An Improved Haulage cup.
Year: 1895

page_text: I, JAMES WILLIAM SMALLMAN, of Camp Hill Grange, near 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 enabling tubs or waggons to be
readily attached to and detached from an endless wire haulage rope travelling
continuously.
I prefer to carry out my invention in the following way:-Two side-pieces are
loosely connected by a transverse bolt and nut. The lower portion of each
side-piece has a longitudinal groove (furnished with a steel liner) for the reception
of the rope; the upper portion of each side-piece extending forward. In the top
of one side-piece there works a right-hand screw; a left-hand screw working in the
top of the other side-piece. The heads of the screws project inwardly and are
jointed by pins to lugs on the boss of a hand-wheel placed between the side-pieces.
The coupling for connecting the clip to the tub or waggon may be of any suitable
kind.
The side-pieces are caused to grip the rope by turning the hand-wheel in one
direction and release the rope when the hand-wheel is turned in the opposite
direction.
The right-hand and left-hand screws (instead of screwing into the side-pieces)
may screw into nuts held by the side-pieces, and the screws and hand-wheel may
be cast integrally or be rigidly united.

An Improved Haulage cup.
I, JAMES WILLIAM SMALLMAN, of Camp Hill Grange, near 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 enabling tubs or waggons to
readily attached to and detached from an endless wire haulage rope travelling
continuously.
I prefer to carry out my invention in the following way :-Two side-pieces are
loosely connected by a transverse bolt and nut. The lower portion of each
side-piece has a longitudinal groove (furnished with a steel liner) for the reception
of the rope; the upper portion of each side-piece extending forward. In a nut
at the top of one side-piece there works a right-hand screw; a left-hand screw
working in a nut at the top of the other side-piece. The screws are cut on a
DO1

page_text: shaft which is fixed in the boss of a hand-wheel placed between the side-pieces
The coupling for connecting the clip to the tub or waggon may be of any suitable
kind.
The side-pieces are caused to grip the rope by turning the hand-wheel in one
direction and release the rope when the hand-wheel is turned in the opposite
direction.
The right-hand and left-hand screws may have heads projecting inwardly and
jointed by pins to lugs on the boss of the hand-wheel. Instead of screwing into
nuts, they may screw into the tops of the side-pieces. The screws and hand-wheel
may be cast integrally.
The accompanying drawings illustrate a clip made in accordance with my
present invention.
Fig. 1 is a side elevation of the clip attached to the rope.
Fig. 2 is a corresponding plan; the coupling hook being, however, omitted.
Fig. 3 is a plan showing the clip with the side-pieces not gripping the rope.
Fig. 4 is an end view of the nut held by one of the side-pieces.
Fig. 5 is a corresponding side view.
A and A' are the two side-pieces. B is the transverse bolt furnished with a
nut B'. C are steel liners which fit against the rope D. These liners are inter-
changeable. Each liner is secured by two rivets to the grooved lower portion of
one of the side-pieces. Worn liners can be easily taken out and new ones put in.
E and E are nuts held by the side-pieces. F and F are left-hand and
right-hand screws working in the nuts E and E¹. These screws are cut on a
shaft which is fixed in the boss of a hand-wheel G. The nut E has V-shaped
projections e which rock against the top of the side-piece A. H is a rivet that
passes through a hole ex in a projection e' on the nut E. This rivet merely
serves to keep the nut in the side-piece. There should be plenty of play between
said rivet and the hole ex. The nut E is prevented from turning by the pro-
jection. The nut E' corresponds with the nut E and is retained in the
side-piece A by the rivet H'. a and a are projections which lie on the rope and
support the clip until the side-pieces have been caused to grip the rope; these
projections greatly facilitating the manipulation of the clip. J is a coupling hook
for connecting the clip to the tub or waggon. The clip is adjusted to fit any
particular rope or to compensate for wear by turning the nut B¹. The holes in the
side-pieces through which the bolt B passes are rectangular. The bolt B has a
Equare neck and the head of the bolt may be on either side of the clip.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim :-
1. The improved haulage clip made or operating substantially as described.
2. In a haulage clip, the combination, with two side-pieces and a transverse
bolt and nut loosely connecting said side-pieces, of right-hand and left-hand screws
and a hand-wheel for causing the screws to act on the tops of the side-pieces,
substantially as set forth.
3. A haulage clip comprising two side-pieces the upper portions of which extend
forward, a transverse bolt and nut loosely connecting said side-pieces, nuts held
by the said side-pieces, right-hand and left-hand screws engaging with the nuts
held by the said side-pieces, and a hand-wheel united to the screws, substantially as
described.
