Maker, both of 312 Ashton Old Road, Openshaw near Manchester in the County
of Lancaster do hereby declare the nature of our invention of "IMPROVEMENTS
to be as
IN CHAIRS AND SLEEPERS FOR NARROW GUAGE AND OTHER RAILWAYS
follows

"
-
The object of this invention is to dispense with the rivets or bolts and nuts as
hitherto employed for securing the rail to the metal sleeper especially in narrow
guage railways and thus to obviate the tendency to shake loose by vibration
In performing our invention we construct the chair, as seen in sectional view on
the accompanying drawing, in two portions a and b by preference of plate steel-
one a lying upon the other band having its central part cut away to permit the
corresponding central part o of the other to pass through In this manner and by
bending back the outer extremity d of the upper central part, facility is afforded
for grasping the base of the rail e on both sides
The outer parts of the chair on both sides are bent downwards and pass through
holes and g formed in the metal sleeper h at each side of the rail and the outer
extremity of the upper one being bent backwards as aforesaid, facility is thus
afforded for grasping the under side of the sleeper h by both parts of the chair.
And in order to secure the two parts of the chair together and at the same time to
clamp the rail e to the sleeper h the inner extremities a¹ and 6' of the two parts of
the chair are bent upwards at right angles and at a suitable distance from each
other and thus are capable of being drawn close together by a bolt and nut k and
which bolt and nut in this position is always accessible for tightening purposes
without disturbing the sleeper.

page_text: We JOHN FOULDS WRIGHT, Manager and WILLIAM HERRIS WRIGHT, Pattern
Maker both of 312 Ashton Old Road, Openshaw near Manchester in the County
of Lancaster do hereby declare the nature of our invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement
-
The object of this invention is to dispense with the rivets or bolts and nuts as
hitherto employed for securing the rail to the metal sleeper especially in narrow
guage railways and thus to obviate the tendency to shake loose by vibration
On the accompanying drawing Fig 1 is a plan view, Fig 2 a longitudinal
section and Fig 3 an end elevation of a piece of rail secured to a metal sleeper by 1
an improved chair in accordance with our improvements.
In performing our invention we construct the chair in two portions A and B as
seen in Figs 4 and 5, and 6 and 7 which represent plan and side view respectively
of each portion separately-by preference of plate steel-one (A) lying upon the
other (B) as seen more clearly in Fig 2 and having its central part a cut away to 1
permit the corresponding central part 6 of the other to pass through
In this manner and by bending back the outer extremity c of the upper central
part facility is afforded for grasping the base of the rail d on both sides
The outer parts e of the chair on both sides are bent downwards and pass
through holes f formed in the metal sleeper g at each side of the rail d and the 2
outer extremities e of the upper one being bent backwards as illustrated facility
18 thus afforded for grasping the under side of the said sleeper by both parts of
the chair
And in order to secure the two parts (A and B) of the chair together and at the
same time to clamp the rail to the sleeper g the inner extremities of the two 2
parts of the chair are bent upwards at right angles and at a suitable distance
from each other and thus are capable of being drawn closer together by a bolt and
nut and which bolt and nut in this position is always accessible for tightening
purposes without disturbing the sleeper
It will thus be apparent that in accordance with our improvements the chair and
rail are both secured or clamped simultaneously to the metal aleeper by a single
bolt and nut and thus the risk of shaking loose by vibration is reduced to the
minimum.

page_text: Having thus particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed we declare that what
we claim is
The constructing of chairs, especially for narrow guage railways, in two portions
and securing the same and the rail to the metal sleeper, substantially as and
for the purposes hereinbefore described and illustrated on the accompanying
drawing.
