Improvements in and relating
other Explosive Power Engines.
I ADAM MILLER of No. 205 Mansion House Chambers, No. 11 Queen Victoria
Street in the City of London, in the County of Middlesex, Engineer, do hereby declare
the nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
My Invention has for its object the so arranging of the Motor Piston, Valves and
Cylinder, that an explosion is obtained at both ends of the Cylinder, and one explosion
at every revolution; by this means I obtain more power and greater regularity in
working.
The Cylinder is made with two diameters, namely:-large and small;-the larger
diameter is made for the power piston to work in; the smaller diameter is made for
the guide of the power piston.
The Piston is made tight in both diameters by expanding rings.
I arrange the Cylinder with a clearance space at both ends of the large diameter
portion, as explosion chambers.
The cylinder is made with water jackets.
The admission and exhaust may be effected by slide valves, or the common single
seated conical valve. I use in this instance, single and double seated conical valves
for admission and exhaust. These valves are actuated by cams or tappets and
levers.
The method of igniting the compressed compound in the cylinder may be effected
with a flame from a lamp, a jet of gas or by electricity.
The manner of operation is as follows:-
During the first stroke of the piston either from the outer or inner end of the
cylinder, air gas or vapour may be drawn or sucked into the cylinder, the piston at
this time acting as the piston of a pump. On the return stroke of the piston to either
the outer or inner end of the cylinder, the compound which has been drawn in at either
end, is compressed to the volumes of the spaces made at the ends of the cylinder.
The ignition takes place at the end of the stroke immediately after the com-
pression.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved arrangement and construction of the cylinder, of the Piston and
guide.
2. The improved arrangement and action of the valves to give an explosion at each
revolution.
3. The improved construction of the double seated valves.
