DEBS BAKING PAN Original Filed Sept. 2?, 1928 2 Sheets-Sheet 2 Patented Jan. 12, 1932 UNITED. STATES LOUIS H. DEBS, OF CHICAGO, ILLINOIS BAKING PAN Original application filed September 27, 1928, Serial- No. 308,669. Divided and this application filed 7 October 12, 1929. Serial No. 399,173.

This invention relates to baking pans and more particularly to a multiple-pan construction in which the pans are mounted within a band iron frame having transverse braces at intervals. The present invention is also concerned with a novel form of rivet connection, an improved end protection plate, etc., all of which are more fully hereinafter set forth. The features of invention herein claimed were first disclosed in my application filed September 27,1928, Serial No. 308,669, of which this is a division.

Asuggestive embodiment of my invention is illustrated in the accompanying drawings in the manner following:

Figure 1 is an end elevation of several pans mounted in a unitary frame to produce a multiple-pan structure;

Fig. 2 is an enlarged detail in section on line 2 of Fig. 1 showing one of the connecting rivets as it appears when first set in lace; p Fig. 3 which is a similar view shows the rivet after being upset;

Fig. 4 is a detail of a rivet having a con-5 vex head, as shown in Fig. 2;

Fig. 5 is a similar view of a rivet having a concave head;

Fig. 6 is a perspective view of a multiplepanunit having a frame which includes a band iron with which is also associated a pair of protection plates; 1

Fig. -7 which is a detail in section on line 77 of Fig. 6 shows one of the protection plates secured in place;

Fig. 8 which is a detail in section on line 8 of Fig. 6 shows one of the braces which extends between adjacent pans;

I Fig. 9 is a sectional'detail taken on line 9 of Fig. 7; and

. Fig. 10'" which is a detail in perspective shows the brace construction at one of its ends.

Each of the pans shown is made preferably ofsheet metal with a bottom 15, and oppositesides and ends 16 and 17 respectively. At the corners are the usual triangular'folds 3/ which lie adjacent the ends, as seen is Figs. 2 and 3. The upper edges of walls and-ends may be outwardlycurled for reinforcement and other purposes, as will be presently explained.

A pan produced in accordance with the preceding description may be united in a row with others of like construction, as suggested in Figs. 1' and 6. For this purpose, I utilize a common supporting frame which may include an iron band or strap 20 which is extended along the sides and ends of the pan. row. Such a band may have its upper edges rested against the under face of the shoulder formed by the curled edges of the several pans, as shown in Fig. 2, and any appropriate means may be used for securing the band to the pans. An improved fastening for this purpose is suggested in Figs. 2 to 5, wherein I have shown a rivet 21 having a pro-formed head 22 which is curved either convexly as in Figs. 2 and 4, or concavely, as in Fig. 5, the thickness of the head being substantially uniform in either case. Such a rivet may be inserted through a pan adjacent its corners so as to pass through the extra thicknesses afforded by its folds, and also through the band iron frame which is arranged exteriorly thereof. Preferably, a recess or seat 23 for the rivet head is prearranged by the use of an appropriate die so that the rivet will initially occupy a position as shown in Fig. 2. Thereafter, when the rivet end is upset, two things will happen: its outer end 24.- will be spread, as shown in Fig. 3, and the head 22 will be flattened out to substantially the form which is shown in the same figure. This final flattened form will be reached regardless of whether the head be initially convex, as shown in Fig. 4, or concave, as shown in Fig. 5. In either case, the flattening of the head will cause a spreading of its edges without any appreciable displacement of the metal. The result of this operation is that the rivet head will be tightly fitted within the recess or seat which is provided in the pan walls for its reception. By this construction 95 the rivet head is seated snugly and with an improved fit within the pan recess, so as to avoid protruding upon the inner face of the pan wall; by this construction also I eliminate any crevice betweenthe rivet head and the pan, thereby obviating possible accumulation of dirt and grease.

It iscontemplated that a series of rivet connections, one for each of the folds at the pan ends, will be arranged between the band iron frame and the pans which are mounted therewithin. This means of. connection. is best illustrated in Fig. 1. Another form of connection between the pans and bandiron frame is suggested in Figs. 6 to 10 inclusive to'which reference will now be made. The pans therein shown may be of the general kind already described, in that their edges are curled over to provide their own reinforcement without the aid of any supplementary means, such as a round wire.

As shown in Fig. 6, I position a channel brace of sheet metal having its side walls 26 curled over at 27' and under the curled By intercurling in this manner the side walls edges of the pans to which it is connected.

of the brace and the edges of the pan walls, the two parts are interlocked so that the brace serves as a medium of connect-ionbetween the adjacent pans. As suggested in Fig. 10, at

their ends the side walls 26 of-the channelbrace are curved outwardly at 28 in general conformity with the curvature of the pan corhere, these walls stopping approximately I flush with the outer face of the pan ends:

pending ears 30 adapted to lie approximately flush with the outer face of the pan ends.

I From these ears one or -morelugs 31 are struck outwardly in position for insertion through registeringslotsin holes in the band irons, the ends of these lugs being thereafter clinched or upset to establish a secure connection between the brace ends and the band iron frame.

At each end of the pan row I may arrange a protection-plate 32. As shown, this-plate is secured in place by having its upper edge 33 intercurled-with the corresponding edge of the adjacent pan side 16'after the manner already described in connection with the brace of Fig. 8. Thisprotection plate may extend. downwardly and then inwardly, as shown, to provide a lip 34 which underlies the lower edge of the end pan. In addition, I have shown at each end of the protection plate van ear 35' which is extended laterally along the proximate end walls 17 of the adjacent pan. These ears may desirably be .of triangular form andalong their upper edges are intercurled with the corresponding edges connection-may also be provided, and, as shown, this takes the form of lugs 36 which are outstruck fronrt-he ears for extension through registering holes or slots :37 in the band iron frame. When the ends of the lugs are clinched or upset the connection thus provided becomes fast. It will be noted that the end protection plates constructed as described afford also a protection which extends around the corners of the multiple-pan unit, and that the ears which are fastened to the band iron frame at points remote from the ends of the pan row serve also to secure the end protection plates against movement from the position shown.

The present invention is advantageous in that each pan may be formed with an edge reinforcement which requires no separate or additional parts, a pan of this kind lending itself to a novel and improved securement withinv a frame which carries other like pans, the means employed inv connecting the pans in place being inexpensive, quickly applied,

and highly suitable to meet all service condi tions. i
