To (LZZ whom it may concern.-

Be it known that I, WILLIAM C. HEIMER- DINGER, a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Corn-Knives 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.

My invention relates to improvements in corn-knives, the object of the invention being to provide a device of this character which will be of extremely simple in construc'tion and cheap to manufacture and which permits of the blade to be readily removed and the device thoroughly cleaned.

A further object is to so construct the device that no screws or other adjustable parts are necessary to secure the blade and in which the blade is compelled to assume its proper operative position, leaving nothing to the judgment of the user.

Vith these objects in view the invention consists in certain novel features of construction and combinations and arrangements u-l parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view illustrating my improvements. Fig. 2 is a view, in longitudinal sec tion thereof. Fig. 3 is a view in cross-section. Fig. 4 is a view of the kcife-blade removed, and Fig. 5 is a bottom view of the blade-holder.

1 represents a handle comprising a strip of sheet metal bent as shown to give an incline or tilt to the handle to properly draw the blade-holder 2 over the corn. The handle 1 and blade-holder 2 are made from a single piece of sheet metal and are given separate reference-numerals simply for convenience of description.

The holder 2, which is in operation disposed in a horizontal position, is provided along its sides and rounded end with flanges 3 to receive the blade 4. The side flanges are on a bevel to form a dovetail pocket for the blade 4, and the end flange limits the inward movement of the blade and insures its cutting edge being located at the proper place on the holder, and the latter is made with an opening 5 to permit the escape of cuttings.

The blade 4 is composed of thin sheet steel with rounded or straight cutting edge 6 at one end, and this cutting-end of the blade is wider than its rear end. In other words, while the blade is of uniform Width throughout the greater portion of its length, it increases in width as it nears the cutting edge, so that when the blade is forced into the holder 2, its cutting end portion being wider than the distance between the side flanges 75, this cutting end of the blade will be bowed slightly, so as to perfectly engage a corn and cut a slice therefrom, and by repeated operations of the device the corn can be cut down just as much as desired and without danger of digging too deep.

For convenience in assembling the blade in the holder or removing it therefrom I pro vide the blade 4 with a small hole 7, which is normally located below the opening 5 in holder 2. By inserting a pin or other device in hole 7 the blade can be forced out far enough to bring the wider end of the blade out of the holder, when the blade can be easily removed without danger to the user, and the parts can be thoroughly cleaned before reassembling. After being cleaned the blade can be inserted part way into the holder and a pin or other device placed in hole 7 and the blade forced back into operative position, the end flange of the holder serving to limit the inward movement of the blade and insuring its being left in proper operative position.

Slight changes might be made in the general form and arrangement of the parts de scribed without dep arting from my invention, and hence I would have it understood that I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a corn-trimming knife, a thin flexible blade having a cutting edge at one end and a holder having a seat for the blade and provided at its sides and forward end with portions projecting beyond said seat to receive the sides and forward end of the blade, said side portions cooperating with the blade to bow the latter transversely when it is inserted into the holder.

2. In a 'device of the character described, the combination with a holder having parallel flanges, of a thin sheet-steel blade to be forced between said flanges and said blade made wider at its cutting edge than the Width of the space between the flanges of the holder, whereby the blade will be bowed when forced into the holder.

3. In a device of the character described, the combination with a holder having parallel side flanges and an end flange, said side flanges being bent at an angle to form a dovetailed pocket, of a blade to be forced into said pocket and made widest at its cutting edge to bow this end of the blade.

4. In a device of the character described, the combination with a holder and flanges at the bottom of the holder to form a pocket, of a blade to be forced into the pocket and held in place by said flanges, and having a hole to receive a suitable device to force the blade into and out of the holder, said holder having a hole over the cutting end of the blade for the escape of clippings.
