To all whom, t 'may concern: i

Be it known that l, JOHN W. RAP?, a piti; zen of the United States, and.- a resident of Flushing, borough of Queens, city and State of New York, have invented Tvcertain new and useful improvements in Mstal Doors and Similar Devices, of whichthe following is a specification. i

My invention relates to improvements in metal doors and similar devices and is espe eially well adapted for what are commonly known as doors of the hollori7 metal type.

in the accompanying drawings Figurelis s. front View of the top'pprtion of er door embodying the improved formof my invention, and partly broken away; Fig. H is a horizontal cross section on the line A-A of Fig. l; F ig. lll is an enlarged view in cross section of a top or bottom rail or stile; Fig. .lV the same as Figi lll, showing my preferred form of locking key inposition; F ig. V .is a horizontal cross section View on line lh-B of Fig. l;vFig. Vl illustrates my preferred method of securing a molding to a rail or stile and alsofor .retaining in position a panel; Fig. VH 'illustrates asimilar construction, but modified, to permit of the ready removal of the panel, and especially adapted wherel the panel is of glass or Aother material so readily destructihle, which it might be desired to move or change; 'Fig VIH is a cross sectionon the vline C-C `of Fig. 1X; Fig. iX. is a front view of a door embodying my invention in a modified form; Fig. X is a cross section on the line D-D of Fig. IX, and Fig. Xl is a' cross section on the line lil-#E of Fig. IX, where again the panel is Vshown to 'be of glass and easily removable.

ln these drawings similar reference characters designatecorresponding parts.

Referring now to the preferred form of my invention yillustrated inV these drawings, iii-H, designate the Stiles of the door, and J, J, the top and bottom rails. Obviously the construction of the top and' bottom rails is the same and the construction of the two" Stiles is the same, and the construetiodof the Stiles is the same as that of the top and bottom rails excepting 'at the junction point of a stilewith' a rail.

Each rail and each stile is preferably hollowl and substantially rectangular in cross section, having parallel side plates, an integral edge or end plate and provided at its inner edge with two lips or fdanges desig- ,Speeilcation of Letters Patent?

hated hik. the case of stiles and j-j in the case of top'--and,bottom rails. The lips or Aflanges are alsofpreferably integral with and arranged to project from cross plates or inwardly bent'portions integral with side platesand extending toward `each other so as to bridge a part of the distanee between the side plates, and to provide a slot or groove .in the lengthwise edge' opposite to the outer edge or. end plate/'of the rail or stile. In the case of the stil'es these projecting lips .li-7L" are used in" conjunction with a key to secure a molding to the inner edge of the Stiles, and also to eli'ect the junction between the Stiles and the top and bottom rails. For example, as illustrated in Fig. 11,-the lips or flanges h-t of the stile H are inserted between the inwardly projecting lips or flanges 7.--c of a ymolding K.

' M designates what l call a key, shown as made of one piece of metal bent to form a back plate, m, and two tongues m1 projecting therefrom, and bent over and backward at their outer ends to form securing clips m2 m2. l

The lips or flanges t-c of the molding K having been .slipped over the lips or flanges L-L of the stile H, and arranged to the desired position, my key M is then inserted as indicated in Figs. Il and IV with the tongues m1-m1 intermediate the flanges or lips L-L of the stile H, with the back plate min Contact with the inner surface ofthe inner end of the stile, and with the bent over rretainng clips fm2-m2 of the key surrounding and in contact with the 'ilanges or lips /r-: of the molding K. This key is then driven in any suitable manner throughout the length of the stile or at least throughout that portion of the stile to which it is desired to secure a molding. The molding is secured to the top and bottom rails in a precisely similar manner. y

Fig. V illustrates my preferred method of `securing the stiles and rails together, y where the flanges or lips laf-71. on the inner edge of the stile continue throughout the entire length of the. latter` and the key M i2-ff, between which are inserted the out Wardly projecting lips or anges t-h of the vstile H. The key K is then inserted in 16 n peil l'llll'lCel the same manner as already described with regard to Fig. II and driven through first to secure one rail to the stile, and second to secure themolding to the stile, and finally to secure they other'. rail to thestile.` As the f molding has already been secured to the inner' edge ofthe top and bottom rails and cut at the corners `at thev desired angle, the molding on the rails will be forced into proper position with regard to the molding of the stiles as the key is driven'home. The corners of the molding may then be welded together by electric weldingor any other suitable method, or be 'treated in any other way to give a smooth and finished apthe stile, if the saine, has been left open to permitl 'of the driving of the key, or if hole haslbeen "made or left for this' purpose`,'tl'ie same may be closed by'welding a piece of metal over thevsameeorinany other f Lsuitable manner.

ranged withinv the groove Kleef a molding K. As the metal of the' molding is` preferably rather thin and resilientthe.driving home of the keyM` should result in the lpanel being gripped rby-tlienvalls of the groove K1. .i f.

IVhereglass or` other destructible mate. rial is used as the panel or where for any other reason it may be necessary or desirf kable to make the panel removable, I prefer to 'use a construction suchas is illustrated in I Fig.v VII, wliicliis the same in all respects as that illustrated in Figs.. II and VI with the exception that themolding is bent to formonlv one side and the back wall of the groove K1 integral `with thegmolding. ,The

other side wall of the groove is `formed of H a separate piece ofinetal designated in Fig.

VII byc5 and removablyfsecured,to'the rest of the molding inany suitable manner `as'by a screw Z.. i

In Figs. VIIIf- IXf-X and XI, I have .illustrated what maybe called an inversion vorreversal of tliecoustruction and nietliod emplovedin the figures so far described.' Fig. VIII shows the joining of arail to astile where the lips or aiige's yt-y2 of the rail .I project outwardly and those lr-4h of the stile Il proiect inwardly, and 'where the key has vits backm rarranged within the rail yand. its securing clips project? 'lng into the Vinterior 0f the stile.

Figs. andXI illustrate respectively the'invei'ted method ofsecuringa moldingand a'non After theparts'have been secured in place as already described, a top plate may be welded Vover the open end of removable panel (Fig. X) and a removable panel such as glass Fig. XI). In these figures the stile H has its lips or flangesi-h projecting inwardly, whereas the lips ork flanges iti-lc kof the molding K project outwardly. Obviously the'key M is inserted as described with regard to Fig. VIII, and then driven down throughout the length of the stile to secure Athe top and bottoni rail and the molding and the various panels thereto. This inverted form is peculiarly adapted to cases where the molding is small or where there is' vinsuflicient space in the molding to permit of the ready insertion of the 'tongues and securing clips of the key.

If intermediate rails, such as those designated J1 and J2 ofAFig. IX are used, their ends are provided with lips or flanges pro jecting either inwardly or outwardly, and secured in the saine manner as the top `and bottom rails.y
