GEORGE H. FETZER, OF WOODBERRY, MARYLAND.

CORN-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 389,066, dated September 4, 1888.

Application filed March [6, 1888. Serial No. 267,341.

To aZZ whom, it may concern:

Be it known that I, GEORGE H. FE'rzER, a citizen of the United States, residing at Wood berry, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Oorn-Outting Machines, of which the following is a specification.

My invention relates to a corn-cutting ma chine, the object of which is to provide asiniple and eflicient machine whereby green corn may be cut rapidly and cleanly from the cob; and the invention consists of a novel construction and combination of parts, substantially as hereinafter described, and set forth in the claims.

The accompanying drawings illustrate my invention, in which- Figure 1 is a plan view of a corn-cutting machine cmbodying my improvement, parts being broken away. Fig. 2 is a longitudinal side view of the same. Fig. 3 is a sectional end elevation on the line y y in Fig. 2.

In carrying my invention into practice the base A of the machine is provided with up right bearings 13, in which are mounted to turn longitudinal tubular shafts C, the bore of each of which is adapted to form an easy passage for the corn-cobs after the kernels have been removed. One, two, or more tubular shafts may be employed.

On the rear end of each tubular shaft 0 is mounted a bevel-gear, D, which is engaged by a corresponding bcvehgear, E, on a drivingshaft, F, which latter is provided with a pulley, G, to be rotated by a beltfrom a convenient source of power.

The forward open end or mouth, H, of each tubular shaft is made daring, and is provided with a frame consisting of three radially-projecting arms, I, having forked extremities, in which are pivoted corresponding levers K, having heads K on their outer ends and guideslots M in their inner ends. In the present instance three radial arms are employed, but obviously one, two, or more may be used.

The heads K on the end of the radial arms have square sockets in which are held radially-adjustable cutting-knives I, which converge at their inner cuttingedges in front of the flaring mouth of the shaft 0. These several knives are separated at the edges to per- (h'o model.)

init the passage of the corncobs into said flaring mouth. The knives are held by set-screws O in the arm-heads.

The cutting-edges of the knives P are sharpened and curved on a bevel. Springs P are coiled on radial rods 1?, which are fixed to the outside of the shaft 0 and project through the said slots M in the knife-holding levers K. By this construction the cutting-edges of the knives P will be pressed upon the ear of corn fed between them, so that as the knives rotate they will remove the corn from the cobs, while permitting the cobs to pass into the tubular shaft, from the rear ends of which they issue.

Two scraping-plates, Q, are mounted and are movable so as to slide on each frame I directly in front of the flaring mouth H. The plates Q have curved-out or concaved edges 1-, and one plate overlaps the other,with the two concaved edges confronting each other and forming a central opening, a, through which the coins pass from the knives P. The plates Q have transverse parallel slots, in which are stop and guide pins or screws Q, fixed to the frame I. Springs Q are arranged on said frame in connection with the scraping-plates, so as to press them together, and thus clean and scrape from the cobs anykernels remaining after the knives have done their work. The scraping-knives will yield to allow for variations in the size of the cobs.

The cars are fed small end foremost, so that the scraping-plates Q, will close behind the tapering large end of the cob and prevent the same from being withdrawn.

A feeding mechanism substantially as shown is employed. In the present instance it consists of spears S, each one of which is fixed in line with the mouth H of a tubular shaft to a bar, T, which is part of a horizontally-sliding frame. Rods T are attached to the bar and slide in bearings T", and a cord, 13, is attached to each rod and passes over a pulley, t, anda weight, U, is suspended at the lower end of a cord. Each ear of corn is placed with its buttend or large end against a spear S, which holds the car from turning, and the ear-carrying spears are forced automatically toward the cuttingknives. After each ear or set of cars are cut, as before described, the bar and spears are withdrawn by hand to permit the application of other ears to the spears for like treatment.

Any ordinary or approved form of clutch or kindred mechanism may be employed for starting or stopping the rotation of the knifecarrying frames without stopping the main driver.

Having described my invention, I claim 1. In a corn-cutting machine, the combination ofaspear, S, mounted on a movable bar, a revoluble tubular shaft, 0, mounted in bearings and provided at one end with a gearwheel and at the other end with a frame having radial arms I, levers K, pivoted to said arms and carrying radial knives P, two plates, Q, each having parallel slots and one overlapping the other and both loosely secured to the said frame by screws Q through the slots, and a spring pressing each loose plate.

2. In a corn-cutting machine, the combination of a rotary shaft having a longitudinal tubular passage for the corn-cobs, self-adjusting knives attached to and converging in front of the open end of the tubular shaft, and a corn-ear feeder consisting of a spear pointing toward the knives and mounted on a movable frame provided with a weight to press it toward the cutter, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

GEO. H. FETZER.
