7 Claims. (Cl. 2056.4)

My invention relates to window wall construction and has for its primary object the provision of a wall section made primarily of glass and mounting means therefor, so as to provide a wall section of fairly large area which is primarily adapted for use in store fronts, office buildings, school buildings and also, for homes, particularly where thermo-pane glass is used, forming a wall section similar to the large picture windows now in common use.

Another object of my invention is the provision of a glass wall section which can be fitted into old buildings of various types and kinds of wall construction as Well as new buildings which may be made of brick, concrete, frame structure, or the like, and which are made of preformed members which may be cut to length in a shop and the entire wall assembled and installed on location and large glass panes of plate variety installed to close the wall section which glass panes can be set into place from the outside after the frames and inner size members are in position in the Window opening and in case of breakage the outer size members and the glass pane holding means can be removed as well as the broken glass pane and replaced with a new glass pane without disturbing the major portion of the frame and the inside sash member.

Another and further object of my invention is a provision of a glass wall section which can be fitted into various sized wall openings and through the addition oi corner members two glass wall sections can be provided which are at right angles to each other to form a wall section at the front of the building and a side section leading to a doorway or such wall section may be a complete side wall if desired, depending upon the type and character of the building.

Another and further object of my invention is the provision of a window wall section which primarily can be completed ready to receive a glass pane and in which the glass pane can be very quickly and easily inserted without the necessity of disturbing or altering the main frame in which the glass pane is mounted, thereby materially reducing the costs in the erection of glass wall sections in buildings. These and other objects of my invention will be more fully and better understood by reference to the accompanying drawings and in which Fig. l is a cross-sectional view of a wall section comprising a front and side section at right angles to each other,

34, 34 the

outer sash members

46, 46 can be placed in position by deflecting these

outer members

46, 46 sufficiently to enable them to be snapped into place after the glass panes are mounted.

As shown in Fig. 2 of the drawings the side jamb is placed against the wall section 11 while in Fig. 4 a slightly modified form of structure is shown with a hollow door post 86 being positioned against a cover plate 29 covering the open side of the side jamb 16 and is secured to this cover plate by means of

screws

87, 87 and provides for a door support if one is needed in the wall section 11.

The installation and operation of the window wall structure is quite simple and easily understood from the foregoing description and we believe the installation and setting in place of the glass pane sections will also be easily understood. In a proposed installation the window opening in the buiding is first prepared by providing a structure of proper rectangular dimensions and supporting wall structure by erectors of the building structure. Thereupon the sill 17 is placed upon the supporting building structure such as 13 which can be of any approved building form either brick, concrete or frame as may be desired. The top jamb is then placed in position which top jamb is preferably of the same length as the sill for a particular installation and normally is of a sufficient length to span the space to be occupied by the window. Thereafter, a side jamb such as 23 is placed into position and secured to the fixed wall adjoining the window wall opening with the lower end of the side jamb being mounted on top of the bottom rail and the upper end in engagement with the head jamb. The installation at the opposite side of the window depends upon the span of the window or the size of the glass pane or panes which are placed in position to form the window. If the span is a long one such as shown in Fig. 2 of the drawings, a mullion is placed in vertical position which is composed of a pair of inner sash members placed in back-to-back relation with each other and a pair of cooperating outer sash members secured to the mullion thus formed as shown particularly in the cross-section in Fig. 3 of the drawings. If the side of the Window opposite the fixed portion is at a corner then if it is desired to have a glass section at the adjacent side a corner post is provided which is built up in accordance with the arrangement of parts shown in Fig. 4 of the drawings with a corner post forming means to which the .inner and outer sash members can be secured on two adjacent sides of the post. In this particular form, two glass wall sections are provided which are angularly disposed with relation to each other and if the window opening is formed by a wall structure such as shown in Fig. 2 of the drawings of the side section, then a side jamb similar to a side jamb such as 33 is placed in position against the wall and secured thereto which forms a basis for the mounting thereon of the inner and outer sash to hold the glass pane in position. If this wall section is adjacent a door, then a door post illustrated in Fig.4 may be secured to the vertical jamb and the usual frame mounted thereon. If the area to be occupied by the window is small enough to be covered with one pane of glass, and the size of the opening is defined by the walls of the building then vertical jambs are placed between the top jamb and the bottom sill and secured to these side walls to form mountings for the sash members in the same fashion as heretofore described and which extend entirely around the marginal edge of the glass pane forming the transparent portion of the window. Also if instead of the door post intermediate to angularly disposed sections, a wall section or corner support of the building is provided, then a vertical jamb is placed against such section and the necessary sash members mounted thereon in the same fashion as these sash members are secured to other jamb sections heretofore described and the enclosure is ready for the placing in position of the inner sash members. In any event, the inner sash members 34 are placed in position preferably the vertical sash members being first installed with their lower ends resting upon the sill and their upper ends in position against the top jamb and thereafter, a bottom length is placed in position and secured to the bottom sill and the top jamb with each of its ends abutting against the adjacent vertical sash member at each of its ends. When the window opening has thus been prepared by the placing and fixing in position of the inner sash around any window opening the sash is then ready for the installation of the glass pane 38 in that particular section. The glass pane is lifted into position by the workmen with its edges passing slightly beyond the contacting edges of the ribs 36 on the inside sections around the edges of the entire glass pane and is held in proper position by blocks (not shown) resting upon the bottom sill of the window frame. In this position the workmen insert the clips in spaced relation with each other and around the entire marginal edge of the glass pane in any number that may be necessary to hold the glass pane firmly against the inside sash member, these clips being slipped into position around the edges of the glass pane so that the folded ends thereof are placed into the openings between the ribs 45 and the plate portion 41 until the outer edges pass over the rib 42 and are pushed inward so that the lower legs of these clips are firmly seated on the plate portion 41 of the member 34 in which position because the clips are put under tension causes a pressure exerted on the glass pane and automatically set themselves against the under-cut portion 43 on the side of the rib 42. Each clip is thereby placed under tension as it is placed in position and exerts its force upon the glass pane pressing it in an inward direction. The clips are of sufiicient number and are of suflicient strength when placed in position under tension to hold a large section of plate glass firmly in position to form a window and thereafter the outer sash sections of suitable length are merely snapped into position by having the open sides pressed into position over the angular ends 61 and 65 of the clips. Because these clips yield slightly as these parts are pressed into position and the outer sections are opened slightly, the two forces operate to hold the outer sash firmly in position and closes this part of the combination against water, snow and the like, which may be impinged upon the glass surface but do not in and of themselves perform any other function than that merely of being a cover section for this part of the mounting and present a finished appearance to the window section.

If a plate glass section is broken it is only necessary in order to remove the broken glass to first remove the outer sash members and then a part of the clips if the glass pane is to be taken out section by section and the broken glass pane removed as well as the clips and a new glass pane inserted therein by following the steps hereinabove described without in any way disturbing the contents of a window or without any necessity of the workmenigoing inside the building or changing any part of the window sash mounting inside of the building.

'Itis also to be understood that by the use'of substantially three members, 'namelyythe: sills and jambs which are of the same'dimension and of the same form, inner and outer sash members and the clips, a complete wall section can be -installed in any building by merely cutting these various portions to suitable lengths to fit into a pre-determined window opening. Of course, if a double window is desired and a mullion placed in position between the two window panes the mullion can be formed by placing two inside sash members in back-to-back relation with each other and installing the glass and there- :after putting outside sash members in position. Likewise, if a corner is needed to be built, a corner can also be provided with the addition only of the inside corner angle and anoutside angle therefor so that in building almostany combination of window wall section it can be accomplished with a minimum of similar pieces of matelrial to fillly equip workmen for the installation of a particularjob. Therefore, it is only necessary to be supplied with the necessary pieces of material which are duplicates of each other out to suitable length which can be easily and quickly installed in a new building or an old one,

if-desired.
