PROVISIONAL SPECIFICATION.
An Improved Rope Carrier for use in connection with Rope
Haulage Clips.
WILLIAM DENNIS HODGKINSON Miner &c. Parish of Newthorpe Nottingham-
shire do hereby declare the nature of this invention to be as follows:-
To be used in haulage in connection with clips. To be the said clip's assistant,
companion, friend, and burden bearer.
"Carrier" is attached at one end of wagon clips at other end of wagon.
"Carrier" is not to take the place of clips by hauling the load, but to carry the
rope high enough so as not to burden the clips by the downward or side pull, which
in many cases is far more than hauling the load.
"Carrier" carries rope, assists in haulage and acts as a brake in steadying load,
in case clips become detached.
Carrying the rope is quite as necessary as hauling the load.
"Carrier" to be made of iron or steel. Length, over all 5 in. to 8 in. varying in
length to clips used. Diameter, in. to in. which may be round or square,
according to work. Is from 2 in. to 34 in. shorter than clips, so as to receive the
downward pull, will have two hooks, & bow or handle, or three hooks and no
handle. The handle will be at top of "carrier." If three hooks are used, the one
not in use, will take the place of handle.
The bottom hook (passing under the rope) is 3 in. to 4 in. long (this being one
of the special features).
The book is carried up high enough so as the rope cannot get over the
top of same, the rope cannot travel or rise higher than the under side of tram
axles, so that this bottom hook will be quite as high as the top side of tram axle.
The rise & fall of the rope, is caused by the gradient of the roads varying; if
passing through a valley or between two hills, the rope rises, or the road lowers,
which brings the axles of tram, or wagon down on to the rope.
When the load is passing over a hill, the rope is bearing down, & even though
the top of the said bill be flat, it gives the clip much more work than hauling the
load up a steep hill or incline.
It is here that the "carrier" is needed. If the road has an equal gradient, then
the said "carrier" carries the rope all the way. It is the uneven gradient which
requires the hook to be made longer, being brought higher than the rope can rise,
otherwise the hook would swing from under the rope and cease to act.
When a
light load is being hauled over a hill, the opposite end to that clipped is lifted off
the rails which looks like a man having a pair of yokes, with a bucket of water at
one end only; but clipped at one end and "carrier" at the other end looks like
the said man with yokes and two buckets of water balanced. The "carrier" being
shorter than clip always takes the downward pull.
The top hook, or hooks, is to hang on the tug or tram iron (which passes from
one end of tram to the other) and is about 1 inch long.
This short hook is short because a long hook could not be hung on, hence the
necessity of being short. There is generally a margin of from 14 in. to 24 in. for
putting on and taking off; this margin is obtained by lowering the rails 3 in. to
4 in. which brings the tram axles down on to the rope. This lowering is
done both at clipping on station and station for taking "carrier" off. The rails
at clipping on station are lowered for clipping, which answers for hanging
" carrier on.
In case three hooks are used instead of two hooks and bow or handle there are
two short top hooks, and one long bottom hook.

page_text: Both the top hooks are about 1 inch long and are on opposite sides to each other
one being inch higher than the other. This is to meet the varying distance
between the rope and tug irons; one top hook only being used at once, except when
the spare hook is being used as the handle.
This carrier" reduces the rise and fall of rope; the limit of the rise being the
axle, and the limit of fall the base of bottom hook.
If the top hooks must be changed, through the one being too long or too short,
the bottom hook will be on the reverse side of the rope.
The long bottom hook is hung on first and the short top hook last, and in taking
off vice versa.
The lowering of rails 3 in. to 4 in. giving ample margin for taking the short top
hook off as the long bottom hook lowers from the rope allowing "carrier" to be
taken off at top hook by lifting "carrier" up out of tug iron & lowering to allow
bottom long hook to fall from under the rope.

COMPLETE SPECIFICATION.
An Improved Rope Carrier for use in connection with Rope
Haulage Clips.
I, WILLIAM DENNIS HODGKINSON, of Newthorpe, in the County of
Nottingham, Miner and Ironmonger, 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 :-
My invention relates to an improved rope-carrier for use in connection with the
rope haulage clips of the kind described in the Specification of former Letters
Patent granted to me No. 7996 of April 28th 1892, or with other clips of similar kind.
In working rope haulage systems in mines it is well known that when the corves
or waggons are passing over a hill the rope pulls downwards heavily and puts a
strain upon the haulage clips which in many cases is greater than that which is
necessary for hauling the load and in cases where a light load is being hauled over
a hill the opposite end of the waggon from that to which the clip is attached is
frequently lifted off the rails owing to this downward pull.
The object of my invention is to provide means for carrying the rope indepedently
of the haulage clip, whereby the downward pull is obviated and whereby, in case
the haulage clip becomes detached from the rope or waggon, the load will be more
or less steadied and to a certain extent retarded in case of running down an incline.
My improved carrier is provided with two hooks, namely, one for suspending it
from the corve or waggon and the other for carrying the rope, this latter hook
being made of considerable length so as to allow the rope to rise and fall therein
according to the gradient of the road without becoming detached from the hook.
The said carrier is also provided with a handle for manipulating it or with a second
Buspension hook which serves as a handle.
To enable my invention to be fully understood I will describe the same by reference
to the accompanying drawings, in which :-
Figures 1 and 2 are elevations at right angles to each other of a carrier provided
with two hooks and a handle; and,
Figures 3 and 4 are also elevations at right angles to each other of a carrier
provided with a third hook.
Similar letters of reference indicate corresponding parts in the several figures.
a is the shank of the carrier, b a small hook formed at the upper end of the shank
and by means of which the carrier is suspended from the corve or waggon,
and c the hook formed at the lower end of the said shank and serving to carry the
rope. is the handle by means of which the carrier is connected with and
disconnected from the waggons.

page_text: The length of the carrier will vary according to the length of the haulage clips
in connection with which the carrier is used but in all cases the carrier will be shorter
than such clips (say from two inches to four and a half inches shorter) so that the
weight and downward pull of the rope will be carried and supported by the carrier,
whereby the clip will only have to bear the hauling strain.
The lower hook c of the carrier is of such length that when suspended from the
waggon its upper end will be above the level of the under sides of the axles so that
in passing across a valley the rope shall not lift out of the said hook but come to
bear against the said under sides of the axles.
e, Figures 3 and 4, represents the hook which I sometimes employ in addition to
the hook b, such hook being placed lower down the shank a than the hook so that
the said carrier may be used in conjunction with clips and tug-irons of varying
lengths one or the other of such hooks b, e being employed according to the length
of clips and tug-irons.
In applying the carrier the hook c is first engaged with the haulage rope and
then the carrier is lifted to engage one or other of the hooks b, e with the tug-iron
of the waggon at the opposite end to that carrying the haulage clip.
By using my improved carriers I am enabled to employ haulage clips of much
lighter construction than would be necessary if such clips had to support the weight
and downward pull of the rope in addition to the haulage strain.
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. A rope-carrier having two hooks and a handle by means of which the carrier
may be manipulated, one of the said hooks serving for suspending the carrier and
the other for receiving the rope, the latter hook being of such length that the rope
will be prevented from becoming disengaged therefrom, substantially as described.
2. A rope-carrier having more than two hooks, one of which is of such a length
that when the carrier is suspended it will prevent the rope from becoming disengaged
therefrom whilst the others serve for suspending the said carrier, substantially as
described.
3. The manufacture and use of rope-carriers to be employed in connection with
rope haulage clips substantially in the manner hereinbefore described and illustrated
in Figures 1 and 2 and in Figures 3 and 4 of the accompanying drawings.
