Improvements in Haulage Clips and Drawbar Attachments for Rope
Haulage.
I, WILSON GRAHAM, 7, Bransty Villas, Bransty, Whitehaven, Cumberland,
Colliery Overman, do hereby declare the nature of this invention to be as
follows:-
1 construct of cast steel and forged iron, my "improved clip and drawbar
attachment," by means of which when fixed single tubs, or trams, or trains of
tubs or trams, may be easily and safely moved from place to place, on a rope
haulage system, by the labour of one boy only, and I construct them in the
following manner, viz. :-
I make in cast steel or iron (by preference mild steel) the body of my clip, (any
size to suit requirements) in the present case, size about 12 in. deep over all, curved
from 3 in. from top, to throw the front part forward to project in front of tram
some 6 in. My clip has double jaws at the top, above the curve, in. thick,
23 in. deep and a 4 in. pin hole in centre, (by means of which the clip is fixed on to
the drawbar) from the bottom of the jaws, the clip is curved, & solid for about 4 in.,
and 1 in. by 24, when a box is formed in the centre, the sides of which are about
gin. thick, 2 in. deep, with a gin. pin hole in the centre, the box being about
4 in. deep, (front view) the inside of this box is shaped like a double triangle, the
V points facing each other.
Inside this box the lever, or levers, are worked.
From the bottom of this box, the body gradually thickens again, and is again
curved forward, and another box is formed at the bottom of the clip, leaving side
opening for the rope being shipped or unshipped tg in., this box can be either single
or double, to admit of either single or double wedges being used. This box
looking at it from the front resembles the letter G, and it is tapered inside to suit
the wedge.
If for single wedge, the butt of the wedge goes into box from the rear, if for
double wedge, both wedge points approach each other in the centre of the box, one
entering from the front, and the other from the rear simultaneously, the curve of
this box leaves about in. to 1 in. material.
The above represents roughly the cast or moulded part of my clip. Into which
at the triangular shaped box a lever, or levers, 1 by , curved to suit, is fitted
with suitable wedge, or wedges, which are shipped into the bottom box, outo the
rope at will, by simply striking or raising the lever as required.
If for single wedge one lever lifts, or replaces it.
If for double wedge, one lever does for both, by an arrangement of half moon
toothed cogg, in the triangular shaped box, thus by the action of one lever both
wedges are raised or lowered into position, simultaneously.
The wedges are tapered to suit the box, and grooved on the under side to suit
the rope, and are drawn firmly into position by the action of the rope when in
motion.
The draw-bar is constructed of mallable iron, to suit, in the present case about
4 ft. 3 in. over all, about 3 in. broad, (flattened horizontially) except at point
about 6 in. from each end a space about 2 in. square, & in. thick, flattened and
dressed vertically, is left, betwixt the coupling or crook, and body of tram, onto
this the clip is fixed with pin, and held firmly & rigidly in position.

page_text: The drawbar is attached to the tram with 3 ordinary in. square necked bolts,
or suitable eyebolts may be utilised if made to suit the jaws of my clip, this will
save the cost of altering drawbars, at collieries &c. where the plant is already
down.
My clip and drawbar attachment, are in the aforementioned notes roughly
described, and their distinctive features are, that the invention is easily handled,
"a boy can put it on or take it off."
The greater the weight behind it, the firmer and safer it is. The lever &
wedge arrangement are simpler and better, than any other arrangement I ever
saw.
And the rigidness of the clip, & drawbar arrangement are so improved over
any other system existing, for safely conducting a haulage round bends, curves,
or turns, without liability to mishap, that I claim it as the best means for the
work in the market.

Improvements in Haulage Clips and Drawbar Attachments for Rope
Haulage.
I WILSON GRAHAM 7 Bransty Villa Bransty Whitehaven Cumberland
Colliery Overman 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 has for its object improvements in haulage clips and draw bar
attachments for rope haulage by which means single tubs or trams and trains of
tubs or trams may be easily and safely moved from place to place on the rope
haulage system and by the labour of only one boy who can easily put it on and
take it off thus saving a considerable amount of labour in a simple and effective
manner. The arrangement is rigid in all parts and is particularly adapted for
safely conducting a haulage roun bends curves or turns without so much liability
to mishap while the greater the weight behind it the firmer and safer it remains.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto two sheets of drawings upon which I
have fully illustrated the nature of my said improvements together with a
modification.
Figure 1 is an elevation of one side of my clip and draw bar attachment.
Figure 2 is a view looking from the other side.
Figure 3 is a view of the draw bar and coupling detached.
Figure 4 is a side elevation shewing a modification with the double wedge.
Figure 5 is an elevation of the end of Figure 4.
Figure 6 is a section through the end of a tram shewing a suitable eye bolt for
use in connection with ordinary draw bars.
In carrying my invention into effect I form my attachment a in cast steel or iron
but by preference of mild steel the body of my clip being curved from the top at a¹
so as to throw the front part forward to project sufficiently in front of tram to
be conveniently worked. The clip is provided with double jaws a² at the top
above the curve the pin b being provided in centre by which means the clip is
attached to the draw bar. From the bottom of the jaws a² the clip a is curved
and slotted out at d the slot being shaped like a double triangle, the V points
facing each other, and in this slot the lever m or levers are attached by the pin e.
From the bottom of this slot d the body gradually thickens again and is again
curved forward and the gripper fis formed at the bottom of the clip a with a side
opening to enable the rope to be slipped in or out.

page_text: This gripper f may be either single as shewn on Sheet 1 or double as shewn on
Sheet 2 so as to admit of either single or double wedges k being used the gripper
being tapered inside to suit the wedge.
In case of a single wedge the butt of the wedge k goes into the gripper f from
the rear but in case of double wedges k and k¹ Figures 4 & 5 both wedge points
approach each other in the centre of the gripper one entering from the front and
the other from the rear simultaneously. I have described what represents the cast
or moulded part of my clip a and into this I insert the lever m into the slot d which
lever m is curved as shewn at m¹ and is fitted with a suitable wedge k or wedges k
and which are inserted in the gripper f & brought to bear upon the rope at will
by simply striking or raising the lever m as required.
In the case of a single wedge as shewn on Sheet 1 the one lever lifts or replaces
it in case of a double wedge being used the lever m does for both by means of the
arrangement of half moon toothed cogs n and n' which are arranged in the slot d
so that by the action of one lever m both wedges and k¹ are raised or lowe ed
into position simultaneously.
The wedges are tapered to suit the box and grooved on the under side to suit the
rope and are drawn firmly into position by the action of the rope when in motion.
The draw bars which is preferably constructed of mallable iron is provided
betwixt the coupling or crook t and body of tram and on to this clip is fixed by the
pin and thus held firmly and rigidly in position.
The draw bar s is attached to the tram with square necked bolts or suitable eye-
bolts w may be utilised and made to suit the jaws a² of the clip as shewn by Figure 6
thus saving the cost of altering the draw bars s at collieries and other places where
the plant is already down. In this figure is the eye for pin b and w is the square
necked bolt which passes through the draw bars and tram for securing the draw
bar in position while w¹ is a wedge shaped guiding projection.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is.
The improved haulage clip and draw bar attachınent either separately or com-
bined substantially as herein set forth and shewn upon the accompanying two
sheets of drawings.
Dated this 7th day of August 1895.
