J. M. MARTIN PIPE WRENCH 2 sheets-sheet 2 Filed Feb. 1, 1922' Patented Apr. 3, 1923.
JAMES M. MARTIN, OF KNOXVILLE, TENNESSEE.
PIPE WRENCH.
Application filed February 1, 1922. Serial No. 533,347.
T all whom it may concern:
Be it known that I, JAMES M. MARTIN, a
citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Pipe WVrenclnof which the following is a specification.
This invention relates to tools and more particularly to novel form of wrench especially designed for use in operating on pipes or other cylindrical objects.
The primary object of the invention is to provide a wrench having means whereby the outer or movable jaw thereof may be adjusted with accuracy to insure the jaws closely gripping the article under operation.
Another object of the invention is to provide a wrench which will be exceptionally strong and durable, and one wherein the movable jaw will be guided through its support.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawings: Figure 1 is a side elevational view of a wrench constructed in accordance with the present invention.
Figure 2 is a rear elevational view thereof.
Figure 3 is a sectional view taken on line 33 of Figure 1.
Figure 4 is a sectional view taken on line 44 of Figure 1.
Figure 5 is a detail view of the guiding members forming a part of the movable jaw supporting member.
Figure 6 is a fragmental sectional view through a portion of the frame.
Referring to the drawings in detail, the reference character 5 designates the handle portion of the wrench which is provided with an enlargement 6 at the inner end thereof, which enlargement is formed with teeth 7 providing one jaw of the wrench.
The frame of the wrench is indicated at 8 and is formed with an integral yoke 9 which embraces a portion of the handle of the wrench, adjacent to the jaw 6 thereof,
to permit the frame to move with respect to the handle, it being understood that the yoke is relatively long as compared with the width of the handle to allow for such movement. As shown, the frame 8 has pivotal connection with the handleof the wrench as at 10.
The frame is formed with an opening throughout the length thereof, which accommodates the threaded shank 11 of the movable jaw, the movable jaw being indicated at 12 and formed at the outer end of the shank 11 as clearly shown by Figure 1 of the drawings. Formed in opposite sides of the threaded shank 11 are key ways 13 that accommodate the integral keys 14 formed on the frame, through the body portion to insure a true operation of the wrench. The side walls of the frame 8 are cut away to provide clearances for the adjusting sleeve 15, which is formed with internal threads cooperating with the threads of the shank 11 so that when the sleeve is rotated, the shank 11 will be fed through the frame 8 to move the outer jaw 12 with respect to the inner or stationary jaw 6.
As shown, the handle 5 is formed with a shoulder 24 providing an abutment for one edge of the sleeve 15, and relieve the threads of the shank 11 of the strain usually direeted thereto, when the wrench is put into use. In order that the frame 8 will be held in alignment with the side walls of the handle, spring arms 16 and 18 are provided, the spring arm 16 having one end thereof secured to the handle 8 as at 17 the opposite end thereof lying within the yoke 9 to exert a pressure thereon. The spring arm 18 has one end secured to the handle as at 19, the opposite end of the arm 18 underlying a portion of the frame 8 to equalize the pressure of the arm 16. In the form of the invention as illustrated byFigure 5 of the drawings, the keys 20 are secured to the frame portion 22 as by means of the screws 21 which are shown as passing through suitable threaded openings in the keys. Thus it will be seen that due to this construction, if the keys 20 become worn or otherwise rendered inoperative, the keys may be readily removed and replaced.
At one end of the handle 5, is a hook member 23 which provides a stop for the operators hands in the event that the operator is which keys guide the shank 11 I using the wrench high over his head, and the operator should lose his grip on the article under operation to cause his hands to slip over the wrench.
From the foregoing it will be obvious that when the jaw 12 has been adjusted with respect to the jaw 7 to closely engage an artiele, the handle 5 may be pivoted with respect to the movable jaw and body 8 to release its grip on the article to permit the wrench to be moved with respect to the article so that the wrench may again be moved to accomplish its purpose.
Having thus described the invention, what is claimed as new is 1. In a wrench, a handle, a aw formed at one end of the handle, a pivoted frame supported by the handle, a jaw movable through the frame, said jaw including a threaded shank, said shank having key-ways formed in opposite sides thereof, a sleeve having threads cooperating with the threads of the shank to move the movable jaw, keys supported by the frame, and disposed in the key-ways, portions thereof being embraced by the sleeve, and resilient means for normally holding the frame in its active position.
2. In a wrench, a handle, a aw formed at one end of the handle, a pivoted frame supported by the handle, a threaded sleeve supported by the frame, a movable j aw including a threaded shank movable through the sleeve, said shank having key-ways formed in opposite sides thereof, keys positioned in the key 'vays, bloeks secured to the keys and disposed on opposte sides of the sleeveto hold th sleeve against movement longitudinally of the keys, and resilient means for normally holding the frame in its active position.
In testimony that I claim the foregoing as my own, I have hereto affixed my signa ture in the presence of two witnesses.
