Improvements in Hinges or Joints for Electrical Purposes.
1, GEORGE WILLIAM GOLDRING of 24 Terminus Road, Brighton Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention refers to flexible or movable joints hinges or other connections,
for electrical instruments or machines, such as dynamos, switches, meters, and the
like, and consists in forming at each joint two knuckles one on each of the ends to
be coupled each knuckle composed of two projecting lugs or ears connected by a
rod or bar preferably round said bar having one or two links or connecting pieces
working freely either upou or around the bars themselves between the two lugs or
upon pins or screws attached on the outside of the lugs and in the centre of the
diameter of the said bars the said links allowing the bars to keep parallel to one
another and work freely.
When the knuckles are connected by the links aforesaid, the bars will lie parallel
to and a short distance froin each other.
They are formed by preference of brass gunmetal or copper.
I connect the said bars by means of a movable or flexible ligature composed of a
braid or strand of fine copper wires twisted, woven or plaited together, and arranged
around the bars by preference in the form of an S or figure 8. These wires may
be first formed into cord or strand and then interlaced but always so as to allow
the said bars and knuckles to move freely when required. The ends of said wires
can be fastened by soldering to the bars or in any other suitable way.
Instead of the outside links I sometimes bring the ends of the knuckles together
so that their faces being suitably rounded they engage together with a rolling
motion at the points of contact.
The copper braid or strand forms in this case the connection between the 'two
bars and holds the knuckles together.

I, GEORGE WILLIAM GOLDRING of 24, Terminus Road, Brighton 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 refers to flexible or moveable joints and hinges for electrical
instruments or machines, such as meters, switches, dynamos and the like, and
consists in forming at each joint two knuckles one on each of the ends to be
coupled, each knuckle composed of two or more projecting lugs or ears connected
by a rod, bar or tube preferably round as shown in Diagram I, or, the said bar
may be divided so that each knuckle shall be formed of two separate lugs each

page_text: Fig. 12 shows a plan of a joint constructed without side links a. The knuckles
are rounded and are in contact, and the joint is held together by the ligature k.
Fig. 13 shows an end view of Fig. 12.
Fig. 14 shows a method of attaching the ligatures in short lengths, the ends 4
being soldered to the bar or tube.
Fig. 15 shows the ligature used as an endless cord, in the shape of a figure
eight (8).
a, a, are the side links connecting the knuckles b, b; c, c, are the parallel bars or
tubes around which the ligature wound; d, d, are clamping 'screws for securing 5
the ends of the ligatures; k is a ligature in the form of a cord or strand and k¹ is
the same in the form of a braid..

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 I declare that what I
claim is,
1. In a hinge joint for electrical purposes the woven flexible cord or braid,.
formed of fine wires used in the form of the letter or figure S or 8, as herein.
described and set forth.
2. In a flexible hinge or moveable joint for electrical purposes, the use of a
flexible metal cord or braid wound or employed on equi-distant and parallel tubes.
or bars, in the shape of an S or figure 8, or S reversed, forming a conducting
ligature, said ligature embracing or surrounding the said parallel bars, tubes, or
projections, so that the winding up of the flexible cord or braid on one bar will.
unwind it off the other bar, the said bar or tubes being also connected if desired
by one or more side lugs or links, or the said bars, tubes or the like may be
connected to knuckles which work to and fro in contact in a circular orbit as herein,
described and set forth.
Dated this 25th day of September 1896.
