PROVISIONAL SPECIFICATION.
Improvements in Railway and similar Vehicles.
I, SAMSON Fox, of The Leeds Forge, New Wortley, Leeds, in the County of
York, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction of the underframes of four or six wheeled
railway and similar vehicles in such a manner that the sides or solebars are assisted
in carrying the ultimate load by other members of the framing; and that the
spacing or distance between the solebars can be made of any desired width irrespec-
tive of the limits usually imposed by the distance apart of the centres of journals of
the axles, thus admitting of an increase in the width of a vehicle body without the
need of supplementary side bars, sometimes called rocker bars, or of brackets to
support them, or the bottom sides of a body, to make up the required width of the
vehicle when such body exceeds in width the dimensions between or outside of the
solebars limited by the distance apart between the centres of journals as above
mentioned.
In constructing underframes according to this invention, I employ according to
one arrangement cross bearers or bars to carry the ultimate load and to them I
attach the solebars and some of the principal members of the underframe, and when
necessary spacing them apart to any convenient width to bear on or receive the
attachments to the ends of the bearing springs.
In another arrangement I utilize the extreme cross beam or headstock to directly
support a portion of the ultimate load, either directly, or by means of a longitudinal
member connecting the headstock and another cross member of the underframe, as
the necessities of construction may require.
In another arrangement I transmit and distribute the ultimate load bearing on
the axle journals through the medium of the axle guards; sometimes called horn
plates, on which I provide suitable attachments for receiving the bearing springs,
laminated or spiral, as the case may need, the axle guards being secured to the
members of the underframe in any suitable manner.
In a further arrangement I distribute the ultimate load directly amongst other
members such as the longitudinals and diagonals, etc., of a vehicle underframe,
sometimes placing the members parallel to the solebars and connecting them by
cross bearers, and utilizing the axle guards or horn plates for distributing the
ultimate load in a similar manner to that described in the last mentioned arrange-
ment.

COMPLETE SPECIFICATION.
Improvements in Railway and similar Vehicles.
I, SAMSON Fox, of The Leeds Forge, New Wortley, Leeds, in the County of
York, Civil 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:-
This invention relates to the construction of the underframes of four and six
wheeled railway and similar vehicles in such a manner that the sides or solebars are

page_text: assisted in carrying the ultimate load by other members of the framing, and that
the spacing or distance between the solebars can be made of any desired width
irrespective of the limits usually imposed by the distance apart, in a transverse
direction, of the centres of journals of the axles, thus admitting of an increase in the
width of a vehicle body without the need of supplementary side bars, sometimes
called rocker bars, or of brackets to support them or the bottom sides of a vehicle
body, to make up the required width of the vehicle when such body exceeds in
width the dimensions between or outside of the solebars, limited by the distance
apart between the centres of journals as above mentioned.
In the accompanying drawings,
Figs. 1, 2 and 3 are side, plan and end views respectively illustrating one
construction of underframe according to this invention suitable for a four wheeled
vehicle.
In this construction the sole-bars 1, are attached to two pairs of cross bearers or
bars 2 to which are attached some of the principal stiffening members 3 of the
underframe and which are spaced a convenient distance apart by longitudinal
members 4 to receive the attachments 5 to which the ends of the bearing springs 6
are connected. By this construction it will be seen that the weight of the body of
the vehicle instead of being taken by and transmitted directly through the two sole-
bars to the springs and thence to the axle journals 7 as heretofore, is distributed
over and taken by the pair of sole-bars and two pairs of cross bearers through which
latter the ultimate load is transmitted to the springs, so that the sole-bars can be
made of lighter sections than usual and can be placed at any suitable distance
apart to suit requirement, without reference to the distance apart in a transverse
direction, of the centres of the journal bearings, and without the use of supple-
mentary side bars or brackets as hereinbefore mentioned.
Fig. 4 shows partly in side elevation and partly in longitudinal section ;
Fig. 5 shows partly in plan and partly in horizontal section; and
Fig. 6 shows partly in end elevation and partly in cross section, and to a larger
scale another construction of underframe, in which the two extreme cross beams or
headstocks 2* are utilized in conjunction with the sole-bars 1 and cross bearers 2 to
directly support the ultimate load and transmit it to the bearing spring 6 either
directly as by attachments 5 in the manner shown in Figs. 1, 2 and 3, or by means
of longitudinal members 4 which may, as shown, be in the form of horn plates or
axle guards (hereinafter called horn plates) some of which, viz. the end ones,
connect the headstocks 2ª with the adjacent cross bearer 2.
In this example the underframe is shown as constructed for a six wheeled vehicle
for which purpose the horn plates 4 for the intermediate axle are suitably secured
between the two cross bearers. Each horn plate or axle guard is provided with
suitable attachments for the corresponding bearing spring 6. For a four wheeled
vehicle, the intermediate horn plates 4 would be dispensed with, the cross bearers 2
being then stiffened by suitable means such as longitudinal stiffening members
similar to the other longitudinal stiffening members 3. In either case the ultimate
load is transmitted as in the previous case through two pairs of comparatively
short cross bearers and headstocks, instead of through one pair of comparatively
long sole-bars.
Fige. 7, 8 and 9 are similar views to Figs. 4 5 and 6, respectively illustrating
another construction of under frame according to this invention suitable for a four
wheeled vehicle.
In this arrangement the ultimate load is taken, as in the first described arrange-
ment, by the pair of sole-bars 1 and two pairs of cross bearers 2 which are suitably
connected and strengthened by other bars 3 and plates 3ª but the said load is
transmitted through the said cross bearers to the axle journals through the medium
of horn plates 4 which, as in the last described arrangement, are provided with
suitable attachments for receiving the bearing springs. These springs, in each 5
case, may be of any suitable kind, such as laminated or spiral springs, as may be
desired. The horn plates in the example now being described, as well as those.

page_text: shown in the last described arrangement are made of pressed metal of the form
shown, and are each secured, in any suitable manner, between two of the cross
bearers 2, or between a cross beam and a headstock, as the case may be, the bearing
springs 6 being of laminated form and each connected to the corresponding horn
plate by suitable attachments 5.
Figs. 10, 11 and 12 are similar views to Figs. 1, 2 and 3 respectively, illustrating
a further modified construction of underframe in which the weight of the body of
the vehicle and its contents is distributed amongst other members of the under-
frame such as the longitudinals 8 which are secured to the headstocks 2* and
connected to the sole-bars 1, with which they are parallel, by several pairs of short
cross bearers 2 which transmit the ultimate load to the springs 6 through the
attachments 5 and thus to the axle journals.
By my invention not only can the sole-bars be spaced at any desired distance
apart to suit circumstances, and supplementary side bars or brackets be dispensed
with, but the various members of the underframe can be made of much lighter
sections than heretofore, so that the total weight of the underframe necessary for a
vehicle of a given size can be considerably reduced as compared with the under-
frame necessary for a similar vehicle, as heretofore constructed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction of the underframes of railway and similar vehicles in such
a manner that the sides or sole-bars are assisted in carrying the ultimate load by
other members of the underframes so that the spacing or distance apart of the
sides or sole-bars can be made of any desired width irrespective of the limits
usually imposed by the distance apart, in a transverse direction, of the centres of
the axle journals, substantially as hereinbefore described for the purposes specified.
2. The construction of the underframes of railway and similar vehicles
substantially as hereinbefore described and illustrated in Figs. 1, 2 and 3 of the
drawings annexed.
3. The construction of the underframes of railway and similar vehicles
substantially as hereinbefore described and illustrated in Figs. 4 5 and 6 of the
drawings annexed.
4. The construction of the underframes of railway and similar vehicles
substantially as hereinbefore described and illustrated in Figs. 7, 8 and 9 of the
drawings annexed.
5. The construction of the underframes of railway and similar vehicles
substantially as hereinbefore described and illustrated in Figs. 10, 11 and 12 of the
drawings annexed.
Dated this 20th day of October 1893.
