AN IMPROVED VERTICAL ENGINE
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We, WILLIAM ROBERTSON, of 31 Lombard Street, in the City of London,
Merchant, and GEORGE ABRAHAM GOODWIN, of Fenchurch House, Fenchurch
Street, in the City of London, Engineer, do hereby declare the nature of the said
invention for AN IMPROVED VERTICAL ENGINE to be as follows:-
"
Our invention relates to that type of steam engine known as vertical," in
which the cylinder is arranged vertically above the crank shaft, and is designed to
render the said engine more effective in work, and cheaper in construction.
The frame of the engine is made of an A form in side elevation, the cross bar
being used or omitted as may be desired, the two sides forming the A being
externally in plan of an oval shape or of two semi-circles struck from centres at
some distance from each other.
The upper portions of the two sides of the A frame are cored hollow, the inner
sides of the frames forming the guides, and consisting of two arcs of a circle
described from the axis of the engine as a centre.
The top of the A frame is united in the single casting by a plate which forms
the lower cylinder cover.
The bottom of the frame is completed by a flange, which may bed upon a box
bed-plate when required, and carries the two crank-shaft bearings.
The lower bed-plate when used is in the form of a hollow box casting, forming a
tank, and dished under the throw of the crank, the bed being extended when
required to carry a boiler together with the engine.
The cylinder is bolted to the cover plate at the top of the A frame.
The valve spindle guide is cast as a bridge in one piece with the valve chest.
The governor is of the high speed type, and has the governor balls suspended
from an overhead cone bearing. The body of the governor forms a combined stop
and throttle valve, the valve being of the piston type, working over 2 or more
grids.
The lower flange of the stop valve is provided with a cover, stuffing box, and
gland, and this cover is provided with a semi hemispherical hood, which carries
a taper revolving hollow spindle. The hollow spindle carries the governor balls,
and contains a spiral spring, which re-acts against the rise of the balls-A small
pindle operated by the governor balls passes through the centre of the hollow

page_text: suspended spindle, and actuates the throttle valve, being connected thereto by a
revolving union. The governor may be driven by gut, or belting, with or without
bevil gear.
This arrangement of the governor allows the point of suspension of the ball
levers to be truly in the axis, and so ensures a more perfect and sensitive action,
than in the case of governors whose ball levers have their points of suspension on
either side of the axis of rotation.
Other details and parts which in combination with the above described improve
ments serve to make a complete vertical steam engine being of the usual known
kind and arrangement I do not here more particularly describe.
Dated this 90th day of September 1884.

We, WILLIAM ROBERTSON, of 31 Lombard Street, in the City of London,
Merchant, and GEORGE ABRAHAM GOODWIN, formerly of Fenchurch House, Fen-
church Street, in the City of London, but now of 2 Victoria Mansions, in the City
of Westminster, Engineer, do hereby declare the nature of our invention for "AN
IMPROVED VERTICAL ENGINE" and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
Our invention relates to that type of steam engine known as vertical, in which
the cylinder is arranged vertically above the crank shaft, and is designed to render
the said engine more compact in arrangement, effective in work, and cheaper in
construction.
In order that our invention may be the better understood, we now proceed to
describe the same, reference being had to the drawings hereto annexed, and to the
letters and figures marked thereon.
Figure 1 is a front elevation of the said engine.
Figure 2 is a side elevation of the same.
Figure 3 is a sectional detail of the governor.
Figure 4 is a sectional plan of the framing.
A is the frame of the engine which it will be seen is of special form, and in side
elevation, is in the shape of a letter A the cross bar being used, or omitted as
desired. The two sides of the frame are externally, in plan, of an oval shape, or of
two semicircles, struck from centres at some distance from each other, as shown in
the sectional plan (figure 4). The upper portion of the two sides of the frame are
cored hollow, the inner sides of the frames forming the guides B, which consists of
two arcs of a circle, described from the axis of the engine as a centre. The top of
the A frame is united in a single casting by a plate C, which forms the lower cover
of the cylinder D, the bottom of the frame is connected by a web and flange E,
which carries the two crank shaft bearings F F, and is conveniently fitted upon the
box bed-plate G.
The lower bed plate G, when used, is in the form of a hollow box casting,
forming a tank, and dished under the throw of the crank, the bed being extended
when required to carry a boiler together with the engine. The cylinder B is bolted
to the cover plate on the top of the A frame. The valve spindle guide H is cast as
a bridge in one piece with the valve chest.
The governor K is of the high speed type and has the governor balls L suspended.
from an overhead cone bearing 1, shown in the sectional view (figure 3). The body
of the governor M forms a combined throttle and stop valve, as the steam may be
shut off either by the rise or fall of the governor balls L, or by the screw down
action of the hand wheel N respectively. The valve m, is of the piston type
working over two or more grids. The lower flange of the valve casing is provided
with the cover P, stuffing box and gland, and this cover is provided with the semi-
hemispherical hood Q which carries a taper revolving hollow spindle q. This
hollow spindle carries the governor balls L and contains a spiral spring p which
reacts against the centrifugal action of the balls. The small spindle r, operated by

page_text: the governor balls L, passes through the centre of hollow suspended spindle and
actuates the throttle valve m, being connected thereto by a revolving union R.
The governor may be driven by a gut or belting, with, or without bevel gear.
This arrangement of the governor allows the point of suspension of the ball
levers to be truly in the axis of rotation, and so ensures a more perfect and sensitive
action than in the case of those governors the ball levers of which have their points
of suspension on either side of the axis of rotation.
The feed pump is fitted with a three way cock upon its suction pipe, which can
be used for regulating the feed, or in alternative positions can be employed to
permit the suction to be drawn either from the tank below the boiler, from an
outside supply, or permits the tank to be filled from the said outside source of
supply respectively.
'
Other details and parts, which in combination with the above described improve-
ments serve to make a complete vertical steam engine, being of the usual known
kind, and arrangements, we do not here more particularly describe.
Having now particularly described and ascertained the nature of our inven
tion and in what manner, the same is to be performed, we declare that what we
claim is
1st The construction of a vertical engine, comprising an A frame of the special
form illustrated, with bored guides therein, and cylinder attached thereto, and
carrying the crank shaft bearings, the cylinder being provided with a high speed
governor, and solid cast valve spindle guide, in combination with the three way,
pump cock and other known details, to form a complete engine, substantially as
described.
2nd In such a vertical engine the construction of a high speed governor in which
the ball levers are suspended from a pivot truly in the axis of revolution, the
revolving spindle being carried, in a cone bearing, and combined with other usual
parts of a governor, the whole operating a combined throttle and stop valve,
substantially as described.
