HOISTING AND CONVEYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 505,639, dated September 26, 1893. l Application filed November 21,1892. Seal No. 452.729. (No model.)`

To all whom it may concern,.-

Be it known that I, PETER RASCH, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hoisting and Conveying Machines; 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-machines, and it consists more especially in a machine of the variety indicated, wherein two winding-drums are employed for actuating the hoisting and propelling rope or cable and wherein a third winding-drum is employed for actuating a separate and shorter rope or cable that is suitably connected with the hoisting and propelling cable in such a manner that when said last-mentioned drum is rotated in the direction to wind said shorter cable upon it, a portion of the hoisting and propelling rope or cable will be taken up, thereby effecting the hoist of the load, and when said drum is rotated in the opposite direction the hoistingbucket will be lowered; wherein, none of said drums are mounted on the driving-shaft, but wherein the hoisting and propelling rope or cable actuating-drums are loosely mounted on separate shafts, respectively, that are provided with gears meshing with a pinion operatively mounted on the driving-shaft, and wherein the winding-drum for actuating the shorter rope or cable for taking up a portion of the hoisting and propelling cable, is loosely mounted on one of said separate shafts, and wherein suitable clutch-mechanism is provided for each winding-drum for efecting the operative connection of the drum with the driving-shaft, whereby any one of said drums can be operatively connected with the driving-shaft Without affecting the remaining drums; whereby the winding-drum for actuating the cable to take up a portion of the hoisting and propelling cable and either one of the winding-drums for actuating said hoisting and propelling cable may be operatively connected with the driving-shaft at the same time, and my invention consists more particularly in the arrangement of parts wherein the driving-shaft is locate'd centrally midway of and arranged parallel and in the same horizontal plane with the shafts upon which the winding-drums are mounted and wherein the drums for actuating the hoisting and propolling cable are mounted upon their respective shafts in the same vertical plane so that the hoisting and propelling rope or cable that winds upon said drums in opposite directions, respectively, can wind from one drum directlyonto the other, when in operation,-of course, unwinding from one drum while winding upon the other; wherein all the parts are as compact as practicable, and at the same time form a machine thatis exceedingly simple in construction and convenient, durable and well balanced.

My invention also consists in the means employed whereby when the clutch-mechanism of the one hoisting and propelling cable winding-drum is actuated to operatively connectsaid drum with the driving-power, the clutch-mechanism of the other hoisting and propelling cable winding-drum will be simultaneously actuated to operatively disconnect said drum from the driving-power.

My invention also consists in certain features of construction and in combination of parts hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure l is` a side elevation of an elevated bridge tramway in connection with which my improved hoisting and conveying machinery is adapted to be used, showing the location of the driving-machinery, and Fig. 2 is a plan of the same, portions being broken away in said iigs ures to reduce the size of the drawings. lilig.r

3 is a plan View exhibiting the driving-shaft,

winding-drum for actuating the hoisting and'` propelling cable and winding-drum for actu-uf;

ating the cable or rope employed for-takings,

up a portion of the hoisting and propelling'fj p..

rope or cable, exhibiting also other parts and details hereinafter described. Fig. 4 is a l, front side elevation relative to Fig. 3,. and

Fig. 5 is a left hand side elevation relative to Fig. 3, partly in section on line 5 5, Fig. 3.

i Referring rst, to Figs. l and 2, A represents the truss or bridge of an elevated tramway, which bridge or truss is supported at Aleading to a sheave e3 at one end of the route;

thence returning and leading to and over a sheave gof a carriage, G, mounted on a track,

, G', on top of and parallel with the truss or bridge. From sheave g the cable again returns a suitable distance to and over a sheave e4 whence it passes to and over a sheave e5 above the engine-house downward to and over the one actuating winding-druln W in the engine-house and after being coiled twice or thrice around said drum to give the necessary friction, leads from said winding-drum to and coils a few times around the adjacent windingdrum, W', but coiling around said last-mentioned drum in the opposite direction, and thence the cable leads upward to and over a sheave, e6, at the top of the truss or bridge whencethe cable leads to and over a sheave, e7, at the opposite end of the route and thence returns to the load-carriage where it is secured at e. The direction in which theloadcarriage is propelled therefore depends upon the windingdrum actuated to wind up the hoisting and propelling rope or cable. H represents a rope or cable attached to carriage G on top of the truss or bridge and thence leading to and over a sheave h secured to the bridge or truss above the engine-house whence rope or cable H leads downward to and around a winding drum W2 in the enginehouse where it is secured. It is quite obvious that when said drum NVQ is actuated to wind upon or unwind the cable from said drum vmore or less of the hoisting and propelling rope or cable is taken up, to elevate or lower the load or hoisting-bucket, as required.

The arrangement of the winding-drums is very clearly shown in Figs. 3, 4, and 5, to which reference is now made, wherein I represents the supporting-frame and K represents the driving-shaft that is journaled in su-itableboxes, 7c, rigid with said frame, said driving-shaft being located centrally of and extending transversely of the supportingframe. Upon and centrally of the drivingshaft is operatively mounted a driving-pinion, K', that is in mesh with two spur-gears L M at opposite sides of the pinion, respectively,l and Ioperatively mounted on shafts, L, M, respectively, that are arranged parallel with and in the same horizontal plane with the driving-shaft and have bearing in suitable boxes, Z, fm, rigidly secured to the supportingframe, gears L M having the same diameter. The drums around which the hoisting and propelling cable winds, are loosely mounted at the same side of the respective gears L M upon their respective supporting-shafts L M, with which shafts they (the drums) or gears are adapted to be operatively connected by suitable clutch-mechanism N that may be of any well known construction. The clutchmechanism shown comprises a sliding-sleeve or collar n (commonly had in clutches) on the respective winding-drum supporting-shaft, said sleeve having laterally projecting pins n that are adapted to be embraced by the slotted or free extremities O of the forked end of a rock-arm O that is operatively mounted on an oscillating-shaft P that is located below and extends at right angles to the driving-shaft and has bearing in suitable boxes P rigid with the supporting-frame.

An operating shaft P and rock-arm O are provided for each clutch-mechanism, and each of said oscillating-shafts is provided with a bentlever that is operatively mounted in any suitable manner with a lever (not shown) in the operative or engineers cage or stand. sents the operating bent lever for drum W, and w represents the operating bent lever for drum W. The drawings illustrate the one lever w in the position that it occupies when the clutch-mechanism, with which it is operatively connected, is performing its function, and the other lever w is shown inv the position that it occupies when the clutch-mechanism, with which it is operativelyconnected is idle. Said levers are operatively connected with each other, preferably by the means shown in Fig. 5, wherein S represents a tilting release-lever that is fulcru med atits central portion, as at S', to a bracket S2 rigid with the supporting-frame. Said tilting-lever, at each end, terminates in an eye, S3, to which are attached chains T that, at their opposite ends, are attached by means of eyebolts T with the respective operating-levers at or near the outer ends of the latter. By the means just described it is quite obvious that the one winding-drum will be operatively disconnected from its rotating supporting shaft or driving-gear of the shaft simultaneously with the operative connection of the other winding-drum with its rotating supporting-shaft or gear for driving said shaft. It will also be observed that, supposing that the hoisting and propelling rope or cable winds around the one of said winding-drums and thence winds upon the other drum, in the opposite direction, however` on said last-mentioned drum, the rope or cable will Wind upon the drum that is operatively connected with its supporting-shaft and will unwind from the other winding-drum that is operatively disconnected from its supporting-shaft, and that the hoisting and propelling rope orcable, and consequently the load-carriage will be actuated or propelled in the one direction or the w repre- IOO IIO

other according to the winding-drum that has been operatively connected with the drivingshaft. 10 and 11 represent the brake-band and clutch-mechanism respectively, for windin gdrum W2. Said brake-band and clutch-mechanism may be of any suitable construction. The clutchmechanism; shown comprises, as usual, a sleeve or hub, 12, 4that Vat opposite sides has laterally -tprojecting pins 13` embraced by the slotted extremities of the forked end of a rock-arm 14 operatively mounted on an oscillating-shaft, 15, that extends at right anglesto the Winding-drum supporting-shaftV andlhas. bearing in suitable boxes, 16, rigid with the supporting-frame.

drum W2, extends parallel with the supporting shaft of said drum, and has suitable bearing in boxes, 18, rigid with the supportingframe. Upon said shaft is operatively mounted a bell-crank, 19, to each arm whereof is attached one end of the brake-band 10 of said drum so that said band Will `be tightened or loosened according as the bell-crank is actuated in the one direction or the other. Said shaft is also provided with an oscillating bent arm or lever, 20, that at its outer end, is operatively connected,by means of a link, 21, with a rock-arm, 22, operatively mounted on oscillating-shaft, 15. The latter is provided with a T-shaped lever, 28,-having two arms, 24, extending in opposite directions-the outer ends of said arms being operatively connected by means of cables or in any suitable `manner with levers (not shown) in the engineers or operatives case or stand. It will, therefore, be observed that the brakeband and clutch-mechanism of winding-drum W2, Vwill be simultaneously operated, the one always being applied While the other is released.
