Description
HENRY JOHN KAHNE, OF ASI-ILAND, KENTUCKY.
CHAIN WRENCH.
Specification of Letters Patent.
Application filed April 18, 1907. Serial No- 368,958.
Patented June 11, 1907.
To all whom it may concern;-
Be it'known that I, HENRY JOHN KAHNE, a citizen of the United States, residing at Ashland, in the county of Boyd and State of Kentucky, have invented certain new and useful Improvements in Chain WVrenches, of which the following is a specification, reference being had therein to the accompanying drawing.
-My invention relates to improvements in chain Wrenches or those especially designed for use upon pipes.
The object of the invention is to simplify the construction of devices of this character and thereby render them stronger, more durable and less expensive.
With the above and other objects in view the invention consists in the novel features of construction, combination and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved wrench; Fig. 2 is a detail edge view of the head of the same; Fig. 3 is a side view of one of the jaw plates; and Figs. 4 and 5 are sectional views through the sleeve, taken in planes at right angles to eachother.
The Wrench comprises a suitable handle 1 having a flat end 2 to two of the opposite faces of which are secured jaw plates 3 which form a tapered head. The two jaw plates 3 are similar, each having a reduced inner end or shank 4 corresponding in width to that of the end 2 of the handle, and a tapered or V- shaped outer end 5, the opposite inclined edges of which are serrated to provide gripping faces or jaws 6. As before stated, the
shanks 4 of the jaw plates are engagedwith the opposite side faces of the end 2 of the handle and they are securely fastened thereon by a surrounding sleeve 7 and two rivets or similar fastenings 8, 9, the latter of which also retains the sleeve in position. This sleeve is of rectangular form and of such size that two of its opposing faces engage the outer sides of the shanks 4 and its other two faces engage the edges of said shanks and the adjacent side faces of the end 2 of the handle. In the inner end of the sleeve are formed two inwardly projecting ribs 10 which fit squarely against the inner ends of the shanks 4 to relieve the fastcnings 8, 9 of strain and more securely retain the aw plates upon the handle. While said fastenings 8, 9 may be in the form of bolts, I preferably einplo pins or rivets which are passed through a ining apertures in the united parts and have their outer ends upset or headed, as seen in Fig. 2.
By constructing the jaw plates with the shanks 4 and securing them upon the handle by means of the sleeve 7 and the fastenings 8, 9, it will be seen that they will be effectively fastened and at the same time may be readily removed and replaced when they are broken or have become worn. Upon one side of the sleeve 7 are formed two integral ears 11 aperturcd to receive a cross pin or rivet 12 which serves to secure one end of a chain 13 between said ears. The chain 13 may be of any suitable construction and length, so that it may be passed around the pipe or other object engaged by the head of the wrench, and its free end is adapted to be adju stably locked by engaging one of its links with two spaced lugs 14 formed integral with the sleeve 7 upon its side which is opposite that carrying the cars 11. T hese lugs are in-. wardly and rearwardly turned and are of peculiar shape, as will be noted upon reference to Figs. 1 and 2, so as to receive one of the links of the chain and effectively hold the free end of the latter. 4
Having thus described my invention what I claim and desire to secure by Letters Patent is 1. In a chain wrench, the combination of a handle having one of its ends formed with flat opposing faces, jaw plates having shanks engaged with said opposing faces, a sleeve surrounding said end of the handle and said shanks, afastening passed through said sleeve, said shanks and said handle and a chain connected to one side of said sleeve and adapted to be adjustably connected to the other side of the same.
2. In a chain wrench, the combination of a handle having a flat end, jaw plates having shanks arranged upon the opposite faces of said squared end of the handle, a rectangular sleeve surrounding said squared end of the handle and said shanks and having at its inner end inwardly projecting ribs to engage the inner ends of said shanks, a fastening pin passed transversely through said sleeve, said shanks and said handle, a second fastening pin passed transversely through safd jaw plates and said handle, a chain oonnedted to one side of said sleeve and means upon the other side of said sleeve for engagement with said chain, substantially as described.
HENRY JOHN KAHNE.
