A TTORNEY brrn s'tra'rns PATENT ormcn CARL G. DANIELSON, OF KANSAS CITY, MISSOURI.

METALLIC DOOR.

Application filed December 21, 1911.

To o/t 207mm 175 may concern:

lie it known that I, CARL G. DANIELSON, a citizen oi the United States, residing at Kansas City, in the county of Jackson and State o't hlissouri, have invented certain new and useful lmprovcn'ients in .lletallic Doors, ot which the following is a specitication.

lily invention relates to improven'ients in .ll'ltijtlill04l00l'8, and the like, and one object of the invention is to provide a novel ll1()l(l ing whereby the panels may be firmly se cured to the stiles and rails of a door without welding or en'u'iloving rivets; thus inaterially reducing the cost of construction without sacrificing strength or other desirable features of a door of this character.

My improved molding is made separate from the stiles and rails, and embodies grooves for the margins oi the panels and locking members adapted to be readily slid into engagement with corresponding locking members on the stiles and rails, to reliably secure the panels thereto.

Other objects of the invention will hereinatte' appear and in order that said invention may be fully understood, reference will now be made to the accompanying drawing, in which:

Figure 1 is an elevation partly in section of my improved door. Fig. 2 is an enlarged section on line II TI of Fig. 1, and Fig. 3 is a section of a modified form of the invention.

1 designates the hollow stiles, 2 the hollow rails, and 3 the panels of the improved door. Panels 3 are reliably secured to stiles 1 and rails 2 by molding st, forming an important feature of the invention. iilolding 4- is cut into sections of proper length, which sections have lnitered meeting ends 5, as shown in Fig. 1. Each section comprises one piece of sheet metal having a central longitudinal groove (3, to receive the adjacent margin of a panel 3, as shown in Fig. 2. Groove (3 is formed by a central transverse wall 7 and two parallel walls 8, which latter are bent at right-angles to the former and spaced apart to admit the panel 3. The parallel walls 8 are bent at right-angles in opposite directions to each other to form walls 9, bent to form walls 10, which are parallel with walls 8 and bent to form curved walls 11, communicating with walls 12, bent inward toward each other to form a pair of 10cking-members 18, which terminate adja- Specification of Letters latent.

cent wall 7. Lockirig-members 13 are adapted to slide longitiu'linally into sockets formed by loeking-men'ibers arranged in pairs on the stiles 1 and rails 2. Said pairs of lockingmembers are alike, and each pair is preterably formed integral with the inner side of its respective stile or rail. The inner ends of said locking l'nembers are in juxtaposition to walls 8 to prevent lateral movement thereof.

Referring to Fig. 2, it will be seen that each pair ol locking-members comprises two oppositclyalisposed flanges 11 and two flanges 15, communicating at their inner ends and spaced apart to form sockets 16, adapted to receive the lockingmembers 13 on the molding. l langes 15 extend at rightanglcs to the side walls 17 of rail 2, which is stitl'ened by a transverse reinforcing member 18, hearing against flanges 15 and wall 7 to stitl'en the same. The opposite edge of the rail is closed by a metallic-plate 19, the ends 20 of which are bent at right angles thereto and have longitudinal beads 21, to engage (.orrespomlin; resilient clampingmembers 22 on a transverse reinforcing plate 23 paralleling plate 18 and secured to walls 17.

The rear edge of the door is reinforced by a metallic bar 2-1, having recesses 25 to receive the hinges (not shown) whereby the door is hung.

In the form shown on Fig. 3. the molding is substantially the same shape as that shown on Fig. 2, except that it is made in two pieces. one of which is held in place by screws 26, so that it can be readily removed should the glass panel 3 become broken. A cushion 27 is provided to permit the metal portions of the door to expand and contract without fracturing the glass panel.

\Vhen the rails, stiles, and panels are connected as above described, a very rigid and durable door is obtained.

lVindow sashes and other like articles can be constructed according to this invention, as the drawing forming part oi this specification only intended to illustrate the invention in a rern'esentative way in connection with a metallic-door.

Having thus described my invention what I claim and desire to secure by Letters Patent, is:

A metallic door, or the like, consisting of panels, hollow stiles and hollow rails. each stile and rail consisting of a pair of side deli 1,U823,071

thereof, and a reinforcing" member connec ing the W115 oi each stile and rail and abutting against the looking members thereof and the inner Wall of a groove, substantiaily as shown and described.

in testimony whereof i my signature, in the presence of two wltnesses.
