IMPROVEMNT IN MACHINES FOR HUSKING CORN.

Specification forming part of Letters Patent No. 101,809, dated April 12, 1870; reissued August 16, 1870, No.

4,099 reissued November 8, 1870, No. 4.1711.

To all whom it lmay concern Be it known that I, L. Aries. AsPINwALL, ofthe city and county of Albany and Stateof New York, have invented certain new and useful Improvements in Corn-Huskers; and I declare the following speciication, with the draw-Y ings forming a part thereof, to be a full and complete description of my invention.

Figure 1 represents a perspective view ot' the machine, with a portion ofthe top and side broken away. Fig. 2 represents a cross-section of the husking-rolls and cutters. Fig. 3 represents a section of the gear-wheels used upon the rolls. Fig. et represents a plan view of the rolls modified as hereinafter described. Similar letters denote similar parts of the apparatus.

A A A `is the frame ot' the machine.

T is the top or table.

Fis theband-wheel upon the shaft, on which is the picker-roller D, having its surface grooved angular. Above this, and in combination with it, is the plain roller E. These serve topick or remove the ears ot' corn i'rointhe stalks. Upon the same with the ily-wheel is the gear-wheel H, connecting with the pinion H, which gives motion to the basking-rolls RR by means ot' bevel-gears underneath.) Not shown in the drawings.) The husking-rollers R R are placed upon an incline, as in most machines. f

B B are boxes in which the rolls revolve.

U is the inclined plane upon which the ears are conducted to the rolls. Beneath this is another pair ot' boxes, which support the upper ends ofthe rolls; also, a pair of double gears, which connect the rolls. (Not shown, owing to their small size, but may be seen in Fig. 3, L L).

S S are the sides. K

I I are the beveled sides to insure the keeping ofthe ears lengthwise ot the rolls.

Fig. 2 is a section ofthe rolls R 1t and the purpose of keeping' the rolls free from hnsks.

The method ofhusking corn by means ot' rolls, as well as picking it from the stalks, is no new thing. Rubber rolls ot various constructions have been used, also rubber and iron combined, but theylack durability. Iron rollsprovided with teeth upon the surface have been used, but they shell the corn. Grooved rolls rcaused by pressions be made eccentric, but may be at or varied in any way, so as not to form a groove that will become iilled with gum. The eccentric form is merely a. matter of convenience in turning them in a lathe in their manufacture. These rolls when in rotation will present between them alternately an open space and a closed contact of surfaces. The open space the depression is for the purpose ot' allowing the ear ot'corn to drop down into it, and in closing rto suddenly impinge upon the covering or husk to detach a portion ot'it and carry it downward between the cylindrical sur faces as they roll together, and thus draw it oli'. These depressed rolls are provided with teeth P P, set inpone side ot' the depression, so as not to inipinge upon the ear until the cylindrical surfaces pass their points ot' contact and let go their hold of the husk, thus preventing the shelling ot' the corn. rollers ot' small diameter, with only one depression on the periphery, but they may be made larger and have more; but as long as they Vpresent the alternation of open spaces between them and the rolling contact ot' cylindrical surf'aces'they will work Vin the same manner. 'lliedepressions|nay,ifmadelarger, be all in one roll, Iand the other roll be made cylindrical, yet operate in the saine manner. Huskingrolls provided with Ateeth are liable to become wound around with husks, and cannot beremoved with Scrapers. 1t is therefore necessary to use cutters, asseen in" Fig.

The gear-wheels used upon the basking-rolls ot'all machines must necessarily be small; consequently are are liable to break quite often, To avoid this the gears L L, Fig. 3, are used, which are double, and may be tripled or quadrupled,

having teeth opposite the spaces in each, which gives a constant bearing upon the pitch-line l prefer subject to a heavy strain and' and insures a stronger wheel from the fact of there being double the number of teeth. Althoughthisis not newinitself,theimprovement consists in the application to bushing-rolls The operation of the machine is thus: The power being applied to the Wheel F, gives motion to the picker-roller D, and by means of the gear-wheel and pinion H motion is communicated to the rolls R R, all in the direction of the darts. The stalks then being placed upon 'the table T, are fed butts irst between D and E, Where they are carried along and the ears pinched olii, dropping them upon the rolls R R, where the husks are removed and the ears delivered at B B.V i l v What I claim as my invention is` t 1. The husking-rolls R R, when provided (one or both) with depressions r, formed substantially as shown, and for the purpose 'set forth.

2. In combination with the rolls R R, vconstructed substantially as described, the double gearsY L L, as and for the purpose spectied and set forth.

3. In combination with the depressions r, of the rolls R B, the teeth P, as and for the purpose described.

4. The combination and arrangement of the knives M M Withthe rolls E R, constructed substantially as shown, and for the purpose set forth. Y

5. The employment, in a machine for husking corn, of bushing-rolls Working together in pairs, provided with alternate depressions on their peri'pheries, formed substantially as shown in cross-section,Fig. 2 of the drawings,

and arranged to operate substantially as described, and for the purpose set i'orth.
