PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Lighting Gas.
We CHARLES LEIGH CLARKE of 35 Market Street, Manchester, Electrical Engineer
and ARTHUR BOLTON BRIGGS of 14 Chatham Grove, Withington, near Manchester,
Gentleman do hereby declare the nature of our said invention to be as follows:-
These improvements refer to the cage or receptacle containing occluding material
employed for gas lighting purposes as described in the Specification of Letters Patent
No. 466 and dated 10th January 1889, and consist in so mounting the said cage or
receptacle upon a hinge or pivot with regard to the burner that in its normal position
its contents shall be out of contact with the issuing gas flame, but which shall
be capable of being turned into contact with the issuing gas only at the instant of
lighting the gas.
In carrying out our invention and as applied to existing gas burners we employ
a clamping device for surrounding and securing the apparatus to the burner.
To the side of this clamp the cage or receptacle is hinged and has a constant
tendency imparted to it, to turn on one side at a suitable angle from the perpendicular
so as to be out of the way of the gas flame as aforesaid, either by weighting the cage
on one side by the application thereto of a spring, by the expansion of a metallic rod
or in any other equivalent manner.
We provide also an arm from the extremity of which a short length of chain
depends and so is conveniently disposed to enable the cage to be drawn at pleasure
into contact with the issuing gas at the instant of lighting the jet.
In other cases the receptacle is hinged directly to a stud projecting from the
burner itself.
This 15th day of November 1889.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Lighting Gas.
We CHARLES LEIGH CLARKE of 35 Market Street, Manchester, Electrical Engineer
and ARTHUR BOLTON BRIGGS of 14 Chatham Grove, Withington, near Manchester,
Gentleman do hereby declare the nature of our said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following stateinent :-
These improvements refer to the cage or receptacle containing the occluding
material employed for gas lighting purposes as described in the Specification of
Letters Patent No. 466 and dated 10th January 1889, and consist in so mounting
the said cage or receptacle upon a hinge or pivot with regard to the burner that in
its normal position its contents shall be out of contact with the issuing gas flame,
but which shall be capable of being turned into contact with the issuing gas only at
the instant of lighting the gas.
On the accompanying drawing
Fig. 1 is a front view of our improved gas lighting apparatus applied to an existing
gas burner shewing the cage in its normal (or inclined) position out of the way of

page_text: All the views are drawn on an enlarged scale to shew the parts more clearly.
The improved apparatus consists of a frame a provided at the rear with a clasping
device b for surrounding and securing the apparatus to the ordinary gas burner cand
which is conveniently effected by tightening the.clamping screw d.
To the front of this frame a the cage or receptable e (containing the occluding
material and fitted with the fine platinum or other wire described in the Specification
of Letters Patent No. 446, A.D. 1889 as aforesaid) is hinged or pivoted being mounted
horizontally upon the stud f.
The cage c so mounted has a constant tendency imparted to it to turn on one side
át a suitable angle (as seen in Fig. 1.) from the perpendicular. so as to be out of the
way of the gas flame by weighting it on one side by a weight g and on the opposite
side the cage is provided with an arm h from the extremity of which a short length
of chain depends and so is conveniently disposed to enable the cage e to be drawn
at pleasure into contact with the issuing gas (see Figs. 2, 3 and 4) at the instant of
requiring to light the jet and which chain when let go again allows the apparatus to
resume its original position as seen in Fig. 1.
As applied to new gas burners the stud / projects from or is secured directly to
the burner itself.
Instead of weighting the cage to cause it to turn on one side it will be apparent
that a spring might be substituted or the expansion of a metallic rod or other
equivalent. means be employed for causing the cage to retire out of the way. In
this manner and by the use of this our improved gas lighting apparatus we secure
greater longevity or durability in the occluding material employed and especially
that when the gas is of poor quality and contains much sulphur it shall not have time
to injuriously affect the occluding material.
Having thus particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1st. The improved gas lighting apparatus substantially as and for the purposes herein-
before described and illustrated on the accompanying drawing.
2nd. In apparatus for lighting a gas burner the employment of an occluding cage
so mounted upon the burner and capable of being drawn into contact with the issuing
gas at the instant of lighting the same substantially as herein before described and
illustrated on the accompanying drawing....
