Improvements in Steam, Gas, and other Fluid-pressure Engines,
applicable also to Pumps.
I, HERBERT AUSTIN, Works Manager to the Wolseley Sheep Shearing Machine
Company, Limited, of Sydney Works, Alma Street, in the City of Birmingham,
Manufacturers, do hereby declare the nature of this invention to be as follows:--
This invention relates, more especially, to high speed steam, gas, and other
fluid-pressure engines, such as are required for driving cycles, motor cars,
dynamo-electric machines, and the like; but is applicable to steam, gas, and
other fluid-pressure engines generally, and also pumps.
According to this invention, the outer end of the connecting-rod of the engine
or pump is provided with a pin which is fixed rigidly thereto, preferably by
forming it in the same piece of metal therewith, and projects from opposite
sides thereof. The parts which thus project are a turning fit within bearings
formed in fly wheels, discs, or cranks, between which the rod passes. The con-
necting-rod pin is thus used in place of the ordinary crank-pin, and the bearings
for the pin which are within the wheels, discs, or cranks, are in lieu of the
bearing ordinarily formed within the connecting-rod end. In the case of engines
(and of pumps) of a compact boxed-in type, such as are required to occupy a
small space, the fly wheels, discs, or cranks, may be mounted to turn upon fixed
pins or studs projecting from the inner sides of the boxing, or they may have
pins or studs formed therewith, or rigidly fixed thereto, which turn within fixed
bearings projecting from the sides of the boxing. When a wheel, disc, or crank,
turns upon a fixed pin or stud, movement may be transmitted from or to it
through the medium of gear of which a spindle passes through the side of the
boxing but when it is provided with a pin or stud which turns within a fixed
bearing, the pin or stud may be carried through to the outside of the boxing.
The inner end of the connecting-rod is constructed, according to this invention,
similarly as the outer end above described; and, in the case of an engine, or
pump, in which the rod is connected direct with the piston, the parts of the
pin which project at opposite sides of the rod turn within bearings formed in
the heads of eye-bolts of which the shanks or screwed portions pass through the
inner end of the piston and are secured in place. In the case of an engine or
pump in which the connecting-rod is connected with the outer end of a piston
rod, the parts of the pin which project at opposite sides of the inner end of the
connecting-rod may fit within bearings formed in a cross-head or other part to
which the rod is to be connected, provided the same is constructed so that the
bearing at one side is detachable.

I, HERBERT AUSTIN, Works Manager to the Wolseley Sheep Shearing Machine
Company, Limited, of Sydney Works, Alma Street, in the City of Birmingham,
Manufacturers, 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, more especially, to high speed steam, gas and other
fluid-pressure engines, such as are required for driving cycles, motor cars,
dynamo-electric machines, and the like; but is applicable to steam, gas, and
other fluid-pressure engines generally, and also to pumps.
According to this invention, the outer end of the connecting-rod of the engine
or pump is provided with a pin which is fixed rigidly thereto, preferably by
forming it in the same piece of metal therewith, and projects from opposite
sides thereof. The parts which thus project are a turning fit within bearings
formed in fly wheels, discs, or cranks, between which the rod passes.
The con-
necting-rod pin is thus used in place of the ordinary crank-pin, and the bearings
for the pin which are within the wheels, discs, or cranks, are in lieu of the
bearing ordinarily formed within the connecting-rod end. In the case of engines
(and of pumps) of a compact boxed-in type, such as are required to occupy a
small space, the fly wheels, discs, or cranks, may be mounted to turn upon fixed
pins or studs projecting from the inner sides of the boxing, or they may have
pins or studs formed therewith, or rigidly fixed thereto, which turn within fixed
bearings projecting from the sides of the boxing. When a wheel, disc, or crank,
turns upon a fixed pin or stud, movement may be transmitted from or to it
through the medium of gear of which a spindle passes through the side of the
boxing but when it is provided with a pin or stud which turns within a fixed
bearing, the pin or stud may be carried through to the outside of the boxing.
The inner end of the connecting-rod is constructed, according to this invention,
similarly as the outer end above described; and, in the case of an engine, or
pump, in which the rod is connected direct with the piston, the parts of the
pin which project at opposite sides of the rod turn within bearings formed in
the heads of eye-bolts of which the shanks or screwed portions pass through the
inner end of the piston and are secured in place. In the case of an engine or
pump in which the connecting-rod is connected with the outer end of a piston
rod, the parts of the pin which project at opposite sides of the inner end of the
connecting-rod may fit within bearings formed in a cross-head or other part to
which the rod is to be connected, provided the same has caps which form the lower
sides of the bearings and are readily removable, or is constructed so that at
any rate one of the bearings is detachable; or provided (in case there is room to
push the pin endways into its bearings) that suitable means are adopted for
fixing the pin to the rod in a detachable manner, such as by a transverse pin or
cotter.
In order that the invention may be clearly understood I have illustrated, by
way of example, certain practical applications of the same, to which I will now
more specifically refer.
Figure 1 is a vertical section, taken along the centre of an inverted cylinder
oil engine. Figure 2 is a vertical section, also, through such engine, taken
along the centre thereof, but in a plane at right angles to that of the section
shown by Figure 1, in both views the connecting-rod is shewn, for convenience,
in elevation.

page_text: A is a box or casing forming the main framing of the engine. B is the
cylinder, and U two discs acting as fly wheels and mounted to turn upon fixed
pins or studs D which have a common axis. These pins are fixed, respectively,
rigidly to the opposite sides of the box A. The lower or outer end of the con-
necting-rod E is formed with a pin a a which projects from the opposite faces
thereof, and these projecting portions of the pin enter corresponding holes or
bearings formed in the discs C. The discs are prevented from moving towards
one another on the studs 1 by the outer or lower end of the connecting-rod which
fits in between the inner faces of the disc bearings for the pin a a, and the discs
are prevented from moving outwards from one another by collars or facings b
formed around the hinder ends of the studs D.
The inner or outer end of the connecting rod E is formed also with a pin, a¹, a¹,
which projects at opposite sides thereof. These projecting portions a' fit within
the eyes e of eye bolts d.
The power is shewn to be transmitted from one of the discs C through the
medium of a pinion e fixed upon the rear portion of its boss, of a spur wheel f
with which such pinion gears, of a short shaft g which carries the wheel f and
passes through one side of the box A and through a bearing which projects
from the outside of the casing, and of a pinion i fixed upon the outer end of the
shaft g.
In lieu of the fixed studs 1) upon which the wheels or dises turn, short pins
or axles may be used upon which the discs or fly wheels are fixed, or with which
they are formed, and which are themselves mounted to turn in bearings formed
in the sides of the box A. In this case, the power may be transmitted from an
end of one of the pins or axles which projects outside the box.
Figures 3 and 4 illustrate a method of connecting the inner or upper end of
the connecting rod with the cross-head of an engine. Of these views, Figure 3
is a vertical section, looking edgeways of the connecting-rod, and Figure 4 is an
elevation looking in a direction at right angles to Figure 3. The bearings of
the cross-head within which the projecting portions a' of the pin are fitted are
each provided with a cap k which is readily removed when it is desired to dis-
connect the connecting-rod from the cross-head.
The connecting-rod pins a a and a al may, of course, be formed separately
from the connecting-rod, if desired, and be rigidly fixed thereto, but it is found
to be much more convenient and satisfactory to form the pins in the same piece
of metal with the connecting-rod.
The application of the invention to fluid pressure engines generally, and also
to pumps, will be quite obvious without further illustration or description.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is;
1. In a steam, gas, or other fluid-pressure engine, or pump, a connecting-rod
having a pin formed with or rigidly fixed to its outer end and projecting from
opposite sides thereof and fitting within holes or bearings formed in fly wheels,
dises, or cranks, which are mounted to turn upon or with separate studs, pins,
or axles, which have a common axis, substantially as described.
2. In a steam, gas, or other fluid-pressure engine, or pump, a connecting-rod
having a pin formed with or rigidly fixed to its inner end and projecting from
opposite sides thereof and fitting within bearings carried by the piston or cross-
head, substantially as described.
