IMPROVEMENT IN COFFEE-POLISHING MACHINES.
n Specification forming part of Letters Patent No. 129,947, dated July 30, 1872.
Specification describing a ne7 and Improved Coffee and Rice Hulling and Polishing Mai chine, invented by J OS GUARDIOLA, of Ghocola, in the Republicv of Guatemala, Central America.
Figure l represents a side elevation, partly in section, of my improved coffee and rice hulling and polishing machine. Fig. 2 is a top view of the same. Figs. 3, 4, and 5 are vertical sections of the polishing-stones.
Similar letters of reference indicate correspondin g parts.
This invention has for its object to improve the polishing-faces o f the rotary stones or articles between which coffee, rice, or other substances are placed to be polished or hulled.
In the drawing is represented the frame- Work A of a mill, similar in construction to the mills for grinding grain. B B are the two polishing or hulling stones or blocks. Their acting surfaces I propose to improve by applying to them a covering, a, of India rubber,
over which Wire-cloth b is stretched, as shown in Fig.- 3. The grain will 'be acted upon directly by the Wire-cloth b, Whose hard but rounded surfaces will suffice to remove the pellicles or polish the surfaces of the grains, but which will yield on the elastic cushion or support a suiiicient to prevent all injury to the grains. Instead of being of rubber the cushion c may be of matting or other elastic material.
A stone or block thus prepared will be far better for the purposes specified than the rigid surfaces heretofore employed in hulling and polishing machines. The chief difficulty to be .overcome in hulling and polishing machines was vto prevent the breaking of the grains While imparting the necessary degreel of friction. By the Vaid of the cushioned Wire surfaces this difliculty will be completely overcome.
It may in some cases only be necessary to have one of the blocks or stones prepared as above described, the other being a stone, as in Fig. 4, rou ghened or grooved at the polish- 'ing-surfaces, as usually.
The dark lines in Figs. 2 and erepresent a thicker Wire projecting a little over the Wire-` cloth b to form thereon lines of rounded projections diverging from the center to increase the roughness of the polishing-surfaces.
rI he improvement is applicable to the polishing-surfaces of all kinds of hulling or pol- 'ishing machines.
Having thus described my invention, I claim as new and desire to secureby Letters Patent- A The Wirecloth b arranged on the cushion a of the stone or block B, substantially as and for the purpose specied. e
