JAMES WV. PARKER, OF VIOLA, ILLINOIS.

CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 471,889, dated March 29, 1892. Application filed July 27, 1891. Serial No. 400,898. (No model.)

To all whom it may concern.-

Be it known that I, JAMES W. PARKER, a citizen of the United States, residing at Viola, in the county of Mercer and State of Illinois, have invented certain new and useful Improvements in Corn-Harvesters; and I do 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.

This invention has relation to a cornstalk cutter, and is designed as an. improvement upon the devices shown and described in the Letters Patent granted to me September 8, 1874, No. 154,765, and December 1, 1874:, No. 157,292, respectively.

The novelty will be fully understood from the following description and claims when taken in connection with the annexed drawings, in which Figure l is a perspective view of my improved device. Fig. 2 is a front view with the heel-clamp removed. Fig. 3 is a front View showing the implement attached to a foot and in an operative position. Fig. 4 is an edge View of the heel-clamp, showing a modification; and Fig. 5 is also an edge View of the heel-clamp removed. Fig. 6 is a perspective view taken on the side opposite to that of Fig. l with the standard partly broken away.

Referring by letter to said drawings, B indicates a standard carrying at its upper end a shield F, which is suitably secured to said standard and preferably by the employment of an intermediate cross-plate Ct. The shield F, which is designed to be fastened to the leg of the operator at a point below the kneejoint, is curved or concaved to conform to the limb, as shown, and is provided at its ends with loops for the reception of the securingstrap D. The standard B is bent outwardly and thence inwardly, as shown at P, and a brace-arm a extends obliqu ely downward from the outer side of the curved portion of the standard and is secured to the blade or cutter, as will be presently explained. This standard has its lower end curved or bent inwardly transverse, as shown at Z, to receive the heel-clamp.

A indicates the cutter. This cutter comprises a blade of a sufficient length and width, having its cutting-edge straight and tapering upwardly and outwardlyfrom its heel f to its point J and is secured at its inner end to the standard, as shown. It will be observed that the blade is secured to the lower end of the curved portionPof the standard, which standard is not only curved outwardly at this point, but also curves rearwardly, so that the cutter is brought slightly in rear of the journal portion Z of the standard, while the point J of the blade is brought considerably forward in an elevated position from the heel f. By this arrangement of the cutter having the upward tendency the operation of cutting is much facilitated, the slope of the knife holding'the same in line with the body when the foot is held toe outward in its natural position for walking, so that the knife is prevented from losing its hold while cutting.

C indicates the heel-clamp. This clamp may be formed from a single piece of material, as shown in Fig. 5 of the drawings, having its rear end bent upwardly at z and screwtapped to receive a screw e, which is preferably provided with an eye a to receive an implement for turning it, and the impinging end of the screw is preferably pointed, as shown. This clamp is provided near its opposite end with a transverse bearing eye g to receive a transverse branch Z of the standard, so as to .form aflexible connection therewith, and

above this bearing-eye are provided forwardly-directed teats or points z" to pierce the for- Ward side of the'heel, and at the extreme forward end of this clamp are provided laterallydisposed loops 1), which are designed to come at a point below the shank of the shoe to receive a securing-strap E, designed to buckle over the instep, or approximately so.

In some instances I provide the rear end of the clamp-plate with a groove and place therein a screw-tapped block Z insteadof'forrning this screw-tapped branch integral with the plate, and as it is sometimes desirable to attain more adjustment for the clamp than can be accomplished by the screw e I may make that portion of the clamp carrying the lateral loops b, the teats or prongs z", andthe bearing 9 in a separate piece and adj ustably secure the same to theforward elevated portion (1 of the plate by means of a screw or bolt and nut h and similarly connect these parts at the flat intermediate part of the plate 0.

These connected parts may be slotted, so that they may be adj ustably secured together.

Having described my invention, What I claim is V 1. Thecorn-harvestingimplement described, consisting of a standard having its lower end bent inwardly and also bent outwardly, rearwardly, and inwardly at a point intermediate the ends of the vertical portion, a cutter secured to said intermediate bent portion and having its cutting-edge straight and tapering laterally oblique from its heel to its point, and a heel-clamp hinged to the lower end of the standard and carryinga strap for attachment over the ankle, substantially as specified.
