cone pulley

noun

1. (on a lathe) a pulley consisting of a conelike arrangement of graduated, concentric pulleys for driving the headstock at different speeds.

Example Sentences

One method of doing this is to throw off the belt that operates the feed spindle h, place n in gear with o and p′ in contact with o, so that the transverse feed motion will be in action, and then pull by hand the cone pulley driving h, thus feeding the tool to its necessary depth of cut.

From Project Gutenberg

Work whose dimension is within the limit of capacity of the shaper can, however, be more expeditiously shaped than planed because the speed of the cutting tool can be varied to suit the nature of the work, by reason of the machine having a cone pulley, whereas in a planing machine the cutting speed of the tool is the same for all sizes of work, and all kinds of metal.

From Project Gutenberg

Motion for the cone pulley a is received by pulleys b and is conveyed by belt to cone pulley c, which is provided with back gear, as shown; the driving spindle d drives the bevel pinion e, which gears with the bevel-wheel f, which drives the drill spindle g by means of a feather fitting in a keyway or spline that runs along that spindle.

From Project Gutenberg

The cone pulley a is provided with back gear b placed beneath it, the live spindle driving the drill spindle through the bevel gears c, one of which is fast upon a sleeve d through which the drill spindle e passes.

From Project Gutenberg

The spindle of this cone pulley drives a belt which passes up the column over an idle pulley on the sliding head that carries the radial arm; hence it passes along the front of the radial arm and partly round a pulley on the drill spindle, two idle pulleys holding it in contact with the drill spindle pulley.
