WAR-D AND PAUL S. WARD, OF CINCINNATI, OHIO, ASSIGNOR TO ASHLEY IE. WARD, ING, OF CINCINNATI, OHIO, A CORPORATION OF OHIO SET OF BAKING FANS Application filed January 28, 1930. Serial No. 423,959.

The present invention relates to a set of baking pans formed of a plurality of 1nd1- vidual pans united by su1table strapping to form the set. N r The invention relates more especially to o the form of strapping employed for uniting and holding the pans in the set, so as to produce a strong, rigidly assembled set and one which can be readily stacked.

Figure 7 is a detail perspective view Referring to the illustrated embodiment of the invention, the set comprises three 111- dividual baking pans 1 2 and 3. These pans are united into a set by a strappnig means surrounding the set and indicated generally by reference numeral l. The strapping means comprises an inner or core strap 5 and an outer strap 6 which may be, for convenience, designated as a jacket strap s1nce its edges are bent around and partially enclose the core strap. I

The core strap 5 is a flat piece of strap iron. It may be formed in a single piece bent to entirely surround the set, or it may be formed in two pieces each piece going halfway around the set and having the joints between the pieces as indicated at 7 in Figure 1. The jacket strap 6 is made of strap iron. Tt may be formed in a single piece winch entirely surrounds the pan, or it may be formedin two pieces, the joints between which are int5 dicated at 8 in Figure 1. It will be noted that the joints between the ends of the core straps and jacket strap pieces are at the ends of the set and are staggered.

The jacket strap 6 is bent to provide a flat, substantially vertical middle portion 9, an inwardly bent top flange 10, and an inwardly bent bottom flange 11.

The baking pans 1, 2 and 3 are preferably die drawn, each from a single piece of metal, and are provided with outwardly extending top flanges, indicated generally by reference numeral 12. The outwardly extending flanges 12 are bent over the core strap 5 and are securely clamped between the top of the core strap 5 and the upper part of the jacket strap 6.

. As shown in the drawings, the flange 12 is pressed down to form an outwardly facing shoulder 13 which fits against and shields the edge of the jacket strap 6. Beyond the shoulder 13 the flange 12 has a horizontal portion 14 which lies beneath the upper flange of the'jacket strap, and beyond this is a downwardly projecting portion 15 of the pan flange 12 which lies between the inner and outer side faces of the core and jacket straps 5 and 6. The pans are first drawn and their flanges bent into the shape shown in the drawings. The pans are then rigidly spaced in recesses in the assembling dies and the core and jacket strap 6 are applied and the edges of the jacket strap clamped around the core strap as shown in Figure 6, thereby firmly gripping the outwardly extending pan flanges 12 between the strap members 5 and 6.

In order to assist in spacing the core strap 5 away from'the sides of the pans during the assembling operation, a small U-shaped piece of metal 16 is spot welded at 17 to the side of the core strap 5, the legs of this U- shaped piece loosely engaging the sides of the middle pan 2 to space the core strap therefrom during the assembling operation.

It will be noted that the jacket strap 6 is bent over and its upper flange 10 extends inwardly around the entire circumference of the set. This protects the lighter tin plate metal around the top of the set, and the jacket strap provides a smooth surface along its tops and sides even at the corners of the set. The inturned lower flange 11 of the jacket strap 6 covers the bottom edge of the core strap and gives a smooth finger hold for lifting the pan.

The strapping construction, providing as it does a flat core strap, a jacket strap bent around and partially enclosing the core strap, with the edges of the pan flanges gripped between the two straps, atl'ords great rigidity for the strapping means in proportion to its weight, which an important consideration, since the sets of pans are frequently subject to abuse and deforming strains.

The sets of baking pans are usually stacked for handling on the trucks in the bakery, so that it is desirable, if not essential, that some spacing means be provided whereby the pans can be piled in a stack and pulled apart without sticking to each other. Such spacing means is provided by downwardly extending projections 18 of the acket strap 6 at each corner of the set. In forming the acket straps the lower edges of the straps at the corner portions of the set are cut so that the metal along the sides and ends of the set may be turned up to form the lower flanges 11, leaving a straight portion extending downwardly to form the stacking spacers 18. Around the corners of the set the spacers 18 are formed by the curved downwardly projecting'extensions of the jacket strap 6. As the sides of the extensions 18 the metal is slit a short distance horizontally, as well as vertically, to leave two cars 19 which are bent inwardly as shown in Figure 1. The bottom of the curved portion 18together with the bottoms of the ears 19 forms a foot which rests upon the inwardly turned top of the jacket strap of a set of pans immediately beneath it when the pans are stacked, as shown in Figure 2 The metal of the jacket strap 6 is fairly heavy, thus forming a strong spacer 18. Moreover, this spacer 18 is formed as an extension of and therefore integral with the jacket strap 6, forming a unitary and strong construction. The spacers 18 are located at the very outermost four corners of the set, whereby when the pans are assembled in a stack there can be no tendency of the pans to see-saw on each other as would be the case where spacing projections are located at points intermediate the length or wi h of the set. The arrangement of the bent-over top flange of the jacket strap and the feet of the spacers which bear against it is such that the contact is between the relatively heavy metal of the straps, and the tin plate metal of the pans is shielded against contact of the spacer feet.

The spacers 18 project downwardly sufficiently so that the outside of the bottom of the upper pan is held away from soiling contact with the inside of a lower pan into which its fits when the pans are stacked, thus contributing to the sanitary condition of the bakery.

The flanges 12 along both sides of the pan 2 and along the sides of the pans 1 and 3 which are adjacent the pans 2, are bent downwardly, as indicated at 20 in Figure 3, leave ventilating openings 21 between the pans. The downwardly bent flanges 2O serve to stiffen the pan flanges 12 at these points between the pans where they are not gripped by the strapping means.

The clamping grip of the core and jacket straps 5 and 6 against the outwardly turned flanges 12 of the middle pan 2 is sufiicient to prevent any shift of the middle pan 2 longitudinally toward or away from the pans l and 3. Positive spacing means may be provided, if desired, by striking down the metal of the upper flange 10 of the jacket strap at the points 22 between the pans, or ends of the downwardly bent portions 15 of the flanges 12 at the ends of the middle pan may extend across the space between the pan to abut against the ends of the downwardly bent portions 15 of the end flanges 12 of the pans 1 and 3 between the core and jacket straps 5 and 6.

The strapping means for the set of baking pans as above described is strong and very rigid in proportion to its weight. The acket strap bent over the tops of the pan flanges protects the lighter tin plate metal around the entire top edge of the set of pans. The grip aflorded between the core and jacket straps gives a rigid anchorage for the upperedge: of the pans and holds such upper edges very securely. The spacers 18, which are formed as integral downward extensions of the strapping means, are very strong and rigid and permit the sets of pans to be built into a firm stack in which there is no tendency of one pan to wobble or see-saw with respectto a pan beneath it.

While we have specifically illustrated and described the preferred embodiment of our invention, it is to be understood that the invention is not so limited but may be other wise embodied and practiced with n the scope of the following claims.
