page_text: I, The Honourable WILLIAM FREDERICK BARTON MASSEY-MAINWARING of
30 Grosvenor Place, in the County of Middlesex, Gentleman, do hereby declare
the nature of this invention to be as follows:-
My invention relates to means for extinguishing the flame of a hydro-carbon lamp
and inore particularly to that class of lamp which is fitted with an Argund or circular
burner.
For this purpose I place around the outer wick tube of an Argand burner two
semi-circular bands of metal in such manner that their upper edges will be level with
or slightly below the top edge of the wick tube when in their normal position and
I connect two corners of such semi-circular bands to the upper edge of the wick tube
by rivet or pin joints so that such bands may turn upon such joints until their
upper edges inect in a vertical line above the wick tube.
To the lower edge of each semi-circular band connect by a hinge joint the curved
edge of a semi-circular disc of metal to form the ends of the extinguisher and
I connect the corners of these semi-circular discs or ends together by means of bars
or bands pin jointed thereto and extending across the sides of the burner tube.
Or I form the lower edges of the semi-circular bands at an angle from their outer
lower edges to their inner upper edges and I form the semi-circular ends at an angle
from their inner lower edges to their upper outer edges and curve them to the
form of tho burner tube so that when the parts are in their raised position the
meeting edges of the semi-circular bands and of the semi-circular ends will form
mitre joints whereby I obtain a neater and more compact form to the extinguisher.
In order to extinguish tho flame of the lamp the two semi-circular bands are turned
upon their centres until their upper edges meet in a vertical line when they will form
an arched cap over the flame the semi-circular discs or ends forming the ends of the
cap and when returned to their normal position the parts will lie snugly out of the
way around the wick tube.
In order to give the desired movements to the extinguisher I connect one of the
cross bars or bands to the inner end of the ordinary extinguisher lever by means of a

page_text: link or otherwise or I fork the inner end of such lever and pin joint one arm or prong
of the fork to each side of the extinguisher or I cause each of such prongs to enter an
angular slot formed in each of the semi-circular bands in order to give the required
motions thereto. Or I may employ other suitable connections between the extinguisher
lever and the extinguisher and I may operate such extinguisher by means of any
suitable safety extinguisbing device but I preferably employ for this purpose the
means described in the specification accompanying my application for Provisional
Protection dated June 15, 1887 No. 8626.
In applying my invention to flat wick burners I form the two halves of the
extinguishing cap with fixed or rigid ends and I give motion thereto by means of
the forked extinguisher lever the prongs or arms of which preferably work in slots
or guides in or upon the two halves of the extinguisher and I sometimes form the
fork with a central part to force open the lower ends of the two half caps in order
to assist the rising action of the extinguisher.
The extinguisher may be fitted to a ring or fitting which can be applied to existing
burner wick tubes.

page_text: I, The Honorable WILLIAM FREDERICK BARTON MASSEY-MAINWARING of
30 Grosvenor Place, in the County of Middlesex, Gentleman, do hereby declare
the nature of this invention and in what mannor the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
My invention relates to means for extinguishing the flame of that class of
hydro-carbon lamp which is fitted with an Argand or circular burner.
And in order that my invention may be clearly understood and readily carried into
effect I will describe the same by the aid of the accompanying drawings, in the various
figures of which like parts are indicated by similar letters of reference.
Figure 1 is vertical section, Figure 2 is another vertical section drawn at right
angles to figure 1, and Figure 3 is a plan of a hydro-carbon Argand or circular lamp
burner showing my invention applied thereto. Figures 4 and 5 are two elevations
drawn at right angles to each other and Figure 6 is a plan of the extinguisher, and
fitting carrying it, apart from the burner. Figures 7 and 8 are elevations drawn at
right angles to each other, and Figure 9 is a plan of parts forming one half of the
extinguisher shown separately. In figures 1, 2 and 3 the extinguisher is shown out
of action, that is to say, in its lowered position, and in Figures 4, 5 and 6 it is shown
in position for extinguishing the flame. Figure 10 is a vertical section of the
oxtinguisher fitting separately.
Figures 11 to 19 show a slight modification. Figures 11 and 12 are two elevations
drawn at right angles to each other and Figure 13 is a plan showing the burner tube
fitted with above mentioned modification and representing the extinguisher out of
action. Figures 14, 15 and 16 aro similar views to Figures 11, 12 and 13, but
representing the extinguisher in position for extinguishing the flame, and Figures 17,
18 and 19 are respectively two elevations and a plan of parts forming one half of last
mentioned extinguisher.
In the drawings 1 have represented my improved extinguishing apparatus fitted to
a tube or fitting a, which can be applied to existing burner wick tubes.
I will first describe the form of extinguisher shown at Figures 1 to 10.
According to my invention I place around the outer wick tube b of an Argand
burner, or around the tube or fitting a, two semi-circular bands c of metal, in such
manner that their upper edges will be level with, or slightly below, the top edge of
the wick tube b when in their normal, that is to say lowered, position, and I connect
the two corners c', c', of such semi-circular bands c to the upper edge of the tube or
fitting a, or of the wick tube b, by rivet or pin joints, so that such bands c may turn
upon such joints until their upper edges meet in a vertical line above the wick tube b,
as shown at Figures 4, 5 and 6.
To the lower edge of each semi-circular band c, referring to the same in their
lowered position, I connect, by a hinge joint d, the curved edge of a semi-circular
disc e of metal, to form the ends of the extinguisher, and I connect the corners e' of
these semi-circular discs or ends e together by means of bars or bands f, pin-jointed
thereto and extending across the sides of the burner tube b.

page_text: In order to extinguish the flame of the lamp, the two semi-circular bands care
turned upon their centres at c¹ until their upper edges meet, as before described, in
a vertical line, when they will form an arched cap over the flame, the semi-circular
discs or ends e forming the ends of the cap, and, when returned to their normal or
lowered position, the parts will lie snugly out of the way around the wick tube.
In order to give the desired movements to the extinguisher I connect one of the
cross bars or bands to the inner end of the ordinary extinguisher lever g by means
of a link h, or otherwise, and such lever g may be operated by hand, or as shown in
the drawings, I may operate such extinguisher by means of a falling weight i
connected to the lever by a cord or chain j and normally carried by a support k
attached to the burner fitting as described in the specification of a former patent
granted to me dated June 15, 1887 No. 8626.

In the modification reprosonted at Figures 11 to 19 I somewhat modify the form of
the parts. In this case, and referring to the extinguisher in its lowered position,
I form the lower edges of the semi-circular bands c, as seen at Figure 11, at an anglo
from their outer lower edges to their inner upper edges, and I form the semi-circular
ends e at an angle from their inner lower odges to their outer upper edges and curvo
them to the form of the burner tube b or fitting a, so that, when the parts are in their
raised position, the meeting edges of the semi-circular bands c and of the semi-circular
ends will form mitre joints, whereby I obtain a neater and more compact form to
the extinguisher.

By the construction of parts herein described I am enabled to apply an extinguisher
to an Argand hydro-carbon lamp burner, in which the space between the burner tubo
and the chimney is somewhat contracted, and at the same time avoid interfering
seriously with the passage of air to the flame in the normal, that is to say, the
lowered, position of the extinguisher.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :
1. In hydro-carbon Argand lamp burners, an extinguisher consisting of two
semi-circular bands e pivotted at adjacent corners to the wick tube, (or to a ring
or tubular fitting mounted on the wick tube) and connected by hinges d to semi-
circular ends e, which latter are connected together at their lower edges, and are
connected by a link to an operating lever g substantially as herein shown and
described.
2. An extinguisher constructed in the manner referred to in claim 1, in combination
with an operating falling weight i and support k, or with other automatic operating
means substantially as herein shown and described.
Dated this 8th day of November 1888.
