[2021]. Balanced cutter head for a milling or moulding machine.
Section 21.—CIRCULAR AND RECIPROCATING MOTION.
(See also [p. 56].)
[2022]. The “Dake” square piston engine; has a reciprocating double piston and a transverse sliding block, by which rotary motion is communicated to the crank pin.
[2023]. Chapman’s patent crank motion. In this gear the cylinders are fixed at right angles and their strokes are four times the radius of the crank, which is coupled by a link with equal arms (of the same radius as the crank) to the two crossheads direct.
[2024]. Crank motion. The crank pin runs in a sleeve having a sliding motion along the lever.
[2025]. Crank motion (in plan), with side connecting rod and off guide. The crank shaft crosses the piston rod as near as may be.
[2026]. Crank motion, with semi-yoke crosshead.
[2027]. Crank motion, with yoke connecting rod.
