Garvin Screw Machine. The smallest in the range and a lathe dedicated solely to the production of small parts, not greater than 0.25" in diameter, such as the screws studs and pins as found in watch cases, clocks, electric-light fittings and instruments, etc.

Garvin made screw machines in a variety of  sizes and to special order.  Their No. 2 and No. 12 machines were heavily built - over 1100 lbs - and designed to handle general screw and stud work and "ordinary machine-shop use".

The largest Garvin Screw Machine was the No. 3, a powerful lathe that weighed over one ton. Power was fed to the turret slide by gears and a chain-driven rod - enabling it to be driven along the bed.

A rare survivor. A No.1 Garvin hand-screw lathe. As small capstan lathes are awkward to use for regular work, when worn out this class of machine was usually weighed in for scrap.
