' Applicationjled January 17, 11921. Serial No.71:37,.,868.V

To all/whom it may concern:

Be it known that I, EUGENE L. BAKER, a

'i lcitizen' of the `United States, residin at Taunton, in the county ofk BristolI and tate of Massachusetts, have invented a new and useful Stove Oven, of which th'efollowing is ay specification. a

This invention aims to provide a foldable deflector for use in ay stove in which either ygas or solid Afuel is employed, the deflector ,forming means for raising and lowering a member which closes the air inlet, saidmember being so constructed that 1t cannot serve as la deflector, and there being no deflection uof the heat, in the 'absence of lthe foldable l and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention` shown can-be made without departing from the spirit of the invention.

yIn the accompanying drawings I Figure 1 shows in vertical section, astove oven equipped with thedevice forming the subject matter of this application, the deflector being lowered; Figure` 2 is a` view similar to Figure 1,the1deector being raised and folded; and Figure 3`is"'asection on the line 3-3 of Figure 1. f.

The stove in which the invention is embodied, may be constructed variously. Therefore, the stove structure will be described somewhat briey,those parts only being alluded to, which have some function in connection with the device forming the subject matter of this application.

In the drawings there is shown a stove oven defined by walls 1 and 2 disposed opposite to each other, and by walls 3 and 4, likewise disposed opposite to each other, the wall 4 having an offset portion 5. The top of the oven is shown at 6 and the bottom thereof appears at 7. Walls 8 cooperate with the bottom 7 and constitute a part of an air inlet 9. The oven has an outlet for Specification of Letters lfatent.y

The part 28 of the deflectorcarriesgdepend ing ears 31 pivoted at 32 to the walls land 2. W'hen the deflector 26 is opened, as shown in Figure 1, the 'deflector is supported on j,

brackets 33y projecting from the Vwalls 1 and 2- Levers 34 are fulcrumed, intermediate their ends, as indicated at 35,' on 'the walls 1 and 2, the. inner end of each lever being upwardly extended as indicated at 36, the

ends 36 of the levers being adapted to co" operate with the part 28 of the foldable` deflector 26. In the outer ends of the levers l 34, seats 37 are fashioned, the samebeing adapted to receive hangers 38 on a member 39,-whichmay be a burner, said member bej ing so shaped that when itis lowered, it will seat in the upper end of the air inlet 9 and i .shownin Figure 3. ylonger is engaged by the part 28 of the de 'is accomplished solely by the member 26,

when the member 26 is lowered, as shown in F ig. 1, and the burner 39 has no function as a defiecting means. When coal, Wood or any other solid fuel is used, the parts are arranged as shown in Figure 2.` Then, the

member 39 is seated in the upper end of the air inlet 9. The parts 27 and 28 of the deflector are folded together on the hinges 29, and thevdeflector is swung rearwardly on the pivot elements 32, into the offset portion 5 ofthe wall 4. The part 28 of the de- 'fleetor engages the finger 21 of the damper and causes the leaf 19 to close the opening 20,'the leaf 1S closing the opening 15.

i When gaseous fuel is to be used, the deiiector 26 is opened and swung downwardly, into the position shown vin Figure 1. Under such circumstances, the ends 86 of the levers 34 are engaged by the part 28 of the bafiiefand the'forward ends of the levers are raised, the member 39 being elevated out of the upper end of the air inlet 9. hen the member 39 israised, the flange 41 on the part 40 engages beneath the sleeve 24, as Since the finger 21 no flector 26, the finger swings downwardly, moving the leaf 19 away from the opening 15. There is, therefore, no appreciable drag .on the heated air within the oven, the

draft being cut down because air can enter through the opening 20. At the same time, since the opening 15. is uncovered, the products of combustion may pass away, without any appreciable suction.

Having thus described the invention, what is claimed is 1. in a device of the class described, an oven having an air inlet in its bottom; a member forming a closure for the inlet and rendering the bottom continuous; means for lifting said member to open the inlet; and a deflector mounted to swing in the oven over and away from said member, the defiector engaging and actuating said means when the deflector is swung over saidmember. y' f 2. A device ofthe class described, constructed as set forth in claim 1 and further characterized by the fact that said member is a burner.

3. A device of the class described, constructed as set forth in claim 1 and further characterized by the fact that the means rfor lifting said member consists of a lever, said member being carried by one end of the lever, the deiector engaging the other end of the lever, and the lever being fulcrumed intermediate its ends.

4. A. device of the class described, constructed as set forth in claim 1 and further characterized by the fact that the oven has an outlet and a check-draft opening communication therewith; a damper controlling the outlet and a damper controlling the check draft opening, the dampers being connected for simultaneous movement, the dampers opening automatically when the deflector -is disposed over said member, the damper being provided with a iinger disposed inthe pathof the deflector,l whereby when the deflector is-swung away from said member, the dampers will be closed bythe deflector.`

` in testimony that I claim the foregoing as my own, I have hereto affixed my signature i:

in the presence of two witnesses.
