PROVISIONAL SPECIFICATION.
Improvements in or connected with Railway Rail Joints.
I, FRANCIS WILLIAM WEBB of Chester Place, Crewe, in the County of Chester,
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
My improvement consists of a combined joint chair & splice in halves so arranged
that I get bolts of large sectional area for holding the two halves of the combined
chair & splice together without weakening the web of the rail by drilling or
punching large holes through it. I sometimes supplement the large bolts by two
others of smaller diameter passing through the web of the rail in the usual manner.
In carrying out my invention in the first mentioned way I take a half round piece out
of the web at each end of the rails of sufficient size to enable a bolt to pass through
from one half of the combined joint chair & splice to the other so as to hold them
together. At each end of this combined joint chair & splice I pass a bolt
underneath the rail from one half of the chair to the other & by means of these
three bolts, as described, I hold the two halves of the combined joint chair & splice
together, firmly griping the ends of the rails between them. In the second manner
of carrying out iny invention I, drill or punch a hole in the web of the rail of the
usual size now used for fishplates, at any convenient distance from the end of each
rail & through these holes two bolts may be passed from one half of the combined
chair & splice to the other which would be supplemental to the three larger ones
already described. Immediately under the joint I place a sleeper (by preference of a
larger sectional area than those in ordinary use) to which the combined chair & splice
will be fixed in the usual manner by spikes or bolts or spikes & bolts.

I FRANCIS WILLIAM WEBB of Chester Place, Crewe, in the County of Chester,
Mechanical Engineer 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:-
My improvement consists of a combined joint chair & splice in halves, so arranged
that I get bolts of large sectional area for holding the two halves of the combined
chair & splice together without weakening the web of the rail by drilling or
punching large holes through it. In carrying out my invention I take a piece out of
D

page_text: the web at each end of the rails of sufficient size & shape to enable a bolt to pass
through from one half of the combined joint chair & splice to the other so as to hold
them together. At each end of this combined joint chair & splice I pass a bolt
underneath the rail from one half of the chair to the other & by means of these three
bolts, as described, I hold the two halves of the combined joint chair & splice together
firmly gripping the ends of the rails between them. Immediately under the joint. I
place a sleeper (by preference of a larger sectional area than those in ordinary use)
to which the combined chair & splice will be fixed in the usual manner by spikes
or bolts or spikes & bolts. In the accompanying drawings Fig. 1 shows my improved
joint chair & splice when made of castings, either iron, malleable cast iron or steel,
& suitable for ordinary bull headed rails. Figs. 2 & 3 show cross sections of the
same, the former being taken through the centre bolt C & the latter through the
end bolt C2. The combined chair is formed of two castings A A each of which is
so shaped that it fits tightly against the inclined faces between the top & bottom
flanges of the rails when they are tightly drawn together by the bolts C, C1 & C²
the former bolt C passing through the two halves of the chair & between the abutting
ends of the two adjacent rails D D each of the latter having a semi-circular notch
formed in it to allow the bolt to pass clear throngh. The two bolts C1 C2 pass through
lugs at each end of the chair & underneath the rails as shown in Fig. 3. Fig. 4 is a
plan of my combined chair & splice with the rails D D in position. Figs. 5 & 6
show my combined chair & splice as made out of rolled & stamped plates either of
steel or iron, the method of fastening them together being the same as when made of
castings as above described, the same letters indicating the corresponding parts.
Figs. 7, 8 & 9 show my combined chair & splice as adapted to the "Vignoles" or
flanged rails, the method of securing the parts being the same as above described
& the same letters indicating the corresponding parts. If desired, in addition to the
three bolts already described, I sometimes use two smaller bolts C3, C of the usual
size ordinarily employed with fish plates, each bolt passing through a hole drilled in
the web of the rail at any convenient distance from the end, as shown in Fig. 10.
Such additional bolts would be supplemental to the three larger bolts already
described, but I do not consider these necessary.
Having now particularly described & ascertained the nature of my said
Invention & in what manner the same is to be performed, I declare that what I
claim is:
The improved combined joint chair & splice in halves, wherein three bolts of
large size are employed for securing the parts without weakening the rail by drilling
large holes through the web, substantially as described & shown in the drawings.
