I bought a box of stuff at auction - specifically for the B&S tooling
it contained. Well I ended up with several other tool holders.
I've never seen any holders with the mounting style they have. Have
you? Here is a picture of a typical holder. It holds tools that have a
morse #2 taper.
Looks like some sort of Quick Switch tooling. A Hurco conversational
CNC I use (it doesn't have an ATC) uses one that looks almost
identical but the two pegs that stick out are flat, not round. You
stick the toolholder into the spindle and give it a 1/4 turn with a
special spanner, then tighten a nut down maybe 1 turn or less to hold
it in place. About 10 seconds for the switch if you're fast.
I'm glad somebody else uses B&S tooling. My old US Machine Tool
vertical mill has a B&S #9 spindle, so I am always looking, too.
Your request reminds me of a story that they tell at the Wisconsin
state historical site of an early 20th century commercial fishing
company on the south shore of lake Superior. It was run by two
brothers. When one died, and (IIRC the surviving brother passed the
place on to the state. Anyway, the state has to document EVERY thing on
the site and the "things" are identified with a 6 digit number painted
In the workshop, under the workbenches, were several piles and
several buckets of metal objects that the curators couldn't identify.
Finally, they gave up on a lot of it and went to ask the surviving
brother to help.
He simply said "Gee, I don't have any idea. If my brother ever saw
a piece of metal along side the road, he would pick it up and drag it
home to the workshop in case we ever needed something of that shape!"
