` Letters Patent No. 93,124, dated July 27, 1869.

To all to whom 't may concm Be it known that we, THoMAs'Rosn, of Oxton, and

ROBERT EMERSON GIBSON, of New B-ighton, both in valnelss, known as 'coated seed,in such manner,

that the ke'nels or .oil-yielding portions can be easil separated from the husksand fibre.

. In its passagethrough .our machinery,'t he cottonseed is subjected to' a tearing-action, *of such a character that' the kemeis' are suflicientl'y^ disintegrated,- 01 g'onnd into meal, to allow of their easy 'emovai from' the h'usks and fibre, by sifting. I

The meal obtained from 'a given weight of -seed in this way, (and such meal is the desired prodnot,) will yield a larger quantity of oil, on being subjeeted to pressure or otherwise manipulated, than the whole' seed, treated in any usual way, would have given ont.

That the Construction and action or mode of operatio'n of our said machinery may be clearly seen and un-` derstood, and that others acquainted with mechanism for Operating on seeds may be enabled to make and carry onr improvements' into efi'ect, we'will refer to Figures 1, 2, 3, and'4, on the sheet of drawings hereto attached, premising that in all these views like letters denote the same parts, I

Figure 1 represents a view in longitudinal elevation,

Figur@ 2, an end elevation,

Figura 3, a plan, and e Figure 4, an end View of' one of the segments forming the circumference of the breaking-rolls.

A denotes the supporting-hame.

This consists of side-pieces a and ties a'.

B B', plumber-blocks, adjustable by the set-screws- I), bushed, to carry the shafts O- O'of the 'breaking-up serrated rolls.

These rolls are here shown constrncted with radial arms 0,0 and circnmferential rings e e whereto segmental pieces 0 with serrated snrfaces are bolted. One of these segmental pieces is shown full size by fig. 4, and the form of teeth which answers best is' illustrated.

Although we prefer. to construct the rolls in segments, as iron and steel can be easily cast into that form in chill-moulds,vit will be obvious the said rolls can be cast in one or more 1engths,with the Serrations, or the ser'rations can be formed afterwards, in chill-monlds, or otherwise.

To make the circumferences'of the said rollsrotate at difl'erential speeds -and such speed of rotation is of great importance, as rcgards bra-thing qnantity, for by I is subjected to a dragging-tear-they are geared by and over pulleysf f& on the ende of the amis-of the .it up, the distance between them being temperedto it theiseed, in passing between the serrated surfaces,

toothed wheels D and D', secured on c and o of different diameters. j V

In practice, we prefer a speed 'of four to one in the surface of the rolls; but We do not confine ourselves to' any speed, whether dfi`erential or the same. Instead, however, of obtaining it by gearing'of difi'erent' diameters, we may make the rolls themselves. of different diameters; but this we do not consider so eificacious 'as the arrangement just described and shown on the drawings.

E is the driving-pulley, receivin'g motion from any convenient line of shaft-ing or power.

To keep the serrated sui-faces clean, we employ cylindrical brushes F F', of coir or other' strong fibre, and make them rotate by bands or cords f, passed over pulleys f f on the endsv of the axis of e o brushes.

When the said machinery or machine isat work, the cotton-seed is fed from the hopperZ, to or between the sen'ated rolls'. These, as they rotate to-' wards each other, as indicated by the arrows, so break the size and condition of the seed,by the screws b, that when the gross product of kernels, in the state of' meal and husks and fib'e, is diseharged nnderneath,

it is only necessary to employ ordinary sitting-screws,

to remove the'meal.

The shallowness of the indentations in the rolls, and the great obliqnity of the surfaces of these indentations, greatlyfacilitate thedischa'gc of the crushed' seed, and rendor the etfectof our machine very dit ferent from that of any machine with projectin g pins, or with any analogous -deep or rectangular 'spaces between the projections. Our machine will serve in some cases without clogging, even if the brushes F F' are o'mitted, or are not operated. But we esteem it much-better to employ the'brushes in combination, in allcrdiary conditions of the kernels, and hnsks of the seeds. y e

Having 'now described the nature of oursaid invention, the constructionof the machinery, and the man- 'ner of 'employing the same in practice, we would have it understood, that what we claim as of our inventien, is-

The shaliow notched rolls and hopper, as specified, combined and arranged relatively to each other and to tne clearing-bmshes F F' as herin set forth. v

In testimony whereof, we have 'hereunto set our names, in presence of two subscrihing witnesses.
