(ci. 25a-#1am 6 Claims.
This invention relates to a drilling lift particularly useful in connection with the drilling of oil wells or other deep bores, and the prime object of my invention is to provide a novel drilling lift comprising hydraulic cylinders or rams which actuate cables, the cables in turn passing over suitable shives, and are attached to a coupling member, which will be evident from the subsequent description. i
Another object of my invention is to provide a novel drilling lift in which a. flexible cable is attachedv at one end to a hydraulic piston in a cylinder, and a novel pack-ofi means for the cable so that the iluid under pressure in the hydraulic cylinder will not be dissipated due to the reciprocal movement of the cable into and out of the hydraulic cylinder.
A feature of my invention resides in the tele-v scopically mounted tubes which surround the cable, the one end of one tube being attached to the reciprocating piston, while another of the tubes is attached to the head of the hydraulic cylinder.
Another feature of my invention is the ease and simplicity with which my device may be mounted in a derrick, and further that the usual crown and traveling blocks are eliminated. Furthermore, the tools can be moved from the top to the bottom of a derrick with great rapidity and suiilcient force can be exerted on the pistons in the hydraulic cylinders to lift the required weights.
Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.
In the drawing Figure 4 is an enlarged fragmentary, longitug.4 dinal, sectional view of two of the nestable sleeves. j- Referring more particularly to the drawing. the numeral I indicates a usual derrick, and mydrilling lift comprises a pair of long cylinders 2, 3, which are xedly attached to diagonally opposite legs of the derrick. The detailed con-` struction of the cylinders 2, 3 is identical; theregre, only one will be described in detail.
A piston l is reciprocally mounted in each of the cylinders 2, 3, and this piston may be provided with suitable cups or other type of packing which may be found suitable. A iiexible cable 5 is attached at one end to the piston 4,' passes upwardly through the cylinder 2 or 3, and thence over a shive 6, which is suitably journaled on a frame or head plate '1. The companion cable 8 in the cylinder 3 passes over a similar shive 9, and both cables are then iixedly attached to a coupling member I0. Suitable lifting equipment is attached to the coupling member Illfall oi which is usual and well-known, and forms no part of this invention.
Fluid under pressure is moved into and out of the cylinders 2 and 3 through the pipes II, I2,- respectively, from a suitable pump, not shown. In order that this fluid may not escape from the cylinders 2, 3, while the cables 5 and 8 are moving up and down in the cylinders, I provide a plurality of nested sleeves, the lowermost one I3 being xedly attached to the piston 4. The uppermost sleeve I4 is xedly attached to the wall of the cylinder adjacent the top or to a head plate I5. The nested sleeves all interlock, as best shown in Figure 4. Each sleeve is provided with a packing Ii at the upper end thereof, which fits closelyin the adjacent sleeve, thus forming an effective seal, and preventing the leakage of uid past the walls of the various sleeves. A shoulder I'I on the lower end of each of the sleeves serves as an abutment to strike against the bottom of the adjacent sleeve, thus causing the sleeves to properly nest as the piston 4 moves upwardly .in the cylinder.
In operation, iiuld under pressure is pumped through the pipes Il, l2 into the cylinders 2 and 3. This forces the pistons l downwardly in each of the cylinders, and causes the coupling member I0 to move upwardly. withdrawing the uid, the pistons l will gradually move upwardly in the cylinders andthe coupling member III, with its attached load of drill pipe, and the like, will v move `downwardly.
Having-.described my invention, I claim:
' '1,.? A drilling lift comprising a pair of hydraulic cylinders, adapted and arranged to be attached tole'gs of an oil well derrick, a piston in each of the cylinders, a cable attached to each of the pistons,

4. A drilling liit comprising a pair of hydraulic cylinders arranged at an angle to the vertical, each oi' said cylinders being tlxedly attached to diagonally opposite legs of an oil well derrick, a piston in each of the cylinders, fluid intake and outlet means extending into each o! the cylinders above the pistons therein, said cylinders being each closed at the bottom, a cable secured at one end to a piston, a shive over which said cable extends, said shive being arranged adjacent to the outside of the cylinder. a coupling member, said cable being attached to the coupling member and nestable sleeves surrounding the cable and arranged within the cylinder, one of said sleeves being attached to the piston and another of said sleeves being attached to the cylinder.
5. In a hydraulic cylinder for drilling lifts, a piston reciprocally mounted in the cylinder, a plurality of nestable sleeves within the cylinder, one of the sleeves being attached to the piston and another o! said sleeves being attached to the cylinder whereby a packing is provided at the end of the cylinder.

In a hydraulic cylinder for drilling lifts, a piston reciprocally mounted in the cylinder, a plurality of nestable sleeves within the cylinder, one of the sleeves being attached to the piston and another of said sleeves being attached to the cylinder whereby a packing is provided at the end of the cylinder, and packing means on each oi' the sleeves bearing against the adjacent sleeve whereby a iluid tight seal is provided between said sleeves.
