easy and with great economy.
On the accompanying drawing:
Figure 1 is a view of the complete machine seen from right side of Figure 2;
Figure 2 is a side view ;
Figure 3 shows the top part of one half of the working cylinder;
Figure 4 is a vertical section of the machine ;
Figures 5 and 6 are a vertical and a horizontal section respectively of the top
part of the working cylinder;
Figures 7 and 8 show the arrangement of the governor.
Upon the framing 1 is fixed a casing 2 which consists of two rings being provided
at its inner part with semicircular grooves so that when both pieces are screwed
together, they form a hollow. annular space of circular section, the working
cyl
ylinder 3. Into this cylinder is brought the piston with ordinary packing
rings, which is driven in the following manner.
The casing 2 is provided with steam inlet and outlet pipes 5 and 6 the first of
which carries the admission valve 7. Between these pipes a closing plate 8 in the
cylinder is arranged allowing the motive force, entering at 5 to expand and drive
round the piston its prescribed circular way.
Now the closing plate 8 for the sake of giving a free passage to the piston is
provided with a circular opening 8a which is brought in the proper moment, in
contact with the working cylinder..
For this purpose the closing plate 8 is suspended in a peculiar casing 9 of the
cylinder, so that it may swing round a bolt 10; a bar 11 seizes this plate 8.and
communicates to it its alternative longitudinal motion.
When closing the cylinder the plate 8 is. tighted by means of a packing ring H
of triangular section which is put into a groove of rectangular obtuse form which
is cut into the plate 8 so that steam etc. may enter the free space of the groove and
press the packing ring against the walls of the cylinder 3. The steam after having
driven round the piston escapes through the pipe 6. The piston 4 transmits its
motion directly to the driving shaft 13 by means of a disk.15 and an arm 16. The
shaft 13 running through the middle of the casing 2 is carried in brackets 14, to
it is fixed the fly wheel 19, the boss of which is provided with a projection 20 by
means of which a lever 21 linked to the framing is made to swing. Its free end
seizes the bar 12 giving it the necessary longitudinal motion.

page_text: For preventing the steam etc. to escape, through the slot 17 provided for the
arm 16 of the piston two packing rings 18 of triangular section are fixed to the
inner circular face of the casing 2, having a spring like action so that no steam
can escape through the slot 17.
The distribution of the moving force is attained by means of a valve 23 Fig. 3
being guided in its casing 7 by a bar 7 a upon which works a cam 25 fixed to a
spindle 24.
Corresponding to the degree of rotation which is communicated to the spindle 24
the cam 2 lifts the valve more or less for the sake of governing the admission of
the steam.
For this purpose a peculiar regulating mechanism is arranged consisting of a
box 26 which is keyed to the driving shaft 13. Into suitable slots of this box are
lodged the levers 29 turning themselves with the bolts 27 and being provided with
the fly balls 28. These levers are pressed against the shaft 13 by means of a
spiral spring 30 and a box 31 pressing against projections of the levers 29.
Now the bolts 27 are fitted at its outer ends with gudgeons 32 for raising and
lowering a slide piece 33 when the fly balls are working. The slide piece 33
Figs. 2. 7 & 8. acts upon a cam 34 which is linked to the box 26 so that a vertical
bar standing upon said cam is raised and lowered. The bar 35 is connected with
the valve 23 by the spindle 24 and its cam 25 lifting it thus corresponding to the
working of the balls 28.
For getting a rapid closing of the valve its bar may be provided with a
spring 36.
The machine thus described may be built as stated in the present example
without or with condensation.
In the latter case an increased economy of power and easier working may by
obtained by a vacuum produced before the piston.
Instead of one working cylinder only there may by two ore three cylinders
arranged the pistons acting all commonly upon one shaft. When the machine
is built with reversing gear it may be preferably used for steamers and the like.
Having now particularly described the nature of my said invention and in what
manner the same is to be performed, I declare that what I claim is :-
:-
1. In rotary motors the arrangement and use of a working cylinder 3, having a
hollow annular space and a piston 4 in combination with a closing plate 8 serving
to allow the motive force to enter between said plate and the piston and drive
round the latter its circular way transmitting thus directly movement to the main
shaft 13 as described and for the purpose set forth.
2. The arrangement of an annular working cylinder 3 with piston 4 and closing
plate 8 in combination with a distributing valve 23 being lifted by a cam 25 on a
spindle 24 and pressed down by a spring 36 as described and for the purpose
set forth.
3. The arrangement of an annular working cylinder 3 in combination with a
regulating mechanism consisting of a box 26, flying levers and balls 29, 28, a slide
piece 33 being raised and lowered by the working of the balls and moving up and
down by means of a cam 34 a bar 35 linked to the valve cam spindle 24 as
described and for the purpose set forth.
