SHEET-METAL PAN.

SPECIFICATION forming part of Letters Patent No. 224,396, dated February I0, 1880.

- Application filed October 20, 1879.

' in the county of Suffolk and State of Massachusetts, have invented a new and Improved Sheet-Metal Pan, of which the following is a specification. V

Figure 1 is a p1an view,representinga sheet of metal cut in proper shape for the construction of the pan. Fig. 2 is a longitudinal sectional view, representing the second step in the construction of the pan, wherein the edges of the plate are once folded over and the ring is put in position. Fig. 3 is alongitudinalsectional view, representing the third step in the constructiomwherein the edges of the plate are still further folded over. Fig. 4 is a 10ngitudinal sectional elevation of a completed pan. Fig. 5 is a plan of the ring and its ear; Fig. 6 is an end elevation of the pan.

The invention consists in a sheet-metal pan with flat bottom, flatfolded edges, a ring, and an ear. as hereinafter described.

In the drawings, Ai-epresents the octagonal blank or sheet of metal. (Shown flatin Fig. 1.) In Fig. 2 the edges or. of the sheetAare shown folded over upon the surface of the said sheet, and the ring B is shown attachedto the said sheet A by means of the insertion of the ear b under a fold, a. In Fig. 3 it is shown that another bend, c, in made in the edge of the com.- pleted part.

In Fig. 4 the completed pan is represented, in which A is the bottom; 0, the sides; a, the folded edge; 0, the inner bend of the edge; B, the ring, and b the ear holding the said ring B to the pan. Itis found that this folded edge e is stiffer than the ordinary wired pan-edges are, and is much cheaper of construction; and it is also found that the ring B is securely held to the pan by the binding or folding of the ear I) in the folded edge 0.

In Fig. 6 the corners g are shown. impart strength and stiffness to the pan.

The corners are first cut from the sheet of metal to form the blank A; next the edges of the blanks are folded over, and the ear I), with ring B, is inserted under one of the folds thirdly, the folded edges are turned up at right angles to the body of the blank, so as to bend the ear b in the fold; fourthly, the sheet is reversed and struck up with a (lie into the form shown in Fig. 4 of the drawings; lastly, the corners g are folded down, as shown in Fig. 6.

This pan then, thus constructed without rivets, wire, or solder, and having its ring secured to it without the use of rivet or solder, has

They

edges as strong and as durable as the ordinary wire-edged pan, is of somewhat less weight, is

more convenient in use, because its broad flat edges afford a good hold in putting it in or out of an oven, and can be manufactured at a greatly reduced cost of material, time, and labor. V Having thus fully described my invention, I claim as new and desire to secure by Letters Pateut-- As an improved article of manufacture, the sheet-metal pan herein described, having a flat bottom, flat folded edges a, folded corners g, and ring and ear B b, substantially as set forth.
