This ‘invention relates to an oil burner unit

‘icalled “family” oil burning cooking and heating
‘stoves, but which is generally useful for heating

5 purposes. In devices of this character, oil is fed
from a reservoir throughv valved pipes to an oil
burner usually containingconcentric oil grooves
‘in which circular‘ band‘ wicks are placed.

10 ‘different stoves, it is‘ believed that reference to the

burner unit parts, i. e., the reservoir, burner, ‘
valves and oil feed pipes, are mounted upon a
base so that they maybe inserted into and‘ re

a unit. The base may be constructed in any suit- 10
able form and of any suitable material. As

general and representative arrangements usually
employed will serve to make the present inven‘tion more clear. In such arrangements, the stove
‘ ordinarily contains a burner chamber extending
15 from the front of the stove to its rear. Twin
‘ burners are suitably mounted in parallel or series
"between the front and rear walls of the burner
chamber. An oil pipe extends from the under
1 ‘side of each‘burn‘er forwardly to its valve adjacent

At one end of the base, supporting legs 3 are 15
provided for an oil‘ sump 4. The sump is adapted
to support at a suitable elevation‘ an inverted _
reservoir, 5.
The reservoir, which is of a well known type,

has a valved outlet 6 which is held ‘closed by‘ a 20

outlet pipe 1, up to the flow regulating valves,
while the oil feed lines are often subjected to a
degree of heat sufficient to produce gasi?cation of
oil therein. Both of these results are ‘objec30 tionable.

The principal object of this invention is to
‘avoid these objections and, more particularly,
to provide a simple, compact structure which
does not require vattachment to the stove but

above the wicks; hence, the latter function only
to facilitate the starting of the burner. By the
time the burner is hot enough to vaporize the
oil in the troughs completely, the vaporizing
chamber will be heated sufliciently to vaporize
the oil as it enters.
The burners 8 should be supported at a level
such that oil from the reservoir will cease ?owing
to the burners when the oil grooves in the burners
are half full of oil. The burners should, of course,
be properly leveled to produce a uniform depth
of oil in the grooves, and such level may be ob
tained by adjusting the level of the stove accord
ingly. The burners may be directly supported on
or secured to the base I. They preferably, how
ever, are mounted on a platev H which is adjust
ably secured to the base I through the agency
of screws l8 threaded to the base and having
means at their upper ends for holding the plate.
When so mounted, ?nal adjustments of the burn
er levels can be effected by the screws.
The sump outlet oil pipe ‘I and burner supply
oil pipe l2 are, of course, connected to each other
through regulating valves and suitable piping. In
accordance with previous practice, these valves
would be provided with short valve stems and
able openings in the front wall of the stove so
that the valves may be regulated from the ex
terior thereof.
With the arrangement thus described, it will
be appreciated that the amount of oil piping ex
posed to the heat of the burner is reduced to a
minimum. Hence, the possibility of oil being
vaporized in such pipes is likewise reduced. ‘Such
vaporization is highly undesirable because it pro
duces an uneven and “spurting" flame. In some 10
instances, the pressure of the vaporized 011 causes
it to spurt sufficiently to extinguish the ?ame.
The reduction of exposed oil piping is, of course,
accomplished by placing the valves adjacent the
reservoir while convenient access for regulating 15
the valves is maintained by providing them with
long valve stems. It will also be appreciated
that the structure herein described is very sturdy
and compact and one which can be readily in
serted within a heating chamber of .su?lclent size _
to receive it. When any parts require adjustment
or repair, such parts are, by virtueof the uni
tary and removable structure herein proposed,
readily accessible.
