Improved Method of Jointing the Rails of Railways.
JOHN STANLEY HOLME of 28 The Park, Eccles, County of Lancaster and
FRANK BROOKS HART, 49 Old Road Heaton Chapel Manchester Civil Engineer
do hereby declare the nature of this invention to be as follows :-
:-
This device in railway or other joints of rails is applicable to solid double headed
rails.
:
It has for its object, firstly to eliminate the jolting and shocks experienced by
passengers in consequence of the wheels of railway carriages passing over the joints
of rails.
Secondly, to prevent excessive vibration and damage to rolling stock caused by
the present square joint.
Thirdly, to dispense with fish plates now used as an equivalent for continuity of
rail.
Fourthly, to prevent distortion and the rails being thrown out of linc, consequent
upon abnormal expansion of the metals, caused by hot weather.
These advantages are effected by "splicing" the ends of the rails in such form
that the joint shall be as strong as the ordinary rail.
One end of the rail is tapered, by cutting or pressing, on one side; the other end
of the same rail is shaped in a like manner on the opposite side of the rail.
The cut of the rail is made diagonally and vertically.
The taper commences (plan of upper head of rail) at the thick end or full rail
with a short curve (or short straight) cutting inwards to the centre of rail. The
other end of the said short curve is tangential to, and joins, a straight line or taper
proper which cuts the rail diagonally at an acute augle. The end of the said
straight line or taper proper joins again to a short curve striking outwards from
the centre of the rail in an opposite direction to the short curve first before
named.
The bottom flange of the rail is treated and cut in a similar manner to the upper
head described.
The web of the rail is carried forward, the full thickness, several inches beyond
the end of the curve, at the thin end of the taper, and on the same side that the
rail is straight.
This continued web is closely housed against the web of the other rail between
the top and bottom flanges or heads.
The web of the rail is formed and shaped diagonally for part length of the taper
of the head to allow the web of the other rail to cross and splice.
Thus the webs of the two rails at the splice cross and double lock.
Bolts secure the web at the thin end of the taper of one rail, to the web at the
thick end of the taper of the other rail.
Elongated bolt holes are made in the webs to admit of necessary contraction and
expansion.
The joint may be made between chairs or may be supported by a joint chair or
ordinary chair.
In the latter case the webs at the taper of the joint will be reduced in thickness,
or the full thickness of the web may be retained and a special chair with wide
jaws used.

and FRANK BROOKS HART 49 Old Road Heaton Chapel Manchester Civil
Engineer 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 devise in railway or other joiuts of rails is applicable to solid double headed
rails.
It has for its object firstly: to eliminate the jolting and shocks experienced by
passengers in consequence of the wheels of railway carriages passing over the joints
of rails.
Secondly to prevent excessive vibration and damage to rolling stock caused by
the present square joint.
Thirdly to dispense with fish plates now used as an equivalent for continuity of
rail.
Fourthly to prevent distortion and the rails being thrown out of line consequent
upon abnormal expansion of the metals caused by hot weather.
These advantages are effected by "splicing
the ends of the rails in such form
that the joint shall be as strong as the ordinary rail.
One end of the rail is tapered by cutting or pressing on one side; the other end
of the same rail is shaped in a like manner on the opposite side of the rail.
The cut of the rail is made diagonally and vertically.
The taper commences (plan of upper head of rail) at the thick end or full rail
with a short curve (or short straight) cutting inwards to the centre of rail.
The other end of the said short curve is tangential to, and joins, a straight line
or taper proper which cuts the rail diagonally at an acute angle. The end of the
said straight line or taper proper joins again to a short curve striking outwards
from the centre of the rail in an opposite direction to the short curve first before
named.
The bottom flange of the rail is treated and cut in a similar manner to the upper
head described.
The web of the rail is carried forward, the full thickness, several inches beyond
the end of the curve at the thin end of the taper and on the same side that the rail
is straight.
This continued web is closely housed against the web of the other rail between
the top and bottom flanges or heads.
The web of the rail is formed and shaped diagonally for part length of the
taper of the head to allow the web of the other rail to cross and splice.
Thus the webs of the two rails cross and double lock.
Bolts secure the web, at the thin end of the taper of one rail to the web at the
thick end of the taper of the other rail.
Elongated bolt holes are made in the webs to admit of necessary contraction and
expansion.
The joint may be made between chairs or may be supported by a joint chair or
ordinary chair.
In the latter case the webs at the taper of the joint will be reduced in
thickness, or the full thickness of the web may be retained and a special chair
with wide jaws used.
Referring to the drawings
Figs. 1 and 1 are plans of rail ends shewing tapers 6 with curves at each
end of taper as described.

page_text: Fig. 6 section at 7 (Figs. 3 & 4).
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. The use of S curve taper for forming splice or joint of rails.
2. The bending and crossing of the webs of rails at joint as described.
3. The extended web bearing on bottom flange at joint.
4. The double lock or splice of rails at joint formed by the triple combination
viz. taper joint, crossing of webs and extended webs.
