus and between the feeding-disks 0. One end of the shaft M has a bevel-pinion M2, which is in mesh witha similar pinion M3 upon the shaft M4, and a sprocket-wheel M5 is fixed to the shaft M4 and has a sprocketchain N 6, which passes over a sprocket-wheel M7 upon the shaft at the outer end of the conveyer C. N and N designate rubber rollers which are also fixed to rotate with the shaft M and spaced apart, as shown.

O O designate yielding section-disks which are fixed to the shaft O', and P designates a concaved brush to the lower end of a shaft P which is journaled in a pivotal angled bracket-arm P2, mounted upon the frame of the apparatus, a detail view of said mechanism being illustrated in Fig. 6 of the drawings, in which it will be observed that there are two of the concaved brushes P, mounted upon vertical axes, and a spring P3 connects the pivotal bracket-arms and is provided for the purpose of allowing the brushes to yield slightly to allow ears of different sizes to pass between said brushes. A bevel-pinion P4 is fixed to the upper end of each shaft P and is in mesh with a similar bevel-pinion P5, fixed to a shaft P6. The spaces between the teeth of the bevel-pinions P4 and P5 are of sufficient width to allow slight play, whereby the brushes upon the shaft P may move slightlj,T away from or toward each other.

Q designates a drag-brush which is mounted upon a yieldin arm Q and is provided for the purpose of holding the ear while it passes between the brushes P.

Q2 designates a wheel having a rubber periphery and xed to rotate with a shaft Q3, journaled in the frame of the apparatus and provided for the purpose ofv advancing the ear of corn between the rotary brushes P. The rotary brushes, traveling at a slower speed than the rubber-covered wheels which drive the ears, will cause the silk or husks to be brushed from the cob as the latter advances through the apparatus.

R designates a disk made up of yielding sections similar to the disk O,referred to, and is provided to advance the ear of corn to the rubber-covered wheel R, which is mounted upon a shaft R2, and S S designate concaved brushes which are similar to the brushes P and are mounted in the same manner upon shafts S, driven by the gear connections shown in Fig. l ofthe drawings.

T T designate the yielding sectional disks fixedto the shaft F10, and two of said yielding sectional disks, which are positioned parallel to each other and between which the earsof corn pass, are designed to force the ear between the rollers W W, which are provided for the purpose of removing any silk from the cob which might escape being'removed by the other brushes as the ear passes through the machine.

In operation the ears of corn are fed upon the hopper or shaker, and motion being im- IOO parted to the apparatus the vibration of the shaker will cause the heavy end of the ear te advance foremost, and being fed forward upon the endless conveyer the ears are first caught between the disk E3 and a roller upon the shaft at the inner end of the conveyer. As the butt-end of the ear comes in contact with the circular knife mounted upon the shaft Dx the inner faces of the sections of the feeding-disks upon either side of the circular knife will 'frictionally engage the ear, and as the ear is fed between the two circular eutting-knives DY and E it will be noted that the knives will cut into the ear and slit the husks along diametrically opposite portions of the ear. The butt-end of the ear being fed by the sections of the disk into the opening of the ring li and pressure coming against said ring will cause the 'fingers with inclined edges to pass through registering apertures in the rings I and g, and as said inclined edges come against the outer edges of the curved knives the latter will be thrown toward each other and quickly sever the butt-end of the ear and also loosen the husks from the ear. This mechanism for actuating the knives is so adjusted that the butt-end of the ear will be cut olf without retarding the movement of the ear, as its opposite end is carried downward by frictional contact of the same with the feeding-disks D. The ear of corn being fed down by said disks over the rubber-covered rollers L and L will be caught by the disks O and held against the rubber rollers M, which are arranged in pairs, with slight spaces intervening, and the ears passing between the disks O are forced under the drag-brush The ear of corn passing underneath said dragH brush is held by the feeding-disks R against the rapidly-rotating roller N, thence underneath a drag-brush X, mounted upon a yielding arm X, and passed between the rotary brushes S, and, finally, passed between the rollers XV by means of the di'sks T, by which mechanism the husks and the silk will have been thoroughly removed from the kernels of corn upon the cob.
