I picked up an antique cable puller today at the flea market. While this is not a "Bell System" tool, per se, in terms of markings, Western Electric was a division of Bell and operated as its equipment supplier. The marking is worn. I've included a naked close-up and a chalked close-up, but you really need a magnifying glass to read it. It's marked BUFFALO GRIP NO. 1, in a circle, and FROM / WESTERN ELECTRIC CO. / NEW YORK CHICAGO / PAT'D APR. 25, 1893 / CANADA 1898.
All of the examples I have seen on-line of this tool are newer, with the same model number (No. 1) or an even newer "No. 2", all a Nov. 29, 1910 US patent date, and a Canada 1911 patent date.
I'm stumped on the patent number itself. I can't find it anywhere on-line (DATAMP, Justia, Google Patents, etc) using the date. That is a valid patent date, but I haven't located the actual patent yet.
EDIT: Also, does anyone know anything about the "X"? What does it signify? (It almost looks like the crossed cannons of the Ordnance Dept.)
