PROVISIONAL SPECIFICATION.
Improvements in Rail Joints.
I, BENJAMIN BLEARS, of 137 Bag Lane, Atherton, in the County of Lancaster,
Mechanic, do hereby declare the nature of this invention to be as follows :-
This invention has reference to a construction of rail joint in which the adjacent
ends of rails are connected by two short supplementary lengths of rail so formed
and arranged in relation to each other as to form a tongue and groove joint, or
it may be a rabbet joint, and each formed with longitudinal extensions or jaws
by which it can be secured to the web of the corresponding rail by suitable
fastening devices such as bolts and nuts. The jointed portions of the two
supplementary lengths of rails are formed with corresponding slots through which
passes a pin or bolt by which the two portions are held together but nevertheless
in such a manner as to readily permit of expansion and contraction of the con-
nected rails. The joint thus formed is or may be supported by a chair formed
with lugs or extensions between which the jointed portions of the two supplementary
lengths of rail are placed and through which extends the bolt or pin hereinbefore
referred to.

COMPLETE SPECIFICATION.
Improvements in Rail Joints.
I, BENJAMIN BLEARS, of 137 Bag Lane, Atherton, in the County of Lancaster,
Mechanic, 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 a construction of rail joint in which the adjacent
ends of rails are connected by two short supplementary lengths of rail so formed
and arranged in relation to each other as to form a tongue and groove joint, or it
may be a rabbet joint, and each formed with longitudinal extensions or jaws by
which it can be secured to the web of the corresponding rail by suitable fastening
devices such as bolts and nuts. The jointed portions of the two supplementary
lengths of rails are formed with corresponding slots through which passes a pin or
bolt by which the two portions are held together but nevertheless in such a manner
as to readily permit of expansion and contraction of the connected rail. The joint
thus formed is or may be supported by a chair formed with lugs or extensions
between which the jointed portions of the two supplementary lengths of rail are
placed and through which extends the bolt or pin hereinbefore referred to.
In the accompanying drawings,
Fig. 1 is a plan; and
Fig. 2 a sectional elevation on the line x x Fig. 1, illustrating a rail joint
constructed according to this invention.
a and b are the end portions of the two lengths of rail to be connected together.
c is a short supplementary length of rail provided with longitudinal extensions or
jaws c¹ by which it is secured to the web of the rail a by bolts d. e is another
supplementary length of rail provided with a pair of longitudinal extensions or
jaws e¹ by which it is secured to the rail 6 by means of bolts d'. The rail c is
formed with a tongue c³ arranged to enter a correspondingly shaped groove e³ in
Paine dl

page_text: the rail e so as to form therewith a tongue and groove joint. f is a screw bolt
with nuts arranged to extend through slots g formed in the jointed parts of the
rails ce and serving to connect these rails together, the said slots being made
sufficiently long in relation to the diameter of the said bolt to allow for expansion
and contraction of the rails a b. For the same reason spaces are left between
adjacent parts of the rail c and e as shown at h. i is a chair formed with lugs k
between which the jointed portions of the rail ce are placed and through which in
the example shown the bolt f passes. This chair serves to support the rail joint
both vertically and laterally.
Fig. 3 is a plan illustrating a modified arrangement in which the overlapping
portions e²e of the supplementary lengths of rail ce form a rabbet joint instead of
a tongue and groove joint. In other respects the arrangement is similar to that
shown in Figs. 1 and 2.
As will be obvious my invention is applicable to rails of various forms in cross
section.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A rail joint in which the rail ends are connected by supplementary lengths of
rail arranged to form with each other a tongue and groove or equivalent joint
and each provided with longitudinal extensions or jaws by which it is secured by
suitable fastening devices to the web of the corresponding rail substantially as
herein before described.
2. A rail joint in which the rail ends are connected by supplementary lengths of
rail arranged to form with each other a tongue and groove or equivalent joint
that is supported within a chair to which the jointed parts are connected so as
to permit of expansion and contraction substantially as herein described.
3. My improved rail joint constructed substantially as hereinbefore described
with reference to and shown in Figs. 1 and 2, or modified according to Fig. 3.
