HOISTING 'AND CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 505,637, dated September 26, 1893. Application filed October i 1892. Serial No.447.578. (NomodelJ To all whom it may concern.-

Be it known that I, PETER RASCH, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Hoisting and Conveying Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in hoisting and conveying apparatus; and it consists more especially in the combination with an elevated track, load-carriage mounted on said track and ahoisting and propelling rope or cable for propelling said carriage and provided with fall and tackle, of a second elevated track, a sheave-carriage mounted on said last-mentioned track, and operatively connected with the aforesaid hoisting and propelling rope or cable in such a. manner that said tackle maybe conveniently hoisted and lowered at any point along the route of the load-carriage.

In the accompanying drawings,Figure 1 is a side elevation of hoistingand' conveying apparatus embodying my invention. Fig. 2 is a top plan of the same. Fig. 3 is an enlarged top plan showing more clearly the sheave or carriage, G, the track upon which it is mounted, and the operative connection of said carriage with the hoisting and propelling rope or cable.

The figures, to reduce their size, have portions broken away.

In the drawings is shown an elevated bridge tramway comprising a bridge or truss, A, supported at or near its opposite ends by a pier or tower; B representing the front or outer pier or tower, and O the inner or rear pier or tower. Bridge or truss A shown is of the triangular variety, the upper chords a a and lower chord a being arranged parallel with each other and extending lengthwise of the bridge or truss, and tied and braced together in any suitable manner, the lower chord being located centrally of the upper chord and constituting a track for the wheeled load-carriage D. The rear or inner pier or tower sup ports the engine-house containing the machin- V cry for operating the hoisting and propelling rope or cable E, (shown in broken lines) where by the load-carriage is propelled and whereby the hoisting-bucket is elevated and lowered. The two ends of the hoisting and propelling rope or cable are attached to the loadcarriage, one end being attached, for instance, at e, whence it leads to and over a sheave, e at one end of the route, in the present instance, the inner or rear end of the route and thence returns and leads over sheave e secured to the top of the bridge or truss above the engine-house, whence it leads downward to and around drum E" (shown in dotted lines) in the engine-house, being usually coiled once or twice around said drum to give the necessary friction. The propelling rope or cable thence leads to and around another drum, E (indotted lines Fig. 1) also in the enginehouse, but in the opposite direction, and is coiled once or twice around said last-mere.

tioned drum to give the necessary friction. The rope or cable thence leads upwardly to and over sheave, 6 secured to the top of the truss or bridge above the engine-house and thence leads toward the opposite end of the route, in the present instance, toward the forward or outer end of the bridge or truss, to and over sheave (2 also secured to the top of the bridge or truss. The rope or cable thence returns and leads over a sheave, c of carriage, G, that is mounted upon a track, H, rigid with the top and arranged lengthwise of the bridge or truss throughout a portion of its entire length at least. From said sheavecarriage the rope or cable leads to and over a sheave e, at the forward end of the bridge or truss, leading over one or more intervening guide-sheaves, as the case may be, and from sheave e, the rope or cable returns to and leads over a sheave, 6 with which the load-carriage, D, is provided. At the loadcarriage the hoisting and propelling rope or cable is provided with fall and tackle, the rope or cable leading downward over sheave e of the tackle I that supports the hoistingbucket J and thence returning to the loadcarr iage, where it is secured, as for instance, at e V l K represents a rope or cable (shown in heavy broken lines) secured to the carriage, G,as at 70, and thence leading to and over sheave 70' at the top of the bridge or truss, and thence leading downward into' the engine-house to the hoisting-drum K where it is secured.

By the construction hereinbefore described, it will be observed that the load-carriage is propelled in the one direction or the other according as the propelling rope or cable is wound upon the one or the other of the drums E E and that, by means of sheave-carriage G and the manner in which said sheave-car- :riage is operatively connected with the hoisting and propelling rope or cable, the hoisting-tackle may be elevated or lowered at any point along the route of the load-carriage, it being merely necessary to wind or unwind rope or cable K upon or from hoisting-drum K according as it is desired to elevate or lower the hoisting-bucket. It will of course be understood that the hoisting-bucket is elevated by causing sheave-carriage G to be moved or propelled in the direction toward the rear or inner tower by winding the rope or cable K upon the hoisting-drum, and that the hoisting-bucket will lower by gravity and cause said sheave-carriage to move in the 0pposite direction upon permitting the hoisting-drum to rotate to unwind said rope or cable.

What I claim is- 1. In hoisting and conveying apparatus, the

combination with an elevated track, a loadcarriage mounted on said track and a l1oisting and propelling rope or cable for propelling said carriage, said rope or cable being provided with fall and tackle for supporting the hoisting-bucket, of a second elevated track, as at H, a carriage mounted on said second elevated track, said last-mentioned carriage being operatively connected with the hoisting and propelling rope or cable in such a manner that the hoisting-bucket may be elevated and lowered at any point along its route, being elevated upon the movement of said carriage in the one direction and lowered by gravity, substantially as set forth.

2. In hoisting and conveying apparatus, the combination with an elevated track, load-carriage mounted on said track, and a hoist ng and propelling rope or cable for propelling said carriage, and provided with fall and tackle for supporting the hoisting-bucket, of a second elevated track, as at H, a sheavecarriage mounted on said second elevated track, the sheave-carriage being operatively connected with the hoisting and propelling rope or cable in such a manner that the hois ing-bucket may be elevated or lowered at any point along the route of the load-carriage, and suitable means for propelling said sheavecarriage in the direction to elevate thehoisting-bucket, substantially as set forth.

3. In a hoisting and conveying apparatus, the combination with an elevated track, a load-carriage mounted upon said track,a single and continuous hoisting and propelling rope or cable for propelling said carriage in opposite directions and provided with fall and tackle, of a second elevated track, as at H, a sheave-carriage mounted on said track and operatively connected with the hoisting and propelling rope or cable in such a manner that the aforesaid tackle is elevated or lowered according as said sheave-carriage moves in the one direction or the other, and ahoisting-drum and rope or cable for propelling said sheave-carriage in the direction to elevate the aforesaid tackle, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 20th day of August, 1892.

PETER RASOH.
