I JOHN CLAYTON MEWBURN, of 169, Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents, do hereby declare the nature of this invention to be
as follows:-
This invention has reference to railway couplings. In the improved coupling, a
hook is formed on the end of a longitudinal bar of from three to four feet long the
inner portion of this bar is screw threaded and receives a long nut. The head of
this nut bears against a spring placed between it and the end cross-beam of the
framing of the vehicle. The nut passes through a worm wheel which is held in a
box. Above this box is a worm or screw on a transverse shaft that extends to the
two sides of the vehicle and is fitted at each end with a handle for turning it so as to
tighten up or slacken the hook. The box is hermetically closed so as to contain oil
and prevent the ingress of dust. The bar of each hook carries a stirrup with link for
the look of the adjoining vehicle to engage with. There is a counterweight to the
stirrup and link and they can be raised or lowered by means of a toothed sector which
gears with a toothed pinion or segment on the stirrup the sector is operated by a
Handle attached to a transverse rod extending to both sides of the vehicle, this:
transverse rod being connected by another rod to the sector.
:
For those cases in which the hook projects through the buffer and the two hooks
meet, a spiral spring is fitted between a flange on the head of the nut and the box
containing the worm wheel.-

page_text: I JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents 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 railway couplings. In the annexed drawings
Figure 1 is a plan and Figure 2 an elevation both partly in section of portions of two
vehicles with the improved coupling fitted thereto. The coupling is constructed as
follows: A hook A is formed on the end of a longitudinal bar of from three to four
feet long the inner portion of this bar is screw threaded and receives a long nut B.
The head of this nut bears against a spring M placed between it and the end cross
beam of the framing of the vehicle. The nut passes through a worm wheel D which
is held in a box. Above this box, and in gear with the wheel D is a worm or
screw E on a transverse shaft that extends to the two sides of the vehicle and is fitted
at each end with a handle F for turning it so as to tighten up or slacken the hook A.
The box is hermetically closed so as to contain oil and prevent the ingress of dust.
The bar of each hook carries a stirrup with link, as shown, for the hook of the
adjoining vehicle to engage with. There is a counterweight to the stirrup and link
and they can be raised or lowered by means of a toothed sector H which gears, as
shown, with a toothed pinion or segment on the stirrup; the sector is operated by a
handle K attached to a transverse rod I extending to both sides of the vehicle, this
transverse rod being connected by another rod to the sector H.
For those cases in which the hooks A project through the buffers and the two
hooks meet, a spiral spring is fitted between a flange on the head of the nut B and
the box containing the worm wheel D.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, as communicated to me, I déclaré
that what I claim is :-
The construction of railway couplings substantially as hereinbefore described and
represented in the annexed drawings.
