COAL-TIPPLE.

SPECIFICATION forming part of Letters Patent No. 333,891, dated January 5. 1886.

Application filed September 29, 1885. Serial No. 178,580.

To all whom it may concern:

Be it known that 1, WILLIAM WV. RosEN- STEEL, of Vancefort, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Coal- Tipples; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side view of my improved tipple, and Fig. 2 is a plan view thereof.

Like letters and figures of reference indicate like parts in each.

In the drawings, 2 represents an inclined frame or trestle, on which are set the tippletrucks used in conveying coal and like merchandise fromthe bottom of the frame to its summit, where it is dumped into cars. The lower part of the tipple-frame is made broad enough to accommodate two tracks, 3 and 4,

placed side by side; but near the upper end it is made narrower, and the inner rails of the tracks cross each other, afrog, 5, being placed at the intersection. Atruck, 6, is mounted on each of the tracks 3 4, and each is provided with atraction-cable. The cable 7 of one truck is wrapped several times around the periphery of a'rotatory sheave or drum, 8,

j onrnaled in bearings above the summit of the tracks, and the cable 7 of the other truck is wrapped around a second sheave, 9, journaled end to end beside the sheave 8. The cables. after inwrapping the sheaves 8 and 9, pass downward to a common drum or roller, 10, to which they are affixed, and around which they are wrappedinopposite directions. The drum 10 is power-driven, and it is clear that as it r0- tates it will wind one of the traction-cables in one direction to raise the car, and will unwind the other cable, so as to allow its car to descend the track. By reversing the motion of the drum the cars are moved in respectively opposite directions from those just described, so that the trucks can be moved up and down the tracks at the will of the operator of the main drum. As one car moves up the track, the other descends, and vice versa, the meeting-point being below the frog (No model.)

5. At the upper end of the inclined tracks there is situated a truck, 11, the rear wheels of which are mounted on a section of track, 12. It has its platform in the same line with the track-frame 2.

On the bed of the truck 11 are two sets of rails, 13 and 14,which correspond to the tracksections 3 and 4, and when the truck is lowered to the position shown in Fig. 1, with its platform abutting against the end of the frame 2, the ends of the rails 13 14: and 3 4 are respectively in conjunction with each other.

In advance of the track-section 12 is another section of track, 15, which is considerably more inclined from the horizontal than the former, and on which the front wheels of the truck 11 are mounted. Thus constructed, when one of the trucks 6 is raised to the top of the trackframe 2 by the cable, it passes onto the platform of the truck 11, and the front wheels of the former truck engage a stop horn or bar, 16, at the forward end of the latter. Then further traction of the truck 6 will exert a strain upon the stophorn 16,and will move the truck far enough to cause its forward wheels to rise upon the tracks 15 into the position shown by dotted lines in Fig. 1. The upper truck, 6, is then in an inclined position, and upon opening its endgate 17 the coal will fall thereout into a chute, 18, whose receiving end is situ-. ate beneath the bed of the truck 11 and in the path of the falling coal. The bed of the latter truck is suitably cut away to allow passage of the coal, and the mouth of the chute projects within the vertical space between the upper track-frame, 2, and the lower tracks, 12. The delivery end of the chute 18 rests within the mouth of a basket-chute, 19, which is sus pended by rods or chains 20 20 from an up: per frame, 21, which constitutes the beam of a weighingscales. The frame 21 is arranged on a platform, 22, which, surmounts the track frame 2. A gate, 23, is pivoted to the sides of the basket-chute 19 at the ends of arms 24,-, so as to be capable of being lowered to close the chute and of being raised to open it. The gate is fastened by a chain, 25, to the track frame 2, so that when the chute is lowered, as shown by full lines in Fig. 1, the chain will uphold the gate and keep it open, and that when the chute is raised into the position shown in dotted lines the gravity of the gate will cause it to adjust itself at the end of the chute and to close the latter. The chute is thus raised and lowered by means of the cable 20, which passes around a drum, 27, on the weighing-frame 21,and is attached to a counter-weight, 26, which depends therefrom. This weight is sufliciently heavy to raise the chute, when empty, into the position shown by dotted lines. The periphery of the drum 27 is fitted with a brake-strap, 28, operated by a hand-lever, 29, by means of which the rotation of the drum and motion of the chute may be retarded or checked. Suppose, now, the basket-chute to be in the position shown in Fig. 1 by the dotted lines, and one of the cars 6 to have mounted the truck 11 and to have been tipped so as to discharge its coal into the chute 18. The coal will then run into the weighingchute, which is prevented from falling by pressure on the brake-lever 29, and is so held long enough for the operator to note the weight of the coal indicated by the scales. The brakelever is then released, and the weighing-chute descends of its own gravity,thereby automatically opening the end-gate 23, and allowing the coal to fall into a car, 30, set on a track underneath the chute.

Two other cars, 31 and 32, are shown in the drawings situate beside the car 30. They are utilized in receiving coal from the tipple, as follows: The bottom of the fixed chute 18 isa screen, and underneath it and extending lengthwise therewith is a chute, 33,which discharges into an auxiliary chute, 34., the end of which is situate over the car 30. The bottom of the chute 33 is also a screen of finer texture than the bottom of the chute 18, and beneath the former is a chute, 35, which discharges through a reflexed chute, 36, into the car 32. There is a valve, 37, in the bottom of the chute 34,which, on being opened, as shown in Fig. 1, causes coal descending this chute to fall through the bottom of the chute into the car 31, and when closed allows it to pass on into the car 30. Suppose the valve to be open. Goal then passing through the chute 18 will discharge its fine nut coal and dust through the meshes of its screen onto the chute 33, and the dust will fall through the latter onto the chute 35. In this way the coal will be sorted, the large lumps discharging into the car 30, the nut coal entering the car 31, and the dust or slack entering the car 32.

Where the inner rails of the tracks 3 and 4 cross each other, as shown in Fig. 2 and before explained, it is necessary to provide means for removing the traction-cables of the descending car out of the way of the ascending car after the latter has passed the crossingfrog 5. I do this by a peculiar method of wrapping the cables around the drum 10 and sheaves 8 and 9, beginning the wrapping at the outer ends of the drum and wrapping them toward the middle. Then, as the car descends, the cable, unwrapping, will move to ward the end of the drum and away from the path of the ascending car, whose cable trav els in the opposite direction toward the center of the drum and the inner end of its sheave. When the truck approaches the upper end of the tipple and rides the rails beyond their point of inward curvature, the traction-cable will 'be at the inner ends of its sheave and in a vertical line with the center of the ascending truck. In this way a lateral pull on the truck is prevented, the traction is made safer, and wear on the rails reduced to a minimum.

In the drawings I have shown the sheaves 8 and 9 ofconsiderable width,and having smooth surfaces, so that the inwrapping cable will follow the motion of the main coil on the drum 10. The same result may be had by using small grooved pulleys in place of the rollersheaves, and mounting them on shafts wormthreaded, so as to move them laterally thereon in the proper direction as they rotate with motion of the trucks.

The novel features of my invention are, the arrangement of the tracks 3 and 4, which cross each other at the frog 5, thereby enabling the upper part of the track frame or trestle to be made comparatively narrow, and permitting the use of a single tipping truck, 11, for both the cars 6. The use of the auxiliary truck 11 is also novel, and is useful,because the coal can be dumped through its bed directly upon the chute 18 clear of the cross-ties of the trestle, whereas in dumping directly from the trucks 6 the ties form a considerable obstruction and tend to break up the coal. Arranged in this way,the dumping of the coal is entirely under the control of the engineer, who operates the drum 10, and the cars can be dumped without nnhitching the traction-cables, as has heretofore been necessary. The result is a saving of labor and expense.

The remaining features of my invention are, the two sheaves or rolls 8 and 9 and the single drum 10, the two car-cables 7 and 7 inwrapping the drum in different directions from the ends toward the middle thereof, whereby a rotation of the drum in a single direction will move one truck up and the other truck downthe trestle, and will remove their cables out of the way where the tracks cross each other, as shown.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a coal-tipple, the combination of a truck, 6, mounted on a track, a traction-cable for moving the truck on the track, an auxiliary truck or car, 11, situate at the terminus of said track and having its bed flush therewith, so that the truck 6 may be drawn thereon, and a second inclined track, on which said truck 11 is set, whereby motion of the latter thereon will tilt the truck 11 and its superinr posed truck to discharge the burden, substantially as and for the purposes described.

2. In a coal-tipple, the combination of a truck, 6, mounted on a track, a traction-cable for moving the truck on the track, an auxiliary truck or car, 11, situate at the terminus of said track and having its bed flush therewith, so that the truck 6 may be drawn thereon, a stop, 16, on the truck 11 in the path of the truck 6, and a second inclined track, on which said truck 11 is set, whereby when the truck 6 mounts the truck 11 and engages the stop 16 the traction of the cable will tilt the latter truck and its superimposed truck 6 to discharge the burden, substantially as and for the purposes described.

3. The combination,in acoal-tipple,of an inclined trestle, 2, having several sets of tracks, 3 and 4, arranged thereon side by side, trucks mounted on said tracks and provided with traction-cables so arranged that as one truck ascends the track its fellow will descend, an auxiliary tipping-truck, 11, at the upper terminus of said tracks, for receiving the trucks 6, the inner rails of the tracks crossing each other above the passing-point of the trucks,

summit of the tracks, a driven drum or windlass, 10, situate below the same, and tractioncables 7 and 7, attached to said trucks, passing over the sheaves 8 and 9, and inwrapping the drum 10 in respectively opposite directions, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 27th day of August. A. D. 1885.
