UNITED STATES PATENT OFFICE.
EDWARD J. BOURNE, OF SPOKANE, WASHINGTON.
WRENCH.
To all whom t may concern:
Be it known that I, EDWARD J. BOURNE, a citizen of the United States, residing at Spokane, in the county of Spokane, State of lvashington, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in t-he art to which it appertains to make and use the same.
This invention relates to improvements in wrenches, and has particular reference t-o the type of pivoted handle shanks.
The principal object of the invention is to provide a simple device of this character, by means of which the movable jaw may be quickly adjusted, and held in adjusted position, without danger of displacement.
Another object is to provide means on the pivoted handle for cooperation with a similar means on the movable jaw for holding the movable j aw securely in its adjusted posit-ion while the wrench is in operation.
In the drawings z-Figure 1 is a side elevation of a wrench made in accordance with my invention, Fig. 2 is a front elevation of the same, Fig. 3 is a vertical section on the line 3-3 of Fig. 2.
Referring particularly to the drawings, 10 represents the head of the wrench, having the outer aw 11, and the bifurcated portion 12. Between the outer ends of the bifurcation 12 is pivoted one end of the handle 13, the pivotal end of which is cut away to form a reduced extension 14 for engagement with the stop pin 15 extending across the bifurcation. In one edge face of the handle 13 is formed a series of teeth 16 for cooperation with the movable jaw which will be referred to later.
Formed integral-ly with each portion of the bifurcation 12 and on one edge is the outwardly extending portion 17, the upper edges 18 of which lie in the same plane, and are nearly parallel with the serrated face 19 of the outer jaw 11.
Slidably mounted through these portions 17 is a movable jaw 20, the upper face of which is serrated as indicated at 21. The
Specification of Letters Patent.
Application filed February 21, 1912.
Patented July 30, 1912. Serial No. 679,155.
upper portion of the inner edge of the movable jaw 20 is straight as indicated at 22, while the lower po-rtion inclines downwardly and outwardly, and is formed with a series of teeth 23 similar to the teeth 16 on the handle 13, and for coperation therewith in a manner to be described later. The movable jaw 20 is formedvwith two approximately parallel diagonally arranged slots 241- thro-ugh which pass the pins 25 which are arranged across the bifurcation 12. By means of these slots and pins the jaw may be moved upwardly and downwardly toward and away from the outer jaw 11, a slight lateral movement being obtained during this movement.
In the operation of the wrench, when it is desired to rotate a pipe, the pipe is disposed between the aws 11 and 20, the handle 13 is moved toward the outer jaw 11. The jaw 20 is advanced until its serrated face 21 engages the pipe, whereupon the handle 13 is swung on its pivot until the teeth 16 engage with the teeth 23, which hold the jaw 2O in its adjusted position. Pressure on the handle 13 will hold the jaw 20 securely against the pipe, which may be easily turned. To release the jaw 20, it is only necessary to swing the handle 13 backwardly on its pivot until the extension 14 engages the stop pin 15, when the jaw 2O will be readily moved toward or away from the jaw 11.
What is claimed is 1. A pipe wrench comprising a head having an outer jaw portion and a bifurcated portion, a handle pivoted within the bifurcated portion, a series of teeth formed on one edge face of the handle, a movable jaw disposed within the bifurcation, said jaw having a series of teeth on one end, for engagement with the teeth of the handle, said movable j aw having a plurality of obliquely arranged and nearly parallel slots, and guide pins extending across the bifurcation and through the slots.
2. A pipe wrench comprising a bifurcated head, a handle pivoted between the bifurcations of the head, teeth on the handle, a jaw slidably mounted between the bifurcations, means for guiding the jaw, an outer jaw on the bifui'eated head,the adjusting movement In testimony whereof, I aliX my signao the movable Jaw 1n one direction being ture, in presence of two Witnesses. simultaneously toward the outer ]aW and the fr i shank, and longitudinally of the shank, and ED" ARD J' BOURB E' means on the movable jaw for engagement Witnesses: by the teeth of the handle, to hold the jaw in C. E. HoR'ioN, adjusted position. C. M. MOE.
Coliies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. Washington, D. C.
