March The present invention relates "to cracker pans and other such like devices, and has for 7 its primaryobject to provide an improved frame structure for such devices which will enhance the durability of'the device, cheapen its construction, and otherwise improve the same. For the purpose of illustrating the salient features of the invention, two embodiments are shown'in the accompanying drawings in which Fig. '1 is a plan View of the preferred embodiment; I T

Fig; 5 is a longitudinal section on the line 55 of Fig. 4 looking in the direction of the arrows; and

Fig. 6 is an enlarged detail view, in section, of a. modified form of the frame joint.

Referring now to the drawings in detail, the cracker pan comprises a supporting surface 5, preferably made from wire mesh, screen, orvmesh cloth, with a frame 6 for stretching the cloth, binding its edges and reinforcing the same. The present invention is concerned with the frame structure and according to the preferred form, as illustrated in Figs. 1 to 3, inclusive, the frame is constructed of a plurality of elbow sections, each comprising a folded U-shaped band iron out and bent into the proper form and adapted to be joined together to make up the frame.

The edges of the wire mesh 5 are confined between the folds 7 and 8 of the U-shaped band irons and rivets 9 are employed to anchor the screen between the folds. These rivets pass through the folds 7 and 8 and throughthe mesh of the screen.

In order that the pan may be slid or otherwise moved over a supporting surface, or in fact over any surface, it is desirable that the faces 7 on each section of the frame on one side of the pan be flush with the faces on ad- 1927. Serial no, 172,431,

also preferred for the "oppositeside of the I pan in connection with the faces 8. To'this end the joints between the sections are flush and'not even the headsof the rivets 19 project above the faces,the same being countersunk in the faces for this purposer so far as concerns thepreferredform of joint; shown in Figs. I to 3, inclusive,l arrange the ends of the sections-in abutting or at least confronting relation to one another as at 10 and to reinferce the joint, reinforcing members 11 and 12 are insertedbetween the folds? and 8 at the joint the member 11, for instance, overlylng the screen 5 onione side and the member 12 overl in the screen on the opposite sides The members 11 and 12 preferably comprise metal strips of a width equal to th'at'of the width of the foldsof the sections and wheninserted, as described, they v may be anchored by the rivets 9 passing through'the folds of the sections, the members themselves, and'the wire screen 5. In this construction the joints are properly reinforced and the sections rigidly heldtor gether with their faces flush. The joints are preferably made to occur at the sidesand ends ofthe frame so that the corners of the structure are not weakened by the joints.

Practically the same advantages so far as rigidity and reinforcement is concerned may beaccomplished by the modified form of the invention shown in Figs. 4 to 6, inclusive. In this forma so -called telescopic joint is provided by inserting the end of one section 6.

between the folds of" an adjacent section, the

screen 5 in this form having its edges bound between the folds of the framese'ctions as in T' the other form referred to. Itivets 9 ers used in this-forminthe same capacity as in the preferred form and their, heads are countersunkinthe faces of the folds To realize a continuous fiushface the opposite sides of the pan-in this telescopic form vo'f joint, I compress thefolds to a smaller dimensic-nfon the inserted section so as to compensate for the thickness of each fold on the outside section. This provides the countersunk portion clearly shown as at 13, The rivetsl9f are preferably arrangedv sothat at least two rivets are to be provided for each joint at the ends of the telescoping sections. The frame sections 6 are also made as elbows, so to speak, so that the joints will the more or less rough usage that cracker.

pans are usually subjected to, the edges of the wire screen tend to become loosened from the outer frame to which the wire screen is secured. However, by providing a U-shaped metal band to constitute th'e'oute'r securing framethe endsofthe Wires cannot project from the frame into positions where such wire' ends'mightinjure the hands of the users. it should also be noted that the joints are intermediate the corners and therefore the corners of the frames may be kept in stock with the legs of varying lengths so that cracker pans of varying sizes, as de-. sired, may be quickly and readilymade by cutting the wire screen of the desired shape and sizeand thenselecting from stock the corner frames with legs of lengths to fit the scre-ens'that have been cut. Therefore by I means'o'f the. construction shown and-described thecorner's and edges of thecracker pan will always present smooth surfaces to he hands of the users and; at the same time the frame will be strong and durable, the joints being reinforced, as shown, for both forms. In other words, by properly reinforcing the joints and providing, integral corner frames a cracker pan is provided which is strong and durable and maybe subjected to hard usage withoutbecoming distorted and without displacing any of the ends of the wires into any positions where they would come into contact with the hands of the users. Furthermore,thereinforcements at the joints and the means of securing the frame sections to each other and to the wire screen are such as to provide flushsurfaces topermit the cracker panto slide'freely over the oven floor and other'surfaces on which the cracker pan is placed and moved about. It will also be seen that the construction is such as to necessitate a minimum amount of material, therebylessening the cost of-construc'tion and 'lighteningthe same to facilitate its use without sacrificing strength and durabilityl precise construction herein disclosed.

Having thus described and shown embodiments of my invention, I desire to secure the following by Letters Patent of the United States: I V

1. A cracker pan embodying in its construction a wire screen and a frame therefor, said frame comprising a plurality of frame sections each U-shaped in cross-section and L-shaped in plan, means confining the cut edge of the wire screen'between the folds of the frame sections so as not to be exposed, means comprising strip 'members inserted between thefolds on opposite sides of the wires'cre en between the corners of the frame to form reinforced joints between the adjacent ends of the saidframe' sections, and rivets passing through the folds to permanently secure the wire screen to the frame and permanently secure said strip member at the joints,

2. A cracker pan embodying inits, construction a wire' screen and a frame therefor, said frame comprising a plurality-of. elbow sectionseach U=-shaped in cross-section to forminwardly extending grooves to receive the peripheral edge portion of saidwire screen while the latter remains in a single plane, and means comprising 'pairsof plates within said grooves on opposite sides of the lire screen for securing the elbow sections together with their exposed faces flush with one another. 1

In testimony whereof I have signed my name to this specification on this28th day of February, A. D. 1927.

JOSEPH GEORGE J ACKS'ON.
