air-pipe

The engine (John Jameson, engineer, Newcastle-on-Tyne, 1866), a good article, in prime condition as far as a literally rotten boiler would allow, presently revenged itself by splitting the air-pipe of the condenser from top to bottom; and after two useless halts the captain reported to me that we must return to

To get the air into both ends of the tube alternately, and to use its pressure on each side of the pellet, we will suppose that the air-pipe is forked, and that one end of each fork is inserted into the side of the tube near the end, like the figure below, and imagine also that you have put a finger over each end of the tube.

Two pulls on the life-line, and two pulls on the air-pipe, given quickly one after the other, mean that he is in trouble, and wants the help of another diver.

He is careful not to approach the wreck too suddenly, as the tangled rigging and splinters might twist or break the air-pipe and signal line; when his feet touch the bottom, he looks behind, before, and above him before he advances an inch.

To make it move we must do something more, and open one end of the tube, and close that fork of the air-pipe, and thus get all the pressure on one side of the pellet.

It was while resting at the air-pipe that these men, James Sedgwick and John

The diver can breathe while under water by means of an air-pipe, and by pulling on a life-line, can make his wants known to those above.
