Yesterday's Find

[Wrenchmensch]

For years I've had a G. M. Company's combination monkey wrench, tack remover, and hammer hanging on one of the wrench boards. I considered it a flawed wrench because the lower wrench jaw was not attached to the handle. Yesterday I found a second one of these. I picked it up and the jaw remained attached. There was a piece of spring metal stuck out-of-sight between the lower jaw and the handle. I bought it ($8). This afternoon I discovered the spring clips into the slot in the back of the jaw thereby stabilizing the jaw and making jaw adjustments much easier.  A real Eureka! moment.

The sawtooth rack makes it a quick adjust wrench, but without the spring is is going to be a quick unadjust wrench also.

Hmm....

I soppose if the spring can fall out, it's not so unbreakable after all LOL

Very classy wrench :)


PS: I'm almost certain that wrench is patented...

Good find! Can you now make a replacement spring for your original one?

I've been asked for spring dimensions for this wrench.

The spring dimensions are:

Thickness:   .00275 in.
Width:         .250 in.
Length OA:1.578125 in.
Length Tab: .109375 in.

Notes: the exposed end of the spring is cut in a shallow radius with its highest point .0625 in. above a straight line across the spring's width. The tab is square cut.  The spring's overall curvature and the end bends can be seen from the photos.
