U TTE STA CLARK JACOBS, OF BROOKLYN, NEW YORK.
RICE-HULLEB.
To all whom it may concern:
Be it known that I, CLARK JACOBS, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Machine for Hulling, Cleaning, and Polishing Rice; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a top View of my improved rice-huller, some portions being removed to show others more distinctly; Fig. 2, a Vertical section of the same, in the line w, of Fig. 1; and Fig. 3, a vertical section, in the line y, of Fig. 1.
Like parts are designated by like letters in all the figures.
A, is a hopper, into which the rice to be hulled is put, and is conveyed thence by the spout a.
B, is a fan, of any suitable and known construction, for cleaning the rice at different stages of the process of hulling and polishing, as hereinafter fully set forth. The blast produced by said fan passes into the main pipe, or vessel, H; from thence a branch pipe I), conducts a portion of the blast through the unhulled rice, as it falls from the spout a, into the spout c, and blows away any impurities, which may be intermixed therewith, and which might otherwise clog or injure the rubber O.
D, is a stationary stone like an ordinary mill-stone. The rubber C, is constructed as follows ;-An iron LCllSli (Z, is firmly attachedto the shaft g, which drives it. Upon said disk a strong piece of leather of uniform thickness is laid and attached firmly thereto, by screws passing up through the iron disk, or other convenient manner. Upon this leather covering is cemented a thick disk of vulcanized gum-elastic or gutta-percha, which is the real rubber, for hulling the rice, when acting in conjunction with the stationary stone D. The shaft g, is made adjustable up and down by any suitable contrivance, and drives both the rubber C, and blower B. As the rice falls from the spout 0, it is completely hulled by the peculiar yielding and friction surface of the rubber C, acting against the stone D, without grinding or breaking a portion of the rice as other machines do. The rice, chaff, &c., passing from the huller through a space in the case G, are conducted by the spoutz', over the sieve j, (seen in Fig. 1,) which separates the rice-meal, tobe conducted by the spout is, to a receiver. From the spout 2', the rice and chaff fall into the spout Z, through which another portion of the blast comes, in the direction indicated by the arrow in Fig. 3, and blows away the chaff, while the rice falls into the spout m, thence into the conical wire case E, in which a brush F, of similar shape, revolves, and polishes the rice as it passes through. The brush F, is made adjustable up and down, in order to increase or diminish the space between it and the case E, as desired. The polished rice thence passes along the inclined groove 0, and into the pipe 7), through which another port-ion of the blast passes and blows away all the remaining dust and impurities. The rice then comes out by the spout s, in a beautifully finished state, and is ready for market.
I do not claim the use of india rubber surfaces for hulling the rice, such having been used before; but
lVhat I do claim as my invention and desire to secure by Letters Patent is 1. The use of a vulcanized gum-elastic, or rubber, or its equivalent, in combination with a stone or other equivalent non-elastic rubbing surface, for hulling rice; substantially in the manner herein set forth.
2. I also claim the manner of constructing the rubber C, of three substances of different qualities, viz,the metallic disk (Z, leather disk 6, and gum-elastic, or gutta percha, disk 7", by which firmness, elasticity and durability are combined, substantially as herein described.
The above specification of my improved machine forhulling, cleaning and polishing rice signed by me this 27th day of January CLARK JACOBS. WVitnesses HENRY P. DAY, WM. M. MEROHAND.
