PUMP-PIPE GRAPPLE.
SPECIFICATION forming part of Letters Patent N 0.702,334, dated June 10, 1902. Application filed January 3l, 1902. Serial No. 92.042. (No model.)
To @ZZ wbmit t may concern:
Be it known that we, LEVI N.SCHULTE and SAMUEL I-I. SCHUITE, citizens of the United States, residingA at Oregon, in the county of Holt and State of Missouri, have invented a new and useful Pump-Pipe Grapple, of which the following is a specification.
Our inventiouis an improved pump-pipe grapple adapted for usein raising and lowering pump-pipes from and into wells and for analogous uses; and it consists in the peculiar construction and combinatinof deviceshereina'fter fully set forth and claimed.
In the accompanying drawings, Figure lis a side elevation, partly in section, of a pumppipe grapple constructed in accordance with our inventionyshowing the cam-lever, shoejaw, and bail in 'the positions assumed thereby when disengaging a pipe. Fig. 2 is a perspective View of the same, showing the grapple engaged with a pump-pipe. In the embodiment of our invention `here shown we providejthe stock or body l, which is in the form` ofA a bar, has its lower end bifurcated to form a pair of depending ears 2, and has a rigid jaw extending from one' side of one of the ears, and the said rigid jaw is curved laterally in substantially semicircular form,was at 3. The upper portionof the stock l is provided with a guide-slot 4 of suitable v length. A lever 5 is disposed between 'the i ears 2 and pivoted upona bolt or pin G. The
outer portion of the said lever projects .outwardly from the stock oppositeto the rigid jaw 3 and is formed with an eccentric cam 7 at its inner end.` Ashoe-j aw 8 of arcuate form has its lower end pivoted between? theA lower ends of the ears 2 andunder the inner portion of the cam-lever by a pin or bolt 9. The said shoe-jaw is adapted to engage the periphery of the cam 7 and has its outer side grooved, as at 10, and provided with serrations ll to form a friction-surface.
grapple is as follows: The bail is engaged by the hoisting rope or tackle, and the pipe to be raised or lowered is engaged on opposite sides by the rigid jaw 3 and the pivoted shoejaw. The semicircular form of the rigid jaw formslan opening between one side of said rigid jaw and the shoe-jaw, which enables the pipe at any point thereof to be engaged by the grapple. The bail being raised by the hoisting rope or tackle, the outer end of the cam-lever-is raised by the links 14, which are drawnY upwardly with the bail, thereby causing the', eccentric cam to make apartial revolution, and the same being engaged by the shoe-jawSthe latter is pressed irmly against the-pipe, which is hence securely gripped or clutched between the rigid jaw and the shoejaw. The serrated and grooved engaging face ofthe shoe-jaw keeps the latter in engagement with the pipe and prevents the same from slipping either longitudinally of` the pipe or laterally with relation thereto. It will be understood that tle greaterthe length and weight of the pipe the more eiectually it will be gripped and clamped bythe grapple, and hence the same is eicient` for raising and lowering pump-pipes out of-and into wells and for other analogous uses. liVhen the grapple is lowered with reference to the pipe, the downward movement of the bail on the stock causes the outer end of the cam-lever to be correspondingly depressed, and the action of the cam with relation to the shoe-jaw is such that the shoe-jaw is disengaged from the pipe, as will be understood.
Having thus described our invention, we claiml. In a grapple of the class described, the combination of a stock having a'rigid jaw on one side, a cam-lever and a shoe-jaw pivoted to the stock, said shoe-jaw being disposed opposite the rigid jaw and adapted to bear against the cam, a bail connected to and longitudinally movable on the stock and a connection between the bail and the cam-lever, whereby the latter is operated by the bail, substantially as described.
2. In a grapple of the class described, the
combination of a stock having a rigid jaw on one side and a longitudinal guide-slot, a cam` lever, and a shoe-jaw pivoted to the stock, said shoe-jaw being disposed opposite the IOO rigid jaw and adapted to bear against the cam,
a bail, a connecting element pivotally con cam, a bail connected to and longitudinally movable on the stock, and a connection between the bail and the cam-lever, whereby the latter may be operated to operate the shoejaw, 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.
