CAKE PAN.

Application led September 6, 1927. Serial No. 217,684.

This invention relates to pans or containers which may be used for baking or other desired purposes such as the storage of small articles, etc.

One of the objects of this invention is to provide a strong, durable and economical pan which is suitable for the baking of small individual cakes, biscuits, muffins or the like. Other objects of this invention are to produce a pan which will stand the abuse and service incidental to use in the average commercial bakeries. Another object is to obtain the maximum strength with a minimum amount of material. Other objects will be apparent from the description and specifications.

Referring to the drawing:

Fig. I shows a plan view of one form of my invention;

Fig. II shows a side elevation of this form of my invention;

Fig. III shows a corner of a portion of a set of pans in perspective;

Fig. IV shows a developed view of the material which forms the top sheet;

Fig. V shows in perspective a corner view of an alternative of my invention in which the surrounding outer edge is turned upward instead of downward although the preferred form of my invention is that illustrated in Figures I, II and III.

Referring tothe drawing, (l) indicates n. set of pans made in accordance with my invention. (2) indicates a top deck or sheet into which the individual pans indicated by (3) are forced and either pressed or spun. The edges (4) of the top deck or sheet (2) are turned at an angle to the horizontal portion either upward or downward, but preferably downward. The edge (4) therefore forms a substantially continuous surface eX- tending around the sides of the group of pans. A reinforcing rod, wire or strap (5) is attached to edge (4) serving to stiffen and reinforce the edge. Reinforcing member (5) may be round, Hat or of any desired section but I have chosen to represent this member as round for purposes of simplicity. The edges (4) which surround member (2) are bent around reinforcing wire (5) thus serving to stiften the edges and hold wire (5) in position. This bent portion of member (4) is indicated as (6) on the drawing. The adjacent portion of edge (4) is indicated in Figure II as (7 Edges (7) and (4) form a corner (8) which is protected by the overlapping member (9). Overlapping member (9) serves to prevent any opening or crack between edges (4) and (7) and also serves to stiften these edges inasmuch as overlapping member (9) is partly held between the adjacent edge (4) and the rolled portion (6) around reinforcing member (5)- In Figure IV, I have indicated corresponding parts described above by similar numbers.

In Figure V the edges which correspond to (4) and (7) are turned upward and numbered (10) and (11). The overlapping member number 9) in Figure II which serves to unite (10) and (11) is numbered (l2) otherwise similar numbers refer to similar parts.

I am aware that it is not new to unite a series of circular pans or containers into a set by means of a horizontal deck or upper portion, and I do not claim this as my invention. The usual form in which a set of pans are united together consists of a simple, flat, horizontal plate into which the round pans are pressed or spun. Occasionally this plate is reinforced with bead wire with somewhat improved results. On the other hand, the usual type of construction as described above is subject to many difficulties. It is weak, readily bent or distorte-d and when used in commercial bakeries gives a short life due to relatively rapid failure. Failure results from the bending of the top deck, the striking of various sets together and the usual wear and tear of dropping, washing and otherwise abusing the pans in the inevitable IIIHHIICI'.

I have found that if the top deck can be made strong and rigid that the strain on the individual pans is practically eliminated. I have found further that if the top deck can carry a pan or protecting member around its outer edge as disclosed on the drawing, the top deck is materially stifened and in addition when two sets of pans are forced into contact in the usual course of handling the outer edge-s receive the blow protecting the pans within. The outer edges, of course, are resilient and even a severe blow would only cause a slight dent or bending of the outer edge which would in no way affect the utility of the set of pans. On the other hand, if the outer edge member indicated by (4), (7), etc., or (l0), (11);etc., is not used, blows are delivered directly to deck member (2) and the tendency exists for the pans (3) to be loosened from deck member (2) which, of course, makes the set worthless. One of the Objects Of my invention, therefore, is to so construct the set of pans as to protect the individual pans, thus preventing them from becoming loose from deck member (2).

It will be apparent that I may use any dcsired material in constructing my set of pans, but I prefer to use ordinary commercial tin plate preferably of a heavy gauge. I may make the individual pans of the same gauge as the deck member (2) but ordinarily I prefer to make the deck member (2) somewhat heavier and more substantial than the individual pans.

I may turn the Outer edge which serves to resiliently protect the pans either upward or downward, but I prefer to turn it downward for the reason that the pans occupy less space, are easier to clean and receive greater protection when the edge member is turned downward. The circulation of furnace gases over the top of the pan is also more directv` thus permitting more uniform baking in the case in which the surrounding edges turn down.

It should be understood that I may make the individual pans which comprise the set of any desired shape or contour. Thus these pans may be circular, rectangular, etc., without departing from the spirit of my invention. It will also be understood that the depth of the surrounding edge may be varied as may also the minor details of construction. I may include any number of pans in a set and still come within the scope of this inven-v tion.

Having now fully described my invention what I claim as new and wish to secure by Letters Patent in the United States, is as follows:

l. In a set of baking pans a series of pans, a substantially horizontal deck portion uniting said pans and substantially surrounding and integral with a resilient downwardly turned edge member, provided with overlapping reinforced corner members, and around reinforcing bar attached to the lower portion of said edge member and outside of said edge member, and projecting beyond said set on all sides in a manner to provide resilient protection to said set.

2. In a set of baking pans a series of pans, a substantially horizontal deck portion uniting said pans and surrounded by and integral with a resilient edge member, interlocked, reinforced corners to said edges, and a reinforcing bar attached outside of the lower portion of said edge member, and eX- tending beyond the set in all directions.

3. A unit set of circular bake pans comprising unit pans attached to a substantially hori- Zontal deck portion, a resilient edge member formed in a single piece with said deck portion and downwardly inclined therefrom, interlocked reinforcing portions at each corner of said downwardly turned edge member, and a resilient reinforcing bar rolled into the lower portion of said downwardly turned edge member outside of said edge member, and projecting beyond the set on all sides.
