MEANS FOR SECURING GLASS R MICA lN SHEET-METAL STRUCTURES.

CBPECIE'ICATION forming part of Letters Patent No. 325,523, dated September 1, 1885.

Application tiled December 2:2, 1884. (No model.)

.To aZZ whom it may concern:

Be it known that we, CHARLES A. Fnnronnn and WILLIAM H. WILDER, both of Gardner, in the county of Worcester and State of Mas- 5 sachusetts, have invented certain new and useful Improvements in Means for Securing Glass or Mica in Sheet-Metal Structures, of which the following is a full, clear, and exact'descrip tion.

Our invention has for its object the securing,

in a neat, cheap, and durable manner, of transparent or translucent material-such as glass or n1ica-in sheet metal, as, for instance, in stoves and lamps of various kinds having one or more glazed openings. It is more especially intended, however, for securing mica in the chimneys of oil-stoves.

The invention consists in a sheet-metal plate suitable for sheetmetal structures, having glazed openings, as described, formed with an opening through it, and provided on its back or inner face, alongside the marginal portions of the openings with a frame composed of open belts or hands united with the main portion of the plate by flexible lugs or projections, as hereinafter described, and forming a yielding receptacle for the glass or mica over the opening in the plate.

By the term open belts or bands is meant straps or strips which are separated along both of their longitudinal edges from the adjacent metal, so as to permit of the glass or mica passing freely through them and beyond the outside edges of them, thus distinguishing them from more pockets or lugs, and admitting of their being pressed down close on the glass or mica, or otherwise forming what may be termed a yielding frame for the glass or mica. These belts or bands, and the lugs which attach them to the main portion of the metal sheet, may be readily made by striking them up from the surface cf the sheet.

Reference is to be had to the accompanying drawings, forming part of this specification, 5 in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents an outside face view of a piece of sheet metal, which may be part of the chimney of anzoil-stove, constructed in accordance with the invention. Fig. 2 is a back or inside face view of the same with the mica or glazing material in its place. Fig. 3 is a transverse section on the line 00 w in Fig. 2; and Fig. 4 a transverse section in part, upon a larger scale, on the line 3 3 in Fig. 2. 5 5

A is the piece of sheet metal, having an opening, I), cut or struck out of it; also bands or bolts 0, struck from its outer surface along the marginal portions of the opening, and united at their ends or intermediately of their length with the adjacent portions of the sheet by lugs or projections d, that are struck up at the same time with the bands, and which, together with the bands, form integral portions of the sheet. These belts or bands are separated along both of their longitudinal edges from the main portion of the sheet, excepting where connected thereto by the lugs and inside t-hc intervening clips or pieces 6, formed from the metal sheet, for securing the side 7c edges of the glass or mica, and not only serve to receive the mica or glass 13, used to close the opening I), wholly through them and within the lugs, but form a yielding frame that may be pressed down upon the glass or mica to hold it in place; and where mica is used for the glazingof the opening in the sheet, the Whole may be bent together, if required-that is, when the sheet is designed to have a curved or other than flat shape.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- The sheet-metal plate A, having an opening, b, designed to be glazed, and provided on its back or inner face with a yielding frame composed of open belts or bands 0, arranged alongside of the marginal portions of said opening I), and flexible lugs or projections d, said belts or hands being connected beyond their outside margins with the metal of the plate contiguous to the opening by said flexible lugs or projections, but being detached therefrom along both of their longitudinal edges, excepting where connected by the lugs, substantially as and for the purposes herein set forth.
