PROVISIONAL SPECIFICATION.
Improvements in connection with the Burners of Miners' Safety
Lamps.
We, STEPHEN HENRY ELLIS, MARSDEN ELLIS, WILLIE ELLIS, trading as
Alfred Ellis & Sons, of Northgate Wakefield, Brass Founders do hereby declare
the nature of this invention to be as follows:-
Hitherto miners lamps burning paraffin oil have only been used to burn with a
round wick, the wick being enclosed by a round burner and held in position by a
screwed cap in one piece with a round hole through the centre so that on screwing
the cap down it revolves round the burner.
Now our invention is to provide for the use of a flat wick and burner which we
accomplish by making the cap in three pieces two of which are screwed together by
a male and fernale joint, and the third is a movable or loose disc of circular form
placed between the other two pieces of the cap before screwing together, this disc
is perforated to the same shape as the wick and burner so that the burner can pass
through and allows the cap to be screwed down without turning the wick or burner
by revolving round the disc. The inner cap which encloses the wick remains
stationary and the outer cap which is screwed down revolves round the stationary
cap. The centre piece may be made either concave or convex as may seem most
desirable.
This construction will give an improved light on all miners lamps burning
paraffin oil as the use of a flat wick instead of a round wick is a great advantage
and which can be attained by means of the cap formed us above described.
Dated this 29th day of October 1894.

COMPLETE SPECIFICATION.
Improvements in connection with the Burners of Miners' Safety
Lamps.
We, STEPHEN HENRY ELLIS MARSDEN ELLIS and WILLIE ELLIS trading
as Alfred Ellis & Sons of Northgate Wakefield Brassfounders 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:
Hitherto miners lamps burning paraffin oil have only been used to burn with a
round wick, the wick being enclosed by a round burner and held in position by a
screwed cap in one piece with a round hole through the centre so that on screwing
the cap down it revolves round the burner.
Now our invention is to provide for the use of a flat wick B and burner C which
we accomplish by making the cap in three pieces D E and F two of which are
screwed together by a male and female joint E and F and the third is a movable or
loose disc or cap D of circular form placed between the groove of the outer

page_text: portion of the cap E which is screwed into the lower portion of the cap F which
forms part of the oil vessel before screwing together this disc or cap D is perforated
to the same shape as the wick and burner so that the burner C can pass through
and allows the cap to be screwed down without turning the wick or burner by
revolving round the disc or cap.
The inner disc or cap D which encloses the wick B remains stationary and the
outer portion of the cap E which is screwed down revolves round the stationary
disc or cap D. The disc or cap D may be made either concave or convex as may
seem most desirable.
This construction will give an improved light on all miners lamps burning
paraffin oil as the use of a flat wick instead of a round wick is a great advantage
and which can be attained by means of the cap formed, as above described.
In order to better explain our said invention we will now describe the, drawings
which accompany this Specification.
Fig. 1 is an elevation of a miners safety lamp.
Fig. 2 is a section through Fig. 1.
Fig. 3 is a plan shewing the burner and vessel of a miners safety lamp.
Fig. 4 is a plan of the burner (full size)
portion of the cap E which is screwed into the lower portion of the cap F which
forms part of the oil vessel before screwing together this disc or cap D is perforated
to the same shape as the wick and burner so that the burner C can pass through
and allows the cap to be screwed down without turning the wick or burner by
revolving round the disc or cap.
The inner disc or cap D which encloses the wick B remains stationary and the
outer portion of the cap E which is screwed down revolves round the stationary
disc or cap D. The disc or cap D may be made either concave or convex as may
seem most desirable.

paraffin oil as the use of a flat wick instead of a round wick is a great advantage
and which can be attained by means of the cap formed as above described.
