A correspondent Of the Titusville Cour
Ter, writing to that paper from Philadel
phla, gives very interesting description
Of new motor known as "The IIidro
Pneumatic Pulsating Engine" The inven
tor explains that, with the best water OF
turbine wheel, now in use, one hundred
pounds of water are required to produce
eighty-two pounds of power; but in thi.
machine one pound of water is sufficient t,
produce one thousand pounds of power
The agents furnishing this immense power
arc not new. They are as old as creation
and us necessary to your life as they are t,
furnish the motive power engine. These
agents are simply air and water in the
proportions of filteen-sixteenths of the
former to one sixteenth of the latter
Everything about it is patent to the eye
except the arrangement Of the air chambers
which give the elements propelling power
and these are very properly concealed by
a copper cylinder or receiver. A rubber
hose is attached to the cold water stop cock
of bath-tub, and this the water passes
into and upon what is called a diaphragm,
in stream the size of goosequil.


Upon the introduction of water, which
is used only as a packer" or" lubrcator, y
cast-ron fly wheel is set in motion and
presently revolvcs at the rate of five hun
to nine hundred revolutions minute, the
spokes of the wheel glttcring as solid
surface. A head of four pounds Of water
through a goosequil produces instant ac-
tivity, giving capacity Of several hund-
red pounds, each stroke of the puisation
medium. and dispensing power upon the
pulley sufficient to raise thirty-six thou
sand pounds one foot per minute.


In the small one horse machine now in
operation the cylinder in which the piston
moves is the only the size of a copper
cent yet it runs readily with great veloc-
ity. lifting at every stroke of the pulsating
medium weight so arranged by the lev
erage as to be equal to about seven
hundred pounds and the strongest man
finds it impossible to affect the speed a
particle by applying friction to the cogs
of wheel six inches in diameter, by which
the power is directly applied to the ma
chinery.

Of the warer, five hundred pounds of power
per minute are gained, and the engine
runs itself either with pressure or indie
pendent of it. The full power of the
small machine now in operation can be
gained, by stream running through a
tube no larger than lucifer match. The
machinery is simple, and yet there is me-
chanical combination ingenously contriv-
ed, and giving such multiplication of
power As to astonish all beholders either
scientific or practical.


1t requires no fuel, no caloric, or chem
ical agent. Air and a very small stream
of cold water are the only agents used. 1t
will not occupy one-fourth the space, no
cost half as much as an ordinary stream
engine of the same power aud cconomi.
cally considered, it will be the cheapest
motor ever brought into practical use
The propelling agents are absolutely with.
ou. cost-the only cost being the wear
and tear of the machine by friction. The
inventor says, "onl y deep the water run
ming into it and the machine will be kept
in motion until worn out" Active meas
ures are now in progress for putting up
ten horse power engine.
