Chapter CVIII: Section 23: Conveying Motion to Movable Parts of Machinery

(_See also p. 62._)

=2038. Jointed tube= for a travelling, hydraulic, steam, or compressed air, hoisting, or other engine.

=2039. A travelling wheel= may be driven by a long pinion without affecting the travelling movement of the wheel.

=2040. Travelling spur gear= similar to last, to convey continuous motion to a travelling machine.

=Hydraulic transfer.= Two rotary motors (hydraulic) are used, one as
driver, the other as motor, and connected together by two pipes
forming the suction and delivery pipes, by which a continuous
circulation is kept up, and the motor driven by the driver, the latter
being driven from a shaft or engine. The pipes may be taken a great
distance, if made large enough.
