COMPLETE SPECIFICATION.
Improvements in Rotary Engines.
I, CHARLES WIES of Faulkton in the County of Faulk and State of South
Dakota United States of America Mechanical 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:-
This invention relates to certain improvements in rotary engines, and the
invention consists in certain novel features of construction and in combinations
of parts more fully described hereinafter and particularly pointed out in the
claims.
Figures 1, and 2, are sectional views showing the parts in different positions.
Figure 3, is a central longitudinal section.
Figures 4, to 15, are views of detail parts.
a, indicates the base or pedestal formed to be rigidly secured with a top concave
seat having opposite upwardly extending perforated flanges. This pedestal has the
chamber b, into which the live steam pipe discharges provided with the two separate
live steam induction ports c. d, d, indicate two separate exhaust ports.
e, indicates the horizontal engine shaft having the two separate concentric rigid
disks, each provided with a radially projecting piston head g. The two piston
heads 9, project from diametrically opposite sides of the shaft and disks. Disks f,
and piston heads g, revolve and snugly fit in two separate chambers or cylinders
separated by the plate 1, through which the shaft passes forming a central bearing
for the same and resting on the pedestal between and separating the two pairs of
induction and exhaust ports c, d.
i, i, are the two heads at the outer ends of the disks f, having stuffing boxes for
the shaft.
jj, are the rings or cylinders enclosing the spaces between the heads and plate h.
The heads and central plate and cylinders are all perforated so that the bolts k, can
rigidly clamp the parts of the engine together, whereby they can be separately
made and quickly and easily built or separated. The shaft has means for
transmitting power, and a fly wheel.
The inner sides of the two heads and the opposite sides of the central plate h, are
provided with annular grooves 1, in which bevelled steel packing rings m, are inserted
to bear against the inner faces of the disks f, and form a steam tight joint and take
up all wear, and these packing rings are pressed against disks f, by means of the
springs n, inserted in said grooves, notches o, being provided into which the ends of
the springs fit. The piston heads have edge and end recesses to receive the movable
steel packing blocks q, pressed outwardly against the interior faces of the cylinders
by springs.
The cylinders fit in the pedestal to form a steam tight joint and are securely
bolted thereto.
The portion of the engine shaft between the heads is enlarged and tapered in the
stuffing boxes so that when the screw caps r, are tightened they force in the tapered
packing rings s, and thereby take up all wear and tightly embrace the shaft.
Each cylinder is provided with separate induction and exhaust ports c', d', to
register with its respective pair of induction and exhaust ports in the pedestal.
Each cylinder at the inner end of its induction port is recessed at t. The inner end
of recess t, is provided with bearing u, to receive the rounded edge v, of the
swinging abutment to, which is so formed as to snugly fit in said recess t, and allow
the passage of the piston head, and close the induction port, and as soon as the
piston head has passed to be forced up by the steam pressure into the position
shown in Figure 1, tightly closing the interior of the cylinder so that the steam
[Price 6d1

page_text: pressure is exerted on the piston head. The rounded edge of the rocking abutment
has the end journals which are mounted in the central plate and cylinder heads.
When each piston head has made a complete revolution it strikes the abutment and
forces, it down into the recess to allow passage of the piston head and at the same
time allowing steam to exhaust through passage d. As the two piston heads in two
separate cylinders are oppositely arranged there is no dead center, as the live steam'
is constantly exerting its pressure on one of the pistons to rotate the engine shaft.
When one piston head is passing its abutment the other is receiving the full force
of the steam.
The piston heads snugly fit their cylinders and the swinging abutments have
packing, see dotted lines Figure 11, similar to the piston head packing.
What I claim is :-
1st. The herein described rotary engine, substantially as set forth.
2nd. In combination, a pedestal having the two pairs of induction and exhaust
ports, the two cylinders into which said pair of ports respectively open, an abutment
for each cylinder, a shaft in the two cylinders having a piston head in each cylinder,
the two heads being oppositely arranged.
3rd. A rotary engine comprising the two cylinders and the single engine shaft
having the oppositely arranged piston heads in said cylinders..
4th. In combination, the pedestal, the two separate cylinders, a live steam
chamber in the pedestal opening into each chamber, exhausts from each chamber,
each chamber having a rocking abutment at the inner end of its induction port as
set forth, and the engine shaft having the piston heads in said cylinder.
5th. A rotary engine having a rocking abutment between its induction and
exhaust ports arranged to enter into a recess at the inner end of the induction port
and close the same when the piston head passes.
6th. The combination of the pedestal, the two cylinders, the separating plate,
cylinder heads, the shaft having the opposite piston heads, the rocking abutments
and induction and exhaust ports for each cylinder.
7th. A rotary engine shaft having the tapered journals in the stuffing boxes and
the tapered packing rings and adjusting means.
8th. A rotary engine having the steel or hard packing blocks or rings pressed out
by springs.
9th. A rotary engine having its piston heads provided with movable packing
blocks in its edges pressed out by springs.
10th. A rotary engine having movable packing rings in its sides yieldingly held
against the rotating disk on the engine shaft.
11th. A rotary engine having two separate cylinders and the single engine shaft
passing therethrough and having opposite piston heads therein.
12th. A rotary engine having separate steam chambers or cylinders and the single
engine shaft having piston heads in such cylinders, whereby a continuous pressure
and rotation of the shaft is produced.
Dated this 15th day of October 1891.
