A shover arm E, which passes through acast-iron guide on the side of the trough opposite the deck, is attachedto each triangle.

The device is operated by a foot pedal or by a lever arm which,by means of the necessary rod connections, controls the two-wayvalve on the cylinder F. The log kicker is controlled by the deck man,who, by the use of the foot pedal or lever, admits steam into the baseof the cylinder F, thus actuating the lever arms and forcing the logout of the trough and upon the deck. This type is best adapted forlogs of average length. A mill having two log decks has a separate log kicker equipmentfor each. Mills having two head-saws are usually equipped to cut 1 The size of the cylinders varies from 10 by 30 inches to 18 by 42 inches, depend-ing on the amount of work to be performed.

A type of log kicker designed for rolling logs both ways out of thelog slide is shown in Fig. 26. The main cylinder A is oscillating, beingtilted either to the right or to the left by the small stationary cylinderB. When the cylinder A is tilted to the right, logs are thrown to theleft, and vice versa. The valves of both cylinders are controlled by
