PROVISIONAL SPECIFICATION.
Improvements in Motors for Driving Centrifugals and similar
Machines.
I, ROBERT WILLIAMSON, of the Firm of Pott, Cassels and Williamson, Engineers
and Founders, Motherwell, in the County of Lanark, do hereby declare the nature
of this invention to be as follows:-
This invention relates to centrifugals or similar machines of the type in which
the baskets or other rotating parts are driven by the direct application to their
shafts of turbines or water motors, and it has for its object to dispense with the
use of the pumps which are required for forcing the water in a stream against the
vanes or buckets of the turbines.
To that end I employ in lieu of the pumping apparatus, an injector or nozzle
in which live or exhaust steam is supplied to impel a stream of water through an
orifice or orifices in the form of a jet or jets against the vanes, buckets or blades
of a turbine or wheel on the rotating shaft. Or instead of a single injector a
number of injectors may be fitted at various points around the turbine, the injectors
being attached or combined in any convenient way with the casing of the turbine
which may be applied to over driven or under driven centrifugals or similar
machines.

Improvements in Motors for Driving Centrifugals and similar
Machines.
I, ROBERT WILLIAMSON, of the Firm of Pott, Cassels and Williamson, Engineers
and Founders, Motherwell, in the County of Lanark, 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 centrifugals or similar machines of the type in which

page_text: the baskets or other rotating parts are driven by the direct application to their
shafts of turbines or water motors, and it has for its object to dispense with the
use of pumps which are required for forcing the water in a stream against the
vanes or buckets of the turbines.
To that end I employ in lieu of the pumping apparatus an. injector or nozzle
in which live or exhaust steam is supplied to impel a stream of water through an
orifice or orifices in the form of a jet or jets against the vanes, buckets or blades
of a turbine or wheel on the rotating shaft. Or instead of a single injector a
number of injectors may be fitted at various points around the turbine, the injectors
being attached or combined in any convenient way with the casing of the turbine
which may be applied to over driven or under driven centrifugals or similar
machines.
In the accompanying drawings which illustrate the Invention Figure 1 is a
vertical section of a Weston Centrifugal machine to the driving spindle of which
my improved water motor is shown attached, and Figure 2 is a sectional plan of
the motor. The motor consists of a vane or bucket wheel A of any well known
type which is secured on the driving spindle B of the centrifugal machine C.
The motor is enclosed by a casing D attached to the roof of the building or other
fixture and this casing is fitted with a number of jet nozzles E directed against
the vanes a of the motor A. The water is led to these jet nozzles E from an annular
water space D¹ formed in the casing D and the water supply is directed thereto
by an injector F provided with the usual water inlet f steam inlet f¹ overflow f
and delivery f³ the latter being connected to the annular water space D¹ of the
casing D. An outlet passage D³ is formed in the casing D for the discharge of
the water used in operating the motor.
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 combination with a centrifugal or similar machine a water motor consisting
of a turbine or bucket wheel secured on the driving spindle of the machine and
operated by a jet or jets of water impelled by means of an injector or steam jet
substantially as described.
