Check if your machine name is listed under Jones in the link included above.
Also try

For example this online statement:
The easiest way to confirm if your badged machine is a Jones C.S. is to look for the large screw head on top of the arm between the two spool pins.
On search for my machine,
patent date matches the imprint on the bobbin cover plate too.
Hope this helps you
