METAL DOOR.

Application filed October 5, 1922. Serial No. 592,484.

To all whom t may concern.'

Be it known that I, EDWARD J. ZAr-INER, a citizen oi the United States, residing at Laporte, in the county of Laporte and State ot Indiana, have invented certain new and useful Improvements in Metal Doors, oi' which the following is a specification.

The invention relates to metal doors, and has for its object to provide a door of this character wherein the opposite sides of the door are formed from single sheets ot metal stamped in such a manner as to form the opposite sides of the panel, the opposite sides ot the rails and the opposite sides ot the stiles.

A further object is to provide the panel adjacent the rails and stiles with inwardly struck tongues, which tongues form recesses for the reception ot tongues carried by moldings in such a manner that the outer tacings of the molding tongues are flush with the Also to construct the door in such a manner that it may be easily and quickly assembled and the parts spot welded, thereby obviating the use of rivets, bolts and the like.

vWith the above and other objects in view the invention resid-es in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment ot the invention may be made within the scope of what is claimed without departing` from the spirit of the invention.

In the drawing Figure 1 is a front elevation of the door.

Figure 2 is a ivertical transverse sectional view through the door, taken on line 2 2 of Figure l.

Figure 3 is a perspective view of a sheet or metal for forming one side of the door, showing the sheet before being bent to torm.

Figure 4 is a perspective view of one side of the door showing the saine after being formed. y

Figure 5' is a detail sectional view taken on line 5-5 of Figure 4.

Figure 6 is a detail perspective view of one corner of the door.

Figure 7 is a detail perspective view ot a portion ot the molding, showing one ot' the securing tongues carried thereby.

Figure 8 is a detail perspective sectional view through a portion of one ot the sides of the door, showing a portion ot' the 1nolding secured thereto.

Referring to the drawings, the numeral 1 designates a door, which door comprises a panel 2, stilles 3 and rails 4. The door is formed from sheet metal and the opposite sides thereolI 'from single sheets ot material similarly shaped, as shown in Figures 3 and 4. The sides 5 of the door are formed trom single sheets ot metal 6, which sheets are provided with extensions 4, which when the .sheets are bent at 7 to offset the portions 4 form the opposite sides of the rails 4 of the door, and longitudinally disposed portions 3a, which when bent at 8, form the opposite sides ot the stiles 3, said sides being ottset from the body ot the sheet 6. The sheet 6 is provided with interstices 9, which when the sheet is bent at 7 and 8 allow the ends ot the rail forming portions 4a, and the inner sides of the stile forming portions 3a to come into abutting engagement as clearly shown in Figure 4. Portions 4a eX- tend beyond the ends ot the portions 3a, therefore it will be seen that when the portions 4a are bent at their outer ends 4b, will be in alignment with the ends of the stile forming portions 3, shown in Figure 4. Secured to the inner sides ot the stile and rail forming portions, after the sides ot the door are formed, are plates 10, which plates are preferably secured by means oit spot welding the plates at 11 tol the portions 3a and 4, thereby rigidly forming the side of the door in suoli a manner that the abut ting edges will be in a close engagement so that after the door is painted, grained or enameled the joint will be invisible. During the stamping operation, the outer s ides et the stile forming portions 3a are bent downwardly at 3b, thereby forming lianges 12, which `flanges when the door sections 5 are placed in registration with each other extend inwardly and engage each other at 13, at which time a securing strip 14 is spot welded at 15 to the flange 12 tor securing the sides 5 ot the door together. The upper and lower ends ot the door so formed have disposed between the rail forming portions 4a and the stile forming portion 8a a channel member 16, the flanges 17 ot' which eX- tend outwardly and are spot welded at 18 to the rail 'forming portions 42L and the stile forming portions 3a. It will be seen that the body of the sheet 6 will form the panel 2 of the door and that the door is provided with an angle shoulder 18, preferably at a right angle to the panel 2 for the reception of a molding 19.

During the Stamping operation the sheet 6 forming the opposite sides 5 of the door are provided with elongated recesses 20 which are formed by striking inwardly tongues 21, which tongues are struck inwardly to a po* sition where their outer faces are in the same plane as the inner face of the sheet 6. The recesses 2() receive tongues 22, which are similarly Shaped and are carried by the molding 19 on the inner side thereof. The tongues 22 extend under the flange 23 of the molding 19 and upwardly in engagement with the inner side of the iiange 23 and is spot welded at 2A to the flange 23. It will be seenrthat when the molding 19 is applied to the opposite side of the door, that the tongues 22 will be received in the recesses 20. The tongues 22 are of substantially the Same thickness as the depth of the recesses 2O and of substantially the same size, therefore it will be seen that their outer faces will be flush with the outer faces of the panel 2 and that they may be easily and quickly spot welded at 25 tothe tongues 21. After the tongues 22 have been secured to the tongues 21, the door is finished in the usual manner, that is painted as a whole, grained or ena1n eled. By so connecting the molding it is obvious that the molding may be quickly attached and that by forming the tongues 22 of the same depth and size as the recesses 2O that after the door is painted or enameled the sides of the recesses will be invisible.

If so desired the molding 19 may be attached to the sides 5 forming the door before said sides are assembled.

From the above it will be seen that a metallic door is provided wherein the opposite sides thereof are formed from single sheets of metal, and the molding attached thereto in such a manner that the cost of manufacture is reduced to a minimum and that the dooi` may be quickly assembled, thereby reducing the cost of labor to a minimum.

The invention having' been set forth what is claimed as new and useful is 1. A metallic door comprising a panel, stiles and rails, the opposite sides of said door being formed from single sheets of metal, each sheet comprising substantially right angularly disposed offset portions forming the sides of the stiles and rails, said offset portions being formed by a bending operation as distinguished from a-drawing or stamping operation. n

2. A metallic door comprising a panel, Stiles and rails, said door having itsI opposite sides formed from single sheets of material having substantially right angularly form as distinguished from a stamping and drawing operation.

3. The combination with a metallic door comprising a panel, stiles and rails, said door being formed in two sections and from sheet metal, each section being provided with offset portions forming the opposite sides of the Stiles and rails, of a molding for said door formed independent of the door, said molding extending around the edge of the panel adjacent the stiles and rails, struck in members carried by the opposite sides of the panel and forming recesses, tongues carried by the inner side of the molding and adapted to be received in the recesses and extending beyond the inner edge of the molding.

1. The combination with a metallic door having a panel and offset rails and stiles forming shoulders around the panel, of a molding engaging the shoulders and the panel, tongues carried by the inner side of the molding and disposed within recesses of the panel and having their outer faces flush with the outer face of the panel.

5. The combination with a metallic door panel carried by offset portions forming rails and Stiles, said rails and Stiles forming shoulders around the panel, of means for securing a molding around the panel in engagement with the shoulders, said means comprising tongues carried by the inner side of the molding and disposed within recesses of the panel, said tongues being secured to the bottoms of said recesses and of substantially the same width as the recesses and having their outer faces flush with the outer face of the panel.

6. The combination with a metallic door panel and a molding, of means for securing Y EDVARD J. ZAHNER.
