ROBERT BRYSON, OF SGI-IENECTADY, NEW YORK.

CORN-HUSKEB.

Specification of Letters Patent No. 18,385, dated October 13, 1857.

To all whom it may concern:

Be it known that I, ROBERT BRYSON, of Schenectady, in the county of Schenectady and State of New York, have invented cer tain new and useful Improvement in Corn- I-lusking Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1 is a longitudinal vertical section of my improvement; the plane of section being through the center. Fig. 2 is a plan or top View of ditto.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to certain improvements in a corn husking machine formerly patented by me.

The invention consists in the employment or use of a cutting device arranged and operating as will be hereinafter shown, whereby the butts are readily cut from the ears before the same are subjected to the husking rollers.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a rectangular frame on the upper part of which a horizontal endless= apron B is placed. This apron works over rollers (a) (a) and has transverse bars (3)) attached to it at suitable intervals, the bars (7)) being parallel with each other; In Fig. 1 twoseries of bars are shown with the spaces (0) (0) between them.

C is an endless apron which works on rollers (cl) (d) which are fitted in heads (6) on the frame A. This apron C is provided with teeth (9).

D, D, are two rollers, the peripheries of' which are corrugated longitudinally. These rollers are placed one over the other in the sameplane, and the periphery of the upper roller is kept in contact with the periphery of the lower roller by springs which are placed over the bearings of the upper roller.

E, E, are two rollers which are placed directly back of the rollers D, D, the rollers E, E, have corrugated peripheries and are precisely similar and are arranged the same as the rollers D, D.

F, F, are two rollers which are placed at the outer side of the rollers E, E. The upper roller F has a smooth periphery but the lower roller F, has spiral knives attached to it, the periphery of the upper roller F being pressed down upon the edges of the knives by springs (j) which are placed over the bearings of roller F.

To the front sides of the heads (6) a bar Gr is attached. This bar has two openings (k) made transversely through it. These openings are of conical form. In the back side of the bar G a steel plate (Z) is fitted, and thisplate has openings (m) (m) made through it, the edges of the openings at one, or bot-h sides being brought to a cutting edge.

The outer end of the plate (Z) is attached to one end of a lever H which has its fulcrum at (a). The opposite end of this lever is fitted in a earn 9) which is placed on one end of the inner roller (a) of the apron B, see Fig. 2.

The rollers of the two endless aprons as well as the corrugated rollers are all connected by gear wheels and all the rollers receive motion from the driving or power shaft I.

The operation is as follows: Motion is given the power or driving shaft I in any proper manner, and the cam (p), and lever H gives a reciprocating motion to the plate (2'), the attendant puts the but-ts of the ears, shown in red, in or through the openings (70) in the bar G, and the butts are nearly but not quite cut from the ears by the cutting edges after openings (at). Two butts are cut at the same time, and this cutting of the butts loosens the husks or causes the ears to be readily detached from them, be cause the husks are attached to the butts and the butts are attached to the ears, consequenly if the butts are detached or cut from the ears, the husks may be readily stripped from them. hen the butts are cut, the ears are placed upon the bars (6) of the 'apron B, and are conveyed to the fluted rollers D, D. These rollers strip the husks and butts from the ears, the butts being carried between the rollers E, E, and partially crushed thereby. The butts then pass between the rollers F F, the knives on the roller F cutting the butts and rendering them suitable for fodder or food for stock. Thev husked corn passes down be tween the inner end of the apron B and the lower roller D, the ears of corn drop from the apron as they are husked, the bars (2)) allowing them to drop therefrom as they pass around the inner roller (at). These bars serve as regulators and do not allow the ears of corn to remain on the apron after they are husked. The bars also cause the ears to be retained on the apron till the husks are stripped from the ears. The rollers D, D, rotate or move much more rapidly than the apron B, and the apron B moves faster than the top apron C.

This machine has been practically tested and operates well. By cutting the butts partially off from the ears the rollers D, D, are enabled to strip the husks more readily from the ears, and the operation is rendered much surer, while the toothed bars (2)) convey the ears to the rollers D, D, and cause the ears both large and small to drop from the apron as they are husked.

By means of the rollers F, F, and cutters the butts, which are now considered worthless in consequence of a hard external shell or covering, are rendered suitable as food for stock.

I do not claim the endless aprons B, C, and corrugated rollers D, D, E, E, for they, in connection with a guard, have been previously used and were formerly patented by me; But,

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

The reciprocating plate (Z), placed in the bar G, and having apertures (m) made through it, and provided with cutting edges, substantially as shown, for the purpose of cutting the butts from the ears; the bar G having apertures (76) made through it, and the bar (Z) operated as shown or in any proper manner.
