Description

Nov. 18, 1958 Filed Dec. 28, 1955 2 Sheets-Sheet 2 II All! I ATI' EY TILTING WINDOW STRUCTURE Hermann Hess and Albert Maass, Hamilton, Ontario,
Canada This invention relates to improvements in window structure for buildings, of the type comprising an upper and a lower sash arranged independently in grooves in the frame so that when either is displaced it slides past the other.
More particularly the invention contemplates improvements in windows'which have a second or inner frame within the main or outer frame, the second frame carrying the sashes and containing the respective sash grooves. The inner frame is divided, the upper divided portion being permanently fixed to the outer frame while the lower divided portion is pivoted to the outer frame and may be tilted or swung to any non-vertical position. The division occurs at the perpendicular point where the bottom of the upper sash and the top of the lower sash meet when both sashes are fully closed, that is to say, about midway of the height of the window, provided the sashes have equal height.
The upper sash may be fully lowered, whereby both sashes are then in the tiltable portion of the inner frame whereupon the said portion may be tilted, say to a substantially horizontal position, and either of the sashes or both of them withdrawn for convenient servicing, or replacement.
In previous structures difliculty was experienced in overcoming invasion of weather, and the principal object of the present improvement is to provide means for adequately rejecting the elements, in other words, weatherproofing the tiltable portion of the inner frame where it engages the main or outer frame, the fixed inner frame portion, and the sill.
Another important object is to provide means for keeping the sash clear of the sill while the inner frame is tilted, and further, to keep them from improperly sliding from the grooves to the outside rather than from the inside where they are properly removed.
These together with other objects which may later appear are attained by the structure which will be hereinafter more fully described, specifically claimed, and illustrated in the accompanying drawings, in which:
Figure 1 is an outside face view or elevation of a window constructed in accordance with the present invention, and showing the sashes in normally fully closed position;
Figure 2 is a cross-sectional side elevation taken on the line 22 of Figure 1;
Figure 3 is a cross-sectional side elevation similar to Figure 2 but showing both sashes in the tiltable portion of the inner frame, said portion tilted, and one sash (the upper) partially withdrawn from its groove;
Figure 4 is a cross-sectional top view taken on the line 4-4 of Figure 3.
Referring now to the drawing, the main or outside window frame consists of the stiles 10, the head piece 12 and the sill 13. The secondary or inside frame consists of the permanent upper stiles 14 and the tiltable lower stiles 15. The inside frame has the usual vertical pair of sash grooves 16 in each stile, in which the i United States Patent 7 2,860,389 Patented Nov. 18, 1958 upper and lower sashes 17 and 18, respectively, are displaceable.
When the lower or tiltable portion of the inner frame is normally vertical the pairs of grooves 16 in that portion register with and are in alignment with those of the upper or fixed portion, so that either sash may freely slide into any displaced position within the full range of the grooves of both portions. The upper sash may slide fully into the tiltable portion of the inner frame and lie face to face with the lower sash, the lower sash may slide fully into the fixed portion of the inner frame and lie facing the upper sash, that is to say, both sashes may together occupy either the fixed portion or the tiltable portion.
In all positions the sashes are maintained against gravity by friction devices 19, the general structures of which are diversified and are well known in the builders hardware trade.
The lower or tiltable portion 15 of the inner frame is pivoted to the outer frame, as by the opposed pins 20, about midway of its height, that is to say, roughly, at its center of gravity, so that it substantially balances.
The joint or division 21 between the two portions of the inner frame is oblique and stepped as at 22. The oblique joint slopes downwardly and outwardly and thus provides a weatherproof joint. The step 22 enables the bottom strip of the upper sash and the head strip of the lower sash to lie on the conventionally common plane when both sashes are in fully closed or normal position.
When the lower inner portion is tilted, as shown in Figure 3, both sashes having been lowered to occupy it, both sashes or either one separately may be withdrawn from the respective grooves for servicing (cleaning,
painting or repairing). For washing one pane only, the one to be washed may be left in its groove. As a matter of convenience, one sash may be left in its respective upper groove while the lower portion of the inner frame is tilted. The procedure to be followed may vary according to preference considering the service to be performed. In other words, both sashes may occupy the tiltable lower portion of the inner frame when it is tilted, or either of them, and both or either withdrawn after said portion is tilted.
Rests 23 in the grooves 16 of said lower portion are provided proximate the sill 13 for the purpose of sup-' porting the sashes when the lower portion of the inner frame is tilted free of the sill 13. These rests are conveniently in the form of angle pieces, as here shown as an example.
Forming parts of the stiles 10 of the outer frame are hinged wings 24. These wings are on a plane with the main portions of the stiles and with the main portions partially overlap the inner frame and protect the joints of the two frames from the weather. The wings are swung hack free of the inner frame when said lower portion is to be tilted outwardly so that the latter will clear the outer frame.
Similarly arms 25 form part of the inside pieces of the stiles of the outer frame and are swung horizontally across the window above the tiltable portion so that the latter portion properly clears the outer frame.
We claim:
In a window structure having a stationary outer frame including a sill, a divided inner frame set within the outer frame and comprising an upper portion in fixed relation with the outer frame and a lower portion pivoted to and in tiltable relation with the outer frame, sash grooves in both said portions and forming continuous grooves when said lower portion is in normally untilted position, displaceable sashes slidable in said grooves and arranged therein so that either may be in said upper portion while the other may be in said lower portion or so that both may be at once in either portion, the division between said portions being oblique and intermediately stepped, the obliqueness being directed downwardly and to the outside of the window, the stepped portion coinciding with the bottom piece of the upper sash and the head piece of the lower sash when .both sashes are -in normally closed position, rests in the grooves .of said lower portion supportingly engageable with ,the .bottoms of both sashes proximate the sill, hinged wings .forming divided parts of the outside of said outer frame and normally partially overlapping the lower sections of said lower portion to .a height slightly above the tilting axis, said wings being swingingly displaceable outwardly to permit tilting of said lower portion outwardly until the section below the pivot rests on the outside frame member 15 while the section above the pivot rests on the inside frame member, pivoted .arms forming divided parts of the insideof said outer frame and normally partially overlapping the upper sections of said lower portion, said arms UNITED STATES PATENTS 286,584 Boyington Oct. 16, 1883 754,274 Banks Mar. 8, 1904 1,098,695 Stolper June 2, 1914 1,414,583 Rothstein May 2, 1922 2,050,003 Glowacky Aug. 4, 1936 FOREIGN PATENTS 19,618 Great Britain Nov. 1, 1892 720,071 France t Nov. 24, 1931
