The correct Wright Wrench this time

[mikeswrenches]

Here's another try at the Wright Wrench.  This example is 6 in. long although I believe they were also made in larger versions.

These were a quick adjust wrench that used a very fine tooth rack on the front that mated with a corresponding rack inside on the sliding jaw.
Pushing in on the bottom portion of the moving jaw, disengages the rack and allows it to be slid either up or down.

The screw at the bottom of the rack allowed it to be removed for replacement if necessary.  Also the interior rack could also be replaced.

Patented March 15, 1904           No. 754,633

A very kewl wrench, and a nice example, with an excellent logo mark :)

I think they made pipe versions also.

Is this the same compay as the current Wright tool?

Lewill2, You are quite correct, there was a pipe wrench made.  I have one of this same general design but with a much coarser rack.  It was patented by C.E. Bonner on August 25, 1903 and is No. 737,199.  The first patent was Dec. 23, 1902  and is No. 716,515 by W.S. Bonner.  It was apparently never manufactured.  It also does not resemble the production version, although that is not unusual.

This works the same as the Wright Wrench in that you push the bottom of the moveable jaw in towards the shank in order to move the jaw up or down as required.

C.E. Bonner was a totally separate company.  ( www.datamp.org/patents/advance.php?pn=737199 ) is the Bonner pipe wrench patent.  Bonner went bust when they sunk all their capital trying to get into the automobile manufacturing business.   WRIGHT closed out their wrench line abruptly and went into the specialty drop forging business (get a contract, make the stuff & get paid -- no carrying inventory for a long time like you do if you are a tool maker ).

All these WRIGHT , BONNER, etc. patents are in DATAMP.  (use the "search for manufacturer" and "search for patentee" )
