"BECHER" wrench

[stanley62]

I found this one at an Old Tool Swap meet this morning.  I can find a Carl Becher with a wrench patent, but it doesn't look like this critter.
Marker "BECHER" on one side, D.R.P 105813 on the other.  I am guessing German made???

 My German stinks, but my Google translate says:
"Wrench with led in the handle and the lower jaw upper jaw
Submitted on January 20, 1898; Issue of patent
on 22 September 1899. We have already described this construction, cf previous year of this journal, p 400"

>We have already described this construction,...

That would explain why there was no picture :(

Sadly, I don't have the previous year :(

I found it elsewhere tho...

The blob of text seems to describe how the jaw works without breaking...

The interesting word is the last one tho, "aufzuheben", which translaes to "repealed"
Perhaps this wasn't a novel idea after all...

Roughly:

Wrench with the handle and the lower surface of upper jaw guided.

M has the upper jaw at the rear end of the extension s, which is guided in the back surface of the lower jaw. With this extension, the force exerted on the cheek m force is transmitted to the jaw m ', such that it counteracts the force exerted on this jaw force. The purpose is to reduce the effect of the forces on the dangerous section bezw"

Thanks Rusty!  On the Pegboard it goes.

 If the pegboard is full I might have an opening in my basement. Nice find.
