PROVISIONAL SPECIFICATION.
Improvements in the Construction of Underframes of Railway and
other Rolling Stock.
I, SAMSON Fox, of the Leeds Forge, New Wortley, Leeds, in the County of
York, Engineer and Ironmaster, do hereby declare the nature of this invention to
be as follows:-
The underframes of railway and other rolling stock such as used on tramways and
common roads are ordinarily constructed of a combination of timber and metal work
and are generally heavy in order to obtain the necessary strength and rigidity and
are usually rather costly.
My present invention has reference to such underframes as are constructed of
ordinary channel iron or steel and relates to a method of forming and strengthening
those parts whereby the various portions of such underframing are joined together.
For this purpose I take ordinary channel iron or steel of suitable length to form
the respectively required part or parts, heat the ends thereof and place it on a suitable
die or mandrel, and by means of specially prepared tools actuated by hydraulic or
other means one or both of these ends is or are pressed or turned to a right or other
angle with the other part in suchwise as to form a solid end or ends thereto, thus
dispensing with separate pieces for effecting the junction of the several parts com-
prising a complete underframe.
This process can also be employed in forming solid angular ends to tee or angle
iron or steel or other. section of bars.

COMPLETE SPECIFICATION.
Improvements in the Construction of Underframes of Railway and
other Rolling Stock.
I, SAMSON Fox, of the Leeds Forge, New Wortley, Leeds, in the County of
York, Engineer and Ironmaster, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
The underframes of railway and other rolling stock such as are used on tramways
and common roads are ordinarily constructed of a combination of timber and metal
work and are generally made heavy in order to obtain the necessary strength and
rigidity and are usually somewhat costly.
Sometimes however such underframes are constructed of ordinary channel iron or
steel with the end attachments made by rivets or by cutting and welding the end of
the bars and my present invention relates to a method of manufacture and in particular
to a way of forming a solid end on channel bars for the purpose of strengthening those
parts and forming a convenient method of joining the various portions of such under-
framing together.
For this purpose I take channel iron or steel of suitable length to form the
respectively required part or parts, such channels being either rolled as bars or
pressed or flanged from flat plates, heat the end or ends thereof, place the metal on a
suitable die or mandrel, and press or turn one or both of the ends to a right or other
angle with the other part in suchwise as to form a solid end or solid ends thereto,
that is to say a part or parts at the required angle or angles but in one with the
channel itself..

page_text: It is advantageous to employ for pressing or forming the ends of such channel bars
machinery or apparatus of the kind forming the subject matter of another application
by me for Letters Patent bearing even date herewith and numbered 20888, which
machinery or apparatus is not herein claimed as constituting part of my present.
invention.
And in order that the manner of carrying my invention into practical effect may
be clearly understood I now proceed to describe the same in detail with especiai
reference to examples illustrated in the drawings hereunto annexed in which
Fig. 1 (Sheet 1) is a half sectional plan, at the line A. B. of Fig. 2 of an under-
frame constructed of solid and channel bars according to my invention.
Fig. 2 (Sheet 2) is a half sectional elevation at the line (. D. of Fig. 1.
Fig. 3 is a cross section at E. F. of Fig. 1.
Fig. 4 is a cross section at G. H. of Fig. 1.
a, a, are the sole bars; b, b, the head stocks; c, c, the cross bars; d, d, the end
longitudinals; and e, e, centre longitudinals.
As will be seen all these are of channel section and each has both its ends turned
to a right angle with the bar itself, which is effected as already described by heating
the ends, then placing on a suitable mandrel or die, and by suitable tools pressing to
the required angle so as to be suitable for attachment to another component part
of the underframe dispensing with the use of separate angle pieces at the points of
connection, and dispensing also with any welding at the corners of the bar. The
several parts may be connected together by bolts or rivets. f, f, are small brackets
made of pressed plate; 9, 9, are axle guards.
Fig. 5, Sheet 3, is a half plan.
Fig. 6 Sheet 4 is a front view partly in section on the line A. B. of Fig. 5, and
Fig. 7 is a cross sectional view (on line C. D of Fig. 5) illustrating another design
of underframe wherein the sole bars a a are formed of oppositely arranged channel
bars each having its ends turned to a right angle, and the juxtaposed ends of two bars
thus formed being fitted into the head stocks 6b which are of ordinary channel iron
or steel. The cross bars cc and the centre and end longitudinals dd, and e, e, are
also composed of oppositely arranged channel iron or steel bars with ends turned to a
right angle as specified. xx are strips of plate to which the ends of the various
parts are bolted or rivetted at the junctions. y is a piece of plate riveted to the sole
bar to stiffen it.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. The herein described improvement in the construction of underframes for
railway and other rolling stock which consists in forming a solid end on bars or plates
of suitable metal such as iron or steel of channel section.
2. The construction of underframe shewn in and described with reference t
Figs. 1 to 4 inclusive of the drawings annexed, the channel bars having solid ends
formed to the required angles in the manner set forth.
3. The construction of underframe shewn in and described with reference to
Figs. 5 to 7 inclusive of the drawings annexed, the channel bars having solid ends
turned to the required angles in the manner set forth.
Dated this 23rd day of September 1890.
