UNITED STATES PATENT OFFICE.
4DAVID l?. GLEVELAND, 0F DALLAS, TEXAS, ASSIGNOR T0 UNIVERSAL PAINT REMOVER AND MOTOR CLEANING COMPANY, OF DALLAS, TEXAS.
HEATING APPARATUS.
To'll whom t may concern.'
Be it known that I, DAVID P. CLEVELAND, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification.
My invention relates to apparatus for heating and drying a finely divided abrasive material, such as fine damp sand, in order that it may be fed through a pipe or hose.
An important object of the invention is to provide apparatus of the above mentioned character, which is simple in construction, and reliable and automatic in operation.
In accordance with my invention, I provide a furnace or heating member, to which is preferably secured a receptacle for heating the damp sand to be heated and dried. A follower is arranged to engage with the top of the mass of sand, and has a suction pipe connected therewith, through which the dried sand is drawn.
In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,
Figure l is a side elevation of apparatus embodying my invention, parts being shown in section,
Fig. 2 is a plan view of the same,
Fig. 3 is a plan view of the follower, and,
Fig. 4 is an end elevation of the same.
In the drawings, the numeral 5 designates a vertical cylindrical shell of a furnace or heating unit, of any well known or preferred construction, and utilizing any suitable form of fuel.
The numeral 6 designates a drying casing or chamber, which is circular in horizontal cross section and secured to the outer surface of the shell 5, at its ends, as shown at 7 The casing 6 forms with the shell 5 the drying chamber, the shell 5 constituting the 1nner wall thereof. 'This drying chamber 1s preferably disposed at the rear side of the shell 5, and extends about the same in concentric relation.
The numeral 7 designates la vertically movable follower, which is longitudinally curved to properly t within the drying chamber. This follower is suitably heavy and engages the top of the mass 8 of the damp line sand,

and moves downwardly by gravity as the sand is withdrawnin the dried condition.
The follower 7 is provided at a point equidistantly spaced from its opposite ends with an opening 8 assing through its upper and lower faces. his opening receives one end of the goose neck or U-tube 9, which is rigidly held therein. The opposite end of this goose neck has a guide block 10, rigidl secured thereto, and slidably contacting wit the outer surface of the casing 6. The lower end of the outer arm of the goose neck 9, beneath the guide block 10 has connection with a flexible suction pipe or hose ll, through which the dried sand is drawn by suction, the hose 11 being connected with an injector nozzle or other suitable device.
In operation, the furnace 5 or heating element is operated for a suitable length of time to thoroughly dry the sand, within the drying chamber. This having been done, suction is supplied to the hose 11, and the dried sand directly beneath the intake end of the goose neck 9 will be drawn into and through this goose neck. The sand being fine and thoroughly dried will readily cave to fill the crater formed beneath the intake end of the goose neck, this action being aided by the weight of the follower 7. Furthermore, the upper portion of the sand which will dry the quickest and more thoroughly is removed first, aiding in the drying of the lower portion of the sand, before it is reached. The dried sand passing through the neck 9 is conveyed through the hose 11, to the point of use, which may be into a steam injector nozzle, where it is combined with a liquid chemical employed in removing paint from a painted surface.
It is to be understood that the form of my invention herewith shown and described is to be taken as a perferred example of the same, and that various changes in the shape, size'and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claims.
Having thus described my invention, I claim:
1. In apparatus of the character described, the shell of a heating element, a dryin chamber arranged in proximit to the she 105 for the reception of damp san to be dried,
a follower arranged upon the top of the mess of sand to move downwardly therein, and a suction pipe [connected with the follower and leading into the drying chamber beneath the follower.
2. ln apparatus of the character described, the shell of e heating element, e drying ehuinber secured thereto, il vertically movable follower operating within the drying chamber. u goose neck eonneeted with the follower' and lending into the dr in'r ehember beneath the follower, and a exixble eonduit eonneeted with the opposite end of the goose neck.
3. In apparatus of the character described,
a heating shell, e drying chamber eqrried thereby and vertically arranged, e follower operating within the drying vhzunber and having un opening formed therein passing through the upper und lower surfaces of the seme, a goose neek having one end severed within the opening, a guide block secured to the outer erm of the goose neel( near its lower end :rnd slidzibly engaging the exterior of the drying (chamber2 und :L flexible Suction conduit seeilred to the outer erin of the goose neek beneath the guide block.
1n testimony whereof I aHiX my signature.
DAVID P. CLEVELAND.
