Pokorney ratchets
« on: July 06, 2014, 02:56:05 PM »
Found this 2 together, the smaller one has been well used. With the different lettering I believe the larger is the newer of the two. I noticed at the bottom of the Datamp page it has, Demuth Steel Products Co., are supposed to be some of the markings on them but I didn't see it.
And, the larger one has a # 1 on it for 1".

Strange.

Metal Devices shows up in the mid 1920's, Pokorney in the mid 1940's-50's.

Metal devices was at least a tool maker, but they were sold at public auction around 1927

Pokorney made mostly air compressor things...

Edit: Hmm, well, these 2 companiees have a relationship after all

United States. Board of Tax Appeals - ‎1945
"In 1926 a deal was made with B. W. Pokorney Company, purusant to which the
 Pokorney Company changed its name to Metal Devices Corporation, took over
  the assets of the C. J. Sykes Manufacturing Company, and paid for them with
 stock ... "

B W  Pokorney is also listed elsewhere under grey/cast metal foundries....

Sykes was also a tool maker

1922:The C. J. Sykes Mfg. Co., manufacturer of talking machine parts, automobile
accessories, dies, tools, etc., 2132 Lawrence Avenue, Chicago, has purchased
the southwest corner of Maplewood and Shubert Streets

1925:Metal Devices Co. his bought from the C. J. Sykes Mfg. Co. the
factory building at Maplewood and Schubert

(guess the new factory thing didn't last long ;P)

(The tax case says there were 2 partnerships and 3 corporations involved in the rename/aquisition/merger, another was Pratt Automatic Machine Co, I dunno who the other partnership was)
Pratt made the Automobile locks for D&M Auto Lock Co , for keeping people from stealing your 1920 Buick...

Just a weathered light rust/WD40 mix patina.

The Wright patent # 1,089,737 is a mechanically simple, rugged ratchet that appears to have been supplied as the wrench for tightening the bands on wood stave silos & tanks, as well as the ratchet in  (by today's standard) crude looking socket sets.
It was never clear to me whether  the markings represented successive  manufacturer's names, or the names of companies that used the wrench.  Any kind of print documentation (ads, flyers, etc.) would really be helpful.

The underground pipe wrenches we buy today look exactly like those.

HeelSpur, thanks for that link.  Fascinating stuff I'd only heard about, though I've repaired remote wooden drinking-water tanks up on stilts — drill out (to round a hole) a small leak, add bolt with leather scraps backed by metal washers.  Hadn't heard about wooden plugs but they make sense too.
