SAND DRIER.

UNITED STATES JOHN G. MCPHERSON, OF MATTOON, ILLINOIS.
SAND-DRIER.
SPECIFICATION forming part of Letters Patent No. 276,445, dated April 24, 1883,
Application filed December 20, 1882. No model.)
i To all whom it may concern her, the drier being adapted to receive the sand to be dried at the top and to' discharge it at the bottom.
The invention also consists of the particular construction, combination, and arrangement of the parts of the drier, all as hereinafter described and claimed. Reference is tobe had to the accompanying drawings, forming part of this specification, in which similarletters of reference indicate corresponding parts in both the figures.
Figure l is a central sectional elevation of my invention, and Fig. 2 is a sectional plan view taken on the line m m of Fig. 1.
A represents a fire-chamber. B B represent a series of circularlyarranged pipes or fines, and B a central flue. These flues lead from the chamber A up to the chamber 0, formed by the dome-shaped cover D, placed over the top of the flues, as shown in Fig.1; and E represents the outer wall, which surrounds the fire-chamber and the said flnes, and forms the space F around the fire-chamber and the space F above the fire-chamber, (around and between the flues,) which spaces form the drying-chamber for the sand. In the center of the dome-shaped cover D is formed the opening 01, through which the products of combustion from the fire-chamber. pass. Below the fire-chamber is formed the ash-pit G, which receives the ashes from the fire-chamber. The top of the surrounding wall E is provided with the hopper H, which facilitates the shoveling of the sand to be dried into the drying-chambers. At the bottom of the spaceF are formed the outlet-passages f f for the sand after it has become thoroughly dried. While the sand is being dried these outlet-passages are closed by the sliding plates 1) b, as clearly indicated in the drawings.
J represents the opening through which the fuel is placed in the firechamber, whichopening is closed by the door K. i I
The drieris by preference made circular in Form and of cast-iron.
The fire-chamber is cast as a separate part,
the pipes B are held in place by the circular plate N, which is formed with as many openings n as there are pipes B, and with a centralopening, n, for the passage of the upper end of the central pipe, B, and this plate N is formed upon its under side with the circular flanges m to retain the upper ends of the pipes, and the outer edge ot the plate is formed with the upwardly-projecting circumferential flange o for retaining the cover D, which fits within the said flange 0, as shown in Fig. l.
The ash-box G is a separate casting, and it supports the whole structure upon the annular plate N, placed thereon, which plate is larger than the ash-box, and is formed with the discharge-openingsff, above mentioned, and is formed upon its under side with the ribs (1 d, which are undercut, and form the ways in which the plates 1) b, which open and close the dischargeopenings f, slide. Upon this annular plate N, inside of the fire-chamber, are placed the gratebars L, which are held in place by the rib Z, and the outer edge of the plate is formed with the upwardly-projecting flange l, which holds the outer wall, E, in place upon the plate, as shown in Fig. 1. The outer wall, E, is by preference formed of the cast sections h h, which are provided at their upper edges with the flanges z i, which form seats for the sections above to rest in, and for the hopper H at the top of the wall.
Thecentralpipeor flue,B, passes up through the plate N, as shown in Fig. 1, so that the expansion of this pipe, when heated, will not lift the said plate off from the ends of the circular series of pipes B, and this plate N is formed with the small holes f f for the escape of the moisture which rises from the sand in the drying-chamber.
In use the sand to be dried is shoveled into the hopper H, from whence it falls into and fills the space F, surrounding the fire-chamber, and also the space F, above the fire-chamber, filling it around the pipes and upon the cone L. After the sand has become thoroughly dry from the heat from the tire-chamber the slides 12 b are to be withdrawn for opening the passagesf, which permits the sand to flow out of the chambers, the cone L causing the sand to be discharged from the chamber F into the space F, and from thence out through the openings f.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a sand-drier, the combination, with the fire-chamber A, having the conical top L, the pipes B B, and the plate N, provided with the apertures 12 n, of the cover D, having central opening, d; and the wall El, surrounding the said chamber and pipes, and providedwith the hopper H, substantially as herein shown and with the hopper H, substantially as herein shown and described.
3. In a sand-drier, the combination, with the fire-box A, having conical top L, of the pipes B B the plate N, provided with the apertures 1 not to receive the said pipes, and the ventapertnresf,substantially as herein shown and described.
