Improvements in Oil Burners and in their Application to Cooking-
stoves and to Heating Railway Cars.
We, HENRY SCHREINER, of 1639 Poplar Street, in the City of Philadelphia, in the
County of Philadelphia, and State of Pennsylvania, United States of America,
Physician, and GEORGE WASHINGTON WRIGHT, of Corner of 17th and Poplar Streets,
in the City of Philadelphia, in the County of Philadelphia, and State of Pennsylvania,
United States of America, Merchant, do hereby declare the nature of this invention
for a NEW AND IMPROVED SAFETY OIL BURNER AND CAR-HEATER, 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 improvements in Safety Oil Burners and Car-Heaters
and consists in the construction and combination of parts hereinafter set forth and
claimed.
The accompanying drawings illustrate the invention.
Figure 1 is a vertical section of the improved car-heater. Figure 2 is a plan view
of the burner used therein. Figure 3 is a central vertical section of Fig. 2.
Figure 4 is an enlarged view of the valve-controlling device. Figure 5 is an edge
view of the weighted wheel and dog. Figure 6 is a sectional view of the portion of
cook stove or range with a burner of another form applied thereto. Figure 7 is
a plan view of the burner shown in Fig. 6. Figure is a plan view of an air seive
used with burner shown in Figs. 6 and 7. Figure 9 is an elevation of a draft plate
employed in the cook stove forin. A is the body of the stove of either kind above
mentioned. In such a stove is placed a burner in which oil is burned without a wick.
In the car-heater a circular pivoted and weighted burner is employed which retains a
substantially horizontal position under all ordinary movements of the car, while in the
cook or other stove no such provision is needed, and a straight burner is employed.
B is the burner trough in both forms which is preferably formed with a high back
or outer side 6 and has at suitable intervals bridges J J on which a burner pipe D¹
is supported, which is carried out through the walls of the stove and is connected
with a supply pipe D which communicates with an oil tank and is provided with a
stop cock G immediately under the tank by which the supply of oil can be shut off:
and also with a needle-valve H, at a convenient point in its length. The burne pipe
In the
is provided with openings through which the oil passes as it is being burned.
bottom of the burner trough a layer of ashes, sand or other non-combustible material
marked 6* is provided on which a few drops of oil is allowed to fall and is then
ignited in order to heat the oil in the burner pipe to a sufficient degree to cause it
to burn freely as it passes ont of the openings d. Kerosene or other oil is employed.
Foraminous air screens or seives $ are employed to regulate the draft of the
burner and aid combustion.
The parts thus far described by letter are with certain necessary modifications
common to both forms.
In the car-heater the trough B is circular and likewise the burner pipe D' and the
trough is provided with cross pieces I in which is formed a central seat where they
meet, and this seat rests upon the rounded head of a standard C which is suitably
anchored to the bottom of the car-heater. A circular weight F is swung from the
trough or from the cross picces II and serves to keep the burner in equipoise under
all ordinary conditions and movements of a railway coach.
In connection with the needle-valve H in the car-heater supply pipe, an automatic
cut-off for use in case of accident to quickly stop the flow of oil to the burner pipe is
employed. It consists in providing the stem of the needle-valve with a weighted
wheel H', which has a section of its circumference ratcheted as shown at H*.

page_text: A gravity dog K is hinged to a fixed part of the car over the wheel, having teeth
on its end which engage the ratchet teeth on wheel H', and may be operated by
hand, but to make the device entirely automatic, as required, a wedge L is provided
which may be mounted on rollers, which are sunk well into the body of the wedge so
as to bring its point near the incline on which the rollers rest and cause it to raise
the dog when pushed forward, and when any dangerous jar or concussion takes place
it will shoot under the notch K' in the dog and raise it out of contact with the ratchets
on the wheel, which will be turned by the weight and close the valve at once.
The
valve is placed as near the burner as can be done so that very little oil will be in the
pipe below it when closed, and the fire will go out almost instantaneously.
If the trip mechanism should be moved by a jar which does not result in disaster,
the valve can be at once reopened and the cut-off reset, and the fire, if out, relighted
at once.
A spring may be employed in lieu of the weight upon the wheel.
In the circular burner the foraminous plates S are segmental in form and cover the
entire space surrounded by the trough, and rest upon its lower inside wall of side.
In the cook stove burner ears are provided which rest in seats in the walls of
the stove and the foraminous plate S is divided into straight sections which lie
between the bridges J J and are connected to a back which rests upon projecting
portions of said bridges.
The back lies close to the rear of the fire box and a draft plate T is employed to
cover the space from the front of the grate bars up through the foraminous plate
to the burner pipe. In this form of burner the same form of supply pipe, oil tank
and valve may be employed as in the car-heater, but it is not necessary to have any
automatic cut-off. Starting the burner in lighting the fire is also accomplished in
the same manner.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
1. In a car-heater the combination of a standard, a circular burner pivoted thereon
and a circular weight surrounding said standard and suspended from said burner, as
set forth.
2. A burner for burning oil consisting of a suitable support, a trough pivoted upon
said support and having a high outer side, a series of segmental foraminous plates laid
over the trough upon its lower inner side, and a burner pipe D' placed over the
foraminous plates inside the higher outer wall of the burner, as set forth.
3. The combination of a circular trough having a layer of ashes or sand, bridges or
partitions at suitable intervals, a pivot on which trough is supported and a circular
burner pipe supported on the bridges in the trough, as set forth.
4. The combination of a circular burner having a trough as described, a burner
pipe supported upon said trough, a supply pipe connected to the burner pipe and a
pivot or support on which the whole is pivoted, as set forth.
5. The combination with a suitable support, of a circular burner pivoted thereupon
and a circular weight suspended from the burner, as set forth.
6. The combination with a heater and supply pipe of a needle-valve in said supply
pipe, a weighted wheel on the stem of the needle-valve having ratchet teeth on its
rim, a gravity dog engaging said teeth and a wedge for automatically raising said
dog, as set forth.
7. The combination with the feed pipe of an oil heater, of a needle-valve, a weighted
wheel on the stem of said valve having ratchet teeth over a portion of its circum-
ference, a hinged gravity-dog having teeth for engagement with the ratchet teeth and
a wedge mounted on rollers for operating the dog, as set forth.
8. In a stove, the combination of a burner-trough having an elevated back, bridges
placed therein, a foraminous plate and burner pipe supported on the bridges above
the foraminous plates and an imperforate plate, T, resting upon the front of the grate
at its lower end and against the foraminous plate at the top, as set forth.

page_text: 9. In a stove the combination of a burner-trough having ears resting in the walls
of the stove, bridges in said trough, a foraminous plate supported on the trough and
bridges, and a burner pipe supported on the bridges above the foraminous plate, as
set forth.
