PROVISIONAL SPECIFICATION.
New Method of Utilizing Old Rails.
ANDREW ERSKINE MUIRHEAD Forgeman Cart Forge Crossmyloof Glasgow.
hereby declare the nature of this invention to be as follows:-
I take an old double headed or bull headed section rail and cut it into suitable
lengths say about a foot long. I then heat those pieces and stamp them into a
suitable die.
I then proceed to slit and finish said blanks as described in my Specifications 19656
of 1894 22669 of 1895 thus forming a railway chair.
Dated this 24th day of June 1896.

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:-
I take an old double-headed or bull-headed section rail, and cut it into suitable
lengths of, say, about a foot.
I then heat those pieces, and place them on a suitable die, so that the rail flanges
lie along, and fill the recesses of die, into which they are stamped, said stamping
taking the form represented in the accompanying drawing by Figures 3 and 4.
I then proceed to slit and finish said blanks or stampings in the manner described
in my Specifications, No. 19656, 1894, and No. 22669, 1895, thus forming a railway
chair.
By utilizing the flanges of old rail to fill the recesses of die, I form the projections
or ridges required to form the lugs of chair, when slit and bent up.
The die has its recesses arranged in distance apart co-inciding, or nearly so, with
the distance apart of the two flanges of old rail.
With pot chairs I take a proportionately greater length of old rail, thus giving
myself a necessary increase of material in the bending or dishing of base of chair.
With sleeper and chairs combined I make the rail section of such a length that I
can stamp a chair on each end, and when the middle of said stamping may be flattened,
dished or left untouched. They are slit and bent up in the same way as the chair
above described.
Although I have hereinbefore described and shown billet such as I use for a
double-headed rail chair, it must be understood that I do not confine myself to this
form of chair only.
I will now proceed to describe, with reference to the accompanying drawings, the
manner in which my invention is to be performed.

Figure 2 represents section of die on line B', B; dotted line representing section of
rail in position for stamping.
Figure 2 represents plan of die.
Figure 3 represents edge view of stamping.
Figure 4 represents plan of same stamping.
Figures 3 and 4 are suitable both for double-headed and bull-headed section rails.
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 :-
The using of old rails as billets in the manufacture of my railway chairs, and railway
sleeper with chairs combined.
Dated this Twenty-fourth day of March 1897.
