PROVISIONAL SPECIFICATION.
Improvements in the Manufacture or Construction of Equalizing
Beams or Bars for Rolling Stock.
I, SAMSON FOX, of the Leeds Forge, Leeds, in the County of York, Engineer
and Iron Master, do hereby declare the nature of this invention to be as
follows:-
My present invention has reference to improvements in the construction of
equalizing beams or bars for rolling stock of the kind forming the subject of my
application for Letters Patent No. 1019 dated (under the International Convention)
7th November 1890.
In the Specification of that application I described a pressed steel equalizing
beam or bar made of channel form in cross section, and bent upward and outward
at its two ends; and my present invention has reference to the combination with
such an equalizing beam or bar of additional strengthening devices as hereinafter
explained with reference to the accompanying sheet of illustrative drawings the
object being to strengthen the requisite parts without having to form beads at the
sides of the channelled beam.
In the drawings,
Fig. 1 is a side elevation of my improved beam.
Fig. 2 is a half longitudinal section to a larger scale.
Fig. 3 is a cross section at A A Fig. 2.
Fig. 4 is a cross section at C. C. Fig. 2.
Fig. 5 is a cross section at B. B. Fig. 2.
As before the beam is made from a flat plate preferably of steel pressed whilst
hot to a channelled form (see Figs. 3, 4, and 5) between male and female dies and
simultaneously bent into approximately the shape represented in Fig. 1, which
however shews the beam made of varying depth in cross section, not of uniform
section as represented in the drawings accompanying my other application for
Letters Patent hereinabove referred to.
For the purpose of stiffening the beam laterally I provide at intervals in the
channel between the walls thereof, distance tubes 1 and rivets 2 that pass through
holes in the walls of the channel and through the distance tubes thereby firmly
tying the walls and maintaining them at the proper distance apart. In order to
strengthen the beam at the bends which join the central portion to the rising parts,
I there provide internal bent strengthening pieces 3 of channel form in cross section,
and having the channel mouths thereof reversely arranged to that of the beam
itself as represented in Fig. 5. Holes are formed through the walls of the beain
channel and of the inserted channelled strengthening piece; within this piece
distance tubes 4 are placed, and rivets 5 effectually tie and hold the whole
together.
For the purpose of imparting additional strength to the shallower ends and the
bent portions that unite the same to the rising portions of the beam, I provide
at these parts internal channelled strengthening pieces 3 and also external channelled
strengthening pieces 6; through the walls of these and of the beam itself rivet holes
are formed; within the internal channelled strengthening pieces distance tubes are
placed; and through the whole rivets 5 are passed whereby the several parts are
firmly held together.
Dated this 20th day of January 1891.

Improvements in the Manufacture or Construction of Equalizing
Beams or Bars for Rolling Stock.
I, SAMSON Fox of the Leeds Forge, Leeds, in the County of York, Engineer
and Iron Master, 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 :-
My present invention has reference to improvements in the construction of
equalizing beams or bars for rolling stock of the kind forming the subject of my
application for Letters Patent No. 1019 dated (under the International Convention)
7th November 1890.
In the Specification of that application I described a pressed steel equalizing
beam or bar made of channel form in cross section, and bent upward and outward
at its two ends; and my present invention has reference to the combination with
such an equalizing beam or bar of additional strengthening devices as hereinafter
explained with reference to the sheet of illustrative drawings left with my
Provisional Specification the object being to strengthen the requisite parts without
having to form beads at the sides of the channelled beam.
In the drawings,
Fig. 1 is a side elevation of my improved beam.
Fig. 2 is a half longitudinal section to a larger scale..
Fig. 3 is a cross section at A A Fig. 2.
Fig. 4 is a cross section at CC Fig. 2.
Fig. 5 is a cross section at B. B. Fig. 2.
As before the beam is made from a flat plate preferably of steel pressed whilst
hot to a channelled form (see Figs. 3, 4 and 5) between male and female dies and
simultaneously bent into approximately the shape represented in Fig. 1, which
however shews the beam made of varying depth in cross section, not of uniform
section as represented in the drawings accompanying my other application for
Letters Patent hereinabove referred to.
For the purpose of stiffening the beam laterally I provide at intervals in the
channel between the walls thereof, distance tubes 1 and rivets 2 that pass through
holes in the walls of the channel and through the distance tubes thereby firmly
tying the walls and maintaining them at the proper distance apart. In order to
strengthen the beam at the bends which join the central portion to the rising parts,
I there provide internal bent strengthening pieces 3 of channel form in cross
section, and having the channel mouths thereof reversely arranged to that of the
beam itself as represented in Fig. 5. These strengthening pieces may be made.
solid if desired, but I prefer to make them as described. Holes are formed through
the walls of the beam channel and of the inserted channelled strengthening piece;
within this piece distance tubes 4 are placed, and rivets 5 effectually tie and hold
the whole together.
For the purpose of imparting additional strength to the shallower ends and the
bent portions that unite the same to the rising portions of the beam, I provide at
these parts internal channelled strengthening pieces 3 and also external channelled
strengthening pieces 6; through the walls of these and of the beam itself rivet
holes are formed; within the internal channelied strengthening pieces distance tubes
are placed; and through the whole rivets 5 are passed whereby the several parts
are firmly held together.
I do not limit myself to the exact design of equalizing bar described, which may
be varied to suit requirements.

page_text: 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 :-
:-
The hereinabove described improved manufacture or construction of equalizing
beams or bars for rolling stock, wherein a piece of metal pressed to a channel form
in cross section and bent upward and outward at its two ends has combined with it
additional strengthening devices such as hereinabove described with reference to
and shown in the drawings annexed for the purpose specified.
Dated this 8th day of October 1891.
