A Binder for Attaching Telegraph and other Aërial Lines to their

WILLIAM WALTER GERALD WEBB 9 Coppenhall Terrace Crewe Mechanical
Engineer, AUGUSTUS ECKSTEIN 45 Chapel Street Salford Manchester Electrical
Engineer do hereby declare the nature of this invention to be as follows:-
Our invention consists in a form of binder whereby overhead wires may be
readily and efficiently attached to their insulators in such a manner that a con-

siderable saving of time over the usual methods of fixing is effected.
our invention into practice by taking a horse-shoe shaped clip of steel or other
material of a sufficient strength for the purpose, whose curved portion approximates
to the curve of the groove in insulator; the extreme ends of this clip being formed
into curved hooks of suitable size to hook on to the line wire.
A cam lever, preferably stamped out of steel, having a hole at its centre of
oscillation, is passed onto the clip so as to occupy a position midway between the
two arms of the clip. The size of the clip is such that when the line wire is
stretched and then placed tangentially in the groove of the insulator, the clip can
be hooked on
to the line, & just slipped into its place in the groove of the
insulator, the smaller radius of the cam being next to the insulator.
In order to secure the line to the insulator, the arm of the cam lever is moved,
so as to gradually bring the longer radius of the cam next to the insulator,
whereby a force is brought to bear upon the clip & the wire by the action of the
cam, and causing the wire to bend to the curve of the insulator between the arms
of the clip and so to firmly lock the wire, clip & insulator together.
When it is necessary to remove the wire, it is evident, that by bringing the cam
back to its first position, the clip may be easily unhooked. Instead of the cam
being allowed to bear upon the ordinary surface of an insulator, we sometimes
prefer to form in the insulator an indentation or groove conforming to the curve
of the cam, which serves as a guide for the cam, & also tends to increase the
locking power when the cam is pulled over.

We, WILLIAM Walter Gerald WEBB, of No. 9 Coppenhall Terrace Crewe,
in the County of Chester, Mechanical Engineer, and AUGUSTUS ECKSTEIN
of 45 Chapel Street Salford Manchester in the County of Lancaster Electrical
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 :-
The object of our invention is the construction of a binder, by the employment

page_text: of which overhead wires may be readily and efficiently attached to their insulators
in such a manner that a considerable saving of time over the usual methods of
fixing is effected without diminishing the security thereof.
In order that our invention may be the better understood we have appended the
accompanying sheet of drawings in which
Figure 1 is a sectional plan view, and Figure 2 an elevation of the device showing
the arrangement and method of application.
Figures 3 and 4 are respectively plan and elevational views of a modification
also showing the adaptation to a different type of insulator.
Similar reference letters are used in all the views.

In carrying our invention into practice we construct a horse shoe shaped clip A,
of steel or other material of sufficient strength for the purpose. The curved
portion approximates to the groove g in the insulator I, the extreme ends of said
clip being formed into curved hooks of suitable size to hook on to the line
wire W. A cam lever c with a lug or handle d, preferably stamped out of steel
plate, having a hole at its centre of oscillation is passed over the clip A as shown,
occupying a position midway between the two arms thereof. The size of the
clip A is so arranged that when the line wire W is stretched and then placed
tangentially in the groove g of the insulator I, the clip A may be hooked on the
wire W by the hooked ends h, the minor radius of the cam c being then next to the
insulator I. Now, in order to secure the line W to the insulator I the arm d of
the cam c is moved so as to gradually bring the major radius of the cam c next to
the insulator I whereby a force is brought to bear upon the clip A and the wire W
by the action of said cam e causing the wire W to be bent into the groove g and so
firmly lock the wire W, clip A and insulator I together.
When it is necessary to remove the wire W it is evident that by bringing the
came back to its first position the clip A. may easily unhooked and the wire W
released. Instead of allowing the cam c to bear upon the ordinary surface of the
insulator I we may in some instances form in said insulator a groove or indentation
conforming to the curve of the cam c, or, as in the case illustrated by Figures 3
and 4, a projection i upon said cam c is forced into the groove 9, and in both
instances the locking power is increased when the cam is pulled over.
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 ;-
First. The binder for attaching telegraph or other aërial wires to their insulators
and the combination of parts forming the same substantially as described in the
Specification and shown by the drawings.
.
Second. In binder for attaching telegraph and other aërial wires to their
insulators the combination of a cam c with or without a projection i, and insulator I,
clip A and line wire W substantially as herein described and shown by the
drawings.
Third. In a binder for attaching telegraph and other aërial wires to their
insulators the manner of operating, fixing, and adjusting the several parts to fulfil
the object thereof, substantially as herein set forth, with reference to the appended
drawings.
