Improvements in Wick Raisers.
A communication from abroad by CHARLES STANFORD UPTON, of 42, Park
Place, in the City of New York, State of New York, United States of
America, Manufacturer.
I, CHARLES AUBREY DAY, of 321, High Holborn, in the County of London,
Chartered Patent Agent, 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 the operating of wicks in central draft lamps, and is an
improvement on wick-raisers.
The main object of the invention is to provide a simple and effective means of
putting the wick on and taking it off what is known as the wick-carrying sleeve,
which surrounds the central draft air tube, and to hold fast the wick in a fixed
position on the said wick-carrying sleeve, without the use of bands, ties or holders.
It also is intended to avoid the use of friction bands in said wick-carrying sleeve
so that the sleeve with wick will remain in any position set. The invention is
especially adapted to the style of central draft lamp known as "The Rochester,"
wherein the complete wick-raising device is lifted out of the oil reservoir through
a slot in the neck, but the invention can also be used in other central draft lamps,
by providing a slip joint between the wick-carrying sleeve and the off-set handle.
In the accompanying drawings:-
Fig. 1 is a view of a central draft lamp with wick-raising sleeve shown in elevation
surrounding the central draft air tube, the wick being in part cut away. The
central draft air tube is shown surrounded by the wick, as it passes up through
the lamp body and on top of the same is shown the perforated thimble or cone
burner.
Fig. 2 is a view of my wick-carrying sleeve, out of the lamp, but in position as if
in place, made in two longitudinal sections or parts, with the operating handle
attached.
Fig. 3 is a view of my wick-carrying sleeve, made in two sections, with the top
sides pressed together ready to receive the wick.
Fig. 4 is a plan view of Fig. 2, showing the hinge joint connecting the two
longitudinal sections of the wick-carrying sleeve, on opposite sides, and also showing
the hinge joint which fastens the offset handle at its lower end to said wick-carrying
sleeve.
Fig. 5 is a detail view of the joint, showing how the two or more sections of the
sleeve are hinged together, on the sides thereof.
Fig. 6 shows my wick-carrying sleeve made in four sections.
Referring to the views in detail, A in Fig. 1, is the oil reservoir, b is the
perforated thimble or cone burner, surmounting the central draft air tube at its
upper end, c is the gallery or removable part of burner, d is the slot in the neck of
oil reservoir, through which the off-set handle e is operated, fand f' are the two
parts of the wick-carrying sleeve and g is the air tube, h is the wick.
In Figs. 2, 3 and 4, i is the joint where the off-set handie e is fastened by a hinge
to one part of the sleeve f¹, and j and j' are the rivets by which the two halves of
the wick-carrying sleeve f and fare hinged together. and are the projecting
points on top of the edges of wick-carrying sleeve, whereby the wick is held in

page_text: place. The hinged joint in the wick-carrying sleeve is shown in Figs. 4 and 5,
where j and j' are the rivets, and f and the longitudinal sections or parts of the
sleeve.
I have shown in the drawings the wick-carrying sleeve, made in two longitudinal
sections or parts, which is the preferred construction; this sleeve, however, can be
made in more than two longitudinal parts or sections, as shown in Fig. 6.
It will be seen that the invention consists in making the wick-carrying sleeve in
two or more longitudinal parts (and f¹) and connecting by a rivet through each
of the ear pieces and (Fig. 5) in form of a pivoted or hinged joint near the
middle, axially at right angles to the central air tube, so that when the top parts
of the sleeve are pressed together as in Fig. 3, the wick will slide on over the
points and k, easily. Then when the wick-carrying sleeve with wick over the
same is slipped on over the air tube g, the longitudinal parts of the wick-carrying
sleeve and fat the top are forced apart, and assume the position shown in Fig. 2,
and the projecting points k and immediately engage the wick as shown in
Fig. 1 and hold it firmly in place, and it is raised or lowered whenever the wick-
carrying sleeve is operated by the off-set handle e.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. In a central draft lamp a wick-carrying sleeve made in two or more
longitudinal sections, and a pivoted or hinged joint connecting the parts of said
sleeve, substantially as described.
2. The combination in a central draft lamp of the central air tube, a wick-
carrying sleeve made in two or more longitudinal sections hinged together and
surrounding said air tube, holding points on the top edge of said sleeve, and an
operating handle attached thereto, substantially as described.
3. The combination in a central draft lamp of a wick-carrying sleeve surrounding
the central draft air tube, made in longitudinal sections, and connected together by
a hinge joint on opposite sides, a wick-operating offset handle fastened by a hinge
joint at its lower end to said wick-carrying sleeve, and a perforated thimble or cone
burner surmounting the central draft air tube at its upper end, substantially as
shown and described.
4. In a central draft lamp, the combination of a wick-carrying sleeve made in
two or more longitudinal sections hinged together by a joint on opposite sides, an
off-set handle, and a hinge joint connecting said off-set handle at its lower end to one
of the longitudinal sections of said wick-carrying sleeve, substantially as described.
