Generally referred to as “dental lathes”, foot treadle polishers were
manufactured by Chicago/ Grout Koelsior. Similar machines were also marketed to jewelers and
other craftsmen. Two taper screws allow a variety of cleaning and polishing devises. A
cloth buffing wheel is mounted on the taper screw as one illustration. The spindle bearings
are provided with oil holes. The flywheel
pulley is 17 1/2″ diameter and a second drive pulley is 1 1/2″ diameter. The lathe head is mounted on a 11 1/2″ x 21″ wood table with two drawers. The machine
is 44″ high, allowing comfortable use while standing or sitting on a
high stool. The single “heel and toe” treadle works very well. Another
neat machine for the non- electric shop. My father used this machine in 1947 to polish/ clean clock parts and jewelry before he bought his electric cleaning machine. The unit needs a replacement belt (which is a piece of leather with the ends stapled together). We have baling twine on it now and it works great! Included in the accessories are containers of pumice, rouge, and troply.
