Improvements in Railway Crossings, and in the Method of
Constructing the same.
ALFRED HUGH TYLER, 5 Crown Court Cheapside, London, Engineer, and,
THE TYLER AND ELLIS HYDRAULIC FORGING CO. LTD. 5 Crown Court,
Cheapside, London Railway Engineers do hereby declare the nature of this
invention to be as follows:-
:
This invention relates to improvements in railway crossings made according to
the Price-Williams system, and also to improvements in the method of constructing.
the same. According to the Price Williams system, the rails forming the orossing
are suitably grooved for the flanges of the wheels and as at present constructed one
of the crossing rails is carried through the crossing, while the other crossing rail,
is in two pieces one on each side of the through rail.
Now the object of this invention is the production of a grooved crossing made
from two rails only, and this object may be obtained by so bending and grooving.
the two rails, that each rail forms part of the through line, and also part of the
crossing line; or, the two rails used are halved together at the crossing, that is to
say, one of the rails has a recess on the underside, and the other rail a recess on
the upper side. The recesses are also arranged to form the grooves for the flanges
of the wheels.
The grooves and recesses in the rails may be cut out of the rail, but they are
preferably formed by forging, and the metal displaced to form the grooves and
recesses pressed back into the web of the rail, thus enabling rails of ordinary.
sections to be grooved and recessed without a corresponding loss of strength.

ALFRED HUGH TYLER 5 Crown Court, Cheapside, London Engineer, and
THE TYLER AND ELLIS HYDRAULIC FORGING Co. LTD. 5 Crown Court
Cheapside London Railway Engineers 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, which relates to improvements in railway crossings has for its
object the construction of crossings from two rails in a simpler and more efficient
manner than heretofore and comprises the manner or method of bending, grooving,
and arranging the rails used.
In crossings constructed according to the method generally adopted previous to
this invention. there were four separate rails to each crossing and these were cut,
bent, and fixed according to the crossing required.

page_text: GUIS INYOUCion cach crossing 18 made from two rails of any
convenient length and of any ordinary section. These rails are bent and grooved
according to the position the crossing is to be placed in on the line, and also
according to the particular kind of crossing adopted.
In the accompanying drawings
Fig. 1 is the plan of an acute crossing
Fig. 2 is the plan of an alternate form of acute crossing
Fig. 3 is the plan of an obtuse crossing
Fig. 4 is the plan of an alternate form of obtuse crossing
Fig. 5 is the plan of another form of obtuse crossing, and
Fig. 6 is the plan of a crossing in which the rails are halved together.
Referring to the crossing shown in Fig. 1, the rail a is bent at a', a³, a³, and is
grooved at a, while the rail 6 is bent at only and is grooved at 62. The drawing
also shows check rails c but these form no part of this or the other crossings shown.
They are used for additional safety as in the ordinary crossings.
In the crossing shown in Fig. 2 the rails d and e are both bent at d' and are
provided with grooves e as shown. Check rails c are also provided.
In Fig. 3 the rail is bent at f' and has grooves f" on each side of the bend.
The rail is beut at 91, 92, 9³ and placed close to the outside of the bend ƒ¹as
shown. A check rail c is also shown.
In the crossing shown in Fig. 4 the rail his bent at h¹, h, but is not grooved
while the rail is bent at similarly to the rail and in addition is grooved
at k³ and k. A check rail.c is also shown.
The crossing shown in Fig. 5 consists of rails which are bent similarly to the
rails used for the crossing shown in Fig. 3. The rail which is bent at and 1³
is also grooved at 1, and the rail m which is bent at m' is without grooves. The
check rail is marked c as in the other crossings.
In Fig. 6 the crossing is formed of two rails which are halved together. The
rail n has a flange groove n³, and also a space on its upper side for the reception of
the rail o which is correspondingly cut away on its under side and provided with a
flange groove o on its upper side.
The crossings horein described are made from rails of any of the usual sections,
and the metal displaced by the formation of the groove is pressed back into the
web of the rail, thus maintaining au uniform strength of the rail. The grooves
are preferably formed by bydraulic presses but they may be cut out. It the latter
case rails of special section are, used so as 'obtain the necessary strength at the cut
away part.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A railway crossing formed of two. rails one of which has three bends and one
groove while the other rail has one bend and one groove, and the arrangement of
such rails whereby each rail forms part of the through line and also part of the
crossing line substantially as herein described with reference to Big. 1 of the
accompanying drawings.
2. A railway crossing constructed of two rails both of which are similarly bent
and grooved, and arranged to form part of the through line and also part of the
crossing line substantially as herein described with reference to Fig. 2 of the
accompanying drawings.
3. A railway crossing constructed of two rails one of which has one bend and
two grooves while the other rail has three bends and no grooves, and the arrange-
ment of such rails whereby cach rail forms part of the crossing line and also part
of the through line substantially as herein described with reference to Fig. 3 of the
accompanying drawings.
4. A railway crossing constructed of two rails both of which are similarly bent,
one rail having two grooves while the other rail has no grooves and the arrangement

page_text: of such rails whereby each rail forms part of the through lifle and also part
of the crossing line substantially as herein described with reference to Fig. 4 of the
accompanying drawings.
5. A railway crossing constructed of two rails one of which has three bends and
two grooves while the other rail has one bend and no grooves, and the arrange-
ment of such rails whereby each rail forms part of the through line and also part
of the crossing line substantially as herein described with reference to Fig. 5 of the
accompanying drawings.
6. A railway crossing constructed of two rails halved together, suitably grooved
and arranged substantially as herein described with reference to Fig. 6 of the
accompanying drawings.
