Improvements in Haulage Clips.
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 haulage clips for connecting tubs or waggons employed
in conveying coal or other minerals to endless wire haulage ropes in motion.
The extensively-used "Smallman" clip is detached by raising a lever, which
lever constitutes part of the clip. This clip is attached by depressing the lever,
and then, if necessary, tightening a central screw with a spanner; the end of the
short arm of the lever lying between the side-pieces and being in the form of a
wedge. The central screw serves as the fulcrum for each side-piece, and enables
perfect adjustment to be attained.
It is sometimes desirable to have a coupling which, instead of being free to
oscillate on the coupling-pin, is connected to the clip in such a manner as to prevent
any oscillatory movement.
The object of this invention is to utilize the central screw for preventing the
oscillatory movement of the coupling.
My invention consists in extending the coupling-plate between the side-pieces,
and passing the central screw through a hole in the extension; thus connecting
the coupling to the side-pieces at two points some distance apart-that is, at the
coupling-pin and at the central screw. Trunnions on the coupling-plate may,
however, be used instead of the coupling-pin.

COMPLETE SPECIFICATION.
Improvements in Haulage Clips.
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 haulage clips for connecting tubs or waggons employed
in conveying coal or other minerals to endless wire haulage ropes in motion.

Fig. 1 is a side elevation of
invention.
Fig. 2 is a similar view with the right-hand side-piece removed; the coupling-
pin, the central screw and one of the lever-trunnions being in section.
& Smallman clip embodying the present
Fig. 3 shows a different design wherein the lever is locked by the coupling.
Fig. 4 representing the coupling in that position in which it does not prevent
the raising of the lever.
The well-known "Smallman" clip is detached by raising a lever A A', which
lever constitutes part of the clip. This clip is attached by depressing the lever
and then, if necessary, tightening a central screw B with a spanner; the end of
the short arm A of the lever lying between the side-pieces C and C¹ and being
n the form of a wedge. The head of the central screw B serves as the fulcrum for
he side-piece C, and the nut as the fulcrum for the side-piece C¹; the central
crew thus enabling perfect adjustment to be attained. The coupling is usually a
look on the end of a plate provided with an eye through which a coupling-pin E

the rope.
It is, however, sometimes desirable to have a coupling which, instead of being
free to oscillate on the coupling-pin, is connected to the clip in such a manner as to
prevent oscillatory movement.
The object of this invention is to utilize the central screw for preventing the
oscillatory movement of the coupling.
My invention consists in extending the coupling-plate D between the side-
pieces C and C', and passing the central screw B through a hole in the
extension D¹; thus connecting the coupling to the side-pieces at two points some
distance apart-that is, at the coupling-pin E and at the central screw B.
Trunnions on the coupling-plate D D' may be used, if preferred, instead of the
coupling-plate E.
In Figs. 3 and 4, sufficient play is allowed in the hole in the extension D¹
to enable the coupling to lock the lever A A¹. In Fig. 3, the coupling is in
the position it assumes when the clip is pulling the load; an enlargement G on the

extension D' being in the path of a projection H on the lever.
enlargement is in the path of the projection, the lever can not be raised to release
the clip. In Fig. 4, the coupling is in the position it can assume when the clip is
not pulling the load; the enlargement G being out of the path of the projection H.
When the enlargement is out of the path of the projection, the clip can be readily
detached by raising the lever.
A coupling connected to the side-pieces at two points supports the clip better
than a coupling which is free to oscillate on the coupling-pin, and it also keeps the
rope off the axle of the tub or waggon.
Instead of a hook K on the coupling-plate D D³, a ring or other device adapted
to engage with any particular drawbar on the tub or waggon may be employed;
the hook K being shown by way of example only.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I claim :-
1. The improved coupling for haulage clips substantially as described with
reference to the accompanying drawings.
2. In a haulage clip, the combination, with side-pieces C and C¹ and a central
screw B which serves as the fulcrum for each side-piece, of a coupling arranged
between the side-pieces and held by a coupling-pin E (or trunnions) and by the
central screw B, substantially as herein set forth.
3. In a haulage clip, the combination, with side-pieces C and C¹, a central
screw B which serves as the fulcrum for each side-piece, and a lever working
between the side-pieces for attaching and detaching the clip, of a coupling arranged
between the said side-pieces and held by a coupling-pin E (or trunnions) and by
the central screw B, substantially as herein set forth.
