Improvements in Hooks for Coupling and Uncoupling of Coal and
other Corves and the like..
We, HENRY ASKEW, of Stubbin, near Rotherham, in the County of York,
Colliery Manager, and THOMAS SMITH, of Stubbin, near Rotherham, in the County
of York, Carpenter, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements in the making of hooks to couple and
uncouple coal and other corves, tubs, and the like, to be used in and out of coal
and other mines pits and the like whatsoever.
In the construction of this hook, is formed a main corve in hook shape and
also a small hollow which we call a keb and link or chain naturally falls into
this hollow or keb, this is a single hook which is coupled to a link, and uncoupled
by hand and non automatic-and is not riveted or fixed to any plate or pivoted to
any other bearing except a link is welded into the hook-and such link is
welded into the drawbar of the corf and the two vis hook and link hang quite
loose, and suspended from the drawbar of the corf and are coupled to link of next
corf by hand as above named.
This hook may be made of iron steel brass or any other suitable material
whatsoever.

Improvements in Hooks for Coupling and Uncoupling of Coal and
other Corves and the like..
We, HENRY ASKEW, of Stubbin, near Rotherham, in the County of York,
Colliery Manager, and THOMAS SMITH, of Stubbin, near Rotherham, in the County
of York, Carpenter, 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:-
-
Our invention relates to the construction of hooks for coupling colliery corves
and other like vehicles, the object being to provide a hook which will not become
accidentally uncoupled by reason of the jolting and severe shocks to which these
corves or tubs are subjected when in use both above ground and in the pit
workings.
Our invention is illustrated in the annexed sheet of drawings in which
Fig. 1, represents a hook made according to our invention.

page_text: Fig. 2, the ends of the drawbars of two corves with the links and hooks coupled
and understrain.
Fig. 3, shows a position of the engaged hook under a shock which would have
released an ordinary hook.
In carrying out our invention we make a hook A (Fig. 1) approximating in its
main features to an ordinary hook, that is, having a curved hook part B, and an
eye C, to receive a chain link I), which also passes through the eye of the draw-
bar E, shown in Figs. 2 and 3.
In addition to these parts we construct the body of the hook with a projec-
tion F, and with a recess G near the point H, which is slightly curved inwards.
A similar link D2, and hook A2, are connected with the drawbar E2, of the
adjacent corve, each is provided with a set at each end, and when not coupled,
they hang down from the drawbar by gravity.
•*.**..
The links 1 and D2, are made of material that will only just pass through the
mouth of the hook, that is it will pass easily but with very little clearance.
The recess or as it is technically called the "keb "G, is made to correspond with
and receive the end part of the link D, so that when the corves approach each
other from any cause such as a sudden stoppage, and the couplings drop or fall
into any position which would cause an ordinary hook to disengage, the link D2,
will fall into the recess or keb G, as shown in Fig. 3, for example and be pre-
vented escaping from the mouth.
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-A coupling hook for colliery corves, and the like having a retaining recess G,
near the point H, and a projecting part F, opposite the point, as hereinbefore
described and shown.
2 In combination with a link D, carried by the drawbar of colliery corves or
wagons, a hook carried by the said link, and constructed with a recess within
the mouth of the hook, and having the point H, curving inwardly as herein-
before described and shown.
