AN AERo.HYDRAuLIc MOTOR.
An English Device, Said to Be a
Great Saver of Power.

The greatest discovery of the pres
ent age, says the London Iron and
Steel Journal may be described as the
proved fact that force, like matter, is
indestructible, and that it is in the
application Of force in its different
forms that invention has found its
evident field of operation. Therefore,
cation force and the full utilization of
every possible atom of energy must
lead to more satisfactory result for
the same expenditure of power than
is possible when a greater or less pro-
portion of the force generated is al.
lowed to run to waste.
1t is with this object of avoiding
any such leakage of power that Mr..
Corvisier's patent aero-hydraulic mo-
tor engine has engrossed the skill and
Inventive capabilities Of the patentee
for period extending over the last
70 years, and as a result he has been
able to produce a motor, which, with
out the aid of fire, steam or electri-
city, will accomplish just the saving
of energy and full utilization of power
which has long been the desideratum
of those who understand the intrica-
cies of machinery.
In the ordinary hydraulic press the
small piston travels a relatively long
distance, while the large piston only
moves short distnace. If, therefore,
by suitable arrangement of the nee
essary parts the large piston can be
driven through distance practically
equal to that of the small piston with
out the necessity of increasing its
initial force, it is evident that an ac-
cumulator will be obtained giving a
very considerable gain in force and
speed. This is what has been ac-
complished by the invention above
referred to. Ii secures a great advan-
tage in economy, and is applicable to
the production of any kind of work.
In steam engine the displacement
of the piston necessitates the filing
up at every stroke of an empty space,
while in hydraulic press the volume
of displacement of the large piston
must be filled with an equivalent vol
ume of water. 1t is, therefore, clear
that if the piston of a steam engine
or of a hydraulic press could be dis
placed without the need of filling up
the space created by the displace-
men, the gain would be considerable.
This highly desirable end is obtained
in Corvisfer's patent by the employ
ment of piston of special construc-
ltion, of construction entirely differ
ent from that OF any known piston,
the piston not being made of metal,
but of a pliable and deformal mater
of rubber, strengthened with layers
or backings of canvas, so as to adapt
it to withstand q high strain. Any
material will serve the purpose, al
ways provided it possesses the COM
bined qualities Of pliability and re-
sistancy, and is capable Of changing
it's form and returning to it again, ac-
cording to the work effected. 1t is
said that the new motor will soon be
ready to be placed on the British mar
ket. The possibilities of it's useful
ness are stupendous, and it's general
adoption cannot fail to result in an
immense saving to manufacturers in
every one of the many important in
dustries to which it can be applied.
The invention claims that it is cap
able of performing a twelve hours
continuous work on a consumption Of
$50 gallons of water. Every engin-
eer will be able to judge what saw
ing is meant by this. The aero-hy-
draulic motor bids fair to supersede
the use of steam power in a great
number of cases. thus doing away
with combustion and smoky CHM
