CHARLES M, HUSON, OF ST. LOUISQMISSOURL CABLE TRAMWAY.

SPECIFICATION forming part of Letters Patent No. 269,525, dated December 26, 1882. Application filed January 17, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES H. HUSON,of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Cable Tramways, of which the followingjs a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a tramway in which the buckets are automaticallyloaded and emptied; and my invention consistsin the hereinafter-described points of novelty.

in the drawings, Figure l is a top view of my improved tramway. Fig. 2 is a side elevation, part in section. Fig. 3 is an enlarged horizontal section of the clamp for securing the buckets to the cable; and Fig. at is an edge view of same and the upper portion of the bucket-pendant, showing the return-bend of the latter, so that the bucket is sustained vertically beneath the cable. Fig.5 is a vertical section of'the loading car on line 5 5, Fig. 2, and Fig. 6 is a similar section on line 6 6, Fig. 5. Fig. 7 is a horizontal section of-the car on line 7 7, Fig. 2. Fig. 8 is a horizontal section on line 8 8, Fig. 2, showing a top view of the cam for engaging with a pin on the bottom of the bucket to empty it. Fig. 9 is a horizontal section on 1ine9 9, Fig. 2, showing the yoke and rag-wheel for keeping the bucket-pendant in a vertical position while the bucketis being emptied. Figs. 10 and 11 are views illustrating the device for the intermediate support of the cable in cases of inclines and curves. Fig. 10 is a side elevation, and Fig. 11 is a detail edge view.

A and A represent the supporting-frames at the opposite ends of the tramway, A being the receiving end, and A the discharge end. The frame A supports a vertical shaft, B, in The driving-power is applied to this shaft by means of a bevelcog-wheel, O, on the shaft, engaging with a similar whe'el,D,on a horizontal shaft, E, having bearing in suitable boxes secured to the frame. On the shaftE is also the driving-pulley D.

On the vertical shaft B is'a flanged wheel, F, around which the endless cable F passes, and a rag or sprocket wheel, G, for engaging with the bails of the buckets as they move around the shaft.

H is a yoke secured to the frame A by its opposite ends, and inclosing the shaft above with this cam, which turns the buckets over,

emptying their contents.

A A are supporting-pulleys secured to the frame Anear the shaft B.

J are the buckets. pivoted to the bails J of the pendants J The buckets are so secured to the bails that when the pins J on their hottoms come in contact withthe cam I they will tilt freely. The pendants are bent, as shown in Fig. 4, so that the buckets are sustained directly beneath the cable, and at the same time the pendants do notstrike the frames supporting the pulleys or the pulleys themselves.

The pendants are secured to the cable by means of clutches K, to which their upper ends are secured. There is a hole through the body of the clutch, through which the cable passes.

The hole is made sufficiently large to receive a wedge. K, Fig. 3, which is driven'in above the cable, to keep the clutch from slipping on the cable.

There may be any number of the intermediate pulleys, L L, supported on suitable frames, L. I prefer to place over these intermediate pulleys automatic gates L to prevent all danger of the cables being thrown off the pulleys. It will be seen that as a clutch strikes the inclined face of the gate thisend will swing back from over the cable and the otherend swing forward and cover it. Then, as the clutch strikes the other end, it swings back and the other moves forward and covers the cable. The gates are prevented from swing- 5 ing completely around by stop-pins projecting up from the frame L.

M is a vertical shaft, supported in suitable bearings secured to the frame A. On this shaft is a rag-wheel, N, and a flanged wheel,

- T will close b gravity onthe return movement N, both of them being similar in character and purpose to those, F and G, on the shaft B. O 0 are supporting-pulleys secured to the frame A, for supporting the cable so that it will not bind on the wheel N.

I will now describe the automatic loading device.

P is a movable car, supported by grooved wheels P, traveling on a suitable track, Q. I prefer to make the body of the car of boileriron, to the top of which is secured a bail, R, connected to the shaft M by acollar, R, and connecting-rod R 7 S is a hopper secured to the body of the car, its inner end passing through an opening in the body. (See Fig. 5.) The opening is closed by a sliding valve or door, T, guided at bottom by brackets T T, secured to the body of the car, and at top by a rod, U, working in a crossbar, U, secured to the bail R.

To the bottom of the door T is secured a pin, T, which works on an inclined cam, T secured to the frame A, outside the car. As the car is moved forward by the traveling buckets the hopper-valve will be automatically opened by the pin bearing against the upper face of the cam. As the buckets move around the shaft M their pendants engage with a pin, V, projecting horizontally inward from a strap, V, secured to the inside of the body of the car. Thus the car travels with the buckets as they move around the shaft M, and, as the hopper will be opened as described, the material in the hopper will be dischargedintothe buckets. The track on which the car travels gradually inclines from the shaft in the direction of the forward movement of the car, (see Fig. 1,) which will cause the pin V to gradually retreat from the pendants of the buckets until it is released therefrom, when the carriage will travel back to its starting-point under the influence of a weight, W, secured to the car by a rope, W, passing over pulley W and under pulley W secured to the frame A. The valve of the car. When the car returns another charge of material is put in before the next bucket comes along.

As a modification of the rag-wheels G and N, lantern-wheels might be used, whose bars would engage with a pin projecting inward from the bucket-pendant.

In passing around curves it will be seen that it would be necessary to have some device to prevent the pendant coming in contact with the supporting-frame of the pulleys. To accomplish this I have arranged a spider, X, (see Fig. 10,) with flanged or grooved wheels X on the outer ends of the arms, over which the cable passes. The pendants will pass in between the arms as the clutches strike upwardly-projecting pins X on the end of the arms. (See Fig. 11.) It will be seen that only one of these spiders will be necessary in a horizontal curve, as shown in Fig. 10, for the pendants on the outside cable will pass on the outside of the wheel and not be interfered with by the supporting-frame of the wheels. In cases of vertical curves, the cable would pass under the spiders, and a spider would be necessary for each cable in this case, as the clutch would not pass between the cable and a common wheel. The pins X would not be necessary where vertical spiders are used. For a horizontal spider, flanged wheels would be used, but in vertical spiders the wheels would have to be grooved to prevent danger of the cable slipping off. Y

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a tramway, the combination of shaft, rag or sprocket wheel, and buckets, the wheel and buckets adapted to engage with each other, for the purpose set forth.

2. In a. tramway, the yoke H, secured to the frame A, in combination with rag-wheel G on shalt B, and cam I,secured to the frame, for engaging with pins on the bottoms of the buckets, substantially as and for the purpose set forth.

3. In a tramway, the combination of bent pendant J bail J, and bucket J, as set forth.

'4. In a tramway, the clamp for securing the buckets to the cable, consisting of body K and wedge K, substantially as set forth.

5. In a tramway, the automaticgates L se cured over the pulleys L, substantially as and for the purpose set forth.

6. In a tramway, the rag-wheel N, secured to the shaft M, for the purpose set forth.

7. In a tramway, the car P, supported by wheels P on track Q, and connected to the shaft M, substantially as set forth, with the hopper S and door T, automatically opened by the cam T and pin T pin V for engaging with the bucket-pendants, and weight W, with corn necting-cord W and pulleys W and W all substantially as and for the purpose set forth.
