Ill IN wi/bvmm womumq.v WASHINGTON a c UNITED STATES PATENT OFFICE.
JOHN IV. LIND, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO JOHN J. MORRIS, OF SAME PLACE.
WRENCH.
I SPECIFICATION forming part of Letters Patent No. 590,619, dated September 28 1897.
Application filed May 21, 1897. Serial No. 63 7,571. (No model.)
To all whom it may concern:
Be it known that I,JOHN \V.LIND,Of Boston, (Roxbury,) in the county of Suffolk and State of Massachusetts, 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 the art to which it appertains to make and use the same.
This invention relates to improvements in wrenches; and the object of the same is to provide a simple wrench which is quickly and readily adjusted, the same being extremely simple in construction and effective in operation, as will appear hereinafter.
The invention consists in the novel features of construction hereinafter fully described, claimed, and illustrated by the accompanying drawings, in which-- Figure 1 is a side elevation with one arm of the bifurcation of the spring broken away, andFig. 2 is an edge View.
Referring to the accompanying drawings, 1 indicates the handle or shank of the stationary jaw, which is enlarged at its upper end and formed with a lateral offset 2 to form the jaw 3. Formed on the inner edge of this handle is a series of notches or teeth 4, and the longitudinally-extending slots 5 are provided adjacent its upper and lower ends.
6 indicates the movable jaws,'having the stem or handle 7, and 8 represents screws or pins which are secured to said shank or handle and move within the slots of'the stationary jaw, said pins or screws being headed to prevent their disengagement from said slots.
Secured at one end to the movable jaw is the spring 9, which is provided with a halftwist adjacent its upper end, so that a fiat surface is presented for securing the same to the jaw and extends downwardly and has its lower end bent inwardly, as illustrated. This lower end is bifurcated to extend on each side of the shank of the stationary jaw.
To adjust the wrench to suit the object upon which it is to. be positioned, the movable jaw is moved upon the stationary jaw until it bears against the object, and when the hand of the operator is compressed it causes the spring to engage the teeth of the shank of the stationary jaw and hold the jaws the desired distance apart. As soon as the spring is released it disengages from the teeth, so that the movable jaw is normally free to move upon the stationary jaw. It will be noticed that these two jaws and shank portions are formed of fiat metal bars, the entire thickness being in the present instance but three-sixteenths of an inch, thus adapting the wrench for use upon bicycles or other machinery where a Very thin wrench is desired, although, of course, I do not limit myself to its size, as the same may bevaried as desired.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The combination of a stationary jaw having its. shank formed with slots, a movable jaw .having pins projecting therefrom which are adapted to move within said slots, the stationary jaw formed with a series of teeth upon its edge, and a spring-rod secured at one end to the movable jaw and adapted to engage the teeth by the contraction of the hand of the operator, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
JOHN W. LIND.
