Application filed May 26, 1909. Serial No. 498,400.

To all whom it may concern:

Be it known that I, CHARLES E. NELLIS, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Metallic Structures, Such as Doors and the Like, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to metallic structures, such as doors, frames, windows and panels.

Among the objects of my invention are the production of such a structure, which shall be attractive in appearance, strong and durable; relatively l1 ht in weight; economically manufactured quickly and accurately assembled, and whlch shall becapable of withstanding a high degree of heat and sudden changes in temperature.

Further objects of my invention will be hereinafter referred to, in the detailed description of a structure embodying'the same.

For the purpose ofbriefly and clearly describing my invention, I have selected for illustration and description, a metallic door embodying my invention in a preferred form; but it is to be understood that the invention is applicable to numerous structural parts besides doors and also that the particular details described, are susceptible of various modifications, not involving av departure from the invention.

Figure 1 of the drawings, is an elevation of a door embodying my invention; Fig. 2 is a vertical section on a larger scale, on the line 22, (Fig. 1) Fig. 3 is a sectional view of the structural parts unassembled, shown in Fig. 2; Fig. 4 is a sectional view on the line 44, (Fig. 1) Fig. 5 is a similar view on the line 5-5, (Fig. 1) and Fig. 6 is an unassembled view in section, of the parts shown in Fig. 5.

Similar reference characters are employed to designate like parts in all the views.

The articular structure illustrated comprises rame members, to wit: the

stiles

1 and 2, and the top, bottom and lock rails 3, 4 and 5, and the panels 7 and 8. The

stiles

1 and 2, and the rails 3, 4 and 5 are formed with

opposing walls

9 and 10, (Fig. 5), and are connecte by means of an interlocking joint which forms one of the features of my invention, and is illustrated in Figs. 5 and 6. I This 'oint is formed by bendin the edges of t e walls 9 of one member, preferably a stile), back upon itself, and again bendln or recurving them in asubstantially paralle plane'so as to form a slot or groove 11, of substantially the same width as the thickness of the metal, with a flange 12 projecting beyond the first bend.

reinforcing member 14, is secured to the flanges 12, either by riveting or welding it thereto, the extension of the flanges 12, permitting this to be accom lished with great facility, and without de acing the exterior of the structure. The edges of the other member, preferably a rail, are bent in a substantially similar manner, but without the slot 11, and the projecting flanges 15, of the second member are inserted into the slots 11 of the first member. The frame members are thus provided with shoulders 16 which abut against the shoulders on the other frame members when the flanges 15 are inserted into the slotsll, forming a flush joint between the members. If desired, in finishing the structure, this joint may be filled and suitably finished to present a smooth surface, entirely concealing the joint. The frame members may be further secured in position by rivets or by brazing or welding the joints.

It is essential, in doors and other structures of this character, that they should possess the capacity of withstanding a high degree of heat and extreme changes in temperature without buckling or becoming sufficiently distorted to separate or part from the frames. This is particularly true of the panel members, which from a heat-resisting standpoint, are the most vulnerable points of the structure. I therefore provide a yielding connection between the panel and frame members of the structure, which, while securing the necessary rigidity of construction, will permit a slight but suflicient relative movement of the members, due to expansion and contraction, under high or extreme changes in temperature. This feature of my invention is illustrated in Figs. 2, 3 and 4. The panel member 8, is preferably formed of two plates or sheets, which, adjacent to their edges are each formed with a double bend, similar to the bend formed in the frame members as hertofore described, providing if desired a molding-receiving slot or recess 20, and a shoulder 21. The

edges of each plate are projected beyond the shoulders 21, to form an extension :12, the extension of one plate resting against the extension of the opposite plate. If deslred, 6 these extensions may be rigidly secured together by riveting or wel i struction provides a dead air space 2i, between the two plates, which will largely prevent the conduction of heat between the 10 panel plates. A member 25, preferably of mverted channel form, fits tightly but slidingly between the walls of the.reinforc1ng member 26, secured to the flanges 29, of the frame members as above described. In the 1 form shown, the member 25, is provided with a recess 27, which receives the ends of the panel extensions 22. The latter are rigidly secured in place by riveting or otherwise. Thus the panels are supported in position rigidly against lateral movement but yieldingly with respect to any inward or outward movement of the edges due to contract-ion or expansion of the metal.

The slots or recesses 11, which I have described and shown as being formed in the

stiles

1 and 2, and as receiving the projectmg flanges formed on the rails, as will be understood extend the entire length of the stiles, and the inner edges of the walls of the rail members 3, 4 and 5 are bent to form similar slots 28, and flanges 29. The slots 11 on the stiles, and 28 on the rails thus extend completely around the panel spaces. Moldings 30, which surround the panels, are provided on each edge with

flanges

31 and 32. The flanges 31, extend into the slots 20, on the panels, and the flanges 32 into the

slots

11 and 28 on the stiles and rails respectively, the construction shown permitting the moldings to be inserted lengthwise during the assembling of the structure, and they are thus firmly held in position without other fastening means.

A structure of, the character described, embodying my invention, possesses reat rigidity owing to the reinforcement o the interior margins of the frame members, produced by the bending of the edges of the members back upon the sheet to form the abutting shoulders and flan e-receiving slots. Furthermore the different members of the structure can be assembled by comparatively unskilled labor with great facility and accuracy, and when completed, the structure presents smooth surfaces at all points, unmarred by any external fastening means, such as rivets, screws or bolts, for securing the moldings or the panel members to the frame. 50 In describing the manner of interlocking the stiles and rails, I have, to avoid prolixity, illustrated and described the slots as formed on the stiles, and-the cotiperating flanges as formed on the rails, but it will 55 of course be understood, that a mere reversal ng. This con- I of this arrangement would be within the scope of my invention.
