I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a coupling for cars running on rails and for similar
purposes. The coupling according to this invention is characterised by its sim-
plicity and the reliability of its working as compared to the hitherto known
couplings.
A spring hook is secured to one car or part to be coupled and engages with a
hook of the other car or part. This hook is connected to a short link connected
to a crank operated by means of a handle. When it is desired to close the
coupling, the handle is moved say upwards, which brings the crank outwards
into a horizontal position and advances its hook. If the hook of the other part
is now placed in the crank hook and the handle turned down, the crank will be
caused to turn and draw the hooks inwards pulling the cars or parts together.
The two hooks thus become housed in a suitable recess in the framing or casing
which is so shaped as to hold them close together and prevent their disengage-
ment. The link is preferably provided on its lower side with one or more hook
shaped projections which when the coupling is closed engage with corresponding
recesses in the framing or casing and thus relieve the strain on the crank.
The crank hook is made sufficiently wide so as to enable the other hook to move
as much as necessary on curves without becoming disengaged from it.
The handle may be secured in its position when the coupling is closed by
means of a pawl or by other suitable means. When applied to railway cars or
trucks each car may be provided at each end with a crank hook and a spring hook
to engage with corresponding hooks on the other car.

'A communication from DIRK KOELEMAN, Manager, of 46/48, Anna Paulowna-
straat, Hague, in the Kingdom of Holland.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a coupling for cars running on rails and for similar
purposes. The coupling according to this invention is characterised by its sim-
plicity and the reliability of its working as compared to the hitherto known
couplings.
A coupling according to this invention is illustrated in the accompanying
drawing, in which
Figure 1 shows it open, or out of action, and
Figure 2 closed.
Figure 3 being a plan of Figure 1.
A spring hook A is secured to one car G or part to be coupled and engages with a
hook B of the other car or part G. This hook B is connected to a short link C
connected to a crank D operated by means of a handle E. When it is desired to
close the coupling, the handle E is moved say upwards, which brings the crank D
outwards into a horizontal position and advances its hook B. If the hook A or
the other part is now placed on the crank hook B and the handle E turned down,
the crank D will be caused to turn and draw the hooks inwards pulling the
cars or parts together. The two hooks A and B thus become housed in a suitable
recess in the framing or casing (Figure 2) which is so shaped as to hold them
close together and prevent their disengagement. The link C is preferably pro-
vided on its lower side with one or more hook shaped projections which, when
the coupling is closed, engage with corresponding recesses in the framing or
casing and thus relieve the strain on the crank (Figure 2).
The crank hook B is made sufficiently wide so as to enable the other hook
to move as much as necessary on curves without becoming disengaged from it.
The handle E may be secured in its position when the coupling is closed, by
means of a pawl or by other suitable means. When applied to railway cars or
trucks each car may be provided at each end with a crank hook A and a spring
hook B to engage with coupling hooks on the other car.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed I declare that what I claim is :-
1. A coupling for cars and for similar purposes comprising a spring controlled
hook on one of the parts to be coupled adapted to engage with a hook on the
other part, the latter hook being connected by a link with a crank provided with
an operating handle or lever whereby the hook may be drawn into a recess in
the casing, substantially as described.
2. In a coupling of the character described projections or teeth on the link

page_text: engaging with corresponding recesses in the casing for the purpose of relieving
the crank from strain.
3. The complete coupling described or illustrated in the accompanying drawings.
