METALLIC DOOR.

Specification of Letters Patent.

Application filed March 15, 1911.

Patented Jan. 9, 1912.

Serial No. 614,657.

To all whom it may concern:

Be it known that I, EVERETT N. GOULD, a citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented new and useful Improvements in Metallic Doors, of which the following is a specification.

This invention relates to metallic doors and to a method of manufacturing the same.

One of the objects of the invention is to provide a simple, inexpensive and thoroughly fire-proof door in which no rivets or other fastening devices are used to connect the separate parts together and whereln the welds will be concealed.

A further object of the invention is the provision of a door which may be con structed by first securing together the vertical and horizontal stiles, attaching the panels and necessary molding andfinally bending the door into shape and filling the space between its separated sides wlth a suitable refractory material.

A further object of the invention 1s the provision of a door of this character havlng its separate parts including the panels, top and bottom rails or stiles and the cross stiles welded together in such a manner that the blisters of the welds occur upon the inside so that a perfectly smooth door is produced which can be opened without grinding out and bufling the blisters after they occur upon the outside.

Further objects of the invention W-lll appear as the following specific description is read in connection with the accompanymg drawings, which form a part of this application, and in which Figure 1 is an elevation of the door. Flg. 2 is a longitudinal section on the line 22 of Fig. 1. Fig. 3 is a transverse section on the line 3-3 of Fig. 1. Fig. 4 is a transverse section showing the position of the door before being bent into shape. Fig. 5 is an enlarged detailed sectional view of the upper sill filler. Fig. 6 is an enlarged section of the lower stile and plllow.

Referring more particularly to the drawings, 1 and 2 represent the vertical stiles, 3 and 4 the top and bottom stiles respectively and 5 the cross stile. The stile 1 is constructed of separate sections 6 and 7 both of which are formed with lateral flanges 8 adapted to overlap each other when the parts of the stile l are brought together and at their opposite sides are provided with substantially L-shaped flanges 9, the legs 10 of which extend parallel to each other and in parallel lines with the sides of the stile. The stile 2 comprises a single strip of metal which is provided on opposite sides with L- shaped flanges 11 and 12 which, when the stile is bent into form as will hereinafter be described, are brought into similar relation to each other as are the L-shaped flanges of the stile 1. The stiles 3 and 4 are each constructed of separate sheets of metal having the L-shaped flanges 13 and a filler 14 which is substantially U-shaped in cross section and has its base or bottom seated in between the separate parts of the stile. The cross stile comprises separate members 15 and 16 each having L-shaped flanges 17. All of the stiles have their L-shaped flanges so constructed as to form abutting shoulders 18 for the metallic panels 19 which are secured to the flanges with their edges abutting the shoulders by means of spot welds, shown in dotted lines at 20. The filler member 14 for the upper stile is provided with inwardly projecting tongues or fingers 21 which are adapted to engage slots 22 in the inverted U-shaped filler 23, the sides of the latter member being sufliciently resilient to permit the same to snap over the fingers. The filler 14 of the lower stile closes the space which is formed between the panels and the sides of the stile members and the upper stile member closes the space at the upper end of the door. The space is preferably filled with asbestos or other similar refractory material 24, and a molding 25 is secured between the shoulders 18 and the panels. This molding may be secured in place by any suitable kind of fastening device or may be welded in place with an oxygen or acetylene torch.

In the manufacture of the device the top and bottom stiles are secured to the vertical stiles and the panel 19 spot welded to the flanges thereof while the stile 2 is in the position shown in Fig. 4. The molding is placed in position while the parts are as shown in Fig. 4 and the cross stile spot or torch welded into place. The stile 2 is then bent upon the lines 2728 which causes the flanges 8 of the sections 6 and 7 of the stile 1 to overlap each other. These flanges are then spot-welded together, and the filler 14 of the lower stile is then inserted and spot welded into position, with the blisters occurring upon the inside and the filler member 14 of the upper stile is also placed in position and has the blisters occurring upon the inside. Prior to the insertion of the filler for the upper stile the space between the sides of the door is filled with a refractory material. After the filler for the upper stile has been placed in position the inverted filler member is snapped into position and the door is completed.

Having thus described the invention, what I claim as new is 1. A method of constructing a metallic door which consists in forming one of the vertical stiles in two parts, forming the opposite stile of a single part, securing to the single part stile and to the parts of the twopart stile the cross stiles and panels and bending the single part stile so as to overlap the parts of the double part stile, and finally connecting the parts of said double part stile.

2. A method of forming a metallic door which consists in forming one of the stiles of separate parts, forming the opposite stile of a single part, securing panels and cross stiles to said vertical stiles, bending the sin gle part stile to bring the panels parallel with each other and to overlap the parts of the double part stile, and finally connecting the parts of the double part stile.

3. A method of forming a metallic door which consists in forming one of the stiles of separate parts, forming the opposite stile of a single part, securing panels and cross stiles to said vertical stiles, bending the single part stile to bring the panels parallel with each other and to overlap the parts of the double part stile, and finally connecting fillers in certain of the cross stiles.

4. A method of constructing a metallic door which consists in forming one of the vertical stiles of two members and the opposite stile of a single member, connecting said vertical stiles with cross stiles and panels by welding, the blister of which is arranged on the inside, bending said single part stile to bring the cross stiles and panels into parallel relation, and welding the parts of the double part stile together.

5. A method of constructing a metallic door which consists in forming one of the vertical stiles of two members and the opposite stile of a single member, connecting said vertical stiles with cross stiles and panels by welding, the blister of which is arranged on the inside, bending said single part stile to bring the cross stiles and panels into parallel relation, welding the parts of the double part stile together, filling the space formed between the stiles and panels with a refractory material, and securing filler members to hold the refractory material in place to close said space.

In testimony whereof I affix my signature in presence of two witnesses.
