SPECIFICATION forming part of Letters Patent No. 663,564, dated December 11, 1900- Application filed June 9, 1900- b'erial No. 19,733. (No model.)
To ctZZ whom it may concern.-
Be it known that I, EVEN H. EVENSON, a citizen of the United States, residing at New Richland, in the county of VVaseca and State of Minnesota, have invented new and useful Improvements in Wrenches, of which the following is a specification.
My invention relates to monkey-wrenches, the object being to provide a simple and inexpensive device of this character which may be easily manipulated and firmly held in any position to which it is adjusted.
The construction of the improvement will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification.
In the drawings, Figure l is a view in perspective of a wrench embodying the invention, and Fig. 2 is a longitudinal section of the same.
The reference-numeral l designates the shank of the wrench, and 2 a jaw formed integral therewith. The shank is formed adjacent to the jaw 2 with a longitudinal slot 3 extending well toward the center of the shank, and below said slot 3 is another longitudinalslot I, open at its lower end and having one of its walls 5 inclined, as shown in Fig. 2.
6 designates a hollow casing having a jaw 7 formed integral with its upper end and open at its back and upper end to receive the shank 1, which is connected with the casing by means of a screw or pin 8, extending through openings in the casing and through the slot '3 in the shank.
The inner surface of the front wall of the casing 6 is formed for a part of its length with a series of ratchet-teeth 9, which coact with a series of teeth 10 on the shank 1, which are inclined in a direction opposite to that of the teeth on the casing 6.
constructed as thus described will be readily understood.
The spring 11 holds the teeth of the shank in engagement with those of the casing 6, permitting the casing and lower jaw to be moved freely upward. To effect a reverse movement of the jaw 7, the shank l is tilted upon the pin 8 by pressing against the back of the jaw 2, thus disengaging the teeth 9 and 10 and forcing the spring 11 backward.
I claim l. A wrench comprising a shank formed with two longitudinal slots one below the other and with inclined teeth; a jaw fixed to the upper end of the shank; a hollow casing formed with a jaw and with internal teeth coacting with the teeth on the shoulder; a cross-pin connecting the shank and casing; and a spring secured to the casing and extend- 'ing into the lower slot of the shank.
2. A wrench comprising a shank formed with two longitudinal slots arranged one above the other, and with inclined teeth; a jaw formed integral with the shank; a hollow casing having a jaw formed integral therewith and formed with teeth inclined in a direction opposite to that of the inclination of the teeth on the shank; and a spring secured at one end to the casing and having its free end bearing against the shank.
In testimony whereof I aflix my signature in presence of two witnesses.
EVEN H. EVENSON.
