ApplicationIiIedfIVIaTCh'IS, 1921.

duce a marketable sash of great* stiffness` and durability which can be easily and economically manufactured. In its preferred form my invention contemplates` a sash composed of metal parts, preferably rolled shapes such as may be easily producedyin arolling mill. The various features and advantages of my invention will be best understood.` upon referencey to the following detailed description taken in connection with the accompanying drawing, andthe scope of the invention will be particularly pointed out in the appended claims. n

Fig. 1 is an elevation of a sash constructed in accordance with the present invention, the same being yviewed from the outside; Fig. 2 is a similar view of the same sash viewed from `the inside; Fig. 3 is an enlarged elevation of one ofthe joints between the bars of the sash, viewed from the inside; Fig. 4 is a sectional view of the same taken on a plane indicated by the line 4-4 of Fig. 3; Fig. 5 is a view similar to Fig. 3, the parts being viewed from the outside; Fig. 6 is a sectional view of the same taken on a plane indicated by the line G- 6 of Flg. 5; and Fig. 7 is a sectional View similar to Fig. 4 illustrating the` parts with a Joint 1n the glass directly behind one of the bars. Throughout these views like characters refer to-like parts.

Referring to the drawing in detail, the frame of the sash is-made up of stiles 10 and rails 11 which are secured together at their corners in any preferred way. In the preferred formof the invention these stiles and rails are composed of metal andare welded at the corners. Bars12and 13 ex'- tend between the stiles and rails, respectively, to complete the sash structure;` The bars 12 constitute one*` set, and divide-1l the space within the sash frame into longpanz# els-or spaces. extending from. one s1de` o f the vsash tothe other. The bars:.13\.c.onst1. tute: a second set and` divide theV whole space in the same way butzthevlong panelsrlie'at right anglesrtothose provided bybarsf12, due to the factthat'thebarsf12` andy 13` ex`` tendcross-wise of `each other.V Tlieseveral Serial No. 453,685.

bars arefsecured to the stiles and rails in any preferred'way` and their number `may be varied to furnish the subdivision of the whole space, which has been decided'upon.

'Iliebars' 12 and 13 may also bevaricusly shaped. A slight modification of many different forms of angle-bars will suffice to produce bars whichr will perform the re-` quired functions. Thus'in forming mybars, Imay use as basis, H-bars, I-bars, ,L-bars, T-bars, Z-bars, channel bars, etc. In view of this fact it will be understood thatfthe 'EI-bars herein disclosed are therefore merely illustrative.`

As clearly-shown, each of the bars 12 and 13` is composed of' two constituentmembers, onecalled` theflange andthe other the web. In the finished structure,uthe iianges ofthe bars 12 are secured'tothe flanges of the bars 13 and the webs extend outwardly. Since in other forms of angle-bars, the webs may be secured together and they fianges extend outward, Ihave chosen to call those members which are secured together main members and those members which extend outward auxiliary members.

Inthe form of the invention chosen for illustration, each bar 13 is provided with two sets of longitudinally aligned ribs 14 whichl extend from that face ofthe main member which is farthest from the auxiliary member. These ribs 14 extend only between the bars12. In other words, if the bar 13 is rolled so as to provide continuousribs 14, then those ribs are cutaway at the points where the bars 13 cross the bars12. The ribs 14y are of equal height and may closely approach the glass 15 as shown inFigs. 4 and 6, or they may bear permanently against the glassasshown in Fig. 7. In either case the ribs bear against and support the glass when iitlis subjected to heavy wind pressure whichwill ofcourse be exerted mainly from the outside. In the formercase the support-l ing actionfdoesfnot take place until the `glass is deflectedl fary enough-V toengage the ribs.A In the latter case it. takes-:place without waiting `for the glass -to-f be-ldeflected; The latter is fthe preferableconstructionfor it` is desirable: tovsupport the glass asf-much as possible;y

Thevba'rs .125 which asfbefore,findicatedmre also: shown as.;T-barsy;.haverV sma1lribs 16 Vvon opposite sides of their auxiliary members. The space between each rib 16 and the adjacent face of the main member constitutes a groove or receiving space for the edge of the glass and the put-ty or other retaining material 17.

The main members of the bars 12'vand 13 bear directly against each other in the iinished structure and they may be secured together in any suitable way. In the preferred construction these bars are preferably welded together. Of course other means for securing them maybe employed if desired. As previously noted, the auxiliary members of the bars 12 extend outwardly and form ledges for the support of the glass 15. The latter is preferably provided in the form of strips which extend from stile to stile and occupy the spaces between the ledges. These strips of glass 15 are made of such a width that they may be easily passed over the ribs 16 into their final positions in the grooves formed between the ribs and the adjacent faces of the bars 12. In this position the glass may be brought to bear directly against the adjacent faces of the bars 12 and the outer surfaces of the ribs 14 on the bars 13; or, they may be brought into close proximity to these parts, as previously noted. The glass 1s held in place by putty or other retaining material 17 as before noted.

In case it is desired te use short lengths of glass instead of strips running from stile to stile, the same may be jointed so as to bring the joints in line with the bars 13, as clearly illustrated in Fig. 7. In such event the joint should be brought at some point between the ribs 14 so as to enable the putty or other like material 13 which lies between the ribs and against the glass, to properly close the joint. In the case illustrated, the joint lies directly behind the center of the bar 13. Obviously this is not necessary, although giving the parts a better appearance from the outside. It will be noted that in this instance the ribs 14 bear directly against the glass. Obviously, a satisfactory joint could be made even though the fit was loose at this point, as in Figs. and G.

From this description it will be seen that I have produced a sash which has great stiffness against wind pressure because so little of the bars is cut away, and at the same time I have produced. a structure which can be cheaply and readily manufactured. The latter advantage is contributed to by the fact that so little cutting needs to be done upon the bars.

It will be apparent that in carrying out my invention, many alterations and modifications may be made in the specific structure disclosed without departing from the spirit and scope of my invention. Thus, the bars of the sash may be variously shaped as I have heretofore pointed out. These and other changes will readily suggest themselves to persons skilled in this art. I therefore do not wish to be limited to the specific structure herein disclosed but aim to cover all such alterations and modifications by the terms of the appended claims.

Vihat I claim as new and desire to secure by Letters Patent of the United States, is:

1. A unitary metal angle-bar comprising main and auxiliary longitudinally continuous constituent members, said members in right section meeting at an angle, said main member having a plane face on its side farthest from the auxiliary member and'ribs of equal height extending from said face in two parallel longitudinal rows located near the outer limits of said face, the ribs in each row being spaced apart and each rib being opposite a companion rib in the other row, said companion ribs forming with said face aligned channels along the angle-bar, and all right sections of the angle-bar exclusive of said ribs being identical in area and outline.

2. A unitary metal angle-bar comprising main and auxiliary longitudinally continuous constituent members, the auxiliary member joining along one edge with the main member at an intermediate point in the latters width, said members in right section thus meeting at an angle, said main member having portions of its surface on its side farthest from the auxiliary member lying on a plane and having parallel longitudinal ribs forming with said plane portions channels along said angle-bar, all right sections of the angle-bar including said ribs being identical in area and outline.

3. In a sash, two sets of angle-bars, each angle-bar comprising a main member and an auxiliary member, said members meeting each other at an angle, the sets of anglebars crossing each other and the main members of both sets engaging each other and being secured together at crossing points, the auxiliary members of one set of angle-bars forming supporting ledges for the glass, and the -main members of the other set having ribs projecting toward the glass between the angle-bars of the first set,

e. In a sash, two sets of angle-bars, each angle-bar comprising a main member and an i auxiliary member, said members meeting each other at an angle, the sets of angle-bars crossing each other and the main members of both sets engaging each other and being secured together at crossing points, the auxiliary members of the one set of angle-bars forming supporting ledges for the glass, said auxiliary members having glass-retaining grooves on both sides of each member, and the main members of the other set of anglebars having a plurality of rows of ribs of equal height extending toward the glass between the angle-bars of the first set.

5. In a sash, glass-supporting bars, glass positioned on said bars in a plane intersecting said bars, other bars secured to said first mentioned bars at engaging points and lying Wholly on one side of said plane, said other` bars having each a main portion spaced from said plane and projecting ribs extending to- Ward said plane, said ribs forming on eaoh said bar a channel neXt to the glass, and retaining material in said channels.

6. In a sash, sets of crossed parallel bars, glass positioned between bars of one set and having a joint opposite one of the bars of the other set, projecting ribs extending from said latter bar toward the glass on opposite sides of said joint, said ribs and bar forming a channel along the joint, and retaining ina terial in said channel.

In testimony whereof, I hereunto suhscribe my name this 17th day of March, 1921.

WILLIAM C. CORYELL.
