UNITED STATES:
f'aor a WILLIAM A. ELLISON, OF SALEM, MASSACHUSETTS, ASSIGNOB TO DAVID E. MURPHY, OF SALEM, MASSACHUSETTS.
PIPE WRENCH.
Application filed November 9, 1922. Serial No. 599,819.
To all whom it may concern:
Be it known that I, WILLIAM A. ELLISON,
a citizen of the United States, and a resident of Salem, county of Essex, State of Massachusetts, have invented an Improvement in Pipe Wrenches, of which the following description, in connection with the accompany: ing drawing, is a specification, like characters on the drawing representing like parts.
This invention relates to pipe wrenches of that type comprisig a handle member having a fixed jaw at one end and a movable jaw member pivotally securedto the handle member and acted upon b a spring which tends to move it toward t e fixed jaw.
The object of my invention is to provide an improved spring for acting on the movable jaw.
The features wherein the invention resides will be more fully hereinafter set forth and then pointed out in the claims.
In order to give an understanding of the invention I have illustrated in the drawings a selected embodiment thereof which will 2 now be described after which the novel features will be pointed out in the appended claims.
Fig. 1 is a sectional view through a wrench embodying my invention, and
Fig. 2 is a section on the line 2-2 of Fig. 1.
The wrench herein illustratedis provided with the handle member 1 which is formed at one end with the fixed jaw 2, the latter indicated at 8. and it is provided with a shank 4 which is pivotally secured to the handle 1 as shown at 5. The handle member l is formed with the opening or slot 6 in which the shank 4 enters.
The pivoted jaw 3 is acted upon by a spring which tends to swing it toward the fixed aw as usual in wrenches of this type and my present invention relates to the spring device employed for this purpose. Said spring device is shown at 7 and it is in the form of a spring wire having the special shape shown. This spring wire has one end anchored to the handle member 1 as shown at 8 and the spring wire extends forwardly from the anchoring point 8 as shown at 9 and then is bent upwardly as inbeing a curved face. The movable jaw is,
dicated at 1.0 and then is bent rearwardly as shown at 11 and downwardly and forwardly as shown at 12 and then upwardly as shown at 13. The upper end of the portion 13 of the spring is pivotally secured at 14 to a rocking arm or radius member 15 that in turn is situated within the slot 6 and is pivoted to the handle portion 1, as shown at 16. This rocking arm is connected to the shank 4 of the pivoted jaw 3 by means of a link 17.
The tension of the spring 7 acting through the swinging member 15 and link 17 tends to move the pivoted jaw 3 forwardly toward the fixed jaw. In using the device the jaw 3 is forced backwardly into the dotted line position so that the pipe or rod to be turned may be entered between the jaws and when this is done the tension of the spring brings the pivoted jaw 3 forwardly into grlpplng engagement with the pipe or rod and holds it in such position. When force is applied to the handle member 1 in the direction of the arrow the grip on the pipe will be increased sulficiently to turn the pipe. A swinging movement of the handle in the direction opposite to that of the arrow will release the gripping pressure on the pipe and enable the wrench to be removed.
One advantage of this construction is that the swinging member 15, link 17 and the spring is confined within the slot 6 and is, therefore, protected by the walls of the slot.
The construction has the further advantags that it affords a spring of considerable effective length and one which will allow of a wide range of movement of the pivoted jaw but which can be confined within a relatively small space.
I claim.
1. In a pipe wrench, the combination with a handle member having a fixed jaw at one end, of a movable jaw pivoted to the handle member, a link pivoted to the movable jaw between its pivotal point and the jaw portion thereof, a pivotally mounted radius member connected to the link, and a spring acting on the radius member and tending through the latter and link to swing the pivoted jaw toward the fixed jaw.
2. In a pipe wrench, the combination with a handle having a fixed jaw at one end, of
a movable jaw pivoted to the handle memher, an arm pivoted at one end to said handle member, a link connectin the other end of said arm to the pivoted 32mg, and a spring member connected at one end to said arm and extending downwardly from said arm, then backwardly and upwardly and forwardly and then downwardly again, the end of a spring being secnred to the handle member. 10 In testimony whereof, I have signed my name to this specification.
WILLIAM A. ELLISON.
