SPECIFICATION forming part of Letters Patent No. 776,529, dated December 6, 1904.

Application filed June 6, 1901. Serial No. 63,3443. (N0 model.)

To It, wltom it may concern: 1

Be it known that I, TnoMAs SrnNonR MIL- LER, a citizen of the United States, and a resident of South Orange, in the county of Essex and State of New Jersey, have invented a new and Improved Hoisting Device, of which the followingis a full, clear. and exact description.

My invention relates to an improvement in hoistingdevices adapted to transfer goods, as from a vessel to a dock and other similar locations, and is especially designed for use in unloading coal and similar material, although it is equally applicable to use in handling other forms of material.

My invention comprises novel features, which will be hereinafter described, and particularly pointed out in the claims.

Figure 1 shows in front elevation two of my hoisting devices. Fig. 2 is an elevation of one of my hoisting devices, taken from the side or at right angles to that of Fig. 1. Fig. 3 is a plan view omitting the masts O and the ropes and other parts supported thereby. Figs. 4 and 5 are elevations at right angles, showing the elevated traveler or guide for the hoisting-rope. Fig. 6 is an elevation of the drum used for controlling the position ofthe boom.

My device is herein shown and will be described as employed for hoisting coal, ore, and similar material from a boat and deposit ing it in cars upon a dock. From this description its other uses will be evident.

In Fig. 2 a boat V, from which a load of coal or other similar material is to be taken, is shown as lying alongside a dock A. In the case shown the coal is to be delivered into cars O, which run upon one or more tracks G, extending parallel with the side of the clock. In this case the cars run upon an elevated structure a, as for coal-storage plants it is desirable to have the coal delivered at considerable elevation. This elevated structure carries tracks a, which lie outside of the tracks occupied by the cars while loading.

A platform B, upon which the hoisting-engines and other apparatus used in handling the material are placed. are supported above the tracks O, which carry the cars, by legs 5, said legs carrying Wheels I), which run upon the tracks a, so that the device may be moved along the (lock to any point where it may be needed. Of course where employed upon a different kind of work and under different conditions the elevated structure and the supporting-legs of the platform B may be dispensed with or modified. 1 have also shown the elevated structure as located a short dis tance back from the edge of the dock; but it is evident that it may be advanced to the dock margin, if desired.

Upon the platform or car B are mounted three rope-winding mechanisms and means for operating them independently. These mechanisms, as herein shown, consist of the drums (Z, d, and (Z the engines D and l). and the boiler I for supplying them with steam. The drum (6 carries the hoisting-rope G, the drum (Z carries the load-swinging rope F, and the drum (Z the boom-hoisting rope H.

The drum d is an ordinary friction-operated drum, and in many cases the drum d would. be of the same character, although where the bucket or load being hoisted is to swing back beyond the point of support of the hoisting-rope it might be desirable to have this drum reversible. Such a condition is shown in Figs. 2 and 3; but the swing of the bucket beyond its point of support is obtained by using a counterweight.

The drum (Z which carries the boom-hoisting rope, may be operated in any convenient manner, either by hand or by power, altl'iough I prefer a power connection. Such a device is shown in Fig. 6. The drum (Z is loosely mounted upon the shaft U of the drum (Z or any shaft which may be turned from the engine. A clutch (or equivalent device) composed of the two parts S and S, secured one to the drum and the other to slide upon but turn with the shaft U, is operated by a lever S so that the drum may be turned to wind up the rope when desired. Ratchetteeth T and dog T are provided, by which the drum may be held against backward rotation.

Pivoted to the car or platform li is a boom E, which is shown as having two side members, each of which is secured to the platform B at one side of the vertical plane in which the fall-rope swings, so as to be out of the way of said rope and the load carried thereby. These side members preferabl y incline to ward the swinging-rope F and are provided at their outer ends with a cross-bar, to which is secured the sheave f, constituting the tail-guide, over which passes the swinging-rope F. This rope is herein exemplified as an endless one, winding upon one side of the drum d as it winds off of the other side; but I do not wish to limit myself to the endless form. One run of this rope leads over vertically-placed guidesheaves 7r, carried by a bracket K, and thence leads beneath a sheave Z from which is suspended the counterweight K, which is shownto exemplify herein a form of tension device for the ropes controlling the guide L. The other run of this rope passes over the sheave f at the outer end of the boom and then back to a guide L for the hoisting-rope, the other run of the load-swinging rope connecting with said guide from the opposite direction. This guide consists of a frame carrying two pulleys or sheaves L, between which the hoisting-rope runs.

Extending in a row alongside of the path of travel of the car or platform B are a series of posts or masts O, which support a trackway-cable N, the cable at the ends of the series extending downward to anchorages or the end masts being provided with corresponding guys, as at a. Upon this trackway-cable, between each pair of masts, is placed a traveler or movable support for the sheaves carrying the boom-hoisting and load-hoisting ropes. This is shown in Figs. A and 5. This consists of a frame, as I, in which is mounted a single sheave 19, adapted to run upon the trackwaycable, and two sheaves g and /L at right angles to sheave 1), designed to receive the boom-hoisting rope H and the load-hoisting rope G. To the frame and extending oppositely are attached two traveler moving or steady ropes Q, which pass over sheaves R at the tops of the mast and then down to hand-winches Q. By these means the traveler may be moved to and held in any position on the trackway-eable and may thus be made to correspond with the position of the car B.

The iioor of the platform or car B has openings in line with the swing of the bucket M and hoppers 6 through which the coal may be discharged into the cars G beneath.

It is evident that by sufficiently extending the bracket K so as to act as a boom my device may be employed for transferring goods from a boat to a car or dock at the side of the device opposite that where the boat is. In such case it might be advisable for convenience to pivot the boom which corresponded with the bracket K. In the condition shown the bracket K is a short fixed boom. \Vith such a construction it would probably be dosirable that the engine D be reversible or the drum (Z be connected thereto, so that it might be reversed.

As shown in Figs. 2 and 3, the bucket M is caused to swing to its dumping position by the action of the counterweight. The counterweight is useful also to take up slack in the rope F, especially when the boom is raised. In case two booms were used extending oppositely the counterweight might preferably be located otherwise than at the outer end of the boom.

The operation of my device is as follows: The car or platform B is caused to travel along its tracks until opposite the point from which the loads are to be raised. If the ropes Q are loosened, the traveler will be moved to nearly the same point. By means of the ropes Q, the traveler may be properly placed and made fast. To hoist, the guide L for the load-hoisting rope is moved outward to the proper position by pulling in upon the lower run of the swinging rope F. i The bucket M is then lowered and when filled is hoisted, the rope F being operated to swing the load inward either while hoisting or after the bucket has been sufficiently raised. Unless the bucket may be permitted to drop somewhat while swinging in, the rope G must be drawn in somewhat while swinging the bucket in. When the bucket reaches the proper position, it is dumped into the hopper.

One important feature of my invention consists in the fact that the guide L is rope-supported, and although I have shown it as supported by the rope F, by which it is also moved, I do not wish to be limited to supporting it by ropes in this position or necessarily by the same ropes by which it is moved. Among the advantages of having the guide L rope-supported may be mentioned the fact that thereby is obviated any disaster from collision between the bucket and the guide should the bucket either by carelessness or intention be raised higher than the normal position of the guide, the flexibility of the rope support permitting the bucket under these conditions to push the guide L upward without disaster. Another advantage of the rope support consists in the fact that thereby the apparatus may be rigged largely of ordinary rigging appliances.

Another important feature of my invention consists in the fact that the runs of rope F operating and supporting the guide L are under substantially constant tension, and although I have shown the counterweight K as the tension device for this purpose I do not wish to be limited thereto. Among the advantages of such tension are the fact that the definite track, and a hoisting-rope, of an elevated trackway substantially parallel with the direction of movement of the engine, a guidesheave for the hoisting-rope adapted to be supported from and to be moved along said elevated trackway, and steady-ropes extending from said sheave toward each end of the trackway.
