My invention relates to improvements in window construction and the main object is to provide aneilicien't, durable, and non-rattling meta! window sash and frame having ,5 also a number of other features as hereinafter fully set forth, reference being had to the accompanying drawings, in which,'--l

Fig. 1 is an inside elevation of m improved window, in a four-pane type an hinged at one side a .so-called easement window.

Fig. is a horizontalV cross sectional view about as o1. line 2-2 in Fig. 1.

Fig. 3 is an enlarged sectional perspective a single glaze type of sash and window channel of my improved type and includin a certain metal clip for retaining the edge or the glass.-

Fig. t is an elevation of preferred window pane retaining bars for a tour-pane type of 4window as illustrated in Fig. 1.

. Fig. 5 is a perspective, 'enlarged detail oi a channel type `.muntin bar used with the retainin bars shown in Figs. 2 and 4.

Fig. 61s a cross sectional detail of the u per bar of my window sash, in a modified orm adapted to be hinged at the lower frame bar and including a manually released' spring operated latch device.

Fig. 7 is a cross section of an I-beam shaped muntin bar 'for double-glaze windows and Fig. 8 is a cross section of a preferred type of hollow muntin bar used in single glaze windows of my improved type.

355 tion of the muntin bar shown in Fig. 8, look- --are in quadran Fig. 9 is a front oi' face view of an end pors ective view or a corner of one of the winow-sash shown in Fig. 11.

Fig. 12 is an elevation of the quadranguf larly arran ed pane retaining frame members as use inthe types of windows shown a0 in Figs. 10, 11 and 13.

.Referring to the drawings by reference numerals it will lirst be understood that l aim to provide an all-metal window frame, usually of course uadrangular and embodya ing suitably joine lates 15'to the vertical ones of which may lib fixed elongated metalv sash-weight pockets 16. 17 in Fig. 1 illus- .trates face boards or plates of suitable size t and extending. from main frame 15.

18 are metal channel members suitably fixed by welding, or otherwise, to the vertical frame members 16, in pairs as in Fig. 10 for two-sash windows or in single continuous @5 quadrangular formation as in Fiss. 1 and 2 for hinged sash. In all types of windows embodying my improvements these channels have an outer wide flange 18A and an inner narrow, ange 18B. lin the sliding sash type 70 of windows these channels are the runways for the sash and in the easement type they lar formation and the sash swung into position within the uadran lar channel frame as will presently e described. The swin 'ng type wil be first described.

n comination with the stationary means just described my improved window com-- prises further, a metal sash, single or double, and a certain type oi storm sash, the latter a0 embodying certain pane retaining features common to all types of sash herein described.

ln Fi 1 l have illustrated a horizontally swingab e four pane singleV sash A hinged at 184: to the main frame 15. lin this sash iframe a5 and the modification thereof in other views4 the general designation A will be used and variations in details designated likewise with numerical suiiixes, for a more ready understanding of its construction. w

e outer edges of the @u 4 shoulder A4 in vertical of the inner part or' this ledge is formed a The sash A is of course quadrangular being formed of 4 quadrangularl arranged suitabl joined (as by welding sash bars, each of ormation, in cross section, comprising an ,outwardly directediange A1, anA inwardly adjacent continuous groove A2, in the inner part of the latter is a continuous ledge A3 and continuing inwardly from'this ledge a continuous central, hollow ridge or rib A5 (see Fig. 3) from which the metal is shaped to extend inwardly in certain, modified ways and terminates in an inner outwardly directed ange A6 in vertical plane, said latter flange adapted to bear against the inner ange of flange 18B of the iixed channel `'rame 18 simultaneously as the sash flange the ed e of channel ig. 3) w en the swinging sash (of Fig. 1) is closed, said flange A1 overlapping as shown best in Fig. 3.

19 are fixed, crossed muntin bars in the A1 engages lightl ilange 18A (as in i sash,for a four pane sash frame (see Fig. 1)

bars are kept apart each with its ends suitably fixed in opposite ridges A5 of a sash. Thesevbars are illustrated as shallow channel irons, in Fig. 2 and Fig. 5 the opening of the channel being toward the glass and to receive putty or other glazing flush or little outwardly of the channel for the glass 20 to bear against. The adjacent edges of the panes at said muntin by fixed parting lugs 21 in said channels each having a projection 21P to register with openings 22? of crossed pane retainin metal bars 22 bearing toward the face of t e glass by having their ends slidably inserted and` sprung into grooves A2 of the meh rs A (see Figs. l, 2, 4 and 5) ln a single pane type of sash (as in Fig. 2) the glass 20 is cut in a size permitting 1t to be passed inwardly between anges A1 of the sash bars and against shoulder All after which putty as 23 is filled in the groove A2 to retain the glass. .2A is a dat spring metal clip formed with a ledge 24A adapted to rest on shoulder A3 thence curved up in a Asemi-circular hump and extended down thence to engagein the front, lower part of groove A2.` The humped part is frictionaly engaged by the edge of the glass (see Fig.

3) and it will be .understood that each vclip is retained slightly compressed in the groeve and ledge parts as shown, the clips being in serted in predetermined spaced relation before puttyor the .like is applied, the clips being of course entirely if... nidad.

In Fig. 6 is shown, in cross section, an`

upper bar' of a sash hid at its lower edge, such as a transom sash. rlhis is a double glaze sash with modified bar section and includes a spring metal latch `bar`25 xed at 26 on the inner part of ledge A3 extending upward angular-1y (normally) thence plane and inwardly sash from their grooves,

Lacasse down, at 25S, angularly and outwardly through an aperture 27 in the bar, outwardly of which it is' formed with a loop 25L or other suitable engaging means. The part 25S normally is pressed upward against and pinches the flange 18B of channel 18 thus holding the sash sash is released by simply pulling down loog 25L so the spring `can pass under flange 18 and permit the sash to be swung open asin direction of arrow 28. In thisv double glazed sash the groove A2 is narrow and deep and ledge A3 comparatively wide. rEhe muntin bar is an I-beam in cross section (see also Fig. 7) and inwardly of the rid e A5 an inner edge A3 is formed for t e inner pane 20.

In this case groove A2 forms a continuous quadrangular pocket for retaining respectively an upper iiat metal retaining bar 29, opposite vertical' bars, 29B and a bottoni bar 29C, (see also Fig. 12) all of a width to project inwardly toward the center of the and between which projecting parts and the pane, puttyis inserted (best shown in Fig. 6) For retaining the inner pane, vlike bars 29, 29B and 29C are used but may be secured as with screws 30 to 'the sash bar.

19B in Figs. 8 and 9 illustrates a hollow, rolled metal muntin bar, as an alternative for 19, and for single pane sash only,`said bar being approximately triangular in cross section and having a vertical face for adjacent pane sections to bear against. In said vertical face is a lon 'tudinal slit 31 widened at .its ends at 31A or insertion of a nut'32 and screw 33 provided in suitable numbers and adapted to engage in apertures 'of a glass retainin bar 22B which thus covers the adj acent e ges of the anes and may be clamped against the glass y said screws.

In the forms of window sash above described I have disclosed'single sash construction only, I will now describe double sliding sash as in ordinary house construction, where there is an u per and a lower sash slidable in parallel p anes, this being done inl my improved window device-by providing in each frame 2 fixed channels 18 on opposite vertical members 16 of the main frame. The adjoining bars of the two sash must of course come to parallel, horizontally registering ositions when the window is closed, as in ig. l1, where double glazed sash are shown but single glazed equally adaptable.

' n these horizontal bars I provide a hollow bar construction for weather proof construction',embodlying the barA as described but to each of w ich is fixed asat v34 a horizontal channel corresponding 4to the ixed 4channels 18 of the mam iframe. -lhe upper rigid when closed. Thel memb their front and rear anges are cut away at the ends and the webs continued to fit slidably and transversely in the main frame channels 18, as at 36 in Fig. 13. 37 is a metal plate secured on either or both bars 35, as on the right hand bar inFig. 11, said plate overlapping a portion of the adjacent sash cross bar to provide a weather proof joint at W. 38 are apertures in the guided end web parts of the bar through each of which a sash cord 39 extends upwardly from any suitable cord attaching means such as the fixed eye-bolts 40 (Fig. 10) in the vertical sash ers A.

It will now be readily understood that my invention embodies a metal main frame with integral elongated inwardly opening channel members between which is the space occupied by either sliding or swinging sash, the latter kind involving, selectively, sash hinged at either side, top or bottom. Further, means are provided in the making of the sash bars for either single or double glass and in Fig. 2 is illustrated a storm sash mounted within the main frame, whether fixed or hinged.

In said storm sash, Fig. 2, the glass 2O is retained in sash bars 41 of approximately but distorted S-shape in cross section having an outer, inwardly opening glass receiving groove 41G corresponding to groove A2 (Fig. 3). Inwardly of the glass retaining groove the frame is formed as a continuous vertical. flange 1F movable inwardly to stop position against the outer flange 18A of the main frame channel. rIhe thickness of sash bars of said storm sash is such that it may be inserted slidably within and between the parallel channels 18 to serve as a sliding sash therein.

In Fig. 2 I have also illustrated, on the left upright sash member a cam 42 on a pin 43 having a hand operated lever 44 accessible inwardly of the window to swing the cam into engaging position inside of the channel flange 18B and thus hold a easement window closed positively.

Ll5 in Fig. 10 are upright interior bars in fixed parallel relation to each upright fiange A6 of a sash to provide vertical guide means for the slidable sash.

I claim In combination, a window sash comprising a quadrangular frame of joined metal bars,

ridge formed in each bar inwardly of said groove, muntin bars fixed with their opposite ends in said ridged parts of the sash bars and means for holding panes of glass in the sash with .their adjacent ed es at the muntin bars in spaced relation an removable auxiliary muntin bars arranged to lie over said adjacent edges of the panes, the outer ends of said auxiliary bars adapted to be removably engaged in the grooved parts of the sash bars.

In testimony whereof I aix my signature.

OTTO A. MUNSON.
