PROVISIONAL SPECIFICATION.
A Double Automatic Coupling for Railway Vehicles.
JAMES BENJAMIN SYKES, 12A, East Parade, Huddersfield, Yorks., Manufacturer,
and WILFRID EWART SYKES, 33, Arnold Street, Birkby, Huddersfield, Yorks.,
Teacher, do hereby declare the nature of this invention to be as follows:-
An automatic coupling which couples on impact, the cross-bar K striking
bar A which moves away freely round B (Fig. 2) and falls back again into
first position enclosing K (Fig. 1) which can only be released by dropping of
part E as shown in Fig. 3.
Fig. 4 is a side elevation and Fig. 5 a plan of moving parts by which A is
released.
Figs. 6, 7 and 8 shew alternative method of moving bar Q by means of levers.
Fig. 9 shews plan and Fig. 10 sectional elevation of alternative method of
moving parts by which A is released.
The two parts of the coupling are arranged laterally on each end of waggon.

A Double Automatic Coupling for Railway Vehicles.
JAMES BENJAMIN SYKES, 12A, East Parade, Huddersfield, Yorks., Manufacturer,
and WILFRID EWART SYKES, 33, Arnold Street, Birkby, Huddersfield, Yorks.,
Teacher, 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 relates to the construction of an automatic coupling which
couples on impact the crossbar K (Figs. 1, 2 & 3) striking bar A (Fig. 3) which
moves away freely round pin B (Fig. 3) and falls back again into first position
enclosing K (Figs. 1 and 3). The further impact of parts of coupling is pre-
vented by that of the buffers which thus take all the strain. To enable the bar K
to strike bar A when couplings are at different heights bar A itself is made of
sufficient length and inclined plane G (Figs. 1, 2 & 3) is used, up which K may
be forced, the arms H, H moving about hinge M (Fig. 3).
The bar A can only be released by the dropping of plate E shown in Figs. 5,
6, 9, 10.
On the back of E (Fig. 6) is a rack worked by a cogged wheel T (Fig. 6) in
its turn worked by lever Q (Fig. 6) and rotating arm F F (Fig. 5) fixed on
waggon end.
This lever Qmay be worked by straight levers instead of rotating rod, as
shewn in Fig. 7. Part E may be lowered by a cogged wheel X (Fig. 10) work-
ing inside part E (Fig. 10) by means of rotating arm and cogged wheels V &

page_text: Was shewn in Fig. 9. To enable coupling to work easily on extreme curves
two rods R R (Fig. 4) are fastened into the back L of coupling and passing
through end of waggon have springs ZZ attached as in Fig. 4 so that when
coupling is turned about pin S (Fig. 4) it is brought back to its normal position
at right angles to the waggon end. The curved back L has a small flat portion
in centre of curve adjacent to waggon. C is the bar in end of which A is sus-
pended, D the framework in one end of which part E slides and P one back
plate of coupling holding parts C and D.
Fig. 1 shews coupling (plan) when coupled on a straight line.
Fig. 2 shews coupling (plan) when coupled on an extreme curve.
Fig. 3 shews side elevation of half of coupling.
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: -
1. The combination of movable pin and inclined plane to allow of coupling
with waggons of different heights.
2. The method of uncoupling by means of movable part E as shewn in
drawings.
3. The combination of the parts in such dimensions as to allow for variation
in length of buffers.
4. Arrangement as shewn in Fig. 4 enabling coupling to adapt itself to run-
ning on extreme curves by horizontal rotation round end of drawbar.
5. Method by which coupling regains (when released) its normal position at
right angles to waggon end viz. by means of the two springs Z Z and curved
back L which has a flat portion in centre of curve as shewn in Fig. 4.
