MONKEY WRENCH. APPLIGATION FILED $313.15 1905 INVENTOR ATTORNEY UNITED STATES Patented. June 6, 1905.
PATENT OFFIC MONKEY-WRENCH.
SPECIFICATION forming part of Letters Patent No. 791,809, dated J une 6, 1905.
Application filed February 15, 1905. Serial No. 245,799-
To all whom it may concern:
Be it known that I, THEODOR OLSON, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and usefulImprovements in Quick-Acting Monkey-Wrenches, of which the following is a specification. v
This invention relates to certain new and useful improvements in pipe-wrenches, and has for its object to construct a wrench of this character that will be easy to operate, strong, durable, and practically inexpensive to manufacture.
An advantage of this invention resides in the fact that no chain or spring is used in combination with the jaws, which is a common construction of the ones now in commercial use; but the several points are so constructed that it will be impossible for the same to become inoperative.
Reference will be had to the accompanying drawings, forming part of this specification, in which similar figures of reference indicate corresponding parts in both of the drawings.
Figure 1 is a side View of my improved pipewrench and showing in dotted lines the jaws closed. Fig. 2 is an edge view of Fig. 1.
Referring to the drawings, 3 is the handle of the wrench, having formed integral therewith forked members 4, and pivotally mounted therein, near the base of the fork on bolt 5, is a tongue 6, formed on the upper jaw 7. The movable jaw 8 loosely moves upon the tongue 6 and is held firmly against the object by pulling upon the handle in the direction of the arrow, and in this illustration I have shown a pipe 9to be removed from a nipple 10; but the same can be used for various purposes. The pressure on the lower jaw is brought to bear where the upper portion of the forked members 4 come in contact with the inclined surface 11 of the movable jaw, and the gripping-faces of the jaws are serrated to firmly grasp the object and prevent slipping. To obtain a reverse movement from that shown in the drawings, position the jaws on the opposite side of the fork 4 and exert pressure on the handle in the opposite direction to the arrow. Replacing the upper jaw 7 by others having tongues of various lengths will give more or less space between the jaws, as the occasion may require, and enable one to grip objects of different diameters. This is a feature of great advantage, as one tool of my construction will take the place of a set of the ones now in use.
Having described my invention, what I claim, andwish to secure by Letters Patent, 1s-
In a pipe-wrench, the combination with a handle having a forked end, a tongue pivotally mounted at one end within the forked end near the base of said fork, a jaw carried by the opposite end of the tongue and a movable jaw, slidably mounted on the tongue, said movable jaw having its sides inclined and adapted to be engaged by the free portions of the fork.
' In testimony whereof I aflix my signature, in the presence of two witnesses, this 14th day of February, 1905.
- THEODOR OLSON.
