PROVISIONAL SPECIFICATION.
Improved Combined Automatic Cable Grip and Fairleader for Ships
and other purposes.
We JAMES DAVISON, of 10, Hyde Street, Hendon, Sunderland, Engineer, and
JOHN DAVISON, of 21 Ryhope Street, Ryhope, Hotel Keeper, both in the County
of Durham, do hereby declare the nature of this invention to be as follows:-
This invention relates to means of securing or gripping wire ropes, cables and
the like automatically by means of eccentric levers which are secured to a central
casting by means of a shaft or pin which passes through the levers at a point to
give an eccentric motion when pressed down by hand, or forced down by means of
a coiled spring, which may be fitted to shaft and levers respectively. There is a
shoe of cast iron or steel connected to the levers by means of a jointed link which
is placed on a pin in the center of the radius, so that a greater gripping surface is
secured.
The invention allows of the rope or cable coming in freely, but will not allow
to run out unless the lever be lifted.
The grip being practically automatic in its action. The bottom of the shoes
and the top of the bedplate are grooved and rifled to ensure the desired friction
for drawing down the levers.
Guides or fairleaders are formed at each end of the main casting to keep the
cable in the grooves, and may be fitted with runners to destroy friction while
drawing in with the winch. Modifications of the invention may be made without
the shoes, the bed plate being radiused to fit the eccentric levers, the levers are
then grooved to grip the cables.
They may be adapted to either chains, wire, hemp or other ropes and cables.
They may be made double or single as may be required.

COMPLETE SPECIFICATION.
Improved Combined Automatic Cable Grip and Fairleader for Ships
and other purposes.
We, JAMES DAVISON, of 10 Hyde Street, Hendon, Sunderland, Engineer, and
JOHN DAVISON, of 21 Ryhope Street, Ryhope, Hotel Keeper, both in the County
of Durbam, 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 :-
Our invention relates to an improved combined automatic cable grip and fair-
leader for ships and other purposes.
And in order that our invention may be thoroughly understood, we now proceed
to describe the accompanying drawings thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a side elevation of the cable grip without a coil spring.
Fig. 2, is a plan of the top of the cable grip with and without a coil spring.

page_text: Fig. 3, is a side elevation of the cable grip with a coil spring.
Fig. 4, is a side elevation of the cable grip with a buffer spring and rod working
through the central piece.
This invention has for its object a means of securing or gripping wire ropes a
cables and the like automatically by means of eccentric levers 6 which are secured
to a casting or bedplate c which is made with a vertical central piece d reaching
up the desired height by means of a shaft e which passes through the levers bat
a point to give an eccentric motion or throw when pressed down by hand or drawn
down by means of a coiled spring fas in Fig. 3, or the like which may be
fitted to the shaft e and lever b respectively as shown in Figs. 2, and 3.
There may be a shoe g of cast iron or steel as in Fig. 3, connected to the lever b
by means of a jointed link h attached to a pin i or to studs placed in the centre
of the radius of the eccentric, so as to procure a longer gripping surface on the
cable or rope or the like. The jointed link works loosely on a curved bar k fixed
on each side of the shoe 9.
This invention by means of the eccentric motion or throw allows the cable or
rope a to be hauled in by hand or by any other power, but on being released
from a winch or hand the levers instantly close down upon it and the friction thus
obtained secures the cable at once; and if required to let go, or slack away, the
lever must be lifted by hand or otherwise before the rope or cable can be released,
by this means the grip is practically automatic and thereby securing greater safety
from accidents of all kinds.
The top of the bedplate e may be grooved slightly, and the bottom of the
shoe g may also be grooved and rifled to protect the cable or ropes from injury
and to ensure the desired friction for drawing down the levers, guide brackets or
webs are formed at each end of the casting and are provided with anti friction
runners or sheaves in any suitable shape or form to protect ropes or cables from
injury, and to guide the rope or cable along the proper groove or channel and to
keep the rope or cable from flying out. Clasps of iron or metal may be fitted as
may be required and of suitable shape to suit any size rope cable or chain.
They are adapted to chains, wire, hemp or any other ropes and cables, and may
be made with one or more levers, with or without shoes, with or without springs,
and may be fitted to suitable turntables or swivel plates or the like to suit various
and sundry other purposes other than for ships.
In Fig. 4, we provide a small runner which is fitted at each end corner of the
eccentric levers to resist the friction when heaving in rope.
The centre or main part d is separate from the base-plate c in which it slides.
A bar or shaft o passes through the centre of the main part d and on which a
spring p and a boss or fore ends is fitted, the said bar or shaft being bolted to
and supported by suitable brackets q attached to the base-plate c.
The spring p
is secured to the shaft o by a rivet o'. A spring may be fitted between the
bracket and the fore ends of the central piece or main part, or a cushion of
india rubber may be used instead of a steel spring.
The object of the bar or shaft o which passes through the middle of the
standard or main casting is simply to keep the spring p in position; the said bar
or shaft o being held in its place by the two brackets q one at each end of the
base plate c, the bar or shaft passes freely through the casting and being hollow
permits the spring to be fitted inside the casting. The object of the springs is to
take off the sudden jar when checking the ship or when the ship is veering about
in strong currents.
A perforated quadrant m may be fixed to the vertical central piece as in
Figs. 1, and 2, for fixing the haudle in any position by means of a pin n.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
―:
1. In an improved combined automatic cable grip and fairleader for ships and

page_text: other purposes, the combination of the eccentric lever or levers 6 mounted on a
shafte attached to a vertical central piece d on a bed-plate c sheaves with the

and 2, of the accompanying drawing.
2. In an improved combined automatic cable grip and fairleader for ships and
other purposes, the combination of the bed-plate c shoe g curved bars k jointed

4. In an improved combined automatic cable grip and fairleader for ships and
other purposes, the combination of the different parts hereinbefore described and.
illustrated for the various purposes specified.
5. In an improved combined automatic cable grip and fairleader for ships and
other purposes, the combination of the bed-plate c the sliding central piece d
