2 Claims. l

This invention relates to burners of the type and kind generally employed in restaurants, lunchrooms and similar places. More particularly, the invention deals with a burner unit which is mounted to swing from a normal operative position, to a raised or perpendicular position to facilitate cleaning and repair to the burner, :as well as the counter or table surface disposed beneath the burner. Still more particularly, the invention deals with a burner unit of the character described having means adapting the same for use with stove accessories, such for example, as broilers.

The novel features of the invention will be best understood from the following descriptions when taken together with the accompanying drawing in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views, and in which:

Fig. l is a plan and sectional View of a burner unit made according to my invention, with part of the construction broken away.

Fig. 2 is a section on the line 2-2 of Fig. 1, on an enlarged scale, with part of the construction broken away and indicating in dotted lines, the raised position of the unit.

Fig. 3 is a partial section on the line 3-3 of Fig. l, on an enlarged scale, and indicating part of a broiler.

Fig. 4 is a partial section on the line 4--4 of Fig. 2; and

Fig. 5 is a partial section on the line 5--5 of Fig. 4.

In the drawing, I0 represents what I term a swingable burner unit which, as indicated in Fig. 2, is adapted for mounting on a counter or other support I I to normally assume a horizontal position thereon, as shown in full lines and to be raised to a vertical position at the back of the counter, as indicated in part, in dotted lines in said ligure. In the construction shown, the unit I0 is economically constructed from a U-shaped strip or band, fashioned to form a iront Wall portion I2 and side walls I3 and I4, this U-shaped structure forming the frame of the unit, which is pivoted to a fixed angle-iron strip I5, secured to the rear portion of the counter II, the pivot being formed by pins IB and I1 :arranged in upstanding end bearing walls I8 and I3 on the strip I5.

Considering Fig. 3 of the drawing, it will appear that these bearing walls extend well above the vertical back portion 20 of the angle-iron strip. Arranged upon the frame is a top grill 2 plate 2|, which forms a cover for the top of the frame or the burner unit and this grill plate can be detachably mounted in any desired manner. The plate has an aperture 22 therein, note Fig. 3, to facilitate coupling of a broiler, as later described.

Joining the walls I3 and I4, inwardly of the pivots IB and I'I, is a cross-strap or bar 23, which forms a support for one of a number of gas burners 24, only one of which is shown in the accompanying drawing, as Well as .a support for a gas service or supply pipe 25 for servicing the broiler, as later described. The burners 24 may be of any desired construction, as will be apparent.

Mounted in the frame of the unit I0, on the inner surface of the front wall I2 of the frame, is a long gas supply tube 26, preferably having a free mounting in the side walls I3 and I4, asindicated by the clearance in the aperture 2, in- Wardly of the supporting pin 25. This mounting facilitates alinement of the tube 25 with the swinging mounting of the gas supply pipe 23, which couples with the tube 26. The pipe 23 has at its inner end, a coupling 33, having a conical ground seat in opposed walls thereof, as seen at 3 I for a conical extension 32 on a fitting 33. The conical extension 32 is apertured, as seen at 34, for supply of gas to the pipe 29, and thus to the supply tube 2B. On the extension 32 is an outwardly projecting threaded rod or reduced threaded portion 35 for reception of a nut 36 to control tensioning of a spring 3l, which means the tapered extension 32 is in seated position in the bores 3|, as will be apparent. The taper is exaggerated in the accompanying drawing simply from a standpoint oi clarification, and it will also be apparent that the extent of the bearing surfaces 3i can be varied.

The fitting 33 comprises a relatively high tubular body 33, from which the extension 32 extends at the upper portion thereof, as clearly seen in Fig. 5, the gas supply pipe or a litting thereon, as at 39, being coupled with the tubular body 3B, as clearly seen in Fig. 4 of the drawing. The fitting 39 .passes through the back wall 2t and is threaded into the tubular body 33 and a nut 40 is employed to secure the parts in firm engagement with a xed angle-iron strip I5. To avoid strains on the fitting 33, as a Whole, the tubular body has an extension 4I, with a pin 42 arranged in the Wall 20, to act las a key.

Considering Figs. 2 and 4 of the drawing, it will be apparent that the axis of the extension 32 is in direct alinement with the pivots I6 and Il,

so that in swinging the unit vertically, the pipe 29 swings on the extension 32, thus maintaining constant supply of fuel at all times to the tube 26 and the burners. It will be understood that this will maintain the conventional pilot lights which are employedl inv burnersfof the kind under consideration in operation. Pilot lights are not shown, as they form no part of the present conception. Y A Y Y In Fig. l of the drawing, theV unit -lil-is.-hro'lten away and only one burner 2-4 is shown. However, a number of these burners may'rbe4 employed, andY each burner will have a control valve., as at. 43 note Fig. 2, directly coupled with thetubeZ. and having a ingerpiece portion 44 disposed outwardly of the front wall l2. .At the rear end of the valve is the usual Venturi' tube` il?, "leading'to the burner 24, to control admission of airrsnpply to the burner.

The rear end. of lthe pipe .25. has a. fitting 45 having an upwardly directedgas dischargednorzzle -41 which extends. above the frame and through the aperture 22 in the platefzl. The aperture22 facilitates reception of the downwardly extending Venturi tube 48 of a broiler, part of whichis .indicated in dot and dash lines at.49 in Fig. 3. The broiler can be ofthe general type and kind disclosed in my prior. application Ser. No. 58,569l filed November 5, 1948, in which a similar type of tube is employed. rThe tube 4 8. includes an adjustable apertured sleeve "5D which acts as an air valve controlling the supply of air tothe Venturi tube 48.

From the foregoing, it will be apparent. that such accessories as a broiler can be arranged upon the plate/2l and be serviced from the supply pipe 25, which has a valve control forwardly of the front wall I2, as-seen at 423.'. In other Words, similar to the ngerpiece control 44 of the valve 43.

With a burner unit of the character described, it will be apparent that the entire unit can be swung from the full line horizontal position, seen in Fig. 2, toa raised position at the back oa counter or table H facilitating cleaning of the various parts of thelunit, as well as. the upper surface o'f the counter or table. When the unit is in the raised position, the counter or table can be utilized for other purposes., In raising the unitthe plate 2l can be removed so as to clean the upper structure of the unit prior to moving the same into thev raised position and all of Vthe foreign matter or removed particles will collect on the counter and can then be removed therefrom, or--a collecting sheet can befirstdisposed on the counter before the cleaning operations-are performed.

It will be understood that my invention is adapted for use in connection with units of any type or kind and using any type or hind of burners. In this connection, the grill plate can be of such structure as to fully expose some of the burners for direct heating of receptacles arranged thereover.

Byconstructing the unit of the. metal strips and other parts, it will be readily seen that the unit can be constructed very economically. The only parts which are of special construction are the

fittings

3U, 33 and 46. All other fittings, pipes and the like can be of standard construction.

Throughout the speciiicati'on, reference is made to a counter or table top, and it is understood'that this counter or table top may comprise any relatively fiat horizontal supporting surface upon which the burner unit is arranged. In some instances it may comprise the top of a range. The distinctive feature in thepresent invention resijdesin the provision of the: swinging frame supp'orting'burner or similar service mediums, so that at. any time, the unit can be swung into a raised position for cleaning or other purposes, as hereinlset forth.v
