This model 92 Jacobs Rubberflex collet chuck’s support base has a threaded center mount, very much like optical instruments. There is a large ring on the top of the base to tighten the base down, and the base has a rubber gasket around its periphery. It also has a carrying case with handle, so it was designed to be a portable instrument, or perhaps it was to be used as a cover when not in use. It doesn’t show up in the Jacobs spindle chuck catalog Jacobs Manufacturing Co. - Publication Reprints - Jacobs Collet Chucks | VintageMachinery.org, but after disassembly it is the model 92 with the flat back.
So I am surmising that it was designed for use as a mount for optical tooling. Can anyone confirm or if you have other theories, share?
I bought it thinking it would make a good outboard support for long bar stock for the 10EE, if used with a good tripod.
