I 2 Claims.

This invention relates to a new and improved baking pan assembly and more particularly to a plurality of individual pans held in assembled relation by means of an encircling band iron.

Multiple pan units of this character are in general use, and the present invention relates to improved design and construction of such an assembled unit. Heretofore, folded pan units have been shown with rivets secured through folded portions to the band iron, the rivet heads being covered by inner folds and not exposed on the inner surface of the tray proper. A feature of the present invention comprises the riveting of seamless pans to the band iron in such manner that the rivet heads are not exposed.

It is an object of the present invention to provide a new and improved multiple pan assembly in which the pans are positively located and retained in assembled position.

It is a further object to provide a construction including seamless pans.

It is also an object to provide a construction in which pan elements and the band iron are interlocked and keyed together.

It is an additional object to provide a pan assembly which is simple in design and construction and adapted for commercial production and use.

Other and further objects will appear as the description proceeds.

I have shown certain preferred embodiments of my invention in the accompanying drawings, in which- Fig. 1 is a perspective view of a two pan assembly;

Fig. 2 is a perspective view on an enlarged scale of a half section of the front band iron in the open position;

Fig. 3 is a fragmentary section showing the end of a pan and the adjacent band iron partially assembled;

Fig. 4 is a view similar to Fig. 3 but showing the parts fully assembled, being taken on line 4-4 of Fig. 1;

Fig. 5 is a fragmentary section on line 5-5 of Fig. 1; and

Fig. 6 is a fragmentary elevation, on a reduced scale, of the portion of the side wall.

In the drawings, referring first to Fig. 1, the two pans II are held in assembled relation or strapped (together by a circumferentialiy extending band iron which comprises the front and rear elements l2 and the side elements l4. While only two pans I I have been shown in the drawing, it will be understood that the invention applies to any suitable number of pans.

The top edges of each pan II are bent around a continuous reinforcing wire it, as shown at I! in Figs. 4 and 5. As shown in Figs. 3 and 4, the ends of the pans H are provided withrivet tabs or extensions [9 which extend downwardly well below the reinforcing wire it. The pans shown are of the seamless drawn type and, While the present construction is particularly adapted for such pans, it will be understood that other types of pans may be used if provided with the elements described, including the tabs IS.

The front and rear band irons [Z are formed, as shown, with a lower bead 2! comprising a reentrant fold joining an inner fold 23 and an outer fold 25. The outer fold 25 has its upper edge formed in an arcuate head 21 adapted to partially enclose the portion ll of the pan tab it which is formed around the reinforcing wire I 6. The upper edge of the inner fold 23 is turned outwardly to form the arcuate flange 29 which fits against the lower face of the wire [6, as best shown in Figs. 3 and 4. The ends of the band members [4 are curved to extend around the corners of the adjacent pans H and are provided with rivet tabs 30.

The side band iron elements l2 are shown in cross section in Fig. 5 and are provided with lower beads 32 and upper beads 34. semicircular tabs 36 are struck inwardly from the band iron l4 immediately below the bead 34 and are bent upwardly behind the wire It, as clearly shown in Fig. 5. These tabs 35, together with the bead 3d, firmly lock the band Hi against vertical movement relative to the pan. These tabs 36 leave semicircular opening 38 visible in the band l4 along the sides of the assembly.

The method of assembling the band iron will be apparent from the drawings. The front and rear elements l2 are fitted against the pan ends, as shown in Fig. 3, with the pan tab 19 extending down between the inner fold 23 and outer fold 25. The rivets 40 are carried by the inner fold 23. When the folds are forced together and the strap iron closed to its final position, as shown in Fig. 4, the rivets 4|] extend through openings 42 and 44 in the inner and outer folds. During this final forming operation of the assembly, the tab I9 is forced firmly around the wire l6 and up under the flange 29, as shown in Fig. 4.

The side bands M are forced in place with the tabs 36 in position and the band sections secured together by means of the rivets 46.

While the pans H are held firmly in the band iron by the connections described, spacing members may be provided, as shown in the drawings.

3 The form shown comprises a substantially rectangular strap 41 with its sides fitting under the adjacent pan beads and its ends secured by rivets 48 to the front and rear band irons [2.

The construction shown and described constitutes a rigidly assembled multiple pan unit having smooth, unbroken inner pan surfaces. The preferred form shown is to be understood as illustrative only, as it is capable of variation to meet differing conditions and requirements, and I contemplate such modifications as come within the spirit and scope of the appended claims- I claim:

1. A multiple pan unit comprising a plurality of pans and band iron members connecting the ends of the pans, the individual pans each having reinforcing wire extending about its upper edge, with edge portions of the pan formed about the wire, the band iron comprising a member folded about its lower edge to form inner and outer portions, the pans having tabs extending from their ends fitting between the band iron portions and, secured thereto, the outer band iron portion having its upper portion bent inwardly to partially enclose the reinforcing wire, and the inner band iron portion having its upper portion engaging the under face of the wire.

2. A multiple pan unit comprising a plurality of pans and band iron members connecting the ends of the pans, the individual pans each having reinforcing wire extending about its upper edge. with edge portions of the pan formed about the wire, the band iron comprising a member folded about its lower edge to form inner and outer portions, the pans having tabs extending from their ends fitting between the band iron portions and secured thereto, the outer band iron portion having its upper portion bent inwardly to partially enclose the reinforcing wire, and the inner band iron portion having its. upper portion engaging the under face of the wire, the ends of the band iron members being bent around the corners of the end pans of the units and lateral band iron members secured to said ends of the first mentioned' band iron members to form continuous circumferentially extending means for securing the pans together.
