The practical draughtsman's book of industrial design, and machinist's and engineer's drawing companion: forming a complete course of mechanical, engineering, and architectural drawing . other slide traverses the cosine, A b. To apply this practically,any two of the slides, actuated by G, h, and I, are connected bythe proportionate wheels, whilst the third gives the cutting mo- tion in the remaining direction of the cube. To reverse theangle, a subsidiary wheel is introduced into the pair of change-wheels. In many cases a crankmovement is convenient,in addition to the guide-screw planing move-ment, to work shortstrokes with rapidity;while the guide-screwserves for longer ranges,and also to adjust theslide-rest. The crankdisc is then driven by abevil pinion on the shaft,a, the connecting-rodbeing attached to oneof the bearings of theguide-screw, which ismade to slide similarlyto the barrelling move-ment. Fig. 5 represents a composite lathe, or shaping machine, con-structed on the model of the ordinary planing machine, anddesigned for accurately finishing thepieces forming the framings of marineand other engines at one setting, but alsoapplicable to a variety of other w
