as
I, THOMAS ARCHER, of 6 Park Terrace, Gateshead on Tyne in the County of
Durham Engineer do hereby declare the nature of this invention to be
follows:-
My invention has for its object to provide a simple and efficient device by means
of which hauling ropes can be readily attached to and detached from the article
with which they are used my invention being more especially intended for use for
attaching hauling ropes to coal tubs used in collieries.
The device according to my invention consists of horns or projections set in
advance the one of the other in the line of draught and approaching each other
transversely to the line of draught and from above downwards so that when the
rope is placed between them it becomes wedged in position.
The device is provided with means whereby it can be attached to the article or
tub to be hauled and the rope is very simply attached by placing it between the
horns or projections when it descends and becomes wedged between the horns or
projections sufficiently to become fixed to the hauling device for hauling purposes
and it can be readily detached by an upward movement of the rope to release it
from between the horns or projections. The said horns or projections may be of
any suitable shape, placed in any suitable position and in any suitable number but I
prefer to use three horns or projections one on one side and two on the other and
each with an edge or angle at the part with which the rope comes in contact.

COMPLETE SPECIFICATION.
Improved Device for Attaching and Detaching Hauling Ropes or
the like, more especially intended for use for Attaching Ropes
to Coal Tubs.
I THOMAS ARCHER, of 6 Park Terrace, Gateshead-on-Tyne, in the County of
Durham, 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 :—
My invention has for its object to provide a simple and efficient device by means
of which hauling ropes can be readily attached to and detached from the article
with which they are used my invention being more especially intended for use for
attaching hauling ropes to coal tubs used in collieries.
The device according to my invention consists of horns or projections set in
advance the one of the other in the line of draught and approaching each other
transversely to the line of draught and from above downwards so that when the
rope placed between them it becomes wedged in position. The device is provided
with means whereby it can be attached to the article or tub to be hauled and the
rope very simply attached by placing it between the horns or projections when it
descends and become wedged between the horns or projections sufficiently to
become fixed to the hauling device for hauling purposes and it can be readily
detached by an upward movement of the rope to release it from between the horns
or projections. The said horns or projections may be of any suitable shape placed

page_text: in any suitable position and in any suitable number but I prefer to use three horns
or projections one on one side and two on the other and each may be provided with
an edge or angle at the part with which. the rope comes in contact.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the
several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figures 1 and 2 are elevations at right angles to cach other and Figure 3'a plan
of a device constructed according to my invention with three fixed horns.
Figure 4 is a plan of a similar device but with two of the horns connected
together so as to form a crescent the ends of the crescent-constituting bearing points
for the rope.
Figures 5 and 6 are respectively an elevation and a plan of a device having two
fixed horns and a moveable horn.
Figure 6 is a device having two fixed horns and two moveable horns and
Figures 7 and 8 are respectively an elevation and a plan of a device having four
fixed horns between any three of which the hauling rope may be gripped.
In the arrangement illustrated by Figures 1, 2 and 3 the projections or
horns AA and A2 are formed on a base B the horns A A being arranged in line
one with the other in the direction of the line of draught whilst the horn A² is
situated about midway between the horns A but not in line therewith. The upper
ends of these horns are bent or curved outwards transversely to the line of draught
as shewn at a in Figure 2 to facilitate the introduction of the rope C and are
inclined inwards and downwards towards the base B so as to form a tapered or
wedge shaped recess b for the rope C as also shewn in Figure 2 so that when the
rope is placed therein it becomes wedged in position. The device may be fixed to
the coal tub or the like in any suitable manner and may be provided with a spring
or springs so as to yield to sudden jerks and so prevent the rope or the gripping
device from being damaged thereby. In Figure 1 and in Figures 7 and 8 the
device is shewn as being provided with means for fixing it to the side E of a. coal
tub the said means consisting of a square socket D on the tub to receive a square
part on a stem or leg D2 depending from the under side of the base B and the
lower end of this stem or leg may if desired enter a strap or socket F attached to
the side E. In the modified construction illustrated by Figure 4 instead of the two
horns being separate they are connected together so as to form a curved projection
between the ends A A of which projection and the intermediate horn A² the rope C
is securely held. Instead of forming the three horns or projections A and A on
the base B as shewn in Figures 1, 2 and 3 the horn A² may be formed on a
piece B2 as shewn in Figures 5 and 6 the piece or arm B2 being pivotted to the
base B at a point e midway between the horns or projections A 'but at the opposite
side thereof in a direction transversely to the line of draught to that where the
horn A is situated. By this arrangement when the rope C is placed between the
horns and a strain is on the rope the said rope will tend to move the horn A
towards the fixed horn. A in the direction of the strain and thereby increase the
grip on the rope. I may provide the arm'B' with two horns arranged one on each
side of the horns A A. in a direction transverse to the line of draught or as
illustrated by Figure 6 the two moveable horns A2 A³ may each be carried on a
separate arm B2 B3 pivoted to the base B one above the other on one pivote. By
providing four horns as described the hauling rope may be gripped between the
horns A A and either the horns A² or A3. as most convenient. In the modification
shewn in Figures 7 and 8 there are four horns formed on the base B the said horns
being arranged one at each corner of a square the diagonal of the square being in
the direction of the line of draught. By this arrangement the apparatus may be
fitted to the coal tub or the like with either two diagonal horns in the line of
draught and when the horns become worn by the rope on one of their sides the
device may be turned a quarter round so as to bring another of their sides into
position to grip the rope.

page_text: 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 :-
For connecting coal tubs or the like to hauling ropes a device consisting of three
or more horns or projections arranged in advance one of another in the direction of
the line of draught one or more of the said horns or projections being arranged at a
distance from the others in a direction transverse to the line of draught and made
to incline towards each other from above downwards in a direction transverse to
the line of draught substantially as hereinbefore described and illustrated in the
accompanying drawings.
