IMPROVEMENT IN MlDDLlNGS-PURIFIERS.

Speccation forming-part of Letters Patent No. 144,697, dated November 1B, 1873;L application filed November 1, 1873.

To all whom it may concern:

Be it known that I, GEORGE PARKER, of Poughkeepsie, `in the county of Dutchess and State of New York, have invented a new and Improved Middlings-Purier, Of which the following is a specification:

sectional elevation taken on the line :u of

Fig. 1, and Fig. 3 is a cross-section on the A represents a rectangular case or chest, such as commonly is used for such machines, on the top of which, near one end, is afunnelshaped receiver or hopper, B, which 1s to be A placed directly under the floor on which the pile of middlings lies, the floor having a hole as large as the top of the funnel, or thereabout. In the Opening of the funnel at the lower end, which is at the top Of the case, is a revolving conefeeder, C, nearly lling the opening. This cone, which is in practice made adjustable vertically to Open the passage more `or less, is'provided with grooves in the sides,

which facilitate the feeding by scraping off the mass lying upon the cone regularly, and producing an even stream. It is revolved by gearing D at the lower end, connected out side of the case with the shaft E, which gears with the main driving-shaft F. Immediately under the cone is the upper end of the upper sieve G, which is a flat shaking sieve hung by hooks H at the'upper end to the wall of the case, and at the lower end resting on the cams I, which lift it and let it fall at each revolution. N At the lower end the coarse matters escape into the space J, `to be blown out of the another sieve, if required; but as two ar'e suiii cientV for ordinary use they are deposited in the conveyer 0 below, to be discharged at the spout P. The coarse light matters from the lower sieve also escape o' the end at the space J, and are blown out of the case. These are A ag ;aj n separated into two grades by the plates Q and R and the passage. S, which turn the heavier portions downward, while the lighter portions pass over and beyond. In practice,

the sieves will be suspended at the upper ends l so as to be shifted higher or lower tovary the of different qualities and conditions. The cams are arranged on short shafts, T, extending through the case and' gearing at one end with the vertical shaft U, which is driven by the shaft E and drives the conveyer. is driven from the shaft F by a belt and conepulleys for varying the speed.

I do not claim the feeding-coneespecially, as that has already been secured to me by a former patent; but v y g Having thus described Tiny invention, I claim as new and desire to secure by Letters Patent- The funnel B, feeding-cone C, `two or more inclined shaking sieves, G M, one or more return-chutes, L, cams I, fan K, conveyer O, and separators Q It S, all combined and arranged in a middlings-puriiier, substantially as specifled.
