4 Claims. (Cl. 18969) This invention relates to very large and heavy pivoted windows of a' type used in office buildings where larger Windows than usual are required, and in certain industrial buildings. The problem overcome by the invention, as determined by laboratory test, was to so adequately seal the pivoted window, and at the same time permit manual swinging thereof for ventilation, as to withstand rain under wind velocities between 50 and 100 M. P. H., without water infiltration through the window at any point. In our window, in its preferred construction, a double seal of special form is provided, and should any water be driven past the first seal it willbe carried into and downward of the frame, for final discharge at the sill.

The above and other objects of the invention will appear in the following description, with reference to the drawings. i

In the drawing:

Fig. 1 is a view in elevation showing our window with a lower interposed hopper vent, looking at the outside;

Fig. 2 is a view in sectional elevation, with the sash broken away, taken on. the line 2-2, Fig. 1;

Fig. 2a is a fragmentary view through the lower frame member of the window and a hopper vent, being taken on the line 2a 2a, Fig. 1;

Fig. 3 is a horizontal section, partly broken away on the line 3-3, Fig. 1; I

Fig. 4 is ahorizontal section through the hopper vent, being taken on the line 4--4, Fig. 1;

Fig. 5 is a fragmentary view, partly broken away, showing one side of the frame and one half of the pivoted sash, the view being taken on the line 55, Fig. 6;

Fig. 6 is a fragmentary vertical section, taken generally on the line 6-6, Fig. 2;

Fig. 7 is a vertical section through the hopper vent and its sub-frame;

Fig. 8 is a fragmentary view, in perspective, showing at a corner of the main frame the connected sill and a jamb element, with corresponding elements of the upper vent sub-frame therein;

Fig. 9 is a fragmentary view in elevation, being a section view taken on the line 9-9, Fig. 4, except that the hanger is suspended from the jamb;

Fig. 10 is a fragmentary section through one of the areas of the sash showing application of one of the sealing strips; and

Fig. 11 is a similar view showing the action of the strip.

Referring to the drawings, it will be seen that the window frame of the embodiment consists of a sill frame member 1, jamb frame members 2, and a head frame shielded by an angle hood bar 4.

The frame is of special formation being a box-like body, the members intercommunicating throughout. At each wall of the frame, at the sill, at the jamb, and at the head, is a central open slot at S which faces the sash. This slot has a double purpose, as will hereinafter appear.

The sash 6 will extend down to the sill 1 except when a hopper vent is embodied. In the drawings, such a hopper vent is shown. Reference to Fig. 8 will best show the sill and jamb members of a sub-frame for the hopper vent, but the description of the latter will await description of the more primary elements of the window.

Fig. 2 shows transverse sections of the top and bottom sash frame members, and Fig. 3 shows transverse sections of the side frames of the sash.

It will be seen that each sash frame member is formed with two spaced outwardly projecting ribs at each side, these ribs being indicated at 5, the sash members being generally indicated at 6. In each rib 5 is an arrow-head longitudinal slot, the slots at the corners of the sash frame communicating. Into each slot is positioned a twolipped sealing strip of stretchable neoprene or other stretchable material which is very highly resistant to oxidation. The formation of these sealing strips is best shown in Fig. 10. It is desired that the sealing strips extend unbroken from corner to corner, and hence at the corners the strips are vulcanized together. The strips are easily inserted into the arrowhead cavities of the ribs 5. With reference to Fig. 10, the sealing strip 9 may readily be applied by manually stretching it when beginning the insertion. This will reduce the thickness of the arrow-head base of the strip and an area of the latter may then be pressed into the reception cavity of the rib 5, the strip then being released. By progressively stretching the remaining part of the strip, while the inserted part is gripped, it may progressively and easily be inserted in the appropriate rib.

Comparison of Figs. 2 and 6 will show the pivoted arrangements for the window. Into a deep channel 10 in the sill member 1x is fastened by countersunk screws 11 a block 12 having a bearing aperture for pivot stud 13. Fitted in the channelway between the sealing strip holding ribs 5 of the sash frame lower member is a bearing block 14 held in position by countersunk screws 15. The said lowermost one of the two pivot studs 13 extends through the reinforcing rib 6x of the'said lower sash frame member, and near its upper end the pivot stud is formed with a ring groove toreceive a normally split retaining ring 17. To the top of pivot stud 13 is applied a springy hold down clip 18 secured by screw 19 to web 6x.

The upper pivot stud 20 near its lower end projects through the web 6x of the upper horizontal sash frame member and below said web stud 20 is formed with a ring groove to receive a normally split retaining ring 21,

below whichstud 20 is engaged by a springy clip 22 secured to web 6x by a screw 23, Fig. 6.

The upper pivot stud 20 passes through the upper wall of top sash frame member 6 and through a bearing block 24 fitted between the top ribs 5 which hold the appropriate top sealing strips 9. Bearing block 24 is held in position by screws 25. Above bearing block 24 is a heavy bearing block 26 which has a lower central wide rib projecting through slot S of the head frame 3 to the extent of the metal thickness of the head wall. Of course both bearing blocks 24 and 26 are apertured for reception of pivot stud 20; and bearing block 26 may have applied thereto any' convenient suitable means for holding it rigidly in position, such means not being-illustrated.

Comparison of Figs. 3 and 5, showing respectively side and top sealing strips, it will be seen how these strips act in providing a double seal for the pivoted window, and how they act to hold the window in its closed position against an opening force greater than that required to close the window. Fig. 3 shows the position of the side sealing strips when the window is closed, with the inside of the window sashat the-right-hand side of said Fig. 3. When pressure on the window is applied toward the arrow, the sash will be swung on its pivots, but the lips of .each sealing strip will tend .to r everse their angular position and hence will resist said movement of the sash until each outermost strip, as to their directions of movement clear the jambs 2, and the innermost strips, in the direction'of movement, meet the openings S in the jamb and their lips may resiliently swing into vertical position and finally will swing in reverse position relatively to those shown in Fig 3. p

In closing the window, the situation is quite different, and there is less frictional pressure upon the jambs and the head and sill. This is illustrated in Fig. 5. It will be seen that in the closing movement of the sash'the lips of the sealing members are freely swung in one direction, and as the outermost sealing strips reach sealing position, the innermost sealing strips are relieved of pressure by meeting the slotted open passages S. Of course, at those areas of the sill 1x and head 3 of: the frame directly receiving the bearing blocks for the pivots the passageways Sare closed for a short distance. p

As stated, the embodiment illustrated contains a lower hopper vent, The sill 1x forms a parting member between-the pivoted sash 6 and the hopper vent, and the longitudinal channel 10 of sill 1x (see Fig. 2) cornmunicates with the drain openings S of the jamb frame members 2. It will be seen that sill 1x lies between the jambs 2 and may readily be welded thereto. At 29 sill 1x carries a depending stop bar-With which engages a co- .1

acting Web 35, Figs. 2a and 7, on the top member of the hopper vent sash.

For the hopper vent sash the sill 1 and jambs 2 are provided with the sub-frame members shown assembled in the corner fragmentary view, Fig. 8. They are the same in cross section but reversely arranged and relatively offset. The side sub-frame member 30 (see Figs. 8 and 4) has its wide web 31 toward the outside of the hopper vent and its narrow web 32 toward the inside of the vent. The base sub-frame member has its cor responding short web toward the outside and the long web at the inside of the vent.

In Fig. 7 the sub-frame for the hopper vent'sash has not been shown in .detail, although the positions of the base and side narrow and wide webs 31, 32 are indicated.

In Fig. 7 it will be seen that the upper and lower vent sash members 33, 34 are generally similar in that each has a vertically projected narrow web 35 horizontally spaced from a vertically projected wide web 36.

In Fig. 4, the side vertical vent sash members 37, 33 are shown. They are like the top and bottom sash mem bers, each having a narrow web 39 and a wide'web 4%.

When the hopper vent is closed, its vertical narrow webs press against the inside faces of the sub-frame wide webs 31 and directly engage V-shaped sealing strips 41 carried by the latter; and the vertical wide webs 4t) press against the short webs 32 of the sub-frame, bearing directly through V-shaped sealing strips 42.

Also, when the hopper vent sash is closed its horizontal narrow top web'35 bears upon frame member 2') and its horizontal wide'top web bears upon frame member 29x via a V-shaped sealingstrip 42.

Also, when the hopper vent is closed the narrow web of its,bo ttom member bears against the. inside face of horizontal member 31 9f i116 Sub-frame, and wide web.

4i 36 bears upon the outer fa e of the adjacent horizontal member'32'of'the sub-frame, V-shaped sealing strips 43 being interposed.

The hopper vent sash is pivotally hung at each side near its lower end, by parallel swing arms 44 pivoted to the vertical side vent members 38 by pivot stud assemblies 45. At the upper end of each swing arm 44 it is pivoted to the appropriate vertical sub-frame member 30, at 46.

The vent may be latched at its top by rotation of the pull handle 47, at the inner end of which is a latch hook 43 which, when turned up, lies back of a coacting holdplate 49, as shown in Fig. 2a.

With the hopper vent in closed position, as shown in Figs. 2a and 4, release-rotation of pull handle 47 and an outward pull on the latter will cause the lower ends of the vent sash vertical wide webs 40 to bear upon vertical narrow webs 31 of the sub-frame as a fulcrum, and the vent sash will rotate on pivots 45, its top area moving outwardly and its lower end rocking on said fulcrum accordingly; At this point, the vent sash may be given a the embodiments illustrated and described herei n without departing from the spirit of the invention. Thus, while the sealing stripsare preferably carried by the sash, they can be carried by the frame. p I C Having described our invention, what we claim and desire to secure by Letters Patent isas follows:
