A New or Improved Rope Clip or Grip for the Rope Haulage of
Coal Tubs, Corves, and other Vehicles Travelling on Colliery
and other Tramways.
I ROBERT SUMMERSIDE WILLIAMSON of Cannock and Rugeley Collieries,
Hednesford in the County of Stafford Mining Engineer do hereby declare the
nature of this invention to be as follows:-
My invention consists of a rope clip or grip for the rope haulage of coal tubs,
corves and other vehicles travelling on colliery and other tramways, the parts of
the said clip or grip being constructed arranged and acting substantially as herein-
after described.
My new or improved rope clip or grip consists essentially of three parts;
namely of a fixed upper jaw and a lower sliding jaw, together with a combined
screw box and winch handle for working the sliding or lower jaw. The two jaws
are extended on one side and in the opposed faces of the said extended parts
shallow depressions are made for receiving and gripping the haulage rope. The
clip is carried by a bracket on the coal tub or corve and the fixed jaw is provided
with an arm through an eye in the end of which a rod from the coal tub or vehicle
coupling passes. The lower sliding jaw carries at its middle a vertical stem, oblong
or square in cross section, and the said angular part of the stem is surmounted by a
screw. The angular stein of the sliding jaw works in a correspondingly shaped
hole or opening in the fixed jaw. On the screwed end of the stem of the lower
sliding jaw is a rotating screw box actuated by a winch handle made in one piece
with the screw box. The screw box takes a bearing against or seats itself on a
collar on the fixed jaw so that by rotating the winch handle in one or other
direction the screwed end of the stem rises or falls in the screw box and the movable
jaw is raised to or separated from the fixed jaw thereby gripping or releasing the
hauling rope travelling between the opposed faces of the two jaws. When the two
jaws are closed upon the hauling rope the tub or corve is connected to and made to
travel with the said rope and when the two jaws are separated so as to release the
hauling rope the tub or corve comes to rest as is well understood.
My new or improved rope clip or grip has the following advantages. It is very
simple in construction every part being easily accessible and in consequence of the
small number of working parts the clip is less liable to get out of order than
ordinary rope clips. The parts of the clip are very durable and efficient in action
and can be readily detached and repaired without skilled labour.

A New or Improved Rope Clip or Grip for the Rope Haulage of
Coal Tubs, Corves, and other Vehicles Travelling on Colliery
and other Tramways.
I ROBERT SUMMERSIDE WILLIAMSON of Cannock and Rugeley Collieries,
Hednesford in the County of Stafford, Mining Engineer do hereby declare the
nature of the said 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 consists of a rope clip or grip for the rope haulage of coal tubs,

page_text: corves and other vehicles travelling on colliery and other tramways the parts of
the said clip or grip being constructed arranged and acting substantially as herein-
after described.
My new or improved rope clip or grip consists essentially of three parts;
namely, of a fixed upper jaw and a lower sliding jaw together with a combined
screw box and winch handle for working the sliding or lower jaw. The two jaws
are extended on one side and in the opposed faces of the said extended parts,
shallow depressions are made for receiving and gripping the haulage rope. The
rope is connected to the coal tub or corve from the fixed jaw provided on the clip
by a rod or chain from the tub or vehicle coupling. The lower sliding jaw carries
at its middle a vertical stem oblong or square in cross section and the said angular
part of the stem is surmounted by a screw. The angular stem of the sliding jaw
works in a correspondingly shaped hole or opening in the fixed jaw. On the
screwed end of the stem of the lower sliding jaw is a rotating screw box actuated
by a winch handle made in one piece with the screw box. The screw box takes a
bearing against or seats itself on a collar on the fixed jaw so that by rotating the
winch handle in one or other direction the screwed end of the stem rises or falls in
the screw box and the movable jaw is raised to or separated from the fixed jaw
thereby gripping or releasing the hauling rope travelling between the opposed
faces of the two jaws. When the two jaws are closed upon the hauling rope the
tub or corve is connected to and made to travel with the said rope and when the
two jaws are separated so as to release the hauling rope the tub or corve comes to
rest as is well understood.
Figures 1 and 2 of the accompanying drawing represent elevations, taken at
right angles to one another, of a haulage rope clip or grip constructed according to
my invention;
Figure 3 represents a plan and cross section of the same, the sectional part being
taken on the line, a Figure 1 ;
Figure 4 represents in plan the upper side of the fixed jaw of the clip and
Figure 5 represents in plan and side elevation (partly in section) the combined
screw box and winch handle of the clip detached.
The same letters of reference indicate the same parts in the several figures of the
drawing.
a is the fixed upper jaw and 6 is the lower sliding jaw of the clip or grip; a² is
the side extension of the fixed jav a and b² is the side extension of the sliding jaw b.
In the opposed faces of the said side extended parts a², 62 of the two jaws shallow
depressions or concavities are made for receiving and gripping the travelling
haulage rope (see Figure 2). On the side of the fixed jaw a is an arm a through
the eye a¹ in the end of which a rod from the coal tub or corve coupling passes.
The method of fixing my improved clip to the coal tub, corve or vehicle is in all
essential respects the same as that by which ordinary rope haulage clips are fixed to
the tubs, corves or vehicles and I therefore do not think it necessary to describe in
detail the said method of fixing. The lower jaw b carries at its middle a vertical
stem c, oblong (or square) in cross section (see Figure 3) and the said angular
stem c is surmounted by the screw d. The angular stem c of the lower jaw b works
in a correspondingly shaped hole or opening af in the fixed jaw a, so that while the
said stem c is capable of sliding in the fixed jaw a it is incapable of a rotary motion
therein; e is the screw box carried by and made preferably in one piece with the
winch handle by which the screw box is rotated. The combined screw box and
winch handle e, is represented detached from the clip in Figure 5. When the
screw box e is fitted in its place it works upon the screwed part of the stem of the
lower sliding jaw.
The screw box e is fitted to the fixed jaw a of the clip in the following manner.
The underside of the screw box e is furnished with a collar g which works against
an undercut shoulder / made at the top of the fixed jaw a with which shoulder the
collar g is engaged by a lateral sliding motion (see Figure 1). In order that the
collar g of the screw box may be engaged with the undercut shoulder one half of

page_text: the top of the fixed jaw a is cut away at a as best seen in Figures 2 and 4. To
connect the combined screw box and winch handle to the upper fixed jaw a (the
lower sliding jaw being detached) the collarg is placed upon the seat formed by the
cut away part as of the said fixed jaw and opposite the undercut shoulder h. By
giving the screw box a sliding lateral motion, half of its collar
9 engages with the
undercut shoulder 1 and half rests on the seat or cut away part a and the combined
screw box and winch handle e, f is connected with the clip. By then introducing
the screw stem c, d of the lower jaw into the fixed upper jaw a and rotating the
screw box e by its winch handle the screwed part d of the lower jaw is drawn.
into the screw box e as represented in the drawing. The clip is now ready for use,
and the combined screw box and winch handle cannot be removed from the clip so
long as the screwed end d of the lower sliding jaw b is engaged with the screw
box e.
By rotating the screw box e in one or other direction by its handle f the
collar g on the said screw box works against the undercut shoulder h and bears on
the seat or cut away part at a, and the screwed stem d rises or falls in the said
screw box e and the movable jaw b is raised to or separated from the fixed jaw a,
thereby gripping or releasing the hauling rope travelling between the opposed faces.
of the lateral extensions a², 62 of the said jaws. When the parts a², 62 of the jaws
are closed upon the travelling rope the tub, corve or vehicle is connected to and
made to travel with the said rope and when the said jaws are separated the
travelling hauling rope is released and the tub corve or vehicle comes to rest.
My new or improved rope clip or grip has the following advantages. It
simple in construction every part being easily and quickly detachable, and in
consequence of the small number of working parts the clip is less liable to get out
of order than ordinary rope clips. The parts of the clip are very durable and
efficient in action and can be readily detached and repaired without skilled
labour.
very
Having now particularly described and ascertained the nature of my inven
tion and the manner in which the same is to be performed I declare that I claim as
my invention
The new or improved rope clip or grip for the rope haulage of coal tubs, corves
and other vehicles travelling on colliery and other tramways herein before described
and illustrated in the accompanying drawing; that is to say, a rope haulage clip or
grip consisting essentially of a fixed upper jaw and a lower sliding jaw having an
angular stem screwed at its upper part, working in the fixed jaw in conjunction with
a combined screw box and winch handle for working the said sliding lower jaw, the
two jaws being extended on one side and having in their opposed extended faces
shallow depressions or concavities for receiving and gripping the travelling haulage
rope working between them the several parts being constructed arranged and acting
substantially as described and illustrated.
