MECHANISM FOR LIFTING Pl PjES OR RODS FROM WELLS.
SPECIFICATION forming part or wa recent no. 609,398, dated August 23, 1898. Application filed August 31, 1897: Serial No. 650,150, (No model.)
To all whom it may concern:
Be it known that we, GEORGE ALLsUP and GEORGE D. BARRY, citizens of the United States, residing at Barneston, in the county of Gage and State of Nebraska, have invented a new and useful Mechanism for LiftingPipes or Rods from WVells, of which the following is a specification.
This invention relates to mechanism for lifting pipes or rods from oil and other wells; and its object is to provide a simple and eiiicient mechanism by which the pipes or rods may be easily and quickly withdrawn from a well with the expenditure of little force and in which the clutches may be fitted over the pipe or rod and will alternately adjust themselves to grip the pipe or rod for the purpose of raising it.
With these objects in view the invention consists of the several details of construction and combination of parts, as will be hereinafter fully described, and particularly pointed out in the claims.
In the drawings, Figure 1 is a perspective view of our improved pipe or rod lifting mechanism in position for use. Fig. 2 is a perspective view of one of the clutches detached. Fig. 3 is a horizontal section through the upper end of the tripod.
Similar reference-numerals indicate similar parts in the several figures of the drawings.
1 indicates an open frame, preferably in the form of an equilateral triangle, each side of which is provided with spaced ears, (indicated by 2.)
3 indicates the legs of the tripod, which are pivoted at their upper ends between the respective ears 2. Each leg is beveled at its upper end on its inner face, as indicated at 4, and the beveled portions engage the sides of the frame and limit the spreading of the legs at their lower ends.
5 indicates links, one of which is secured in one of the apexes of the frame and the other midway the opposing side.
6 indicates a lever which is provided with an open portion 7 near its front end,and this lever is pivotally suspended from the frame 1 of the tripod by rods 8 8, which are pivotally connected at their lower ends to the respective sides 9 of the open portion of the lever and at their upper ends to the respective links 5. l r
The clutches are indicated by 10, and each consistsv of a link open at oneside and an arm 11, riveted or otherwise firmlysecur'ed to one end of the link. The link is formed from a fiat metal bar bent in such manner that the end 12, to which the arm is secured, is straight and the other end 13 is curved. The ends of I the bar from which the link is formed are cut arm 11 when the link is in its operative posion of the upper end of the link and in operation will cause the link to move laterally until the pipe or rod is in the corner of the link at the lowest side of the extension, and the pipe or rod will be more firmly gripped, as itwi'll be frictionally engaged by the side of the link as well as the knife-edge of the arm.
17 indicates two rods of unequal length ,pivotally connected at their lower ends to the 'outer ends of the respective arms and at their upper ends to the lever in advance of and to the rear of the open portion 7, respectively. In operation the tripod will be set up over the pipe or rod to be withdrawn and the clutches placed in position on the pipe or rod by moving the links sidewise from opposite directions, and the pipe or rod will pass through the openings 14L in the sides of the links, and the lower edge of the curved end of the link and the upper edge of the opp0- site end, or, rather, the knife-edged extension of the arm, will be in contactwith the pipe or rod. It will be seen, therefore, thatthe links extend diagonally across the pipe in opposite directions and that the arms 11 extend on opposite sides of the pipe at substantially a right angle to the links and incline downwardly at their outer ends from the link. If now the lever be rocked on its pivot, it is obvious that one clutch will move upward while the other is moving downward on a pipe, and
- vice Versa, and that in its upward movement each clutch will grip the pipe firmly and move it upwardly, while in the downward movement each clutch-will slip freely over the pipe. One clutch will therefore be lifting the pipe while the other is moving down on the pipe to get a fresh grip. The space between the sides of each link is sufficient to permit it to slip freely over joints in its downward movement, and when a joint is between the two clutches the sections can be separated, and the lower clutch will support the lower section and the upper clutch the upper section, and in this manner the sections can be separated without danger of the lower one falling back into the well.
It is obvious that by the use of our invention pipes or rods can be raised with ease and rapidity from wells of any description and with the expenditure of but little force. As the pipe or rod is raised it will pass up through the open portion of the lever and the open frame at the top of the tripod.
Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
Having thus described the invention, what is claimed as new is- 1. In a pipe or rod lifting mechanism, the combination with a supporting-frame, of a lever pivotally supported by the frame, elongated link clutches loosely fitted on the pipe or rod one above the other to grip it in their upward movement and slip freely over it in their downward movement, each link having a lateral extension at one end to engage the pipe or rod and connections between the clutches and the lever to simultaneously raise one clutch and lower the other, and vice versa, substantially as described.
2. In a pipe or rod lifting mechanism, the combination with a supporting-frame, of a lever pivotally supported by the frame, elongated link clutches loosely fitted on the pipe or rod one above the other, to grip it in their upward movement and slip freely over it in their downward movement, each link having a lateral extension at one end to engage the pipe or rod, an arm extending from the upper end of each link, and rods connecting the outer ends of the respective arms to the lever on opposite sides of its pivot, substantially as described.
3. In a-pipe or rod lifting mechanism, the combination with a supporting-frame, of a lever pivotally supported by the frame, elongated link clutches loosely fitted on the pipe or rod one above the other to grip it in their upward movement and slip freely over it in their downward movement, each link having an opening in one side to permit it to be moved sidewise over the pipe or rod, and an inclined lateral extension at one end to guide the closed side of the link against the pipe or rod, an arm extending from the upper end of each link, and rods connecting the outer ends of the respective arms to the lever on opposite sides of its pivot, substantially as described.
4. In a pipe or rod lifting mechanism, the combination with a supporting-frame, of a lever pivotally supported by the frame, oppositely-disposed link clutches loosely fitted on the pipe or rod one above the other, an arm secured to the upper end of each link, the in? ner end of each arm forming a lateral inclined extension of the end of the link to which it is attached, and having a knife-edge, and the outer ends of the arms being connected respectively to the lever on opposite sides of its pivots, substantially as described.
In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
GEORGE ALLSUP. GEORGE D. BARRY.
