PROVISIONAL SPECIFICATION.
An Improved Rotary Engine.
We, WILLIAM SLATER of 2 Vermont Street, Millwright, and THOMAS SLATER
of Daly Street, Deane Road, Pattern Maker, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows:-
This invention relates to an improved rotary engine capable of being driven by
either steam, water, or other fluids and consists of a casing or cylinder with one or
more compartments or divisions in each of which is mounted a disc fitted with
angular or other vanes, wings, or paddles in such a manner as to cause the least
possible resistance to the driving medium. The said disc or discs is mounted on a
centre shaft or spindle passing through a stuffing box at each end of the casing
or cylinder. Steam, water, or other fluid is admitted at any convenient part, and
the exhaust-outlet is disposed so that the exhaust can flow away in any convenient
manner. The exhaust from one disc may be directed or conveyed to the next and
following discs in successive order, the same being conducted by pipes or passages
suitably connected. The said pipes or passages may be increased in number and
provided with valves or taps to allow of the engine being rotated in either direction
at will. The centre shaft or spindle is mounted in adjustable or other bearings, and
may be provided with a fly wheel or wheels if necessary. The whole is mounted
on framework of any suitable description according to the position in which the
engine is to be fixed. An important feature of this invention is that it can be fixed
in almost any position without interfering with the working of the same,
engine may be regulated or controlled by a governor.

An Improved Rotary Engine.
We, WILLIAM SLATER of 2 Vermont Street, Millwright, and THOMAS SLATER
of Daly Street, Deane Road, Pattern Maker, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-

A is the casing or cylinder made in halves and provided with the flanges B,
which are secured together by bolts or other equivalents. The casing or cylinder A
is provided internally with any number of compartments or divisions C, and may
be of equal or unequal widths as shown in the drawings. In the casing or
cylinder A is mounted the disc D fitted with the vanes, wings, or paddles E. The
disc D is mounted on the centre shaft or spindle F, which passes through the
stuffing boxes G on the end covers H of the casing or cylinder A. The shaft or
centre F is mounted in the bearings I, which may be adjustable or otherwise. The
shaft or centre F may be provided with the fly-wheel or pulley J to transmit power
by a belt or other equivalents, or may be coupled direct as desired. The whole
is mounted on the framework or foundation plate K.
Steam, water, or other fluid forming the driving medium is admitted by the
pipe L and operates on the vanes, wings, or paddles E on the disc D. The vanes,
wings, or paddles E are disposed on the disc D as shown in Fig. 4 to cause the
least possible resistance to the driving medium. As the disc D is rotated by the
driving medium, the latter passes through the under passage M and operates on
the vanes, wings, or paddles E on the opposite side in the second compartment,
from whence it passes through the upper passage N, operates on the vanes, wings,
or paddles E² on the opposite side in the third compartment, and then passes by the
under passage O to the fourth compartment and operates on the vanes, wings, or
paddles E³, from whence it passes away through the exhaust or outlet pipe 1', and
so on, the operation being repeated according to the number of compartments or
divisions C. The latter are increased in width from the steam inlet to the exhaust
outlet to allow of equal, or almost equal, power being exerted by each separate set
of vanes, wings, or paddles as expansion takes place and pressure decreases.
compartment or division C may be provided with the outlet Q to allow condensed
water, in case steam is the driving medium, to flow into the chamber R, from whence
it passes away through the pipe S to a steam trap or other equivalents.
Each
The compartments or divisions C may be independent of each other and provided
with the valves T mounted on the spindle U, the latter being rotated by the spur
gear V and W from the shaft or centre F as shown in Fig. 5. The valves T may
be set in varying positions on the spindle U so as to allow them to open and close
at different times to ensure of the driving medium being admitted to give regular
turning and economise steam or other driving medium. If desired part of the
compartments or divisions C may be fitted with the valves T as shown in Fig. 7.
In lieu of the spur gear V and W for rotating the valves T we may employ the
eccentric X, rod Y, and lever Z shown in Fig. 8 to produce an oscillating or
reciprocating movement to the same. The eccentric X is fixed on the shaft or
centre T, and the lever Z on the valve spindle U.
Although we have shown the compartments or divisions C of varying widths
we would have it understood that they may be made equal, with or without the
valves T.

page_text: Two or more complete engines may be coupled to one shaft or centre for the
purpose of multiplying or increasing power.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a rotary engine the construction and arrangement of apparatus consisting
of a cylinder or casing with compartments or divisions of equal or unequal widths
and a disc provided with vanes, wings, or paddles of equal or unequal widths,
substantially as described.
2. In a rotary engine the construction and arrangement of apparatus consisting
of a cylinder or casing with compartments or divisions of varying widths, a disc
provided with vanes, wings, or paddles of varying widths, and passages for conveying
the driving medium from one compartment to another in successive order from the
inlet to the outlet, substantially as described.
3. In combination with the disc of a rotary engine the form of vanes, wings, or
paddles and the manner of disposing the same thereon, substantially as described
and as shown in Figs. 3 and 4.
4. The general arrangements, constructions, and combinations of parts composing
the improved rotary engine, as hereinbefore described and as illustrated in the
annexed drawings.
