Dvidedantl this application October 13, 1948, Serial No. 54,311.' 'In Canada June s This invention relates to improvements in metal windows and is a division ofthe subject matter set forth in my co-pending application Serial No. 763,558, led July v25, 1947, Paten Number 2,570,523, issued October` 9, 1951. More particularly the present'inve'ntion relate s to an improved sectional metal window sash assembly adapted to be used in the window nstallation described in said application and various other types of window installations. p
The object of the present inventionv is to provide an improved form of metal window sash in which weatherstripping elements are arranged in anovel manner between complementary sections of the component rails of the sash so that thermal transmission from the inside to the outside of the metalsash is lsubsequently reduced. Other objects, advantages and characteristics, features of the invention will be more readily understood from the following detailed description of the preferred embodiment of the invention shown in the accompanying drawings, in which- Figure 1 is a vertical sectional view of a metal window sash embodying the invention, and
l Figure 2 is a fragmentary horizontal sectional View through one of the side vportions ofl the sash frame shown in Figure 1. j
As shown more particularly in Figure 1, the bottom rail 5 of my improved window sash assembly is made in two parts comprising a main section 6 and a facing section 1 secured to the indoor side of the main section. The main bottom rail section 6 comprises a web 8 provided with upwardly projecting marginal legs 9 and I and downwardly projecting marginal legs Ii and I2. The legs 9 and Il at the indoor side of main rail section 3 are fitted in a dove-tailed groove I3 in facing section 1. The upper edge of facing section 1 is formed with oppositely directed horizontal flanges I5 and I6. The flange I5 overlies a glazing channel I1 formed by the web 8 and upwardly projecting legs 9 and I@ of rail section 6. The remaining flange I6 of facing section 1 provides a hand grip for raising and lowering the sash. The lower portion of facing section 1 is formed with a weatherstrip receiving groove I9 opposing a similar groove 20 in a leg member 2| extending downwardly from an intermediate portion of the web 8 of the main bottom rail section 6. The grooves I9 and 20 are adapted to receive weatherstripping elements of the type disclosed in my co-pending application Serial No. 763,558, of which the present application is a division.
2 claims.` (c1. 18a-6i The downwardly directed legs II and 2| of railsection 6 form, with the lower portion of facing section-1, a, downwardly opening pocket 23* adapted to receivetherein an upwardly projecting leg of the sill portion of the window frame in which the sash is mounted. Heat insulating material indicated at 2d is interposed between the bottom of the groove I3 of facing section 1 and the opposingv surfaces of the legs 9 and Il of the main rail section 6 so that the only'direct metal-to-metal conta-ct between the facing section 1 and the said legs 9 and II of main section- 6 is along the relatively narrow horizontaledges -of said legs. -t this point it may be noted that the forego ing description of the bottom rail construction of the window sash applies only tothe case where the sash'4 is used as the bottom sash, as disclosed in my (3o-pending application Serial No. 763,558. If "the sash is to be employed as the upper sash of the window installation, the bottom rail member may be constructed in thev same manner as the bottom rail of the upper sash disclosed in said co-pending application. 'Each 'side rail of my improved sash, as shown in the present drawings, comprises a facing section 2'1 which is secured to the indoor side of a main'side rail section 2S by screws (not shown) or any other suitable fastening means. 'I he main side rail section 28 comprises a web 29 having an inwardly directed flange 30 at the outdoor edge thereof. Web 29 is provided with additional flanges 3I and 32 defining a weatherstrip receiving groove 33 opening towards the adjacent jamb side of the window frame in which the sash is mounted and a second groove 34 opening towards the indoor side of the window. Groove 33 is adapted to receive therein a weatherstrip holder of the type described in my aforesaid copending application Serial No. 763,558. The facing section 21 of each side rail of the sash is provided with a tongue 35 extending into the groove 34 of main side rail section 28. A U- shaped metal weatherstrip holder 36 is fitted on tongue 35 and carries a weatherstrip 31. Weatherstrip 31 is folded over holder 3S and has its side edges turned outwardly to provide flaps 3B which are interposed between the main side rail section 28 and the associated facing section 21 to prevent metal-to-metal contact between said sections. Intermediate portions of weatherstrip 31 are folded around and secured to cords 39 to provide substantially cylindrical anchoring portions which are held in cylindrically curved portions 40 of holder 3B. The last mentioned curved portions 40 of holder 36 are accommodated in grooves 4| provided in facing sections 2T at the base of tongue 35. Ridges 43 projecting inwardly from the side walls of groove 34 engage weatherstrip 31 to give an eihcient weatherstripping effect. A portion 21a of the side rail facing section 21iis opposed to the flange: 30 of main side rail section 28 to provide a side .rail continuation of the glazing channel formed by the anges 9 and l0 of the bottom sash rail 5,'
The side walls of groove 33, Figure 2 are also provided with inwardly projecting ridges 44 adapted to engage in guideways provided in opg posite sides of the weathersiripknpmei; inserited in said groove. l
The top rail of the sash frame comprises' a-fac-j` ing section 41 and a main section 48 which 'are substantial duplicates of the facing and main sections of the side rails. Facing section-41 is provided with a tongue 49 extending into groove 50 ofmain section 48 and equippedfwitha weatherstrip holder 5l andaweatherstrip, 52 -corre-, sponding to the previously mentionedholder and weatherstrip 31. `A flange 54 extendsdownr wardly from the outdoor edge of the web 55o! the main top rail section 48 and is opposed to a portion 41a of facing section `4l tov complete a glazing channel in which a glazinsurlit 56, preferably ofthe multi-pane type, is secured by a suitable caulking compound 51.- u w in When the sash described herein is the lower sash of a window installation as shown in-rny cgpending application Serial No. 763,558, the main section 28 of the top rail is formed witha downg wardly` opening recess 59, the side walls of which are formed with grooves 60. The-grooves $0 are adapted to receive therein weatherstrip holders carrying Weatherstripping 'elements which',H s disclosed in my co-pending application, are adapted for engagement with a weatherstrip` ping iiange extending upwardly from the lower rail of the associated upper sash. The main rail sections of the top, bottom and side rails of the sash described herein are'p'referfably formed separately and secured together' in any suitable manner at the corner portions ofthe sash frame. 'l
In the present instance, the mainrail sections of the sash are' shown secured togetherbycore ner members 59 fitted in groovesGD'in' which they' are suitably secured to serve as rail Qconnecting members.
Having thus described the nature of my invention and a preferred embodiment thereof, it will b e understood that various modifications may be resorted to within the scope and spirit ofthe appended claims.
I claim: 11: AA sectional metal sashframe including a main f'section comprising top, bottom and side rails each presenting a web and an outdoor flange extending inwardly from the outdoor side of the web.A said webs and iianges forming, respectively, the'bottom wall and the outdoor side wall of a-fglazing vchannel, vertically aligned indoor flanges projecting upwardly and downwardly from,- the indoor side of the web of the bottom rail and-*having their free longitudinal edges bevelled jso' that they converge in the direction of the outdoor sides of said flanges, a facing plate provided with a dovetail groove in which the indoor iianges of the bottom rail are fitted and additional facing plates removably secured to the bottom sides of the top and side rails to form theindoor side walls of the top and side portions of the glazing channel, the indoor side wall of .the bottom portion of said channel .being iormed'by the indoor flange projecting upwardly from the web of the bottom rail.
2. A sectional metal sash frame as set forth in clainr 1,4 including non-metallic material of low thermal conductivity interposed between the top and lside rails of the main frame section and the facing plates associated with said rails toV preventv direct metal-to-metal contact between said railsfand facing plates and non-metallic mate-4 rial of low thermal conductivity interposedvbetween the indoor anges of the bottom rail: and the 'bottom wall of the facing plate groove in which said flanges are tted.
