PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Railway Rails..
I, RICHARD LEOPOLD KIRLEW of Whittall Street, Birmingham in the County.
of Warwickshire Commercial Traveller, do hereby declare the nature of. this
invention to be as follows:-
This invention relates to the manufacture of rails or railway bars, particularly to
the forms of railway bars that require the web between the upper and lower heads,
or between the head and the lower flange at each end of said railway bars to be
thicker than the web in the other or central portions of bar.
}₁.
The object of this invention is to effect the thickening of the web at the ends of
the railway bar by means hereinafter described, said thickening or filling up being
unable to be performed during the operation of rolling or until after the railway bar
has left the rolls.
In this invention I lap round the required length of the end of a railway bar,
which may be either of the double headed, or the T sectional form, a coil of iron or
steel I heat the pile thus formed at the end of the railway bar in a furnace and
then place said end between dies under a steam or drop hammer, or in a hydraulic
press. By these means the ends of railway bars may be thickened so as to be
capable of being cut or shaped to fit one over the other, or as required, or they may
be scarved at one operation.
Dated this 7th day of March 1892.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Railway Rails.
I, RICHARD LEOPOLD KIRLEW of Whittall Street, Birmingham, in the County
of Warwickshire, Commercial Traveller, 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 manufacture of rails or railway bars, particularly to
the forms of railway rails that require the web between the upper and lower heads,
or between the head and the lower flange at each end of said railway rails to be
thicker than the web in the other or central portions of rail.
The object of this invention is to effect the thickening of the web at the ends of
the railway rail by means hereinafter described, said thickening or filling up being
unable to be performed during the operation of rolling or until after the railway rail
has left the rolls.
In this invention I lap round the required length of the end of a railway rail
which may be either of the double headed or the T sectional form a coil of iron or
steel I heat the pile thus formed at the end of the railway rail in a furnace and
then place said end between dies under a steam or drop hammer or in a hydraulic
press. By these means the ends of railway rails may be thickened so as to be
capable of being cut or shaped to fit one over the other or as required or they may
be scarved at one operation, either in the forms such as are represented in the
accompanying sheet of drawings or in like manner.
For the purpose of allowing for contraction and expansion, the holes for the bolts
may be elongated.

page_text: Fig. 1 is a side view of a rail end and
Fig. 2 is an end view of the same.
Figs. 3 and 4 are side views of rail ends showing other, forms of scarving.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
For scarving the ends of railway rails either in the form shown on the accom-
panying drawing, or other form in which the rail ends require to be thickened, the
means employed for filling up or increasing the thickness of the web of said railway
rail in the manner substantially as herein before described.
