To a whom, it may concern:

Be it knownthat I, J oHNW. LANE, a citizen of the United States, residing at Portland. in the county of. Oumberlaud and State of Maine,-h'ave invented certain newand useful Improvements in Rice-Hulling and Cleaning Machines; andI dohereby declarethe IOUOW- ing to be a mu, clear, and exact description of the invention. such as will enable others I0 skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a part of this specification. v H

r This invention rel ates to'machinery for hull- 7 ing and cleaning rice; and it consists in certain novel constructions and combinations of devices, .which will be fully understood from the following description, when taken in conmotion with the. annexed drawings andclaims. A represents a'cylinder, about six feet long and about thirty inches in diameter, provided with projections onribs a on-the inside, as shown. On the outside of. this cylinder A there is a gear, b, around it .at one end, -as shown clearly in Fig. 1, which is driven by a pinion, b. It also has two rings, H H, near its ends, adapted to run in grooves of the wheels 0 0,,on both sides of and beneath the cylinder A, on which the latter is supported and revolves. These wheels prevent endwise movement of the cylinder, andthe bearings of said wheels are mounted on a suitable base, F, of the main frame. The cylinder A is held down in place on wheels 00 by means of grooved wheeled d and rodG, fixed to the stationary heads Aw at cylinder; There is a perforated cylinder, B, inside of the cylinder A, and of the same length, which is mountedupon ashaft,B, having spiders uat its ends,'and at intermediate points between .naled in the boxes of the heads A A, andalso its ends to which'said cylinder B is fastened, asshown in Fig. 3. The projections or ribs a, on the. exterior of the cylinder B, I call wipers, and their purpose is to impart blows to the rice. They are beveled, so-as to give draw-strokes and direct the rice 'tangentially outward against the beveled ribs a on the outer cylinder, A, and they are numerously perforated, to present roughenededges. The shaft B, inside of the cylinder B, extends a sufiicient distance beyond itsend to receive a driving-pulley, R,which is belted, to receive motion from any suitable prime motor.

.At the ends ofthe cylinders A B are the cast-iron heads A A above referred to, fitted ted against said ends, so that the cylinder will run rice-tight thereat; The shaft B is jour- 7 in a box'upon the end of a stand, L, resting upon the floor, as shown in Fig.3. One of the heads, A, has ahopper, J, for feeding the rice into the space between the inner and outer cylinders, A and B. In this hopper is a valve, J, fonregulating the supply or feed. On the same head is an opening, which commu nicateswith a pipe, S, and the space between the two cylinders, (shown in-Fig. 3,) leading to an exhausting engine orfan, V,driven from the large pulley by means of a belt, o. By these means the dust, &c., is drawn from the cyli'n- V ders A B as the rice is cleaned. Y In Fig. 2 I. show the train of gears bywhich motion and proper speed arelcommunicated-8 5 to the outside cylinder from the main shaft B through the medium of pinionwheels b b. 1 Through the headA is a passage, T, for the escape of the hulled and cleaned rice, which dischargeis regulated by'a va-lve, t. I o Figs. 1 and2 show the pinion b which em 7 gages with the gear b, and rotates the large cylinder A, which pinion is'j keyed on the shaft of a" large spur-wheel, b, that receives motion from'the main shaft B V 5 Through the heads A A are openings W, for the free admission of air to the interior of v the machine, so that by the action of the exhaust-fan V currents of air will be drawn, through the cylinders, and remove the dust,

&c., from the rice during the hulling process.

What I claim, and desire to secure by Letters Patent, isj .1. In a rice hulling and cleaning machine,

the combination of the rotary imperfora-te cylinder A, having a discharge-passage, 1, and internal beveled ribs, (1, the perforate rotary cylinder B, provided with external wipers, a, beveled and perforated, a feed-passage for the rice, and a suction-fan, communicating with the space between the two cylinders, substantially as described.

2. In a rice hulling and cleaning machine, the combination of the internal perforate rotating cylinder having the perforated and beveled wipers, the external imperforate r0- tating cylinder having internal beveled ribs. the stationary heads for both cylinders, provided with feed and discharge passages for the rice, and an air-exhausting device, substantially as described. a

3. The combination of an exterior cylinder having a positive rotation, and an interior perforate cylinder geared thereto, and having perforated beveled wipers on the exterior thereof,

substantially as described.

4. The combination of a rotary externalin 1 perforate cylinder having ribs 011 the interior thereof, a rotary perforate cylinder having perforated and beveled wipers on the exterior thereof, fixed heads A A", provided with air-inlets and feed and discharge passages for the rice, and means for inducing blasts of air through the cylinders, substantially as described.

5. The combination of the external rotary cylinder, A, provided with bands, the grooved wheels, and stationary heads, with the internal perforate cylinder, 13, provided with perforate wipers a, the spiders and main shaft, gears for driving both cylinders from said shaft, and means for inducing a blast of air through the cylinders, substantially as described, v

Intestimony whereof I affix my signature in presence of two witnesses.
