PROVISIONAL SPECIFICATION.
Improvements in Rotary Engines, applicable as Pumps, Motors, or
Meters.
I, GEORGE LEWIS CONROY, of 37 Courland Grove, Larkhall Lane, Clapham,
in the County of Surrey, Mechanical Engineer, do hereby declare the nature of
this invention to be as follows:-
These improvements relate to a rotary engine applicable as a pump, motor, or
meter for water, or other fluid.
The improved engine is constructed with a central axis (forming as the case may
be the main driving, or the driven axis) upon which is mounted a wheel or circular
part having formed in it radially (say) four cylindrical chambers (or it may be
other number thereof) and in each cylindrical chamber is located with capability of
reciprocation a piston or part corresponding in contour to the cylindrical chamber.
Each piston or equivalent part is linked or connected to parts which by a ring or
other equivalent means are embraced or held to and caused to partake of the
eccentric motion, produced thereto relatively to the wheel by a fixed pin projecting
from the interior of the enclosing casing or cover.
Within the cover around its circumference are recesses communicating with inlet
and outlet channels or passages, the remaining portions of the face internally of
said case forming the dividing abutments between the ports. As the axis revolves
(in the case of a pump) the chambered wheel or drum rotates, carries around with
it the pistons and they being linked to the parts which remain attached to the
eccentric pin, such pistons are retracted and projected in turn and liquid or fluid
flows into the empty space formed as it comes opposite the inlet, and the parts
further rotating each piston is projected as it comes opposite the outlet, meanwhile
the liquid is caused to pass into the outlet port aud is ejected through the outlet
passage. The fixed pin may be applied on a bar across an opening formed in a
removable cover plate, and thereby an inspection opening provided which also
serves as a convenient channel for the application of lubricant.
By these means a rotatory engine is constituted distinguished by its chambers or
cylinders having each a definite capacity capable of forming a positive measure in
the case of a meter, and with other advantages particularly adapting it to serve as
a high speed pump or motor, to be driven by electric energy.

COMPLETE SPECIFICATION.
Improvements in Rotary Engines, applicable as Pumps, Motors, or
Meters.
I, GEORGE LEWIS CONROY, of 37 Courland Grove, Larkhall Lane, Clapham,
in the County of Surrey, Mechanical Engineer, 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 :-
These improvements relate to a rotary engine applicable as a pump, motor, or
meter for water, or other fluid.

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews by a cross sectional view one form of my improved rotary engine.
in which the inlet and outlet ports are on the periphery of the casing; the section
being taken on the line y-y of Fig. 2.
Fig. 2 shews the same by a sectional view taken on the line x-x, of Fig. 1.
Figs. 3 and 4 are views similar to the previous figures showing another form of
my invention, with the inlet and outlet channels on the side of casing.
Fig. 5 shews by a sectional view and Fig. 6 by a side view, an arrangement in
which some of the parts are modified.
Fig. 7 shews by a side view, Fig. 8 by a sectional view and Fig. 9 by a plan
view the piston in detail.
Fig. 10 shews by a separate view the ports in side of casing as in the modification
shewn in Figs. 3 and 4.
.
Figs. 11 and 12 shew the connecting rods by edge view and side. view
respectively.
Figs. 13 and 14 shew by front view and side view respectively a ring or hoop to
be described.
Fig. 15 shews an interior view of the face A³ of the case A, or it may be the
. like face of a plate in substitution for said fixed face A³ and shewing the grooves h
and W.
Fig. 16 shews in section a detail being a modification wherein the groove his
shewn half in each of the two adjacent faces A³ and B.
The improved engine is constructed with a central axis i (forming as the case
may be the main driving, or the driven axis) upon which is mounted a wheel or
circular part B having formed in it radially (say) four cylindrical chambers a, a', a², a³,
(or it may be other number thereof) and in each cylindrical chamber is located
with capability of reciprocation a piston or part b, 61, 62, 63 corresponding in
contour to the cylindrical chamber and provided with suitable packing rings sce
Fig. 8.
Each piston or equivalent part is linked or connected to controlling pieces
or parts c, c¹, c³, the projections on each of which by a ring or rings, f
or other equivalent means are embraced or held to a pin e and caused to partake
of the eccentric motion produced thereto relatively to the wheel B by the fixed
pin e projecting from the interior of the enclosing casing or cover A.
The casing A is provided with suitable recesses d, d, having abutments d' d' with
set screws d², d² for adjusting the abutments against the wheel B.
hh is a groove here shewn (see Fig. 15) as formed around the face of the inner
wall or face of the casing. As with a conducting channel h leading therefrom to
the suction side of the pump that any liquid escaping between the faces of the
wheel B and this face A³ will be intercepted and drawn away into the suction pipe.
Or the groove h may be in the adjacent face of the wheel B and the conducting
groove be formed in the face A. Or the groove may be formed one half in
section in each of the adjacent faces of the parts B and A³ (see Fig. 16) and the
groove or channel in the face A' or several grooves may be employed in place
of only one.
Within the cover A around its circumference are recesses communicating with
inlet and outlet channels or passages A1, A2 see Figs. 1 and 2 the remaining portions
of the face internally of said case forming the dividing abutments between the
ports.
In the arrangement shewn in Figs. 3, 4 and 10 the openings or ports leading
to the inlet and outlet channels A' and A' pass through the packing ring in a
recess d formed in the side of the casing A. is a ring fixed to the periphery of
the disc B to cover the ends of the cylinders a, a', a³, a³.
The abutments d' which bear against the side of the disc B, are shewn best in
Fig. 10.

page_text: In the modification shewn in Figs. 5 and 6 the abutments d' are formed as part.
of a packing ring d' which encircles the disc B.
This packing ring d has openings or ports as formed therein which communicate
with the inlet and outlet channels A' A' formed on the periphery of the casing,.
see Fig. 1; d' is elastic packing.
As the axis i revolves (in the case of a pump) the chambered wheel or drum B.
rotates, carries around with it the pistons b, b', b, b' and they being linked by
means of crosshead pins p, p, p, p, to the connecting rods or parts c, c¹, c³, c
which remain attached to the eccentric pine such pistons are retracted and
projected in turn and liquid or fluid flows into the empty space formed as it comes.
opposite the inlet and the parts further rotating each piston is projected as it comes
opposite the outlet A' meanwhile the liquid is caused to pass into the outlet port A"
and is ejected through the outlet passage.
The fixed pin e may be applied on a bar across an opening formed in a removable
cover plate, and thereby an inspection opening is provided which also serves as a.
convenient channel for the application of lubricant.
By these means a rotatory engine is constituted distinguished by its chambers or
cylinders having each a definite capacity capable of forming a positive measure in
the case of a meter, and with other advantages particularly adapting it to serve as.
a high speed pump or motor, to be driven by electric energy.
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 :-
1. In a rotary engine applicable as a pump, motor or meter the construction
and arrangement or combination of a main axis, a disc with piston chambers,.
having each a piston therein, said piston being linked to connecting rings on an
axis eccentric to the main axis, suitable packing parts and enclosing casing,
substantially as set forth.
2. In a rotary engine of the character described the arrangement or com-
bination of parts for packing the disc and cover by means of a ring enclosing
the disc and provided with ports as set forth with respect to Figs. 5 and 6.
3. In a rotary engine applicable as a pump, motor, or meter the construction
and arrangement of parts as set forth in respect of Claim 1 in combination with
a groove or channel or grooves or channels around the face of the end wall or face
of the casing or its equivalent with a conducting channel or channels therefrom
leading to the suction side of the pump, or through the casing to waste or. other-
wise, substantially as set forth.
