Improvements in Railway Chairs and Fastenings for the Permanent
Way of Railways.
I RICHARD AMES of No. 2 Clifton Crescent Colliery Road Nottingham,
Foreman Pattern Maker do hereby declare the nature of this invention to be as
follows: :-
The object of my invention is an improvement in the construction of railway
chairs & fastenings for the permanent way of railways by making or constructing
the said chairs & fastenings so that a cheap & strong cast iron fastening may be
used for securing flat bottom & other rails to the chairs the said fastening to be
secured to the chair by means of a bolt & lock nut in place of the wrought iron
wedge generally used, the said bolt to be placed so that the nut is in the most
convenient position for screwing up or unscrewing & is also out of the way of any
bolts or nuts which may be attached to the web of the rail, the said chair &
fastening to-be'also made or constructed so that when the fastening is placed in its
position in the chair it shall not be able to get out of its place in the event of the
nut getting loose or the bolt breaking, thus preventing the rail from moving more
than the small amount of clearance required to get the fastening into its place.
To do this I make the chair of sufficient thickness to allow for a slot or groove
to be made in the bed or bearing surface of the chair at a right angle with the
length of the rail & parallel with the bed or bearing surface of the chair to receive
a bolt the said bolt to have the head tapered on two sides & flattened on the other
two sides to the diameter of the bolt, the slot or groove is made sufficiently deep
to take the bolt head in its widest part so as to allow of the bolt being put in or
taken out when the rail is in its place on the chair. Where required one bolt may
be used for two fastenings by making a straight slot or groove through the bed
or bearing surface of the chair. A sinking or recess is formed at the edge of the
bed or bearing surface of the chair to receive the fastening, a taper bed or face
being constructed at an angle with & projecting under the bed or bearing surface
of the chair. Stops or lugs are formed at each end of the recess & returned at
the back, sufficient space being left between the return stops or lugs to allow the
boss on the fastening to pass between. Other parts of the chair are reduced in
thickness & left sufficiently strong to answer their purpose. The fastening is made
or constructed to clip the flange of the rail & has a taper projection or face formed
to suit the taper bed or face in the chair, so that when the fastening is forced by
the bolt & nut up to the said taper bed or face it shall cause the said fastening
to pull in a downward direction thus causing it to grip the flange of the rail &
hold it securely to the bed or bearing surface of the chair, a boss is formed on the
centre of the fastening with a slot or groove through it for the bolt to pass through,
the parts of the fastening from each side of the boss to the end, are set back from
the face of the boss & curved so as to give as near as possible a parallel thickness
with the taper projection or face, this allows additional strength to be given to the
return stops or lugs by curving them to suit, & also enables the fastening to be put
into its place in the chair with a very small amount of clearance between the said
fastening & the stops or lugs by working the said fastening into the chair in a
circular direction to suit the said curved parts. Thus by fixing the bolt in the
chair parallel with the bed or bearing surface of the said chair I get the nut in
the most convenient position for screwing up or unscrewing, & by forming the stops
or lugs on the chair & shaping the fastening so as to get it into its place in the chair

Improvements in Railway Chairs and Fastenings for the Permanent
Way of Railways.
I, RICHARD AMES, of No. 2 Clifton Crescent, Colliery Road, Nottingham,
Foreman Pattern Maker, 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 :-
:
The object of my invention is an improvement in the construction of railway
chairs & fastenings for the permanent ways of railways by making or constructing
the said chairs & fastenings so that a strong & cheap cast iron fastening may be
used for securing flat bottom & other rails to the chairs. The said fastening to be
secured to the chair by means of a bolt & lock nut in place of the wrought iron
wedge generally used, the said bolt to be placed so that the nut is in the most
convenient position for screwing up & unscrewing & is also out of the way of any.
bolts or nuts that may be attached to the web of the rail, the said. chair &
fastening to be also made or constructed so that when the fastening is placed in
its position in the chair it shall not be able to get out of its place in the event
of the nut getting loose or the bolt breaking thus preventing the rail from
moving more than the small amount of clearance required to get the fastening
into its place.
To do this I make the chair of sufficient thickness to allow for a slot or groove
to be made in the bed or bearing surface of the chair at a right angle with the
length of the rail & parallel with the bed or bearing surface of the chair to receive
a bolt the said bolt to have the head tapered on two sides & flattened on the other
two sides to the diameter of the bolt, the slot or groove is made sufficiently deep to
take the bolt head in its widest part so as to allow of the bolt being put in or taken
out when the rail is in its place on the chair, the slot or groove may also be
continued through the chair so that one bolt may be used to secure two fastenings,
a sinking or recess is formed at the edge of the bed or bearing surface of the chair
to receive the fastening, a taper bed or face being constructed at an angle with &
projecting under the bed or bearing surface of the chair, stops or lugs are formed
at each end of the recess & returned at the back, sufficient space being left between
the return stops to allow the boss on the fastening to pass between, other parts of
the chair are reduced in thickness & left sufficiently strong to answer their purpose.
The fastening is made or constructed to clip the flange of the rail & has a taper
projection or face formed to suit the taper bed or face in the chair so that when the
fastening is forced by the bolt & nut up to the said taper bed or face it shall cause
the said fastening to pull in a downward direction, thus causing it to grip the
flange of the rail & hold it securely to the bed of the chair a boss is formed on the
centre of the fastening with a slot or groove through it for the bolt to pass through,
the parts of the fastening from each side of the boss to the end, are set back from
the face of the boss & curved so as to give as near as possible a parallel thickness
with the taper projection or face, this allows additional strength to be given to the
return stops or lugs by curving them to suit & also enables the fastening to be put
into its place in the chair with a very small amount of clearance between the said
fastening & the stops or lugs, by working the said fastening into the chair in a
circular direction to suit the said curved parts thus by fixing the bolt in the chair
parallel with the bed or bearing surface of the said chair I get the nut in the most
convenient position for screwing up, or unscrewing & by forming the stops or lugs
on the chair & by shaping the fastening so as to get it into its place in the chair

page_text: with a very small amount of clearance between the said fastening & the stops or
lugs, I am able to prevent the rail moving more than the said small amount of
clearance in the event of the fastening getting loose.
My invention will be more fully understood & carried into effect by reference to
the drawings hereto appended whereon my improved chair & fastening is represented
as follows:-
Figure 1. half elevation & half section of chair designed to take a seperate bolt
for each fastening.
Figure 2. plan of same chair.
Figure 3. plan of chair with slot or groove continued through & designed for one
ordinary bolt to secure two fastenings.
Figures 4 & 5. end elevations of chair.
Figure 6. side elevation of fastening.
Figure 7. end elevation of fastening.
The various parts are indicated by letters of reference as follows-
A is the chair, B is the slot or groove for the bolt, C is a bolt with the head
shaped to suit the recess made in the chair to receive it, D is the part of the chair
shaped to receive the fastening, E is a taper or inclined bed or face, F are stops or
lugs to prevent the fastening getting out of place.
G is the fastening or clamp with a taper or inclined face H, shaped to suit the
angle of the inclined face E in the chair, I is a rib recessed to receive the flange
of the rail, distance blocks may be substituted & bolted between the webs of the
rails in place of the rib I.
Lis a stud or support for the bolt. M are projections formed to support the
bolt head in position.
The effective application of the various parts are as hereinbefore described, that
is when the nut N is screwed up to the fastening G it causes the taper or inclined
face H to slide in a downward direction on the taper or inclined face E in the
chair, thus causing the fastening G to grip the flange or bottom of the rail K &
hold it securely to the bed of the chair A.
My improved chair may be made to suit different inclinations & distances
between the rails & may also be applied to various kinds of railway chairs.
Having now particularly described & ascertained the nature of my said inven-
vention & in what manner the same is to be performed, I declare that what I
claim is-
1st. Forming or constructing railway chairs with one or more slots or grooves B
in the bed or bearing surface of the chair A in combination with one or more
fastenings or clamps, G, shaped as herein before described & bolted to the chair for
the purposes herein explained, & shown on the drawings.
2nd. An improved railway chair & fastening combining a cast iron chair A.
formed or constructed with lugs or stops F. shaped to suit the fastening G. one or
more fastenings or clamps G shaped to suit the chair A & lugs or stops F, so that
the fastening or clamp G may be put into its place with a small amount of
clearance & be prevented from getting out of its place by the lugs or stops F.
One or more bolts with, self-locking or ordinary nuts for securing the fastenings or
clamps G to the chair A all for the purposes herein described & set forth & shown
in the drawings herewith appended.
