FRANK HENDRICKS, Oil IiOS .i tNGFILES, fli'iLIFORNIA.
REVERSIBLE GASING-WRENCI-I.
To all whom it may concern:
Be it known that I, FRANK fl'lnnnmcns, a citizen of the United States, residing at Los Angeles, county of Los, Angeles, and State of California, have invented a new and useful Reversible Casing-Wrench, of which the following is a specification.
This invention relates to casing wrenches, and the main object of the invention is' to provide a wrench of this character which may be reversed in operation without removing the wrench from the casing. i frenches of this character are extremely heavy, and it is a difficult matter to handle them. The diameter of the casing which is received by the jaws of the wrench is often sixteen or eighteen inches, and the wrench is in consequence very heavy.
it further object of the invention is to provide for preventing the from crushing the casing.
Other objects and advantages will be brought out in the accompanying description.
Referring to the accompanying drawings: Figure 1 is a plan view ot the wrench showingit in position on the casing, the :asing being in section. Fig". 2 is a view similar to Fig. 1 showing; the jaws opened to pass over the casing. .liipg. "5 is a section on the line m -0: Fig. 1. dis a view similar to Fig. 1 showing the wrench in reverse position for unscrewing the casing.
The wrench comprises two jaws, 1 andv 2, each jaw having eyes 3 and l, either pair of eyes being adapted to receive a pin 5. The jaw 1 also has a bifurcated cye b, in which is pivoted a handle 7 by means of a pin 8. The jaw 1 has abutmcnts 9 and 10. The jaw 2 has a pair of bifurcated eyes 11 and 153. A curved link lit-i is adapted to be pivotally secured by a removable pin i l with citier of the eyes 11 or l2, and at its other end the link i3 pivotally connected loy a pin with the handle 7. The link 13 has a lug forming a stop it}, which is adapted to strike a 'zainst either oi. the abutments 9 or 10 to limit the opening moven'lcnt oi the jaws. The inner lacrci; each jaw may be constructed in any do l".[i manner; for example it may have a :iCFOE-i E' gripping; lugs ii, and also have a li'l'liPS of sharp edged rods .18 which are a 2st entirely received by slots in the jaws. but their sharp edges protrude slightly and serve to bite into the casing lit and previ'mt slippage. l lcll Specification of Letters Patent.
Application filed October 31, 1911.
be moved across tie casing.
Patented (let. 8, llltl llfd.
Serial No. 657,856.
In operation when the link 13 is connected with the eyes 12 and the pin 5 passes through the eyes l, as shown in Fig. 1, by operating the handle 7 to turn the jaws clockwise, the link 13 will draw in a clockwise direction on the eyes 12, while the pivotal point 8 will be moved countercloclnvise, thereby causing the jaws to close firmly around the casing, and continued turning of the handle 7 will result in turning, the casing clockwise and screwing it into position. If it is desired to loosen the jaws the handle 7 is simply moved in reverse dircctiomwhich will move back the link 1.3 and relax the jaws. This relaxing movement. is limited, however, by the stop 16 striking; the abutment 9, so that the jaws are only moved apart the slight distance necessary to relax them. If it is desired to remove the wrench the pin 5 may be withdrawn, whereupon the jaws 1 and 2 may be swung wide apart, hinging on theirpin 12. They are thus pormittcd to swing apart a suflicient distance to it it is desired to reverse the action of the wrench the jaws are first relaxed, the wrench being suspended by the chain which is attached to the eye 20, and the pin 5 is first placed in the eyes I then the pin 14- is removed and the pin 15 also, and the link 13 is lifted bodily and moved into the position shown in Fig. 1, after which the pin 14; is phued in the eyes 11 connecting that end of the link, and the pin. 15 is replaced to connect the other end of the link with handle 7. Ilriy then operating; the handle 7 in a clockwise direction, the link 13 will pull on the eyes 11 in a countcrclocl-iwise direction nd will move the pivotal point 8 in a clocki'visc direction, thereby contracting the jaws to grip the casing. To remove the wrench from this position the pin 14 may be withdrawn from the eyes 3 and the jaw .3 swung apart, as shown in Fig. 2.
ll hat I claim is:-- l. A reversible casing wrench comprising a pair of jaws, a handle pivoted to one jaw, a link deinchahly pivoted to said handlcnear one and, and means "for detachably pivoting the other end of the link to either oi said jaws.
it. it reversible casing wrench comprising a pair of jaws, a handle pivoted to one jaw, a link detachabiy pivoted to said handle near one end, means for detachably pivoting the other end of the link to either of said jaws, an abutment on each jaw, and a lug on said link forming a stop adapted to strike either 5 of said abutmen-ts. I
3. A reversible casing wrench comprising a pair of jaws, a handle pivoted to one of said jaws, each of said jaws having an eye at each end, a pin adapted to couple the 10 associated eyes at either end, a pair of outwardly projecting eyes on one of said jaws, a link, a pin adapted to pivotally connect one end of said link with either of the two latter eyes, and a pin adapted to secure the 15 other end of said link with said handle.
