Application inea November 6, 1025. serial No. 61,277.

My improved gas'stove is especially designed by ine as a cooking stove although certain features thereof are desirable for embodiment in heating stoves.

The main objects of the invention are:

First, to provide an improved gas stove which is highly eiicient for broiling, roast' ing and like purposes and which ishighly efficient and requires a minimum of attention on the part of the operator. I

Second, to provide an improved stove having these advantages which is readily adapted for a variety of uses.

Third, to provide an improved gas stove of the radiating element type which is well adapted for structures of considerable size and at the saine time is strong and rigid.

Objects pertaining to details and econo mies of my invention will deniteiy appear from the detailed description to follow. The invention is clearly defined and pointed out in the claims. y

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. 1 is a front structure embodying t provements.

screws 15'.

Fig. 10 is a section on a line corresponding to line 10-10 of Fig. 9 showing further details of the driving means.

Referring-to the drawing, the supporting parts or skeleton of the body or casing of my improved heater comprise a pair of end members 1 which are preferably a casting and have extended base portions 2 terminating in feet 3 and forwardly projecting overhanging top portions 4. Y

The end members are provided with attaching lugs 7 adapted to receive the bolts 8 securing the back frame 6 thereto. The back frame has a panel 9 secured thereto b `means of the screws 10. The back frame as forwardly projecting lugs 11 supporting the v rear end of the hood-like top 12, this top having a downwardly projecting rib 13 resting on the lugs as shown in Fig. 5. The top haskdownturned fianges 14 at its ends embracing the upper edges of the end members. At its forward edge the top is provided with inwardly projecting ears 15 engaged by the -ends of the base portions of the end members.

A supporting plate 25 is supported by lugs 26 on the end/members and is further secured by screws 27 engaging the downwardly projecting flange 28 at the rear edge of the plate. This supporting plate has a downwardly projecting ange 29 at its front edge and has holes 30 therein alined with the tips 31 of the burner 32, the burner being suspended from this supporting plate.- I

The ireback 33 is mounted on this sup- 100 porting plate as are also the radiating elements 34 which are of the tubular foraminated form and are arranged over the openings 30. A retaining bar 35 engages the top of the fireback and has forwardly projectl ing arms 36 at its ends which are secured to the end members 1. The plate 25 has a flat top on -which the radiating elements are retained by means of the rod 37 which has a downwardly ofset loop 38 in the central por- 1I tion thereof engaged by the bar-like head 39 of a screw engaging the flange 29 of the supporting plate.

The ireback is further retained by means of the

lugs

40 and 41 projecting inwardly, from the end members to engage the front edges of the ireback. Finishing or corner plates 80 are secured by means ot' the screws 81 to the front flange of the supporting plate to overlap the lower end of the ireback adjacent the end members.

A hearth plate 42 is mounted in front of the supporting plate, the end members being provided with supporting lugs 43 for this hearth plate. The upper edge of the hearth plate rests against the retaining blocks 80, see Fig. 2. This hearth plate is spaced from the front panel 22 providing an opening between the forwardly projecting arms of the end member base portions to receive the drip pan 44. This drip pan rests upon inwardly projecting ledges 45 on the end members. The hood-like top projects well forward so that it overhangs a considerable portion of the drip pan when it is arranged on its suport.

p On each end member is a support 46 for slidably supporting the

bars

47 and 48. These bars have racks 49 engaged by pinions 50 on the adjusting rod 51. The rod 51y has a hand-wheel 52 at each end so that the supporting bars are simultaneously adjusted. The rod 51 is supported on the rearwardly projecting brackets 53.

The supporting har 48 is provided with a driving chuck 54 adapted to receive a spit 44 or other implement, and a driving chuck 56 adapted to receive the spindle 57 of al grill 58 or the like. The supporting bar 47 is provided with notch-like bearings 59 and 60 for the spindles of the spit and grill.

In order to limit the rearward movement of the supports when a grill is in position and thus avoid liability of injury to the parts by moving the grill so far rearward A that it would engage with the frame or with other parts of the stove, I provide a stop 61 which is pivoted at 62 to be engaged by the spindle of the grill whereby it is thrown to erected or operative position as shown in Fig. 6. A hook-like stop 63 on the stop 61 limits the upward swing of thestop 61 which, when in erected position, is adapted to coact with the supporting slide 46. l

The

chucks

54 and 56 are connected by

gears

64 and 65. The chuck 54 is provided with abeveled gear 66 meshing with a rgear 67 on the shaft 68 disposed parallel to the supporting bar 48. A housing 69 is provided for the gears 66 and 67 and also for the

gears

64 and 65. The shaft 68 has a non-circular portion 7 0 slidable through a worm gear .71 on the gearbox 72. This gear 71 meshes with a gear 7 3 on the shaft 7 4 which in turn has a worm gear 75 at its lower end meshing with provided the worm 76 on the driving shaft 77 of the motor indicated at 78. This provides a reduction speed drive for the spit chuck 54, the grill chuck having a further reduced drive by means .of the

gears

64 and 65.

This driving connection permits the adjustment of the supporting bars to properly position the object being cooked, such as a roast indicated at 79 on the spit 55.

The shaft 70 isr formed of telescoping sections connected by a shear pin 82, see Figs. 9 j and 10, which is designed to break or shear oil in the event that the load lon the implement is too great or in the event that it comes into contact with some object to prevent turning, preventing breakage at some other point in the driving mechanism. 4

In practice the supports may be adjusted to bring the roast, for instance, into close relation to the radiatingeleinents for searing the surface and then adjusted for slow cooking ii desired. The continuous turning secures uniform cookin and prevents burning.

I have il ustrated and described my improvements in one form in which I have embodied the same in practice. I have not attempted to illustrate or describe various embodiments or adaptations which I contemplate as I believe this disclosure will enable l those skilled in the art to embody or adapt my improvements as may be desired.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
