9 Claim.

This invention relates to improvements in the construction of the front frame for the socalled cabinet type of gas ranges, being specifically directed to a novel form of frame which will afford protection to the vitreous enamelled sheets forming the body and doors of the gas range and at the same time eliminating the necessity of vitreous enamelling the frame itself, while at the same time providing for the i artistic treatment of the complete gas range.

Further, it is an object of this invention to provide at a minimum of cost a steel frame of durability and rigidity adapted to cover the edges of the side and the top sheets of the gas range, thus permitting assembly with concealed bolts and further providing for a frame which maintains the oven linings in position while protecting the edges thereof.

In the design and construction of gas ranges, the front frame from time immemorial has presented specific dimculties with respect to its structural aesthetic and utilitarian features. Cast frames which have been used were expensive and liable to warp or be broken, while 0 at the same time presenting the difliculty of properly enamelling the same in mass production. Pressed steel frames require expensive dies in the production thereof and expose fragile surfaces at joints and corners which be- 80 come affected either in shipping or in use. Structural steel frames as heretofore known present a crude appearance in conjunction with the enamelled sheets forming the top, sides and doors, therefore preventing an artistic appear- Sl ance.

The present invention contemplates a front frame surrounding the oven and broiler compartments, constructed of angle or L-shaped sections, in each of which one flange lies in the common plane parallel to the front of the range. By means of this arrangement, in con- Junction with the doors of the various compartments, oven or broiler sections, there is visible when the doors are closed only a thin 46 bead comprising the edges of the respective angle sections which extend across and along the various door sections.

In this manner, the only portion of the frame that is visible is a bead at the top and sides of 50 the stove having very' little surface, which can be finished in ordinary black Japan but will not detract from the appearance of the vitreous enamelled door sections and sheet sections contained within or disposed adjacent said frame and will protect the enamelled sides and top.

while at the same time providing for a contrast to offset and accentuate the enamelled parts. In this manner the cost and difliculty of enamelling of the frame is eliminated and the artistic treatment of the front of the range is simplified.

These and other advantages, capabilities and features of the invention will appear from the subjoined detailed description of one specific embodiment therefor illustrated in the accom- 65 panying drawing, in which Figure 1 represents a perspective view of a stove incorporating the frame.

Figure 2 is a perspective view showing the frame alone.

Figure 3 is a plan view in section showing the relationship of the sides of the oven compartment with respect to the frame.

Referring to the reference characters in the drawing, numeral represents the base frame for the stove, numeral 11 represents the frame for the open burner and numeral 12 represents the front frame for the oven and broiler compartments, the open burner frame 11 being supported on the base frame 10 by means of upstanding brackets 13 resting "on the horizontal flange 14 of the base frame, and the front frame 12 for the oven and broiler compartments being bolted at the base of the sides 15 thereof along the horizontal flange 14 of the base frame.

The base frame, the open burner frame, and the front frame for the oven and broiler compartments are formed of pressed steel and although they are shown each as integral shaped members, it is within the province of this invention to build up each of these members by means of separate angle bars.

Referring in detail to the front frame 12 for the oven and broiler compartments, the side members 15 thereof comprise angle bars, likewise the top member 16, the respective side members having front faces 17 and the top member having front face 18 all in the same plane, and the side members have right angular rearwardly extending flanges 19 disposed in planes near the center of the compartments formed thereby, and the top member 16 has a right angular flange 20 extending forwardly of the flange 18 thereof, so as to comprise the only forwardly extending flange of the frame for a purpose to be later described. A right angular bracket 21 defining the oven and broiler compartments is disposed across the front frame member and fastened to the rearwardly extending flanges 19 of the side members, upright flange portion 22 of the bracket being adapted to be in the same plane as flanges 17 and 18 of the side and top members of the frame.

Referring now to Figure 1, doors 23 and 24 are mounted on faces 17 of the side members, so as to form the front enclosure for the respective oven and broiler compartments. Metallic sheets coated and finished as with enamel or the like are provided for the top of the oven compartment as at 25 and the sides of the oven and broiler compartments as at 26, the sheet on the side furthest away in the drawing not shown being the same in its assembly and disposition as the side sheet 26 shown in the drawing.

It is to be noted that the doors 23 and 24 when in closed position substantially cover the flanges'1'7 of the side members and flanges 18 and 22 respectively of the bracket members, all of which flanges are in the common plane as heretofore described.

Referring now to Figure 1, it is to be noted that sheets 25 and 26 covering respectively the top and sides of the oven and broiler compartments are so disposed as to terminate adjacent the edges respectively of the forwardly projecting flange 20 of the top member and the flanges 17 of the side members, thereby to expose, when the stove is assembled in the manner shown in Figure 1 with the doors 23 and 24 of the broiler compartment closed, an enclosure in which are exposed only the extreme edges of the forwardly extending flange 20 of the top member and the edges of the flanges 17 of the side members, which flanges need not be enamelled but which edges form beads which, when painted black, will provide sufficient ornamental effect, and at the same time produce the necessary structural rigidity required for maintaining the sheets in position.

Further, as may be noted from Figure 1, the door 23 of the oven compartment has its upper surface in contact. with the under surface of flange 20, thus while the peripheral front edges thereof contact with the surfaces 17, and 18, and 22 of the flanges in the common plane of the side, top and bracket members, thereby eliminating the tendency and possibility of escape of heated air or vapors from the interior of the oven compartment when the stove is in operation.

Referring to Figure 3, the frame section has associated therewith, in conjunction with metallic sheet 26, a metallic sheet 2'7 serving as an inner lining for the compartment; the said sheet 27 being offset at its front end portion as at 28 as to permit the exterior face of such sheet to rest against the outer portion of flange 19, and also to cause right angular portion 29 adjacent the offset portion 28 to rest against the edge of the flange 19, thus eliminating the use of bolts for the interior lining.

Although no insulation is shown between sheets 26 and 27, it is within the province of this invention to so construct the compartment as to provide, if desired, for insulation between such sheets.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims:
