2 Clams. (Cl. 189-53) My invention relates to hinged doors for stores, ofiice building entrances and the like, and more particularly to doors made up of 'glass panels in extruded metallic frames.

It is a purpose of my invention to provide to strengthen and structurally simplify the frames for hinged doors with glass panels, so as to not only reduce the cost of manufacture thereof, but to minimize the mode of assembly of the parts of a door frame in relation to each other and to the'glass panel which it contains, and while 'effectively securing the panel therein, also allows ready removal thereof should it become broken to substitute a new panel.

It is also a purpose of my invention to provide a door frame including a sectional rail, which affords means for mounting on one of its Vertical edges hinges by which the door is hung in a doorway, and ,a second rail on its other Vertical edge which is detachable to allow rails of different forms to heV used depending uponl whether the door is hung to swing in one or two directions, and whether it is hung from one vertical edge, or hingedly mounted on the floor to swing in both directions for use in conjunction with a similarly mounted door to provide a two door Controlled entrance for stores and the like.

I will describe only two forms of doors, and various forms of jamb rails, each embodying my invention, and will then point out the novel features thereof in claims.

In the accompanying drawings:

Fig. 5 is a view similar to Fig. 1 showing another form of door embodying my invention.

Fig. `6 is an enlarged fragmentary elevational view of the door shown in Fig. 5.

Fig. 7 is a transverse sectional view taken on the line 1-1 of Fig. 6.

Fig. 8 is a fragmentary horizontal sectional view showing my invention embodied in a pair of doors mounted to swing to open position in one and the same direction.

Having specific reference to Figs. l to 4`,;my invention in this embodiment comprises a door D composed of a glass panel P in an extruded metal frame of .rectangular form and designated generally at F.V The door D is of that type which is hung from one Vertical edge in a doorway W by hinges H and to swing to open position in one 'direction only.

The door frame F is composed of top and bottom or end Sections [5 and IB, and side or vertical sections ll' and' l'8, and all sections are of identical construction. I-Ience, a description of the structure of one section will sufilce for all. Each frame section as aforesaid is of extruded metal construction,`preferably aluminum, and so made as to form an elongated body IS of hollow rectangular form in cross-section. The inner end wall 20 of the section is relatively thick, and its outer side is formed with a- Vdove-tail groove 2| adjacent one side of the section, which is coextensive in length with the section. Adjacent the other'side of the section the wall 20 is formed with a' right-angled groove 22 in spaced parallelism to the groove 2| and likewise coextensive in length with' the wall 20. The other end wall 23 of each frame section is formed on its outer side with a dove-tail groove 24 which is made as wide as the section will permit, and coextensive in length with the section.

A pair of retaining strips S and SI, likewise o'f extruded metal, are carried by the wall 2D of each frame section, and the strips of all of the Sections coact to secure the panel P within the frame F. The strip S may comprise a fiat portion 25 of a width to span the entrance edge of the groove 2|, and this portion is formed on its outer face with a doVe-tail tongue 26 coextensive in length With the strip and insertable into the groove 2| at either end of the section. The strip S includes also a second portion 21 divergent in relation to the portion 25 and terminating at its free longitudinal edge in. an angular lip 28 coextensive in length therewith.

The strip SI is of similar construction to that of the strip S. VVIts portion 21a is divergent to the flat portion 25a, and the'lip 28a is parallel to the lip 28 of the strip S. The tongue 26a on the portion 25a,'a1though doVe-tailed and of the. same dimensions as the tongue 26, is readily insertable laterallyinto and removable from the groove 22 because it is of right-angle form and of a width to accommodate the tongue.

This construction allows the strip SI to be mounted on theframe section by moving it laterally against the, section whichis in contradistinction to the stripl S which requires it to be mounted endwise on the frame section because of the dove-tail form' of the groove 2|. With the two strips mounted on the frame section they coact to form a fan-tail channel 29, the lips 28 and 28a being spaced to accommodate therebetween one marginal edge of the panel P, and the panel edgesecured' inV positionby filling -thel channel With putty, cement or, anyother suitable material 30 (see Fig. 3).

The strip SI, ,onceV applied as described, mayextended 3 provided and secured in place and the channel 29 filled with putty with retaining strips S and SI, it will be clear that all four edges of the panel P are fiXedly secured to the frame sections to form a complete door. Inasmuch as the strips SI are detachable from the frame sections by first removing the screws 3| and then loosening the putty, the panel can be easily removed from the frame without disturbing the strips S, to permit substitution of another panel should it become cracked or broken.

To secure the Sections of the frame F in rectangular form prior to placing the panel P therein, conventional tie-bolts B are extendect longitudinally through the top and bottom sections 15 and IG, `with the ends of each bolt passing through plates 22 fitted in the opposite ends of the frame Sections. As shown in Fig. 4 each plate is formed on one face with a dove-tail tongue 33 and a right-angled tongue 34, these tongues corresponding to the tongues 26 and 26a of the retaining strips S and SI, and, hence, are extendable into the grooves 2| and 22. Thus the tongue 33 serves to hold the plate 32 on the frame section 11, but to secure the plate to the frame section andagainst possible twisting of vthe sections 15 and H relatively, the tie-bolt B is eX- tended throughthe plate and the nut 35 screwed home on the bolt. With such connections at all four corners of the frame, it is manifest that the frame Sections once assembled provide a non-twistable or otherwise distortable frame.

The groove 2d in the Vertical frame section I'I receives endwise a pair of ribs which coact to form a dove-tail tongue 36 on one face of a rail R for securing the vlatter to the edge of the frame section. It is upon this frame edge that the door D is hung by the hinges H, the latter being constructed to allow the door to swing only outwardly of the doorway. The hinges are secured directly to the frame section l'l by screws 37 threaded in the wall 23, and to permit this the rail R is made in Sections With one leaf of the hinges between the Sections and abutting the ends thereof so that the latter aid in supporting the leaves on the door frame. The other leaf 38 of each hinge is. screwed to the adjacent jamb 39 of the doorway, and thusthe door is hung in the doorway.

The groove 24 lin therframev section IB receives lengthwise a pair of ribs 49 which coact to form a dove-tail tongue on the inner side of a rail RI. Thisrail, as well as the rail R, mayI be termed a jamb rail in that it faoes the other jamb 4| of the doorway. The rail RI ymay' be made of any contour on its outer side depending upon the cross-sectional contour of the jamb 4|. As the jamb vis beveled transversely the side of the R1 is likewise beveled.

Referring now to Figs. 5, 6, and 7, I have here shown a door DI which is mounted on the floor 42 and the upper joint' 43 of a doorway WI to a store or the like, by conventional hinges I-Il to swing inwardly and outwardly through the doorway. While the construction of the door frame FI thereof is Substantially the same as the frame F, the frame Sections [5a and 11a at their meeting ends are constructed to accommodate certain conventional parts of the hinges HI by which the latter can be adjusted to fit the floor and jamb parts of the hinge to properly mount the door in the doorway.

Where the door DI is mounted in the manner described the railsV R2 carried by the Vertical and Ho of thetwo door frames are provided with rails R3 and R4, the confronting sides '15 and 46 ofwhich are beveled transversely, and one Vertical edge of the rail R4 is formed with an astragal 41 to span the joint between the rails when the doors are closed.

This as well as the other forms of rails, illustrates the versatility of my door frame construction in its adaptation to single or double doors, and irrespective of the manner in which they are hung.

Although I have herein shown and described only two forms of doors and various forms of jamb rails, each embodying my invention, it is to be understood that various changes and modifioations may be made therein without departing from the spirit of my invention and the Spirit and scope of the appended claims.

I claim:

1. In a door: a panel; and a frame having side and end Sections, eachV of which has in its inner edge a longitudinally extending dove-tail groove, and a right-angled groove paralleling the dovetail groove; a pair of :panel securing strips for each of said Sections, one having a dove-tail tongue engaging within said dove-tail groove and coextensive in length therewith, and the other having a dove-tail tongue removably fitted transversely in said right-angled groove and coextensive in length therewith; and means extending through the last mentioned strip and into the respective section for detachably securing said strip to said section and the tongue in Said groove. i 2.
