Improved Crosshead and Connecting Rod Gear for Locomotive
Engines.
I, CHARLES DENTON ABEL, of No. 28 Southampton Buildings, Chancery Lane, in
the County of London, Consulting Engineer and Patent Agent, do hereby declare
the nature of this invention to be as follows:-
--
This invention relates to an improved construction of cross head and connecting
rod gear for the steam cylinders of locomotive engines wherein, in place of connecting
the crosshead by a single connecting rod to one of the engine wheels and thien
coupling such wheel by coupling rods to ono or more other wheels as heretofore, the
crosshead is adapted to be combined with two or more connecting rods for connection
with two or more wheels so as to drive these directly instead of through coupling rods,
when for some reason, such coupling rods cannot be conveniently used. The wheels
so connected may either be the running wheels of an ordinary locomotive engine, or the
toothed wheels of an engine running on a rack railway. In this construction of
engine, to which the invention is more particularly applicable in order that the axles
of the ordinary bearing wheels may not interfere with the driving gear of the toothed
wheels, the crosshead of the piston rod may be extended in length, so that there
may be a connection to the connecting rod for the nearest toothed wheel at the part
of the crosshead nearest the cylinder, and another connection or connections to the con-
necting rod or rods for the second or other toothed wheel or wheels at a point or points
correspondingly distant from the first named connection, so that the connecting
rods will then work more or less parallel with each other. The guides for the cross-
head are arranged in any suitable manner for affording the propor support to the
crosshead at the several points of connection. The crossheads may also be arranged
so that the several connecting rods are connected thereto at equal distances from the
piston, and they may even be connected to one and the same pin on the crosshead,
this being either arranged to work between two guide bars, or being formed with a
sleeve sliding on a single guide bar.

I, CHARLES DENTON ABEL of No. 28 Southampton Buildings, Chancery Lane, in
the County of London, Consulting Engineer and Patent Agent, 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 to an improved construction of crosshead and connecting rod
gear for the steam cylinders of locomotive engines wherein, in place of connecting
the crosshead by a single connecting rod to one of the engine wheels and then
coupling such wheel by coupling rods to one or more other wheels as heretofore, the
crosshead is adapted to be combined with two or more connecting rods for connection
with two or more wheels, so as to drive these directly instead of through coupling
rods, when for some reason such coupling rods cannot be conveniently used. The
wheels so connected may either be the running wheels of an ordinary locomotive
engine, or the toothed wheels of an engine running on a rack railway.

page_text: The above described crossheads may be constructed either as shown at Figs. 1. and 2,
where the connecting rods A A¹ are pivotted either close together on the cross-head B
as at Fig. 1 or to one and the same pin as at Fig. 2, or the crosshead B may be
formed with an extension, as at Fig. 3, which shews by way of example the application
of the invention to a combined adhesion- and rack-locomotives.
In this case the crosshead B is extended forward to such an extent as to bring the
second connecting rod A' into a position in which it will drive the second
toothed wheel for the rack rail without interfering with the axle of the intermediate
pair of bearing wheels.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what I
claim is :-
In locomotive engines, the combination of one cross-head with two or more con-
necting rods, substantially as and for the purpose herein set forth.
Dated this 29th day of August 1889.
