do hereby declare the nature of this invention to be as follows :--
An improved wick tube baveing a bell end which with the aid of capiliary attraction
allows the oil to travil more freely up to the burning point of the tube.
The wick tube also haveing a knuckle or indentation which prevents the wick from
falling into the oil Vessel or Lamp bottom, thus secureing a more uniform and better
light as long as any oil remains to be burned in the oil vessel.
Also the ring which supports the Gauze and which I call the main ring has a deep
coller which surrounds the bottom end of the Gauze on the outside thus protecting
the flame from direct currants of air, as well as any outside pressure.
Also in the inside of the Gauze is a corrosponding deep ring, screwed into the above
main ring and impinging on the inside and bottom end of the Gauze thus secureing
the bottom end of the gauze from any pressure arising from accident, bar breakage,
also from injury from direct contact with the flame of the Lamp.
This main ring which carries and supports the gauze also carries and supports the
Glass cylinder, and thus said ring screws into the lamp in its entireity and holds
and governs the positions of both the gauze and glass cylinder, and when you screw
out this ring which carries the gauze you screw at the same time loosen and take out
the glass cylinder thus facilitating the means of cleaning the glass and renewing
broken glasses.
When the gauze and glass cylinder is put in position and the said main ring is
screwed up
it enters the Lamp wholly and is not kept in position by any other means,
but is shut in the inside of the Lamp and thus adds to the safety of the Lamp.
I must also remark that the air enters the lamp is a very indirect way thus breaking
the current, and it has to pass through this said main ring which carries and controls
both the gauze and glass cylinder above alluded to or I cause the air to support
combustion to pass into the Lamp above the glass cylinder.
The upper part of the Lamp is protected in the usual way by a shield or bonnet.

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 Miners Safety Lamps and has for its object
the construction of a lamp which shall in the first place give a good light. In the
second be a safe lamp even when placed in currents of air and gas forming a highly
explosive mixture and travelling at a rapid rate.
Thirdly to be simple and of few parts easly taken to piecies to examine and
casly and securely put together again.
To accomplish this I make it in the following manner. a. is the lamp bottom or oil
vessel is the wick tube having a bell end shaped bottom so as to allow the oil or
other illuminant to flow up freely. C. is a projection in the wick tube to prevent the
wick from falling into the oil vessel should the lamp be subject to a sudden jerk or
knock d I call the body of the lamp which is held together by three or more brass or
iron pillars and marked e.
In the body of the lamp is placed a glass cylinder f. which is held in position by a
screw ring G and this said ring is also the conductor of air into the lamp to support
combustion, the air enters first in the body of the lamp in a vertical direction through
holes into the air chamber H. then through holes in the ring G which holes are
marked J. The ring G is also the seat of the circular wire gauze K. which fits
'tightly in circular collar L. which collar also forms a barrier for the air to impinge
upon and prevents its direct action on the flame thus materally adding to the safety
of the Lamp.
The top of the circular wire gauze I make solid by fixing a male and female top
made of copper brass or other suitable material marked M, between these plates I fix a
layer of asbestos or other non-conductor of heat N. I then rivet or otherwise fasten
together the gauze asbestos male and female circular copper which forms a solid
top 0.
P. is a moveable shield or bonnet which screws into the body of the lamp, this can
be easily screwed off to examine the gauze, the said bonnet when screwed on again
is prevented from going past its locking point by having a stop fixed in the body of
the lamp out of sight which is marked Q with a corrospondings top in the recess in
the ring of the bonnet also marked Q. It will at once be obvious that these stops
can be placed vice-versa if preferred when the said bonnet is screwed home to make
it secure I push into a recess a vertical rod moving in the body of the lamp and
marked R. and keep it there by a horizontal screw which also locks the bottom
or oil vessel a. or I use a horoizontal plain sliding bolt with a plug passing through a
hole behind the bolt, Fig. I and II marked V.

page_text: The top of the bonnet is made to move on a hinge by a hasp S. by this means
greater facility for the escape of the products of combustion is provided and the lamp
is kept cool by a current of air passing through the lamp.
The gauze is held in its place by a sliding clip of brass copper or other suitable
material and is marked T this is moved to and fro by the finger and thumb and
working on a pin screw or rivet marked W.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. The wick tube with bell shaped end and indentation to prevent wick falling
into oil vessel.
2nd. The mode of admitting air into the lamp, to support combustion first through
vertical holes into a chamber then through openings made in an inner ring.
3rd. An inner ring supporting and controlling glass cylinder and gauze.
4th. A gauze with a solid metal top and layer of asbestos as applied to Miners
Safety Lamps of this type.
5th. A vertical rod which secures the bonnet to the body of the lamp with its
horozontal screw and bolt which secures the oil vessel of this type of Lamp.
6th. The moveable hinged top as applied to bonnetted lamps of this particular
Туре.
7th. The sliding clip of brass copper or other metal with its pin screw or rivet to
hold gauze in position.
I claim the above combination of parts forming the improved Miners Safety Lamp
arranged to act substantially in the manner herein before described and represented
in Figs. 1 and 2 of the drawings hereto annexed, as applied to Safety Lamps of the
type heretofore described.
And I state further that the claims as mentioned 4-5 & 6 are limited to use in
combination with the particular arrangements described in the provisional
Specification.
