Improvements in Steam and other Fluid Pressure Engines.
I, HENRY EMMETT GAMBLE, of 41, Beek Straat, Hoboken, Belgium, Mechanical
Engineer, do hereby declare the nature of this invention to be as follows:-
Among the objects sought to be attained by the use of this invention are the
reduction of vibration over that usually found in reciprocating engines, simplicity
of construction, and economy in working.
The nature of the invention may be broadly stated as consisting in causing the
pressure in the cylinder to produce at the same time motion in both directions,
the parts being so coupled or connected that the motion of either of the parts
tends to produce an opposite movement of the other part.
The invention may be carried out by mounting the engine cylinder on trun-
nions eccentrically placed with reference to the rotatable discs which carry it.
The piston or connecting rod is similarly mounted on a second disc which is in
gear however with that or those carrying the cylinder.
With this construction motion of the piston causes the disc carrying the piston
rod to rotate in one direction and that motion alone would cause the disc carrying
the cylinder to rotate in the other, but this end is also assured by the pressure
between the cylinder end and piston which tends to rotate the cylinder carrying
dise in one direction and through the gear the piston carrying disc in the other.
In this manner an equilization of forces is attained and an engine more per-
fectly balanced and more free from vibration than usual is secured.
In lieu of the discs connecting rods or cranks may be employed, while the
steam or other inlet and exhaust ports and pipes for the cylinder may be either
located in the trunnions or the connection may be made by flexible pipes or slid-
ing connections.

the following statement:-
Among the objects sought to be attained by the use of this invention are the
reduction of vibration over that usually found in reciprocating engines, simplicity
of construction, and economy in working.
The nature of the invention may be broadly stated as consisting in causing the
pressure in the cylinder to produce at the same time motion in both directions,
the parts being so coupled or connected that the motion of either of the parts
tends to produce an opposite movement of the other part.
The invention may be carried out by mounting the engine cylinder on trun-
nions eccentrically placed with reference to the rotatable discs which carry it.
The piston or connecting rod, is similarly mounted on a second disc which is in
gear however with that or those carrying the cylinder.
With this construction motion of the piston causes the disc carrying the piston
rod to rotate in one direction and that motion alone would cause the disc carrying
the cylinder to rotate in the other, but this end is also assured by the pressure
between the cylinder end and piston which tends to rotate the cylinder carrying
disc in one direction and through the gear the piston carrying disc in the other.
In this manner an equilization of forces is attained and an engine more per-
fectly balanced and more free from vibration than usual is secured.
In lieu of the discs connecting rods or cranks may be employed, while the
steam or other inlet and exhaust ports and pipes for the cylinder may be either
located in the trunnions or the connection may be made by flexible pipes or slid-
ing connections.
In order that the invention may be clearly understood reference is made to the
accompanying drawings which illustrate one form of apparatus made in accord-
ance with this invention, and in which
Fig. 1 is an elevation partly in section.
Fig. 2 a plan view of same, and
Fig. 3 a cross section on line 1 1 of Fig. 1.
As shown in the drawings the steam cylinder A is mounted on a trunnion or
bearing B eccentrically placed with respect to the carrying gear wheel C which
in turn is carried in suitable bearings D. Steam or other propulsive force passes
through pipe F and trunnion B to what is here represented as an ordinary steam
chest G provided with the usual inlet and exhaust ports and valve, the latter
being represented as operated from a fixed heart shaped cam H in which travels
the roller end of the valve rod I. The piston rod J is eccentrically mounted with
relation to gear K which meshes with gear C.
With this arrangement of parts it will be evident that the pressure on the
piston will not only cause movement of the piston rod in one direction but also
a corresponding movement of the cylinder in the opposite, and that owing to the
movement of these parts being regulated and connected by the gears there will
be no loss of power and less vibration will be produced than in ordinary recipro-
cating engines.
It will be evident that in lieu of steam, gas or other fluid pressure may be
employed, and also that cranks or other forms of connecting gear may be substi-
tuted for the gear wheels shown and that various forms of valves and means for
operating same may be devised.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is―
1st. In steam and other fluid pressure engines causing the pressure in the
cylinder to produce at the same time rotary motion in both directions the parts
being so coupled or connected that the motion of either of the parts tends to pro-
duce an opposite rotary movement of the other part.

page_text: 2nd. In steam and other fluid pressure engines the combination of a pressure
cylinder mounted eccentrically with reference to the disc or shaft which carries
it, a piston or connecting rod similarly mounted on a second disc or shaft, and
means for connecting and regulating the motion of the two discs or shafts, sub-
stantially as described.
3rd. The improved steam or other fluid pressure engine, substantially as here-
inbefore described.
