_A._–To find how much before the end of the stroke the eduction passage
will be closed:–to the lap on the steam side add the lead, and divide the
sum by half the stroke of the valve; find the arc whose sine is equal to
the quotient, and add 90 to it.; divide the lap on the eduction side by
half the stroke of the valve, and find the arc whose cosine is equal to the
quotient; subtract this arc from the one last obtained, and find the cosine
of the remainder; subtract this cosine from 2, and multiply the remainder
by half the stroke of the piston; the product is the distance of the piston
from the end of the stroke when the eduction passage is closed.

airship is eminently adapted for long distance journeys
involving non-stop flights
“For commercial purposes,” General Sykes has remarked, “the
airship is eminently adapted for long distance journeys
involving non-stop flights. It has this inherent advantage over
the aeroplane, that while there appears to be a limit to the
range of the aeroplane as at present constructed, there is
practically no limit whatever to that of the airship, as this
can be overcome by merely increasing the size. It thus appears
that for such journeys as crossing the Atlantic, or crossing the
Pacific from the west coast of America to Australia or Japan,
the airship will be peculiarly suitable. It having been
conceded that the scope of the airship is long distance travel,
the only type which need be considered for this purpose is the
rigid. The rigid airship is still in an embryonic state, but
sufficient has already been accomplished in this country, and
more particularly in Germany, to show that with increased
capacity there is no reason why, within a few years” time,
airships should not be built capable of completing the circuit
of the globe and of conveying sufficient passengers and
merchandise to render such an undertaking a paying proposition.”

_A._–The boiler and engine are hung upon a framework set on wheels, and,
together with this frame or carriage, constitute what is commonly called
the locomotive. Behind the locomotive runs another carriage, called the
tender, for holding coke and water. A common mode of connecting the engine
and tender is by means of a rigid bar, with an eye at each end through
which pins are passed. Between the engine and tender, however, buffers
should always be interposed, as their pressure contributes greatly to
prevent oscillation and other irregular motions of the engine.

508. _Q._–As the question of the locomotive boiler has been already
disposed of in discussing the question of boilers in general, it now only
remains to inquire into the subject of the engine, and we may commence with
the cylinders. Will you state the arrangement and construction of the
cylinders of a locomotive and their connections?

In England Lilienthal”s work was carried on by Percy Sinclair
Pilcher, who, born in 1866, completed six years” service in the
British Navy by the time that he was nineteen, and then went
through a course of engineering, subsequently joining Maxim in
his experimental work. It was not until 1895 that he began
to build the first of the series of gliders with which he earned
his plane among the pioneers of flight. Probably the best
account of Pilcher”s work is that given in the Aeronautical
Classics issued by the Royal Aeronautical Society, from which
the following account of Pilcher”s work is mainly abstracted.[*]

A. If properly fitted they should be keyed brass to brass; if not so
fitted, they should be keyed on the large part of the pin so they will
be free enough to run without heating and snug enough to run without
pounding. Do not key them so tight at either end as to prevent the
lateral motion of the brass on the pins.

other threshermen throughout the world, read some good ‘Threshermen”s
Home journal
And if you want to keep yourself posted as to what is being done by
other threshermen throughout the world, read some good ‘Threshermen”s
Home journal.’ The American Thresherman for instance is the ‘warmest
baby in the bunch.’ And if anything new under the sun comes out you will
find it in the pages of this bright and newsy journal. Keep to the
front in your business. Your business is as much a business as any other
profession, and while it may not be quite as remunerative as a R. R.
attorney, or the president of a life insurance company it is just as
honorable, and a good engineer is appreciated by his employer just as
much as a good man in any other business. A good engineer can not only
always have a job, but he can select his work. That is if there is any
choice of engines in a neighborhood the best man gets it.

A. Because for a given amount of water evaporated you can increase the
volume of steam 33 per cent. by superheating. It is readily seen that
the coal does not have to be burned if the steam used has 33 per cent.
more volume for filling space, or in other words, only so much steam can
be admitted to the cylinders for every movement of the valve, and what
can not be used must remain in the boiler, so if the engine can not use
all of the steam that the boiler is capable of generating, the saving
must show in coal and water. If you can not use all of the steam you do
not have to burn coal to make it.

They started by carefully surveying the work of previous
experimenters, such as Lilienthal and Chanute, and from the
lesson of some of the failures of these pioneers evolved certain
new principles which were embodied in their first glider, built
in 1900. In the first place, instead of relying upon the
shifting of the operator”s body to obtain balance, which had
proved too slow to be reliable, they fitted in front of the main
supporting surfaces what we now call an “elevator,” which could
be flexed, to control the longitudinal balance, from where the
operator lay prone upon the main supporting surfaces. The second
main innovation which they incorporated in this first glider, and
the principle of which is still used in every aeroplane in
existence, was the attainment of lateral balance by warping the
extremities of the main planes. The effect of warping or pulling
down the extremity of the wing on one side was to increase its
lift and so cause that side to rise. In the first two gliders
this control was also used for steering to right and left. Both
these methods of control were novel for other than model work, as
previous experimenters, such as Lilienthal and Pilcher, had
relied entirely upon moving the legs or shifting the position of
the body to control the longitudinal and lateral motions of their
gliders. For the main supporting surfaces of the glider the
biplane system of Chanute”s gliders was adopted with certain
modifications, while the curve of the wings was founded upon the
calculations of Lilienthal as to wind pressure and consequent
lift of the plane.
