OORNELE G. ROSS, OF RUTLAND, VERMONT, ASSIGNOR TO THE LINCOLN IRON WORKS, OF SAMEPLACE.
DERRICK.
SPECIFICATION forming part of Letters Patent No. 302,035, dated July 15, 1884.
' Application filed May 21, 1884. N6 model.)
To all whom. it may concern.- v Be it known that I, CORNELE G. Ross, of
Rutland, in the county of Rutland and State of The object of my invention is the operation.
of dcrricks more conveniently and rapidlythan heretofore; and it consists in a combination of worm and friction gearing whereby the mast and boom of a derrick can be turned at the same time a load is being raised or lowered, as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in'which similar letters of reference indicate corresponding parts in both the figures.
Figure 1 is aplan view of a derrick with my improvements, the boom and mast being cut off, and Fig. 2 is aside elevation of the same.
The bed-frame ,S and the winding-gear M for raising and lowering the load may be of any usual construction.
H is the running-shaft driven by suitable connection to a prime mover.
I is the mast, and Kthe boom. On the socket of mast I is keyed aworm-wheel, F, and at the side of frame S is mounted a horizontal shaft, D,whioh at one end carries a worm, E, engag ing wheel F, and at the other end of shaft D is a bevel friction-wheel, G. On the runningshaft H are two bevel friction-wheels, A B, connected by a loose sleeve that is fitted to slide on the shaft, but connected thereto by a feather and groove.
R is a lever connected by a rod, L, to the sleeve,-so'that either friction-wheel A B may be brought into contact with wheel 0. The shaft D may thus be made to turn in either direction, and by its connection to worm-wheel F, the mast correspondingly turned, and the boom with its load swung to right or left. It will be seen that this may be done while the hoisting-gear M is' being operated to raise or to lower the load, the shaft H driving both sets of gearing either alone or independently.
Having thus described my invention, I claim as new and desire to secure by Letters'PatentF 1. In a derrick, the combination of worm wheel F, worm E, and shaft D, operated from the running-shaft, combined with the mast and hoisting mechanism, substantially as described.
2. The combination in a derrick, of hoistinggear M, running-shaft H, lever B, frictionwheels AB (land shaft D, having connections for turning the mast, all substantially as shown and described. I
3. The combination, in a derrick, of mast I, worm-wheel F, worm E, shaft D, frictionwheels ABC, operating-shaft D, and lever B, substantially as described, for' operation as specified. I
