Application september so, 194e. serai Ne. asalto s claim. (ci. iss-1e) My invention relates to a metal sash and metal frame construction for use in windows. doors and the like whether having glass in the sashor opaque panels. The sash is of a type that may be employed either sliding such as double hung sash for a window or as hinged easement sash.

In many types of metal sash for windows or for folding opaque panels, the design does not permit the glass or panel to'be held in place by glaziers points or glaziers nails prior to retaining the glass in place by putty and further most of the metal sash for engaging glass or panels requires bending operation by the person iitting the glass or panels in the metal sash. In'other types of construction the edge of the glass or lpanel nts quite snug into a channel shaped to engage the edge and two sides of the glass in which case the channel must be substantially the correct size and some type of padding utilized in contact with the glass. i

Inother typesthemetalof thesashisinthe form of quite a wide channel with the edges of the sides curled inwardly and forming a resilient contact with the glass but these structures unless the channel is illled with some suitable material do not adequately retain the glass in place and some of them in fact require a wood filler, the metal of the sash being in effect a covering for such filler.

A main object and feature of -my invention'as it relates to the construction of the sash proper is in providing anedge support or centering construction for the sheet of glass or panel to engage the edges of such sheet or panel having a resilient .t

iiange-like member contacting the glass or panel on one side on a line spaced from the base. On `the opposite side I also have a second flange shorter than the ilrst and preferably curled outwardly ,at its edge, this also being adapted to engage the glass near the base. Both flanges however are yieldable and the second flange due to the curl provides a guide for driving a glaziers point or glaziers nails which cause a wedging outwardly of the second flange, then putty may be illled against the glass at such second flange embedding the glaziers points and thus producing a finished sash made in a simple manner. As a further detail feature of my invention the sash as to .the bottom and top rails and the two stiles and main construction of the meeting bar if such is used are constructed from sheet material made with an outwardly facing channel with the web inwardly and two outwardly extending sides and formed integral with each side is the first and secbend. this giving the resilient construction to the l through a perforation of the webs engages the outer tace of the panels or glass and this may be coverm in with putty. My invention also comprehends such details as a meeting rail for sliding sash formed by an outside resilient strip engaging the lower rail oi the upper sash. Qther features include a cover for the top rail formed of metal and being used as a device ior vertically sliding the sash. Otherfeatures include forming a irame of sheet metal bent in channel form with a reverse bend as to one iiange so that these may be built up forming guideways for sliding sash. With this construction one of the guideways may be crimped around the outside of bars of the rails or stiies ofthe sash and thus Abe used in easement sash where it is necessary to have sumcient stiiening.

My invention is illustrated in connection with the accompanying drawings, in which:

Fig. 1 is an elevation oi a window illustrating my invention applied thereto taken the direction oi the arrow i of Fig. 2.

Fig. 2 is a vertical section through the window ontheline-t of Fig. l.

Fig. S is a horizontal section on the line 8--3 of Fig. 2 showing one ci the stiles and the side guides for the window, the top and bottom rails oi the sash being of a similar construction.

Fig. .d is a detail section through a sash bar on thc line -li oi Fig. l inthe direction of .the

arrows.

Fig. 5 is an elevation of easement sashas taken fromthe inside in the direction oi' the arrow 5 of Fig. 6 is a horizontal section on the line 6-6 of Fig. 5 in the direction of the arrows.

Fig. 'I is a section through one of the stiles and may be considered an enlargement of one of the stiles as shown in Fig. 6.

Referring iirst to the sash construction desigso natedv bythe assembly numeral il, this is made up oi.' top and bottom rails and two stiles, each formed substantially as follows being provided with an outwardly :facing channel I2 having'a web I3 and two sides identified as Il and I5.

ond flange being connected thereto by a reverse From. the side I4 there extends a long flange I6 connected by a sweeping reverse bend Il. This has the inneredge I8 spaced a considerable distance from the base I3. A second ange I9 ex tends from the side I5, there being a sweeping curve 20 similar to the curve Il. This ilange has an outward flare or curl 2l terminating at an edge 22, this edge being but slightly spaced inwardly of the sash from the web I3. This second flange is thus considerably shorter than the rst flange.

In fitting a pane of glass such as 245, note Fig. 3, the glazler proceeds much in the ordinary or conventional manner. The web I3 and the ange iS :may be considered as forming a rabbet over which is smoothed a coating of putty indicated by the body 26. This thus forms a thin film of putty along the .web I3 completely around the opening of the sash. The outward curl 2| of the flange I9 and its edge 22 are so proportioned that they allow the glass pane to be fitted through the opening formed by the outline of the edges 22 and bed the glass on the putty smoothed into the rabbet. A series of glaziers points 2l are then driven between the ilange I9 and the base It of the outwardly facing channel. These .points or glaziers nails press against the outer face of the glass pane and cause a wedgingaction which forces both flanges slightly outwardly from contact with the web, that is, the glass pane is forced inwardly sufcient to bend the web I from the dotted to the full line position of Fig. 3 and the ,driving in oi'f the points wedge the outer flange IS from the dotted to the full line position of the same ligure. The glass pane is thus firmly held in position for the glazier to nish 'puttying at his convenience. The outer nish of putty 2B is lined up fwith the edge 22 of the curl ES and some of this putty is forced into the space between the side I5 of the channel Ii and the flange is, thus the pane of glass is adequately bedded in putty but the edge I8 o'f the flange I e has a contact with the inside of the glass pane. As the mlter joints are made in the conventional manner, these are not illustrated in detail, the sheet metal lbeing soldered or brazed at the joints, or other suitable construction.

Where it is necessary to have sash bars, these are constructed as shown in. 4 in which the sash bar 35 is formed of a strip of sheet metal bent to have two parallel webs 36 with a reverse bend 3l causing such webs to be but slightly spaced. Each web has a flange 38 forming an acute angle 39 with the web. The two webs have aligned circular perforations or slots d. This is to accommodate a resilient locking -pin la which has a central bent section Ml and two opposite end portions d5 which bear on the opposite sides of the glass panes. In this constructionthe anges 38 engage the inside face of the two panes oi glass, the locking pins or keys d3 retaining the glass on the outside and then a bedding of putty 46 forms the finish.- This trims off with the putty coat 28. These sash bars are mitered and soldered to the stiles and the rails of the sash in a conventional manner.

Where I desire to use the sash for window closure of the sliding sash type, I construct this as shown in connection with Figs. 1, 2 and 3. A convenient manner to retain the sash in adjusted positions when open or to hold up the upper sash is by the use of leaf springs 5U, note Figs. l and 2,

in. which one end is secured to the web I3 fitting in the channel l2. The hump is bowed outwardly and the other end slides on the web. These springs engage retaining devices on the sides of the window frame or thespace of the Vchannels 2 agencer The window frame assembly 55 employs guide i channels 56 for the stiles, these having a web 5l, a single flange 58, a double llange 59 having a reverse bend G0 and an outer locking flange BI. These channels are assembled as shown in Fig. 3, the harige 58 of one channel fitting inside of the locking flange I. At the sill 65, a single angle is used :for an inner flange S6 and a sill flange Sl. At the lintel or top of the window there is a lintel ilange 'l having a water drip downwardly extending ilange II and a horizontal flange l2 secured to the lintel of the window frame. By this construction it will beseen that the sliding sash may be iitted in the guides formed -by the channels 56 and thus slide vertically. One or both of these may be readily removable in case it is desired to take the sash completely out of the window. Y

vFor double hung or sliding sash I employ a meeting rail assembly l5. This includes a sheet metal strip, note Fig. 2, having a horizontal header 'le and a resilient outside strip l?, there being a curled ringer grip edge l@ on the inside. A cap for the upper sash 8@ has a similar bend I6 and linger grip i8 but has the downwardly curled' edge BI soldered or brazed. to the outer short flange I9. When the sash are in the closed .position as shown in Fig. 2, the resilient strip Il rides slightly upwardly over the reverse bend il on to the lower portion of the flange iS on the bottom rail of the upper sash, thus giving an air tight joint connection and having a sumcient resiliency restraining any rattle of the sash often caused by wind.

For double hung sash I have a simple sash lock 35. This includes a hinge 8b fwith a xed leaf @l attached to the upper sash on one of the stiles and has a moving leaf 88 which may be swung over the cap l5. Instead ory using the outwardly l facing part of the channel I2 in the stiles to bottom rail thus employing the channel structure.

I2 with the flanges I6 and is as shown in Fig. 7. In this case however in order to stien the construction and provide a definite binding on the edge and closure for the frame of the sash, I use channels substantially the same as used for the guides of the window frame assembly 55. In fact, one -of these channels properly bent provides an enclosing channel I00 with a web II, a single flange H32 on one side, this preferably lapping the flange i6 and a double flange |03 overlapping the flange I9. These inwardly bent ilanges of the covering channel are attached to the frame member by solder or brazing indicated at IM. This makes a rigid structure and encloses the outwardly facing channelsxl2 at both of the stiles and the top and bottom rail. The sash bars may be of the same construction as shown in Fig. 4 and built in the easement sash in the same way.

A suitable frame or easement sash for attachment to the window frame indicated at II is formed of sheet metal' having a flat base III for attaching to the-Stiles of the window frame to the sill and to the lintel if desired. This has a illustration shows asash for opernrg outwardly l asit is' the usual practice to have the putty on the outside oi the window where it is subject to the weather. if the sash is to swing inwardly on its hinge, of course the frame itil would be reversed and the hinge secured to the harige it@ of the enclosing channel dei?.

It is believed obvious that the metal sash as above described and illustrated is suitable for mounting panels as well as glass and by proper proportions as to the size of the outwardly facing channels I2, may be constructl for dierent thicknesses of glass, quite a variation in the thiclrness of panels and everior quite thick sheet metal panels, the principle of construction being substantially the same. En fact, where desired, putty may be entirely omitted andinstead of using a series of glaziers points or glaziers nails, a. strip of metal may be driven between the curled flange I9 and the base i3 `of theupwardly facing cha-n nel I2. This strip would then be as indicated by 21 in Fig. 3 as to cross section.

A characteristic or the side members of the sash is that the outwardly facing channels should have a rounded web or base. These may thus be considered as U shaped channels, It is not necessary however that the base be a semi-circle. The outer edge 22 of the flange i@ extends slightly inwardly. of the line of the inner portion of the base. This curl orare 2i should be quite sharp. This construction therefore providesva space and a curved surface on the base for starting a glaziers point. These are usually pressed outwardly as to theglass pane and parallel aloner the side of the pane. The leading end of'the glaziers point or lnail is then deected outwardly by the joining corner of the base" i3 and the ange "i and follows along the insidefof the resilient flange i9. When va pane of glass is thus held in place by the glaziers points or nails,
