TROYIDIUNAD DI MUITTUATION.
An Improved Haulage Clip.
I, JAMES WILLIAM SMALLMAN, of Nuneaton, in the County of Warwick,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved clip for connecting tubs or waggons to
endless wire haulage ropes.
In carrying out my invention, I employ a bar having at one end a hook or ring
for attachment to the tub or waggon and formed at the other end with jaws between
which the rope is gripped owing to the kink put into the rope by the weight of the
load acting on the hook or ring. The jaws are prevented from leaving the rope by
a collar having a projection or projections lying across the jaws when the collar is
in its lowest position. The bar may be furnished with a stud or split pin for
retaining the collar.
1
To attach the clip, the collar is raised and the clip swung laterally until the rope
is between the jaws, whereupon the collar is allowed to fall into its working position.
The clip can be readily detached by hand. If the collar is raised by a mechanical
unclipper, an incline is provided for subsequently pressing the bar laterally away
from the rope.
The clip described above is exceedingly simple and easy to repair, and can be
manipulated with one hand.

JAMES W. SMALLMAN.
An Improved Haulage Clip.
I, JAMES WILLIAM SMALLMAN, of Nuneaton, in the County of Warwick,
Engineer, 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 an improved clip for connecting tubs or waggons to
endless wire haulage ropes.
In carrying out my invention, I employ a bar having at one end a hook or ring
for attachment to the tub or waggon and formed at the other end with jaws
between which the rope is gripped owing to the kink put into the rope by the
weight of the load acting on the hook or ring. The jaws are prevented from
leaving the rope by a collar having a projection or projections lying across the jaws
when the collar is in its lowest position. The bar may be furnished with a stud or
split pin for retaining the collar.
To attach the clip, the hook or ring having been coupled to the tub or waggon,
the collar is raised and the clip swung laterally until the rope is between the jaws,
whereupon the collar is allowed to fall into its working position. The clip can be
readily detached by hand. If the collar is raised by a mechanical unclipper,
an incline is provided for subsequently pressing the bar laterally away from the
rope.
The clip described above is exceedingly simple and easy to repair, and can be
manipulated with one hand.

Fig. 1 shows in side elevation a clip made according to the way in which I prefer
to carry out my invention.

Fig. 4 is a side elevation of the bar.
Fig. 5 is a corresponding end elevation.
Fig. 6 is an end elevation of the collar.
Fig. 7 is a side elevation illustrating a modification of the clip.
Fig. 8 is a view corresponding with Fig. 7; the bar being in end elevation and
the collar in section.
Fig. 9 is a diagram representing in plan the device used for automatically
detaching the clip.
A is a bar having a hook B for attachment to the tub or waggon and jaws C
and D for kinking the rope E. F is a collar with a projection G. This projection
is deep enough to lie across the jaws. There is consequently no probability of
the collar being accidentally raised high enough to permit the jaws to leave the rope.
The projection, while taking the lateral strain exerted upon it by the rope at a
curve, is supported in turn by each of the vertical rollers.
In order to lighten the clip, a groove or channel A* may be formed in the bar.
In the modification shown in Figs. 7 and 8, the collar F has two projections G¹
instead of the single projection G; a lump D¹ on the jaw. D lying between the
projections. N is a stud for retaining the collar F.
Hand K are trunnions on the collar F for engaging with the inclined plates L
and M of the mechanical unclipper illustrated in Fig. 9. The trunnion H slides
up the plate L and the trunnion K up the plate M. The collar then runs along
an incline on a horizontal plate L'; the trunnion H extending over that plate and
supporting the collar. This incline forces the collar and consequently the bar
laterally away from the rope E; thus detaching the clip.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I claim :-
1. For connecting tubs or waggons to endless wire haulage ropes, the improved
clip, adapted for detachment by hand or by means of a mechanical unclipper,
substantially as described with reference to the accompanying drawings.
2. For connecting tubs or waggons to endless wire haulage ropes, a clip adapted
for detachment by hand or by means of a mechanical unclipper and comprising a
bar having jaws for kinking the rope, a collar sliding on the bar, and a projection
or projections on the collar lying across the jaws, the collar and projection or
projections serving to prevent the jaws leaving the rope, substantially as herein
described.
