Patented Nov. 6, 1860.,
Inveni-or:
N. PETERS. momumm mr. Wuhingmm n. c,
UNITED STATES PATENT OFFICE.
DYER GREENE, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND JOHN H. W. PAGE, OF SAME PLACE.
RICE-HULLER.
Specification of Letters Patent No. 30,604, dated November 6, 1860.
To all whom it may concern:
Be it known that I, DYER GREENE, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Mill or Machine for Hulling and Cleaning Rice; and I do hereby declare the same to be fully described in the following specification and illustrated in the accompanying drawings, of which Figure 1, is a side elevation, while Figs. 2, and 8, are cross sections taken in planes at right angles to each other.
The principal parts of this rice mill consist of a screw and a mortar, the former being made to revolve within the latter. In these respects, the machine is not new, my invention consisting in an improved arrangement of the screw, its shaft, and the pivot and stop of the latter with respect to the bottom and the discharging valve or valves of the mortar.
Heretofore, the shaft of the screw has been pivoted in a step placed within the mortar, and there has been between the screw and the said bottom one or more spaces or cavities of such depth and form as to render it difiicult if not impossible for the screw to act on and elevate all the rice, unhulled portions of which would be clogged or remain at the bottom of the vessel and be discharged with the hulled rice, and by becoming mixed therewith would endamage its appearance more or less. Furthermore, by having the shaft step within the mortar, the lubricating matter necessary for such step is not only liable to soil the rice, but it is very difficult to keep the step and its pivot clear of the rice and dust. It is also inconvenient under such circumstances to apply oil to the step.
In carrying out my invention, the shaft of the screw is to be extended entirely through the bottom of the mortar and be pivoted in a step outside of the mortar and supported by a hanger or its equivalent arranged underneath the bottom of the mortar. The lower end of the screw is brought so close down to the bottom of the mortar and the upper surface of each gate thereof as not only not to break the kernels of rice while the screw may be in revolution but to cause such screw to so act on them as to effect their elevation off the bottom in a manner to prevent any portion of them from becoming stopped or clogged under the screw as occurs when the shaft step is arranged within the mortar and the screw does not run close down to the bottom and the gates of such mortar.
In the drawings, A, exhibits the mortar which consists of an oval or egg shaped vessel, having a flat bottom, a provided with a cylindrical hole, I), at its center, such hole being for the passage of the shaft, B, which carries the screw, C. The said shaft is pivoted at its lower end or part, c, in a step, D, arranged outside of the mortar and supported by a hanger, E, arranged as shown in the drawings. On. opposite sides of the hole, 6, there are two discharging openings cl, cl, made through the bottom, a, each of the said openings being provided with a gate or closing valve, F, applied to a lever, G, the valve being so applied to the lever that when the valve is closed, its upper surface may be in the same plane or even with that of the bottom, a.
The shaft of the screw, 0, carries a bevel gear, H, which engages with another such gear, I, fixed on a driving shaft, K. When the latter shaft is put in revolution, the shaft, B, and its screw, C, will be rotated within the mortar and provided such mortar be charged with rice, the screw acting in conjunction with the inner surface and bottom of the mortar and with the top surface of the gate or gates will raise the kernels of rice from the bottom and create such a current through the mass as will operate not only to hull but cleanse each kernel thereof.
I do not claim for the purpose of hulling and cleansing rice, a screw and a mortar or vessel constructed, applied and operating together as represented in the United States Patents Nos. 17,646, and 17,882, as in such applications of the screw and mortar, the shaft of the screw is pivoted in a step arranged within the mortar and extending above its bottom so as to form an obstacle and the discharging valve or valves F, of the t0 the movements of the rice, and to be obmortar. jectionable in other respects.
I claim DYER GREENE. 5 My improved arrangement of the screw, Witnesses:
O, its shaft, B, and the pivot and step D, B. H. EDDY,
of the latter With respect to the bottom, a, F. O. HALE, Jr.
