insrnn PIPE WRENCH.

Application filed me 13,

To all whom it may concern.

Be t known that I, l VILLIAM A. ELLIsoN, a citizen of the United States, and resident of Salem, county of chusetts, have Essex, State of Massainvented an Improvement 111 Inside Pipe lVrenches, of which the followmg description, in connection with the accompanying drawing, is a specification like characters on the parts.

This invention relates to wrenches and it has for a novel wrench of this character simple in its construction and while easily manufactured, and which is also very effective in operation.

drawing representing like inside pipe its object to provide which is 11 can be The features wherein the invention resides will be more fully hereinafter set forth and then pointed out in the appended claims.

in the drawings Fig. 1 is a side view of an wrench embodying my invention.

inside pipe Fig. 2 is a longitudinal sectional view taken on substantially the line 2-2, Fig. 3. Fig. 3 is a section on the line 3-3, Fig. 2.

Fig. 4: is a section on the line l4, Fig. 2.

My improved pipe wrench has a body portion 1 which is formed at one end with a portion 2 adapted to enter the pipe 3 to be turned. The body plurality of 1 is provided with a grooves 4 extending longitudinally thereof, the portions of the grooves formed in the pipe-ent ering end 2 having inclined bottoms or being of progressively decreasing depth from the end of said portion 2, as shown at 5.

Situated in the groov preferably es are jaws 6 which project beyond the portion 2,

each jaw having a shank portion 7 extending longitudinally of the bod formed at its end with 6 is also formed with the in 9 which engages the inc straight inside of the pipe of the inclined bottoms inclined faces 9 of the fac y l and being a. head 8. Each jaw clined inner face lined bottom 5 of the corresponding groove and the jaws have the sharp gripping edges 10. The jaws are preferably made as shown in the drawings with parallel top edges which engage the over the entire le ngth of the jaw lying within the pipe.

By reason -5 of the grooves and jaws it will follow that movement of the jaws to the left will cause them to be expanded by the engagef the groove.

e 9 of each jaw with This jecting beyond the periphery 1922. Serial No. 567,952.

causes thejaws to have a combined movement both longitudinally and transversely 1 of the axis of the body and causes the top edges of the jaws to slidably engage the inside of the pipe. Since the edges 10 are sharp the sliding movement will assist the edges to cut into the pipe to give a firm grip. On the other handwhen the aws are moved to the right they canmove toward each other.

The jaws are given their movement to the left by means of a nut 11, which is screw threaded to the body 1, the latter having the screw-threaded portion 12 for this purpose, said nut engaging the heads 8 which project beyond the periphery of the body 1. By turning the nut 11 to the left it will, act against the heads 8 and thereby move the jaws to the left, such movement operating to expand the jaws as above described.

The body 1 is provided with the fiat sides 13 so that it may be gripped witha wrench if desired. 7

In using the implement the collar 11 will be screwed to the right and the jaws will be moved forwardly so as to allow them to be carried toward each other sufiiciently to enter the pipe 3 to be turned. After the jaws have been entered into the pipe then the nut 11 is turned to the left thereby Withdrawing the jaws and expanding them into firm gripping engagement with the inside of the pipe. When the jaws have firmly gripped the pipe then a wrench may be applied to the flattened sides 13 of the body and the latter may be turnedthereby to turn the pipe 3 in either direction.

My improved device is very simple in construction and can be inexpensively manufactured and yet it is effective in operation.

While I have described a selected embodiment of the invention I do not Wish to be limited to the constructional features shown.

I claim:

1. In an inside pipe wrench, the combina- 100 tion with a body having longitudinal grooves of progressively varying depth at one end, of jaws occupying said grooves and having inclined faces to fit the inclined bottoms thereof, each jaw having a head pro- 105 of the body, and a nut screw-threaded to the body .and engaging the heads for moving the jaws in a direction to expand them. 7

2. In an inside pipe wrench, the combination with a body having a reduced end adapted to enter a pipe, said body having oppositely-disposed grooves extending longitudinally thereof, and the grooves at the reduced end having inclined bottoms, jaws occupying said grooves and each having at its end a head extending outwardly beyond the body, and a nut screw-threaded to the body and engaging said heads.

3. An inside pipe wrench comprising a body stationary with reference to the pipe being operated upon, having longitudinal grooves of progressively varying depth at one end, said grooves being deepest at the end "farthest within the pipe, jaws occupying said grooves having inclined bottom faces to fit the inclined bottoms of the grooves and outer faces lying parallel to one another, and means attached to the jaws for moving the jaws through the grooves to give said jaws a combined movement both longitudinally of and transverse of the axis of the body to cause said top edges to engage the inside of the pipe.

4i. An inside pipe wrench comprising a body stationary with reference to the pipe being operated upon, presenting inclined portions, jaws movable longitudinally of the pipe having inclined faces for engagement with the inclined portions of the body and having other parallel faces for slidable en gagement with the inside of thepipe, and means attached to the jaws for moving the jaws to cause the inclined faces of the jaws to slide over the inclined portions of the body thereby to give said jaws a combined movement both longitudinally of and transverse of the axis of the body whereby the parallel faces are caused to slidably engage the inside of the pipe over the entire area within the pipe.

In testimony whereof, I have signed my name to this specification.

WILLIAM A. ELLISON.
