lETAL DOOR.

Application filed June 1G, 1921.

To all wiz/0m t may concern:

Be it known that I, ANDREW J. CONNELL, a citizen of the United States, residing at College Point, county olf Queens, city and State of New York, have invented new and useful Improvements inMetal Doors, of which thefollowing is a specification.

This invention relates te metal doors and Y more particularly to frame-members for such doors. Y

The principal object of the invention is to provide a simple and durable metal door of economical construction and comprising Y metal plates, a frame-member comprising a Y of oneform of Vbody-portion having integral therewith a molding to engage said panel, and means for holding the panel and molding in engagement. r The invention is illustrated in the accompanying drawings in Which- Figure 1 is a perspective view of a section panel with its cooperating frame-member Figure 2 is a view similar to Figure l, showing the relation of parts before the vframe-member has been attached to the panel;

portions 12 and within the channel 13.

members 2, 4, 5 and 6 are all ramewmembers of the type shown in detail in the other figures. y

Figs. l and 2 show a section of such a ra1nemember which comprises a channel shaped body portion 7 the margins 8 of which are inwardly turned to form molding portions to engage the panel 9. While the molding portions 8 might be curved continuously or in any other suitable manner, they are most desirably provided with steps 9, 10 and 11`so as to result in a molding of ornamental appearance.

In the embodiment shown in these figures in whichthe framednember cooperates with a panel formed of a single thickness of sheet metal, V'the edge portions 12 of the molding are preferably down Vturned and spaced apart a distance slightly greater than the thickness ofthe panel to be engaged. Thus in assembling a. complete door the frameniembers areV placed one at a time in the positions shown in Figure 4 after which a channel-member 13 of a size just sulicient to slide'easily over the outer surface of the edge portions 12 is set in place as shown in Figure 2. The vupper edges 14 of the channel 13 are then pressed inwardly so as to iirmly lock the Ypanel 9 between the edge ln assembling a complete door it is customary to apply the frame-members 2, 4, and 6 in the order named. For doors of considerable size the 'E ame-member, consisting merely of the body portion 7 and molding 8, will not have suiiicient strength, in which;

case an inverted metal channel 15 is most desirably set between opposite walls ci the body portion abutting the underside of the steps 9 and welded in place by spot welds suitable distances lapart as at 16 and 1T.

The construction shown in Fig. 3 is that of a frame-member designed in accordance with this invention to cooperate with a panel which comprises the two plates 19 and 20, between which there is inserted a filling 21 of sound or heat insulating material, such as asbestos or other suitable substance. To accommodate a panel of this type the margins 8 ot the cliannehmember, comprising the body portion 7, are inwardly turned, as in the construction previously described, with the exception that the edge portions 12 are now given a final upward turn so as to provide a seat between each step 11 and said edge 12. The plates 19 and 2O are set in their Vrespective seats after which a metal strip 22, which fits snugly between the inner surfaces of the edge portions 12, is inserted and the i'rame-men'iber is then permanently joined to the plates 19 and 2() by spotwelding just above the step 11, as at 23. The filling 21 may be inserted before the panel is attached to the molding and may be tight-ly packed against the strip 22 a'lftei' one unit ot' the frame work has been attached to the panel, and will bel lirnily held in place by all such strips in the completed dooixr` In doors having the insulating panel such as shown in Fig. 3 it is almost impe 'ative to reinforce the body portion 7 of the frame-member by a channel 15, which may be welded in place as was previously described. In doors of this type it is usual to provide sheets of insulating material 2a coextensive with the side walls or' the body portion 7 of each frame-member. To hold these sheets 24 in place there is provided a U-shaped spring-member 25, the upper edges of which may be compressed while the spring is inserted into the body portion after the sheets are set in place, and upon releasing the edges the spring 25 holds the sheets permanently in position.

From the foregoing description it will be apparent that' this invention provides a frame-member for metal doors which mayV be employed' as either a rail or stile in connection lwith panels or" any desired type, which may be quickly and easily set in place and lirmly and permanently secured. The

frame-member being made of a continuous sheet of metal cannot become loose ii'liiie the door is in use and being secured either by a locking member, or being welded, cannot become detached `lroin the panel.

While have shown and described one ifi-sabes particular embodiment of .the invention in great detail, it is to be understood that I do not limit myself to the precise form shown, but reserve the rights to all modifications coming Within the scope of the appended claims.

`What I claim is: Y

1. A metal door or like structure embodying, in combination, a frame member comprising a single piecev of sheetV metal bent to provide a substantially channel-shaped Vbody portion, integral molding portions and portions disposed in substantially the plane of the side walls of the body portion and also being further bent to provide portions extending towai'd the center line oi' the said body portion at substantially a right angle to the said sidewalls, said inwardly and centrally disposed portions forming Ythe sides and bottom of" a panel socket; and a panel seated in said socket;

2. A metal door or like structure embodying, in combination a :trame member com` prismg a single piece of sheet metal bent to provide a substantially-ohannel shaped body portion, integral molding portions and por tionsdisposed inwardly in substantially the Y plane-ofthe side walls of: the body portion and also being further bent to provide-portions eiitending toward the center line of the said-bodyportion andA also having portions extending outwardly in substantial parallelism. with the said inwardly disposed portion to Vform. oppositely disposed panel sockets; and panel plates seated in each of said sockets. Y

3.V fr metal` door or like structure embodyingin combination, a panel Vanda frame member comprising a substantiallychannelshapedvv body portion, a lining oiEV {ire-proof material arranged to. abut against oppositeV `sides of said frame member and a U-shaped spring retainer for holding the opposite sheets of; lireprooi lining in place'against the said opposite side walls of said body portion.
