Drill Press Vice - Who Made it?

[RHJO51]

I posted this over in the Vise thread but no responses - I must have stumped the experts... I came across a interesting drill press vise I've never seen before. It's brass tagged "The Producto Machine Co" Bridgeport ct. It has a unusual design - there is only about 3/4" movement of the screw handle, you push the dynamic jaw, then insert the lever into one the groves, then tighten the handle. It's a 3" jaw, body is 8 1/2". Marked 101 with no other markings. I don't know if was made by Producto or owned and brass tagged by Producto. Anyone have any info on this one?

I would say it was made by Producto. They made small production type machine tools where the operator does the same operation over and over loading and machining simple parts. Ed.

+1 on Ed's reply.

Hey at least they're still an existing company look at Moore Precision Machine Tool, they own Producto (and yes its still a Diamond logo), they might be able to give you additional information?

Looking at the vise
It would appear to me that Larry or at Producto made it on first shift.
But that’s just the gut feeling I am getting

So it's a unique design for a quick set vise. I'm guessing the large grooved shaft slides freely through the back of the vise near the crank. This way you slide the dynamic jaw along with the outer grooved tube, inner threaded shaft and crank up to the work, lock the cam in the closest ring slot it will grab, then tighten down the crank. This means the threads are (female) inside the grooved tube and (male threads) on the shaft that runs from the crank to the dynamic jaw and you can see the end of it attached at the dynamic jaw.

Simply put, the main shaft is attached to the crank at one end and the dynamic jaw at the other. The main shaft is threaded to the inside of the grooved tube.

I've never seen this design on a quick set vise before. Very nice!
