Are they called block chucks on a lathe??
On lathes, I hear them referred to as "noses" or "closers" (snap handle or
spin).
At least in my semi-exhaustive hunt for a used lathe w/collet closer!

The one I have is simply a holder for the collets that fits a Jarno
taper [0.60"/ft].
I am machining an adaptor to fit my 1-1/2" 8 TPI headstock.
