SAND-DRYING DEVICE.
Application filed October 1, 1921.
To all whom it may concern:
Be it known that I, FRANK X. HEINDL, a citizen of the United States, residing at Kersey, in the county of Elk and State of Pennsylvania, have invented certain new and useful Improvements in Sand-Drying Devices,
- of which the following is a specification, reference being had to the accompanying drawm s.
This invention relates to devices for drying granular material, particularly sand, and has for its object the provision of a device by means of which sand may be taken directly from a leaching or washing apparatus and dried effectively while it passes in a continuous stream or flow over drying means.
- An important object is the provision of a device which is provided with means whereby the sand, or other material, will be caused to pass over a series of successive pans or chutes beneath which heating means is provided, the sand having its flow continuously by gravity and being discharged from the device in a thoroughly dried condition.
Another object is the provision of interchangeable burner or steam heating means for applying the necessary heat to effect dry- Still another object is the provision of a mechanism of this character which is closed so as to retain the heat therein and in which the chutes over which the sand passes are adjustable whereby to vary the angular incline thereof to insure proper feed of the material.
An additional object is the provision of a device of this character which will be simple and inexpensive in construction, easy to use, not likely to get out of order, efficient and positive in operation, durable and a general improvement in the art.
With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which:
Figure 1 is a perspective View of my device in closed position;
Figure 2 is a vertical sectional. viewtherethrough; I
Figure 3 is a detail view illustrating the adjustable mounting of the chutes;
Specification of Letters Patent.

Serial No. 504,694.
Figure 4 is a detail view of one of the heating burners;
Figure 5 is a detail perspective view of a steam heater; and
Figure 6 is a cross sectional view through the device.
Referring more particularly to the drawings, I have shown my device as comprising an upright rectangular casing 10 of sheet metal which is reinforced internally with a plurality of angle ironsupports 11 and 12, the former being vertical and the latter being transversely arranged. The exact frame construction may of course be varied as may be found advisable in actual practice so as to provide a strong structure capable of withstanding great strain. The casing 10 and frame therefor are mounted upon a suitable concrete base 13. One side ofthe casing is provided with doors 1A which may be opened to permit access to the interior for the purpose of making adjustments and repairs. The casing is also provided in one side with an inlet opening 15 and at its opposite side with a discharge opening 16. It should also be stated that the top of the casing is open. I i i J ournaled transversely of the frame at the lower portion thereof adjacent the opening 15, is a shaft 17 which carries sprockets 18 about which are trained chains 19 which extend upwardly in a'rearwar-dly inclined direction and which are trained'about sprockets 20 secured upon a shaft 21 journaled at the open top of the frame. This shaft 21 carries a drive pulley or the like 22 by means of which power may be applied for effecting movement of the chains19. Carried by the chains is a series of spaced pockets 23 designed to be filled with'sand which is shoveled or otherwise passed through the opening 15.
Located at the top of the frameis a hopper 24 into which the conveyor defined by the chains 19 and pockets23 discharges and this hopper of course has an, inclined bottom provided with an opening. It is of course to be understood that if preferred sandto be dried might be passed directly into the hopper instead of being conveyed thereto by the elevator conveyor.
Disposed within the rear portion of the frame is a series of oppositely inclined chutes 25 which may be formed of sheet chute extends to the discharge opening 16- while the upper end of the uppermost chute Y is located beneath the opening in the bottom sand dropping on tothe uppermost chute 25 of the hopper 24E.
Extending vertically through the rear portion of the device is a pipe 27 adapted to conduct either steamor gas, as the case may be. Carried bythis pipe and located beneath each chute 25 is a double burner 28 for the purpose of supplying flame against the under sides of the chutes. These burners of coursemight be of any desired type and the illustration is more 'or less conventional. v v i p y In case gas is not available or if for any reason its use is not desired, the pipe 27 may be used to conduct steam, in which event instead of the burners 28 I would make use of the steam heaters 29 which would be disposed below the chutes in place of the burners. The heaters 29 might be of varying construction though I have illustratedthem as consisting merely of a rather flat rectangular casing 30 provided at opposite corners with inlet and outlet pipes 31 and 32 and having one side formed with a series of holes 33 through which steam may issue against the chutes.
In the use of the device sand to be dried, or'in fact any other granular material, is fed directly into the hopper 24L or else is shoveled or otherwise deposited on to the lower end of-the conveyor through the opening 15. i In this latter event the sand would be carried upwardly in the pockets 23 and dumped either into the hopper 2t 'or on to the uppermost chute 25, depending uponthe specific arrangement. In either event, the
will slide therealong onto the chute next below and so onuntil the sand completes the circuit ofall the chutes and is deposited through the discharge opening 16. Owing to the inclination of the chute it is apparent that the 'feed or flow of the sand will be purely gravitational and will be insured continuously.- As thesand passes over'the successive chutes it is of course dried by the action of the gasburners or steam heaters, whichever would be used, so that when the sand is finally discharged at the bottom of the device it will be in a thoroughly dry condition either for transportation, storage or the adjusting members26 and these'adjust- Since the chutes 25 are pivotally con nected to the frame throughthe medium'of' ing members may be engaged in any desired pair of the series of openings with which they co-operate, it will be seen that by elevating or lowering a given'adjustment 26 of one of the chutes all of the chutes above this chute will have their angularity either lessened or greatened, dependent upon the direction ofv vertical adjustment of the adjusting members 26. i
From the foregoing description and a study of the drawings it will be apparent that I have thusprovided a simply con structed device by means of which sand, and in fact many other materials not susceptible to injury by great heat, may be quickly and easily dried while it is passing in a continuous stream or current and exposed to the action of heating means. It will be noted that two different feed means are provided whereby the sand may he led on to the uppermostdrying chute, the means being selectively or simultaneously variable. Itis likewise observable that owing to the adjustment which permits variation in theangula-r position of the chutes that they maybe arranged at whatever angle is found most advantageous for insuring gravitational flow of the material without danger of clogging.
While I have shown and described the preferred. embodiment of the invention, it
is of course to-be readily understood that I reserve the right tomake such changes in the form, construction and arrangement of parts as will not departfrom the spirit of the invention or the scope of the sub-joined claims. i v
Having thus described "my invention, I claim:
1'. A device of the character described] comprising an enclosed upright frame hav- 10 ing an open top, an upwardly traveling conveyorextending along the forward portion of the frame, a series of oppositely inclined chutes mounted within the 1 frame and pivotally connected therewith at their upper ends and discharging intoone another, the free ends of the chutes bearing upon the chute next below adjacent the pivoted end chute next below adjacent the pivoted end thereof, and heating means beneathl each chute," the pivotal connection of the upper ends .of the chutes with the framebeing ad- 'justab-le.
3. A 'device of the character described comprising an enclosed upright frame having an open top, an upwardly traveling conveyor extending along the forward portion of the frame, a series of oppositely inclined chutes mounted within the frame and pivotally connected therewith at their upper ends and discharging into one another, the free ends of the chutes bearing upon the chute next below adjacent the pivoted end thereof, heating means beneath each chute, and 10 means for independently vertically adjusting the pivotal connection of said chutes with said frame.
In testimony whereof I hereunto aflix my signature.
FRANK X. HEINDL.
