1, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co. Patent Agents, of
Southampton Buildings in the County of Middlesex, 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 :-
The improvement consists first, in wick-adjusting mechanism consisting essentially in
a ring which surrounds a wick and may be secured thereto in any desired manner or
the ring may be roughened on its interior surface or it may have inwardly
extending teeth to engage in the wick material. To this wick ring I attach an arm
which extends upward through an opening in the upper wall of the oil fount and to
the outer end of this upwardly extending arm I attach an operating rod which
preferably extends downward through a tubular way provided within the oil fount
and opening through the upper and lower walls thereof. The operating rod may, if
desired, extend around the outer side of the oil fount but in either event it should
extend downward to a point within reach of a person standing on the floor so that
the wick may be adjusted therefrom when the lamp is suspended.
The improvement consists further in the harp or hanger for the lamp adapted to
be suspended by an eye formed in its upper portion, from a ceiling or other overhead
support and the lower ends of the harp are secured to the lamp body by means of pin
and socket connections, which may be arranged by providing upwardly turned pins
on the harp to engage sockets projected from the lamp, or the order may be reversed,
or the ends may be secured to suitable clips in any desired manner.
The clips or
connections are also secured to the respective ends of a hand piece of wire bowed
beneath the lamp to form a handle by means of which the lamp may be drawn
downward when suspended by a counterbalanced chain or similar mechanism. The
hand piece serves a further purpose as its ends extend upward through the clips
forming pins to engage in suitable sockets projected laterally from the lamp body.

page_text: The improvement further consists in providing a suspending mechanism for the
lamp shade which is essentially a ring of metal or other suitable material adapted to
surround a portion of the shade and having diametrically opposite hooks or catches
for engaging in sockets secured to the harp. The ring surrounding the shade may
be secured thereto by means of thumb screws passing through threaded openings
and impinging upon the shade beneath a bead usually provided near the top of
a shade.
In the accompanying drawing Figure 1 is a side elevation of a lamp embodying
the several improvements, several parts being shown in section. Figure 2 is a
sectional view of a lamp body showing the wick adjusting mechanism. Figure 3 is
an inverted plan of the parts shown in Figure 1, the shade being omitted, and
Figure 4 is a plan view of the shade holding ring partly in section, and showing a
portion of the lamp support. Similar letters of reference designate corresponding
parts in the several figures.
The body, A, of the lamp is provided with a central vertical tube, A', which serves
as an air flue to convey air to the centre of the flame and serves also as a support or
tube for the wick, B. A ring, B', of metal surrounds the wick and may be of any
desired length, but I prefer to make it about one half the length of the tube A', as it
is designed in the example shown, to engage the wick by friction, but, as stated, the
inner surface of the ring may be roughened or provided with engaging teeth. The
arm, C, consists essentially of two portions a a', which may be at right angles to
each other, and the portion a may engage loosely within a vertically disposed strap, b,
secured to the ring B', so that said ring may be disengaged by simply rotating it and
the wick. The portion a' of the arm, extends upward through an opening, 6, in the
top wall of the oil fount and a guide, c, may be provided to prevent lateral play of
the arm. The inwardly turned end, e, of the operating rod, D, is provided with an
opening to engage the reduced upper end of the portion, a¹, of the arm C, and it
may be secured thereon by means of a nut, d, engaging the threaded portion of the
reduced end of the portion a', as shown, or the operating rod may be otherwise
secured to the arm.
The operating rod extends downward through a tubular guideway, D', which is
secured to and opens through the top and bottom walls of the lamp body or oil fount,
and an extended collar, d, may be secured to the lamp body at the lower opening of
the tube, D', and have a flange, e, thereon providing a finger hold which is essential
to facilitate the adjustment of the wick which is accomplished by pushing upward or
pulling downward the operating rod in the guideway tube, which in turn, operates
vertically the arm C, and consequently the ring B', and wick.
The harp or hanger. E, consists of suitable wire bent centrally to form the two
diverging sides ff, or the sides may be separate wires suitably coupled together at their
upper ends, to which coupling may be attached a suspending ring, 9, and a hook, g¹,
from which the smoke bell is hung. The lower portions of the sides ff are bowed
outward and inward and have their lower ends substantially vertical and secured by
solder, or otherwise, to clips, F, which extend inward and are rigidly fastened to the
hand piece, F¹, which is semicircular and bowed beneath the lamp for convenience in
raising and lowering the lamp, as before stated. The ends of the hand piece project
above the clips, as shown, to engage within sockets, h', in the lugs, h, extending
laterally from the sides of the lamp body, or the said socket lugs may be secured to
a ring or band which loosely surrounds the lamp body. In the first construction the
lamp and socket lugs may be removed bodily from the projected ends of the hand-
piece and in the latter event the lamp may be lifted from the band, leaving the band
and lugs in engagement with the hand piece.
G is a shade of the usual formation, having the beaded upper or neck portion G¹.
Surrounding this neck portion is a metallic band, H, having at diametrically opposite
sides, catches, i, which, in the example shown, are secured to the band in any suitable
manner and have looked portions, i, to engage within sockets, I, which are rigidly
secured to the opposite portions of the harp. The band, H, is designed to be
removably secured to the neck portion of the shade and we find it convenient for the

page_text: purpose to provide thumb-screws, j, which extend through threaded openings in
the band and impinge lightly against the shade neck beneath one of its beads.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondents I declare that what I claim is :-
1. A wick adjusting mechanism consisting of a ring adapted to surround the wick,
an arm extending from said ring through the upper wall of the oil fount, and an
operating rod secured to said arm and extended downward below the lamp body,
substantially as specified.
2. A wick adjusting mechanism consisting of a ring surrounding the wick, an
arm detachably secured to the ring and extended upward through the wall of the
oil fount an operating rod secured to the upper end of the arm and extended
downward through a tubular guideway in the lamp body, and a collar at the lower
end of the tubular guideway, substantially as specified.
3. A lamp hanger consisting of the wire forming the harp, the bowed hand piece
secured to the lower ends of the harp portion by means of clips, and the socket lugs
extended laterally from the lamp body to engage the extended ends of the hand piece
substantially as specified.
4. A lamp hanger consisting of the harp having the substantially vertical lower
ends, the clips secured thereto, the hand piece bowed beneath the lamp and secured
to the clips, the band or ring surrounding the lamp body and having the socket lugs
adapted to engage the projected ends of the hand piece, substantially as specified.
5. A shade suspending mechanism consisting of a band adapted to surround the
shade, and having fastenings, catches secured to opposite sides of the band and sockets
on the harp for engaging the catches, substantially as specified.
6. The combination with a lamp frame or harp having opposite side portions, of a
lamp removably connected thereto by means of pin and socket connections, substan-
tially as specified.
7. The combination of a lamp frame or hanger, having opposite side portions
provided with pins or projections, and a lamp provided with projections constructed
to engage said pins or projections of the harp, substantially as specified.
