Improvements in the Mode of and Means for Feeding Oil and
similar Fluids to and Burning the same in Lamps, Stoves, and
Furnaces.
We, DANIEL MOORE, and FRANK SLOCUM MOORE, Mechanical Engineers, both
residing at 436, Gates Avenue, in the City of Brooklyn, and County of Kings, in the
State of New York, one of the United States of America, do hereby declare the nature
of the said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
The invention comprises a method of feeding the oil through water to the place of
burning, and mechanism for producing a safe and steady feed for the oil or other fluid
to the place of burning.
Fig. 1, is a section of the oil feeding and combustion device applied to a boiler
furnace.
Fig. 2, represents a central section of a stove with combustion apparatus.
Fig. 3, illustrates the mechanism of a lamp.
Figs. 4, and, 5, illustrate a student lamp and its details.
The numeral, 1, indicates a steain or other boiler; 2, is a reservoir for water beneath
the boiler. There may be air pipes, 3, passing through the water reservoir, or arranged
in other manner to bring air to the place of combustion, from a blower or other source
of air supply.
A pipe, 4, conveys oil or other combustible fluid lighter than water, from any
elevated storage tank, to a nozzle, 5, inside the water reservoir, 2., The nozzle, 5,
delivers the oil in globules, 6, 6, which rise up through the water to a plate or sheet, 7,
of fire clay, asbestos or other absorbent material, and the oil is ignited and burned
upon or in such material.
The water supply in reservoir, 2, may be regulated through pipe, 9. By causing
the oil to break into globules before raising to the surface of the water in the reservoir,
there will always be a body of water interposed between the oil supply tank and the
point of combustion. As many nozzles, 5, may be used as is found desirable, and
when the combustion plate, 7, is properly arranged the oil may sometimes be fed in a
[ Di Q71

page_text: small stream from the nozzles, the feed being controlled by cock, 8. The oil rising
through the column of water in globules is cooled, and the supply may be regulated
with great exactness. The nozzles, 5, are preferably of such size as to pass only a
drop of oil at a time.
In fig. 2, anarrangement of feeding and combustion apparatus for an oil stove is
shown; 10, indicates the water tank into which nozzle, 11, opens. The oil feeds down
from reservoir 12, through pipe, 13, the supply being controlled by cock, 14. A
perforated diaphragm, 15, is placed over the water chamber or reservoir, 10;
this diaphragm prevents the wicks from extending down into the chamber, 10. A
wick feeding roll, 17, supports a wick which extends down into the oil chamber, 16,
above the water chamber; the flame guard, 18, directs the flame to the heating
aperture, 19, in the stove.
It will be observed that the oil in chamber, 16, is not on a level with the supply in
fuel reservoir, 12. This is due to the fact that the water in chamber, 10, is of greater
specific gravity than the fuel. When oil is permitted to flow from tank, 12, through
the water in chamber, 10, it will rise above the water until the united weight or
pressure of water in reservoir, 10, and oil chamber, 16, equals the weight or pressure
of oil in chamber, 12. Then there will be no further flow of oil until the combustion
of oil in the stove admits a further supply. There is no tendency of the water to pass
back through the small nozzle, 11.
By this arrangement, the oil supply is made automatic and uniform. As many wicks
and burners may be used as desirable and the oil or other liquid fuel in reservoir, 12,
will only be drawn upon as the fuel in chamber, 16, is consumed. The details of
construction of the stove need not be specially described; as any usual construction of
hydro-carbon burning stove may be used.
The
The lamp, a, fig. 3, has an oil reservoir, b, inclosed in the water chamber, c.
oil cannot escape when the vent, d, is closed by plug, e. This vent may be slightly
opened by pressing down the rod, f, which is connected with pivoted bar, g, to which
the plug, e, is attached.. When the vent is open oil will rise from nozzle, h, through
the wick, i, in which it is burned. An asbestos or mineral wool part, i¹, may be added
to or used instead of a wick.
The oil is fed
The student lamp, k, has an oil reservoir, l, and a water reservoir, m.
through pipe, o, to nozzle, p, whence it escapes in globules into the water. The flow
is regulated by the combustion of the oil but can be turned off by cock, q. A
perforated diaphragm, r, about at the surface of the water in reservoir, m, preserves
the wick, s, from passing down into the water. The oil surrounding the wick will rise
to a level somewhat less than that of the oil in reservoir, l, the difference being
determined by the depth of water in reservoir, m. The supply of oil to the wick will
then be determined by the consumption. No oil rising from nozzle, p, until an
amount has been consumed by the wick.
A cage, t, (shown in detail in fig. 5) made of wire, or of light perforated metal,
serves to keep the wick in place. The cage may be held in the lamp by a screw
thread or otherwise. The top of the water in reservoir, m, is preferably about
on a level with the bottom of the oil reservoir, l, and the wick tube, n, rises to a
height about on a level with the top of reservoir, 1, so that all danger of overflow is
avoided.
It will be understood that features of construction common to oil feeders and burners
well known in the art have not been described herein.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed what we claim is :-
1. The described method of feeding oil or similar fluid to the place of burning, by
passing it through water in the manner described, and absorbing it in a material
above the water in which the oil is burned.
2. The mechanism described for regulating the oil supply to a burner, said mechanism
acting to break the oil into globules and causing it to pass in globular form through a
water reservoir to the place of combustion.

page_text: 3. The mechanism for preserving the surface of a column of oil or similar fluid in
the supply chamber above the surface of that in the combustion chamber, said
mechanism consisting of reservoirs and pipes arranged substantially as described, and
a body of water arranged below the combustion chamber through which the
oil passes to said chamber.
4. The mechanism for combustion of oil and similar fluids consisting of the feeder,
the water reservoir, and the absorbent material above the water relatively arranged
substantially as described.
