Letters Patent No. 106,276, dated August 9, 1870.

IMPROVEMENT IN MACHINES FOR HSKING- CORN'.

The Schedule referred tain these Letters Patent and making part of the same.

port,.n the county of Goluinbia and State ot' New York, have invented certain Improvements in Corn- Huskers; and I do hereby declare that the' following is a full, clear, and exact description thereof', reference being had to the annexed drawing mnki ng part of this specification, in which- Figure l is a plan view of my improved machine.

Figure 2 is a sectional elevation on line x x, tig. l.

Figure 3 is a section of a detached portion on line y y of Iig. 1.

The same letters are used in all the figures `inA the designa-tion of identical parts.

This invention relates to machines for husking com, of the class wherein two sets of rolls are employed, one for stripping theears from the stalks and the other for husking the ears as theyare delivered f from'the strippingor picking-rolls.

The first part ot my improvement consists in forining, upon the surface of the stripping-rolls, right and left-handed screw-threads andl grooves of variable pitch, so arranged, with reference to each other, that the elevations of one are opposite the grooves in the other, to enable them to nip the ears from the stalk, and draw the latter, as it passes through them in 'a lateral direction, away from the point where .it is fed The second part consists in providing the bushingrolls each with one or more spiral depressions, of peculiar form, in their surfaces, which depressions, heilig left-handed upon one and right-handed upon the other rclland opposite to 'each other, receive the ear as it falls fromrthe picking-rolls, and allow it to settle down between the husking-rolls, so that the edges of the spiral bushing-surfaces shall have a continuous bite upon the husk.

' The third part consists in theapplication of an oscillating presser, in condection with husking-rolls, constructed as described, to gent-ly press upon the ears, as they pass along the surface of such rolls, for

the purpose ot' holding the ears iu firmer contact with them, so that the husk may be morecertainly grped by the edges of the lmskingsurfaces.

To enable those skilledjn the art to make and use my invention, I will proceed to describe its construction and operation. l

The frame A is made of strong timbers, and of suitable form and dimensions to receive and supportv the various operative parts to be mounted upon it.

The picking-rolls B B' are arranged across the front.

and in the upper portion of the trame, where their journals are supported in suitable boxes.

Springs or elastic cushions are arranged under the boxes ot one of the rolls in the usual manner.

The surfaces of the rolls are provided with spiral or screw-threads, running from end to end of' the same, and made of a variable pitch, by preference, as shown in the drawing. i

The threads on oneroli run in a reverse direction to those on the other, Aso that, as they are revolved,

and stalks of corn arefed in at one end, they will, in 'drawing such stalks through, carry them from theend where they are fed in to the opposite end, and there discharge them, thus permitting of constant and uninterrupted feeding.

It will be observed that the threads of one of the rolls are opposite the grooves in the other, and mesh into them, to allow them to take a firm hold of the stalks, and facilitate the nipping of the ears.

The depth and pitch of the threads will vary 'in accordance with the nature of the work to he performed by them.

The rolls are geared together by spur-wheels Bz and B, and may bc driven by any suitable power which should be applied to the unyielding roll.

v -The ears ofcorn, as they are nipped from the stalk, Adrop upon the husking-rolls C Cl, which are arranged transversely under and in rear of the picking-rolls, in au inclined position, as shown.

, They revolve, by their journals, in boxes arranged upon the cross-beams ot' the frame, they being geared together' by the wheels I) D', tovone of whichA 'the power is applied.

One of the rolls is made yielding, by placing its journal-boxes against springs or elastic cushions. I propose to construct these yrolls with one or more spiral depressions, C, in their surfaces, running from end to end, and in reverse directions along the respective rolls, so that', in revolving them, such de pressions come opposite to each other on the upper surface, and i'orm a bed into'- which the ear drops.

By making these spiral depressions in the rolls, a continuous spiral bushing-surface is obtained, so that such bushing-surface or surfaces will have a continuons bite upon the husk from the point to the but-t of the ear, and thus strip the husk oi1 at one operation.

Small points or teeth c may be arranged along the griping-edges of the hnsking-surtces, to assist in drawing the husk between them-,

T hold the ears, as they pass"`along the inclined bushing-rolls, infirmer contact -with them, I provide an oscillating presser, E, which may be constructed of a bar of iron, covered with an elastic or yielding pad, El, and pivoted, by arms E, to the cross-beams ofthe frame, by the side ofthe bushing-rolls, extending the proper distance above them, as shown in lig. 2.

One of the arms E2 is linked to a crank-pin on the journal of one of the rolls, to give to it an oscillating motion. e

I have shown only one set of husking-rolls, but'I propose to employ at least two sets, arranged side by side in the usual manner.

Where two sets are thus used, the presser will have a sufficient oscillation to press alternately upon the ears passing over euch set.

Having described my improvements in machines for hnsking corn,`

-Wlmt l claim, and desire to secure by Letters Potent, is-

1. The picking-rolls-B B7 when the'sztme are provided with spirztl threads and grooves, gearing with each other, and formed of variable pitch from end tov end, substantially as shown, and for the purpose described and set forth.

2. The husking-rolls C CI, when provided with spiral depressions G"l C upon their peripheries, and formed as described, substantially as n-ud for the purpose set forth.l

3. In combination with the husking-rolls C O, the oscillating presser-bar E, substantially as and for the purpose set forth.

ln testimony whereof I have signed my name to the foregoing spe'ciiioation in the presence of two subscribing witnesses.

PETER PHILIP.'
