To all whom t may cof/wem: 1

Be it known that l, Eowi Gis'rnreon, n subject ol' the lling ot' Sweden, residing at Jamestown, in the county of Chautauqua and State of New York, have invented eertain new and nsetul lrnprorenn-:nts in Sheet- Metnl Door Construction, ot which the tollowing, teilten in connection with the accord penying dra wings, is a speeiliontion.

'lille invention relates to doorsl nidwindows inode ot' reet metal and the objects of lny improvement are Yto provide a hollow tuli 'hir f'znne which is rigid yet open and easy of access for the :fittaelnnentot' the hinges, latch, lool; and other hardware, .find

for the straightening ot' the sheet metal, :ind

to which the molding and panels n'niy he attnehed and all lthe parts securely drn wn to'- getlier hy ineens ol" snilnhle looking strips and interlocking lngs on the molding; und the inrention eonsists in tho eoinhinntion V:ind arrangement ol2 the ports ns shown in this specitieation and the nemnlpnnying drawings and pointed ont in the Claims.

Like numerals ot' reference retei 'to corresponding parte in the several views.

The numeral l() designates the. Stiles, the nnniernl ll the top or bottoni cross rails; and the ninneral l2 the middle eross rail ot' a door or window freine,

The stiles :nid cross rai-ils are preferably attached ,by nelding either with n initered joint as shown in dotted line in Fig. i or with a sti-night joint-across the end ot' the cross rnil .ll along the side oi the stile 1U ns shown in dotted line, ',lhe two ports of the ross rail l2 are also prel'erahly attached hy welding so as to t'orin a` rigid door or sash traine, the open construction on the inner edges permitting oli the stinightening of all' buckling or other liends in the sheet nietnl lroin riding or bending the stiles und Cross rails and also for nttnolnng the hardware.

llaeh ot' the siiles .lo 4and cross rziils ll are arranged on their inner edges with theopen space 1,13 formed by the two inwardlyv angulnr l'langes l-lon the edges of the sheet metal. binnlnr llnnges l-l; nre provided on the upper and lower edges oi the two ports of the iniddle cross rail l2 with n similar space lo therehi-tu'een. 'lheslot l-l admits to the door or sash ,traine so that latches, loolis, hinges and similar hordwnre een he :ittnehed to a door tranne before the insertion of the panels, and this construction also permits the coating ol' the interior of the tubular door freine to prevent rust and deterioration of the sheet metal. v The angular llanges lai. also stillen the lrzinie sind hold the parts ot the door together hy ineans ol a looking strip lo.

'The lorlting strip lo is pre'lernhly torined ot a single sheet of metal with angularlyllanged edges 16 lient the opposite ot' the angular flanged edges le: :ind spaced to lit within theni. A central tlnnge l? is formed hy a return bend in thesheet nieta-llplate, which tlange li' `extends out through the slot l3\\'lie1i.the parts are assembled. The. l'lnnge 1T has theslots 18 out therethrough with atongue 19 at one end. The flange il' also has theangular notch 20 opposite theniitered ends 21 of the cross locking strips,

llt)

said mitered ends resting preferably against the longer side of thenotch 20 to form a wedge when thelocking strip 15 is moved endwise it bears against the ends of said cross locking strips. Asheet metal panel 22 is preferably made of two sheet metal plates separated by suitable tire proof cement or asbestos packing 22 and fitting closely each side of the central Hangeor 'tongue 17 onlocking strip 15, as shown in Fig. 4.

Themoldings 23 and 24 for the opposite sides of the door may be made in any desir-edv pattern and rest against the inturnedflanges 14 and thepanel 22 on. each side. The moldings are made in the form of a frame as shown inFigs. 6 and 7 by being welded atthe corners, which frames fit withinthe Stiles and crossrails and are attached to thecentral flange 17 of lockingstrips 15 by means ofhooked lugs 25 and 26,hook 25 being att-'ached to the back of themolding 23 andhook 26 being attached within themolding 24, for a purpose in assembling which-will be hereinafter set forth. When it is desired to place a glass panel in the upper part of a door or to use my construction for a window sash, the moldings are modified slightly on their inner edges, themolding 23 being given areturn bend 27 alongside theglass 29 and themolding 24 being given anangular bend 28 along 'the side and edge of theglass 29. These two flanges27 and 28 abutting on one another' forma closed groove which ts the 'edge 4of the glass, rallowing for suitable packing.

' In assembling the door the frame is welded together, andthe hardware is attached within the frame and the frame is duly coated to' prevent deterioration' from condensation within the. tubular metal construction. The len" hwise and crosswise wedge strips 15 are t eninserted within theiianges 14 so that the angesl lit closely within theflanges 14 on all sides of a panel opening. Theentire strip 15 supports the sides of the Stiles and cross rails as they extend crosswise within the same, and thecentral iiange 17 extends vlengthwise throughspaces 13 on the Stiles and cross rails. 1

In a door, the wedge strips 15 would take the form shown in Fig. 11, the bevel end of the cross locking strips resting loosely against the lengthwise locking strips innotches 20. The hooked lugs 25 on molding frames 23 or 23 are then inserted through theslots 18 and thelugs 19 are pressed downward as shown 4in Figs. 2, 3, 4 and 14,

thereby pressing the hooked lugs 25 firmly against the inner side of. theslot 18 and holding themolding 23 or 23 firmly in place. Wvhen thepanel 22 is to be inserted withmolding 23, said panel is placed with the edge of theflange 17 inserted between the plates of the panel. The frame ofmolding 24 is then placed withitshooks 26 eXtending through the slots 1S from the opposite side of theflange 17 fromhooks 25 but with the hooked ends extending in the same di.- rection. rl`he lengthwise locking strips are then driven endwise thereby tightening all the parts .and locking the molding, panel, Stiles and cross rails firmly together.

The ends of the Stiles l() are preferably left open as shown at. 30 in Fig. 12, for the insertion of locking strips 15 through a hole opposite the end of the lockingstrip 15 in the door frame would serve the purpose since lockingstrip 15 may be inserted throughspace 13 and a tool is insertedthrough said hole to drive the wedge or locking strip into place. `Theopening 30 is closed in iinishing the door. The lengthwise wedge or locking strips on the opposite sides ofa door or window sash are prei"- erably arranged to drive in opposite directions so that they will draw more evenly upon the frame'.

It isapparent that this construction can be used interchangeably for either a door or window sash and that the door or sash can be taken apart for the insertion of new glass or lthe attachment of fresh hardware or any other purpose for which it may be desired since the locking strips can simply be driven back permitting the removal of themolding 24 or 24 and allowing the removal of themolding 23 and the locking strips 15.

I claim as new: 1. lAvdevice of the class described comprising a hollow sheet metal frame, oppositely placed molding for the two sides of said frame around the panels, intercrossing lugs on said oppositely placed molding to draw from both sides of said door, and locking strips engaging said lugs and frameto lock said parts together by end- `wise movementI from both ends of said door.

2. A-device of the class described coinprising a hollow sheet metal frame, oppositely placed molding for each side of the door around the panels,l oppositely movable lengthwise locking strips along the inneredges of the .st-iles having engagementwith said lugs to interlock the same, and crosswise locking strips along the inner edges of the cross rails engaging said intererossing lugs on the molding andl connecting to said lengthwise locking strips.

' 3. A device of the class described comprising a hollow sheet metal frame, inturned spaced iianges on the opposite edges of said hollow frame, a locking strip attached to said inturned edges, a tongue on said locking strip extending out between said spaced lflanges, a panel, molding for each side of said panel, and intercrossing lugs on said molding engaging said tongue and holding said parts.
