We RALPH PEACOCK and HERMANN LUDWIG LANGE both of Gorton Foundry
Manchester in the County of Lancaster Engineers do hereby declare the nature of
this invention to be as follows:-
•
This invention has for its object to effect the connection and transmission of
the motive power as required without the intervention of toothed, rope, chain,
friction, or other gearing; and consists in connecting the shaft, or shafts, of the
armature, or armatures, of the motor to the driven axle, or axles, of the locomotive,
or road, engine by means of cranks and a connecting rod or connecting rods or the
armature shaft or shafts may be connected by means of cranks and a connecting rod
or rods to an intermediate axle or axles and from them connection be made by means
of cranks and a connecting rod or rods to one or more of the driven axles of
the locomotive or road engine. The axle box guides are so placed as to permit the
vertical movement of the axle boxes to be at right angles to the central line of the
armature shaft or shafts and the driven axle or axles or the armature shaft or shafts
may be supported by a frame carried on bearings on the driven or the carrying axles
of the locomotive or road engine.

COMPLETE SPECIFICATION (AMENDED).
Improvements in or connected with Locomotive Engines or
Vehicles Driven by Electric Motors.
We, RALPH PEACOCK, and HERMANN LUDWIG LANGE, both of Gorton Foundry,
Manchester, in the County of Lancaster, Engineers, 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 locomotive, or road engines, or vehicles driven by electric
motors; and has for its object to effect the connection and transmission of the motive
power as required without the intervention of toothed, rope, chain, friction, or other,
gearing, and consists in connecting the shaft of the armature, or shafts of the
armatures, of the motor, to the driven axle, or axles, by means of cranks and con-
necting rods or the armature shaft, or shafts, may be connected by means of oranks
and connecting rods to an intermediate shaft, or shafts, and from them connection be
made, by means of cranks and connecting rods, to one, or more, of the driven axles.
The the axle box guides are preferably being so placed as to permit the movement of the
axle boxes of the driven axle, or axles, to be at right angles to the central line of
the armature shaft, or shafts, and the driven axle, or axles, and the armature shaft,
or shafts, may be supported by the same frame, or the driven axle, or axles, may be
supported by one frame, and the armature axle, or axles, be supported by another'
frame carried by the driven, or carrying, axles.

page_text: And in order that this invention may be well understood we will now proceed to
describe the system, mode, or manner, in, or under which, the same may be
carried into effect reference being had to the accompanying drawings, whereon
the same letters of reference are employed to denote the same parts in all the
figures.
Figure 1 is a side elevation and Figure 3 a half plan of so much of a locomotive,
or road engine as is necessary to illustrate the application of our invention thereto,
with the axles of the armature and of the driven, or carrying, wheels supported in the
same frame. Figure 2 shews an axle box inclined, as hereinbefore described, and as
shewn in Figure 1, but with the bearing spring also inclined. Figure 4 is a side
elevation, and Figure 5 a half plan, of n locomotive, or road, engine with armature
shafts-supported by a frame independent of the main frame which supports the driven,
or carrying, axles. It will be understood that the parts shewn in Figures and 5 are
duplicated in the half not shewn.
A, are the armature shafts, and B, are the cranks on the said shafts, to the pins b
of which cranks one of the ends of each of the connecting rods C, is connected, the
other ends of the said connecting rods being connected to the crank pins E, of the
wheels on the driven axles D, or to crank pins on cranks secured to the said axles.
F, is the main frame which, in the-arrangement Figures 1 and 3, carries the axles A,
and D, whilst in Figures 4 and 5 it carries only the axles D, the axles A being in
supplementary frames-K, supported by the carrying axles D, as-shewn. G are the
axle boxes working in the axle box guides, or horns, H, these being arranged, as
shewn, so that they are in the inclined position as, and for the purpose, herein-
before mentioned. II are the bearing springs, which may be arranged either as
shewn in Figure 1, or at an angle corresponding to that of the axle boxes, as shown
in Figure 2. In the arrangement Figures 4 and 5, owing to the axles A being on a
separate frame, the axle boxes may be in the ordinary position shown. It is preferred
that the cranks B shall be counterweighted, as shewn at 6².
It will be understood that, instead of using the inclined connecting rods-C, the
connection of the axles A, with the axles D, may be made indirectly by connecting,
by means of connecting rods, the cranks of the axles A to cranks on intermediate
shafts, which are in turn connected, by connecting rods, to the crank pins E; but
this would only be resorted to in exceptional-eases where it might be necessary to
avoid parts with which the inclined rods C, might interfere. We, of course, prefer,
in all cases where practicable, to use the simple and direct connection by means of
the inclined connecting rods C.
In the arrrangement according to our invention there may be any desired number
of motors and driven, or carrying, axles; for instance, there may be two sets of
motors and driven axles, that is four motors and four carrying axles, in which case,
where the vehicle is to run round curves one set of the motors and driven axles may
be supported in a bogie connected to the main frame, so that the said set can turn,
independently of the main frame, to meet the necessities of such curves. Or each
set of motors and driven axles may be mounted on a bogie connected to the main
frame.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. In locomotive engines, or vehicles, driven by electric motors; connecting the
chaft, or-shafts, of the armature, or armatures, of the motor to the driven axle, or
axles, by means of cranks and connecting rods; substantially as hereinbefore
deseribed.
chait, or shafts, of the armature, or armatures, of the motor to the driven axle, or
axles, by means of cranks and connecting rods; substantially as hereinbefore
described.
2. In focomotive engines, or rehicles, driven by cheeric motors, connecting the
shaft, or shafts, of the armature, or armatures, of the motor directly to the driven axle,
or axles, by means of cranks and diagonally disposed connecting rods; substantially
as herein before described and shewn in the accompanying drawings.
3. In locomotive engines, or vehicles, driven by electric motors; connecting the

page_text: shaft, or shafts, of the armature, or armatures, of the motor, directly to the driven
axle, or axles, by means of cranks and diagonally disposed connecting rods, in
combination with axle boxes and guides, or horns, situated in an inclined position;
substantially as, and for the purpose, hereinbefore described, and illustrated.
4. In locomotive engines, or vehieles, driven by electric motors; connecting the
shaft, or shafts, of the armature, or armatures, of the motor to the driven axle, or axles,
by means of cranks and connecting rods; the shaft, or shafts, of the armature, or
armatures, being supported in a frame independent of the main frame; substantially
as hereinbefore described.
