Patented May 1, t 1934 UNITED STATES STOVE Frank E. Wolcott, West Hartford, Conn., as-

signor to The Silex Company, a corporation of Connecticut Application November 25, 1930, Serial llo. 498,055 I 7 My invention relates to stoves.

It has among its objects to provide an improved stove and more particularly an improved stove of the type used in restaurants or the like. A further objecteof my invention is to provide an improved gas stove having an improved stand or casing housing the burners and the connections thereto, improved utensil supporting means above the burners, and improved connections for the burners. These a'nd'other objects and advantages of 'my improved construction will, however, hereinafter more fully appear.

In the accompanying drawings I have shown for purposes of illustration one. embodiment which my invention may assume in'practice.

In these drawings,

In this illustrative construction, hereinafter more specifically described, I have shown my improved stove as comprising a casing, generally indicated at 1, and of substantial rectangular form,

one of the I having corner housings 2 which also act to form supporting legs for the casing, while a plurality of burners 3 are provided inside the casing and beneath a supporting grid structure, generally indicated at 5, and gas is supplied to these burners through supply connections 6 disposed in the casing and controlled by control members '7 on the front, of the casing. I

Referring more particularly to the casing, it

i j a 32. claims; (01. 126-40) will be observed that the same comprises a front elongated sheet metal plate 8, a corresponding rear plate 9, and shorter end plates 10 and 11. It will also be noted that the plates 8 and 9 carry on and inside their upper edges corresponding grid holding strip members 12 and 13, ,while corresponding members, 14 and 15, which have no grid holding function, are carried on the upper edges of theplates 10 and 11. Attention is also directed to the fact that the plates 8 and 9 are provided with inwardly extending flanges 16 on their lower edges, while the plates 10 and 11 are provided with corresponding flanges 17 on their lower edges. As shown, both sets of flanges are also spaced or cut away at the corners to provide an open space indicated at 18, while the flanges act as supports for a bottom plate or member 19 having diagonally cut oil corners likewise exposing the space 18, and are connected to thismember 19 by suitable means, as for example, screw connections 20. Here it will also be noted that at each comer the adjacent vertical plates overlap, intumed lateral extensions 21, for example, being provided on the end plates 10 and 11 and connected to ends of the plates 8 and 9 by suitable connecting means such as rivets 22. Thus it will be evident that the casing 1 is of, a rugged, yet simple construction stiffened by the members 12, 13, 14 and 15 and by, the bottom -member 19, while being rigidly connected at its corners.

Upon each of the comers of this casing, housing members are provided substantially 'corresponding to those described and claimed in my co-pending application, Serial No. 498,058, filed November25, 1930. More particularly consider- Referring more particularly to the corner shown in Fignres 4, 5, 7 and 8, it will be noted that the member 2 is thus adapted to be inserted ,from the bottom so that these side and end plates 9 and 10 will be received in the slots 25 substantial- 1y as described in my previously mentioned ap- 1 plication, while the ends of the members 13 and 14 will be received and supported in the enlarged slots 23 and 24 in the member 2. Also it will be observed that in this construction the plate member is provided with a vertical notch 26 in its burners 3.

lower end adjacent one edge of the portion 21, while the plate'9 is provided with a pair of corresponding notches 27 of which the outer notch is spaced the same distance from the corner as the notch 26. Thus it will be evident that the slotted portions 25 on the leg member 2 will be adapted to fit in these notches 26527 and that the parts are securely connected at the'bottom as well as at the top, while the member 2 encloses both the inside and outside of the corner. Here it will also be noted that, as in my previously described construction, a cap 28 is fitted on the top of each leg 2 and connected by a rod 29 extending down inside the corner of the casing, as shown in Figure 4, and connected at its lower end to a foot member 30 by means of a nut and screw connection 31, all in the general manner of my previous application. 4

Referring more particularly to the grid means, it will be observed that the members 12 and 13 supporting the same are of substantially identical construction so that a description of one will suffice for both. More particularly, it will be noted that each of these members 12, 13 is at tached by suitable means 12', herein rear screws and front rivets, to its outside plate, and that it is disposed flush-with the top edge of the latter and provided with a series of apertures and notches adapted to support the grid means 5. Taking the member 13, for example, and referring to Figure 6 which shows slightly more than one half of this member in elevation, it will be observed that the same is provided at its right hand end and just inside the corner with a pair of laterally spaced apertures 32, and that adjacent them to the left four laterally spaced open notches 33 are provided in its upper surface. Next to these notches to the left is another pair of apertures 32 and next to these at the left, another set of four open notches 33. Beyond the latter notches and midway between the ends of,

the member 13 is another pair of apertures. thesefithe moreremote corresponds to an aperture 32 in being unthreaded, while the other, nearer to the notches and marked 34, is threaded. The rest of the member 13 being of the same construction heretofore described needs no further description, nor does the member 12 save to say that its aperture corresponding to the aperture 34 is oppositely threaded.

Thus with the two members 12 and 13 so constructed, it is made possible. to seat rods 35 in each of the registering unthreaded apertures 32. As shown, the oppositely threaded apertures 34 are also connected by a single tie rod 36 oppositely threaded on its opposite ends and preferably provided with means to facilitate turning the same and herein in the form of an aperture 36' adapted to receive a suitable pin or tool. It will also be noted that removable rod or grid members are disposed in the notches 33 which in the arrangement described are in the areas above the Here it will also be observed that these removable grid members comprise oppositely disposed units. More particularly, each comprises a straight rod or grid member 37- having pivotally connected thereto midway between its ends, as by a rivet 38, a co-operating member 39 disposed parallel thereto at its ends and provided intermediate its ends with an arcuate portion 40 connected to the rivet 38, while the two arcuate portions.40 serve to present a substantially round grid substantially spaced above the burner 3.

More particularly considering the gas supply and control connections, it will be noted (Figure 1) that the supply connection or piping 6 is extended through the right hand end of the rear plate 9 and suitably rigidly connected thereto as v at 41 close to the bottom of the same. As shown, it is also extended forwardly along the side 11 and then longitudinally of the casing in the form of an extension 42 close to and parallel to the plate 8 and attached to the bottom 19 of the casing by strips 43. Herein, this extension carries usual burner connections 44 spaced along its length, each of which in turn carries usual longitudinally separable burners 3 and is controllable by a usual controlling member 7. Herein it will also be observed that burners 3 are in the form of single elongated members having an upwardly directed pierced outlet at one end. It will also be noted that each burner is provided with a threaded aperture 45 in its under surface substantially beneath its delivery end and that a supporting rod 46 is threaded in this aperture and also provided with a threaded lower end threaded in a corresponding aperture 47 in a nut member 48 carried in the underside of the bottom member 19, a corresponding aperture of course being provided in the latter. As shown, the member 46 is also provided with suitable turning means, herein in the form of a transverse pin 49, so that it may be readily turned, while the nut 48 is suitably attached to the plate 19 as by rivets 50. Attention here is alsodirected to the fact that the bottom plate 19 is provided with suitable air apertures 51, herein preferably disposed in spaced relation in a plurality of lines extending longitudinally of the same on opposite sides of the line of burners 3. i

As a result of my improved construction, it will be observed that a very rugged, yet inexpensive,

casing is produced which is of the open grid top type, and particularly adapted to use in connection with gas or other liquid fuel type burners. By reason of the improved grid supporting members inside the upper edges of the outer front and rear plates, and the connection to or support of the several grid members on these supporting members, it will be noted that not only is a strong, yet simple, construction made possible,- but that overheating and consequent discoloration of the outer plates is minimized, at the same time that the grids are disposable entirely within the outer plates in such manner as to improve the appearance of the structure and also to eliminate any possibility of the end of any grid being engaged or accidentally thrown out of position relative to the casing during use. It will also be noted that it is made possible to apply my improved comer housing means to this casing in such manner as to increase the strength of the same while producing a very attractive appearance and also to enable a series of casings to be connected end to end by improved connecting members as described in my above mentioned application. Attention is also directed to the fact that the improved grid means are such as, while providing a grid surface of large area, to enable the grid members 35 to be held in position by the tie rod 36 regardless of changes in temperature, and to enable access to be had to the burners and their connections whenever desired through the removable grid units comprising the pivotally connected members 37, 39. It will also be observed that by simply removing one or both of these removable units and adjusting the member 46 supporting the burner, it is possible to adjust the burner 3, as desired, while the member 46 may, whenever desired, be so rotatedas to permit removal of the burner. These and other advantages of my improved construction will, however, be clearly apparent to those skilled in the art.
