Year: 1883

page_text: LETTERS PATENT to Samuel Leadbeater of Morley near Leeds in the
County of York for an Invention of “IMPROVEMENTS IN RAILWAY CHAIRS
AND IN THE MEANS OR APPARATUS FOR SECURING THE HAILS THERETO
"
PROVISIONAL SPECIFICATION left by the said Samuel Leadbeater at the
Office of the Commissioners of Patents on the 4th August 1883.
SAMUEL LEADBEATER of Morley near Leeds in the County, of York "IMPROVE-
MENTS IN RAILWAY CHAIRS AND IN THE MEANS OR APPARATUS FOR SECURING
THE RAILS THERETO
"
The object of my improvements is to provide a chair and apparatus in connection
therewith, whereby the rails are held firmly in position so as not to be loosened
by the passing of trains or other rolling bodies over their surfaces.
The rail may be of ordinary construction. The chair is formed on one side to
receive the rail and the other is bevelled off to receive a metallic key, the outer
end of such key is formed so as to fit against the other side of the rail.. The inner,
portion is provided with a web arranged to slide in a corresponding groove in the
bevelled side of the chair; or the bevelled side of the chair may be provided with
a web which passes into a corresponding groove in the key. These grooves and'
webs extend down the bevelled sides. After the rail has been placed in position
the key is passed down within the chair. In order to retain the rail tightly in
position in the chair I pass a horizontal wedge or cotter into a slot hole which is
provided partly in the bevelled side of the chair and partly in that of the key;
this being knocked in, forces the key tight against the rail holding it firmly. The
smaller end of the cotter or wedge is split into which is passed a locking wedge
preventing thereby the cotter or wedgo working loose.
When preferred a vertical cotter can be passed through a hole in the horizontal
cotter instead of a wedge.

SAMUEL LEADBEATER of Morley near Leeds in the County of York IMPROVE-
MENTS IN RAILWAY CHAIRS AND THE MEANS OR APPARATUS FOR SECURING THE
RAILS THERETO.
The object of my improvements is to provide a chair and apparatus in connection
therewith, whereby the rails are held firmly in position so as not to be loosened by
the passing of trains or other rolling bodies over their surfaces.
The rail may be of ordinary construction. The chair is formed on one side to
receive the rail and the other is bevelled off to receive a metallic key the outer end
of such key is formed so as to fit against the other side of the rail. The inner
portion is provided with a web arranged to slide in a corresponding groove in
the bevelled side of the chair, or the bevelled side of the chair may be provided
with a web which passes into a corresponding groove in the key. These grooves
and webs extend down the bevelled sides. After the rail has been placed in
--position, the key is passed down within the chair. In order to retain the rail
tightly in position in the chair I pass a horizontal-wedge-or-cotter_into_a_slot hole
which is provided partly in the bevelled side of the chair and partly in that of the
key; this being knocked in forces the key tight against the rail holding it firmly.
The smaller end of the cotter or wedge is split into which is passed a locking
wedge preventing thereby the cotter or wedge working loose
When preferred a vertical cotter can be passed through a hole in the horizontal
cotter instead of a wedge.
And in order thet
Invention
ma
mow he more
completely understood.
Fig 1 is a front elevation and Fig 2 a plan of a railway chair constructed in
accordance with my Improvemonts. Fig 3 is a front elevation and Fig 4 is a
plan showing my Improvements applied to a railway chair employed instead of
'fish plates and bolts.
a is the rail which may be of any ordinary construction and section. b is the
chair which is formed on one side to receive and fit the rail a. The opposite side
of the chair is bevelled or inclined to receive the metallic key c, one side of which
is formed to fit the side of the rail a and the opposite side to fit the incline of
the chair b. The inclined side of the key c is provided with a broad web arranged
to slide in a corresponding groove in tho bevelled side of the chair; or the bevelled
side of the chair may have the web, and the corresponding grooves formed in the
key. These grooves and webs extend down the bevelled sides of both chair b
and key c
After the rail a has been placed in position the key c is passed down within the
chair b. And in order to retain the rail a tightly and firmly in position in the
chair b a wedge or cotter d is passed into the slot hole provided for it partly in
the bevelled side of the chair band partly in the corresponding side of the key o,
this being knocked in forces the key c tight against the rail a. The slot hole for
the cotter d is shewn horizontal, but may be made inclined or vertical. In Figs 2
and 4 the wide end of the cotter d is shewn provided with a lip or projection i
This is for the purpose of readily knocking the wedge & into a horizontal position

page_text: in the slot hole after it has been inserted in the slot hole in an inclined position.
The slot hole is of such a section that the cotter d can readily be passed into it
in an inclined position but is firmly and tightly fixed when turned into a horizontal
position. The smaller end of the cotter d or wedgo is split and a locking wedgo
or cotter e is passed through the slit thereby preventing the cotter d from working
loose. In order to rotain the key c more firmly in position, the bolt or screw f
may be employed which is passed through the key c and the chair band when
preferred also through the sleeper.
When used as a substitute for 'fish plates' it will be seen from Figs 3 and 4
that the chair is made considerably wider and when preferred may be provided
with projections g which fit in what would otherwise have been the bolt holes for
the fish plate bolts. Where this arrangement of chair is employed and the mode
above described employed for securing the rails to the same, fish plates' may be
entirely dispensed with.
'
Having now described the nature of my said Invention and shewn by the
aid of drawings how the same may be carried into practico I would have it
understood that I do not limit myself to the precise details and configuration of
the parts I have described and shewn as the same may be varied or modified
without departing from the nature of my said Invention; what I do claim is -
The arrangement construction and application of the chair b, and also tho
key c and the wedge or cotter & for securing the rail a to the chair b substan-
tially as heroin set forth.
In Witness whereof I the said Samuol Leadbeater have hereunto set my
hand and seal this twenty third day of January in the year of our Lord
one thousand eight hundred and eighty four.
