I HOWARD WILKINS WRIGHT of the firm of Wright and Butler Limited of New
John Street West Birmingham in the County of Warwick, Lamp Manufacturer, do
hereby declare the nature of this invention to be as follows:-
1-
Heretofore the reservoirs or tanks of oil stoves have been made up of two or
more parts, joined together by soldering; and in consequence of the said reservoir or
tank, being moved into and out of position, by a sliding motion, the bottom which
comes into immediate contact with the base of the lamp, becomes worn, and leakage
ensues.
The object of my invention, is to obviate this defect, by making the reservoirs, or
what are commonly called the founts, seamless; and further, in means for preventing
the said bottoms from coming into immediate contact with its supporting surface.
The means employed, consists in elevating the reservoir or fount, upon two opposite
sides, of a depth greater than the reservoir as aforesaid.
In carrying out my invention, I proceed as follows.
I take a blank of sheet metal, and by means of dies and pressure, I raise it into a
trough or long vessel, with inwardly tapering sides, and with a flange running along
its top outer edge.
To the underside of the opposite flanges as aforesaid, side plates or rests aro
respectively secured and which plates or sides, are of a greater depth than the
reservoir fount; so that the bottom thereof is elevated above the plane, upon which
the sides rest; and when the reservoir fount or tank is moved into and out of position,
by a sliding motion, all wear takes place upon the bottom edge of the supporting plate
or sides.
Thus, the reservoir, fount or tank, is made seamless, or from one piece of metal, and

page_text: elevated above the plane upon which its rests, by supports or sides, which may be made
in one piece with the vessel, or attached separately by soldering.
The burner, and other adjuncts, in connection with the reservoir, are fitted upon an
open, or closed top as aforesaid.

I, HOWARD WILKINS WRIGHT of the firm of Wright and Butler Limited of New
John Street West, Birmingham in the County of Warwick, Lamp Manufacturer 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 reservoirs (or tanks commonly called founts) of oil stoves,, have heretofore been
constructed or made up of two or more parts, connected or joined together, by
soldering or otherwise; and in consequence of the said tanks having to be moved into
and out of position; by a sliding motion, their bottoms become worn, and leakage
ensues.
The object of my present invention, is to remedy this defect, by making the bottoms
or lower parts of the said founts seamless, or seamless in respect of the parts, which
come into contact with the supporting surfaces, upon which they slide.
.
The means thus employed consists in elevating the bottom underside of the said fount,
from the contact surface, and also in making the lower part of the fount, from a single
blank of sheet metal, raised and fashioned into a dish-like receptacle, with flanged
edges, of which the latter slide upon ledge supports, secured to the opposite inside
walls of a single lamp stove.
In making the founi, I take a blank of thin sheet metal, and by means of dies and
pressure, raise or fashion it into a trough or dish-shaped vessel, preferably longer in
one direction, than in the other, and with the top outer edging turned at right angles
into a flange which forms the tank support.

page_text: The seamless dish-shaped vessel as aforesaid, which constitutes the lower part of the
fount, is enclosed by a covering or top, whose outer edge is turned over the boundary
flange of the other part.
The inside walls of the stove, have ledge like supports, upon which the tank is elevated
and slides.
Figure 1 of the accompanying drawings, represents in front elevation, a double
lamp-oil stove, provided with improvements made according to my invention, and the
lower part of the fount thereof, made seamless, or from one piece of metal. Figure 2
is an end elevation of the same, with the lower part in section, showing one of the tank
shelves or supports. Figure 3 represents the lower portion of the stove in section,
upon an enlarged scale, and also one side or part of a fount resting upon it.
Figure 4 is a complete vertical section of the fount, and figure 5 is a plan of the same,
with one side broken away.
The same letters of reference indicate corresponding parts in figures 1 to 5.
a is the body of the oil stove, b is the bottom thereof, c are the sides or enclosing
walls, to which narrow ledges, or tank supports d, are secured to the insides thereof, as
best seen in figures 1 and 3. These ledges or supports are directed inwardly, and
are elevated from the bottom b, to an extent greater than the depth of the fount e,
whose bottom part e is made seamless. This said fount lower part, which is fashioned
from a single blank of sheet metal, has boundary flanges e, over or upon which, the
enclosing covering e of the fount is secured by soldering or turning over. Thus, it
will be seen that the fount is elevated above the bottom of the oil stove, by two of its
opposite flanges, in its longer direction, resting upon the tops of the ledges, which
are elevated at a plane higher than the depth of the fount.
The ledges or supports d, have at their front sides, leads or incline planes d², up
which the flanges of the fount slide, in elevating and placing them in position. The
said founts have the usual burner and other accessory parts f, which constitute no
part of my invention.
To increase the wear on the undersides of the flanges of the founts, I may thicken
the metal at those parts, by soldering extra metal strips thereto, or bending the
boundary edging of the enclosing cover of the fount upon itself, as shown at
figure 6.
Figure 7 represents a double oil lamp stove, provided with two independent founts
instead of one, as in the preceding arrangement.
a is the stove, is the bottom thereof, are two opposite ledges, carried upon the
inside faces of the sides c. e are founts, with flanged edges e³, which rost and slide
upon the ledge supports d, d², whereby the bottoms of the founts are elevated from the
bottom of the stove.
The ledge supports d² are made from an upright strip of metal, secured at its lower
end to the stove, while its upper end is made crutch or T like.
Figure S represents another form of stove, in which the fount constitutes the base
or support thereof, which is made in accordance with my invention, as previously
described, although the bottom of the said fount, or tank (which is seamless at its lower
part) docs come into immediate contact with the object upon which it rests.
Figure 9 represents another form of elevated fount, which is mounted upon box
like sides, thus dispensing with the ledge supports secured to the insides of the stove
walls.
e is the tank or fount, e the flanged edges, e the enclosing top, and e³ box like
sides, of a depth greater than that of the fount or tank, and upon which the said tank
slides, and is elevated above the supporting surface, upon which it rests.
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.
First. Making the lower parts of the oil founts, tanks or reservoirs of oil stoves,
seamless, or without joints, substantially as described and set forth in the several figures
of the drawings.

page_text: Secondly. An oil fount or tank, consisting of a seamless lower part e, e³, and a top
covering e, with the boundary edge of one, folded over, or soldered to the boundary
edge, or the flanged boundary edge of the other, as set forth in the several figures of
the drawings.
Thirdly Supporting and sliding oil founts or tanks, or the flanged edges thereof,
upon elevated ledges or supports, whereby the undersides of the said founts or tanks
are raised from the bottom or floor of the stove, substantially as and for the purpose as
set forth in figures 1, 2, 3 and 7.
Lastly Elevating the undersides of oil founts or tanks from the bottom or floor
upon which they rest, by sides e, which are of a depth greater than that of the oil tank
supported, substantially as set forth in figure 9.
