The principal object of my improved apparatus be described further along in the present specifi
In the assembled view shown at Fig. 1, it is to
be assumed that the apparatus is to be added to 10
conventional oil range burners in combination
is the combination of a rotatable Vdamper operated
" from the outside _of the range in which th'e oil
3" burner is used and which makes it possible to di-4
rect the heat .either over the oven~ or against the
top of the rangeeither in a vertical direction or at
with `combination oil and gas ranges in which II
illustrates a conventional perforatedsleeve to
an angle thereby concentrating heat Íat desired
gether with the base I2 and support I3.
Another Objectis an improved means of mount
ing the apparatus and adjusting the same for >var
ious positions;
Still another object‘is quick demountable means
for removing the apparatus with particular refer-4
ence to the damper portion, andother objects

My present improved apparatus is designed to
meet several conditions as will beexplained. As
shown in Fig. 1,w~the range I0, Ashown in dot-and
#70 dash lines, vmay be a combination gas and oil -in
stallation in which separate independently manu
factured oil burners areinstalled and whichdo
not come equipped „with my apparatus. In an
other instance :the range I0 may-be manufactured
5‘5 together with `vanoil Lburnerhin »which is incorpo
such an installation, I mount my improved ap- l5
paratus I4 over the sleeve II as a separate unit
and support it in an adjustable manner on the in
side surface of the range Ivß, as shown in Fig. 1.
The apparatus p_roper comprises a top member I5, N) O
better shown in Figs. 1 to 4 inclusive, which is
further vprbvided with an opening I6 and a `de-pending flange Il, the `front side of which is open,
as shown at I8 in the bottom plan view illustrated
at Fig. 3. On lthe top of the top member I5 I have
located boss members I9 and 2B which form open 25
bearings in which is journalled a damper disc
rnember‘ZI on trunnions 22 and 23. On the outer
end‘of the trunnion 22 I have provided a square
end 24 over which is fitted a hollow square tube
25. At Fig. 7 I have shown a regulator member 30
comprising _a shaft 26 squared at 2l and shoul
dered at ¿2_8` and having an indicating handle
member v29.- preferably positioned so that its
majoraxislìes in the same plane as the diagonal
corners of the squared end 21. In Fig..4, it will be 35
noted that'the squared end of ,the trunnion 22 is
located so that its diagonal corners are at right
angles _to the iiat sides of thedamper 2l such that
the indicating handle member `29, when properly
assembled, will properly indicate .the position of 4U
the damper >from lthe koutside of the range, as
shown in Fig. 1. Preferably the unit shown at Fig.
r1 is cast _in onepiece but it _may _be assembled from
several pieces if desired. When the member
shown at Fig. 7 is assembled„it is passed through 45
the iront of the >range IILas shown at Figs. `1 and
2„ and a compression spring-26 is placed onthein
side. A retaining washer 211 ~is then placedon the
inner squared end 25 against the spring 261 and
is held inlplace by means of a Cotter-pin _281 which Ui O
passes through the pin hole 291 in the member
21. The squared member 25 4may be pinned at 30
>to the trunnion'memberM through the pinhole 3|
or. it `may be -`fixed to the member 2'I,k as the case
may be.

It will thus be apparent that when the unit
shown at Fig. ’7 is pulled out from the outside of
the range l0 it will be disengaged from the trun
nion 22 and the damper member 2| may then be
readily lifted up and off of the top I5. An eye
member 32 is attached to the damper member 2|
to facilitate its removal.
Attached to the under side of the top member
I5 is a semi-circular sleeve member 33, the side
facing the oven 34 of the range I0 being open.
The sleeve 33 is held in place in any suitable
open end I8 of the top member I5 in much the
same manner as disclosed in my previously re
ferred to application. If it is desired to divert
heat from the oven to the top of the range the
damper 2| may be turned from the outside of the
range and tilted to any angle desired thereby al
lowing the heat to be directly applied to the top
of the range. The maximum position is natural
ly when the damper is in a vertical direction.
Inasrnuch as practically all range oil burners
are installed in pairs it will be apparent
manner, as by the pin 35 located in the bottom side that with my dampers 2| set at opposite angles
of the top I5. This pin is- located slightly to the ' I am able to concentrate or direct the heat

bound against the recess 36 in'the back of the 0fV the range thereby greatly intensifying the

sending some of it to the oven and some to the
The means for supporting the unit I4 in place top of therange, as desired. With such an ar
20 is illustrated in Figs. 5 and 6. In Fig. 6 I have
rangement the necessity of removing vthe covers
shown bracket members 31 having open foot por
tions through which bolts may pass to fasten the
said brackets to the front of the range I0, as
shown at Fig. l. These brackets are reversible.
On the top of these brackets I have positioned a
horizontal slotted bar member 38 which may be
bolted to the free legs of the brackets 31. With
such an arrangement it will readily be seen that
I may vary the elevation of the bar 38 together
30 with the brackets 31 and vat the same time I may
vary the position of‘ the bar 38 outwardly or in
wardly with respect >to the front of the range l0.
At Fig. 5 I have shown a perspective view of an
other bracket 39; the rear end of which is pro
vided with a right-angled wedge member 45|Y
which is adapted to ñt in the slot 42 in the bar
38. On the front end of the member 39 I have
provided a vertical side member 43, the lower
portion of which is slightly curved. The top p0r
tion of the member 43 is adapted to be inserted
in the recessed portion 36 of the top member I5
between the sleeve 33 and the back of the flange
I'I, better shown at Figs. 3 and 4. The bottom
portion of the member 43 bears against the lower
portion of the sleeve 33 and supports it together
with the top I5, as shown in Fig. 1. In Vthe po
sition shown in Fig. 1, the sleeve 33 is positioned
closely around the conventional perforated sleeve
|I, the top edge of which is slightly higher than
the bottom edge of they sleeve 33.
It will thus be seen that in an installation of
the type shown in Fig. 1, my improvedappara
tus may be positioned `and adjusted in any de
sired relation to the range burner within reason
able limits. In other words, it may be easily and
quickly adjusted to its proper location with a
minimum of effort andrtrouble.
shown in my prior application is avoided and
much greater flexibility of heat control is had
making it possible to obtain concentrated heat on
top of the range and at the same time getting
suiiicient heat delivered to the oven for baking. 25
Another important feature of the top member
I5 which should not be overlooked is the fact
that the opening I6 in the top is smaller than the
outer sleeve II and the result obtained is that
the heat Vis slightly retarded due to the fact that 30
it is slightly converged toward the center of the
burner and thereby slowed Yup to the effect that
the base I2 becomes hotter and the gases are
more completely burned greatly increasing the
eiiiciency of the burner, the net-result of which
is more heat with less oil consumption than is
possible where the sleeve I I Vis not in combination
with the unit I4. -'I‘he heat trapped temporarily
under the flanged top member I5 reiiects against
the base or bowl of the burner causing more per
Vfect combustion of the gases generated thereon.
.When the', above apparatus is used in certain
types ’of older coal ranges where the under side
of the top of the range is lower it may be desir
able to remove the dampers from the` top I5 when
all the heat is desired to be directed or diverted
under the top of the range owing to the fact that
insufficient clearance is present to allow the
damper to be'turned to a full open position, For
such installations I have provided the eye mem
ber 32 so that a hook may be inserted therein
and the damper 2| removed entirely. When such
removal is made it is only necessary to pull out
the member illustrated at Fig. '7 and lift the
damper 2| off of the top I5 replacing it when it
is desired to use the oven.
Even under such in
stallations the damper may be rotated part way
In installations in which the oil burner is built open and when two units are opposed or con->
into the range and properly adjusted at the fac
verged toward each other suflicient heat will be
tory, the sleeve 33 and the conventional sleeve present on the top of the range for the greater
|I may be made in onevpiece, as in Fig. 8. In' portion of the time. l
such construction the upper portion 33a is open
in the same manner as shown in Figs. 1 and
3 in the drawing, the open side being above
the upper perforated portion of the sleeve IIa
adjacent the oveny side of the range. With such
construction the brackets and bar member
shown inV Figs. 5 and 6 will be eliminated but the
damper and apparatus shown in Figs. 2'and` 'l
will be used.
In operation, the damper 2| performs a very
essential and important function. When the
damper is positioned as shown at Figs. 1 "and 2
in the drawingrthe maximum heat is Vdirected out
75 over the top of the oven 34 passing under'rthe
Itvwill thus `be seen that while I have shown

is to be understood that I may vary the con
struction in proportion within wide limits with
