PROVISIONAL SPECIFICATION.
Improved Cup and Ball Joint for Gas Pendants and the like.
WILLIAM THOMAS KENT, 162, St. Helen's Avenue, Swansea, South Wales, Gas
and Hot Water Fitter, do hereby declare the nature of this invention to be as
follows:-
This invention is for use on all gas pendants and hanging lamps. It consists
of a metal cup and ball joint having two flanges with holes for bolts; one flange
is fixed on the top section of ball joints, the other on the bottom section;
between these flanges are placed metal springs; through the holes in flanges and
springs are placed metal bolts with heads on one end and threaded the other
ends. The threaded ends of bolts are screwed firmly, in one of the flanges either
top or bottom and fitting loosely in the other flange; the heads of bolts not
to touch the flange, thus allowing the ball joint to shove in any direction
but not to turn round.
I claim this improved ball joint has many advantages. The springs prevent-
ing the cup in which the ball swings being strained, it will save many leaks of
gas as the springs pressing between the two plates keep the hall part of the
joint bearing firmly in its cup socket; this will be found very useful in shops
where T pendants are fixed, by taking out the bolts and springs, screw up the
joint the ordinary way; then refix the bolts and springs the pendant will remain
in position, but will allow the ball joint to swing in its socket, thus preventing
many fires, as this improvement will keep the pendant from turning round.

WILLIAM THOMAS KENT, 162, St. Helen's Avenue, Swansea, South Wales, Gas
and Hot Water Fitter, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention Fig. 2 is for use on all gas pendants and hanging lamps. It
consists of a metal cup and ball joint having two flanges A with holes for bolts,
one flange is fixed on the top section of ball joint, the other flange on bottom
section of ball joint, between these two flanges A and A are placed metal springs C
through the holes in the flanges and springs are placed metal bolts D with heads
on one end and threaded the other end; the threaded ends of bolts are screwed

page_text: firmly in one of the flanges either top or bottom and the head ends of fitting
loosely in the other flange the heads of bolts must not touch the flange thus
allowing the ball joint to move in any direction but not turn round, the heads
of the bolts I can be made any shape; but must be larger than the bolts so
that they will not pass through the holes in the flange.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1st) That this improved ball joint has many advantages over the ball joint
Fig. 1, the springs pressing between the two flanges A and A keep the ball part
of joint bearing firmly in its cup socket these springs also preventing the cup
in which the ball swings being strained if the hanging pendant is given a blow.
2nd. The bolts which are easily detachable act as guides for the springs also
for keeping the ball joint from turning round, the bolts will will also prevent
the two sections of ball joint from being unscrewed or if by accident the sections
became unscrewed the heads of the bolts will keep the pendant or lamp from
falling down.
