- act description.

My lnvention relates to an improvement in hoisting and conveying devices; and .it comprises certain novel features which will be distinct drum, and both and. E are loose hereinafter described, and ed-out in the claims. 7

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 thefigures.

' Figure 1 is an elevation of a conveyer with my improvement applied thereto. Figs. 2 and 3 are elevations of the upper ends of the head and tail supports, taken at right angles to the position shown in Fig. 1. Figure t is a sectional plan of the lower half of the carriage, showing the various ropes which are attached to or run thereon; and Fig. 5 is a plan view showing the arrangement of drums preferred for operating my device. a p

In Fig. 1 I have shown my device as'applied to a conveyer in which a cable A is used as the trackway, and the description will be of the device as applied to such a conveyor, although it will be evident that my invention may be applied to any form of hoisting and conveying apparatus in which a carriage is employed running upon a trackway, whether that trackway be a cable or other flexible member or is composed of rigid bars or beams. In Fig. l the arrangement of drums by which the various cables are operated is shown in a diagrammatic manner, the preferred arrangement of drums being shown in Fig. 5, but being of such nature that the arrangement of the various ropes leading thereto would not be as clearly shown as is shown in Fig. 1. The sections E and E of the drum are, in effect, one drum separated by a slight flange, the partE being preferably of slightly larger diameter than the part E. Thepart B is', however, a

particularly point- Y on their shaft and turned by any suitable friction device.- As shown in Fig. 5, it is contemplated to turn these drums by friction devices between the gear K and the respective drums.

'As the exact construction of these drums and the means employed to turn them is immaterial and forms no part of my invention, fuller description is deemed unnecessary.

with means by which it may be moved along, as a traction-cable-B, which passes over suit:

able sheaves it, ,h, 72. and if, supported by? The carriage C is supposed to be pfovided I the head and tail-supports I H and leading to 'a drum 6'. This drum,-the corresponding 7 portion of w'hich is shown at B in Fig. 5, is

made in the form of a winch-headfthat is, it is made to receive one or more wraps of the traction-rope B'so that movement is applied to said rope by the friction of the rope upon the drum. The hoisting-rope F is wound upon a drum E and passes over one of the series of pulleys, h mounted upon the head-support,

and. extends to and about a pulley G, which is carried by the carriage. This pulley is in two parts G and G the hoisting-rope F passing about the part G one or more times, so as to have frictional engagement therewith, by means of which when the pulley G is turned in one direction the friction due to the wraps may be relied upon to pullout and lower the hoisting-rope. This hoisting or fall rope is shown as passing about the fall-block O and then over a pulley upon the carriage and having its end secured. to the fall-block. In addition to the above ropes I employ what I term an overhaulingrope D, said rope being an endless rope, which passes about the drum E and is operated by frictional engagement therewith, the rope passing as many times around the drum as is necessary tosecure the required amount of friction. This overhauling-rope passesone or more times about the part G of the pulley G, so that when theoverhauling-rope is caused to move in one direction or the other it will exert a pull upon the hoist or fall rope in a corresponding direction. The frictional engagement of the overhaulingrope and the fall-rope, with their respective parts of the pulley G, should be suificient to enable the weight of that part of the fall-rope i which extends between the carriage and the movement along the trackway and by operat:

ing the overhauling-rope the descent of the fall-block may be secured, whether the same is heavy or light, and the necessity for fall rope carriers between the carriage and the head-support is obviated. The two parts Gr,

and G constitute two rope-bearing members having a traction connection, and I do not wish to be understood as limiting the traction connection to the direct connection shown in the drawings as preferable. In effect, the use of the double sheave or pulley G amounts toan automatically shifting engagement between the overhauling-rope and the fall-rope, by means of which the overhauling-rope may be used to run out and lower the fall-rope. This enables the other rope. to extend from the fall-block to the hoisting-drum E, and thus obviates any necessity for a splice and makes it unnecessary to rely upon any other rope to take any portion of the strain due to the hoisting of the rope.

In Fig. 1 the sections B, E, and E representing the various drums are shown as separated and are lettered b, e, and c. In the. drawings I have shown the overhauling-drum and the traction-drum as being of the same size. The hoisting-drum is, however, shown as being slightly smaller than the other drums,

the object of this being to insure that the mo-V tion of the overhauling-rope shall be slightly in excess of that of the fall-rope in order to provide for a slight slipping of the two ropes upon the pulley G.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent 1.
