PEVA-THRASHER AND COTTON-OPENER.

SPECIFICATION forming 'part of Letters Patent No. 293,098, dated February 5, 1884.

' Application filed July 31,1883. (No model.)

T at whom it may concern..-

Be it known that I, CALVIN H. Srmroxs, of Munford, in the county of laladega and State of Alabama, have invented a new and Improved Pea-Thrasher and GottoirOpener,

of which the following is a full, clear, and exact description.

My invention is for thrashing peas and other grain, and also for beating, opening, and

cleaning seed-cotton to prepare it for the gin.

by removing dirt, gravel, nails, and other matters injurious to the lint and damaging to the gin, besides being dangerous on account of causing the gin to strike fire, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is partly a side elevation and partly a sectional elevation of my improved machine, and Fig. 2 is a sectional elevation of the machine on the line :0 0a of Fig. 1. a

I provide a thrashing and beating device consisting of the perforated sheet-n1etal or woven-wire concave a, having spikes or teeth 6, and the revolving shaft 0, having other teeth, d, which teeth I prefer to bend or curve reversely to each other, as shown in Fig. 2, to hold the straw, lint, and other matters and break or open them more effectually, and particularly to' collect and hold the vines above and away from the perforated bottom and walls of the case, keeping the perforations open, and thereby causing a better separation of the peas from the vines. Into this thrasher I supply the pea-vines and other grain to be thrashed directly through the feed-opening c in the side of the case, which consists of a vertical extension, f, of the concave above the heater to the extent of two or three times the diameter of the beater, which extension is continuous over the top, and is not perforated.

Vhen the machine is to be used for beating and opening seed-cotton, I prefer to apply a trough, 71., to the beater-case, said trough be: ing perforatedor reticulated, and containing a revolving shaft, 2', with beater-arms j, preferably set spirally, and increasing in length toward the inner end of trough h. By the arms j the cotton which is fed into end opening, 71, of the trough, is to be first treated to and other refuse matters, after which it passes through spout it into the concave a, tobe still a slight beating-process to expel the sticks thrashed, the grains are to escape from the concave through the perforations of the same, while some broken and partly-thrashed stems and heads containing grain, and being too heavy to be discharged along with the straw, pods, and other light matters by the fan, will escape through the opening at 0 through one end of the concave provided for a passage for them.

For operating the machine, the beater-shaft 0 will have the main driving-belt applied to a pulley, p, on'it,-and said shaft will have a cone-pulley, q, to drive the fan by another conepulley, s, to vary the speed as required; and when the cotton-beater ij is employed it will be driven by a belt, I, from a pulley on the beatershaft c.

The machine is to be constructed in differ ent sizes, and is designed to work lightly and not very fast, to cause a kind of grinding action rather than the common high-speed thrashing motion, especially when used for treating cotton, so that it may be worked to ad,- vantage by hand-power, that may be applied by a hand-crank to be fitted to the square extension a of the shaft 0. I also propose to employ the machine, in connection with mowing and reaping machines, for thrashing peas at the same time that they are harvested, by attaching it to the machine and gearing it so that the grain will be delivered directly to it from the reaper by an elevator or other approved means, and a suitable receptacle will be provided for the grain to fall into from the concave a.

I proposeto construct the concave a so that teeth I) may be added and removed, as may be required for diiferent'kinds of grain or for 2 memes thrashing cotton, which may be treated better with less teeth, While peas may require more.

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

1. An end-rounded oblong case, f, provided with perforations and curved teeth I) on the bottom, and an opening, 0, at one end, near the bottom, in combination with reversely-curved teeth (1, arranged on a rotary shaft, to intermesh with teeth I), and a suction-fan communicating with said' case near the top of the latter, as described.

2. The combination, with a bottom-perforated oblong case, f, of the connectedp'repar- '15 and'then remove the lighter particles, as de- 20 scribed. V
