4 Claims.

This invention relates in general to stoves, and has more particular reference to stove top covers of simple construction, which may be raised and lowered into and out ofposition with ease of operation. This application is a division of my application Serial No. 665,941, filed April 13, 1933. An important object of the invention isthe provision of a stove top cover which is insulated against heat when the table top is lowered after the burners have been used. g

A further important object of the invention is the provision of a stove top cover which may easily be raised or lowered without requiring the moving or. adjusting of other parts.

Another important object of the invention is Figure 1 is a front elevation of a stove embody- ,ing my present invention;

Fig. 2 is a transverse vertical section through the top of the burner box unit of a stove embodying my invention;

Fig. 3 is a rear elevation of the burner with the top in closed position;

Fig. 4 is a fragmentary rear elevation with the 35 top shown in raised position;

Fig. 5 is a section taken substantially on the line 5-5 of Fig. 3; and

Fig. 6 is a section similar to Fig. 5 and showing 40 the top in raised position.

For the purpose of illustrating my invention I have shown on the drawings a stove construction generally, comprising a frame IS, a combined oven and broiler unit l6, and a burner box unit l1. Four legs l8, of suitable form and: construc- 45 tion, are provided at their tops with flat parts arranged at right angles and adapted to receive four angle iron rails which may be bolted in place. These angle iron rails are arranged so that the apex or corners of the angles are adjacent and 50 with an opening through the stove.

As more particularly describedin my co-pending application, of which this is a division, the combined oven and broiler unit I6 and burner box unit I! are so constructed'that they fit within,

the bottom frame thus provided and restupon the tops of the side and end rails. The burner box unit, to which the instant invention more particularly relates, is a completely enclosed integral unit and contains a drawer l9 mounted below a burner containing section, indicated at 2 I. 5

As will lie-apparent from the drawings, the burner box unit comprises an integral unit and consists of a bottom plate .of pressed sheet metal, side walls, a back wall 22, a top rectangular frame 23 of angle iron construction, and a front cast 10 rectangular frame 24. These parts are so constructed and arranged as to greatly facilitate assembly and to produce a rigid, substantial structure of relatively light gauge material.

The top frame consists of four angle irons 15 welded together at their ends, the two side angle irons extending across'the ends of the front and back angle irons. The horizontal flanges of all four angle irons are at the top, and those of the side angle irons extend outwardly and those of the front and back angle irons extend forwardly.

Viewing Fig. 2, the front cast frame 24 is provided with an inset top flange 25 at the opening. Bolts 26 are arranged to extend rearwardly from the top of the frame '24 through openingsin 25 the front angle iron of the top frame.

The back wall 22 consists of a single flat sheet of metal secured at 21 to the rear face of the rear angle member of the top frame and to the inner face of the rear upturned flange of the bottom plate.

As shown in Fig. 2, the burner box unit is provided with a cast iron stove top 28 and a a skeleton vessel supporting grate 29 of usual or preferred construction. A front wall of the burner compartment 3| is provided to fit within and suitably secured to the top part of the front cast iron frame 24 of the stove. A manifold 32 for the burners is arranged within this unit and back of the wall 3|. It enters the unit through an opening at the rear and is'disposed along one side wall and across the front of the unit. It is held 'in position from the front cast frame and to this ,end clamping membersor arms 33 are cast integral with the frame and cooperate with companion clamping members 34 to hold the manifold in position. Burner valves 35 are arranged to extend up from the manifold and have gas outlets 36 adapted to be arranged in the mixing chambers 31 of burners 38. These burners are supported at the front upon the gas outlets 36 and at the rear upon brackets 39 of angle form which extend down from a fastening means 4|.fro'm the top angle iron 23 along the front of the back wall and thence forwardly be A fixed sheet metal apron 44 extends up from andis spaced above the top plane of the burner box unit I! and is rigidly secured thereto. This apron extends longitudinally of the burner box unit or stove and'is' provided at its ends with flanges 45 extending'rearwardly to allow ofits being rigidly secured by vertical brackets or posts 45 spaced slightly away from the side edges of the apron, as shown in Figs. 3 and 4. These posts 45 are secured at their lower ends to the burner box 1 3 indicated at 41 by bolts .48 or other suitable fastening means. Adjacent the top and bottom of its flanged edges, the apron is secured to the vertical supporting posts at 49 by bolts or other suitable fastening means. As shown in Figs. 5 and 6,-the apron with its supporting brackets or posts is spaced rearwardly from the vertical plane of the back wall 22 of the burner box unit, for a purpose which will later be described. v A table top stove cover, generally indicated at 5|, is provided for the burner box unit and is or may be providedwith a handle 52 to facilitate raising and lowering. This top is hinged at 53 along the rear of the stove and preferably consists of two metal sheets, the topmost one of which is flanged downwardly at 54 at the front of the stove, and thence inwardly at 55 to provide a box-like edge. The inwardly extending portion 55 rests upon a projection 55 of any suitable material secured either to the stove top or to the cover.

The top plate of the table top extends rearwardly through an opening or slot 51 provided between the top of the back wall 22, extension 58,

and the lower edge of apron 44. This extension 58, extending longitudinally of the rear wall of the stove, is secured to the back 22 at 21 and forms a part of the hinge 53. The rearward extension of the plate 5| is bent upwardly and thence rearwardly at 53 to receive an arm 5| to which one end of a counterbalancing spring 52 is connected. The other end 52 of the spring is fastened to the back of the stove at 53 as may be observed in Fig. 3 and two such springs are provided.

The lower sheet of the table top of the stove, indicated by reference character 54, is flanged at its front end, then extended forwardly until it contacts the inwardly extending portion 55 of the top sheet of the table top where it is bent so as to overlie .and rest upon the inwardly extending portion 55 where it is spot welded or otherwise suitably secured. At its rear end it is flanged downwardly at 55, then rearwardly and upwardly, as indicated at 55, and against the back extension 58. This construction creates a box-like structure 51 which provides an air space within the table top to insulate its upper surface from the heat of the burners when the top is lowered after the burners have been in service. If desired, this space may be filled with insulating material of any desired character.

It will be apparent from the foregoing description that the table top or cover may be readily raised or lowered without aflecting the relative position of the other parts of the stove. When the top 5! is raised that portion of the top plate which extends rearwardly of back wall extension 58 rests against this extension and the cover portion itself rests against the apron 44. as shown in Fig. 6.

It will be manifest that when the table top is raised the counterbalancing spring will serve to securely support and maintain it in upright position, and that because of the novel construction of the parts, very little efiort is needed to lower the top to closed position. When the top is closed down over the burners its weight will be sufficient to overcome the tension of the counterbalancing spring.

It is thought that the invention and many of its attendant advantages will beunderstood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
