CONVERTIBLE ENGINE FOR DERRICKS AND CABLEWAYS.

SPECIFICATION forming part of Letters Patent No. '524,890, dated April 7, 1903. l Application iled November 13, 1902. Serial No. 131,190. (No niodelfl l A To all whom, it 11mg concern..-

Be it known thatl', ASHER LAMBERT, acitizen of the United States, and a' resident of Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in, Convertible Engines for Derricks and Oableways, of which the following is a full, clear, and exact description.

That my invention may be fully understood it is explained that in practice the endless traversing rope or haul-rope of a cableway isgiven a few turns around its drum,

In derrick-engines, on the contrary, the drums are cylindrical, the ropes being wound up or allowed to unwind, as desired.- Again, the

Lambert cableway system enables a drum of large diameter to be employedfor the traversing rope or haul-rope to obtain high speed of travel for the carriage, while a drum in a corresponding position in a derrick is required to be of small diameter to-obtain power.

My invention provides means whereby a contractor can readily convert his cablewayengine into a derrick-engine, and' vice-versa. My invention will be particularly described hereinafter and then defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the ligures.

Figure 1 is a side elevation of a cableway, showing diagrammatically an engine having differential drums arranged to actuate the traversing rope or haul-rope and the hoisting-rope or fall-rope. Fig. 2 is a perspective viewof the engine, showing a compound drum embodying my invention. Fig. 3 is a transverse sectional view of the pair of drums of the engine, the sectional exterior of the compound drum being shown in wend elevation; and Fig. 4 is a perspective view of one of the exterior sections of my improved drum.

That the utility of my convertible engine may be the better understoodl have illustrated in Fig. 1 a cableway having diiferential drums A B, the drum A being the larger and serving to actuate at a high speed the endless traversing rope or haul-rope 10,which moves the carriage 15, while the smaller drum B is shown as arranged to actuate the fall-rope or hoisting-rope 20. This cableway drum.

system is particularly described in an application iled by me concurrently herewith, Serial No. 131,191. The drums A B (shown best in Figs. 2 and 3) are suitably driven and controlled by actuating and controlling devices of any well-known form. -As shown, the drums have teeth o. b, which mesh with a pinion` C on a shaft C, said shaft being driven from the engine D in the usual manner. Therdrum A is made up of a'cylindrical body or core A and a sectional cylindrical exterior shell or auxiliary drum 'A2. The body A' preferably is equal or nearly equal in diameter to the drum B vof the pair' and otherwise are lateral flanges a2, having holes d5 for receivingwthe bolts l-that clamp the sections together, and at each end of each section in line with the bore are -iianges a4, which when the sections are together form annular lianges at each'end. These annular flanges extend parallel with the cylindrical core or body A and serve to increase the bearing-surface of the sections As on said core A. The peripheral surface of the auxiliary drum A2 is concaved to accommodate the endless traveling rope and prevent Vit from running off the y With an engine thus equipped when employed on a cableway the larger compound drum A ofthe pair receives, as stated, the endless traversing rope 10, which is given several turns/around said drum and otherwise arranged in a well-known manner, while the fall-rope 20 is connected with the smaller drum B'. Thus the larger drum may be made -to move the traversing rope at a high speed.
