UNITED STATES PATENT OF IC PEETE B. CLARKE, OF BIRMINGHAM, ALABAMA.

APPARATUS FOR HANDLING COAL IN BULK.

SPECIFICATION forming part of Letters Patent No. 512,680, dated January 16, 1894. Application filed February 23, 1893. Serial No. 463,387. (No model.)

To all whom it may concern.-

Be it known that I, PEETE B. CLARKE, a citizen of the United States, residing at Birmingham, 1n the county of Jefferson and State of Alabama, have invented a new and useful Apparatus for Handling Coal and Similar Material in Bulk, of which the following is a specification.

The invention relates to improvements in apparatus for handling coal and similar material in bulk.

The object of the present invention is to- V a portion of a barge provided with apparatus for handling coal constructed in accordance with this invention. Fig. 2 is a transverse sectional view. Fig. 3 is a sectional view on the line 33 of Fig. 2.

Like numerals of reference indicate corresponding parts in all the figures of the drawlugs.

1 designates a barge provided with transverse bulkheads 2 forming a series of bins 3, beneath which is arranged a longitudinal chute}, adapted to receive the contents of the bus and provided with an endless conveyer for carrying the contents of the bins to a suitable elevated point to enable the coal or other cargo to be delivered from such point by inclined chutes to the bunkers of a vessel to be loaded. Each bin is provided with the mechanism about to be described, so that only a descr1ption of one of the bins will be necessary; and the barge is divided into a number of transverse bins to facilitate loading from a wharf or pier, so that as soon as one bin or compartment is filled the-barge may be moved longitudinally to bring another bin or compartment at the place of supply. Each bln is provided with opposite swinging inclined dumping gates 5, extending from bulkhead to bulkhead and forming an oppositely inclined bottom for. the bin to direct the coal into the conveyer chute t, when horizontal sliding gates or cutoffs 6 are open for this purpose. 5 5

The dumping gates are hinged attheir bottoms at 7 at the sides of a horizontal bottom portion 3 and above the conveyer chute 4, and their tops or upper ends are connected to chains 8, which are wound around sheave-drums 9 of opposite longitudinal shafts 10; and they are adapted to be arranged at the desired angle or inclination to direct the coal into the chute and to cause the bin to be entirely emptied. The barge is braced and the parts are supported by horizontal and inclined timbers 11 and 12 and suitable connecting braces, and the inclined timbers 12 are arrangedto-supportthe dumping gates 5, when the latter are in their lowest position or at their widest angle. Thetopsofthedumpinggatesareguided by curved walls 13, and in order to prevent coal getting behind the dumping gates when the latter are raised beyond the upper termini of the curved walls 13, hinged guards 14 are provided. The guards Mare hinged at their upper ends to vertical walls 15 of the bin, and consist of long narrow plates disposed longitudinally of the barge and adapted to be engaged near their loweredges by the tops of the dumping gates to close the spaces above the latter, as indicated in dotted lines in Fig. 2 of the accompanying drawings.

The drums 9 are loosely mounted in pairs at the side of each bin on the upper longitudi nal shafts 10, and are provided with clutch sections 16 adapted to be engaged by corresponding clutch sections 17, which move longitudinally on the shafts 10 and are connected with them by keys 18,whereby when the clutch sections 17 are engaged with the sections 16 of the drums, the latter will be fixed to the shafts and will rotate with the same, and Wind up the chains 8 and raise the dumping gates. The movable clutch sections 17 are controlled by levers 19 with which they are connected by rods 20. Eachlever 19, which is arranged midway between the drums 9, is fulcrumed near its lower end on the barge, and has the rods 20 pivoted to it above and below the fulcruming points, in order that the clutch sections 17 may be simultaneously moved into and out of engagement with the other clutch sections. When it is desired to raise thedumpjacent edges of the sliding gates.

ing gates the levers 19 are moved to bring the dumping gate is elevated suiiiciently its lever 19 is released and the clutch sections 17 are disengaged from the clutch sections 16 of the drums by a spiral spring 21, which is connected with the lever 19. The drums are held against retrograde rotation, after the clutch sections are separated, to prevent the chains unwinding, by pawls 22 pivotally mounted at the upper edge or top of the bin and engaging ratchet wheels 23 arranged at the sides of the drums. The ratchet wheels 23 are preferably formed integral with the drums, but may be otherwise provided; and after the bin hasbeen emptied the pawls may be disengaged from the ratchet-wheels of the drums by the blow of ahammer.

Any number of sliding gates or cutoffs 6 may be provided in the bottom of the bin, and they are connected by horizontal rods 24 with levers 25 fulcrumed intermediate of their ends on a bearing bracket 26 and extending upward through a slot 27 in the deck of the barge and terminating in a handle.

The rear ends of the upper longitudinal shafts 10 are provided with pulleys 28 and connected by a belt 29; and one of the shafts 10 is connected by a belt 30 and pulleys 31 and 32 with a lower longitudinal shaft 33, which is similarly connected with a driving pulley 34 connected with any suitable power preferably an engine (not shown) designed tobe arranged in the stern of the barge or boat.

The lower shaft 33 extends longitudinally of the barge or boat adjacent to the bottoms of the bins and is connected by cog-wheels 35 and pinions 36 with countershafts 37, which carry agitators 38, operating through slots 39 cut in one of the dumping gates and the ad Each agitator 38 consists of a spider, or radial arm extending from the hub, and the rapid rotation of the agitator causes the coal to be quickly fed to the conveyer chute. Any number of agitators may be provided for each bin, but, preferably, three sets are employed, two agitators being on each countershaft, and the sets of agitators are controlled independently of one another, whereby the discharge or feed of coal may be readily regulated. Each countershaft is thrown into and out of operation by a'clutch 40 having one section secured to the cog-wheel 35, which is loosely mounted on the shaft 33, and its other section keyed to the shaft and having a limited movement to engage and be disengaged from the clutch section on the cog-wheel. The movable section of the clutch 40 is actuatedby a rod 41 extending rearward and designed to communicate with and terminate at the engine room; it is provided at its rear end with a handle 42; and it has adjacent to the handle a series of teeth forming a rack 43, which is adapted to engage a plate 44, whereby the clutch is held securely against accidental movement. The front portion 45 of the rod 41 is disposed at an angle to the rear portion of the rod, and is connected to the movable section of the clutch 40. The rods 41 gradually 'increase in length as the clutches 40 are more removed from the engine room; and it will be read1ly apparent that the agitators by being controlled independently of one another, one or more sets may be put in motion as desired, and the discharge of coal from the bins to the conveyer chute may be rendered uniform.

It will apparent that by the apparatus here in set forth, coal or similar material in bullc may be readily removed from a barge or Slinllar craft for transferment to the bunkers of a vessel without employing shovels and wheel barrows, or similar handling of the cargo. It will also be seen that the discharge of coal from the various bins of a barge or vessel is under complete control and may be readily regulated to render such discharge or feed to the conveyer chute uniform throughout the length of the latter.

It will be understood that changes 1n the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrific ng any of the advantages of this invention.
