Improvements in Rails, Sleepers, and Chairs for Colliery and other
Tramways.
I, JAMES FORD of 48 Sackville Street Barnsley in the County of York
Mining Engineer and Lecturer 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 has reference to colliery and similar tramways its object being to
so arrange the same that they may be easily and expeditiously constructed and at
the same time form a rigid and substantial road to attain which I construct my
improved tramway in the manner set forth in the accompanying sheet of drawings
of which the following is a description.
Fig. 1 is a cross sectional elevation and Fig. 2 a longitudinal elevation of one
arrangement of my present improvements and Fig. 3 is a cross sectional elevation
of a modification thereof.
Fig. 4 is a longitudinal elevation Fig. 5 a cross sectional elevation on line a a
and Fig. 6 a cross sectional elevation on line bb of said Fig. 4 of a further modifi-
cation of my invention.
Similar letters of reference denote corresponding parts in each view.
Referring to Figs. 1 and 2 I arrange chairs C and cast press or forge the same
out of suitable metal and in one with the sleeper S. Each chair C is formed with
a concave or curved portion c¹ in order to receive the convex or rounded under

formed in it for the reception of the cotters or keys D which also bear in grooves c²
formed in the chairs C so that the rails R are held in position and prevented
lifting. The said chairs C are formed with horizontal holes for the purpose of
enabling the end of a lever chisel or other instrument being forced therein in
order to remove the cotters or keys D as will be well understood. Referring to
Fig. 3 the chair C is formed without the horizontal groove and separate from the
sleeper S to which latter the said chair may be bolted or otherwise secured in any

formed with a projecting portion which rests in a tapered recess c formed in the
centre part of each chair C and in order to lift the ends of the rails R from the
chair the end of a lever or similar instrument is passed through the hole c formed
in side of each chair as shown. The chairs C shown at Figs. 4 5 and 6 are
illustrated as being made in one with the sleepers S but it will be obvious that the
said chairs may be made separate where preferred and likewise the special form of
chairs shown at Figs. 1 and 2 may be made separate from the sleepers S.
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. In colliery or similar tramways the use of a rail of a cross sectional form such
as R in combination with a chair C formed in one with or separate from the
sleeper S and arranged with a groove c' and secured to said chair by means of keys
or cotters D all arranged substantially as described and shown at Figs. 1 and 2 of
the drawings annexed.
2. In colliery and similar tramways the use of a rail of a cross sectional form
such as R in combination with a chair C substantially as described and illustrated
at Fig. of the accompanying sheet of drawings.
3. In colliery or similar tramways the use of a rail R of form in cross section as
shown at Fig. 5 and having projecting or deep ends as shown at Figs. 4 and 6 in

page_text: combination with a chair C formed with a recess part of for the reception of said
ends substantially as described and illustrated at Figs. 4, 5 and 6 of the drawings
attached hereto.
