Old Hand Threader

[Willard’s Welding]

Found this hand threader.
“Cowell Threader”
“PAT 1910”

“MFG FINE TOOLS”
“CHICAGO”

Can anybody tell me anything about it, especially period during which it may have been manufactured.
Thanks

Patent expiry was 17 years, so no more than 1910-27.

Lots of info here

Hello there @Willard's Welding and welcome to the site!

keep this link handy

and this one too!

Images showing the other side - or whichever surface has that information stamped on it - would most likely be of help.

Maybe we can dig something up....

@RTM - there's one posted here on Worthpoint but the only notation on the specimen is "Patent 1910" - no date.

possibly John W. Cowell (Lewald "Grasp-it") ?

Scott-Rose Company, Marquette Building, Chicago, Illinois (claimed as "maker")(?)

nomenclature might be the speed bump: "die plate" might be the correct term:

Die-plate: Scott-Rose Co., Marquette Building, Chicago, 111.
Die-plate covering a range of sizes from 3/16 to 3/4 inch.
The hardened steel removable die blocks are fitted in parallel
jaws. The distance between these jaws can be varied by a
calibrated ratchet wheel which, through the medium of a
cam. adjusts the ja'- s by small variations. This die-plate Is
15 inches long overall, and it is furnished with U. S. standard
threads unless otherwise specified.

Not in DATAMP, Internet down, so working on my phone.

1005604 was issued to one John W. Cowell, but he's in Los Angeles and the patent wasn't issued until 1911. it does look somewhat like the OP's device, though.
earlier version, maybe?

-Interesting piece, never seen one before in any shop I worked in or any tool catalog I've perused. Nice find.

That patent is the only Cowell in that category.
