APPARATUS FOR HANDLING COAL.

SPECIFICATION forming part of Letters Patent No. 577,078, dated February 16, 1897. Application filed September 20, 1395. Serial No. 563,106- (No model.)

To all whom it may concern:

Be it known that I, EPHRAIM SMITH, of West New Brighton, in the county of Richmond and State of New York, have invented a new and Improved Apparatus for Handling Coal and other Matter, of which the following is a specification.

The object of the invention is to provide a new and improved apparatus which is simple and durable in construction, very effective in operation,and designed. for handling coal, ore, and. like material or for dredging or other purposes.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement with parts in section. Fig. 2 is a front elevation of the same. Fig. 3 is a sectional plan view of the same on the line 3 3 of Fig. 2, and Fig. 4 is a sectional side elevation of the conveyer and part of the elevator.

The improved apparatus is mounted in a suitably-constructed frame A, on which are pivoted the arms B, arranged horizontally and supporting at their outer ends circular bearings B, located one above the other and each containing adisk O, mounted to turn in said bearings. The disks 0 are provided with central openings, through which extend the frame D of an elevator D, mounted to slide vertically in the disks 0 and adapted to turn therewith. These disks serve as guides for the elevator-frame.

On the lower end of the frame D of the elevator is arranged ashaft E, carrying the lower sprocket-wheel of the endless-chain bucketelevator D, contained within the frame D, the said shaft E also forming a pivot for the casing F of a conveyer F, provided with a conveyer-screw F preferably of larger diameter at its discharging end than at its receiving end and mounted to revolve within the said casing F, the lower end of the conveyerscrew extending a suitable distance beyond .the outer end of the said casing, so that coal,

ore, and other material can be taken up by the projecting end of the screw and be moved along the latter inside of the casing to finally discharge the material at the inner end of the easing into the boxes D of the elevator D. The shaft F carrying the conveyer-screw F is journaled in bearings formed in brackets F and F secured to the upper and lower ends of the casing. as plainly indicated in the drawwas.

On the upper end of the conveyer-screw F is secureda beveled gear-wheel F in mesh with a beveled gear-wheel F formed on a spur-wheel F mounted to turn on a stud F secured on the casing F of the conveyer F. The spur-wheel F is in mesh with a gearwheel E, secured on the outer end of the shaft E, previously mentioned, the said shaft carrying'at its lower end the sprocket-wheels for the sprocket-chains D on which the boxes D of the elevator are attached. 7

The under side of the casing F is provided near its pivot end with a roller F adapted to travel on the ground, the floor of a boat, car, or the like to prevent undue friction when the casing is moved forward or backward or turned around with the elevator D. Now it will be seen that by the arrangement described the conveyer is articulated on the lower end of the elevator, and consequently any desired angle can be given to the said conveyer relative to the ground or floor whenever the elevator is raised or lowered. It willfurther be seen that when the elevator sprocket-chains D are set in motion the shaft E is rotated, and by the gear-wheels E and F and beveled gear-wheels F and F a rotary motion is given to the conveyer-screw F so as to move the material from in front of the said conveyer up through the easing into the boxes D to be raised by the elevator. It is further understood that when the elevator D is turned,

as previously mentioned, the conveyer moves with it to permit of engaging the lower end of the conveyer-screw with any portion of the material to be elevated.

The sprocket-chains D of the elevator D pass attheir upper ends over the sprocketwheel D secured on a shaft D journaled in the frame D and carrying at its outer end a beveled gear-wheel D in mesh with a beveled gear-wheel G, secured on a shaft G, journaled in the upper end of the frame D.

\Vith the shaft G is connected a drivingpulley G2 by means of a key engaging a keyway in the said shaft, so that the latter can slide up and down in the hub of the pulley G and always be driven by said pulley. The pulley G is connected by belt with suitable machinery for imparting a rotary motion to the said pulley, and the latter is held from vertical movement by a suitable bracket G attached to the frame A. The extreme upper end of the shaft G is connected by a swivel Gr with one end of a rope H, extending upward and passing over. the pulleys H and H to the rear part of the frame A, the opposite end of the rope carrying a weight 1-1 to counterbalance the elevator D and the conveyer F.

The boxes D of the elevator discharge at their upper ends and at the rear into a chute I, inclined transversely and secured to the frame D of the elevator D. The lower end of this chute discharges into a vertically-disposed chute J, fitted to slide in a bearing 1, formed near the lower end of the said chute I, and the lower end of this slidable chute J is provided with a friction-roller J, resting on a circular chute K, into which the material passes from the said vertical chute J.

Now it will be seen that when the elevator D is turned with the disks G revolving in the bearings B to bring the conveyer F to the desired part of the material to be elevated then the friction-roller J travels in the circular chute K, and consequently the chute J and the said chute K always remain in connection and the chute J likewise remains in connection with the chute I, so. that the material passes down the latter into the chute J and from the chute J to the chute K, attached to the frame A, and is delivered at the desired place at the lower end of the chute K. As the elevator D is counterbalanced, the workmen at the lower end of the elevator and conveyer F can readily raise or lower the said elevator or turn it around to bring the conveyer-screw into proper position for engaging the material.

It will be seen that by supporting the circular bearing on the pivoted arms B the whole elevator and its conveyer part can be swung to either side out of the way of an approaching vessel, the. The elevator is suspended at a point in the vertical axis of the elevator, so that the latter can be conveniently turned or raised or lowered to bring the conveyer to the desired angular position without stopping the movement of the buckets and conveyer-screw.

It will be seen that this device can be used for transferring coal from barges, boats, and cars to bins, or from the latter to steam vessels, and it can also be used for dredging and other purposes.

Having thus fully described my invention, I claim as new and desire, to secure by Letters Patent 1. An apparatus of the class described, comprising an elevator, guides in which the said elevator is mounted to slide, and bearings in which the said guides are mounted to turn, the said elevator being mounted to turn with said guides, substantially as shown and described.
