LOUIS SIMON, of the Firm Louis Simon and Son, of Wilford Road Works,
Nottingham, in the County of Nottingham, Printing Machine and Gas Engine
Manufacturers "IMPROVEMENTS IN THE CONSTRUCTION OF ENGINES TO BE WORKED
BY POWER DERIVED FROM AIR AND OIL COMBINED."
This Invention relates to improvements in the construction of engines to be
worked by power derived from air and oil combined, and consists mainly in so con-
structing engines that the whole of the working parts are in connection with the
main shaft, by or from which other machines can be driven.
The engine according to my Invention is self-contained, that is to say, it com-
presses atmospheric air and pumps oil, such as petroleum from a reservoir, the two
into
being then combined in suitable proportions in a chamber and caused to pass
a cylinder, where they are exploded for the devolpment of power by expansion, and
made to act upon a piston in the ordinary way of steam for the movement of the
various parts.
Upon a foundation or bed composed of one or more compressed air reservoirs,
and in some cases a water trough, I mount standards for carrying a crank shaft,
one crank of which has attached a piston rod of the air compressing cylinder, and
another crank the piston rod of the power giving cylinder. The air compression
cylinder is provided with valves, and has a bye pass to permit the air to pass into
one of the reservoirs, from which the other of the two reservoirs receives its
charge, to be afterwards shut off for the air in it to be held in reserve if desired.
The power cylinder is enclosed in a water jacket, whose chamber is kept supplied
by a small pump worked by the main shaft, the water being taken from and
returned to the trough forming part of the foundation, or in any other convenient
manner.
The upper part of the power cylinder has a branch through which the air and
oil combined are forced into the cylinder upon the piston by a pump, a cut off
valve being also fitted in the branch to prevent back flow. The oil is forced into
the chamber by a separate pump also worked direct by the main shaft, and the air
11

a suitably weighted valve to limit the pressure of the compressed air. There is a
branch pipo attached to the column and provided with a double kind of valvo, that
when the hand wheel is turned, say, an eighth of a circle, just sufficient air is
permitted to pass to charge the oil at first starting, the further turn of the hand t
wheel admitting the full charge of air for continuing the working of the engine.
The induction valve, which is also the cut off of the power cylinder branch, is
controlled by a cam on the main shaft, and a bowl is free to ride up and down the
cam by the action of a governor through a bell crank, the governor being rotated
by bevil gearing on the main shaft.
The power cylinder which is open at the bottom is provided with an exhaust
branch at the opposite side to the induction branch, and is provided with a shut off
valve, also actuated by the main shaft through a cam thereon.
