SASH CONSTRUCTION Filed March 5, 1946 3 Sheets-Sheet 3 Attorney Patented Mar. 18, 1952 UNITED STATES PATENT OFFICE Victor Williamraybrook, Hounslow, England Application March 5, 1946, Serial No. 652,065 In Great .Britain March 8, 1945 'double rebated formation considerably `weakens A.the casement sash and renders it more liable to warp. Further in connection with fixed lights there is a trend towards ldirect glazing into the window frame, to economise timber, instead of, as formerly, providing xed easement sashes to carry the glass. This means that in a window, for openings having the same size, there will be a larger area of glass inthe xed lights (where `there is 4no easement sash) than in the opening' lights (where there is a easement sash) so that neither the vertical nor horizontal glass lines 1n the fixed and opening lights will be in alignment with each other, which is very unsightly. rihe main objects of this invention are the removal, as far as possible, of all these disadvantages.
Accoding to the present invention the rails and Stiles of a easement sash are built up of main members and inner members, suitably held together, the main members normally resting against the external face of the `easement frame, and the inner members which are fitted to the inner perimeter of the main members being only partly inset in the plane of the easement sash, so that they set inwards from the external face of the main members leaving the equivalent of v.a rebate for glass in the easement sash, and project internally and enter a rebate in the window frame.
The rails and stiles formed in this way are preferably of timber so arranged that any tendency in the inner members towarp is as far as reasonably possible at right angles to any such tendency in the main members.
It will be convenient and facilitate this arrangement if the depth of the inner members (that is their dimension at right angles to the plane of the glass) is the same as the width of the main members (that is their dimension parallel with the plane of the glass), whereby the inner and main members can be cut from similar pieces of timber of the same thickness, the dimension they have in common being the thickness of the timber. A
Referring to the drawings which form a part f this 'specicationz 2 Figure 1 is a vertical sectional elevation through a easement window, embodying a transom. l-igureYA 2' -is a vertical ,sectional elevation through another easement window without a transom.
Figure 3 is a vertical sectional elevation through a window sill.
Figures 4, v5, 6 and 7 are fragmentary horizontal sections, looking downwards, showing the invention applied to valter-native types of casement Windows. y
Figure 8 is a AVertical sectional elevation through a similar easement window to Figure 2 lshowing double glazing.
Figure 9 is a vertical sectional elevation through a window frame showing doubleglazing.
Referring first to the figures generally. the parts of the window frame vare vdenoted by heads sills A2, transoms 3, mullions l and lambs 5. In the window frame Aare formed rebates I, adapted either to receive direct glazing or hinged easement sashes. The latter are built up of main members H enclosing approximately vthe same area for glass rI-E as the area of rglass resulting if direct glazing to the Window is used. This vcan be most readilyA seen by comparing Figures 2 and v3, or Figures 8 and 9. The cutting dimensions 'of the glass. can be identical even if `the exposed areas of glass differ slightly. To the inner perimeter faces of these main `members 'are secured inner members l2, by glue'ing or other means, with the assistance of grooves and tongues i3 or similar formations if required. These inner members are set back from the external face of the main members so that they leave in effect glazing rebates, being of the Same width as the glazing rebates in the fixed fra-me, and in depth the inner members extend internally at I4 beyond the internal face of the main members to fit into the rebates in the xed frame. The timber for the inner and main members, it will be seen, vcan be cut so that any vtendencies they may have respectively to warp will be at right angles to one another when the members are assembled, so that the combinedr result will tend to resist warping. Metal angle section members are secured to the sashes or to the frames where desirable, as indicated at 20.
The various figures are intended to illustrate the application of the before-mentioned features of construction to some of the types of windows most commonly required.
Figure 1 shows a window in which there is a transom 3, the light above the transom being a top hung transom light whose hinges are inditends the full height of the window. Figure 3 shows part of a similar sill '2 to that of Figures 1 or 2, but in this case the glass l5 is glazed direct into the frame to form a xed light, and it will be seen that the glass area is substantially the same. In Figure 4 a side hung easement is' shown alongside a fixed light. The side hung easement closes against the centre mullion 4. At
the right-hand side of the iigure, however, it
` YVwill beseen that the glass I5 is xed direct to Vthe Vmullion.
It has been supposed up to the present in this description that the top and bottom rails, the
`Fhangingstile and the closing stile of the easement sash, or where the sash is not side-hung, the two Stiles, the hanging rail`and-tlclosing rail, will all be constructed on the lines described. There are, however, certain circumstances whereY this will need to be modified. Figure 5 shows the case where two side hung easements meet asa pair without an intervening mullion, and here the closing stiles 2| are formed with. angle-pieces 22, or otherwise arranged in any known or convenient manner, so that they can close one on to the other. Figure 6 shows another case where the closing stile 2Ia of a side hung easement adjoins the side of a fanlight, transom light, or top hung easementv 23, where it will be apparent that the members 2|, 23 have to be formed so that they do not foul each other. i
Figures '7 to 9 show theinner members l2 of the sashes, (in the case of opening lights), or the -window framing members (in the case of direct glazing), arranged to carry an additional/pane of glass, the two separate thicknesses of glassVV withv c an air space between them serving as is well known to improve the insulation of the window as re- Vgards heat and sound. Figure 7 is a similar view to Figure 4, showing an opening easement at the left hand side of the iigure and direct glazing in the frame at the right hand side. The inner pane of glass is secured by fillet 24 secured to one of the sash stiles instead of the inward extension I4, 1
so that by removing the iillet 24 the glass can be slid out. In the direct glazing the inner pane` is secured by similar llets 25, one of which may be quickly removed by withdrawing Xing screws 26. The cavity between the two panes of glass may be drained by means of suitable weep holes 21. Figure 8 is a similar view showing a window frame only in which there is this double glazing vand Figure 9 is a similar` view to Figure 3 showingdouble glazing direct to the frame.
Having now described my invention what I claim as new and desire to secure by Letters Patent is:
1. A window comprising a frame having a rebate therein, a easement sash mounted in the frame, the rails and stiles of the easement sash including separate main members and inner members, means securing said main and inner members i together, the main members normally resting against the outer face of the frame and being y wholly located without the plane of the window frame, each inner member being secured to each 5 main member so that the outer face thereof is located within the plane of the easement sash to proyide a rebate for a transparent panel rearwardly'of the outer face of the casement sash and the inner face of each inner member extending l0 inwardly ofthe inner face of each main member for forming a projection entering the rebate in `Vrrv[the window frame.
2. A window construction as claimed in claim 1 wherein each inner member is in facial engagement with the inner side face of each main member and the means securing the inner member and the main member together comprises a tongue and groove assembly on said member.
3. A easement sash adapted to be inserted into a window frame having a rebate therein comprising parallel side rails and stiles and means connecting the side rails and stiles, each of said side rails and stiles comprising a main member and a secondary member adapted to be located in facial engagement with the inner side face of each main member, complemental means on said main member and secondary member to secure said members together, each secondary member being so secured to the main member that the outer face thereof is within the plane of the sash to'provide a rebate for a glass panel inwardly of the outer face of the main' member, and the inner faceof each secondary member projecting beyond the inner face of each main member to form a projection entering the rebate of the window frame. 4. A rail element for use in acasement sash of the type for mounting in a win-dow frame having a rebate therein comprising a vmain member, a secondary member disposed on the inner face of *i0* said main member and extending longitudinally fthereof, complemental means on said main member and secondary member for securing said members together, the outer face of saidV secondary Vmember being located within the plane of said main member to provide a rebate inwardly of the main member, and the inner face of said secondary member exten-ding beyond the inner face of 'the main member to form a proiection. 5. A rail as claimed in claim 4 wherein the complemental means securing the main and secondary members includes a tongue on the main member, and a groove in the secondary member.
