Application filed .Tune 11,1886.

metal shutter having a rigid frame produced' as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure l is aview of window, showing a pair of my shutters applied and one open and the other closed. Fig. 2 is a transverse section,and Fig. 3 a longitudinalseetion, in which the overlapping of the edges and metal straps to produce a rigid frame and the stays between the two walls are clearly shown.

A is the rear wall of the shutter, made of plain sheet metal. Its edges are turned at right angles in the manner sheetrnetal pans are made.

B B are stays, made of strips of sheet metal, that have their edges bent at right angles to produce flanges that rest dat againsttheinside face ofthe wall A, and are riveted fast thereto.

B are'pieces of wood, retained in place by means of the metal strips B, as shown in Fig. 3.

C is the front wall, preferably made of corrugated sheet metal. It corresponds in size and shape with the window to which it is to be applied, and is laid ilat upon the stays B and the projecting` edges ot' the rear wall, A, which edges are then doubled backward over the edge ofthe front wall, as clearly shown in Fig. 2.

D D are pieces of strap-iron, laid dat upon the turned-back edges and the overlapping portions of the two walls A and C, and riveted fast to prod uee a rigid border and frame around the complete shutter. The rivets are passed through all the overlapping parts and clamp the edges of the walls A and C and the strapiron firmly together.

F F are iron bars, that have pintles G extend Serial No. 204,879. (No model.)

ing downward at right angles from their ends, riveted fast to the opposite sides of the sh utters to re-enforce and brace them, and also to serve as parts of hinges, as clearly shown in Fig. l.

H represents a metal bar pivoted to the nside face of one of the shutters, to serve as a locking device for keeping the shutter closed.

A complete, strong, durable, and neat shutter is thus produced that will always have a voluminous air-chamber that will prevent fire on the outside of a building from heating the inside or back wall ofthe shutter, and consequently will be practically reproof.

I am aware that a plain sheet-metal wall having its edges turned at right angles has been combined with two corrugated walls by riveting the overlapping edges ofthe three walls together. I am also aware that metal straps have been riveted to the edge of a sheetmetal shutter; but my manner of turning the edges of one of the walls over the edge of the other wall, and then riveting metal straps thereto to cover the raw edge, and to produce a neat finish and a rigid durable framearonnd the edge of a shutter, is novel and greatly advantageous.

I claim as my invention- 1. The combination of a plain sheet-metal wall, A, having its edges turned at right angles and doubled backward, angular and tubular sheet-metal stays B, metal straps D, and bars F, having pintles G on their ends, substantially as shown and described, for the purposes stated.

2. The combination of the metal stays B andthe wooden blocks B with the Wall A, for the purposes stated.

3. The combination of the straps D with the wall C and the edge ot' the wall A, doubled over the edge of said wall O, for the purposes stated. v
