page_text: We JOHN TAYLOR and HENRY TAYLOR of No. 98 Portland Road Nottingham
Tobacconists and Cigarette Manufacturers but retired from business, 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 the invention is to effect the secure holding in position of railway
rails by means of improved chairs to the sleepers without the necessity for wooden
keys or packing pieces.
In general the rails of railways in Great Britain are laid within the jaws of chairs
on sleepers and are retained fixed therein by means of wedges or keys of wood more
or less compressed, said keys being driven in between rail and fixed chair jaws to
obtain a grip, also the rails are in parts or lengths and separate lengths are "fished"
together by "fish" plates laid one on each side of the butted ends of the rails and
then bolts and nuts grip the three layers together.
The invention relates also to means for dispensing with the use of such fish plates,
by gripping the two butted ends of rails in a chair according to our invention.
The invention is carried into practice by forming the chair into two separable
gripping parts or jaws one of which slides on and is guided and adjusted relatively to
the other so as to be separated to allow of the rail being put in place and then the
jaws are drawn together, gripping the rail or part rails tightly and these parts are
retained in place relatively by means of bolts and nuts passed through the sliding and
fixed jaws below the rails thereby avoiding the labour of boring, and danger of
weakening the rails.
In so fixing rails at points or crossings, the rails in some cases are held in a com-
pound chair consisting of an outer fixed jaw against which one side of one rail abuts
then a sliding filling piece shaped to the contour of the adjacent rails then the second
rail and then the loose sliding guided jaw, the whole being clamped or drawn together
by means of screw bolts passing through the part chairs and dividing piece below the
rails and tightened up by nuts.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a rail in cross section resting in a railway chair shown in end
view.
Fig. 2 is a plan view of same.
Fig. 3 is a side view looking across the line of rails.
Fig. 4 is an end view of the sliding jaw, and Fig. 5 a like view of the fixed jaw of
the chair shown by Fig. 1.
Figs. 6 and 7 show respectively, separately, the sliding and fixed jaws in plan.
Figs. 8 and 9 show respectively the inner or gripping faces of the sliding and fixed
jaws.
Fig. 10 shows by a like view to Fig 1 another arrangement, or modification of
chair adapted to connect together two abutting rails as well as to grip and support
the line of rail.
Fig. 11 shows by plan view and
Fig. 12 by side view corresponding, the arrangement of the parts.
show in detail separate views of parts.

Fig. 1 in order to adapt it to holding two rails with the interposition of a distance
piece, the chair bed on which the sliding jaw moves being extended accordingly.

rail against which it presses and its base is extended to give a firm bearing on
the fixed part of the chair. This loose jaw has shoulders 62, 6 bored to receive the

sliding jaw separately by view corresponding to
In the arrangement, Fig. 10, the jaws band d are extended forward and backward
so as to embrace the meeting ends of two abutting rails and thereby enable fish
plates to be dispensed with at such parts.
The arrangement indicated by Fig. 19 differs from Fig. 1 in that there is an
extended base to the bottom of the chair and a corresponding extension of the part d²
of the fixed jaw d also two rails are interposed between the sliding and fixed jaws b, d
these two rails again being separated by the distance piece e which has a base
portion e formed with dovetailed grooves e corresponding to the projecting ribs d', d
on which this part e is slidden, followed by the loose jaw b, and corresponding bolt-
holes et admit the bolts e which passsing through these holes in parts b, e, d, lock all
together onto the rails a when the nuts e² are screwed up by the aid of a spanner.
The form of the parts on which the sliding jaws slide in their traverse to and from
the rails on the fixed jaw portions of the chairs, and the relative projections and
recesses may be reversed in position.
The number of rails held in each chair may be varied as also will, in such case, be
the number of distance pieces and the extent of base given to the under chair.
We would have it understood that we are aware that it has been proposed to
construct railway chairs in halves or parts held to the rails, and to each other by bolts
passing therethrough but such arrangements have not been satisfactory or generally
adopted and we make no claim broadly to chairs formed in parts bolted together and
to the rails, but, having now particularly described and ascertained the nature of
our said Invention, and in what manner the same is to be performed, we declare
that what we claim is:
The combination or arrangements and use of parts of chairs for holding rails
consisting of a loose or sliding jaw part, a fixed jaw part adapted to support and
guide the loose jaw part and means of drawing and holding tightly together said
part on a rail or rails, with or without the interposition of a distance piece or pieces,
all substantially as and for the purposes set forth.
