2 Claims.

This invention relates to household gas cooking stoves and particularly to gas ranges of the oven type.

. The present tendency in apartment and household kitchens is to reduce the space allowance and size to a minimum. The space allowed for stoves parallel to the wall of the kitchen is accordingly reduced and a storage cabinet is provided on the stove and extends above the level of the burners for accommodating various utensils, containers and the like, thus compensating for the lack of space otherwise. i

In many instances, only a limited and definitely established space in which the range may be accommodated is provided and, due to changes and variations made in construction, the chim ney or exhaust flue built into the house is not positioned in exactly the proper position for connection to the range located in the space provided.

In addition, it is desirable that the exhaust flue for the range, particularly for the oven, be installed permanently on the range by the manufacturer in a condition in which, when the range is installed, the flue will lie in proper position for connection-with the kitchen chimney opening in the kitchen wall.

The principal object of the present invention,

therefore, is to provide on a range a permanently installed flue which may be adjusted readily both in length and laterally of the stove so as'to meetv and properly align with the wall opening therefor, even though the wall opening may be positioned to one side or the other of, or above or below, its proper position.

Other objects and advantages will become apparent from the following specification wherein reference is made to the drawing in which Fig. 1 is a perspective view of a gas cooking range with a flue embodying'the principles of the present invention installed thereon;

Fig. 2 is a rear end elevation of the range illustrated 'in Fig. 1;

Fig. 3 is an enlarged sectional view of the flue, taken on a plane indicated by line 3-3 'of Fig. 2; and

Fig. 4 is a fragmentary side elevation of the upper end of the flue, showing a modification.

In the drawing is illustrated a household gas cooking range, designated generallyas I, having an oven compartment 2, in the rear wall of which is provided an exhaust opening 3 through which the products of. the oven may be discharged.

At the rear wall of the range is a splash panel .4 which extends above the top burner level of the range and supports acabinet 5 suitable for accommodation of.cooking utensils and various containers. At the vertical margins of thecabinet 5 are rearwardly extendingflanges 6 which, when therange is in position adjacent to the wall of a room in which installed, define with the wall of the room and the splash panel t, a readily accessible concealed pocket. The wall of the room is provided with the usual flue opening with which the range flue is to be associated, the wall opening communicating with the usual chimney, not shown, of the kitchen or house.

As mentioned in the objects, however, due to the constructional details, the wall. opening is not placed in exactly the same position relative to the location of the range in all instances. There is provided, therefore, on the stove, a flue which is permanently mounted thereon at the time of manufacture. This flue,'designated generally at I0, comprises two relatively longitudinally telescoping sleeves low and lllb, the upper sleeve lllb being closed at its upper end, as indicated at III. The lower sleeve Illa is open to the atmosphere in the room, as indicated at l2, for the full cross sectional area of the sleeve at its lower end and is open at its upper end for communication with the sleeve lllb,

Mounted near the lower end of the sleeve Him is a collar l3, as better illustrated in Fig. 3, which is permanently fixed to the sleeve with its axis at 90 degrees thereto. The collar extends through the opening 3 in the rear wall M of. the oven with its axis horizontal and is flanged over both interiorly and exteriorly of the wall M, as indicated at I31 and l3b, so as to bacon nected to the rear wall I4 of the range permanently. The connection is sufficiently loose to permit rotation of the collar l3 about its axis relative to the wall l4. If desired,'however, the collar may be" secured to the range wall and constrained to a non-rotative' relation therewith, the relative rotation being between the collar and sleeve Ina. Thus the flue l may be swung about the axis of the collar I 3 to dispose it to the right or left of its normal upright position.

The sleeve Hlb is provided at the face opposite the collar I3 with a permanent collar IS on which may be mounted a short slip. sleeve, adjustable axially of the collar [5, so as to be received the desired distance in the opening of the room wall. Such a slip sleeve is shown in Fig. 4 and designated l'a. The sleeves low and lot are snugly flt together in the relatively telescoping relation so that the sleeve lDb may be moved longitudinally while in any rotated position of the flue ID for positioning the collar IS in alignment with the wall opening.

By the combined swinging and longitudinal adjustment, the collar l5 may be brought into coaxial relation with the room wall opening and readily inserted therein or connected thereto by the short sleeve l5a.

As better illustrated in Fig. 2 in which various positions of the flue ID are illustrated in dot-dash lines, the flue may be swung through an angle of degrees in a plane parallel to thesplash panel 4 and the length adjusted to correspond to the full height of the range andcabinet 5 or to one half such length. Since the variation in the position of the wall opening is always within these limits, the self-contained flue is provided in which the exhaust opening is universally adjustable to all positions in a plane parallel to thepanel 4 and may readily be installed in operating position in the wall opening of the room.

Since the flue i0 is open at the bottom as indicated at l2, any backdrafts in the chimney of the house discharging into the flue ID are relieved so as to prevent extinguishing the flames in the oven and out-blowing of products therefrom.

The end portions of each sleeve Ilia and lob, op-

posite to the collars l3 and I5 respectively, are provided with arcuate recesses I612 and IE1), respectively corresponding in diameter to the diameter of the collar of the other sleeve so as to provide a greater range of adjustmenhi All of the working parts are concealed by thecabinet 5 andflanges 6.

Having thus described my invention,

I claim:

1. In a kitchen range, an upright rear splash panel, upright side flange walls extending rearwardly therefrom for spacing the stove from a wall, a flue permanently mounted by one end portion on the rear wall of the stove for swinging movement to and fro between the flange walls and generally along the splash panel, said flue being extensible and contractible in a direction generally parallel to the splash panel and lying within the space defined by the splash panel and flange walls and being concealed thereby.

2. The combination with a gas cooking range having a flat substantially vertical rear wall, of an exhaust flue permanently mounted on said wall and communicating therethrough, said flue being rotatable in and having a discharge portion extensible in a plane parallel to the rear wall.
