UNITED STATES PATENT OFFICEe ERNST AUGUST WEINHOLD, OE LOUVAIN, BELGIUM.

APPARATUS FOR WASHING AND CLEANSING GRAIN.

SPECIFICATION forming part of Letters Patent No. 562,053, dated June 16, 1896.

Application iiled May 4,1895. Serial No.548,155. (No model.) Patented in Belgium October 20, 1894, No.112,324; in France October 23, 1894, No. 242,317; in Italy November 7, 1894,No. 37,546, and in England November 19, 1894,1To. 22,329.

To all whom it may concern/.-

Be it known that I, ERNST AUGUST VVEINJ HOLD, a subject of the King of Prussia, German Emperor, and a resident of Louvain, in the Kingdom of Belgium, have invented an Improved Apparatus for Vashing and Cleansing Grain and the Like, (for which I have obtained patentsin GreatBritain, No. 22,329, dated November 19, 1894; in Belgium, No. 112,394, dated October 20, 1894; in France, No. 942,817, dated'October 23, 1894, and in Italy, No. 37,546, dated November 7, 1894,) of which the following is an exact specification.

This invention relates to an apparatus by moans of which the grain or similar material may be washed as well as freed from all those parts the specific gravity of which is other.

wise-2'.. e., higher or lower-than that of the I obtain the desired result by exposing the grain to the action of slowly-flowing water, the velocity of which is such that those particles which are too heavy cannot be moved away by the water. The other particles-2'. c. ,those of the right weight as well as those of too low a weightare moved away by the water and are transported into a vessel, within which a separation takes place, in that the sound grain sinks down upon an inclined bottom, while the other grain is led over into another compartment for undergoing another separation.

In order to make my invention more clear,

I refer to the accompanyingdrawings,in which similar letters denote similar parts throughout the diffrent views, and in which- Figure 1 is a vertical longitudinal section through the apparatus. Fig. 2 is a vertical cross-section through the same, and Fig. 3 is a horizontal section taken on line 4 5 of Fig. 1.- Referring to the accompanying drawings, a designates a frame holding a vat b, the bottom of which is sloping. Said bottom supports a -funnel-like vessel c, the lower opening of which is closed by a lever d d', fulcrumed at d3 to a bracket e. The arm d of said lever is Jfurnished with a weight d2, by means of which a piece of rubber, leather, or the like attached to arm d is pressed upon the opening of funnel c. Within the upper opening of said funnel is arranged a circular trough f, consisting of an outer inclined wall and an inner vertical wall. The latter carries a hollow casting /,having the shape of a truncated cone. The small top plate of the latter is provided with a vertical rod h, carrying by means `of its upper end a hopper t', the lower cylindrical portion of which is screw-threaded and is encompassed by a short piece of tube 7c. The latter carries an inverted hopper l, taking over the cone g aforementioned. The intermediate space between the parts g and l, may

be decreased or increased by screwing the piece of tube 7,; down or up along the threaded end portion of hopper Hopper 'i is the feed-hopper of the apparatus. The grain passing from 'L' to l is uniformly distributed over and by the cone g and glides down into the circular troughj'. The latter communicates throughout its whole circumference with the funnel c.

Funnel c is kept filled with water by means of the pipe n. The water enters the trough f through the annular slot in the bottom of the latter and flows in a uniform stream in an upward direction through said trough. The feed of the water is chosen so that the velocity of the water within the trough is such that those particles of grain having too great a specific gravity cannot be transported by the moving water-4'. c., cannot be caused to flow, together with the water, over into the vat b. The said particles fall down into the funnel c, in the lower portion of which they collect.

From time to time the lever-arm CZ is raised, so as to free the lower opening of the funnel from arm d and allow the particles collected to leave the funnel.

The speciiic gravity of the sound grain washed into the vat b by the water flowing out of the trough f is a little higher than that of the water, and said grain will therefore sink down upon the sloping bottom of the vat and will escape out of the same through the gutter o, together with as much water as allowed by the position of the adj ust-able slidevalve p. The latter may be operated by the rod q, and is in any case adjusted so that the quantity of water flowing out of the funnel through said gutter 0 is somewhat less than that of the water entering the funnel through IOO The excess of the water iows through two nozzles o' into a Vsecond` vat s, the bottom of which is likewise sloping. Said second vat is connected with gutter 0 by a gutter t, which also may be opened or closed by a slidevalve it, operated by a rod fu. The water iiowing into vat s takes withit that grain which has been swimming upon the surface of the water contained within vat b. That part of this grain which is tolerably sound will slowly sink down upon the sloping bottom of vat s and will flow away through the gutter z5 into the gutter 0. The remaining part of the grain is unsound and will iiow on?, together with the excess of water, through the waste-pipe w. The slide-valve u is adjusted in such a way that the height of the water within vat s is kept on a level with the wastepipe w. The sound grain contained in vat s is prevented from flowing away through pipe w by means of two cross-plates 03 ad.

. Having thus fully described the nature of niy invention,' what I desire t0 secure'by Letters Patent ofthe United States is InY an apparatus for washing and cleansing grain and the like, the combination with a conical body arranged upon said vertical wall,

and adapted to distribute the grain uniformly upon the surface of the water within the said trough; a hopper leading the grain onto the top of said conical body; another basin encircling the iirst-n1entioncd basin, and having an inclined bottom, and a valve at the lowest part of said bottoni; and a watersup ply pipe terminating below the said conical body in said first-mentioned basin, substantially andfor the purpose as described.

In testimony whereof I have signed this speciiication inthe presence of two subscribing witnesses.
