A NEW MOTIVE POWER.
The Hydro Pneumatic PuIsatimg
Engine.

A correspondent of the Titusvilc Coa-
rier, writing to that paper from Phlapel-
phia, gives very interesting description
of new motor known as 1.-The Hydro
Pneumatic Pulsating Engine" The in
ventor explains, that with the best water
or turbine wheel, now in use, one hundred
pounds of water are requisite to produce
eghty-two pounds of power; but in this
machine one pound Of water is sufficient
to produce one thousand pounds of pow
er. The agents furnishing this immense
power are not new. They are as old as
creation and rs necessary to our life as
they are to furnish the motive power Of
this engine. These agents are simply air
and water in the proportion Of liftccn-sx-
teenths of the former to one-siXtccnth Of
the latter. Everything about it is patent
to the eye, except the arrangement of tho
air chambers which give the elements
propclling power, and these ARE very
properly concealed 10y copper cylinder
or receiver. A rubber hose is attached
to the cold water Stopcock of II bath-tub,
and this the water passes into and upon
what is called "diaphragm," in
stream the size Of a goosequll.
Upon the introduction of the water,
which is used only as "packer" or
lubricator," II cast iron nywhcel is set
in motion and presently revolves at the
rate of five hundred to nine hundred
revolutions minute, the spokcs of the
wheel glittaring rs solid surface. 4
head of four pounds of water through n
goosequill produces instant activity, Civ
ing n capacity of several hundred pounds,
each stroke Of the pulsating medium, and
dispensing power upon the pulley sutli-
cient to raise thirty-siX thousand pounds
one foot per minute.
In the small one-h horse machine now in
operation the cylinder in which the piston
moves is only the size of II copper cent;
yet it runs readily with great velocity,
lifting at every stroke of the pulsating
medium weight 50 arranged 10y leverage
rs to be equal to seven hundred pounds
and the strongest man finds it impossible
to affect the speed a particle by applying
friction to the cogs of n wheel six inches
in diameter, by which the power is di-
rectly applied to the machinery.
BY an Improvement utilizing the escape
of waste water, five hundred pounds Of
power per minute are gained, and tho
engine runs itself, either with pressure,
or independent Of it, The full power Of
the small machine now in operation can
be gained, by a stream running through
tube no larger than luciicr match.
The machinery is simple, and yet there
is mechanical combination 50 ingenious
ly contrived, as Civ such n multiplied
ton of powers as to .nsh all bcholders
either scientific or practical.
1t requires no fuel, no caloric, or any
chemical agent. Air and very small
stream of cold water are the only agents
used. 1t will not occupy one-tourth tho
space, nor cost half as much as an ordi-
nary steam engine OF the same power;
and economically considered, will be tho
cheapest motor ever brought into prac-
tical use. The propolling agents are alb
solutely without cost-tho only cost after
the first cost being the wear and tear OF
the machine, by friction. The inventor
says, "only keep tho water running into
it, and the machine will be kept in motion
until worn out" Active preparations
are now in progress for putting up "A ten
horse power engine.
