PROVISIONAL SPECIFICATION.
Improvements in Locomotive Carriages.
I, GEORGE JOHNSTON, of. Mosesfield, Springburn, in the County of Lanark,
North Britain, Engineer, do hereby declare the nature of this invention to be as
follows, that is to say :-
My said invention relates to locomotive carriages or carriages in which a motor
and passenger accomodation are combined; and it has for its object to prevent
entirely or to a large extent vibration due to the motor from being communicated
to the passenger compartment.
In carrying out my invention I construct the carriage with two framings which
are separately supported, preferably with springs in each case, on the axles of the
running wheels. One framing may he within or below the other or partly within
and partly below or above the other. Thus with a horizontal arrangement of
motor mechanism or apparatus it may be carried by a framing arranged entirely
under the platform or floor of the passenger compartment, its connections with the
wheel axles being within those of the framing of the passenger compartment. In
some cases, however, more or less of the motor apparatus may extend upwards at one
end or other convenient part of the carriage. Parts of the two framings may be
almost in contact; or they may be connected by material which will transmit very
little or no vibration.

Improvements in Locomotive Carriages.
I, GEORGE JOHNSTON, of Mosesfield, Springburn, in the County of Lanark,
North Britain, Engineer, 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, that is to say :-
-
My said invention relates to locomotive carriages or carriages in which a motor
and passenger accomodation are combined; and it has for its object to prevent
entirely, or to a large extent, vibration due to the motor from being communicated
to the passenger compartment.
In carrying out my invention I construct the carriage with two framings which
are separately supported, preferably with springs in each case, on the axles of the
running wheels. One framing may be within or below the other or partly within and
partly below or above the other. Thus with a horizontal arrangement of motor
mechanism or apparatus it may be carried by a framing arranged entirely under
the platform or floor of the passenger compartment, its connections with the wheel
axles being within those of the framing of the passenger compartment. In some
cases, however, more or less of the motor apparatus may extend upwards at one
end or other convenient part of the carriage. Parts of the two framings may

page_text: be almost in contact; or they may be connected by material which will transmit
very little or no vibration.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and representing an example of the application of my
improvements.
Figure, 1, of the drawings is a sectional side elevation of a locomotive common-
road carriage, and Figure, 2, is partly an end elevation and partly a transverse
vertical section.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
In the example delineated a four-wheeled carriage body, A, with seats for
passengers is arranged to be propelled by an electro-motor, B, which is indicated
by dotted lines and which although covered by an extension, C, of the carriage
body is not in contact with or supported thereby, but is fixed on a separate frame
or platform, D. The carriage body, A, is supported by springs, E, on cross bars
or axles, F, G, the front wheels, H, being upon short axles, J, cranked and fitted
to swivel in vertical sockets at the ends of the front cross bar, F, and provided each
with a lever connected by a link, K, to one arm of a two-armed lever, L, on the
lower end of a steering spindle, M. This steering device is like what is in use with
some tricycles; but any other suitable steering device may be substituted. The
rear wheels, N, are fitted like ordinary carriage wheels on the ends of the rear
cross bar or axle, G, but each has fixed to its hub and turning with it a sprocket
wheel, P, to be acted on by a pitch chain Q, (indicated by a dotted line in Figure 1)
driven by a small sprocket wheel, R, on a transverse shaft, S, driven by spur gearing
from the electro-motor, B. The shaft, S, is carried in bearings fixed to the frame
or platform, D, upon which the electro motor is fixed; and this frame is supported
by the cross bars or axles, F, G, by springs, T, which are separate and distinct from
those, E, supporting the carriage body, A.
The providing of spring supports for the passenger-carrying part of a vehicle
separate and distinct from the part carrying motor apparatus, is obviously applicable
with locomotive carriages of various constructions and arrangements.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In a locomotive carriage in which a motor and passenger accomodation are
combined, providing for the passenger-carrying part spring supports separate and
distinct from the parts supporting the motor, substantially as and for the purposes
herein before described.
