CORN-HUSKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 621,919, dated March 28, 1899.

Application filed December 31, 1897. Serial No. 664,999. (No model.)

To all whom t may concern.-

Be it known that I, RICHARD J. HOLM- GREEN, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Corn-Husking Machines, of which the followingisafull,

clear, and exact description, such as will enable those skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification The invention relates to improvements in corn-husking machines of that class consisting, essentially, of two jaws pivoted together, one of which jaws carries an anvil and the other a knife.

It has for its object the provision of a device of simple and cheap construction and efficient in its purpose.

The invention consists in the novel con struction, combination, and arrangement-of parts, such as will be hereinafter fully described, pointed out in the appended claims, and illustrated in the accompanying drawings.

In the accompanying drawings, in which similar letters of reference designate corresponding parts, Figure 1 is a perspective view of a corn-husking machine embodying the invention. same. Fig. 3 is a similar view taken from the side opposite to that shown in Fig. 2, and

Fig. 4 is a sectional view on the line 4 4 ofv Fig. 2.

Referring to the drawings by letter, A designates the support on which the machine is mounted, and it may be of any construction suitablein the premises. Secured to the support is the base B. The latter has bifurcated lugs b projecting from its opposite sides. Bolts b engage with said lugs and pass through the support, and thereby secure' the machine in place. The base has considerable length, and when the lugs b are taken into consideration it has considerable breadth. The base therefore has considerable bearingsnrface on the support, and thereby allows a iirm attachment of the machine to the support.

On the base B and preferably made integral iherewith is mounted the arm C, form- Fig. 2 is a side elevation of the.

ing the upper and xed jaw of the device. The said arm projects outwardly and upwardly from the base. Its outer end is substantially straight and horizontal. From its vupper edge a narrow flange c projects and forms a rest or seat for the back of the knife c2. The latter is secured in place bythe bolt c3, passing through the same, and the arm O. The knife is made quite strong and stout to serve its purpose to the best advantage. It has an angular cutting edge c4.

From the base B and preferably made integral with the same the lug or extension D projects. It extends to a distance somewhat more than one-half the length of the upright part of the arm O. So far as it projects the lug is parallel with the arm. In the lug, near its upper end, is an opening d. In the arm C is an opening c5 in line with the opening CZ.

Between the arm O and the lug D is pivoted the lever E. The outer end of the lever forms the lower and movable jaw of the device. An angular flange e projects transversely from the outer end of the lever. Its upper surface is corrugated and forms the anvil against which the knife c2 cuts.

Intermediate of the ends of the lever E is a lug e', provided with an opening e2. Through the opening e2 and the openings 'c5 and d a bolt e3 passes and pivots the lever between the arm O and the lug D.

The end of the lever E opposite that carrying the anvil is turned down and forms a stop e4. The latter serves to limit the upward movement of the anvil, so that when the latter and the knife are brought together considerable space will intervene between the cutting edge and the corrugated engaging surface. In the operation of the device it is not necessary for the knife to impinge on the anvil, and by providing a means for preventing the two from coming together the cutting edge of the knife will be preserved.

From the side of the lever E shoulders e5 project and form a seat for the handle F. The latter is seated against the lever between the shoulders and is secured in place by the bolt f, passing through it and the lever.

It is to be observed that the angularity of the corrugated anvil is substantially the same as the angularity of the cutting edge of the knife. The purpose of the angularity and the IOO corrugation is to enable the knife to better penetrate the husk and to secure a better hold than itwould if the cutting edge should be straight and the engaging surface of the anvil straight also and not corrugated. The corrugated engaging surface of the anvil allows the knife to make an indentated cut, and consequently is more easily forced into the husk.

It is obvious that changes may be made in the embodiment herein described Without departing from the spirit of the invention-for instance, the anvil-carrying jaw may be fixed and the knife-carrying jaw lnovable.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a corn-husking machine, the combination of a base, an arm mounted on said base, a knife having an angular cutting edge secured to the outer end of said arm, a lug projecting from said base adjacent to said arm, a lever pivoted between said arm and said lug, an angular flange projecting from an end of said lever and forming an anvil adapted to coperate with the angular outting edge of said knife, means for moving said lever, and a stop for limiting the movement of said anvil relative to said knife.

2. In a corn-husking machine, the combination of a base, an arm mounted on said base, a knife having an angular cutting edge secured to the outer end of said arm, a lug projecting from said base adjacent to said arm, a lever pivoted between said arm and said lug and having an end turned to form a stop adapted to engage with said base to limit the movement of said lever, a corrugated angular flange projecting from said lever and forming an anvil adapted to cooperate with said knife, and means for moving said lever.

In testimony whereof I hereunto aiix my signature in the presence of two Witnesses.
