ALEXANDER TERTIUS HARVEY 23 Grange Road West Middlesbrough Draughtsman,
do hereby declare the nature of this Invention to be as follows, that is to say :-
My said Invention has for its object to provide improved chairs and fastenings for
Vignoles and other forms of rails which are made with and fixed by means of bottom
flanges. My improved chair and fastening forms a combination device which is
advantageously suitable for the rails at crossings and switches as well as at other
parts.
In carrying out my Invention I use as a fastening a key of a kind already in use
with certain kinds of sleeper-chairs; and by forming a chair principally of cast iron
so that certain parts of it act in combination with such a key 1 not only form a good
combination fastening device in itself, but also am able to use the same kind of key
for chairs at crossings and switches as those which may be used with sleeper chairs at
other parts of a line. My improved chair is cast with or without a clipping projection
to retain one edge of the bottom flange of the rail, and the other edge or both are
retained by the key which is shaped to bear against the edge and upon the top of the
flange close to the edge. The key is of the usual long tapered shape and is driven
along the rail in between the edge of its bottom flange and a steel clipping piece,
which is curved or otherwise shaped to fit the back of the key. This steel clipping
piece is fixed by the chair being cast on it; and its bearing surface or that of the
back of the key or both may be corrugated or serrated to prevent the slipping of
the key.
The Invention is applicable to various kinds of cast-iron railway chairs including
cast-iron sleeper chairs.

page_text: I, ALEXANDER TERTIUS HARVEY, of 23 Grange Road West, Middlesbrough, in the
County of York, Draughtsman, 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, that is to say :-
My said Invention has for its object to provide improved chairs and fastenings for
Vignoles and other forms of rails which are made with and fixed by means of bottom
flanges. My improved chair and fastening forms a combination device which is
advantageously suitable for tho rails, at crossings and switches as well as at other
parts.
In carrying out my Invention I use as a fastening a key of a kind already in use
with certain kinds of sleeper-chairs; and by forming a chair principally of cast iron so
that certain parts of it act in combination with such a key I not only form
a good combination fastening device in itself, but also am able to use the same kind of
key for chairs at crossings and switches as those which may be used with sleeper
chairs at other parts of the line. My improved chair is cast with or without a clipping
projection to retain one edge of the bottom flange of the rail, and the other edge is
retained by the key which is shaped to bear against the edge and upon the top of the
flange close to the edge. The key is of the usual long tapered shape and is driven
along the rail in between the edge of its bottom flange and a steel clipping piece,
which is 'curved or otherwise shaped to fit the back of the key. This steel clipping
piece is fixed by the chair being cast on it; and its bearing surface or that of the back
of the key or both may be corrugated or serrated to prevent the slipping of the key.
may sometimes be convenient or desirable to apply keys at both sides of a rail.
My Invention is applicable to various kinds of cast iron railway chairs including
cast iron sleeper chairs; and I show examples of such applications on two accom-
panying sheets of explanatory drawings.
It
In Figures, 1, and 2, on sheet, 1, of the drawings there is shown in sectional
elevation and in plan, a cast iron chair for holding two rails which are near together
at a crossing. The chair is shown in section in figure, 3. Figures, 4, and 5, are a
sectional elevation and a plan of a cast iron chair for a single rail; and figures, 6,
and 7, on sheet, 2, are similar views of a cast-iron-sleeper-chair.
The chair shown in figures, 1, 2, and 3, has steel clip pieces, C, fixed in it by the
casting of the chair with these pieces placed in position in the mould. The two
rails, R, R, are bolted together with a distance piece, D, between them so as to form
virtually a singlo broad piece which is fixed to the chair by means of the taper
keys, K. Each key, K, is made with a groove along its inner part such groove being
shaped so that the key bears against the outer edge of the bottom flange of the rail
and also on the top of that flange close to the edge. Chairs of the kind shown in
figures, 1, 2, and 3, can of course be made to suit different distances and inclinations
between the rails.

page_text: In a chair for a single rail shown in figures, 4, and 5, a clip-like projection, P, is
cast on the chair to retain one edge of the bottom flange of the rail, the other edge
being secured by means of a taper key, K, wedged in between it and a cast-in steel
clip, C.
In the case of the sleeper chair shown in figures, 6, and 7, two clip-like pro-
jections, P, are cast on the chair for retaining one edge of the bottom flange of the
rail, a cast-in steel clip, C, and taper key, K, being provided for the other edge.
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 :-
--
The improved railway chairs and fastenings in which are combined in each case
a cast iron chair, one or more cast-in steel clips, and one or more tapered keys shaped
to bear against the edge and upon the top of the bottom flange of a Vignoles or other
bottom-flanged rail, substantially as hereinbefore described.
