4 Claims. 1

The invention relates to bread toasters of the domestic type utilizing electric current for preparing toast at the table, and the invention consists in novel features of the toaster body described below.

One object of the invention is to simplify the construction of the toaster body by adapting the same to be made of relatively inexpensive parts and with relatively inexpensive equipment, thus reducing the cost of the finished article.

Another object is to minimize the number of screws, rivets, or similar fastening means, thus reducing the assembly expense. Also it is desired to eliminate exposed screw heads, rivet heads, etc., thereby improving the appearance of the finished article.

Another object is to form a box-like body with downwardly converging sides and ends without requiring complicated dies or numerous parts.

Another object is to provide the toaster with a readily removable crumb tray which may be detached from the body without inverting the toaster, thereby facilitating the discharge of crumbs or the like from the interior of the toaster Figure 3 is an exploded top view of the base forming and crumb tray-forming parts of the toaster, the upper portions of the base-forming part being tilted outwardly somewhat to better illustrate them.

Figure 4 is a bottom view of the crumb trayforming part and is drawn to a smaller scale than Figures 1-3.

Figure 5 is a detail vertical section taken on the line 5-5 of Figure 2 and is drawn to an enlarged scale.

For the purposes of the present invention, the body may be considered as involving a substantially oblong frame-like base unit and an open bottom box-like housing unit. The base includes upright end members I and upright side members 2. A bottom plate 3 is applied to the base member, as described below, but does not form an essential part thereof. All of these parts are formed separately from each other.

The housing unit includes end members 4 and a central member 5 formed separately from each other, then assembled and mounted as a unit on the base. The toaster heating elements and timing mechanism (not shown) are carried on a separate mounting unit comprising upright plates 6, having horizontal flanges l6, and tie bars 1 connect plates 6.

Preferably, but not necessarily, frame members l and 2' are substantially rigid and may be formed of metal stampings, forgings, castings, or of plastics or other suitable material. Bottom plate 3 may be of metal or plastic or other material, either rigid or non-rigid.

Base end members I are curved at their ends to extend longitudinally of the device and are provided with integral horizontal flanges l0. Screws i1, inserted through holes Ila in flanges it, secure base end members I to flanges I6. The inner faces of the ends of member I are offset outwardly, forming lips II, the lower portions of which are spaced from the opposing edges l2 of flanges it. The outer faces of base side members 2 have their end portions offset inwardly, forming lips 13, which are receivable in the space between elements I l and I2 and overlap lips II as side members 2 are dropped into assembled relation with the end members. The interengagement of elements ll, l2 and I3 resist the relative movement of the parts transversely of the device. Lugs M on flanges I ll limit the downward movement of the side members. The exterior surface of the base side and end members adjacent the joint between them may be provided with decorative grooves X to render the joint crevice unnoticeable and to give the base the appearance of having a continuous upright wall. This wall is inclined inwardly and downwardly, as shown. Preferably, the lower edges of members I and 2 are shaped to form legs or feet I 5.

Housing members

4 and 5 are preferably formed of non-rigid sheet material, although stiffened by their shaping and assembly. The housing central member 5 consists substantially of a rectangular sheet pressed into a slightly concavo-convex contour longitudinally of the body, as shown in Fig ure 1, and bent to form the curved top and the downwardly and inwardly inclined sides of the housing, as shown in Figure 2. The top wall is slotted at S to receive the bread slices. Each housing end member 4 is dished, as shown in Figure 1, so that its marginal portions extend longitudinally of the housing and are inclined away from each other. Their edge portions are offset inwardly to form a continuous marginal a recess and an attaching flange 18. The edge portions of central member 5 fit into the recesses and are supported by flanges IS. A tie or brace 59 is riveted or welded at its ends to the upper central portion of flanges IS. The lower portions of central member 5 are riveted or spot welded to flanges l8, as indicated at 20. Although the three

parts

4, 4 and 5, may consist of thin nonrigid sheets, when they are assembled they form a substantially firm box-like housing with an open bottom. The lower portions of the housing sides and ends are inclined inwardly and downwardly similarly to the base walls and may be telescoped within the base whereupon rivets or welds M! are hidden behind members I and 2.

Angular clips 2i have their upright legs riveted or spot welded to flanges [3, or to adjacent portions of the housing sides or ends, and have their horizontal legs resting on flanges l6 and the housing is secured to the base by screws 22 inserted through holes 22a in flanges Iii.

To further secure the parts together and avoid play between them, there are provided several lugs 23 on base members I, each of these lugs being notched downwardly from its upper end, as indicated at 24, and cooperating with the adjacent inner face of member I to form an upwardly opening recess. The adjacent portion of each housing end wall is provided with a rectangular slot 25 which receives lug 23 when the base end 1 parts are telescoped, the housing metal forming the upper end of slot 25 being received in the recess and engaged at opposite sides to be held against flexing. Each base end member I has a lug 2S and each flange Ill has an upstanding ledge J '5 cooperating with lug 26 to engage opposite sides of the lower edge portion of the housing end wall and hold the latter against flexing. Each bas side member 2 has a lug 33 to engage the bottom edge of the housing side member to hold the base member against upward movement.

Depending from flanges I6 are pins 28. Bottom plate 3 is apertured at 29 to permit the projection of pins 28 through the bottom plate when the latter is applied to the lower faces of flanges H). A lever 36 is pivoted intermediate its ends to the bottom face of plate 3 and is notched at 3| to receive grooved portions of pins 23. One end ,oflever 3B is extended through or beneath the adjacent base member I to provide a projecting handle 32 by which the lever may be manipulated manually from one position in which it engages pins 26 to another position in which it disengages the same. When the lever and pins are disengaged, plat 3 may be dropped and any crumbs which may have collected thereon may be removed.

Each of the four pieces of the base frame is easily cast or pressed without requiring complicated molds or dies and without requiring substantial' machining. Similarly, each of the three parts oi the housing is readily pressed out of blank sheets without requiring expensive dies. These eight parts, i, I, 2, 2, 3, 4, 4 and 5 are so constructed that they may be produced easily and economically and assembled readily and will cooperate when assembled to constitute a firm, serviceable, neat-appearing body forming a toasting chamber C and compartments P for timing mech- 'anism, switches, etc. (not shown) By constructing and assembling the housing parts as described, the body may be given the somewhat bulbous contour indicated in th drawing which would be difficult, if not impossible, to

provide in a one-piece stamped housing. There is little or no waste or scrap. By constructing and assembling the base parts as described, the latter may be given the generally oblong contour, but with bulged ends and sides corresponding to those of the housing, without machining the parts. The housing and base, when assembled, tend to hold each other rigid and are readily secured by the four screws 22.

Obviously, some of the interengaging elements may be shifted to cooperating parts and details of the structure may be varied without departing from the spirit of the invention, and the exclusive use of such modifications as come within the scope of the claims is contemplated.
