WELL-TUBE LlFTER.
SPECIFICATION forming part of Mtters Patent No. 713,485, dated November 1 1, 1902.
Application filed May 15, 1902. Serial No. 107,388. (No model.)
To all whom. it may concern.-
Be it known that I, JOSEPH NEUMEI R, of La Crosse, in the county of La Crosse and State of Wisconsin, have invented a new and useful Improvement in WVell-Tube Lifters, of
which the following is a specification.
My invention is designed to provide an improved well-tube lifter for deep wells, the same being in the nature of a clutch for the well-tube to be connected with a grapplinghook at the end of a rope for pulling out a Well-tube or for raising or lowering the same.
It relates to that form of well-tube lifter in which the hook is connected to the outer end of a short lever whose inner end is hung upon an axial pin passing through the two jaws of a yoke embracing the well-tube and the inner end of which lever is formed as a clutch or cam-head adapted to pinch against the welltube when the outer end of the lever receives the pull of the lifting strain; and my improvement consists in such novel construction and arrangement of these parts as will permit these devices to clutch the side of a well-tube at any point along its length or will permit them to be reversed to lift the well-tube by loosely embracing the same at a point below the shoulder or enlargement of the couplingsection of the well-tube, as will be hereinafter fully described with reference to the drawings, in which- Figure 1 is aside elevation of mytube-lifter shown applied to a tube between its ends. Fig. 2 is a plan view of the same. Fig. 3 is a detail perspective of the clutch-lever. Fig. l is a detail perspective View of the clutchblock, and Fig. 5 is a side elevation of my tube-lifter reversed and shown applied for lifting a tube by its coupling-section.
In the drawings, A represents a section of well-tube.
B is a stout steel yoke embracing the welltube, and through the jaws of which yoke there passes an axial pin D, upon which is hung the short clutch-lever E. This lever has a hole (Z to receive the pin and on one side of it is formed a rigid cam-head E, whose outer faceis concaved to approximately fit the transverse contour of the well-tube. On
the other side of the head of the lever is a a clutch-block F, whose face is concaved and serrated to bind against and clutch the welltube. This clutch-block is hung upon a pin at f, Fig. 1, which passes through the lug of the clutch-block and the hole d of the lever. The lever E has a series of holes b near its middle, which receive the pin b of a clevis 0, into which latter the hook of the lift-rope is inserted. The object of this series of holes is to give to the clevis a variable leverage and to the clutch-block a variable bite against the well-tube. By adjusting the clevis away from the well-tube the leverage and bite are increased as may be necessary for lifting out very long and heavy well-tubes. At the extreme outer end of the lever a releasing-rope C is secured. Near the head of ,the lever there is formed on the same a lug e on one or both sides, which lug is adapted to cooperate with a stop-lug 6, formed on one or both jaws of the yoke 13.
In making use of my invention if the lifter is to be applied to any part of a section of tube the yoke B is first made to straddle the tube, then the lever E is placed between the jaws and the pin D inserted, the clutch-block F being on the upper side, as seen in Fig. 1. The lever E is sustained in the horizontal position shown in dotted lines by its lug e resting against the lug e of the jaws. Now when the lifting strain of the clevis is applied the lever E turns upwardly to the position shown in full lines, in which the clutch-block F is forced tightly against the well-tube, firmly clutching the same between the clutch-block and the side of the tube, so that the greater the lifting strain the tighter the parts are held. To release the clutch-lever, a pull on the rope C turns the lever on the clevis-pin b and loosens the grip of the clutch-block F.
If the well-tube is to be lifted by one of its couplings A, as seen in Fig. 5, then the yoke I3 and lever E are turned upside down, with the clutch-block on the lower side, in which it is out of service. The lever E then stands in a vertical position parallel with the wellsimple and practical device and is applicable to operating upon the well-tube in the difierent ways described.
Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is
1. In a Well-tube lifter, the combination with a yoke for embracing the well-tube of a clutch-lever having a loosely-pivoted clutchblock on one side, and a rigid cam-head with concave seat for the well-tube on the other side substantially as described.
2. In a well-tube lifter, the combination with a yoke for embracing the well-tube; of a clutch-lever having a rigid grappling-face on one side and a pivoted grappling-face on the other side and adapted to be reversed substantially as and for the purpose set forth.
3. A well-tube lifter comprising a yoke for embracing the well-tube, a clutch-lever hung between the jaws of the yoke and having a rigid clutch face on one side and a loose clutch-face on the other side, and a series of holes near its outer end, a clevis arranged in one of said holes, a releasing-rope secured to the end of the lever as described.
4. In a well-tube lifter, the combination of a yoke for embracing the well-tube, a clutchlever hinged between its jaws and having a series of holes near its middle and stop-lugs, as described, a clevis secured in one of said holes, and a releasing connection for the outer end of the lever for deflecting the latter and releasing its bite on the well-tube as shown and described.
