each and every steam pipe which can be
opened into the atmosphere for heating purposes. For leading steam
joints, mix the red lead or litharge with common commercial glycerine,
instead of linseed oil. Put a little carbolic acid in your glue or
paste pot. It will keep the contents sweet for a long time. Look well
to the bearings of your shafting engine and machines. Sometimes 25,
30, 40 and even 50 per cent. of your power is consumed through lack of
good oil. When you buy a water wheel, be sure to buy one small enough
to run at full gate while the stream is low during the summer months.
If you want more power than the small wheel will give, then put in two
or more wheels of various sizes. When it becomes necessary to trim a
piece of rubber, it will be found that the knife will cut much more
readily if dipped in water. When forging a chisel or other cutting
tool, never upset the end of the tool. If necessary cut it off,
but don't try to force it back into a good cutting edge. In tubular
boilers the handholes should be often opened, and all collections
removed from over the fire. When boilers are fed in front, and are
blown off through the same pipe, the collection of mud or sediment in
the rear end should be often removed. Nearly all smoke may be consumed
without special apparatus, by attending with a little common sense to
a few simple rules. Suppose we have a battery of boilers, and "soft
coal" is the fuel. Go to the first boiler, shut the damper nearly up,
and fire up one-half of the furnace, close the door, open damper, and
go to the next boiler and repeat the firing. By this method nearly,
if not quite, all the smoke will be consumed. A coiled spring inserted
between engine and machinery is highly beneficial where extreme
regularity of power is required. It is well known that a steam engine,
in order to govern itself, must run too fast and too slow in order
to close or open its valves; hence an irregularity of power is
unavoidable.
