JAMES II. MONTGOMERY, OF DENVER, COLORADO.
PULSATING WATER-SEPARATOR FOR REMOVING ROCK, GRIT, 0R FORElGN MATTER FROM GRAIN.
SPECIFICATION forming part of Letters Patent No. 533,821, dated February 5 1895.
Application filed May 4, 1894. Serial N01 510,066. (No model.)
To all whom it may concern.-
Be it known that I, J AMES H. MONTGOMERY, acitizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, haveinvented a certain new and useful Pulsating WaterSeparator for Removing Rock, Grit, or Foreign Matter from Grain; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, and to the letters of reference marked thereon.
Figure 1, of the drawings represents a vertical longitudinal section on the line y-y, Fig. 2. Fig. 2 represents a cross-section on line ar--a:, Fig. 1.
The object of this invention is to provide means for separating from grain, and especially from wheat, by water pulsations, such particles of rock, chaff, and other foreign matter, as may be left intermingled therewith, after the grain has been acted upon by thrashing or cleaning machines of ordinary character. It is designed to thoroughly separate all grit from the grain so that it may be fed to reducing machines of exact and fine construction without danger of injuring the same.
In the accompanying drawings the letter A, designates a water-tight box or tank, and B, an inclined screen or sieve extending longitudinally in the upper portion of said tank, and suspended or supported therein, so that it is just submerged below the surface of the water with which the tank is designed to be nearly filled. The screen has a small mesh to retain the grains of wheat while allowing the smaller particles of grit to pass through into the lower portion of the tank. The tail 0 of the screen is sufficiently raised above the wire cloth bottom to dam up the grain to the depth of an inch or more, said grain being designed as the screen fills, to flow over the tail board into the chute in the end of the tank, whence it is discharged through a valve spout D.
An up and down reciprocating motion is given to the screen by means of small rotating cams a, on a shaft 79, said cams being connected to the screen by suitable arms, 0. This reciprocation produces upon the Wheat grains in the screen a pulsating action causing them torise, loosen from each other and fall back at each pulsation. Ihe particles of rock and grit being specifically heavier than the grains of wheat, are by these pulsating motions, gradually washed down through the grain to the bottom of the screen, which allows the finer grit to pass through its mesh but retains the larger particles. These larger pieces of rock and grit accumulate at the lower end of the screen being gradually shaken into a receptacle or pocket cl, preferably at the side from which they may be taken, when there is a sufficient quantity. In order to cause a lateral movement of these larger particles of grit aslight lateral inclination may be given to the bottom of the screen.
The grain is fed into the hopper E, whence it passes by the hopper spout g, to the screen. lVhilegood thrashed grain will sink in water, some of the berries may require a little soaking, and in order to prevent these from i-ioating along the surface of the water past the screen with the chaff, a canvas or other drag G is provided across the head portion of the screen to exert a submerging action on the berries, holding them until they are soaked sufficiently to sink. This drag extends transversely of the tank, its ends being'connected to the sides thereof.
' In order to let the water and sediment out of the tank, a discharge spout I is provided at its bottom portion.
The level of water is preserved by the surface spout J. If running water is employed, being supplied to the tank by a pipe K, the chaff and light stuff will float along the surface of the water, and be discharged through the spout J. A screen Z, just below the water surface, extends to the discharge end of the tank to prevent chaff covered grain from soaking and falling into the chute with the good grain.
I am aware that there are several ways of producing a pulsating efiect of the water on the grain therein, and I do not therefore'desire to be confined to the mechanism hereinbefore described for this purpose.
Having described this invention, what I claim, and desire to secure by Letters Patent, 1s
