Canada

Acquired from Mr. A. B. Cummings of South March, Ontario. Lathes were a major component of metalworking and woodworking shops in Canada that started in the 19th century. These shops were key in advancing Canadian machine work and distancing Canada from American and British machines. These shops were also used majorly during the First and Second World Wars to mass produce machinery and storage units.

Fonction

Screw cutting lathe, contains lead screw that caused the cutting tool to advance an accurate amount that can be predetermined for each rotation of the screw. Ability to cut a variety of thread pitches. Contained new features: reverse motion and improved foot pedal.

Technique

This model came with a reverse motion design, in which the spindle and screw cutting gear are completely reversed, which runs the carriage back as the lathe goes full speed forwards. This was different from the right and left motion that was used at the time. Model also had improved foot power, which allowed ease of operation, no wasted power, and a greater operating speed obtained with less effort. Simple gearing system all cut from solid metal. Turn work 18 in long, 4.25 in diameter, and swings 8 in over the bed, which was 3 ft. Model is a cone pulley lathe (driven by flat belts run on pulleys), which are not used today (replaced by geared-head lathes). Providence screw cutting lathe.
