UETTED STETEs PATENT OFFICE.
ALBERT LUCIUS, OF NEW YORK, N. Y.
IMPROVEMENT IN HYDRAULIC HOISTING APPARATUS.
Specification forming part 0f Letters Patent No. 118,031, dated August 15, 1671.
To all whom it may concer/n:
Beit known that I, ALBERT LUcrUs, of the city of New York, in the county and State of New York, have invented a new and Improved VHydraulic Hoist-ing Apparatus 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing; forming part of this speciiication, in which- Figure l represents a longitudinal central section of my improved hydraulic hoisting apparatus. Fig. 2 is a top view of the same.
Similar letters of reference indicate corresponding parts.
This invention relates to a new and simple apparatus for elevating and lowering platforms in hotels or warehouses by means of water, and has for its object to utilize the entire force of the water and not waste any, and to reduce the ap paratus to a small compass. The invention consist-s in the combination, with the hydraulic cylinder, of a piston, toothed rod, gear-wheels, and winding-drum, all arranged so as to produce the desired result in the most satisfactory manner.
A is a hydraulic cylinder or tube, closed at one, the back end, a, and open in front. B is a piston, properly packed and connected with a piston-rod, C, which is constructed as a rack. This gears into a pinion, D, hung in bearings b, that are cast to the front end of the cylinder in form of lugs. The arbor c of the pinion D carries a drum, E, of large diameter, to which the hoisting-rope G is fastened, and around which it winds. A roller, F, hanging also in the lugs I), bea-rs against the smooth face of the toothed piston-rod C, and keeps it in constant gear with the pinion D. The water is admitted at the back end4 of the cylinder A through a pipe, d, which is closed by a suitable valve. This valve is connected with a rope, e, extending up along the hoist-way, so that by `pulling it the water may be admitted. A water-discharge pipe, f, connects also with the back end ofthe cylinder, and has a valve which ca-n be opened by a rope, g.
The operation o f the machine is as follows: In opening the pipe d water is admitted to the cylinder A, behind the piston B, pushing' the same forward, and causing thereby the rotation of the drum and the windin g up of the rope Gr. The platform is thus elevated. When both pipes d and fare closed, the water will be conlined within the cylinder A t0 retain the piston, drum, and platform in any suitable position. When the pipe j' is opened the water gradually escapes and allows the platform to descend.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the cylinder A, piston B, v
rack, C, pinion D, drum E, and guide-roller F with each other, all arranged to operate substantially as herein shown and described.
ALBERT LUGIUS. Witnesses:
