Description
A. HYDE.
(No Model.)
WRENCH.
Patented Oct. 9, 1883.
/ UNITED STATES PATENT Grinch.
ANDREW HYDE, OF HATFIELD, MASSACHUSETTS.
WRENCH.
SPECIFICATION formingpart of Letters Patent No. 286,543, dated October 9, 1883.
Application filed March 29, 1883. (N model.)
To all "whom it may concern:
Be it known that I, ANDREW HYDE, a citizen of the United States, residing at Hatfield,
and of which the monkey-wrench is a type;
and it consists in the combination, with the thumb-nut and an adjacent fixed point, of a spring-detent arranged to engage with the roughened outer surface of the nut to hold it, and having an arm adapted to be moved by the finger rotating the nut in either direction to free the nut, the object of the invention being to prevent the exact adjustment of the jaws from being accidentally changed, while permitting their manipulation by the usual movement of the thumb of the hand grasping the wrench.
In the drawings, Figure I is aplan view of a wrench having my improvement. Fig. 11 is aside view of the same, and Fig. 111 is a section on the line a: 0:, Figs. I and II.
Bis the handle. D is the inner jaw. G is the screw. H is the thumb-nut, and I is the bar. As shown, the nut H, having the usual milled perimeter, has the annular channel h formed therein.
Beneath the nut H and recessed in the bar I is the s'pringdetent m, hinged at n, and prolonged into the curved arm and thumb-piece d. The piece (I is arranged to be in the path of the thumb pressing upon the nut H to rotate it, and, having a smooth surface, offers no obstacle to the movement of the thumb, which, in rotating the nut in either. direction, depresses the arm (E into channel h and passes over it, thereby swinging the detent m clear from the milled nut-surface, and holding it in that position. When the required adjustment of the jaws is obtained, the removal of the thumb from the nut H brings the detent in into operation to prevent any j ar or accidental contact of the thumb-nut with any object from changing the position of the jaws of thewrench.
In practice I prefer to arrange the springd'etent, as shown, to engage with the milled perimeter of the thumb-nut and to have the arm (I work in the channel 71, whose walls guide the part (2 in its swing, though, with out departing from the spirit of my invention, the arm d can be made to work upon one side of the nut and the. spring-detent to en- Tgage with teeth or corrugations upon the side of the thumb-nut.
What I claim is The within described improvement in wrenches, consisting of the combination, with a j aw-operating thumb-nut, of a spring-detent adapted to'engage with a roughened surface of said nut, and provided with a thumb-piece adapted to be depressed by the rotating finger to disengage said detent, all substantially as set forth.
Witnesses: ANDREW HYDE.
