Improvements in Rotary Engines.
1, JOHANN BURGERMEISTER of Hogyesz, Hungary, Clock Maker, 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:-
This invention relates to a rotary engine in which the steam or other pressure
fluid acts directly upon a vane secured to the driving shaft.
Four different constructions of the rotary engine are shown on the accom-
panying sheets of drawings.
Figs. 1 2 and 3 show respectively in vertical section, cross section, and in plan
one form of the engine.
Figs. 4 and 5 show.details of the construction.
Fig. 6 is a longitudinal section and Fig. 7 a cross section of a modification.
Figs. 8 and 9-show another modification whilst Figs. 10 and 11 show respectively
in side view and section yet another modification.
The working of the engine shown in Figs. 1 to 5 is as follows:-
The semi-circular block a for controlling the steam supply, by alternately, as it
revolves, covering over or exposing the port e, is secured to the disc b which is
keyed to and rotates with the shaft c. This disc may have teeth on its periphery,
as at Fig. 5, if it is desired to transmit power. Steam is admitted by the pipe d
and passes through the port e into the cylinder h (see also Fig. 4) where it acts
directly upon the vane fof the shaft c, and, as a consequence, causes both to rotate
in the direction of the arrow. As soon as, in its rotation, the vane passes the
exhaust port g the steam escapes through said port into the atmosphere.
The flywheel u has an elliptical part p by which the slide valve m is operated.
As the momentum of the fly wheel maintains the rotation of the shaft after the
steam has escaped through the exhaust port g, it follows that the vane f continues
its rotation, and, further, the parts are so arranged, that, when the vane approaches
the valve m the latter is lifted up out of the way by the elliptical part of the
fly wheel acting on the upper exposed part m' of said valve. This part m as will
be seen, Fig. 1, has friction rollers m2 between which the flange of the fly wheel
passes. The continued revolution of the fly wheel eventually, as will readily
be understood, forces the slide valve m back again until it bears tight against
the shaft c.
As a result of the continued rotation of the shaft c the port e is again uncovered
by the block a and steam gains access to the cylinder h and gives a fresh impulse
to the vanef until it is cut off the second time by the continued revolution of said
block a.
The action before described continues so long as steam is supplied to the
engine.
To cause the shaft e to rotate in a reverse direction the outlet and inlet ports d
and g must be correspondingly reversed.
In the arrangement shown at Figs. 6 and 7 the valve m is raised at the proper
times by means of a cam-like projection k fixed to the shaft c and to the back of
the vanef. The valve is caused to fall again by means of a spring, as shown, or
by gravity. The steam enters at d and escapes at i. The supply of steam is
controlled in the same way as before.

page_text: In the arrangement shown at Figs. 8 and 9 the only difference is in the
distribution of the steam. The steam which enters the hollow fixed central
shaft cat passes there-through and enters the cylinder h through the port y
where it acts upon the vane fand slide valve and imparts a rotary movement to
the cylinder and the fly. wheel secured thereto. As soon as the cylinder has
turned sufficiently far for the arm fixed to the shaft to begin raising the slide valve
the steam will enter through the opening o of the sleeve and finally escape
through the opening ' into the shaft c' and from thence by the outlet yl to the
atmosphere.
The fourth arrangement, Figs. 10 and 11, is suitable for engines having no fly
wheel such as ship's engines for instance. In this case the steam enters through
the ports d and e into the cylinder and imparts a rotation to the shaft c and
vane, in the direction indicated by the arrow, until the cam shaped projection z¹,
fixed to the shaft, slightly raises the slide valve m whereupon the steam forces up
the valve until it uncovers the exhaust port through which the steam escapes.
The vanefis so arranged as to release the slide valve, after the escape of the
steam, whereupon it will fall by its own gravity or under the action of a spring to
its original position. A reverse rotation cau be produced in this case by merely
reversing the inlet and outlet ports.
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
consider novel and desire to claim is :-
1. A rotary engine in which the steam enters the cylinder through an inlet
port e; whenever it is uncovered by the block a, and acts upon the vane secured
to the shaft c in such manner as to cause the shaft to rotate, and finally escapes
through the outlet g, substantially as hereinbefore described with reference to
the drawings annexed.
2. The modification of the invention wherein an elliptical extension is made
on the fly wheel for the purpose of actuating the slide valve, substantially as
hereinbefore described and shown on the drawings annexed.
3. The modification of the invention wherein a cam shaped projection k secured
to the vane is used for actuating the slide valve, substantially as hereinbefore
described with reference to the drawings annexed.
4. The modification of the invention wherein steam is admitted to the cylinder
through the hollow shaft c', substantially as herein before described with reference
to Figs. 8 and 9 of the drawings annexed.
5. The modification of the invention wherein a cam shaped projection z' is used
to raise the valve m, substantially as hereinbefore described with reference to
Figs. 10 and 11 of the drawings annexed.

Improvements in and connected with Gas Irons.
I, GEORGE EDWARD BERRY, Laundry Engineer, of Shrub End, Colchester,
in the County of Essex, 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 :-
This invention relates to gas heated laundry irons and has for its object the
production of a gas heated iron in which the products of combustion are led away
and not allowed to escape into the surrounding atmosphere.
I will particularly describe my invention making reference to the accompanying
sheet of drawings in which :-
Figure 1 is a view in side elevation of my improved gas iron.
Figure 2 is a view in longitudinal section thereof.
Figure 3 is a view in transverse section on line ax of Figure 1.
Figure 4 is a view in front elevation of the air and gas and exhaust pipes, and
Figure 5 is a view in plan thereof in section.
Throughout the views similar parts are marked with like letters of reference.
The body or main casing A of the iron is provided with a cover B and a
burner plate C, thus dividing the interior of the iron into two distinct parts or
chambers, the top one A being the air and gas chamber and the bottom one A
the combustion chamber; the cover B and burner plate C being secured to the
nain casing A by means of screws bb. The burner plate C is provided with
numerous holes or burners c c which are supplied with a combustible mixture of
air and gas by means of the pipe D. In the interior of the iron along the bottom
of the main casing is provided a groove or channel a which is covered by a
baffle plate E provided with suitable perforations e to allow the products of
combustion to be withdrawn from the interior of the iron by means of the pipe F.
In the main casing, is provided one or more ventilation holes a¹ which com-
municate with the combustion chamber A. To allow of inspection of the
interior of the iron whilst in use a spy hole as is provided in the casing A, and
is preferably covered with a disc of mica or the like. The cover B carries the
usual handle X.
F is the main gas pipe which supplies an auxiliary pipe F¹ which is furnished
with a cock or tap f, the gas on entering the mixing chamber G draws in a
certain amount of atmospheric air through a hole g, the amount of air being
regulated by means of a coned screw g¹ or an equivalent device; the mixture of
air and gas is then led by means of a suitable flexible tube to the pipe D of the
chamber A'; it is then burnt in the combustion chamber A' and the products of
combustion drawn away from the iron by means of a fan or other exhausting device
situated in a tube or pipe H communicating with a chimney or the like, the tube
or pipe H is in communication with a pipe h which is connected to the pipe F by
means of suitable flexible tubing.
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 :-
The improvements in and relating to gas heated irons, substantially as herein-
before described and illustrated by the accompanying drawing.
