PROVISIONAL SPECIFICATION.
Improvements in or connected with Lamp Burner Extinguishers.
I, HENRY JUSTUS CLARRY, of 259, Carlton Street, Toronto, Canada, Com-
mercial Traveller, do hereby declare the nature of this invention to be as
follows:-
This invention has mainly for its object to provide simple, cheap and effective
device and mechanism for extinguishing the flame of lamps of various sorts,
including lanterns.
According to this invention, I employ a sleeve sliding on the wick tube, and
connected by a lever or like device to the spindle employed for turning the wick
up and down, this spindle being so adapted that it is capable of being moved to
and fro longitudinally as well as rotated.
When a lever is used to actuate the sliding extinguisher, it is bifurcated and
grasps said extinguisher, or takes hold of same, at each side where it is provided
with a projecting part in connection with which the ends of said lever work. The
lever may be mounted, suitably, to the perforated or equivalent part of the
burner.
The spindle which actuates the wheels which turn the wick up or down, passes
freely through the said wheels or wheel bush, and is of angular section, or so
formed that it will rotate said turning wheels when it is rotated.
The action is, that to extinguish a lamp, the turning spindle is either pulled
outwards or pushed inwards, when the extinguishing tube will be raised through
the lever connecting it, and will put out the light.
The invention as above stated, may be applied to various forms of lamps and
lanterns and may be modified in different ways to suit the different conditions of its
application and other requirements.

COMPLETE SPECIFICATION.
Improvements in or connected with Lamp Burner Extinguishers.
I, HENRY JUSTUS CLARRY, of 143 Sparks Street, in the City of Ottawa, in the
Province of Ontario, Dominion of Canada, Commercial Traveller, 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:-
My invention relates to devices to be applied to lamp burners for the purpose of
extinguishing the flame when desired.
Fig. 1 is a sectional perspective through a burner having my improvements
applied, intersecting the flat wicktube transversely.
Fig. 2 is a transverse section through a burner taken at a right angle to Fig. 1
and showing the wicktube in elevation.
Fig. 3 is a similar section, showing the wicktube sleeve raised, and
Fig. 4 is a perspective view of the lever..
above
A is an ordinary burner provided with hood A. On the flat wicktube a,
the diaphragm a', is a sleeve B of about the same height as that part of the wick-
tube projecting above the diaphragm. On each side of said sleeve is secured a
tubular lug b. The cog wheels c are not, as usual, secured direct upon the wick

raising spindle, but are secured upon a square sleeve c¹ in which the square
spindle C may slide freely and yet turn it and the wheels with certainty. The
square spindle is provided with a milled head el, as usual, and is adapted to both
turn and slide in its bearings. Near the free end of the spindle is provided a square
shouldered neck or bearing e, adapted to engage into a slot and turn therein and
without leaving it when drawn forward or backward. D is a lever having its
fulcrum at the notches d, by which it is inserted into a slot in the rim of the
burner, the part below said notches being curved in and having in its end a slot d¹
for the reception of the neck of the spindle C. The part above said notches is
bifurcated to clip loosely the sleeve B, its tines being inserted in the tubular
lugs to work freely. The tines may be slightly curved, as shown, and the whole
lever may have considerable elasticity.
It will be observed that the spindle C may be turned to raise or lower the wick
as usual. But when it is desired to extinguish the flame (Fig. 2), the spindle is
drawn out, thereby pulling the lower end of the lever D nearer the base of the
burner and thus elevating the tines d" and with them the sleeve B, as in Fig. 3.
The sleeve thus raised above the upper edge of the wicktube a, while the wick
is being held stationary in the latter, has the same effect as lowering the wick
in the wicktube, only more effectively so, an effect which is well known by users of
lamps.
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:
1. A movable sleeve on the wicktube of a lamp burner adapted to form an
extension thereof, and means for temporarily raising said sleeve and forming said
extension, substantially as set forth.
2. The combination with a lamp burner of a square spindle, a square sleeve
fitting said spindle slidingly carrying the cog wheels for lifting the wick, and said
spindle having a square shouldered journal at its free end, the sleeve surrounding the
upper free part of the wick tube and sliding freely upon the same and provided
with tubular lugs and a lever fulcrumed in the rim of the burner and having its
lower part slotted and engaged by the journal of the square spindle and its upper
part Bifurcated and the tines passing through the tubular lugs on the sleeve,
substantially as set forth.
3. The combination of the burner A having a wick tube a, a sleeve B surrounding
said tube and adapted to slide upon it, lugs on said sleeve, a square wick raising
spindle C having means to engage the lever at its free end, and the lever D'having
its lower end engaged by said spindle fulcrumed about the middle in the rim of
the burner and having its upper end bifurcated and engaging the lugs of the
sleeve B, substantially as set forth.
4. The combination of a burner A having a wick tube a, the sleeve B having
the lugs and the lever D fulcrumed in said burner rim and having the tines of
its bifurcated upper portion connected to said lugs b, substantially as set forth.
Dated this 15th day of February 1892.
