WEATHER STRIPPING MEANS FOR wmnow 1 Earl v. Flaherty, Hamiltom ohio i (2405 Middle River Drive, Fort Lauderdale, Fla.)

Filed Aug. 4, 1959, Ser'. No. 831,652

- 4 [term-5 ROTATABLE This invention relates torotatable or reversible windows 'ice 9 and 10. In accordance with the invention, the sash 6 is pivotally mounted on vertically disposed pivot pins 11 and 12 so that the sash may be rotated relative to the frame in either direction, thereby permitting the sash to be readily reversed for cleaningpurposes and the like.

It will be understood, of course, that the sash 6 will mount and has to do with the provision of weather stripping means for such window. 7 t

In the conventional reversible window, the sash is vertically pivoted at its center so that it maybe rotated to reverse its position for cleaning purposes, thereby permitting both sides of the window glass to be washed from r the inside of the, building. One of the principal difficulties with window structures of this character is the provision of suitable weather stripping means which will eifectively seal the window when in closed position and yet permit the seal to be readily released so that the window may be reversed for cleaning purposes. While numerous forms of sealing means have hitherto been proposed, they have been generally unsatisfactory in that they are unduly complicated, difiicult to install and operate, and generally quite expensive both to install and to maintain.

Accordingly, a principal object of the instant invention 7 means which can be readily fabricated as a unit utilizing interchangeable parts.

The foregoing together with other objects of my invention which will appear hereinafter or whichwill be apparent to the skilled worker in the art upon reading these specifications, I accomplish by that construction and arrangement of parts of which I shall now describe an exemplary embodiment.

Reference is now made to the accompanying drawings wherein:

Figure 1 is an elevational view with parts in section of a Window unit incorporating Weatherstripping means in accordance with the invention.

one or more panes of glass 13.

While window structures of the general character just described have hitherto been proposed, the major difiiculty encountered has been in the provision of suitable weather stripping means eifective to secure a tight seal between the frame and sash and yet permit the sash to be readily released for reversing movement. In accordance with the instant invention, a tight yet readily releasable seal is effected between the jambs of the frame a'ndthe side rails of the sash by means of the rotatable sealing members 14 positioned in vertically extending recesses or pockets 15 formed as a part of the jambs 4 and 5. These pockets, as best seen in Figures 2 and 3, are essentially semi-circular in cross section and are preferably formed as integral parts of the window frame.

The sealing members 14, as best seen in Figure 1, are each rotatably mounted in the pockets 15 by means of vertical pivot pins 16, the arrangement being such that the axis of rotation of each sealing member coincides with the longitudinal axis of the pocket in which it is received.

The sealing members themselves are of generally cylindrical configuration, although they each have a flat side 17 which, as will be evident from Figure 3, terminates substantially coextensive with the innermost edges of the jambs 4, 5, when the sealing members are rotated to the sash release position. However, when the sealing members are rotated through substantially 180, i.e. to the sash sealing position illustrated in Figure 2, their cylindrical sides will project beyond the edges of the pockets for contact with the side rails of the sash.

As will be evident from Figures 2 and 3, the side rails of the sash are each formed to define a longitudinal recess 18 which is arcuate in cross section and complementary to the pockets 15. That is, each of the pockets 15 and the corresponding recess 18 define opposite wall surfaces of a cylinder the longitudinal axis of which coincides with the axis of rotation of the sealing members 14.

The sealing members 14 are each provided with a covering of vinyl plastic or wool pile weather stripping mate- I rial 19 which, as the sealing members 14 are rotated, is

selectively brought into contact with the pocket 15 and the recesses 18. In a preferred form of the invention, the Weather stripping material 19 is in the form of a vinyl plastic having a plurality of spaced apart, longitudinally extending resilient vanes 20 extending around at least half the circumference of the sealing members. When the sealing members are in the sealing position of Figure 2, it will be evident that a plurality of the vanes 29 make sealing contact with the recesses 18, and at the same time the endmost fingers make sealing contactwith the wall surfaces of pockets 15, thereby sealing the window structure both against the circulation of air between the sealing members and the sash, and also between the sealing members and the walls of the pockets 15 which, unless sealed, would permit the primary seal at the sash to be bypassed. When the sealing members are rotated to the release position of Figure 3, all of the fingers are brought into contact with the pockets 15 and the flat sides of the sealing members face the side rails of the sash but do not materially project beyond the inner edges of the jambs, the sash thus being freed for reversing movement.

The weather stripping material may be readily fitted to the sealing members. and replaced by means of the locking plate 17a which serves to clamp the weather stripping maetrial to the sealing member.

As seen in Figures 1 and 4, the sealing members are adapted to be rotated by means of a crank handle 21 operative through worm gear 22 to rotate shaft 23 which acts through spur gears 24 to rotate the lowermost pivot pins 16 mounting the sealing members.- It will be obvious that the means illustrated for rotating the sealing members is exemplary only and that various known mechanical expedients may be employed for rotating the sealing members either singly or jointly as desired.

It has been my experience that the critical sealing areas in reversible windows are between the jambs and the side rails of the sash; and that the top and bottom rails of the sash can be satisfactorily sealed by stationary sealing members of the character illustrated in Figures 4 and 5. As seen therein, the

horizontal rails

7 and 8 are of identical construction to the side rails 9 and 10 in that they incorporate recesses 18a; but in this instance the recesses 18a are utilized to mount weather stripping members 25 which are of more or less U- shape in cross-section and preferably formed of a resilient material such as vinyl plastic, rubber or the like. The weather stripping members have projecting flanges 26 which make sealing contact with the header and sill of the frame. It will be apparent that the weather stripping members 25 will permit free rotation of the sash and yet, when juxtaposed to the window frame, will make sealing contact therewith. If desired, the sill 2 may be provided with a drain gutter 27 having an outlet tube 28 extending through to the outside of the window frame.

While in the preferred embodiment of the invention illustrated in the drawings, only the side rails of the sash are sealed by means of the rotatable sealing member just described, the upper and lower rails being sealed to the header and sill by the resilient sealing members 25, it will be apparent that other forms of sealing members may be substituted for the members 25 inclusive of rotatable sealing elements of the character utilized to seal the vertical rails of the sash.

The window structure just described may be readily fabricated from extruded aluminum, stainless steel, or the like, and it should be apparent that a minimum number of parts are required in that all of the rails are of identical construction, as are the jambs of the frame. The entire structure may be prefabricated and shipped as a unit ready for installation. Once installed, maintenance is relatively simple in that the rotatable sealing members may be readily removed and the weather stripping material replaced in the manner already described.

Modifications may be made in my invention without departing from its spirit and purpose. For example, while the rotatable weather stripping means described will find particular utility in rotatable windows its utility is not so limited and the rotating sealing units may be installed in doors and other applications wherein a tight yet releasable seal is desired. Thus a pair of such units could be installed in the frame of a revolving door for use when the door is locked.

Having thus described my invention in an exemplary embodiment, what I desire to secure and protect by Letters Patent is:

t 1.
