BAKING-PAN.

Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed April 10, 1917. Serial No. 160,923.

To all whom it may concern:

Be it known that I, HARRY J. HAIGH, a citizen of the United States, and a resident of Stapleton, Staten Island, borough and county of Richmond, and State of New York, have invented certain new and useful Improvements in Baking-FansQof which the following is a specification.

This. invention relates to that. class of baking pans, largely employed in bakeries, in which a plurality of individual pans are connected together to form a multiple bak- 111g pan.

The principal object of the present invention is to provide means for detachably connecting the pans together, whereby a damaged pan may be removed from the set and anew plansubstituted, or the relative positions of the pans of a set changed to present a different pan or pan surface at the point or points of greatest wear. Another object of the invention is to provide a rigid holding frame to which the individual pans may be rigidly secured; and held against relative movement, without the employment of rivets or other fastening devices exposed at the inner surface of the pans.

A further object'of the invention is the provision of a connecting frame and means connected with the pans adapted to be rigidly interlockedwith the frame to hold the pans to the frame and in proper position relatively to each other. Another object of the invention is to provide a connecting frame adapted to be expanded to facilitate the removal and insertion of the pans.

Another object of vide individual pans having permanently secured thereto means adapted to be detachably and interchangeably connected with a standard type of connecting frame for rigidly securing a-plurality of pans together. In the accompanying drawings, is a perspective view showing one form of multiple pan embodying the invention;

Referring to the drawings by numerals, l designates the individual pans which ma be constructed in any suitable manner. rectangular wire reinforcing frame or memher 2 extends around the upper edge of each pan and is preferably held thereto by bending or rolling the upper edges of the side and end walls of the pan outwardly and downwardly around the frame 2, as shown.

locking lug or member 3 is rigidly secured to each end wall of each of the ans 1 in any suitable manner. I prefer to fbrm the lugs 3 with elongated upper portions 4 and to bend the portion 4 outwardly and downwardly around the end portions of the wire reinforcing frames 2 before the end form. of divided end.

walls of the pans 1 are bentaround said end portions, as shown more clearly in Figs.

3 and 4. The portions 4 of the lugs 3 are preferably of substantially the same length J The pans 1 are rigidly held together, preferably in spaced relation, as shown, within a rectangular connecting frame comprising side bars 6 and divided and extensible end bars. The end bars are riveted to inwardly bent ends 7 of the side bars 6, as shown vat 8, but it will be obvious that the end bars may be formed integrally with the side bars if desired. The end bars of the frame may be dispensed with, if desired, and the pans held together, solely by the side bars 6.

The extensible end bars of the connecting frame are preferably formed of a member or bar 9 having a bifurcated inner end, as shown at 10, and a member or bar 11 having a reduced extension 12 adapted to slide longitudinally within the bifurcated end 10 of the bar 9, as shown in Figs. 5 to 8. The inner end of the extension 12 on bar 11 is hinged at 13 to a plate 14, and the inner ends of the arms or extensions 10 on bar 9 are hinged at 15 to a plate 16. The plates 1 1 and 16 are hinged together at their inner ends as shown at 17. The extensions 10 and 12 are preferably bent or depressed inwardly as shown at 18 and 19. When the hinged plates 14: and 16 are swung inwardly toward the sidewalls of the end pans, as shown in Figs. 2 and 7 it will be seen that the bars 9 and 11 will be pulled'toward each other, the extensionv 12 moving between the extensions 10 until the depressions 18 and 19 are in alinement, whereupon the hinge pintle 17 connecting the plates 14 and 16 may be forced inwardly past center, as shown inFig. 7, into the registering depressions 18 and 19. The bars 9 and 11 are thus locked in contracted position and the side bars 6 are moved inwardly against the end walls of the pans and held thereagainst with the tubular ends 5 of lugs 3 projecting through apertures 20 in the side bars. At polnts above the apertures 20 the side bars 6 are preferably pressed outwardly as shown at 21, to form depressions or seats for the depending portions 3 of the locking lugs. By this arrangement the side bars may lie flush with the end walls of the pans.

Any suitable means may be provided for positively and detachably holding the side bars 6 against the end walls of the pan, if desired, to prevent separation of the pans in case hinge pintle 17 should be accidentally side bars 6 are preferably formed with projections 2A for holding the pins in looking position, the heads 25 of the pins being adapted 24 and engage behind the same when the pins are inserted through the'eyes 23 and the tubular extensions 5 on the lugs 3.

In the embodiment of the invention shown in Figs. 10 to 15, the pans 1 are provided with wire reinforcing frames-2 preferably secured thereto in the manner heretofore described, and the pans are held within an expansible connecting frame comprising side bars 6 and expansible end bars formed of members 9 and 11 connected together by hinged plates 14 and 16 in the same manner as the members 9 and 11 shown in Figs. 5 to 8, except that the depressions 18 and 19 in the extensions 10 and 12 are not shown, it being understood that said depressions may be employed or dispensed with in either embodiment of the invention. As shown in Figs. 10, 11 and 14, the end bars are formed with bent end portions riveted at 26 to the ends of the side bars 6, but the side and end bars may be connected as shown in Figs. 1 and 2, or in tegrally formed, if preferred.

A fastening device is permanently held to the end walls of each pan and comprises a portion 27 bent outwardly and downwardly around the end portions of the reinforcing wire frames 2, as shown in Figs. 12 and 15, and formed with a pair of spaced depending lugs 28 having outwardly projecting portions 29 formed with enlarged heads 30. The side bars 6 are formed with two apertures opposite the end of each pan having enlarged portions 31 through which the heads 30 of the lugs 28 are adapted to pass and reduced portions 32 adapted to receive the projecting portions 29 of the lugs 28 when the pans are moved laterally in the frame to lock the pans to the frame.

To prevent shifting and accidental detachment of the pans, bars 33 are pivoted intermediate their ends onthe side bars 6. It will be seen that when the bars 33 are swung to horizontal position, the opposite ends of the bars engage between heads 30 on lugs on adjacent pans and prevent lateral movement of the pans. It will be observed that the arrangement of the large and reduced portions of the apertures opposite the end pan at the left in Figs. 10 and 11, is the reverse of that of the other apertures in order that when the end pan at the left is shifted laterally to locked position it will be moved closely against the adjacent end bar of the connecting frame. The end bars, or-the expansible joints connecting the divided end bars, desired, and the side bars 6 only.

From the foregoing it will be seen that simple means has been provided for rigidly connecting together a plurality of baking pans in such a manner that any pan of a set may be removed and a new pan substituted therefor, or the relative positions of the pans altered. By this arrangement the period of usefulness of a multiple baking pan may be greatly prolonged by placing worn pans at a point where they will be subjected to less wear and strain, and by substituting new pans for worn or damaged pans.
