COMPLETE SPECIFICATION.
New or Improved Universal Joint or Coupling for Gas Pendants.
I, JOHN CHARLES BAYLEY, of the Firm of Bayley & Beeching, of Dene
House, Bournemouth, in the County of Hants, Ironmongers and Manufacturers,
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 :-
As heretofore constructed difficulty has been experienced in making and
maintaining the universal joints or couplings of gas pendants gas-tight, and this
difficulty is rendered even more serious where acetylene is being used.
Now my invention has for its object a universal joint designed to overcome this
objection and which therefore is particularly applicable for pendants employed for
burning acetylene which I preferably term "Acetyliers."
For this purpose I couple the two portions of the pendant by a universal
coupling of any suitable form capable of sustaining the weight of the lower portion
of such pendant, whilst I complete the passage between the interiors of said two
portions of the pendant by a length of rubber or other flexible tubing, the ends of
which are passed over or otherwise secured to the ends of the two portions.
The universal coupling employed for sustaining the weight of the lower portion
of the pendant may be of any suitable form, as will be understood, and my
invention is not limited to any particular type or construction, but in order that
my invention may be better understood and carried iuto practical effect I will
describe it by the aid of the accompanying drawings illustrating four different
forms of couplings. Like letters refer to like parts throughout these drawings.
The coupling shown in prospective in Fig. 1 consists of a pair of arms a secured
to or formed on the ends of each of the two portions 6 of the pendant and hinged
at diametrically opposite points to a ring c. The passage through the pendant is
completed through a length of rubber tubing d the ends of which are passed over
the ends of the two portions b.
Fig. 2 illustrates in vertical section a hollow ball and socket joint, the upper or
socket portion a of which is preferably so arranged that it may be slid upwards
when the parts are detached to pormit of the rubbor tubing d, which is arranged in
the same manner as in Fig. 1, being secured in position.
In Fig. 3 is shown in vertical section a coupling wherein the two portions 6 of
the pendant are coupled by a link through the ends of which pass pins secured in
the ends of the two portions bat right angles to one another, whilst in the joint
shown in section in Fig. 4 a short chain g is substituted for said link. In both
these arrangements the rubber tubing d completing the passage through the
pendant occupies the outer position and may if desired be of au ornamental form.
Having now particularly described and ascertained the nature of my said inven-
tion and in what mauner the same is to be performed, I declare that what I
claim is :-
(1) A universal joint or coupling for gas pendants in which communication
between the two parts coupled is effected through a length of flexible tubing
independently of that portion of said coupling sustaining the weight of the lower

page_text: (2) A universal joint or coupling for gas pendants substantially as described and
illustrated in the accompanying drawings.
