being also Applicable for Motive Power.
We FREDERICK HARVARD STACEY, of Heeley Bridge Foundry, Manufacturer, and
HENRY WILKINSON, Belgrave Square, Highfield Engineer both of Sheffield in the
County of York do hereby declare the nature of this invention to be as follows:-
Our improvements in apparatus for blowing exhausting, and pumping, and which
when modified may be also used for transmitting motive power; are in the
construction of a blower, to be driven by power for example: carried out as follows.
Two or more vanes, but preferably two, are mounted by one of their lower edges
upon a coupling attached to or made solid with the end of the driving shaft, the said
vanes with the coupling, being arranged to revolve within the outer casing of the
apparatus, to which the main bearing of the driving shaft is secured; the outer end
of the shaft beyond the driving pulley being carried by a standard or the like. Each
vane is shaped to the form of a segment of a circle or thereabouts, the path of their
revolution giving the form to the interior of the casing.
A circular division plate, or disc, is mounted on the end of a second shaft fixed at
a convenient angle to the driving shaft, the said disc having a ball or sphere round
its centre, one balf of which revolves with the disc, the other part on the opposite
side of the disc having an elongated portion secured to the casing, and forming the
bearing for the disc shaft.
The disc is so placed as to divide the interior of the casing obliquely in two
compartments, and it is provided with two slots cut radially through it, into which
the vanes fit loosely, and through which they travel from side to side while revolving,
and thus impart a rotary motion to the disc, by carrying it round with it, but this
motion may be imparted by other means.
The outer casing is made in halves bolted together, the sides being conical,
corresponding with the angle of the segmental vanes and disc; and having on each

page_text: side an inlet, and an outlet port; the inlets being on one side the 'fixed points where
the sides of the disc come in close contact with the side of the casing, and the outlets
on the other side.
When the vanes and disc are revolving the outlets are open to the front of the
vanes, and the inlets to the back, thus ensuring the constant delivery of the whole 5
contents of the casing at each revolution.

COMPLETE SPECIFICATION,
Improvements in Apparatus for Blowing, Exhausting, and Pumping,
being also Applicable for Motive Power.
We FREDERICK HARVARD STACEY of Heeley Bridge Foundry, Manufacturer, and
HENRY WILKINSON, Belgrave Square, Highfield, Engineer both of Sheffield in the
County of. York 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 :-
Our invention is for improvements in the construction of apparatus for blowing
exhausting, or for pumping, and the principle may be also used with modifications in
the mechanical details in constructing a motor.
In carrying out our invention in constructing a blowing apparatus for which
purpose it is especially adapted, we will describe a machine as illustrated in the
annexed sheet of drawings, in which :-
Fig. 1, is an elevation of the apparatus.
Fig. 2, is a sectional elevation of same.
Fig. 3, is an enlarged view of a vane.
Fig. 4, shows one of the slits in the disc, and the edge of vane.
Fig. 5, the vane, the guide or slide and part of disc.
Fig. 6, one of the guides or slides.
Two or more vanes A, but preferably four, such as are represented in Fig. 3, are
secured in any suitable manner such as by screwholts, to the end of the driving
shaft B, which is suitably formed for that purpose.
We prefer to support the driving shaft B, and driving pulley C, partly by a
bearing D, formed in the casing E, and partly by the standard F, both of which are
erected upon and secured to a base plate G.

page_text: Each vane is shaped to the form of a segment of a circle or thereabouts, and the
path of their revolution described the configuration of the interior of the casing E,
clearly shown in Fig. 2.
A circular division plate or disc H is mounted on the end of a second shaft I,
fixed diagonally or at a convenient angle from the driving shaft B, the said disc
having its centre covered by a ball or sphere J, one half of which revolves with the
disc, the other half having an elongated part secured to the casing, and forming the
bearing for the disc shaft I.
The disc H is made of two circular plates firmly secured together, but with a
space between them as seen in Figs. 2 and 5, to admit the insertion of self adjusting
slide pieces K. The disc is also provided with four radial slots L, preferably tapered
as seen in Fig. 4, and sufficiently wide to allow the disc to revolve freely with the
vanes. To allow of a certain amount of twisting action in the vanes as they move to
and fro through the slots L, when they and the disc are made to revolve, we introduce
between the plates of the disc, the making up pieces or slides K, Fig. 6, the top edges
being seen in Fig. 5.
These slides are shaped at one end to fit upon a circular boss M on the shaft I
between the disc plates, on which there is a short radial movement regulated by the
stop pieces N which are attached to the disc. It will therefore be understood that the
vanes fit through the slots O in the slides, and that while moving laterally to and fro,
the slides can also move backwards and forwards between the disc plates, the slides
acting as baffle plates to prevent leakage.
Although the vanes will cause the disc to revolve when the apparatus is set in
motion, we may if desirable gear the two parts together by teeth or their equivalents
at the point where the disc comes in contact with the end of the driving shaft B,
seen in Fig. 2.
The disc is so placed that it divides the interior of the casing obliquely into two
compartments, each compartment having an inlet and an outlet, the inlets being on
one side the fixed points where the sides of the disc come in close contact with the
side of the casing, and the outlets being on the other side, the said outlets would
usually converge to form a single outlet P. The inlet may consist of a number of
openings made at Q through the casing, and the outlet passage is formed in the
casing at R.
When the apparatus is at work, each vane during its revolution, delivers one
quarter of the whole contents of the outer casing from each of the beforementioned
compartments.
Having thus particularly described and ascertained the nature of our invention,
and in what manner the same is to be performed we declare that what we claim is :-
1-The improved apparatus for blowing, exhausting, or pumping constructed and
arranged substantially as hereinbefore described, and as shown in the drawings.
2-In an apparatus for the purpose hereinbefore specified, the combination of a
diagonally supported disc H, capable of being revolved, with two or more horizontally
supported revolving vanes A, arranged to work together, substantially as hereinbefore
described, and as shown.
Dated the 16th day of November 1888.
