Improvements in Gripping Appliances for Ropes, Cables, Rods,
and other like purposes.
I, DAVID THOMAS YOUNG, a member of the Firm of "Youngs" Ryland Street
Works, in the City of Birmingham, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the manner in which I construct and arrange gripping
jaws or clips for the purpose of securing in position varying sizes of ropes, wire
cables, tubes, rods and for other like purposes, whereby I am enabled to utilize one
or more pairs of jaws or clips for securing large or small articles with the same
appliances or clips.
In carrying my invention into effect when applying my improved jaws or clips to
a rigging screw,
arrange the guides or side arms upon which the clips bear in the
usual manner, and employ the ordinary screw passing through an end nut or head.
for the purpose of causing one fixed or loose jaw crosshead to travel up and down
on the guide bars. The jaw or clips I make with a V shaped configuration when
it is desired to secure a round article and I arrange them in pairs the one above the
other, but the bottom or under clip I form with a slot or slots within it so that the
upper jaw may pass any required distance or right through the lower one, thus
by the embracing or passage of the one jaw through the other varying sizes
of rods, tubes, ropes, cables, wires or other materials can be gripped between the
embracing surfaces.
Instead of making the jaws with V shaped nipping surfaces I sometimes make
them circular or of curved or other configuration to suit any special requirement for
holding in position any desired shape of article.
I apply my sliding jaws to vices constructed in the ordinary way so far as
regards their general shape and principle of working, the jaw portion alone being
made to enter one piece within the other for the purpose of nipping a small or large
rod, rope or bar as may be required. These gripping appliances may form
an integral part of the article or be fitted to the saine separately. Similarly I
arrange my special reducing or folding jaws to ordinary wire rope stoppers
where it is desired to hold in position different sizes of rope by the one appliance.
When arranging my improved jaws for appliances where two or three cables
have to pass through the one frame I make the jaws with a like number of
openings so that any desired number of pieces may be secured by the folding
or embracing clips, or 1 make the required number of jaws with one or more
openings on each. A range of jaws may be in one or more parts and may be
arranged to work together or independently of each other.
I modify the shape and arrangement of my jaws to suit any particular purpose,
and I do not limit the application of my invention to any particular form of rigging
screw, vice, clipping bench, or other article to which this invention may be applied,
but I employ the same essential features of an embracing clip, the aperture of
which can be enlarged or reduced to suit any particular requirement and I arrange
my jaws to work vertically, horizontally or at any desired angle.

1, DAVID THOMAS YOUNG, a member of the Firm of "Youngs," Ryland Street
Works, in the City of Birmingham, 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 :-
This invention relates to the manner in which I construct and arrange gripping
jaws or clips for the purpose of securing in position varying sizes of ropes, wire
cables, tubes, rods and for other like purposes, whereby I am enabled to utilize one
or more pairs of jaws or clips for securing large or small articles with the same
appliances or clips.
In order that my invention and the method of carrying the same into effect may
be the more readily understood, I append hereunto five sheets of explanatory
drawings to be hereinafter referred to.
Sheet shows the application of my invention to a rigging screw having a
rectangular jaw or aperture, Figure 1 being an elevation, Figure 2 an end view
showing the end jaw in Figure 1, and Figure 3 a similar view showing the
other jaw.
Sheet 2 represents a similar application to a rigging screw having curved or
circular jaws or apertures.
Sheet 3 illustrates a riggers' vice in combination with my improved gripping
jaw, Figure 7 being an elevation, Figure 8 a plan and Figure 9 a section on line x y
Figure 7.
Sheet 4 shows the application of my improved jaws for appliances where two
cables have to pass through one frame, Figure 10 being a front, and Figure 11 an
end elevation, Figure 10 being also a part section showing connection of screw to
movable jaw.
Sheet 5 represents two general forms of haulage clips constructed in accordance
with my invention, Figures 12, 13 and 14 being elevation, plan, and sectional views
respectively of a clip having a swivelling eye pin, while Figures 15, 16 and 17
are similar views of a clip having an eye formed in connection with the tightening
screw.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect when applying my improved jaws or clips to
a rigging screw such as illustrated on Sheet 1, I arrange the guides or side
arms A A' upon which the clips bear in the usual manner, and I employ the
ordinary screw such as B, passing through an end nut or head C, for the purpose of
causing one fixed or loose jaw crosshead to travel up and down on the guide bars.
The jaws or clips D D' I make with a V shaped configuration when it is desired to
secure principally a round article, and I arrange them in parts, the one above the
other, but the bottom or under clip or the upper jaw D as shown in Figures 1 and 2
I form with a slot such as d Figure or slots within it so that the upper V jaw or
the lower jaw D of Figure 1 may pass any required distance or right through the
opposite one, thus by the embracing or passage of the one jaw through the other
varying sizes of rods, tubes, ropes, cables, wires or other materials can be gripped
between the embracing surfaces.
Instead of making the jaws with V shaped nipping surfaces as shown on
Sheet 1 sometimes make them circular or of curved configuration as shown on
Sheet 2 or other configuration to suit any special requirement for holding in
position any desired shape of article.

page_text: I apply my sliding jaws to riggers' or other vices constructed in the ordinary
way so far as regards their general shape and principle of working, the jaw
portion alone being made to enter one piece within the other for the purpose of
nipping a small or large rod, rope, or bar, as may be required, as illustrated by
the three views on Sheet 3. These gripping appliances may form an integral part
of the article or be fitted to the same separately. Similarly I arrange my special
reducing or folding jaws to ordinary wire rope stoppers where it is desired to hold
in position different sizes of rope by the one appliance.
When arranging my improved jaws for appliances where two or three cables
have to pass through the one frame I make the jaws with a like number of
openings so that any desired number of pieces may be secured by the folding or
embracing clips, or I make the required number of jaws with one or more openings
on each. A range of jaws may be in one or more parts and may be arranged to
work together or independently of each other.
Figures 10 and 11 Sheet 4 represent one form of frame that I employ
having a double jaw for gripping two ropes, cables or other articles. Such an
appliance arranged for one or any required number of ropes or cables is employed
for the purpose of nipping or gripping a rope or cable, in order that it may be put
under a degree of tension during winding sufficient to enable it to be properly
wound or coiled upon a barrel or drum. The appliance is also applicable for
general rope, cable, or other gripping purposes. The two or more jaws may be
opened or closed by the movement of one operating screw with which they are
connected preferably in the manner shown at Figures 10 and 11.
I employ a modification of the frame illustrated on Sheet 4 to form a gripper
for attachment to the cars of a cable tramway and for such purpose I preferably
make the upper jaw a fixture and impart a sliding or gripping motion to the lower
jaw by means of a screw or a suitable system of leverage. The lower jaw is
arranged to enter into or to be embraced by the upper or fixed jaw.
The haulage or other clip or gripper as shown at Figures 12, 13 and 14 has a
swivelling eye pin E, which passes through a plain hole formed in the screw
plug F, and enters at the extremity of its shank end, which is reduced in diameter,
into the upper part of the upper or top jaw.
The connection is so made that the pin shall have no end movement, and yet be
free to turn or revolve. The lower or bottom jaw is preferably formed with the
body G of the clip. The head of the screw plug F I form hexagonally or of some
other shape that may be embraced and operated by a spanner. The tightening
or slackening of the screw causes the rope, cable, chain, or other haulage con-
nection, to be gripped or released, provision being made to allow the upper jaw
to enter within and pass through the lower jaw so that a secure grip may be
obtained.
The clip illustrated by Figures 15, 16 and 17 has the screw thread formed or
cut upon the eye pin. The connection of the screwed eye pin to the upper jaw I
preferably make in the same manner as the connection of the swivelling pin
hereinbefore described. In either type of clip the form of the eye pin and other
parts are modified to suit varying requirements.
Instead of producing the sliding movement of one jaw necessary for the gripping
action, by means of a screw plug working in a nut or thread formed in the body of
the clip as herein before described, I sometimes produce the sliding movement by
means of toggle or other levers, or by a combination of both screw and lever as
may be the more convenient.
I modify the shape and arrangement of my jaws to suit any particular purpose,
and I do not limit the application of my invention to any particular form of rigging
screw, clipping frame, or other article to which this invention may be applied, but
I employ the same essential features of an embracing clip, the aperture of which
can be enlarged or reduced to suit any particular requirement and I arrange my
jaws to work vertically, horizontally or at any desired angle.

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, declare that what I
claim is :-
--
1. A rigging screw or other like appliance having nipping or gripping jaws
entering the one within the other substantially as herein before described and as
illustrated in the accompanying drawings.
2. The construction of a rigging screw, having a shaped jaw such as D with a
