Patented May 26, 1942 o reo STATES ADJUSTABLE END sLmE G'itILLE H I, John F. Farmer, Indianapolis Tnd. I I Application August 22, 1940, Serial Nessa-s10 7 Claims.

This invention relates 't'ijgrillesfr use in Windows, doors and'the like which will be neat in appearance and ine'iipen'si'v'e in manufacture and in which it will be adjustable in its width to fit a wide range of door or windcw openings.

The further object is to provide a grille that will have a planar side betweehth frame to pass over stiles or paneling as in doorsmrithout interference, and to provide holes in the frame'of the grille in two directions at right angles to each other for the passage of nails or screws in either direction for the fastening of the grille according to the requirements of the window or door.

I accomplish the above and other objects which will hereinafter appear by the mechanism illustrated in the accompanying drawing, in which Fig. l is a View in side elevation of my grille, with one of its adjustable ends at its innermost limit and with the other end at its outermost limt of adjustment, the top horizontal and adjustable frame member being broken away in part and sectioned to show the inner frame member;

Fig. 2 is a fragment in section on the line 22 of Fig. I looking iri'thedirection of the arrows;

Fig. 3 is a like section on the line 3-3 of Fig. 1; V f

Fig. 4 is a detail in section on the line i l of Fig. 1; and

Fig. 5 is an end elevation of the grille looking in the direction of the arrow 5 in Fig. 1.

Like characters of reference indicate like parts in the several views of the drawing.

The grille filler 6 comprises a series or parallel horizontal rods 1, which are welded, soldered or otherwise fastened to a plurality of vertical rods 8 all laid on the same side of the rod assembly '1. Similar rods 9 (see Fig. 2") are laid at right angles to the rods 8 on the opposite sides of rods 8 from rods I, and are welded, soldered or otherwise fixed to the rods 8, there being one red 9 so secured to rods 8 at each end 'of said 'rods' on top and bottom of the filler 6.

The vertical rod 8 at the ends of the horizontal rods 1 are on the same side as the rods'8. The ends of the rods 1, opposite the mass, are covered by a narrow flat strip of metal 8" looped over the rod ends and soldered to the ends and to ShdWi'lifi Fig; 2', I'ISZV corrugations H extend in'g longitudinally oronejof said flanges on each tube. One of these tubeslfl is s'lip'ped ndwise on the wire rods '9 which enter a corrugation II with the ends of rods 8 iiith split between the flanges of the tubes. The ends of rods 8 may be welded or otherwise fasteh'd'to th'tube if desired but in'practice the withdrawal df the'tube's I0 is prevented by friction. This completes the structure of the filler 6. The tubes H] in practice are formed out of metal strips.

The grille is made adjustable ill width, or herizontal direction, by providing the filler with adjust'able ends [2, l2. As the two ends 12 are alike iii construction and operation, except one is in reverse order to the other, 'a description of one will s'uhice' for both. j'

A series of rods I3, one for each rod 1 bf the filler, is passed across the inner side of its adjacent rod 8 under the loop of strip 8 andacro'ss' the inner side of the'next vertical rod 8, and withdrawal is prevented by the inner ends of the rods l3 being bent in a loop around their adjal5, split along onesiae and having flanges with a corrugation or channel IS in one of the flanges, as described for tub'elll, is slid over wire is and the ends of rods 13 as shown in Fig. 4. To each end .of the tube I5, short tubes I! and [8 are welded, 'andslide over their adjacent tubes lil as shown in Figs. 1, 2 and 3. The tubes H and I8 are substantially of the same length as the rods l3. v

The ends of the tubes l5 are extende past tubes l1 and I8 and have perforations l9 and 20 at right anglesto each; other for the passage of nails or screws used in fastening the grille to window or'dodrfth'e two directions" being alternate ones for use according to the support to which the grille isfastened.

In the operation of my invention, the ends l5 may be drawn out from or pushed in toward the filler 6, limited by the distance of travel permitted by the loops on the rods l3, which is the distance between the adjacent pairs of rods 8 as shown by broken lines in Fig. 1. As best shown m n-1g. 2, the loops and horizontal wires are on one side of the vertical wires 8 leaving the other side planar between the frame to fit closely against a similar supporting surface on door or 55 window. The rods I 3 are locked to the rods '1 by a clamp'zLtlghtened by a screw 22 as shown in Fig. 1.

While} have herein shown and described my invention in the one particular form, it is obvious at each end of the horizontal series and a plurality of intermediate vertical rods between the endrods, all of said rods being rigidly. attached at their intersections, rails secured to the top and bottom edges of the filler, rod extensions for the horizontal rods, each looped at its inner end around an adjacent horizontal rod and slidable thereon between a pair of intermediate vertical rods, a strip looped over the rod extensions and adjacent horizontal rods and fastened at the ends of the loops to the end vertical rods, and a vertical member to which the outer ends of the rod extensions are fastened.
