Description

' the'statiouary one.

JOEL MOULTON, OF BOSTON, MASSACHUSETTS.

IMPROVED PIPETONGS.

Specification forming part ofLetters Patent No. 52,0455, dated January 16, 1866.

To all whom it 91mg/ concern:

Be it known that I, JOEL MOULTON, of Boston, in the county ot' Suffolk and State ot' Massachusetts, have invented an Improved lipe- Tongs 0r lVreneh; and I do hereby declare that the following, taken in connection with thedrawing which accompanies and forms part of this specification, is a description of my invention sutlcient to enable those skilled in the art to practice it.

rlhe invention relates to the construction of tongs and wrenches i'or grasping and turning metal pipe or other articles.

The shank ofthe movable jaw is made to slide looselyr -with respect to the stationary jaw, and isheld in place to grasp the pipe or other article to be seized by a lever or handle extending from the shank of the iixedjaw and vturning on a lulcrum-pin, one ace ot this lever opposite the fuleruin being made eccen.

tric to the pin,-a.nd in such manner that when the handle is turned outward from the handle ofthe movable jaw said movable jaw may slide freely, while, when it is brought up to the handle ot' the movable jaw, the eccentric face bites upon and holds the shank ofthe iuovablejaw in fixed position with respect to lt is in this construction thatthe invention consists.

A tongs or wrench embodying the invention is shown in the drawing, the parts being broken to clearly show the construction.

a denotes the fixed jaw; b, the slidingjaw, having a pin, c, which slides in a slot, d, in the shank c ofthe lixedjaw, and a shank, j', which slides in a yoke, f/, projecting from the shank c, the yoke and pin keeping the movablejaw laterally in position with respect to thejaw a. Atthe lower end ot' the shank c is a fulcrlun-piu, li, upon which is hung the lever-handle i', this` handle turning freely upon the pin, and having a' griping-face, k, Aformed eeeentrically to its fulcruun and in such manner that when tliehandle i is turned out from the-handle ol' the movable jaw, as Seel, by the red lines, the shank fand the mon hie jaw may slide freely, while by carrycarried outward-and the movable jaw slid to-` ward the pipe or other article to be held until both'jaws rest against it. rlhe lever is then carried toward the handle l, when the article Uwillb evgrasywd or held, as will be readilymunK- m derstood. WVhile, however, this hold will be sufficient to turn a nut, the grasp would not always be tight enough to hold a pipe tirmly enough to turn the same. The shank f may therefore be provided with a series ot teeth, into which teeth upon the lever shall mesh as they are brought into eontaet,in such manner as to carry the movable jaw toward the stationaryjaw by bringing together the handles, so that when thejawsare brought against the opposite surfaces ofthe article by slidingthey shall not only be held against such surfaces by bringing the handles together, but shall be made to pinch or bite upon the article with increasingforce by tightening the grasp upon the handles. By loosening the grasp a little the ljaws may then be allowed to slip round -uponthe pipe to take a fresh hold, to turn the same, as will be readily understood.

- I claiin- The construction of the tongs or wrench with the lixed jaw and shank e, sliding shank f, and lever '27, having a griping-face, and operating substantiallyv as set forth.

1n witness whereot I have hereunto set my hand this 21st day of November, A. D.,

JOEL MOULTON.
