24 Claims.

This invention relates to a new and improved sheet metal base construction especially designed and adapted for use with cooking ranges but suitable for use with other cabinets.

One of the principal objects of my invention is to provide a base, each end portion of which has the main body portion thereof formed from a single piece of sheet metal generally L-shaped, one leg of the L defining, a side wall for the base and the other leg of the L defining an integral front wall for the base, both leg portions being formed to channel-shaped section for strength and rigidity and so as to conceal the raw edges and present rounded upper and lower edge portions on the base, the flanges of the channel being inwardly directed from the side and front walls.

Another important object consists in the provision of a base, the L-shaped end members of which are formed from sheet metal, as just described, and have sheet metal brace pieces formed to channel-shaped section and welded by their flanges to the flanges of the L-shaped end members, the braces, in turn, serving as attaching members connectable to the bottom plate of the range and also as supporting feet to rest on the floor.

Still another object consists in the provision of a base, consisting of sheet metal L-shaped end members, as just described, each of which has a laterally directed flange on the front wall portion thereof slotted for reception of a key lug on the adjacent end of a toe plate arranged to be mounted detachably between the end members of the base to close the front opening beneath the range for better appearance, without however interfering with good ventilation under the range.

A further object consists in the provision of a base of the kind mentioned having upwardly projecting studs thereon insertible in spring clip type fasteners carried on the bottom. plate of the range for snap fastening of the base on the range, whereby to facilitate the final assembling of ranges in the display room and in the home and avoid damage such as commonly occurred where projecting legs or base portions formed rigid non-detachable projecting parts of the range. The base plate in accordance with my invention has attaching portions thereon perforated so that each stud may be entered selectively in either one of two holes differently spaced relative to the ends of the range, depending on the design of the range onto which the base is being applied, it being desired to have the base lie flush with the outside of the range regardless of difference in design.

The invention is illustrated in the accompanying drawings, in which- Fig. 1 is a, perspective View of a domestic cooking range having a base made in accordance with my invention;

Fig. 2 is a perspective view of the lower portion of another range with a base thereon made in accordance with my invention; Figs. 3 and 4 are vertical sectional details through the right end lower portion of the ranges of Figs. 1 and 2, respectively, showing how the same base end member is applicable to the bottom plate in either one of two positions to suit the difference in design of the ranges;

Fig. 5 is a plan view of the complete base removed from the range; e

Fig. 6 is an under-side view of the bottom plate of the range, and

Figs. 7 and 8 are vertical sectional details on the lines 'I'I and 88 of Figs. 3 and 5, respectively.

Similar reference numerals are applied to. corresponding parts throughout the views.

Referring first to Fig. 5, the base is indicated generally by the reference numeral 9, and comprises two end members Ill and I I for the left and right ends of the range, respectively, and an intermediate toe plate l2 which extends across the front below the range. The end members are interchangeable, as will soon appear, being substantially identical throughout except for the fact that the location of the fastening studs or dowels I3 on the top makes the one end member Ill usable only on the left hand end and the other end member II usable only on the right hand end of the range, as will soon appear. The studs I3 are, in other words, attachable to either one of two flanges on the braces or supports I4 and I5. The ranges indicated generally by the reference numerals I6 and I! in Figs. 1 and 2 each have a bottom plate I8 of rectangular form and dished, as indicated at I9, to provide a recess in the bottom of the range to accommodate the upwardly projecting studs I3 when the range is set on the base, resting on the braces I4 and I 5, as indicated in Figs. 3 and 4, the bottom plate I8 having small attaching plates 23 welded in the so-recessed portion I9 thereof carrying spring clip fasteners 2| for connection with the studs I3.

The bottom plate I8, in accordance with the disclosure in the copending application ofstanley H. Hobson, Serial No. 311,715, filed December 30, 1939, forms a part of the welded chassis of the range, the part indicated at 22 in Figs. 3 and 4 being an inner oven Wall welded by means of its bottom flange 23 onto the top of the bottom plate. The welded chassis, as disclosed in that application, is enameled all over with porcelain enamel, and thereafter the outer jacket parts, cooking top, and so forth are applied, 24 in Fig. 3 indicating an outer oven wall and 25 insulating material, such as rock wool, between the

walls

22 and 24. In like manner, 26 in Fig. 4 indicates an outer oven wall spaced from the inner oven wall 22 for the range H, the space between the walls being filled with insulating material, as indicated at 25. It will soon appear that substantially the same base is usable with either of the ranges I6 and I1 regardless of the greater overall length of the range I! resulting from its having the outer end walls 26 spaced farther from the chassis, the end members I and II being attachable to the bottom plate in either one of two positions, as'illustrated in Figs. 3 and 4, so as to come flush with the outside of the range regardless of the difference in design. The base 9' for the range I1, as will soon appear, is the same as the base 9, its end members I0 and II being the same as the end members for the base 9, but its toe plate I2 being slightly longer than the toe plate I2 to compensate for the fact that the end members l0 and II are farther apart in the base 9' than in the base ;9. v

The end members In and II for the base 9 or 9' are of one-piece sheet metal construction and generally L-shaped, so as to provide a side wall 21 on one leg of the L and a front wall 28 on the other leg of the L integral therewith. Each end member has the sheet metal thereof bent to V channel-shaped section, so as to provide upper and

lower flanges

29 and 30 along both legs of the L for strength and stiffness. The braces or supports I4 and I are also of one-piece sheet metal construction and bent to channel-shaped cross-section to provide upper and lower flanges 3| and 32 to lend strength and stiffness. The braces or supports I4 extend diagonally with respect to the front corners 33 and have their ends entered between the flanges 29 and on the two legs of the L, and have their flanges 3| and 32 welded to the

flanges

29 and 30, as indicated at 34. Needless to say this greatly strengthens and rigidifies the base. The other braces or supports I5 are entered only at one end between the.

flanges

29 and 33 and have their top and bottom flanges 3I and 32 welded to said flanges, as indicated at 35. The braces I4 and I5 each has intermediate the ends thereof an upwardly embossed pad portion 36 formed from the flange 3|. In like manner, the bottom flange 32 has a downwardly embossed pad portion 31 formed therefrom. The upper pad portions 36 provide supports for the studs I3 which are inserted in holes 38 provided therefor in these portions, as indicated in Fig. '1. Corresponding holes 38' are provided in the other pad portions 31, as shown in a Fig. '7, so that the studs I3 can be mounted in either location depending upon whether the end member ingquestion is to be used on the left hand end or right handend of the range. The lower pad portions 31 on the various braces form supporting feet for engagement with the floor, indicated at 39. in Figs. 3 and 4. The fact that the end members are of identical construction and permit withdrawal of the lugs 41 from the slots.

advantage inasmuch as it means QWQI C 0 7.

-when the bottom plate and reduced trouble and expense all along the line. Wide surface engagement of the supporting foot portions 31 makes for easier sliding of the range and less likelihood of damage to the floor or floor covering over which the range may be moved or on which it may be set. The entire base is also of pleasing appearance, due to the fact that no raw edges of the sheet metal parts are exposed, the

flanges

29 and 30 being bent inwardly as illustrated so that the upper and

lower edges

40 and 4| of the side and

front walls

21 and 28 are neatly rounded, as clearly appears in Figs. 3 and 4.

Fig. 3 and as also indicated in Fig. 6, each has two holes 42 provided therein for entry of the stud I3 in either location. The spring clip fastener 2I provided in connection with each of these plates is fastened in place by means of a pair of screws 43, and there are two sets of holes 44 provided for these screws, one pair on opposite sides of each hole 44, as clearly appears in Fig. 6. When the bottom plate I8 is provided on a range like that shown at I6, the spring clip fastener 2! is mounted in register with the innermost hole 42, as shown in Figs. 3 and 6, but I8 is used on a range like that shown at IT, the spring clip fasteners 2I are mounted in register with the outermost holes 42, as shown in Fig. 4. The studs I3 on the

base

9 or 9 cooperate with the spring clip fasteners 2| in the same way in either location,

as should be evident from Figs. .3 and 4.

Laterally projecting flanges 45 are provided on the ends of the front walls 28, as shown in Fig. 5, extending toward one another from the opposite ends of the range. tical slots 46 provided therein for reception of key lugs 41 provided on the ends of the toe plate I2 or l2 in the manner shown in Fig. 8. In that way the toe plate is detachably mounted and is held securely enough to avoid any likelihood of its being accidentally displaced. On the other hand, the housewife may on occasion remove the toe plate easily by lifting the same enough to 46. The toe plate can thereafter be replaced just as easily. When the toe plate is in place between the end members Ill and II, it closes the front opening beneath the range so as to present a neat appearance without, however, interfering with free ventilation beneath the range.
