(01. 99—401) 1 2 My invention relates to toaster casing struc tures and has for its object to provide an im proved casing structure of this kind. A further object of the invention is to provide the base l2 during the assembly of the side wall to the base, as described hereinafter. The base 12 is also provided with a plurality of openings 24, four in number, for the reception of self an improved casing structure for a toaster which (R tapping screws '25 which are employed for fasten . ing the side wall II and the partitions l3 and I4 may be readily and economically fabricated from a relatively small number of parts without weld ing or riveting operations. to the base l2. ‘ The side wall H is preferably formed from a single piece of material and may be elliptical in These and other objects are effected by my in vention as will be apparent from the following 10 con?guration, as best shown in Fig. 4. The meet ing margins of the sidewall are brought together description and claims taken in connection with the accompanying drawings, forming a part of adjacent one end of the toaster and are provided with inturned ?anges 26 and 21 which are spaced this application, in which: apart to de?ne a slot 28 in which the handle. ll ' Fig. 1 is a side view of my improved toaster casing structure with portions thereof broken 15 operates. - The ?anges 26 and 21 are engaged by ?xed legs 29 and 3| of a hairpin key piece or away for the sake of clearness of illustration; keeper 32 which maintains the meeting ends of Fig. 2 is an elevation viewed from the right the side wall II in proper position and prevents hand end of Fig. 1; separation of the meeting ends. The keeper 32 'Fig. 3 is ‘a sectional view showing apparatus is retained‘i'n position by overturned portions 33 in and adjacent the plane indicated by line of the inward ends of the ?anges 26 and 21 (see TIL-III of Fig. 1; Figs. 4 and 5). A small portion of the upper ends Fig. 4 is a sectional view taken along the line of the meeting margins of the side wall is en IV—IV of Fig. 1; and Fig. 5 is a sectional View showing a detail and gaged, as shown at 34 in Fig. 5. ' The lower edge of the side wall structure Il is taken along the line V--V of Fig. 4. may be provided with a relatively small inturned Referring now to the drawings, I have shown flange 35 which engages the upper surface of my improved casing structure including a top the base l2, and this ?ange 35 is provided with wall or dome l0 carried by a side wall structure, inwardly-extending cars 36 into which the self generally shown at H and supported by a base l2 of any suitable material. The base [2 carries 30 tapping screws 25 are threaded during the as sembly of the side wall to the base. In this a pair of partitions l3 and 14 which de?ne an connection, it will be noted in Fig. 1 "that the intervening toasting chamber or oven l5, access partitions l3 and I4 include horizontally-ex openings to which are shown at IS in the top wall tending supporting portions 31 and 38 which are Ill.

It ‘is to be understood that side wall H is also provided with a pair of ears the usual heating elements are carried by and 39 having respective openings 4| formed therein between the partitions l3 and I4 in any well un derstood manner, and that the bread carriage 40 for receiving the projections 23 formed on the base structure. These ears 39 position the side which carries the bread slices is movable up wall II on the base during its assembly to the wardly and downwardly in the oven l5 by means base and also assist in preventing separation or of a handle shown in part at I‘! and having a inward movement of the marginal ends of the gripping portion l8 arranged exteriorly of the casing II when assembled to the base I2. casing.

The sides of the side wall II are then for the passage of bread to and from the toaster moved inwardly to the position shown in the mechanism, a side ‘wall structure carried by the drawings and the keeper 32 is slid over the in baseand engaging said top wall, said side wall turned ?anges 26 and 2-1, after which the inner structure encompassing the toaster mechanism ends of the ?anges are bent over the keeper, as shown at 33, to ‘retain the keeper in engage and .formed as a unit with its opposed ends dis ment with the ?anges 26 and 27. As set forth heretofore, the upper edge of the keeper 32 de ?nes a support upon which :the ‘right-hand end of the-top wall I!) rests, as ‘shown in Fig. 5. This ~ is all that is necessary in the assembly of the top wall and the side wall. In assembling the 'casingstructure to the base, ‘the partitions I3 and ‘I4 supporting the vtoaster posed adjacent each other, said opposed ends of the side wall structure having'respective clamp ing members formed thereon and extending in wardly of the casing structure and at least a portion of the opposed ends of the side wall struc-‘ ture being. spaced to de?ne a slot through which said handle projects, a keeper having spaced apart legs engaging said clamping members and preventing separation of the casing ends- and structure .(not shown) are set. upon the base 30 means for retaining the keeper in engagement with the openings'in the horizontal portions 31 with the clamping members. and‘38 of the partitions l3 and M approximately 2.
