of Attaching and Detaching the same.
We, FREDRICK BROUGHTON of 7 Langley Place, Elmers End, Beckenham, Kent,
Engineer, and GEORGE HENRY HALL of Homehurst, Beckenham, Kent, Brewer, do
hereby declare the nature of our invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
These improvements have relation to railway rolling stock and are applicable to
those for which we secured letters Patent No. 6156 dated 6 May 1886.
The present improvements consist in the combination with an inner shackle pivoted
and operated as in Patent No. 6156 of 1886 of an outer shackle pivoted to said inner
shackle and counter weighted and restrained in its movement relative to the first
shackle in such a manner that when the upper shackle is brought up into and over
the horizontal position the counterpoise of the lower shackle is brought into such a
position as to throw the said lower shackle also upward to or somewhat over a
horizontal position, so that on subsequent lowering or releasing of the upper or inner
shackle, the outer shackle falls over the hook of the opposite vehicle.
The annexed drawing shows how the improvements are performed. Figs. 1 and 3
are side views, and Figs. 2 and 4 end views showing the upper shackle or link A and
the lower or balanced shackle B in their normal positions when the vehicle is
uncoupled.
In Figs. 1 and 2 the link A is shown shrunk or keyed on to the operating rod ()
which also is passed through the draw bar hook D. In Figs. 3 and 4 the operating
rod C is shown passing under the draw bar hook and supplied with two forks D' each
shrunk or keyed on to the rod C these forks have each two prongs through or between
which each side of the link A is placed so that on the rod C being operated in the
right direction the forks D' lift up the link A in the position as shown in the dotted
lines Fig. 3 and with it the depending shackle B. The shackle B is furnished with a
counterpoise F as shown and also with a lug G, said lug being so constructed as to
engage in part in a recess formed for the purpose in the link A, the counterpoise F
ID

page_text: keeps the shackle B when in its lower position with the lug against the shackle A as
shown and when the rod C is turned, and the shackle A is thereby lifted into a
horizontal position and by its engagement with the lug G lifts the shackle B in the
same relative position to the shackle A until the said shackle B arrives over the
vertical position. The counter-weight F then operates to throw outward the said
shackle until it arrives more or less horizontally outward over the draw-hook of the
opposite vehicle. A suitable lug may be arranged to prevent the shackle from being
lifted too far above the horizontal line by momentum or otherwise. On now lowering
or releasing the upper or inner shackle, the two shackles fall in the same relative
position and the outer one falls over the said opposite draw-hook and the coupling is
completed.
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 of parts constituting a coupling device, being the rod Cor
equivalent, the shackle A and the balanced shackle B, together with the counter
balance F and engaging lug G all substantially as illustrated and described.
