I sections.

An object of this'invention, is to provide a window sash having mullions and cross mullions joined together to provide a plurality of light spaces each mullion; being formed ofa single strip ofmaterial.

Anotherobject is to provide window sash inullions,',which, when joined together, are

extremely rigid and will not spreadfand leave the glass loose in the frames. 1 1,. p A further ob'ect' is to, simphfythe construction of the' rnullions and the joints at the intersections of same, whereby less tlme will be required in the manufacture thereof, andthe-cost will be substantially. reduced. A further object is to providenovelme'ans for joining together at predetermined spaced intervals, .mullions of any cross sectlonal shape, so long as oppositely disposed r bs are formed on each mullion, one of such ribs being used to provide means for retaining-a pane of glass or the like between themulhons andlcross mullions. y s i I j Other objects and advantagesof our invention will become apparent from the following description. I I

In the drawings we have shown preferred embodiments ofour invention. In'this show- 7 Figure 1 is afront elevation of a window sash provided atthe top thereofiwith hor1-- zontal and vertical mullions, and atthe bottom with angularly disposed rnullions,

the joint as. used. in the'arcuateshaped mule lions shown in Figure 2.

Heretofore, it has been customary Window sash manufacturers to form one mullion of a single strip, a pluralit of the single strips being arranged either vertically or horizontally Within a window I sash. The

cross mullion however, was formed of a plurality of sections joine'ditothe'single strip v mullions at spacedintervalsi' This construction was found to be disadvantageous in that the finished structure was not suificiently rigid,"and= would spread atthejoints whereby the glass would become'loose in the frame.

Of ,course, where there is only one mullion and cross mullion used in a sash, that is, where OIIlYOIlQJOlIlC- 1s to be formedbetween ,--I.u -ri" E(STATES PAT ricsf among 1 the mullions, single strips may be employed, butwhen it isnecessary to form a plurality; I

of joints it was found diiiicult to formcross mullionsof single strips and at the same time provide a tightly fitting joint.

With the present invention the cross iiiul lions may also be formed of a single strip and jolnedwlth the intersecting mullions at predetermined spaced intervals, wthout 'ina'te rially weakening the oints of the iinishe l structure, a frame being provided which is V rigid andiin which panes of glass may be held wlthputty or like material, it having been found that the joints formed Willnot spread, regardless "of the number of'jjoints necessary.

' The construction of the joint hereinafter shown may be used with, mullionsof any cross sectionalshape where oppositely disdesignates a mullion as a. whole which may be placed in either vertical v or horizontal position in ,a window sash. As shown in Figure 3' the mullion is provided with an. upper I rib 11, the sides thereof converging toward 6 is'a sectlonal vlew taken substanthe top, and a lower rib 12 oppositely disis posed from therib 11, without converging sides, the Width of the upper surface of. the

i V Thesides 13 of the mullion extend outwardlyJasshown inFigure 3 and a narrow ledge .14 is formed on the upper face of the side 13, between the edge thereof and the lower edge of the rib. 11. "A relatively wide lower ledge is formed on the lower face of the side be- 7 tween the edge thereof and; the lower rib' l2, 'anda pane ofglass or the like'is. adapted to g N be held in positionagainst the ledge15,*'asw1ll f lo:

be-understood.-u v V .17 a Toform a tightlyfitting jointbetween the V mullionabove described and a crojo mullion of substant ally thesame cross SBCtlOIlitt con- V tour, it is necessary to cut the mulllon 1n the Tao following manner. The 'mullion 10is-cut wardcut has been made, the'side portionsadtially the same width, the width of each peritionl8 b eingequal to the width of the'lower rib 12. *Adjacen't each bevelled portion 17 the-sides 13 are cut away from the llower extremityofthe main cut16 to the top of the l ledgell, substantially as shown at 19', whereby transverse cutaway portions l9 are provided adjacent the bevelled portionsipl7'.

1 Each side'face "13' is thencutinwardlyjas shown at 20 the width'of the cutbeing equal ftoithe width ofthe rib.12,.andalowercentra1 1 portion 21 is left betweenand of the same width as the centr'al portions '18; a

It will be seenthat the cutn'cessary to be made in the cross Inullion will be different from that ust described. The cross. mullion .40 l vided with u per'and'loWer ribs 23 and 24: respectively, and sides 25. The upper rib 2 3 converges upwardly'and a small ledgei26 1s 22,;shown in Figure 3 is of substantially the same contour as the mullion 10, 'bein'g pro formedcorresponding'tothe'ledge 14. A

relatively wide ledge 26"isalso' f formed corresponding to the ledge 15.; The cross mul-l I jlion 22 is cutsubstantiallyhalf way through froinithe bottom of the rib 2.4 as shown at J "27, the width of the cutbeing eq u'al'tothe' 23 are bevelled as shown at 28,"the central I portion 29 between said'portions 28 beingleft substantially the same width as the opening 27. From the outerextremity 30" of the width ofthe rib 12. Aboveithe opening-'27 theconverging side faces of the-upper rib bevelled portion 28 the sides 25 are cut parallel to the sidesiof, the opening 27. Thesi'des 25 are then cut .transverselyas shown at 31,

i so

' ftions' 323 are providedof a width equal toithe the cut extending inwardly to the .s'ide face of the rib 24 as shown at 32. Central por width of the rib,24,

It will be obvious that the mullions and cross inullionsmay be out at predetermined intervals and when it'is desired: to join them together, the mullion'22 is placed withits cut out portion fitted into the cut out portion 16 of themullion 10 and when properly fitted togetherthe bevelledfaces 28 of the mullion 22 engage the bevelledfaces 17 of-the mar tions 19; and the central; portioni21 -=willenwhereby a neat and tightly fitting joint will result. I a

In the construction shown in Figure 7-the cuts are made "similarlyto those above described except thatthe cuts will be madelatli the'desiredangle, aswill be apparent.

The above described construction provides I Inullions'and eross -mullions both of which may be formed of a single strip .oflniaterial intervals. The glass isadapted to be secured putty in the'usual manner,the frame will be rigid and will not spread 'whereby theg la'ss will become loose. After thernullions-have.

beenjoi'ned together as shown in Figures'l and 2, the-outer'frame "or stile' may' be se} I T cured in position.
