COAL-STORAGE PLANT.

SPECIFICATION forming part of Letters Patent No. 772,911, dated October 25, 1904.

Application filed July 20, 1903. Renewed July 29, 190 i. Serial No. 218,610. (No model.) I

To all whom, it may concern:

Be it known that I, ALFRED M. AOKLIN, a

resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have in vented a new and useful Improvement in Coal- Storage Plants; and I do hereby declare the following to be a full, clear, and exact description thereof. I

My invention relates to a coal or like storage plant, its object being to provide for the storing of coal in large quantities and to provide a simple form of. apparatus for the removal of same for loading in the cars or other receptacles.

Referringto the accompanying drawings, Figure 1 is a sectional view of a suitable storage tank or bin, showing the apparatus therein for the removal of the coal and the loading of same into a car. Fig. 2 is a plan view of the apparatus, the tank or bin being shown in section. Fig. 8 is an enlarged plan'view of the vertically and horizontally movable frame, partly brokenaway. Fig. 4 is aside View of same. Fig. 5 is an enlarged, section on the line 5 5, Fig. 1. Fig. 6 is a vertical section of the portionof the hollow pillar or support and the surrounding sleeve. Fig. -7 is a detail view of door and'lift mechanism. Fig. 8 is an enlarged view of the scraper-carriage removed, and. Fig. 9 is a view of a plant embodying three bins or tanks' connected up by the same conveying mechanism for carrying the coal or like material to the car.

Like numerals indicate like parts in each 0 the figures.

In the drawings the numeral 2 designates a suitable foundation for a bin or tank 8, said made toslope from the center and from-the sides toward the grating, so that all water contained within the coal will be drained toward the grating 5 and carried off by the channels 6 and 7 to a suitable outlet. Formed within, the floor lis the outlet 8, arranged, preferably, at or near the center of the bin, said outlet being formed with sloping sides, and beneath said outlet 8 is the tunnel 9, within which travels the endless belt or conveyer 10,

said belt or conveyer being mounted on suitable driving-pulleys 11, at each end thereof, and supported at intermediate points by the pulleys 12. receivethe' material passing through the outi let ,8 and conveys the same to the vertical con- I veyer or elevator 13, which lifts the coal and deposits it by the chute 14 into thecar 15. As any suitable conveying apparatus may be employed and it forms no part of my invention, I have not deemed it necessary to illustrate the same in full.

Located over the opening 8 within the tank or bin 3 is the hollow pillar or support 16,

which may form the central support for theroof 4 and which extends up beyond said roof and is provided at the top with the cap 17 The pillar 16 is provided with sliding doors 18, said doors being arranged around said pillar, as shown, at suitable intervals, the

plates 19 forming guides for said doors. Three sets of these doors are illustrated, one above the other, and it is apparent that more may be employed, if found desirable. To provide for the raising of said door, each of said doors is provided with the vertical rack-bar 18?, with which the pawl 18 engages. A le-i The conveyor 10 is adapted to ver 18, pivoted at 18, has its inner end engag- 5 equalizing-bar 24, as shown in dotted lines.

A motor 20 is mounted on a suitable-support, the motor-shaft being geared up to the shaft 20 This shaft 20 has the sprockets 20,

connected up by chains 2t to the sprocketwheels on the shafts 21. By this construction the sleeve 20 may be quickly raised or lowered.

The sleeve20 is a non-rotary sleeve and is held from rotation by means of the vertical strips 25 on the outer face of the pillar 16, which engage with the lugs 26 on the inner walls of the sleeve 20. Vithin the lugs 26 are journaled the friction rollers 27, which bear against the vertical strips 25 on the pillar 16, whereby the sleeve 20 is free to move up and down on said pillar, but is prevented from rotating around same.

Secured to the sleeve 20 is the circular track 28,upon which the wheels 29 travel,said wheels being mounted on the frame 30. The frame 30 is adapted to swing or rotate on the sleeve 20, and to provide mechanism for this action the sleeve 20 is provided with the circular worm-rack 31, with which the worm 32 on the shaft 33 is adapted to engage. This shaft 33 has the gear-wheel 34, meshing with the pinion 35 on the shaft 36. This shaft 36 has the gear-wheel 37, meshing with the pinion 38 on the motor-shaft 39 of a suitable motor 40, supported upon the frame 30. By supplying power to the motor it is apparent that through the connections described arotary motion will be imparted to the frame 30, the wheels 29 thereof traveling around the track 28 on the sleeve 20. The frame 30 projects out toward the walls of the bin to a suitable point, and mounted at the outer end of this projecting portion 41 is the pulley 42, around which the endless cable 43 passes, said cable also passing around the pulley 44 on said frame. A suitable motor 45 is mounted on the opposite end of the frame 41 for driving the endless cable 43. A belt 45 connects the motor 45 with the shaft 44. The motor 45 is preferably mounted on the weight 45 so that said motor assists said weightin balancing said frame 30. The outwardly-projecting portion 41 of the frame 30 is provided with the track 46, upon which the scraper carriage 47 is adapted to travel, said carriage having the Wheels 48 engaging the upper faces of the rails of said track and the wheels 49 engaging the lower faces of the rails. A hinged or swinging scraper 50 is mounted on the scraper-carriage 47, said scraper being hinged at 51 and being held against backward movement by bearing against the scraper-carriage. As the scraper-carriage moves toward the center of the bin the scraper will be in position to scrape the material toward the center of the bin, but on its return will be free to swing so as to pass over any impediments in its path.

W hen my improved storage plant is in use, where a bin is used the bin 2 will be filled with coal or other material to a considerable height therein. WVhen it is desired to remove any of the coal from the bin, one of the doors 18 will be raised and the coal adjacent thereto will fall through said opening until the coal takes substantially the position indicated in dotted lines, Fig. 1. The motor 45 is put in operation to drive the cable 3, whereupon the scraper-carriage 47, which is secured to the cable 43, will travel toward the center of the bin and the scraper 50 being in proper position with reference to the top of the coal will act to scrape or carry a portion of the coal from the top toward the center of the bin, where it will descend by its own gravity down through the opening 18 into the hollow pillar 16, whence it passes by the outlet 8 onto the conveycr 10 to be carried to the conveyor or elevator 13 and thence by the chute 14 to the car 15. In order to scrape the coal evenly from the top of the pile. the frame 30 is shifted so as to scrape the coal from different points, and accordingly power is transmitted through the motor 40 to the worm-slutft 33, whereby the worm 32 meshing with the worn'i-rack 31 causes the frame 30 to swing around, and when brought to the proper position the motor 40 is stopped and the motor 45 started up, whereupon the scraper will advance toward the center of the bin and scrape the coal from that section of the bin toward the center. Meanwhile the door 18 in radial line with the position of the frame 41 is opened, so that the coal scraped from that section will pass through the door into the hollow pillar It, to be conveyed by the conveyer 10 in the manner above set forth. \Vhen the scraper has scraped off the upper layer of the coal all around the bin, it will be necessary to lower said scraper in order to bring it into operative position, and for this purpose the sleeve 20 is lowered, carrying with it the frame 30. In order to lower the sleeve 21), power is applied to the motor 20, whereupon said sleeve will be lowered, the side rollers 27 thereof traveling on the vertical strips 25 of the pillar 16. \Vhcn the sleeve has been lowered to the proper distance, the power is shut oil from the motor 20 and the frame 30 may then be swung mto proper position and the scraper operated as above set forth. The lowering of the sleeve 20 may make it neeessary to use the next lower set or row of doors 18, and these doors are opened in order, aecording to the direction of the projecting frame 41. .In this manner the coal may be scraped evenly from the top of the pile and discharged from the bin in regular quantities. Any water or moisture contained in the coal will be allowed to settle to the bottom of the tank and pass off through the grate 5, so that the coal contained within the tank is thoroughly drained and is dry and the more easily handled.

In Fig. 9 l haveillustratcd a series of tanks arranged side by side and connected up by a single conveying device, so that any one or more of the tanks may be put in operation and the coal conveyed to the loauling-point.

By thisconstruction differentgrades of coal can be kept in different tanks, and bythe use of the above described apparatus the coal from any one tank may be discharged onto the conveyer and loaded on the cars.

It is'obvious that my invention may be employed without the use of abin or. where the coal is'simply arrangedin piles.
