Complete Specification Left, 3rd Aug.. 1892-Accepted, 3rd Sept., 1892
PROVISIONAL SPECIFICATION.
Improvements in Steam and other Engines suitable also for use
as Pumps.
I, AUGUST RIEDINGER of the firm of The Kommanditgesellschaft für
Druckluftanlagen August Riedinger & Co. of Augsburg in the Empire of Germany
do hereby declare the nature of my invention to be as follows :-
The improved engine adapted to be driven by steam or any other suitable gas or
vapour under pressure comprises a closed chamber enclosing the crank shaft
pitman and excentric mechanism and carrying a single acting vertical cylinder.
The cover of this chamber which cover forms also the cylinder head carries the
inlet and outlet, each of these being a puppet valve, the inlet or admission valve
opening outwards from the cylinder and the outlet or exhaust valve opening
inwards towards the cylinder. Each of these valves is separately controlled by an
arm on a rod guided vertically, one on each side of the cylinder and moved each
by a separate excentric on the main shaft.
By removing the valve governing connections the motor may be converted into
a compressor or pump the inlet valve becoming the pressure valve and the exhaust
valve the suction valve.
Dated this 28th day of December 1891.

COMPLETE SPECIFICATION.
Improvements in Steam and other Engines suitable also for use
as Pumps.
I AUGUST RIEDINGER of the firm of The Kommanditgesellschaft für
Druckluftanlagen August Riedinger & Co. of Augsburg in the Empire of Germany
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:-
The improved engine adapted to be driven by steam or any other suitable gas
or vapour under pressure comprises a closed chamber, enclosing the crank shaft,
pitman and eccentric mechanism and carrying a single acting vertical cylinder.
The cover of this chamber, which cover forms also the cylinder head carries the
inlet and outlet valves each of these being a puppet valve, the inlet or admission
valve opening outwards from the cylinder and the outlet or exhaust valve opening
inwards towards the cylinder. Each of these valves is separately controlled by an
arm on a rod guided vertically, one on each side of the cylinder and moved each
by a separate eccentric on the main shaft. These arms are not fixed with the
valve spindles but are free to move out of contact with the latter during portions
of the stroke. To operate the inlet valve the arm is provided with a rider moving
on an inclined plane and governed in position by the speed regulator. The effect
of the rider is to cause the valve to be opened sooner or later according to the
speed.
By removing the valve governing connections the motor may be converted into a
compressor or pump, the inlet valve becoming the pressure valve and the exhaust
valve the suction valve.
In the annexed drawing
Figs. 1 and 2 are vertical sections of the motor on planes at right angles the
one to the other

page_text: Fig. 3 is a cross section on the line of the main shaft.
Fig. 4 is a cross section on the plane of the cylinder head.
Gis the casing, C the cylinder, D the cover thereof, E the inlet valve A the
outlet valve S' S the rods carrying the arms H' H2 which operate the valves.
M the rider on the arm H¹.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
A motor in which the inlet and outlet valves whose axes are parallel with the
axis of the cylinder are kept closed by weights, springs or air pressure and operated
by rods S¹ S³ with arms H³ H² substantially as described.
