improvements in Rotary motore,
I, CHARLES BURGESS, Stanley Villas, Livingstone Road, Kings Heath, Worcester-
shire, Musician, 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;-
My invention is a rotary motor having for its objects the using of steam or
other power to the greatest advantage, and causing when used no vibration in
steam vessels or road vehicles. The general arrangement of this invention is
represented in Fig. I of the accompanying drawings. Fig. II shows a partly
vertical section, through the body, of the different parts of the motor. Fig. III
shows a side elevation of a valve through which power enters the motor. It moves
forward, or backward to admit or exclude power.
Fig. IIII is an end view of Fig. III it shows 1st. The passage for steam. 2nd.
The ends of pivots, Fig. V shows the end view of cylinder in which Fig. III
works, it has an each side an oblong hole corresponding to the steam passage m
in Fig. III and IIII, it is at its sides pinned to the body of motor. Fig. VI shows
surface of two plates which are pinned to the ends of Fig. V for the purpose of
confining Fig. III to cylinder, Fig. V, and each has a hole for pivots of Fig. III
to work in.
I will now explain the drawings in detail.
Fig. I shows the outlines of all the parts of this invention and will be refered
to in explaining the other drawings. Fig. II, a is an axle to which is secured a
drum b the face of which is one side of a cylindrical chamber, a. c (Fig. 1)
is a fan fixed on b and made to fit in chamber a, and is for
the purpose of receiving the force admitted to the chamber : dis a
flanged cylinder of larger diameter than 6 and is the opposite side of chamber.r
to the one formed by b; e e e e are two circular plates pinned to flanges of d as
shown at e (Figs. I and II) and form remaining two sides of chamber, on these
plates, e, is a thickening on the outer sides to allow a circular groove g to be
turned, into which grooves two rings g¹ are inserted to act as packing against
sides of b. g is a ring in groove g pressed against side of b by helical springs h
placed in holes drilled through thickening and kept in their places by a plate
which is secured to thickening by pins r k is a stud and lever (see Figs. III
and V) is a cam arrangement to work stud k up and down.

page_text: Letters m, m, n, o, p, k, z, Fig. I show the position of an oscillating valve which
has a passage through it for conducting steam from steam pipe o to chamber
to force the fan around: in large motors the steam strikes the fan at a right angle,
thus getting all the force possible. A cut off (shown at u, Fig. I) at the steam
pipe end of the passage, acts as an abutment after the steam is cut off, to allow
the steam to expand. When the valve plug is in position as at m, o, Fig. I the
steam rushes through the passage (until it is cut off,) into chamber x Fig. I.
When the valve plug is in position as at m m Fig. I the steam passage is closed
at both ends and the fan has room to pass under the valve plug.
Fig. III is a side view of the plug of the valve, (m m n o P k z z Fig. I) m is
a passage for steam through the plug, from steam pipe to chamber x; n Fig. III
is the axle on which the plug oscillates, & Fig. III is a stud on the end of a lever P
Fig. III and in connection with the lever, is for the purpose of moving the plug
backward and forward by the action of the cam Figs. I and II. P Fig. III
is a lever projecting from n Fig. III and in connection with k Fig. III is for the
purpose just set forth.
Fig. IIII is an end view of Fig. III.
Fig. V is a side view of cylinder in which Fig. III works it has an aperture
in one end to let steam into passage m of Fig. III, and at the other end an aperture
to allow the steam to pass into chamber a Fig. I.
Fig. VI represents a plate pinned to the end of Fig. V for the purpose of keeping
Fig. III in its place, it has a hole in which axle n Fig. III works.
Fig. VII shows the top of the valve, the steam pipe o and the exhaust s; the
other parts shown in this drawing have been shown and explained before.
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:
First. The valve for admitting steam to the motor at the point where it has
the greatest power.
Secondly. The foregoing combination of all the parts for the purpose of using
steam to the greatest advantage.
