IMPROVEMENT IN CORN-STALK CUTTERS.

Specification forming part oi Letters Patent No. 124,401, dated March 5, 1872.

To all whomit may concer-n:

Be it known that I, SAMUEL WALTERs, of Dallas City, in the county of Hancock and State of Illinois, have invented a new and valuable Improvement in Corn-Stalk Gutters, and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a pa-rt of this specification, and to the letters and figures of reference marked thereon.

Figure l ofthe drawing is a representation of a vertical longitudinal section of my invention; Fig. 2 is a top-plan view of the same.

This invention has relation to corn-stalk cutters; and the novelty consists in the construction and arrangement of devices for giving a vertical chopping motion to the knife, of devices for raising the knife above obstacles, and keeping it in a uniform position.

In the accompanying drawing illustrating this invention, A represents a rectangular frame mounted on two driving-wheels, B B'. O designates a spur-Wheel secured to the rotating axle of the wheels B B', and turning with it. D represents a shaft holding a slid- 'ing pinion, E, which engages with the spurwheel O and a crank-arm, D', which is coupled to a lever-arm, E', pivoted to one end of a rocking ba-r, F. G designates a frame hinged to the frame A. Secured to it is a bracket, H, to which the rocking bar F is pivoted and -works on as on a fulcrum. The end of said bar, opposite the arm E', is coupled to a link, I, which supports a vertical rod, I'. The knife J is secured to the lower end of said rod in a horizontal transverse position, the cutting-edge below. The rod I' works through a guidingbracket, i, attached to and projecting from the middle longitudinal bar of the frame A. The vertical chopping motion of the knife is caused through the medium of the pinion and gearwheel, acting through the intermediate devices referred to and described. K represents a clutch-arm pivoted to a backet, K', and designed for the purpose of throwing the gearwheel and pinion into and out of gear. L indicates a bell-crank pivoted underneath the inner end ofthe frame G.A It is connected, by means of a rod, L1, to a foot-lever, L2, within reach of the drivers foot, M being the drivers seat. By pressing the lever L2 forward the frame G may be raised so that the knife may pass over obstacles. One arm of the bell-crank should be curved so as to work against the under side of the frame G with ease. N designates a friction-roller for keeping the knife in a steady, even position, and prevent it from being thrown out of place by obstacles. Said roller is journaled to the end of a bent arm, N', extending back from the frame G, to which it is attached. O represents'a pressure-roller, arranged in front of the knife. It is journaled to a pair of arms, I?, hinged to the forward end of the frame A.

I claim as my invention- The frame G hinged to the frame A and supporting the rocking-bar F, in combination with the bell-crank L, rod L1, and foot-lever L2, or other equivalent operating devices, substantially as specified.

SAMUEL WALTERS.
