a suitable cooling medium.
UNITED STATES Patented December 15,1903.
PATENT OFFICE.
CHARLES WALDREN STANTON, OF MOBILE, ALABAMA.
APPARATUS FOR DRYING EARTHY SUBSTANCES.
SPECIFICATION forming part of Letters Patent No. 746,892, dated December 15, 1903.
Application filed October 10, 1902.
To all whom it may concern:
Be it known that 1, CHARLES WALDREN STANTON, a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, haveinvented new and useful Improvements in Apparatus for Drying Earthy Substances, of which the following is a specification.
This invention relates to certain new and useful improvements in apparatus for drying earthy substances; and it consists of the novel combination and arrangement of parts hereinafter more specifically described, and illustrated in the accompanying drawings, in which- I Figure l is a vertical sectional elevation of my improved apparatus, and Fig. 2 isa front elevation thereof.
Referring to the drawings by referencenumerals, 1 denotes a furnace provided with the grate-bars 2, supported upon the lugs 3, and, further, provided with an opening 4 to permit of access to the fire-box 5 and an opening 6 to permit of access to the ash-pit. The opening a is provided with the doors 7, and the opening 6 is provided with the door 8.
The reference-numeral 9 denotes atank or receptacle which is provided with an accessopening closed by means of the hermeticallysealable door 10. The top of the tank or receptacle 9 has communicating therewith a take-off pipe 11. The end of the take-off pipe 11 which communicates with the tank 9 is hermetically connected thereto, as at 12. The free end of the take-0E pipe 11 terminates in a worm 7*, arranged in areceptacle 7, forming a condensing-chambelyin which is placed The'end of the worm 7 projects from the receptacle 7 and terminates in a pipe 7? for the discharge of the products of condensation into a suitable receptacle 18, forming a reservoir and in whichis arranged a liquid seal 1%. The seal 14 in the receptacle prevents any back pressure of air to the tank and, further, prevents theescape to the atmosphere of any of the uncondensed products. The reservoir 13 is provided with a discharge-cock 15 for the products of condensation and discharge-cock 16 for the uncondensed products. The latter may be discharged in the atmosphere, if it be so desired, or carried to any suitable point and used for any suitable purpose.
berial No. 126,779 (No model.)
The receptacle '7' and the receptacle 13 are provided with suitable inlet and outlet cocks 7 and 7 respectively.
The operation of the apparatus is that the material is placed within the tank or receptacle 9 and the same hermetically sealed. The material is then subjected to a slow heat, and the vapors arising therefrom pass off through the pipe 11 into the condensing apparatus, where they are condensed,and then discharge into the reservoir 13 through the pipe 7 The products of condensation are discharged from the reservoir through the cock 15. The uncondensed products are discharged from the reservoir through the cooks 16 It is thought the many advantages of drying materials in a hermetically-sealed vesselin the manner set forth can be readily understood from the foregoing description,taken in connection with the accompanying drawings.
Having thus fully described my invention, what'I claim as new, and desire to secure by Letters Patent, is- V In an apparatus for drying earthy substances, a furnace, a hermetically-sealed tank mounted thereon and having a semispherical top, a take-off pipe connected at one end to the top of said tank and communicating with the interior thereof, a condensing-worm having its upper'end communicating with the other end of said take-off pipe, a reservoir, adapted to contain a liquid to form a permanent seal, a discharge-cock connected to one side of said reservoir near the top thereof, a discharge-cock connected to the top of said reservoir, a suitable inlet and outlet connectedto the top and side, respectively, of said reservoir, and a discharge-pipe communicating at its top with the lower end of said condensing-Worm, and at its lower end extending through the side of and into said reservoir near the bottom thereof and projecting .into the liquid seal contained in said reser- CHARLES WALDREN STANTON.
