Rotherham , —Inventors, Designers, and Manufacturers.
Improved screw-cutting lathe, exhibited for simplicityof construction and economy in working. The improve-ments consist in woi'king the saddle, and throwing outthe back gear of the fast headstock. The saddle isworked thus: the nut is solid with a spur wheel cast uponit, working into another spur wheel on a back shaft, onwhich there is a bevelled pinion; the latter works into abevelled wheel, and is keyed on an upright shaft workingthrough the saddle; there is another bevelled wheel,keyed upon the top of that shaft, working into a bevelledpinion upon the handle-shaft, which moves the saddlebackward and forward at pleasure; in addition to this,there is an index disc upon the handle-shaft, which dividesthe screws into as many threads as are required, withoutinterfering with the change wheels. The bevelled wheels
on the saddle communicate motion to the screw in thesaddle, which acts of itself transversely. The improve-ments in the fast headstock consist in a worm and wheelfor throwing out the back gear.
