SHEET-METAL HEARTH-FENDER.

SPECIFICATION forming part of Letters Patent No. 619,863, dated February 21, 1899.

Application filed March 5 1 8 9 8.

To aZZ whom it may concern:

Be it known that I, FRANK G. CALDWELL, a citizen of the United States,residing at Wheeling, in the county of Ohio and State of West Virginia, have invented new and useful Improvements in Sheet-Metal Hearth-Fenders, of which the following is a specification.

This invention relates to sheet-metal fenders designed particularly for the hearths of fireplaces; and the chief objects of my invention are to economize in the expense of manufacturing such fenders, to avoid the attachment of separate front corner-pieces, to facilitate the formation of the desired contour of the front corners, and generally to improve and simplify the construction.

To accomplish these objects, my invention consists in the improved fireplace-fender hereinafter described and claimed, reference being made to the accompanying drawings, in which Figure 1 is a plan view of the sheet-metal blank from which the fender is produced. Fig. 2 is a perspective view of the shaped fender, showing one edge portion of each cut-out corner drawn over upon the opposite edge portion preparatory to riveting or securing the same and prior to turning in the outer edges to finish the article; and Fig. 3 is a perspective view of the finished fender.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring first to Fig. 1 of the drawings, which represents the blank from which the fender is produced. This blank is cut in a single piece from suitable sheet metal and is formed with parallel front and rear edge portions 1 and 2 and parallel end portions 3 and 4. The corner portions of the front edge of the blank are out out to provide V-shaped or angular spaces 5 and 6, having their edges 7 and 8 diverging from incisions 9 and 10 to the outer edges of the blank, the construction being such that the diverging edge portions 8 can be drawn over upon and made to overlap the edge portions 7, as clearly represented in Fig. 2, thereby producing the desired rounded contour of the front corners, which are embossed to produce ornamental corner-moldings without the necessity of attaching separate pieces and without the use of a tongue-piece extending Serial No. 672,729. (No model.)

down upon the corner portions and which requires to be secured at its opposite edges.

In my improved construction after the edge portions 8 have been drawn over upon and made to overlap the edge portions 7 they are each firmly and substantially secured through the medium of a single rivet 12, located near the outer edge of thefender, the inner por tion of the cut-out parts being firmly secured by molding or shaping the edge portions 8 with corrugations, as at 13, engaging similar corrugations on the edge portions 7. The sheet-metal blank represented in Fig. 1 is brought into the form of a fender, as represented in Fig. 2, through the medium of suitable dies, which mold or shape the single sheet of metal and leave projecting flanges 14 around the ends and front, which are subsequently turned inward against the inner sur face of the fender to produce a finished edge and a nice appearance, such turned-in flanges also constituting reinforcing and strengthening pieces for the end and front edges of the article. The fender is formed by the dies or molds with a dished top portion which inclines from the front downward toward the rear and extends from an elevated molding 15, running continuously around the fender.

The overlapping edges of the cut-out parts when the blank is composed of a single piece of sheet metal renders it possible to secure each overlapped portion by a single rivet 12, which is economical and advantageous over the attachment of separate corner-pieces and over that type of fenders wherein a pendent tongue integral with the blank is made to eX- tend down the corners and is secured at its opposite edges.

The overlapping of the cut-out parts is very advantageous over the well-known method of making a fender wherein the corner portions are crimped up to secure rounded contours, as such construction is difficult to make, and a smooth, nice, and finished appearance by merely crimping is not possible.

In my invention the overlapping edge portions of the V-shaped or cut-out parts can be easily embossed during the shaping or molding operation for the purpose of securing an ornamented rounded contour at each corner, which is very desirable in this class of articles.

I am aware that a hearth-fender has been made of sheet metal cut out at the corner portions to form separate triangular shaped pieces of metahwhich are subsequen tly placed upon and riveted to the body of the fender to provide corner-pieces therein. I am also aware that a bake-pan has been composed of a sheetmetal blank having triangular cut-out portions the edges of which are drawn over upon one another, so that one overlaps the other, the overlapping, parts being riveted together.

Having thus described my invention, what I claim is As an improved article of manufacture, the fireplace-fender herein described and shown, consisting of a single piece of sheet metal cut out at the corners to form V-shaped spaces, and having one edge portion of each cut-out FRANK G. CALDWELL.
