OF NEW YORK, N. Y.
SPECIFICATION forming part of Letters Patent N 0. 690,082, dated December 31, 1901. Application filed December s, 1909. strain). 38,492- (Nomodel- To to whom it may concern.-
Be it known that I, GEORGE D. SNYDER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Clay-Separating Apparatus, of which the following is a specification.
This invention relates to means comprising an improved apparatus for the treatment of kaolin or china-clay and the like, the same being intended to wash out the clay and free it from sand, mica, and grit bya continuous, expeditious, and efficient process.
In order that my invention may be properly understood and explained in detail, I have annexed heretoasheet of dra\vings,wherein Figure 1 is a sectional elevation of the complete apparatus. Fig. 2 is an enlarged detail View of a beater or disintegrator. Fig. 3 is an end View of Fig. 2, and Figs. etand 5 are de tail views showing the pear-shaped openings in the blades.
In the drawings the letter A indicates a circular receptacle wherein the clay is beaten with water, broken up, and formed into a creamy mass,the clay beingprimarily dumped into an adjacent hopperB, from the bottom of which a chute 1) leads into the lower portion of receptacle A. I preferably provide a spiral conveyer 1) within chute Z) to facilitate the downward passage of the clay, said spiral couveyerbein g rotated by power. W'ater is introduced through the same channel together with the clay, the supplythereof being suitably regulated.
0 indicates a vertical shaft located within receptacle A and extending to near the base thereof. The said shaft is provided with a bevel-gear c at its upper end,where it is rotatably supported in bearings formed in a crosshead 0, and a corresponding bearing is provided in a transverse bar 0 arranged near the lower end of the shaft. A drive-shaft D, "communicating with a source of power, (not shown,) is mounted in bearings l, which are supported upon the cross-head c, and termi- Dates in a bevel-gear 0 which latter meshes with the gear a, as seen. v
Secured upon the shaft 0 and adapted to rotate therewith are a series of circularlyacting paddles or heaters E, arranged at suitable intervals apart to render efficient service.
The construction of these paddles or beaters is more clearly shown in the enlarged views of Figs. 2 and 3. As seen, each composed of the oppositely extending blades e e, the set of said blades having opposite inclinations, and said blades having approximately pear shaped angular apertures e therein to throw the center and upwardly withoutbreaking up the sand particles. The rotation of the inclined paddles or heaters breaks up the clay, mixes the water withit until in the form of a creamy the upper portion of the receptacle A. The elevated mass of clay and water passes off through an elongated spout a, falling into a vessel F, arranged to receive it. As this vessel fills the heavier foreign particles natu- 7o rally remain at the bottom and the clayey mass again passes otf through an elongated spout f, falling thence into a second vessel G, which latter has an elongated overflow-spout g, permitting the mass to fall smoothly into 75 a trough H. The spouts a, f, positing the fluid mass gently at low points in the respective vent disturbance of the body therein, and thus cles to settle and remain undisturbed at the bottom thereof. Said trough H is of considerable length and may be arranged in a suitable manner to economize space. It is and g by deand smoothly receivers preof the mass necessary for the fluid clay to traverse a cer- 85 tain length of trough in the process of eliminating the impurities, although such length is greatly diminished by the use of my appa ratus, and to aid the operation I place rifiles, as H, to collect the sand, and the mica, which latter element it is ordinarily a difficult matter to remove from kaolin. My rifiies are boards pivoted or hinged at their upper ends to the sides of the trough, as seen at h, whereby they may be raised to flush the 95 trough in cleaning it out, stops 7L2 being provided to hold the riffles in operative position. Alternating the ritl'les H along the trough course are the bridges 7L ,-Wl1l(3l1 extend downwardly to a point below the upperends of the ICC rifiies, said bridges being provided with the horizontally-extending platforms 71 To operate the riflles H, I provide extensions 7L5 therefor and connect same pivotally with a paddle is the broken-up mass toward fluid mass, and elevates said mass to permit the heavier partiparticularly 9o common horizontal bar 2, said bar itself being pivotally connected to an operating-lever i, which latter is fulcrumed at 11 By the operation of lever 71 the riffles H may all be simultaneously elevated or lowered, as desired. It will be understood that the liquid mass passing rapidly alongthe trough after surmounting a riffie in its path impinges against a bridge 72, and the under side of its extension h, and the impact and depressing effect causes the heavier particles, such as the mica and grit, to descend to the bottom of the trough, where they are caught and held by the next riffie met with. The claywater runs into filter-presses and is subsequently dried out in the usual manner.
A indicates a manhole in the receptacle A for cleaning out the latter and having a suitable cover A A indicates a valved nozzle arranged near the bottom of receptacle A and intended for service in drawing off the fluid mass when the apparatus has stopped working.
Having now described my invention, I declare that what I claim is- 1. In a clay-separating apparatus, in combination, a beating-engine, and a trough leading from said beating-engine in the path of the beaten product, said trough having a series of pivoted riffles, stops therefor, and a series of impact-bridges alternating therewith; together with a connector between said riffles, and a lever whereby said rifides may be simultaneously raised or lowered.
2. In a clay-separating apparatus, in combination, a beating-engine consisting of a cylinder having a feed-opening near its base, a vertical shaft rotat'ably supported in said cylinder, a series of heaters or paddles carried by said shaft, means for rotating the latter, and an overflow-spout for said cylinder; the said boaters or paddles being set in horizontal pairs at opposite inclinations, and each beater or paddle having a series of approximately pear-shaped angular apertures therein arranged to throw the beaten mass upwardly toward the center of the cylinder without breaking up the particles.
In testimonywhereof I have hereunto set my hand in the presence of two subscribing witnesses.
