PROVISIONAL SPECIFICATION.
Improvements in and connected with Wick Winders for Oil Lamps
and Stoves.
I, ALBERT EDWARD HANCOCK, of 105, Finch Road, Handsworth, in the County
of Stafford,. Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention consists of the herein described improvements in and connected
with wick winders for oil lamps and oil stoves. Oil lamps and oil stoves are at
present often extinguished by winding the wick down into the wick tube, but
unless this is carefully done there is a risk of the wick being wound down too
low and igniting the oil or vapour in the oil vessel and causing an explosion.
The object of my invention is to provide means which will limit the downward
travel of the wick and thus make it impossible to wind the wick down too low
into the wick tube when extinguishing the lamp or stove.
In carrying out my invention provide a cam or stop piece mounted loosely
on the wick winder spindle and made with inclined clutch teeth which engage
with corresponding inclined clutch teeth formed on the face of the milled knob
by which the winder spindle is turned, a suitable spring keeping the clutch in
gear. The cam or stop piece is by preference made in the form of a disc with
a certain part of the periphery cut away the terminations of this cut away part
forming stops which as hereinafter described come in contact at certain times with
a stationary projection fixed on the lamp or stove.
My invention as above in part described acts as follows:-On turning the
winder in the direction to raise the wick, one of the stops of the cam piece comes
in contact with the said stationary projection which arrests the rotation of the
cam piece, but the teeth are so shaped that this does not interfere with the turning
of the winder in the direction to raise the wick. After the wick has been lighted
and the winder turned in the direction to turn the wick down into the wick tube
the cam piece is carried round by the teeth of the cam piece until when the
wick has been turned down far enough to extinguish the flame the other stop of
the cam piece comes in contact with the stationary projection on the lamp or
stove which arrests the rotation of both the cam piece and the winder and the
further downward movement of the wick, as the ratchet teeth will not permit
of the winder turning in this direction whilst the teeth are in gear.. Thus any
accidental turning of the wick down too far is effectually prevented.
If for the purpose of removing or cleaning the wick it is desired to turn the
wick further down the wick tube this can readily be done by pushing the cam
piece longitudinally along the winder spindle so as to disengage the clutch, teeth
and then the winder can be turned in either direction independently of the cam
piece.
Instead of the inclined toothed clutch which I have described for driving the
cam piece in one direction by the winding of the winder and for preventing the
cam piece turning when the winder is turned in the other direction, other

page_text: equivalent arrangements of mechanism may be employed for this purpose such
for instance as a click or ratchet on one part which engages with inclined or
other teeth on the other part.

Improvements in and connected with Wick Winders for 0.1 Lamps
and Stoves.
I, ALBERT EDWARD HANCOCK, of 105, Finch Road, Handsworth, in the County
of Stafford, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention consists of the herein described improvements in and connected
with wick winders for oil lamps and oil stoves. Oil lamps and oil stoves are at
present often extinguished by winding the wick down into the wick tube, but
unless this is carefully done there is a risk of the wick being wound down too
low and igniting the oil or vapour in the oil vessel and causing an explosion.
The object of my invention is to provide means which will limit the downward
travel of the wick and thus make it impossible to wind the wick down too low
into the wick tube when extinguishing the lamp or stove.
I will describe my invention by referring to the accompanying drawings on
which Fig. 1 is a side elevation of an oil stove burner with my invention applied
to the wick winder; Figs. 2 and 3 are cross sectional elevations of the same;
Fig. 2 shewing the wick wound up as when the stove is burning and Fig. 3 shew-
ing the wick wound down as when the stove is extinguished; Fig. 4 is a sectional
elevation of the part of the wick winder of the burner represented in Fig. 1
which embodies my invention; Fig. 5 shews the same parts as Fig. 4 but with
a certain portion pushed back to permit of the wick being wound either up or
down to any extent as hereinafter described; Figs. 6 and 7 shew parts of my
invention; Fig. 8 illustrates a slight modification of the same; and Fig. 9 shews
a part of the same.
The same letters of reference indicate the same or corresponding parts in all
the figures.
In carrying out my invention I provide a cam or stop piece A mounted loosely
on the wick winder spindle B and made with inclined clutch teeth a' at one end
which engage with corresponding inclined clutch teeth formed on the inner
face of the milled knob C which is fixed on the end of the wick winder spindle B
and by which said spindle is turned. The clutch teeth a' c are kept in gear by a
small coiled spring D enclosed in the stop piece A and arranged round the wick
winder spindle B so as to act between the collar E which is fixed on the wick
winder spindle and the collar part 2 of the cam or stop piece A. The cam or
stop piece A is at a made like a disc with a certain part of the periphery cut
away the terminations at a³ of this cut away part forming stops which as herein-
after described comes in contact at certain times with the stationary projection F
which is fixed to any convenient part of the lamp or stove; in the particular
burner shewn the projection F is represented as fixed to the base of the burner.
The part of the disc piece a³ which has been cut away to form the stops a* a³ is
indicated by diagonal shading lines in Fig. 9.

page_text: My invention as above in part described acts as follows:-On turning the wick
winder knob C and spindle B in the direction to raise the wick H that is as
indicated by the arrow in Fig. 2, the stop at of the cam piece comes in contact
with the stationary projection F which thus arrests the rotation of the can
piece A but the ratchet teeth ac are so shaped that this does not interfere with
the turning of the wick winder spindle B in the direction to raise the wick to the
proper height to give the proper flame. After the wick H has been lighted and it is
desired to extinguish the light the winder knob C and its spindle B are turned in
the direction to turn the wick H down into the wick tube I as indicated by the arrow
in Fig. 3 so that the cam piece A is carried round by the ratchet teeth a' c¹ until
when the wick H has been turned down far enough to extinguish the flame as
shewn in Fig. 3 the stop a of the cam piece comes in contact with the stationary
projection which thus arrests the rotation of both the cam piece and the
winder spindle B and the further downward movement of the wick H, as the
ratchet teeth a' c¹ will not permit of the winder spindle B turning in this direc-
tion whilst the said ratchet teeth are in gear. Thus any accidental turning of
the wick H down too far is effectually prevented.
If, for the purpose of removing or cleaning the wick H it is, required to be
turned further down into the wick tube I this can readily be done by pushing
the cam piece A longitudinally along the winder spindle B as shewn in Fig. 5
so as to disengage the clutch teeth a from the clutch teeth and then the winder
knob Cand spindle B can be turned in either direction independently of the
cam piece A.
Instead of the inclined teeth c which I have described for driving the cam
piece A in one direction by the winding of the winder B and for holding the
cam piece and the winder together when the winder is turned in the other direc-
tion as far as the stop and stationary peg F will allow, other equivalent
arrangements of mechanism may be employed for this purpose such for instance
as the click or ratchet J fixed on the interior of the knob C the end of which
engages with the inclined or other teeth a¹ on the cam piece A; or instead of the
click or ratchet J being fixed on the knob C the click or ratchet may be carried
by the clutch piece A and arranged to gear with the inclined teeth c¹ of the
winder knob C the action on the wick winder spindle B for controlling the
winding down of the wick being the same as above described.
My invention is applied to the wick winders of the burners of duplex and other
oil lamps and stoves similarly as above described with reference to the winder of
a single wick burner of an oil stove.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The combination, with the wick winder of an oil lamp or stove, of a cam
piece mounted loosely on the winder spindle and made with stops and a clutch
or the like arranged to cause the cam piece to revolve with the knob of the winder
spindle in either direction, a stationary projection on the burner with which the
said stops will engage, said parts being so arranged that when the clutch is in
gear and the knob of the winder spindle is turned to lower the wick and extin-
guish the flame, one of the stops of the cam piece comes in contact with the
said stationary projection and arrests the turning movement of the winder spindle
and the descent of the wick, and thus prevents the wick from being turned down
too far, substantially as described.
2. The combination with the wick winder of an oil lamp or stove, of the cam
piece A mounted to revolve loosely on the winder spindle and made with stops
as as and clutch a', the knob C fixed on the spindle B and made with teeth c¹ to
engage the clutch, a stationary projection on the burner with which the stops a* a³
will engage, the coil spring 1) acting between the collar E on the winder spindle
and the collar a² of the cam piece so as to keep the clutch teeth in gear but

page_text: permit of their being pushed out of gear when desired, said parts being so
arranged that when the clutch is in gear and the knob C of the winder spindle
is turned in the direction to raise the wick the clutch teeth will pass one over
the other when the stop comes in contact with the stationary projection but
when the winder spindle has been turned in the opposite direction to lower the
wick and extinguish the flame the stop comes in contact with the stationary
projection and arrests the turning movement of the winder spindle and the
descent of the wick thus preventing the wick from being turned down too far,
substantially as described and illustrated.
