The elevator is operated by a belt, C2, from the iny.

It will'be seen that this apparatus is very simple and compact; that it can be Vmadre, very cheaply, and is not liable to get, out of order; also that, asit acts entirely by frictional contact of surfaces, the grain will not be cut or broken, and the operating surfaces are .so arranged that there can not be anygrinding of the rain.y v laving thus described my invent-ion,

I claim as new and desire to secure by Letters Patent- 1. A grain-decorticator, consisting ofthe cylinders A B and the spiral corrugated vanes or blades E K, combined, arranged and operating substantially as herein described.

2. The combination, with the cylinder `B andy the spiral blade K, of the corrugated disk 14", and the blades L, substantially as specified. V

3. The combination, with the cylinders Av B and the spiral vanes, of a hollow perforated shaft O anl an air-heating aml injecting apparatus X Y, the said I hollow shaft heilig alsoarranged for the admission of a steam-jet, ll substantially as specitied.

thereon.

The operation of this improved apparatus is as fol- A batch of grain is placed in the air-tight vessel, either through the supply-pipe, B, or any other suitable way; then the passage is closed; the pipe leading to the air-pump is then opened and the pump set in motion for creating a partial vacuum in the said airtight vessel; then the pipe leading to the pump is closed and the one B* opened, letting the air suddenly rush against the grain; this detachcs or partially detached the hulls from the kernels.

After this the passage from the bottom ofthe vrssel A is opened, andthe grain escapes to areceptac-le below, from which it is to bc raised by any means to the conveyer A, and thence through the elevator B to t-he cylinder A; here it is acted on by the corrusite end, where it is taken by the Scrapers H through lhe openings G into cylinder Bkaud exposed to the action ot'thc corrugated spiml 4blade or propeller K, which works it back again tothe other end, and against the corrugated disk F, until thrown out gential blades L; here it is acted on as before by the blade E, and these operations are continued as long 'as required for removing` the hulls by the frictional action of the surfaces ofthe several pari-s acti/ug on it. 5.
