AN IMPROVED HAULAGE CLIP
Year: 1884

page_text: I, JAMES WILLIAM SMALLMAN, of Camp Hill Grange, Nuneaton, in the County
of Warwick, Mining Engineer, do hereby declare the nature of my invention for
"AN IMPROVED HAULAGE CLIP" to be as follows:-
I use two side pieces of the ordinary well known form, tightened by a central.
screw. The object of my invention is to do away with the necessity for turning
the screw to detach the clip. I accomplish this; end by using a binged packing
plate, so shaped that the clip may be unfastened by simply knocking this plate
from under the head of the screw. Several turns of the screw are by this means
rendered unnecessary in tightening the clip on the rope. The packing plate, upon
which a lever.may be left, may turn about the rivet or pin used to secure the clip
to the ring or chain for attachment to the tub
If preferred, the screw may be provided with a nut. When the clip is secured
to the rope, either the head of the screw or the nut, must rest on a lump or
projection at the end of a slot in one of the side-pieces. The clip can then be
detached from the rope, by knocking the head of the screw or the nut off the.
aforesaid lump or projection.
A wedge may act on a sliding or hinged packing plate, or on a solid lump or.
projection on one of the side pieces, after the same manner as the screw, and
may be used instead of the same.
Acting in combination with a central screw or wedge, a packing plate may be.
inserted between the side pieces at the top of the clip. When this packing plate
is removed, the side pieces are brought further away from each other at the bottom,
so that the clip may be readily detached from the rope

SPECIFICATION.
I, JAMES WILLIAM SMALLMAN, of Camp Hill Grange, Nuneaton, in the County
of Warwick, Mining Engineer, do hereby declare the nature of my invention for
"AN IMPROVED HAULAGE CLIP" and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:—
My invention relates to an improved clip for attaching tubs or corves to endless
wire haulage ropes in motion, or for other similar purposes.
I will at once proceed to explain my invention with reference to the accompanying
drawings. The same letters indicate similar parts in all the Figures.
I use two side pieces A, A¹, of the ordinary well known form, tightened and held
together by a central screw B. The object of my invention is to do away with the
necessity for turning the screw B to detach the clip. I accomplish this end by
using a wedge shaped packing plate P hinged to the clip, as shewn in side elevation
in Figure 1, and end elevation in Figure 2. Several turns of the screw B are by
this means rendered unnecessary in tightening the clip on the rope R. The clip is
shewn unfastened in Figures 3 and 4. The packing plate P, on which the lip C
may be left, may turn about the rivet E, used to secure the clip to the ring F, for
attachment to the drawbar of the tub. A catch affixed to a guide placed between
the rails, may engage with the lip or projection C, and withdraw the packing plate P
from under the head of the screw B, thereby detaching the clip automatically, as
will be readily understood. A lever L may be left upon the packing plate P, as
shown in Figures 5 to 8, both inclusive. The spanner used to tighten the screw B
may then be used to strike the lever L, in order to unfasten the clip. The packing
plate P, in addition to the lever L, may have the lip or projection O, shewn in
Figures 1 to 4, both inclusive.
If preferred, the screw may be provided with a nut, as in Figures 9 to 13, both
inclusive. The head of the screw B may be hinged to the side piece A by means
of the rivet D, Figures 10, 11, and 13. When the clip is secured to the rope, the
nut must rest on a lump or projection P¹ at the end of a slot in the side piece A¹,
as shown in side and end elevation in Figures 9 and 10, and in sectional elevation
in Figure 11. When the nut is removed off the aforesaid lump or projection P³,
the side pieces A, A¹, open at the bottom and liberate the rope R, as shown in side
and end elevation in Figures 12 and 13. It is obvious the clip may be so modified
that the head of the screw may rest on the lump or projection P¹, instead of the
nut. The rivet D would then be dispensed with. The lump or projection P¹, on
the side piece A¹, acts as packing; the lump H, on the side piece A, does not.
Both side pieces may be slotted, if preferred, and the head of the screw and the
nut may each rest on packing. This clip is intended to be detached automatically,.
by means of a modification of the arrangement described and illustrated by James
Pease, in his Specification No. 3351, AD. 1878.
Figure 14 is a section through the line Z Z, Figure 9, showing the studs cast on,
or rivetted to, the side pieces A, A¹, in order to prevent the rope getting above the
longitudinal grooves made in the aforesaid side pieces to receive it.

page_text: The packing arrangement may be on the one side of the clip, and the tightening
arrangement on the other side. A wedge may act on a sliding or hinged packing
plate, or on a solid lump or projection on one of the side pieces, after the same
manner as the screw, and may be used instead of the same.
Acting in combination with a central screw or wedge, a packing plate P* may be
inserted between the side pieces A, A¹, at the top of the clip, as shewn in side and
sectional elevation in Figures 15 and 16, and in plan in Figure 17. When the
packing plate P³ is removed, the side pieces A, A', open at the bottom, so that the
clip may be readily detached from the rope, as shewn in side and sectional elevation
in Figures 18 and 19. In Figures 20 to 24, both inclusive, the packing plate P* is
pivoted about the central screw B; in Figures 25 to 28, both inclusive, a similar
clip is shewn, but the rigid link G is substituted for the ordinary ring F. Any
other suitable form of coupling may be used, and attached to the clip in any
convenient position. The packing plate P with the lever L attached, as illustrated
in Figures 20 to 28, both inclusive, is shown in side elevation and plan in Figures 29
and 30. It is obvious a first order lever may be substituted for the second order
lever illustrated in Figures 15 to 30, both inclusive. This form of clip is intended
to be detached by hand.
I wish it to be distinctly understood that I do not limit myself to packing of
any particular shape, nor to any particular lever, nor to the precise details herein
described and illustrated in the accompanying drawings, as the same may be varied
without departing from the principle of my invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
(1) Making a screw clip so that, without turning the screw, it may be detached
from the rope.
(2) Using any form of packing, whether a solid portion of a side piece or not,
under a part of the screw, or anything in connexion with the screw, in a screw
clip; or under a wedge in a clip that is tightened by means of a wedge; or acting
between the side pieces in combination with a central screw or wedge, substantially
for the purposes hereinbefore set forth.
(3) The improved principle of haulage clip, and the arrangement and combination
of the parts, substantially as described and illustrated in the accompanying
drawings, or any mere modification thereof.
