THEODORE D. cnlnsroennn 0r MADISON, INDIANA Letters Patent No. 68.168, dated August 27, 1867.
IMPROVEMENT IN WEENGHES.
ToALL WHOM IT nn -conca'nm Be it known that I, THEODORE D. CHRISTOPHER, of Madison, Jefferson county, Indiana, have invented a. new and useful Improvement in Wrenches; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make'and r se the same, reference lbeing bad to the accompanying drawings, forming part of this specification. V v
' This invention consists in combining a screw and ratchet-wrench in such a manner that whille the jaw is firmly held by a. catch-bar working in the ratchet, the jaw can be adjusted iyith the" greatest nicety' by the screw and nut; and' italso consists in the mannerin which the catch-bar is constructed and. operated.
Y FignreT'iepr-esents the wrench complete. 1
{Fig'u 'is a cross-section throhgh the line 2' :v'
Similar letters of-reference'indieate-eerrespmrding-parts; e a V A represents the wrenchrbar; B is the fast jaw, and G is'the movable or sliding jaw; D is a sliding hand "or thimhle which is moved back and forth over the bar; E is a plate attachedto thethimble D; F is the catchbar, which is hinged to the plate E, as seen in fig. 2, the end of which is acted on by a spring, a, which serves to keep the catch-in place; G is a screw which is attached to the slidingjaw C; H is a nut which works on the screw, and which is attached by a pin to the plate E; ,on which pin it revolves. The operation will be readily understood from the drawing.
When the jaw O and the'thimbie D are drawn back over the ratchet-teeth the catch-bar F is turned out of the ratchet,'as seen in the drawing When the jaw is in abouts-the right position the catch-bar is closed down and into the ratchet, engaging with one of the teeth, anditis held in place by the spring a. "If, when in this posit-ion, the jaws C and B do not fit the nut to be turned suflici ently well, the nnt'H is turned on the screw G,
so-that the jaws-may coine inclose contact with'the not. In ordinary. casesthe jaws of the wrench can be adjusted with suflicient accuracy hy the ratchet-teeth and catch-bar alone.
What I claim as new, and desire to securekhy Letters Patent,'isn 1. The coxhbination of the sliding thimble D, the plate E, the catch-bar F, and the spring a with a ratchetnrench, substantially as and for the purposes set forth.
I claim the same, in comhination with the screw G and nut H; arranged substantially as shown and described, on bar e'of a rjschet-wrench, for the purposes set forth.
THEODORE D. CHRISTOPHER.
