UNITED STATES PATENT OFFICE 2,480,044 RANGE ovEN VENT Herbert M.v Reeves, Kankakee, Ill., assignor to Florence Stove Company, Gardner, Mass., a corporation of Massachusetts Application April 23, 1945, Serial No. 589,876

4 Claims. (Cl. 126-21) The invention relates to improvements in gas ranges and more particularly to gas ranges of the table type adapted to be installed flush with a wall or other vertical surface.

One object of the invention is to provide simple and practical means for venting the ovens of stoves of the above general character which is easy to keep clean and which is adapted to discharge the hot oven gases in a manner such as to avoid objectionable discoloration of the walls or other surfaces in the vicinity of the range.

Another object is to provide improved means for venting both the oven and the space between the range and the wall against which it is installed.

Other objects and advantages of the invention will become apparent from the following detailed description of the preferred Aembodiment illustrated in the accompanying drawing in which:

Figure 1 is a fragmentary perspective view of a gas range embodying the features of the invention.

Fig. 2 is a sectional view of the range taken in a vertical plane substantially on the center line of the vent opening for the oven.

Fig. 3 is a fragmentary perspective view of the stove top with the backguard removed to show details of the flue structure.

Fig. 4 is a sectional view taken in a horizontal plane substantially on the line -Il of Fig. 2.

While the invention is susceptible of various modifications and alternative constructions, I have shown in the drawings and will herein describe in detail the preferred embodiment, but it is to be understood that I do not thereby intend to limit the invention to the specific form disclosed, but intend to cover all modifications and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.

For purposes of illustration, the invention has been shown as embodied in a gas range of the table type having a top 5 and sides 6 terminating in a common vertical plane to adapt the stove for installation flush with a vertical surface such as a wall l. An upright splasher plate or backguard 8 is mounted at the rear of the top- 5 and arranged to lie flush against the wall 1. As shown in Fig. 2, the back of the range is closed by a back member or panel 9 spaced inwardly from 1 the rear edges of the top 5 and sides 6 so as to provide an air space of substantial depth between the range back and the wall 1 to prevent excessive heating of the latter.

The exemplary range is provided with an oven III having a top wall II spaced `from the range top 5 and a rear wall I2 spaced forwardly from the back member 9 and the intervening space is filled with insulating material I3 of any suitable character. To permit the escape of hot gases from the oven I0, alined vent openings Il and I5 are provided respectively in the back wall I2 and back member 9 of the range. As herein shown, the opening I4 is encircled by an annular flange I5 adapted to telescope into the smaller end of a. generally conical flange I1 encircling theA opening I5. The iianges serve to minimize leakage of gas into the space occupied by the insulating material I3.

In accordance with the invention, an improved ilue box 20 is arranged with respect to the other elements of the range in a novel and advantageous manner to provide for the venting of the hot gases from the oven and also the space at the rear of the stove so that the gases are effectually prevented from coming into contact with adjacent wall surfaces. For this purpose the backguard 8 is constructed in the form of a relatively shallow panel and is mounted at the extreme rear edge of the top 5 with its front face spaced substantially from the back member 9 so as to leave a gap of sufficient width to allow the flue box 20 to project through an opening 2I in the top located forwardly of the background.

In the exemplary stove, the backguard 8 comprises a iiat sheet metal plate 22 having a rearwardly turned rounded flange 23 extending around its side and top edges and a flat flange 24 along its bottom edge. The flange 24 rests on and is secured in any suitable manner to a raised ledge 25 formed along the rear edge of the top 5. The front wall of the ledge 25 is preferably filetted so as to provide a rounded corner that is easily cleaned. Provision of the ledge 25 for supporting the backguard 8 raises the joint between the parts above the plane of the top and eliminates sharp corners in which dirt might collect. An upturned flange 21 around the opening 2| is formed to merge with the ledge 25 and is similarly filetted to provide for convenient cleaning.

The ue box 29, as herein shown, is in the form of a sheet metal channel comprising a web 28 of slightly greater width than the vent opening I5 and having anges 29 at opposite sides. The flue box is adapted to be mounted at the back of the stove in registration with the opening I5 as shown in Fig. 4 and the flanges 29 are turned outwardly as at 30 for convenient attachment to the back member 9 as by spot welding. When thus mounted, the flue box in combination with the baci'; member Si defines a vertical passage of generally rectangular cross section leading upwardly from the vent opening i and through the opening 2i in the range top 5. The projecting end of the flue box is open at the front to provide for the discharge of gases therefrom. Referring to Fig. 2 of the drawings, it will be observed that the flue box is also open at its lower end for the admission of cooler air which is thus effective to dilute the hot oven gases before they are discharged from the flue box.

To avoid unnecessary enlargement of the opening 2i in the range top 5, the side anges '29 of the flue box are cut back as indicated at 3l. The narrowed portions of the flanges thus formed are arranged to project a substantial distance above the top 5 and serve to support and position a cap or hood 35 arranged to direct the vented gases outwardly and downwardly over the range top.

Provision is also made for venting the space between the range back il and the wall 'i to prevent excessive heating of the latter. To this end, the opening 2l in the range top is made slightly longer and wider than the projecting portion of the flue box so as to provide outlets 36 (Figs. 3 and 4i) at opposite sides of the box and an outlet 3l at the rear of the box. Circulation of air may thus be maintained between the range back 9 and the wall l, as the heated air is free to pass upwardly through outlets 36 and 3T as well as through the open end of the flue box.

The hood 35 is constructed and arranged so that the air rising through the openings 3B and 37 as well as the gases rising through the ue box 20 are deflected outwardly and downwardly over the range top 5. Moreover, the hood is mounted with a particular view to facilitating its removal for cleaning. To this end, the hood is constructed in the form of an elongated box-like structure of sheet metal or other suitable material open at its lower end and dimensioned to extend over the outlets 36 and 31 at the sides and back of the flue box. Preferably the hood is formed with a fiat rear wall 40 adapted to be held snugly against the face of the backguard 8 by horizontally spaced vertical ribs fil stamped in the web 28 of the flue box. Forwardly projecting tabs 42 struck from the wall lill are adapted to engage the sides of the ilue box 20 to position the hood laterally with respect to the opening 2i.

In the particular hood shown, the front wall is formed to provide a pair of louvers t3 shaped to deflect the air and hot gases downwardly and outwardly over the top of the range. Dirt or soot carried by the gases in thus deposited on the range top 5 from which it can be wiped up with a minimum of effort. Soiling or discoloring of the adjacent wall surfaces is thus eii'ectually avoided.

It will be apparent from the foregoing that the invention provides novel means for venting the i. In a gas range having a horizontally disposed worling top extended rearwardly of the back wall of the range, an upright back guard extending along the rear edge of the working top and having its front face spaced rearwardly from said back wall, said working top having an opening located between the back wall and the front face of said back guard, an oven disposed below the working top' and having a vent in said back wall, an elongated flue box secured to said baci: wall and in communication with said oven through said vent, said flue box having its upper end projecting through the opening in said working top in spaced relation to the front face of said back guard, a removable cap member mounted on the projecting end of the iiue box, said cap member having a rear wall portion adapted to be inserted between the projecting end of said flue box arid the front face of said baci: guard to frictionally hold the member in place upon the flue box, and a forwardly and downoven and the space at the rear of a range of the type adapted to be mounted flush against a wall. Hot gases from the oven suitably diluted with cooler air from the space at the back of the range are discharged over the top of the stove and forwardly of the backguard so as to prevent soot or dirt carried thereby from being deposited on the adjacent wall surfaces. The discharged gases are deflected by a hood structure which is readily removable for cleaning purposes. In general, the venting means is simple in c0nstruction yet efficient and reliable in operation.
