OVEN FLUE OUTLET Filed April 5. 1930 I Patented Oct. 20, 1931 PATENT OFFICE UNITED STATES LESTER s., murmur, or an. LOUIS, mssouanassienoa romnalcan 'srovn conrm, or sun. Louis, mssoum. A ooaronarrqn or new many I l ovmr Fl t E 6am Application filed April 8,

This invention relates to improvements in oven flue outlets, particularly or use in con nection with gas ranges and might be termed a fluev gas deflector, as the purpose of the 3 device is to deflect the flue gases-which escape from the oven in a forwardly direct on to protect the kitchen walls from being marred by these gases where the flue outlet of the oven is not connected with a flue pipe. At the present time, it is quite a common practice to allow the flue gases from the oven of the gas range to escape into the kitchen rather tl'ian to connect the oven outlet with a flue pipe leadin "to a point outside of the house, and it has een the common practlce to let these flue gases escape in a vertical direction with the result that the kitchen walls become stained andom'arred from the passage of the oven gases along the surface of the walls.

The present invention has been conceived to overcome this objection. which is-present in the flue constructionsc'ommonly used and the present invention has "also been conceived so as to provide a flue gas outlet or deflector which is more pleasing in appearance than those now known and in use and, additionally, to rovi de a device which is readily and quic 1y attachableto the oven of the range in a simple manner.

Accordingly, the primary, object of the invention is the provision of a novel oven flue outlet or oven flue gas deflector.

A further object of the inventionv is the scribed which is pleasing in appearance.

A still further object of the invention is the provision of a device of the character'- provision of a device of. the character de-.

attachable mo. an to; 441,290.

in conjunction with the accompanying drawm s.

n the drawings: Figure 1 is a view in front elevation of a .range oven having attached thereto the improved oven outlet flue.

Figure 2 is a fragmentary vertical sectional view through the upper rear end of a range oven showing the attachment of the improved flue outlet. v

In its preferred form, the outlet flue or deflector is made in three pieces, two of which are sheet-metal stampings, while one is a castq ing. The sheet metal stampings are indicated at A and B, and the casting at C.

The oven as an entiretyisv designated at D. The oven shown is one of more-or-less conventional type in that the oven top l'has at its rear edge a depending flange 2, which tele-' scopes or receives behind it the upper edge 1) of the'rear oven wall 4, which wall is pro-,

vided with an outlet opening 5 in connection with the flue arrangement 6 of the'interior of the oven.

The stamping A is adished oval shaped member-having at its open'side a peripheral outwardly bent flange 7, which flange at the bottom of the, member is provided with an;

elongated depressed or .dished extension '8 .having therein an opening 9.

The stamping or memberB, at its" bottom,

presents an elongated straight line flatportion 10. Centrally of the member it is provided with a depressed portion 11 forming the vperipheral edge of an opening 12, with the result that the depressed portion. 11 "is surrounded by a U-shaped bulge 13.

c The casting-C is of circular form and of a diameter to properly fit within the depressed portion 11 of the member B, and as it; is pro- "videdlwith a plurality of openings 14, this casting constitutes a grid for the enlarged opening 12 of the ring B. Centrally of its rear face, the casting or grid 0 is provided with a lug 15, having an interiorly screwthreaded opening 16.

The ring B and the grid C are secured to the upper end of the oval dished shaped member A, by means of a long bolt 17, which passes through the rear of the back wall 18. of the member A and is threaded into the lug 15, of the grid. The rear wall 18 of the member A is formed with the de ression 19 to receive the head 20 of the securing bolt 17.

Intermediate of its length, the flange 7 of the deflector member A is provided with two tongues 21, which are ofi'set from the flange and extend in vertical parallel relation in respect thereto.-

The member A is attached to the oven by inserting the tongues 21 upwardly between the depending flange 2 of the oven top and the upper edge 3 of the rear wall of the oven am then securing the bottom of the member A to the re'arwall of the oven by means of a bolt 22 and the nut 23. It will be seen that the bolt 22 always remains in place by reason of thelock nut 24, which look nut is received within the dished portion of the flange extension 8.

lVith the parts secured and positioned as above described, it will be seen that the bulged portion 13, rests upon the oven top at its rear edge with the elongated portion 10 of the ring 13 paralleling and engaging'the outer surface of the depending flange 2 of the oven top, thus aiding in the support of the entire device.

VVit-h the device secured in-the manner described, the flue outlet5 in the rear wall of the oven is in communication with the interior of the dished oval shaped deflector and conveyor A, and the conve or A is closed throughout thegreater portion of its length by the rear Wall of the oven to form in conjunction therewith a pipe.

It will be further seen that as the flue gases pass up the conve or, they will be discharged forwardly throug the grid 0 enings 14, over the, oven top, and thus directe away from the walls of the kitchen.

The device is very simple and cheap of construction and is made in only three parts and furthermore, it is quickl and easily assembled and attached to t e oven range.

When the deflector is in place, it is held securely against displacement and provides an eflicient oven flue and oven flue gas defleet-or. By reason of the bulge 13, the stam ing or annular ring B is supported throng out its length upon the rear edge of the oven laving thus described m invention what I claim and desire to secure y Letters Patent 18:

i A range having a flue ,outlet in its rear vertical wall, of an outside flue having its inner side flat vertically and fitting against the said rear vertical wall of-the range subsignature.
