PROVISIONAL SPECIFICATION.
An Improved Rotary Fluid or Steam Motor and Meter.
ROBERT WATTS 31 M Kerrell Road Peckham Pattern Maker do hereby
declare the nature of this invention to be as follows :—
This invention consists of the improved construction and arrangement of a fluid
motor or engine of the rotary type which may also act as a meter and be made
to indicate the quantity of fluid passing through same.
To carry my invention into practise I provide an outer casing or body having
a circular bore. In this casing a hub or a drum of a smaller diameter is suitably
mounted having its axis of rotation parallel to the bore in the said casing but
not in the centre of the said bore thus having an approximately crescent shaped
space. This hub is provided with vanes or flaps having a curvature similar to
that of the hub, controlled by suitable springs and hinged or pivoted thereto.
The hub has perforations in its sides for the exit of the fluid which enters the
hub at a convenient part thereof preferably the bottom. It will be seen that
owing to the centre of the hub being excentrically set in relation to that of the
bore of the casing, that upon revolving the hub the vanes will alternately open
and close upon the hub, the controlling springs tending to keep the vanes open.
The hub is adjusted in the said bore so that the vanes are closed upon the hub
when opposite that part of the bore which is nearest the hub centre; the vanes
being most open when at that part of the bore which is farthest from the hub
centre, suitable friction rollers may be provided between the vanes and bore if
desired. An aperture is provided in the bore for the exit of the fluid. The
revolution of the hub is dependent upon the action of the fluid on the vanes.
The exit and entry ports are so arranged as to cut off the fluid supply at suitable
intervals of the hubs revolution; the hub being suitably chambered. It will be
seen that my invention is applicable to any purpose in which the quantity of fluid
passing through a vessel is required to be registered, such as a water meter in
which case the hub is connected to suitable indicating or recording mechanism.
The ends of the outer casing or bore are covered by plates of a suitable
description which serve to support the hub and its bearings. If desired the
outer casing and the lower plate may be formed integral with one another.

COMPLETE SPECIFICATION.
An Improved Rotary Fluid or Steam Motor and Meter.
ROBERT WATTS 31 McKerrell Road Peckham S.E. 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 consists in the improved construction & arrangement of a fluid
motor or engine of the rotary type which may also act as a meter to indicate the
quantity of fluid passing through same.
Referring to the annexed drawings

page_text: To carry my invention into practice I provide an outer casing or body a having
a circular bore. In the bore of this casing a a hub or drum b of a smaller diameter
is suitably mounted on a fixed chamber chaving its axis of rotation parallel to the
bore in the said casing a but not in the centre of the said bore thus leaving an
approximately crescent shaped space. This hub b is provided with vanes or flaps d
having a curvature similar to that of the hub controlled by suitable springs e which
enter the recesses in the walls of the hub b; and hinged or pivoted thereto at f.
The hub has perforations in its sides shown at points g for the passage of the fluid
which enters the hub at a convenient part thereof preferably the bottom through
the ports in the bottom plate i. It will be seen that owing to the centre of the
hub being excentrically set in relation to that of the bore of the casing a that
upon revolving the hub the vanes & will alternately open and close upon the
hub the controlling springs e tending to keep the vanes d open. The hub bis
adjusted in the said bore so that the vanes are closed upon the hub when opposite
that part of the bore which is nearest the hub centre; the vanes & being most open
when at that part of the bore which is furthest from the hub centre, suitable
friction rollers may be provided between the vanes and bore if desired indicated by
the dotted circlej. An aperture k is provided in the bore for the exit of the fluid.
The revolution of the hub is dependent upon the action of the fluid on the
vanes d.
The port in the fixed chamber is so placed thereon that the supply of
water is cut off from the compartment formed by the vanes just before the water
begins to discharge from same through the exit part k.
It will be seen that my invention is applicable to any purpose in which the
quantity of fluid passing through a vessel is required to be registered, such as a
water meter, in which case the hub is connected to suitable indicating or recording
mechanism fixed in a suitable position such as in the space n. The dotted lines o
representing the spindle operating same.
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
In rotary motors or meters, in combination; a casing having a bore, with exit
and entry ports and a revolving perforated hub excentrically set in the bore in
the said casing and curved vanes pivoted to the hub and controlled by springs;
a fixed chamber communicating with the entry ports in the said casing and
carrying the revolving perforated hub with recording or indicating mechanism,
substantially as described.
