Improvements in or connected with Rail Chairs.
1 JOSEPH PETITJEAN, of 27 Rue Nysten, Liège in the Kingdom of Belgium,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a novel method of fastening "Vignole" rails to metallic
or wooden sleepers composed of a special chair and a novel keying arrangement to
fix the rail in the chair.
On the accompanying sheet of drawing:
:-
Figure 1 is a transverse section through the middle of the chair set upon a metal
sleeper with rail and fastenings.
Figure 2 is a plan view of Figure 1.
Figure 3 is a side view of Figure 1.
Figure 4 is a section through the middle of a modification of the chair shown in
the preceding figures.
Figure 5 is the sleeper for the chair represented Figure 4.
Figure 6 is a plan view and
Figure 7 a transverse section at any point of the metallic filling piece.
The chair is composed of a seat a having the desired inclination, and of two
hooked ends or catches c, and c¹ of different size. These catches are curved towards
each other so that the catch c¹ which is on the inside of the way, clasps the foot d
of the rail, while the second and longer catch c, leaves between it and the rail, the
space required for the insertion of the filling piece of uniform transverse section,
and of a wooden tightening wedge or key o.
The seat a presents, between the catches c and c', sufficient space for placing
therein the foot d d' of the rail and a metallic filling piece of uniform transverse

the chair so that one of the sides d of the foot of the rail is introduced under the
catch c', there is placed parallel to the rail, between the part d' of the foot and the
base of the catch e the metallic filling piece which rests on the seat a of the chair.
On one lateral side, this piece i is of a section following that of the side of the
foot d of the rail used, which it partially covers and, on the three other sides, it is
rectilinear in the entire length of the chair; its ends, projecting on each side of the
chair are curved, immediately as they leave this latter, in the opposite horizontal
direction to that of the rail, Figures 2, 3 and 6. In the vacant space between the
placed a wooden
catch c, the rail and its foot d', and the metallic filling piece i,
wedge or key o intended to tighten the foot d' and the piece against the seat a of
the chair.
The chair represented Figures 1, 2 and 3 is provided on its lower face with
pierced sockets n, which serve for the passage of the rivets, bolts or wood-screws m
intended to secure the chair on the sleeper; these sockets are lodged in a longi-
tudinal groove p of the sleeper or in the body of the wooden sleeper. These
sockets n have for object, amongst others, to give greater stability to the chair.
The chair shown Figure 4 may also be made without the sockets n and be
entirely plane on its lower face; in this case, the section of the sleeper, Figure 5
will be preferably such as to present, on both sides of its upper part, flanges r
intended to support the chair.

page_text: The above described chair, with or without sockets may be used on wooden
sleepers and is then fixed in the ordinary manner by wood-screws.

I, JOSEPH PETITJEAN, of 27 Rue Nysten, Liege, in the Kingdom of Belgium,
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 relates to a novel method of fastening "Vignole" rails to metallic
or wooden sleepers composed of a special chair and a novel keying arrangement to
fix the rail in the chair.
On the sheet of drawing left with the Provisional Specification:
Figure 1 is a transverse section through the middle of the chair set upon a metal
sleeper with rail and fastenings.
Fig. 2 is a plan view of Fig. 1.
Figure 3 is a side view of Fig. 1.
Figure 4 is a section through the middle of a modification of the chair shown in
the preceding figures.
Figure 5 is the sleeper for the chair represented Fig. 4.
Figure 6 is a plan view, and
Fig. 7, a transverse section at any point of the metallic filling piece.
The chair is composed of a seat a having the desired inclination, and of two
hooked ends or catches c and e¹ of different size. These catches are curved towards
each other so that the catch c¹ which is on the inside of the way clasps the foot d
of the rail, while the second and longer catch leaves between it and the rail, the
space required for the insertion of the filling piece of uniform transverse section,
and of a wooden tightening wedge or key o.
The seat a presents, between the catches c and c¹ sufficient space for placing
therein the foot d, d' of the rail and a metallic filling piece i of uniform transverse
section throughout its entire length see Figures 6 and 7. The rail being placed
in the chair so that one of the sides d of the foot of the rail is introduced under the
catch e, there is placed parallel to the rail, between the parts of the foot and
the base of the catch e the metallic filling piece i which rests on the seat a of the
chair. On one lateral side, this piece is of a section following that of the side of the
foot d¹ of the rail used, which it partially covers and on the three other sides, it is
rectilinear in the entire length of the chair, its ends, projecting on each side of the
chair are curved, immediately as they leave this latter, in the opposite horizontal
direction to that of the rail, Figures 2, 3 and 6. In the vacant space between the
catch c, the rail and its foot d', and the metallic filling piece is placed a wooden
wedge or key o intended to tighten the foot d' and the piece i against the seat a of
the chair.
The chair represented Figures 1, 2 and 3 is provided on its lower face with
pierced sockets n which serve for the passage of the rivets, bolts, or wood screws m
intended to secure the chair on the sleeper these sockets are lodged in a
longitudinal groove p of the sleeper or in the body of the wooden sleeper. These
sockets have for object amongst others, to give greater stability to the chair.
l
The chair shown Fig. 4 may also be made without the sockets a and be entirely
plane on its lower face; in this case the section of the sleeper, Fig. 5 will be

page_text: preferably such as to present on both sides of its upper part, flanges, intended to
support the chair.
The above described chair, with or without sockets may be used on wooden
sleepers and is theu fixed in the ordinary manner by wood screws.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1) A chair for railway rails, consisting of a seat (a) and two catches directed the
one towards the other, one of which (c) clasps the foot of the rail, while the
other (c) longer and higher is intended to bold the filling piece (i) and wedge (o),
in combination with pierced sockets (n) in projection under the sole of the chair.
(2) For fixing the rail in the chair set forth in the preceding claim and with or
without sockets (): the use of a metallic filling piece (i) of uniform section in the
entire length of the chair one of its lateral faces being of a section following that
of the foot of the rail, which it partially covers, and the ends of which projecting
on the chair, are curved horizontally outward, and of a wooden tightening wedge (o)
driven into the free space between the catch (c) the metallic piece (i) the foot (d')
and the rail.
