PROVISIONAL SPECIFICATION.
An Anti-vibration Cup and Ball and Anti-vibration Connector Gas
*Fitting.
JOHN BAKER COLBRAN, Gas Lamp Manufacturer, 58 & 59, Chiswell Street,
Finsbury, E.C., do hereby declare the nature of this invention to be as follows:-
The first part of my invention relates to the anti-vibration cup & ball & con-
sists in converting the present form of cup & ball into an antivibration cup &
ball as follows.
I
Lengthwise through the tail of the ball I make a large hole leaving only a
thin tube to form the tail. I provide a round spindle the diameter being slightly
smaller than hole through tail of ball. On one end of spindle is formed a pro-
tecting cap & through spindle lengthwise I provide a small hole for gas way.
provide an open spiral spring about half the length of spindle (or in some case
I may use a piece of india rubber tube- to form a buffer) & with core slightly
larger than diameter of spindle so that the spring can be slid over the spindle
and one end caused to butt against projecting cap the spindle can then be inserted
into hole in tail piece of ball from the ball end of tail thus bringing the bottom
end of spring to butt against the inside of ball so that the spindle passes loosly
through spring, ball, & tail & is supported by the top cap resting on top of
spring while the bottom end of spring is resting on the inside of ball the spindle
is of sufficient length to project beyond the tail of ball at the end of tail I
pro-
vide an ordinary stuffing box through which the spindle passes making a gas
tight joint. The lamp or fitting is then attached to the spindle & the whole
lamp or fitting being thus suspended is carried by the spring.
The second part of my invention relates to the anti-vibration connector gas
fitting which is a substitute for the cup & ball before described and in some
parts is similar but dispensing with the ball I use the cup and spindle only.
The cup is made with a taper hole at bottom enlarging outwards with a thin
bush round hole on the inside of cup the diameter of hole at small end is
slightly larger than the spindle which slides loosely through it. The spindle has
a projecting cap on end with a thin bush on the outer edge of cap thus forming
a capsule over top of spindle. I provide a piece of india rubber tube about half
the length of spindle which fits loosely over it & butts against the cap at end
of spindle the bush on outer edge of cap spanning over the tube the other end
of tube is stretched over the thin bush on the inside of cup the spindle is then
supported by the india rubber tube the ends making gas tight joints.
It will thus be seen that the effect of any concussion to the support or fixing
will not be transmitted to the lamp or fitting but will by the means of this
anti-vibration cup & ball or the connector gas fitting be reduced to a minimum.
Dated the 9th day of December 1898.

-Fitting.
JOHN BAKER COLBRAN, Gas Lamp Manufacturer, 58 & 59, Chiswell Street,
Finsbury, E.C. I 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 first part of my invention relates to the anti vibration cup & ball and
consists in converting the present form of cup & ball into an anti vibration
cup & ball as follows Fig. 1.
Lengthwise through the tail of the ball a a¹ I make a large hole leaving only
a thin tube to form the tail. I provide a round spindle the diameter being
slightly smaller than hole through tail of ball, on one end of spindle is formed
a projecting cap C and through spindle lengthwise I provide a hole H for gas
way I provide an open spiral spring S straight or bellied about half the length
of spindle (or in some cases I may use a piece of india rubber tube to form a
buffer) and with core slightly larger than diameter of spindle so that the spring
can be slid over the spindle and one end caused to butt upon projecting cap C
the spindle can then be inserted into hole in tail piece of ball a a' from the
ball end of tail thus bringing the bottom end of spring S to butt against the
inside of ball so that the spindle passes loosely through spring ball & tail and is sup-
ported by the cap C resting on top of spring while the bottom end of spring is
resting on the inside of ball a the spindle is of sufficient length to project
beyond the tail of ball a a', at the end of tail a a¹ I provide an ordinary stuffing
box d through which the spindle passes making a gas tight joint the lamp or
fitting is then attached to the spindle and the whole lamp or fitting being thus
suspended is carried by the spring.
The second part of my invention relates to the anti-vibration connector gas
fitting which is a substitute for the cup & ball before described and in some parts
is similar but dispensing with the ball I use the cup and spindle only as follows
Fig. 2.
The cup e is made with a taper hole f at bottom enlarged outwards with a
thin bush K round hole the inside of cup the diameter of hole
at small end is slightly larger than the spindle L which slides loosely
through it the spindle Ļ is provided with a projecting cap M on
end with a thin bush on the outside edge of cap I provide a piece of india
rubber tube N about half the length of spindle which fits loosely over it and
butts against the cap at end of spindle the bush on outer edge of cap spanning
over the tube N the other end of tube is stretched over the bush K on the inside
of cup e the spindle L is then supported by the india rubber tube N the ends
making gas tight joints a flanged socket P is screwed on the bottom end of
spindle L and butts against the underside of cup e which prevents the spindle L
rising and holds the india rubber tube N in its seats at M and K but allows the
spindle L to be drawn downward by the lamp or gas fitting attached to it a
gas way is provided through spindle L.
It will thus be seen that the effect of any concussion to the support or fixing
will not be transmited to the lamp or fitting attached to antivibration cup & ball
or connector gas fitting but will be reduced to a minimum.

page_text: 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. The loose spindle or tail running through ball of the anti vibration cup
and ball and the loose spindle through the cup of antivibration connector gas
fitting.
2nd. The spring or india rubber buffer as described.
3rd. Also the combination of parts as before described.
