4 Claims.

This invention relates to window construction and it generally provides one which is air-tight water-tight and adjustable to provide non-draft ventilation.

It is also an object to provide a construction wherein screens may be used, as optional equipment.

A further aim is to provide a construction which avoids the use of the window frame of the box type, enabling, the sides L0 be made simply of boards and the walls to be built directly against the same, giving more window space and enabling the eliminationof calking by proper installation.

Another object is to provide aconstruction wherein the window frame has side members with upper and lower and an intermediate sill to afford an extremely rigid frame.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is an elevation of a window constructed in accordance with my invention, looking at the inner side thereof;

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1;

Figure 3 is a cross sectional view taken on the line 3-3 of Figure 2;

Figure 4 is an elevation of the window taken from the outside or reverse to Figure 1;

Figure 5 is a vertical sectional view taken on the line 55 of Figure 4;

Figure 6 is a cross sectional view taken on the line 66 of Figure 4;

Figure 7 is a cross sectional view taken on the line 7-7 of Figure 4;

Figure 8 is a detail section taken on the line 8-8 of Figure 3, and

Figure 9 is a detail section taken on the line 9--9 of Figure 8.

Referring specifically. to the drawings, wherein like reference characters designate like or similar parts, it will be understood that the window frame and sashes, aside from the glass and screen may be made of wood, metal, composite or of any desired material and in any desired sizes.

The frame generally designated 10 is rectangular, consisting of two sides 11 connected by a lower sill 12, an intermediate sill 13 and an upper or top sill 14. Said sills and side members 11 may be interfitted as shown as at 15 to form an exceedingly rigid construction. The side members, it will be realized, are boards as distinguished from boxes and enable the wall of the building to come practically against any part of the frame, any air space being taken up by plaster, bricks or the like, dispensing with the necessity of calking. The weather boards can run up to the outside frame trimmings which are themselves flush against such frame. It will be understood that a principal object is to eliminate the use of a box type frame and accordingly to avoid the use of pulleys, sash weights, sash cords, sash locks, stops and the like as are necessary in usual constructions.

The lower portion of the frame 10 has a sash 16 therein hinged at the top along a horizontal axis as at 17 to the under surface of the intermediate sill 13, the lower edge of such sash and the adjacent portion of the lower sill 12 as at 18 being outwardly beveled so as to drain off water in an outward direction. Such sash 16 is usually equipped with a glass panel 19. Said bottom sill 12 Has a raised stop 20 integral therewith, and in line therewith on the sides 11 and under surface of the central sill 13, arestops 21 and 22, respectively, against which the window sash =16 tightly fits in closed position, in which position it is held through the engagement of a pivotedhook 23 on the sash with an eye 24 on the stop 20. Said sash 16 is adapted to be held in open positions, through the engagement of a link 25 pivoted to the sash at 26 for both swinging and axial movement on its pivot, so that a key-hole slot 27 therein may selectively engage a series of pins or the like 28 on the stops 21.

At the inner side of the lower portion of the window, two French or casement window sashes 29 are used, the same carrying glass panels as at 30. The casement sashes 29 are ra'bbeted at their upper and outer sides as at 31 and 32 so as to snugly and tightly receive and engage stops 33 and 34, respectively on a cross piece 35 and the sides 111 Said cross piece 35 is parallel to but spaced from the central sill 13 and is fastened to the sides 11, providing a groove 36 between the central sill 13 and cross piece 35. A groove 37 is provided in line with the slot 36," between the stops 21 and 22 and the stops 33 and 34, into which a sash 38 is optionally disposed, the same being equipped with screen material or wire netting at 39. Such screen sash 38 is vertically removable and replaceable through sliding movement upon removal of a cap strip 40, which normally closes the slot 36. The lower inner corner of the sash 38 is rab-.

beted as at 41 to receive beads42 carried by the French doors 29 to form a better air and watertight joint. Said French doors are hinged to the hold such doors in closed position.

When the cap strip 40 and screen sash 38 are removed, non-draft ventilation is afforded since the sash 16 may -be moved to an open position or positions, as previously described, and as shown in Figure 2, the air entering from the bottom under sash 16 and into the room through the slot 36.

The upper surface of the central sill 13 is inclined outwardly as at 46 in order to shed water outwardly and the lower edges of sashes 47 and 48, engageable therewith are inclined for a similar purpose. The under surface of the central sill 13 adjacent the outer edge has a rabbet or groove 49 therein so that water running down the sill 13, must drift therefrom.

Said sash 47 is removable inwardly and carries one or more glass panels as at 50, the lower and upper stiles thereof being cut away as at 51 forming depressions functioning like handles. The lower stile of the sash 47 abuts a stop 52 integral on the central sill 13 and also abuts vertical stops 53 secured to the inner surfaces of the sides 11 and a stop 54 secured to the under surface of the upper sill 14. Such sash 47 is held removably in place by any suitable fastening or latch device as best shown in Figure 9. Such latch devices comprise rotatable buttons 55 having shafts 56 suitably journaled in the sash 47 provided with cranks 57 passing through openings 58 of slides 59 movable into and out of slot 60 provided in the side 11. vAs a result, the buttons 55 may be turned in order to move the slides 59 into or out of the slot 60, enabling the sash 47 to be removed or replaced. Such sash, it will be realized, is held in an air and water-tight relation in the frame.

'I'he sash 48 has a panel 61 therein which may be of glass, or of metallic screen fabric as preferred. Where such panel 61 is of glass, a dead air space is afforded between the same and sash 47 while in cases where it is a screen, it enables removal of the sash 47 so as not-to obstruct the screened space. Such sash 48 is held tightly against the stops 53 and 54 through the medium of pivoted hooks 62 on the stops 53 detachably engaging eyelets 64 on the sash 48. Such sash 48 is removable in an outward direction.

A handle 65 may be provided on the cap strip 40.

Various changes may be resorted to provided they fall within the spirit and scope of the invention'.
