PROVISIONAL SPECIFICATION.
Improvements in or relating to Clips for Rope Railways.
I, DANIEL LONSDALE of Abbott Street, Awsworth, in the County of
Nottingham, Enginewright, do hereby declare the nature of this invention to be
as follows:-
This invention relates more especially to clips for attaching tubs, corves, or the
like, hereinafter called tubs, to the rope of rope railways in mines or other
works.
Clips of this description are usually formel with a hook at their upper end to
engage with an eye in the draw-head of the tub.
In carrying out my invention the hook is preferably hinged to the main part so
that it will turn over in the direction of the length of the rope so as to release the
tub or corve the hook may be held in its normal position by a pin passing through
the hinge-joint parallel to the axis the sleeves of bosses of the hinge being
preferably of unequal diameter so that the pin will pass through holes in the
bosses of one part and engage in recess in the bosses of the other part.
With this arrangement when the tubs run off the road the increased strain will
break or cut the pin the book will turn over and the tub will be at once released.
The advantage of this over existing arrangements is that the clip can be repaired
by inserting a fresh pin whereas with a fixed hook the hook is pulled off and is
only repaired by welding a fresh one on in its place.
It is obvious that modifications of the arrangement for attaching and securing
the hook to the clip may be employed without departing from the spirit of the
invention.

COMPLETE SPECIFICATION.
Improvements in or relating to Clips for Rope Railways.
I, DANIEL LONSDALE of Abbott Street, Awsworth, in the County of
Nottingham, Enginewright, 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 more especially to clips for attaching tubs, corves, or the
like, hereinafter called tub, to the rope or rope railways in mines or other
works.
It will be best understood by reference to the accompanying drawings in
which
Figure 1 is a side and Figure 2 an end elevation of a clip constructed according
to my invention.
Figure 3 is a side elevation of the upper portion of the clip showing the hook
turned back.
Like letters indicate like parts throughout the drawings.
The invention as described and shown is applied to a clip of ordinary con-
struction, provided at the upper end with a hook adapted to engage with the
draw bar of a tub or the like, and at the lower end with two jaws A, formed with
recesses to fit on the haulage rope the jaws A are caused to clasp the rope by the
action of the sliding sleeve A' which embraces both jaws.
Pin d
;

page_text: The hook or part a for attaching the clip to the draw bar of the tub, is
preferably pirotted or connected as shown by a knuckle joint to the main part of
the clip at , so that it will turn over in the direction of the length of the haulage
rope and release itself from the draw bar of the tub. The hook a may be held
in its normal position as shown in Figures 1 and 2 by a pin d fitting in corresponding
holes in the parts a' e a' forming the knuckle joint the holes being preferably
parallel to the axis of the joint.
With this arrangement when the tubs run off the road or meet with an obstacle
the increased strain on the hook a will cause the joint to break or cut the pin d and
allow the hook a to turn over as shown in Figure 3 and release itself from the
draw bar of the tub.
The advantage of this over existing arrangements is that the clip may be at
once repaired by inserting a fresh pin d whereas with a fixed hook it is pulled
off and the clip can only be repaired by welding a new one on in its place.
To adapt the clips for drawing different loads, holes having different diameters
may be formed in the knuckle joint to receive pins of different strength, or the
holes may be formed at different distances from the centre of the joint.
It is obvious that modifications of the arrangement described for attaching and
securing the hook to the clip may be employed without departing from the spirit
of the invention, for example the hook may be secured to the clip by two or more
pins such as d and either or both may be broken or cut and the clip pulled clear
away from the hook.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with a clip for rope railways of a pivotted or detachable
hook or part for attaching the clip to the draw bar of the tub substantially as
and for the purpose herein described.
2. The combination with a clip for rope railways of a hook such as a pivotted to
the main part substantially as and for the purpose described and illustrated in the
accompanying drawings.

LONSDALE.
