PROVISIONAL SPECIFICATION.
Improvements in Gas Fittings.
1 JAMES FAIRBANK of 43 Murray Street Hoxton in the City of London
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in gas fittings and has for its object
the prevention of waste of gas while alight and the escape of gas when not
burning.
When new fittings are employed I arrange that the cock is constructed with
locking devices by means of which the gas is turned off to the lowest limit without
fear of extinction and locked there if it is desired to leave it burning or if it is to
be extinguished entirely the cock is pressed past the first lock on to the second
where it is firmly and cannot be knocked on by accident or turned too far, as is
often the case with ordinary cocks, opening the port again and allowing gas to
escape and which is all but undiscernible in a room after the light is extinguished.
In order to apply my invention to existing gas fittings I construct a spring of
brass or other suitable material having notches grooves or stops at one end and a
clipping apparatus at the other end for securing it to the gas pipe. This spring
presses upon the tap and holds it firmly in the position in which it is placed and
answers in all ways the purposes above described.
Dated this 21st day of April 1891.
COMPLETE SPECIFICATION.
Improvements in Gas Fittings.
I JAMES FAIRBANK of 43 Murray Street Hoxton in the City of London
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 relates to improvements in gas fittings and has for its object
the prevention of waste of gas while alight and the escape of gas while not
burning.
It is not my intention to describe or make any claim on account of my invention
as applied to new fittings as announced in my Provisional Specification I am
content to describe and claim as my invention the device as applied to existing gas
fittings.
In order that my invention and the manner in which it is carried out may be
thoroughly understood I have appended a drawing of the same marked with letters
of reference.
A is the clip bent to suit any size of pipe to which the lock is to be attached.
B is the first stop.
C the second or lock stop.
D the thumbpiece for effecting the release of the tap.
This spring locking device is made of brass steel or other suitable material, the
notches, grooves or stops being formed by stamping up the metal into suitable
shapes or by other convenient methods. The clip A surrounds the gas pipe and is
firmly clenched on the same by means of a screw in it at such a distance from the
tap that when the tap is turned off the thumbpiece of the tap is held by or falls
into the lock stop C. In taking hold of the tap to turn the gas on the thumb is
pressed (almost involuntarily) upon the end D releasing the tan allowing the was

page_text: to be turned on and lighted. If the tap is now brought to the first stop B the
light will be diminished this forms a ready means of lowering the gas to a certain
point without thought or fear of extinction. On the tap being pressed beyond
stop B it at once falls into the lack stop C from which it can only be released by
pressure on the spring as before described. The gas is completely shut off and
there is no chance of the tap being accidentally opened.
Having now described my invention and the manner of its application and action
I declare that what I claim is
A spring locking and stopping apparatus attached to a gas pipe substantially as
described in reference to accompanying drawing.
Dated the 19th day of January 1892.
JAMES FAIRBANK.
