PROVISIONAL SPECIFICATION.
Improvements in Traction or like Locomotive Engines.
We, FREDERICK SAVAGE of St. Nicholas Works, King's Lynn in the County
of Norfolk Engineer and CHARLES GRAY Rix of the same place Draughtsman,
do hereby declare the nature of our invention to be as follows:
The object of this invention is to provide simple and efficient means whereby
springs can be very advantageously applied to traction and like locomotive
engines.
According to this invention the axle of the hind wheels is carried by bearings
which can slide vertically in guides attached to the horn plates or side frames of
the engine the horn plates or frames resting on a spring, or springs, which may be
blade springs, connected by a strap, or carrier with cross pieces, which extend
across from one side to the other, their outer ends resting on or engaging with
rests, or catches, formed on, or connected to, the said bearings. The intermediate
shaft by means of which, through suitable gearing, motion is conveyed from the
crank shaft, to the axle of the hind wheels, is carried in bearings capable of sliding
in guides attached to the horn plates or side frames of the engine the said bearings
being connected by pins and links with the bearings of the axle of the hind
wheels. The gearing wheel or wheels by which motion is transmitted from the
crank shaft (and thence through the intermediate shaft to the hind wheels) is
mounted in a circular boss secured to the horn plate or side frame the con-
nection between the intermediate shaft and toothed wheel being effected by
making a transverse piece on the end of the said shaft to slide in a slot in a
piece which has projections at right angles to the said slot which can slide
between guides projecting inwards from the interior of the boss of the gear
wheel. The other end of the said intermediate shaft carries a pinion for
driving the axle of the hind wheels. By this arrangement the bearings of the
axle of the hind wheels and of the intermediate shaft can move relatively to
the body of the vehicle so that the springs can act to relieve strain and
vibration when the vehicle meets obstacles which cause the springs to come into
action.

Improvements in Traction or like Locomotive Engines.
We, FREDERICK SAVAGE, of St. Nicholas Works, King's Lynn, in the County
of Norfolk, Engineer, and CHARLES GRAY RIX, of the same place, Draughtsman,
do hereby declare the nature of this invention, and in what manner the same is to
be perforined, to be particularly described and ascertained in and by the
following statement :—
The object of this invention is to provide simple and efficient means whereby
springs can be very advantageously applied to traction and like locomotive
engines.

page_text: The invention will be best understood by reference to the accompanying drawings
in which
Figure 1 is an end elevation, partly in section, of as much of a traction engine as
is necessary to illustrate the application of this invention thereto, and,
Figure 2 is a side elevation of Figure 1 with certain portions removed and others
shewn in section.
According to this invention the axle A of the hind wheels B is carried by
bearings C which can slide vertically in guides D attached to the horn plates, or
side frames, E, of the engine, the said horn plates or side frames or the guides D
(as shewn in the drawings) resting on a spring or on springs F which may
conveniently be blade springs, as represented. The springs F, of which two are
shewn in the drawings are connected by a strap or carrier F¹ and bar 52 with a
cross bar or cross bars G which extends or extend across from one bearing C to
the other, its or their outer ends resting on, or engaging with, shoulders or
projections C formed on, or secured to, the bearings C.
The intermediate shaft H by means of which, through suitable gearing (as for
example the double spur wheel I and spur pinion J¹ or .³) motion is conveyed from
the crank shaft J to the axle A, is carried in bearings K capable of sliding in
guides D' attached to the horn plates or side frames E, these bearings K being
connected by links L and pins L' with the bearings C.
The double spur wheel I is provided with a large hollow boss I¹ adapted to
rotate in a circular boss or bearing M secured to one of the horn plates or side
frames E. The connection between the wheel I and the intermediate shaft H is
effected by means of a transverse piece or T-head H' on one end of this shaft
engaging with, and free to slide in, a slot N¹ in a piece or frame N which is
provided with projections N2 at right angles to the slot N', these projections N³
engaging with, and being free to slide between, guides 12 projecting inwards from
the interior of the wheel boss I¹. On the other end of the intermediate shaft H is
secured a spur pinion H' which, through a spur wheel A¹ drives the road-wheel
axle A in the usual manner.
By the foregoing arrangement the bearings C and K are free to move relatively
to the body of the vehicle so that the spring or springs F can act to relieve strain
and vibration when the vehicle meets obstacles which cause the said spring or
springs to come into action.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a traction or like locomotive engine the combination with the intermediate
shaft for transmitting motion from the crank-shaft to the road-wheel axle, of a
transverse piece or "-head such as H thereon, a frame such as N having a slot N¹
and projections Nº, and a spur-wheel having a hollow boss such as I provided
with guides I substantially as hereinbefore described with reference to the
accompanying drawings.
2. In a traction or like locomotive engine the combination with bearings for the
axle of the hind road wheels capable of sliding in guides in the horn plates or
guides of a cross bar or cross-bars such as G connected to a spring or springs such
as F so as to act substantially as herein before described with reference to the
accompanying drawings.
3. In a traction or like locomotive engine the combination and arrangement of
parts constituting the complete driving and spring-suspension apparatus substan-
tially as hereinbefore described and illustrated in the accompanying drawings.
