Application filed January 13, 1927. Serial No. 160,857.

This invention relates to improvements in stoves, particularly those wherein the prin cipal exposed surfaces are enameled. One of the difliculties encountered in connection with the manufacture of enameled stoves is the fact that the enameled parts have been difiicult to replace without dismantling the linings and burners.

Moreover, one of the chief sources of trouble is the discoloration and cracking of the enamel 'on the front frame, particularly on that part between the upper and lower doors. Cracking of the enamel also results from rigidly connecting together two enameled panels or sections.

One of the objects of the present invention is to provide a construction which ob viates the necessity for an enameled front covering substantially the entire doorarea.

This provides. a door which does not require a nickeled portion enclosing the enameled panel.

The preferred means for carrying out my invention is illustrated in the drawings wherein Fig. 1 is a perspective view of a. stove embodying my invention; Fig.2 .is a

vertical transverse section through the stove on a plane indicated by the line 2 2 in Fig. 1; Fig. 3 is a section taken through the stove on a plane indicated by the line 3 -3 of Fig. 2; Figs. 4, 5 and6 are perspective views showing the construction adjacent the corners of the stove; Fig. 7 is a vertical sectional view throughan oven structure showing a modified form of side construction; Fig. 8 is a section on an enlarged downwardly extending flange 34 ad]acent the rear of the stove. A spring 35 carried scale through the oven showing the connection between the side panels illustrated in 1 panels shown in Fig.

Fig. 7 ;-Fig.'9 is a vertical transverse section through the'connectin str1 between the an Fig. 10 1s a vertical section on an enlarged scale taken through Fig. 3 in a plane indicated by the line 10-10.

0The stove illustrated has a base 10 which is su orted upon legs 11. Surmounting the bil e is an oven, which is bounded by front frame 12, back frame l3,sides 14% and o 15, and a top 16. The front'and back frames are preferably cast members such as aluminum. vThe front frame has openings which i may beclosed by doors 17 and 18 respectively, while, the back frame also has openings which may be closed by a sheet metal member 21. The rear openings in the frame member are made principally to lighten the weight of the casting. By making these framesof cast metal, particularly. of aluminum, I obtain members which are more or less flexible" at the mid-portion when anchored together at the top and bottom. Moreover I have found that an aluminum frame will not discolor when subjected to heat of the usual oven temperature, and that it willtake a sufficiently high degree of polish to preserve a leasing appearance.

The side 14 pro erably has inwardly turned flanges extending around the marginal edges thereof, whilethe side 15 has inwardly turned flanges 26 extending around the marginaledges thereof. ;The bottom flange on the side 14 is arranged to rest upon-the grate frame 27, while the bottom flange on the side 15 is arranged to rest upon a 2 bar 28 which, as shown in Fig. 3- is fastened to the base 10.

Within the oven I provide a false to 30 a which is. attached: to the front and ack frames, and which provides an air space between the oven proper and the enameled top 16. The upper flanges on the side members extend over the false top as illustrated I inFig. 3 and, ifdesired, may be attached thereto in any suitable way. I have shown securing members 31, which are arranged to engage. threaded openings in the falsetop. The top 16 has downwardly extending flangesi32 which are arranged to engage respectively the outer surfaces of the sides 14 and 15. The top moreover has a flange 33 which extends downwardly and inwardly adjacent the front of the stove, and has a top and front framewhile the stove is beingv assembled. This avoids the necessit for an accurate interfitting relationship 0 the cooperating parts, and at the sametime provides a slight overhang at the front of the stove which adds'tothe appearance thereof.

Thetop 16 may be held in place by means of bars 40 which function to hold the cresting 41 in place. These bars may be attached to the rear frame member as shown in Fig. 6. With this arrangement upon removal of the cresting, the top may be lifted from the stove, and then the sides may be withdrawn in an ex editions manner.

In the preferred orm the top is attached to a shelf 42 and is removable therewith as a unit from the stove. The outer end of the shelf is attached to a standard 43. A splash plate 44 illustrated in Fig. -5 has a portion thereof projecting itto the space between the rear frame and th vertical flange on the side 14 wherefore such plate may be readily removed, if desired, after the top shelf has been withdrawn. In this way anyenameledpart which is 'sub'ect to discoloration from heat or breakage rom transit may be easily replaced without disturbing the burner or thermostat connections and without necessitating the breaking of any connections for.

the stove lining.

The grate frame as indicated in Fig. 10 is removably connected to the front and rear frames 12 and 13 by securing members 8 and :9 respectively. In the preferred form the grate frame has lugs 6 and 7 which are threaded to receive the respective members 8 and 9.' In this way the grate frame may also be removed without disturbing any hning or burner connections and in addition the connection permits adjustment between the front and rear'frames and the grate so as to obtain the proper degree of tension upon the side panel.

By means of the construction which I have set forth, the enamel is not apt to be cracked'by mechanical strains, since'the enameled sections are not directly attached to ether. 1

' bottom of the side 14 however,

the frontv rear framemembers by securing means 73 and 74 respectively. A convenindicated diagrammatically at 56, and so place the spring that it normally tends to urge the lower endof the side 14 against a shoulder 57 upon the ate frame.

A modified form 0 side panel construction is shown in Fi 7, 8, and9, wherein two panels '70 and 51 form the outer side oven wall. A connecting strip, preferably a cast member 72, extends transversely of the oven and is adapted to be attached to ient means for attaching the panels to the connected strip is to rovide an. lnturned flange on each panel,

.ment, or by excessive variat1ons in temperjacent the strip, and

.to use one or morepins 7 5 which extend through the flanges and the strip. Each pin may have an intermediate flange 76 which rests within a corresponding recess in the connecting strip, thus obviating the ne'- cessity forany threaded panel securing members, access to which could be had only with By means of my invention I have been able to make a stove wherein any enameled section may be readily removed without disturbing the lining, burner or thermostat connections. This is advantageous since it permits replacement of any discolored or cracked panels in an expeditious manner. A

further advantage of. myinvention is the fact that I have eliminated the necessityfor an enameled front, which, is apt to be discolored either byany material which may.

overflow in the oven, or by the excessive heat to which the oven front is subjected. My stove construction practically eliminates the exposed area of an oven front yet provides an even bearing surface against which the doors may en ageto insure tight closing of the same. further advantage'ous feature of my stove construction is the fact-that the cooperating enameled dpanels are not bolted or otherwise c'onnecte together, wherefore any strains in one panel. are not directly transmitted to another. This tends to min-' imize the panel loss caused by mechanical strains'placed thereon at the point of attachature;
