portion 16, having the laterally extending flange portions 17 and being provided with openings therein above each of the burners 14 to 17 inclusive, for respectively supporting detachable grids 24 thereover. The grids 24 are polygonal in form, although they may be of any other shape, and of course, the top wall C is suitably provided with cross beams 25, of well known construction connected with the marginal portions 16 of the top wall, and formed to detachably receive the grids 24 thereon. It is of course understood that a detachable grid is provided for each burner, so that in the example shown there are four burners and four individual grids therefor.
Referring to the form of invention A, the entire top wall structure G including the grids 24 thereof is bodily movable into a desired adjustable spaced relation with respect to the burners. The arrangement is shown in Figures 1, 2, 3 and 4, and includes a pair of rotatable shafts and 31, secured by end and intermediate brackets 32 in a horizontal rotatable relation at the insides of the opposite range stationary frame walls 11 and 12 respectively, as shown in Figure 1 of the drawings. The shafts 30 and 31 are provided with end pinions and 36 respec tively, housed within the end brackets 32; the latter being hollow and over-roofing the pinions 35 and 36 as a protection therefor, as shown. in Figures 2 and 3 of the drawings. These end pinions 35 and 36 of the shafts 30 and 31 respectively have the teeth thereof in meshing engagement with racks 37 and 38 respectively. The racks 37 and 38 are dove-tailed for vertical sliding in the brackets 32, and their upper ends are detachablyconnected as shown at 40 in Figures 2 and 3 of the drawings, to the corners of the top wall C, preferably at a marginally solid portion 16 of the top wall C. The racks 37 are straight, and connected in right an led depending relation from the top wall 6, and. it is to be noted that there is a rack at each corner of the top wall C meshing with a pinion 35 or 36, as the case may be. Upon counter-rotation of the shafts 30 and 31 it is apparent that the top wall C and the grids therewith will be elevated and lowered. This rotation of the shafts 30 and 31 .is accomplished by providing a transverse operating shaft 45, shown in Figures 1 and 4 of the drawings, the ends of which-bear in the intermediate brackets 32 of the shafts 30 and 31, the right end of the shaft 45 extend ing through the wall 12 of the stationary frame of the range and having a lever or crank wheel 47 secured therewith to permit manual rotation of the shaft 45. The shaft 45 haskeyed therewith worms 49 and 50, housed in the intermediate shaft housings 32 and respectively meshing with worm gears 51 and 52 keyed on the intermediate portions of the shafts 30 and 31 respectively. The worms 49 and 50 are pitched in opposite directions, as are also the worm gears 51 and 52, so that upon rotation of the shaft 45 the shafts 30 and 31 will be rotated in opposite directions, to either feed all of the toothed racks 37 and 38 upwardly or downwardly, to accomplish the elevation or lowering of the entire top wall structure of the range with respect to the plurality of burners which cannot be elevated or lowered.
It is to be particularly noted. that the racks 37 and 38 are so dove-tailed in their respective brackets 32 provided therefor, that they are held against tipping. The housings 32 have the tops thereof slotted merely to permit the racks 37 and 38 to slide therethrough. Otherwise the said housings of the brackets 32 cover the gear details therein against collection of foreign materials.
, In the form of invention B, a pair of shafts 60 and 61 are rotatably supported at the inner sides of the walls 11 and 12 of the stationary structure of the range. Thus, the shaft 60 is supported at its ends by brackets 63 secured to the wall 11 at the inside thereof, as shown in Figures Sand 6; an intermediate bracket 64 also being provided on the wall for said shaft. Similarly the shaft 61 is rotatably supported at its ends in bearing brackets 66 secured to the inside surface of the wall 12 and extending normal thereto. Furthermore, an intermediate bracket 67 is provided on the wall 12 for the shaft 61.
At the endsthereof the shafts 60 and 61 are each provided with radially extending arms 70, having pivotal connection at their free ends with links 72 which extend upwardly and are pivotally connected at 74 with brackets or bearings 7 5 secured to the undersurface of that portion of the top wall structure 0 which is laterally of the grids, as shown at 16 With this connection of the shafts 60 and 61 at their ends with the wall C it is ap parent that upon rotation of the shafts 60 and 61,'in the proper direction, the top wall C will be elevated and lowered with respect to the burners to accomplish the purposes of the invention above outlined. It is to be particularly noted that the end connection of linkage upon the shafts 60 and 61 insures that the top wall structure C will find an elevating and lowering connection at each corner thereof.
For the purpose of simultaneously moving the shafts 60 and 61 in the same direction, I prefer to provide an operating rod 80, extending transversely through the stove range below the burners thereof, which at its remote end is pivoted at 81 with an arm 82 keyed on the shaft 60. The arm 82 is radial above mentioned. The operating rod 80 at its opposite end extends transversely through an opening provided in the wall 12 of the stove, as shown at 85 in Figure 8 of the drawings. This opening 85 permits the rod 80 to be elevated and lowered slightly adj aeent the wall, so that any of a number of notches 87 provided along the lower edge of the rod may be notched in a detent flange 88 which is secured on the wall 12 at the opening 85, for the purpose of holding the rod 80 against accidental inward or outward movement, as would ordinarily cause an elevation or lowering of the top wall of the gas range. It is to be particularly noted that the operating rod 80 has an arm 89 pivoted therewith at 90; the arm 89 being radially of and rigid on the shaft 61 above mentioned. Since such an operating means necessitates that both the shafts 60 and 61 rotate in the same direction to enable the elevation and lowering of the top wall C, it is intended that the arms 70 of the shafts 60 and 61 lie parallel, or substantially parallel, and the connecting links 72 of both of said shafts are preferably also in parallelism.
From the position shown in Figure 6, upon moving the rod 80 inwardly upon disconnec tion of the notch 87 from the detent 88, it is to be noted that the arms 70 .will be moved downwardly, and through the link connections 72 the top wall C of the range will be lowered to place the grids closer to the burners. The position of burners andgrids, as shown in Figure 6, are in their maximum spaced relation, while the closest spaced relation'of the same is designated in Figures 7 and 8 of the drawings.
proposed to vary the'distance between burner and grid, so far as I am, aware,.no prior device shows an arrangement which enables elevation and lowering of the entire top wall of a range, together w th its grids, relatlve t0 burners.
Various changes in the shape, size, and'arrangement of parts may be made-to the forms of lnventlon herein shown and described,
without departing from the spirit of the invention or the scope of the: claims.
I claim: I
