PROVISIONAL SPECIFICATION.
A New or Improved Gripping Device for the Conveyance of Objects
in Cable Haulage.
I, JAMES EDWARD WALTON of the Midland Bank, Wednesbury in the County
of Stafford Bank Manager, do hereby declare the nature of my said invention to
be as follows:-
My invention has for its object a new or improved gripping device for the
conveyance of objects in cable haulage which by its simplicity reduces the time
necessary for attaching and detaching the grip to and from the cable and is.
generally more economical in its construction and use.
The main body of my new gripping device is composed of a casting or forging
having a bottom jaw which lies under the cable with an upper box like construc-
tion terminating at the top with two snugs or a jaw in which a lever is hung.
Inside the box suitable slides are provided in which the movable top jaw slides up
and down and this jaw is held in its open position by means of a spring or springs.
On the top of the moving jaw an adjustable pin to suit various sized ropes is set
the pin being locked in position by a lock nut let into the body of the jaw through
an opening in the front of the jaw or a dovetailed or other wedge or renewable
piece may take the place of the pin. The point of the before mentioned lever is
formed into an eccentric nose which bears upon the pin or other bearing and
forces the movable jaw down upon the rope by one action of the hand and wheni
the lever is lifted the jaw automatically returns upwards by the action of the
spring or springs or as an equivalent links or a joggle joint action may be attached
to the lever and jaw to effect the same purpose. The lever may if necessary be
held down by a cottar key or wedge or link and chain or thumb screw from the
side of the box or by a weighted lever spring catch or a second arm clip or the
lever may be notched for the use of a peg through holes in a projecting portion of.
the box or a supplemental locking cam may be used.

A New or Improved Gripping Device for the Conveyance of Objects
in Cable Haulage:
I, JAMES EDWARD WALTON of The London and Midland Bank Ltd.,
Wednesbury, in the County of Stafford Bank Manager, do hereby declare the
nature of my 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 has for its object a new or improved gripping device for the
conveyance of objects in cable haulage which by its simplicity reduces the time
necessary for attaching and detaching the grip to and from the cable and is
generally more economical in its construction and use.

page_text: The main body of my new gripping device is composed of a casting or forging
having a bottom jaw which lies under the cable with an upper box like construc-
tion terminating at the top with two snugs or a jaw in which a lever is hung.
Inside the box suitable slides are provided in which the movable top jaw slides up and
down and this jaw is held in its open position by means of a spring or springs. On
the top of the moving jaw an adjustable pin to suit various sized ropes is set, the
pin being locked in position by a lock nut let into the body of the jaw through
an opening in the front of the jaw or a dovetailed or other wedge or renewable
piece may take the place of the pin. The point of the beforementioned lever is
formed into an eccentric nose which bears upon the pin or other bearing and forces
the movable jaw down upon the rope by one action of the hand and when the lever
is lifted the jaw automatically returns upwards by the action of the spring or
springs or as an equivalent links or a joggle joint action may be attached to the
lever and jaw to effect the same purpose. The lever may if necessary be held.
down by a cottar, key or wedge or link and chain or thumb screw from the side of
the box or by a weighted lever, spring catch or a second arm and clip or the lever
may be notched for the use of a peg through holes in a projecting portion of
the box or a supplemental locking cam may be used.
In order that my invention may be clearly understood and more easily carried
into effect I have appended hereunto two double sized sheets of drawings upon
which have illustrated an example of my invention, but it will be clearly
understood that the designs or configurations of the various parts may be changed
without departing from the essence of the invention.
Figure 1 is a longitudinal vertical part section and part elevation of my gripping.
device showing the lever L in its upper position as well as the box B lifted and
the jaw open for the rope R to enter.
Figure 2 is a similar longitudinal part section and part elevation to Figure 1
but with the lever down and the inner box B gripping the rope R.
Figure 3 is a cross section and part elevation with the lever L in its upper
position and the jaws open.
Figure 4 is an end elevation of the gripper when the lever is down and the
inner box B is in its closed position.
Figure 5 is a side elevation of the gripper with the lever closed down with the
inner jaw or box.B fast upon the rope R.
:
The skeleton, frame or outer box A of my gripper is cast from steel or made
hollow to receive the inner or sliding box B which is free to move upwards as
operated by the springs S and downwards as operated by the lever L but the
inward flange a would apart from the spring and anvil E prevent the box
travelling too high if that were needed but this flange also strengthens the top
opening of the box. The box A is greatly thickened and strengthened on one side
from which the lower jaw of the gripper projects turning and projecting under the
inner box B and finishing inside the projection a' at a with a hollow to receive the
underside of the rope R. The outer box or frame A may have the snugs or
provision a¹ and hole a³ at one or both ends and also the upper snugs as and a which
form a jaw to receive the thickened portion of the lever L and in which the lever
is secured by the pivot pin a.which may be a bolt or other contrivance so long as
it is sufficiently strong. to bear the whole strain upon the grip which it is required
to do. The inner box or grip block B is provided with the hole 6' to receive the
anvil E which has a rounded corner e¹ and this anvil block may be packed up to
suit any rope or to make up for wear by various thicknessed packing pieces P.
which may be exchanged at any time. A hole is provided in the block B at.
each end to receive the springs S which are secured by the pins at the bottom
to B and at the top to A by similar pins a. These springs are in tension and
therefore always tend to bring the inner block or box B to the upper or open
position as seen at Figures 1 and 3.
.
The lever L is formed and mounted between the snugs a' and a of A as before
explained and the nose of the lever is formed with its flat portion against

page_text: which the top of the anvil E bears when the gripper is open as seen at Figures 1.
and 3.
Immediately the lever is pulled over, the rounded nose of the lever L bears.
upon the rounded corner e¹ of the anvil E bringing the inner block or grip B down
upon or near to the rope R. The formation of the nose of the lever from to -
and is an irregular curve increasing in its distance from the centre a very
gradually to the point which is upon the anvil E as seen at Figure 2 when the
rope R is locked the grip at the point being very powerful and effective which is.
due to the particular formation of the nose of the lever and the general construc-
tion. The lever may be locked in this position by a ratchet arrangement or by
links with a pin or in any other convenient manner.
Immediately the lever is turned back the inner block or jaw follows close upon
it which is due to the action of the springs S and the formation and mounting
which gives steadiness and certainty in action. The lever may be turned end for
end and the anvil block E also. The anvil block E may of course be solid with B.
but I prefer to have it loose for the convenience of renewals and for adjustability..
The anvil is secured in position by the set screw 6*.
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 :-
The new or improved gripper for wire rope haulage consisting of the outer box
or casing A and the inner box or sliding block B with its anvil E operated by
the lever L with its special nose substantially as herein set forth and shown upon.
the accompanying drawings by Figures 1 to 5 inclusive.
