AN IMPROVED HORIZONTAL ENGINE
Year: 1884

page_text: 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 HORIZONTAL ENGINE to be as follows:-
Our Invention relates to that class of Steam Engines known as "Horizontal,"
and consists of improvements in construction, whereby the Engine is rendered
more effective and cheaper in construction.
To construct our improved Horizontal Engine we cast the Cylinder and Guides
together in one piece, the lower portion of the Guides, which are preferably made
of circular section suitable for being bored, having two feet or flanges for attaching
the guides, and thus the Cylinder, to the bed.
Where the Engine is of short stroke the cylinder may be allowed to overhang
the bed, but when of long stroke, these flanges or feet are carried along the sides
of the cylinder as well as the guides, and the bed is elongated 'to receive them-
The valve spindle guide may be cast in one piece with the cylinder or separately
attached as desired.
We provide the Crosshead with loose slippers of cast iron, gun metal, or other
material, turned preferably on their external circumference to a circle from the
central axis of the cylinder, so as to fit the bored surface of these guides, and
provided with suitable appliances for taking up the wear.
The bedplate may be conveniently widened at the Crank end, so as to carry the
two main crank bearings, cast with the frame, at an angle of 45°, and the bed-
plate may also be dished out between the bearings to admit of the play of the
crank.
•
The Governor is of the high speed type, and is preferably suspended instead of
being supported from below.
It is constructed as follows:-
The body forms a combined stop and throttle valve, the valve being of the
piston type working over two or more grids.
The bottom flange of the stop valve is provided with a cover and stuffing box
and gland.
This cover has cast on with it a hemi spherical hood with a boss at the lower
extremity.

page_text: This boss is bored with a taper hole, and receives the taper revolving hollow
spindle which carries the Governor balla.
The hollow spindle is provided with a gut pulley by which it is driven, and
contains a spiral sping adjustable by a nut, and reacting upon the governor arms,
through a central spindle, which is connected to the valve by a revolving union
joint.
This arrangement of governor allows the point of suspension of the balls to be
truly in the axis, and so ensures a more perfect and sensitive action than in those
governors, the suspension of whose arms is on either side of the axis.
With the before specified parts I combine the remaining details of a horizontal
engine which are known and therefore do not require to be particularly specified.

We, WILLIAM ROBERTSON, of 31, Lombard Street in the City of London,
Merchant, and GEORGE ABRAHAM GOODWIN, formerly of Fenchurch House,
Fenchurch 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 HORIZONTAL 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 class of steam engine known as 'horizontal, and'
consists of improvements in construction whereby the engine is rendered more
compact in arrangement, more effective, 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 side elevation of our improved engine.
Figure 2 an end elevation of our engine with a modified form of throttle valve.
Figure 3 is a plan of our improved horizontal engine.
Figure 4 is a detail of the governors.
Figure 5 shows the arrangement of cylinder for long stroke engines.
The cylinder, A, and guides, B, are cast together in one piece, the guides being
circular in section, so that the working faces of the cross-head slides may be bored.
The lower portion of the guides have two feet or flanges, b, for attachment to
the bed plate, O, the cylinder overhanging in short stroke engines and being solid
as aforesaid with the circular end of the guides which forms the front cover.
Where the engines are of longer stroke, as shown in figure 5 these flanges or feet
are carried along the sides of the cylinder as well as the guides, and the bed is
elongated to receive them, and to which it is bolted, the piston rod being carried
through the back cover in a dummy gland.
The valve spindle guide, D, may be cast in one piece with the cylinder, or
separately attached to the bed plate as shown.
We provide the cross-head with loose slippers, E, of cast iron, gun metal, or other
material, turned on their external circumference, so as to fit the bored surface of
the guides, and the slippers are formed so as to permit of packing being placed
between them and the cross-head when necessary.
The bed plate, C, is widened at the crank end, so as to carry the two main crank
bearings, F, F, which are cast with the frame conveniently at an angle of 45°, and
the bed plate is dished out between the bearings to admit of the play of the crank.
The governor is of the high speed type and is preferably suspended, instead of
being supported from below.
It is constructed as follows, as shown in sectional detail (figure 4).
. The body, G, forms a combined throttle and stop valve, operated by the governor
spindle, g, and by the screw down handle, H, respectively. The valve, h, is of the
piston type, working over two or more grids. The bottom flange of 'the valve
casing is provided with a cover, K, and stuffing box and gland, k. This cover has
cast on with it a hemispherical hood, L, with a boss, at its lower extremity.

page_text: This boss is bored with a taper hole and receives the taper revolving hollow
spindle, M, which carries the governor balls.
This hollow spindle is provided with a gut pulley, N, by which it is driven, and
contains a spiral spring, n, adjustable by a nut, n¹, and reacting against the
.centrifugal action of the governor balls, P, through a central spindle, g, which is
connected to the valve by a revolving union joint.
This arrangement of governor allows the point of suspension of the balls to be
truly in the axis, 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 governor may be caused to operate the throttle valve, placed within the steam
chest as at Figure 2, the governor spindle being connected to the valve by a rod
passing into the steam chest through a gland and controlling the steam supply by
a rotative reciprocating movement of the said throttle valve round the rod.
With the before specified parts I combine the remaining details of a horizontal
engine which are known, and which therefore do not require to be particularly
specified.
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 horizontal engine consisting of a combination of the
usual known parts with bored guides and cylinder cast therewith, the piston rod
being provided with a cross head fitted with adjustable slippers for taking up the
wear, and the cylinder steam pipe provided with a combined stop and throttle
valve, operated by a high speed governor, substantially as described.
2nd In such a horizontal engine the construction of the high speed governor
consisting of the governor arms suspended from a single pin in the true axis of
rotation, the revolving governor spindle being supported above the governor balls
upon a cone seating, an adjustable spiral spring reacting against the centrifugal
action of the governor balla, substantially as described in reference to figure 4.
