UNITE STATES PATENT OFFICE.
ROBERT C. HAlVLEY AND GEORGE E. HAVLEY, OF SOUTH BEND, INDIANA.
APPARATUS FOR HEATING GRAIN.
SPECIFICATION forming part of Letters Patent No. 394,267, dated December 11, 1888.
Application filed March 16, 1888. Serial No; 267,4;10. (Model-l To all whom it may concern.-
ie it known that we, BoBERT C. HAWLEY and GEORGE E. llA\VLEY, citizens of the United States, residing at South Bend, in the county of Joseph and State of Indiana,
have invented a new and useful Improvement in Apparatus for Heating Grain, of which the following is a specification.
Our invention relates to an improvement IO in apparatus for heating grain preparatory to grinding the same in mills; and it consists in the peculiar construction and arrangement of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claim.
The accompanying drawing is partlya vertical sectional view and partly an elevation of the grain-heating apparatus embodying our improvement.
A represents a heater or furnace through which extends a coil of pipe, 15. From the upper end of the said coil, the said pipe extends in a vertical direction, as at (l, and is provided at its upper end with a' cylinder, D. Communicating with the upper end of said cylinder and coiled around the same is a pipe, .1, the lower end of which pipe communicates'with'the lower end of the coil B, and thereby forms a complete circuit through which water may circulate.
F represents areservoir, which is provided at its lower end with a pipe, G, that communicates with the pipe E.
H represents an outer shell or drum, which envelopes the cylinder 1) and the coiled por tion of pipe E, and is of greater diameter than the said coil, whereby a snliicient space is left between the outer shell and the coiled portion of the pipe E for the passage of grain. The upper and lower ends of the said outer case or drum are conical in shape, as shown, and the upper and lower ends of the cylinder 1) are also conical in shape.
The interior diameter of the coiled portion 45 of pipe E is greater than the exterior diameter of the cylinder D, and the interior diameter of the casing H is greater than the exterior diameter of the coil, and thereby space is left between said cylinder D and the coil and between the latter and the casing.
The upper and lower ends of the drum or case II are provided with openings I K, respectively, the latter being provided with a suitable cut-oif valve, L.
The operation of our-invention is as follows: The valve L is closed, and the grain to be heated is poured into the drum or case H, and is thereby caused to surround the cylinder D and the coil of pipe E around said cylinder. A suitable quantity of water is supplied to the pipe E from the reservoir, and as the water flows through the coil B it becomes heated by the tire in the furnace, and is forced upward into and through the cylinder D, and from the same through the surrouliiding coil E, thereby maintaining the hotwater in constant circulation, and consequently heating the coil E and the cylinder D, and thereby thoroughly heating the grain inclosed in the case or drum H around said cylinder and coil. hen the grain is sufliciently heated, the valve L is opened and the grain is discharged from the drum through the opening K.
Having thus described our invention, we claim The combination, in a grain-heater, of the vertical cylinder D, having the conical upper and lower ends to facilitate the passage of grain around said cylinder, the pipe E, communicating with the upper end of the cylinder and coiled around the same, the pipe 0, extendin from the lower end of the cylinder, the outer shell enveloping the cylinder and coil and having its upper and lower ends coneshaped, and the valve in the lower end of the shell, substantially as described.
In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
