PROVISIONAL SPECIFICATION.
Improvements in and connected with Ball Joints for Gas Pendants.
I, JAMES HENRY HARRISON, of 5, Warren Street, Stockport, in the County of
Chester, Gas-fitter, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in and connected with ball joints for
gas pendants and has for its object to provide means which, should the ball joint
leak through wear or other causes, prevent the escape of gas.
To this end my invention consists in combining with the said ball joint means
for sealing it.
According to one form of my invention I furnish or form the pipe of the pendant
near the ball joint with a cup or vessel adapted to surround the same and to contain
a suitable fluid or fluids which serves to seal the ball joint.
According to another form of my invention I may furnish or form the stationary
part of the ball joint with a bonnet adapted to project into the said cup or vessel
and cause the fluid or fluids therein to form a double seal.
When using glycerine to seal the said ball joint it may be utilized as a lubricant
for the ball joint by forming or furnishing the movable part of the ball joint
internally with a tube which reaches above the level of the glycerine in the said
cup or vessel and prevents the glycerine entering the pipe of the pendant.
Dated this 24th day of November 1896.

Improvements in and connected with Ball Joints for Gas Pendants.
I, JAMES HENRY HARRISON, of 5, Warren Street, Stockport, in the County of
Chester, Gas-fitter, 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 relates to improvements in and connected with ball joints for
gas pendants and has for its object to provide means which, should the ball joint
leak through wear or other causes, prevent the escape of gas.
To this end my invention consists in combining with the said ball joint means
for sealing it.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings, marked with letters of reference

page_text: indicating like parts in the various figures, representing longitudinal sections
of various forms of my invention.
a is the pipe or movable part and 6 the stationary part of the ball joint of the
gas pendant which apart from my improvements is constructed as hitherto.
In carrying out my improvements, according to one form of the same, Fig. 1,
I furnish or form the pipe or movable part a of the pendant near the ball joint
with a cup or vessel c adapted to surround the latter and to contain a suitable fluid
or fluids d, say mercury, water or oil, or water and oil, which serves to seal the
ball joint.
According to another form of my invention, Fig. 2, I may furnish or form the
stationary part b of the ball joirt with a bonnet e adapted to project into the
cup or vessel c and cause the fluid or fluids d therein to form a double seal.
When using glycerine it may be utilized as a lubricant for the ball joint by
forming or furnishing the pipe or movable part a of the ball joint, internally with
a tubular extension f which reaches above the level of the glycerine in the cup
or vessel c and prevents the glycerine entering the pipe of the pendant.
The cup or vessel c may be secured to or formed on the pipe or movable part a
of the pendant in any convenient manner, say screwed or soldered on and instead
of being of metal it may be made of rubber with a flange c¹ at its lower end, as
shown in dotted lines, Fig. 1, to grip the pipe or movable part a of the pendant,
as will be readily understood.
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. In combination with a ball joint of a gas pendant, a cup or vessel e adapted
to hold fluid or fluids which serve as a seal for the ball joint, all substantially
as set forth.
2nd. In combination with a cup or vessel c, specified in the preceding
claim, a bonnet e on the stationary part 6 of the ball joint of the gas pendant,
all substantially as and for the purpose set forth.
3rd. In combination with a cup or vessel c, specified in Claim 1, a tubular exten-
sion f on the upper end of the pipe or movable part a of the ball joint of the
gas pendant, all substantially as set forth.
Dated this 16th day of August 1897.
