WILLIAM EDWARD GEDGE, of N° 11, Wellington Street, Strand, London, in the
County of Middlesex, Patent Agent, "IMPROVEMENTS IN ROTARY GAS ENGINES"
A Communication to me from abroad by Fritz Marti and Julius Quaglio, of Paris,
France.
This invention relates to a Gas Engine based in principle upon the inner
mechanical combinations of the rotary suction Apparatus, or Extractor, of
"Beale's" system, well known in the manufacture of Gas.
In "Beale's" system, motion is communicated by any kind of motive power, and.
the working of the blades or pallets, dividing the interior into compartments, as for
object to produce a vacuum with suction on one side and to drive out with pressure
on the other.
In the method the subject of this invention the working is reversed, it is by
first producing the vacuum and then the pressure in the said compartments that the
continuous rotary motion is obtained, and that it may be transmitted to the exterior
in the same manner as with ordinary motive Power Generators.
This Invention may be defined as the application as a gas motor, of a rotary
machine with inner eccentric cylinder carrying blades or pallets, and in which are
utilized as motive power, the pressure produced by the combination of a mixture
of air and gas, and the vacuum resulting from the contraction of these products of
combustion suitably cooled, whether pressure and vacuum be used conjointly or
separately.
According to the dimensions of the machine and the power to be obtained, the
cylinder may be provided with a greater or lesser number of blades, or pallets, so
as to divide the cylinder into two, four, six or more compartments.
.So long as in the rotary motion the compartments become larger, they fill with
air, or with an explosive mixture of air and gas; Then, when these compartments
begin to decrease in capacity, the products of combustion of the mixture of air and
gas which they enclose contract, and become condensed by means of an exterior
cooling, or an injection, or condensing jet, of cold water,

page_text: In the cylinder casing is made an orifice through which enters the air or the
explosive mixture of air and gas, also one by which the introduction of gas alone,
or of the lighted mixture of air and gas, takes place, also small openings intended
to admit the injection water, led thereto by a pipe and with or without pressure
There is also an orifice in the outer casing by which escape the products of
combustion and the injected water, which are received in a reservoir.
In certain positions occupied by the blades or pallets the mixture of air and gas
burns without pressure, the motor working by the effect of the vacuum only. The
movement of the piston continuing, the blades begin to decrease tho capacity of the
compartment containing the products of combustion. There is then contraction
and condensation of these products and consequently a rotary movement communi-
cated to the axle of the piston, which it can transmit.
