2 Claims.

lljhis invention relates to closure or window construction, the primary object of the invention being to provide a closure or window structure wherein the -sashes are constructed of plastic material and arranged so that a binding action is set up between the sashes and their guides, to cause the sashes to be retained in their various positions of adjustment, by the frictional contact between the sashes and guides.

Another object of the invention is to provide sashes so constructedy that the ends thereof will overlap, to the end that a number of these sashes may be used in a window structure and the upper sashes lowered to permit of ventilation without the necessity of moving the lower sashes.

Still another object ofthe invention is to provide sashes that operate in guidV s which are pivotally supported within window frames, to the end that the sashes may be swung inwardly to facilitate cleaning thereof, and eliminating the 'necessity of the person cleaning .the sashes working from the outer side of the building.

With the foregoing and other objects in View which will appear. as kthe description proceeds, the invention consists of certain novel details of constructionand combinations of parts hereinafter more fully described and pointed out in the claims, it beingunderstood that changes may be made in the construction and arrangement of parts without departing from the spirit ci the invention as claimed.

Referring to the drawings;

-eXtend inwardly from Figure 1f) is a transverse sectional View through a modied form of guide.

Figure 11 is a sectional View modified form of guide. o c I Figure 12 is a sectional view through a window frame, showing cooperatingy sashes, v.mounted within guides in the frame. v f Figure 13 is a fragmental sectional view through a modified form of guide. Figure 14- is ya fragmentl perspective view illustrating a still further ferm of sash:

Referring to the drawings in detail, the sash as shownr by Figure 2 of the drawings, comprises lower sectiens 5 and upper sections 6, the

sections

5 and 6 being constructed of translucent plastic material, curved longitudinally and formed intermediate their ends, with ribsor -enlargements 'I adapted to engage the pins 1f, that the guide bars, in which the sections 5 and move. f These sections are sli'dably mounted in guideways e formed in the guide bars 8, the guideways t being arranged in'parallel relation with respect to each other, and provided with depressions 8 to accommodate the ribs or 'enlargements thereby Vsecuring the sections 'against movement under normal conditions.

These-guide bars have upper and lower pins lll, which are positioned in openings formed in the side members ofthe window frames, certain of the pinsof the guide bars acting'as pivots for the guide bars and vsashes mounted therein, should it ybe desired to swin'g'th'e sashes and their guides inwardly to ypermit them t'o 'be cleaned with facility. The lower edges of the lower sections 5 are extended outwardly, providing flanges Il, while the lower edges of the upper sections f6' are'ex tended rearwardly at l2, providing flanges that bear against the adjacent lower sections'- to set upa binding action and provide a water-tight connection between the sashes.

Since the sashes are curved, it will be seen that a binding action is set up between the sashes and their guides to hold the sashes in their pcsitions of adjustment without the` necessity of providing weights, springs or the like.

Therupper edges of the upper sections 6 are also extended rearwardly to rest against the upper bar of the window frame, as shown by Figure 3 of the drawings.

As shown by Figure through a further 'l of the drawings, guideways are provided in the opposite side members of the window frame, the guide members having parallel guide ways for the'reception of the side edges of the sashes. The sashes in this form of the invention have interlocking flanges arranged along their upper and lower edges so that by raising and moving the uppermost sash section to the top of the window frame, the cooperating langes which are indicated by the reference characters I3 and I4, Will engage to move the sashes to their extended positions. Due to this construction, a tight connection is provided between adjacent sashes, and the upper sections of the sashes may be lowered without disturbing the lower sash sections, to provide ventilation.

As shown by Figure 8 of the drawings, a further modied form of sashes and sash supports is shown. In this form of the invention, the sashes are indicated by the reference character I5 and have cooperating flanged ends I E, there being provided a series of sashes arranged to provide what might be termed storm sashes.

The sashes operate in movable guide bars' II that are fitted against the inner edges of the Window frame.

As shown by Figure 6 guide bar 21 is formed with ribs 9', forming guideways 28, the guide bar 27 being curved transversely and constructed of semi-rigid material so that when pressure is directed thereto by the sashes operating within the guideways 28, the guide bar will ex and be caused to closely engage the frame in which it is positioned, providing an air-tight connection between the guide bar and frame. Pins 29 extend inwardly from the guide bar and are adapted to be fitted in the openings formed in the frame, removably and pivotally mounting the guide bar within its frame.

In Figure 9 I have indicated a window frame of the usual and well known construction, altered by providing which a guide bar, such as indicated at II in Figure v10, may be held. In Figure 9 the reference character 3| indicates the usual sash members, which may be removed and replaced by guide bars, such as forming the subject matter of the present invention. A

The reference character I8 indicates one type of window guide member, wherein a vertical flange I9 is provided'along one edge thereof to provide a stop for the guide bar '20 supported thereagainst.

Still another form of my bar is shown in Figure 12 of the drawings, the sashes 2I interengaging at their ends, so that as the sashes are extended, close fits will be provided between the

anges

22 and 23 thereof. To further provide a Weather proof connection between the guide bars 24 and the sashes mounted therein, a weather strip 25 is provided along the front edge of the frame.

of the drawings, the

the blind stop 30, againstr As shown by Figure 14, the sashes may be constructed by corrugating the same, thereby greatly strengthening the sashes. The sashes in this form of the invention are formed with laterally extended anges that slide in grooves of guide bars, not shown.

While I have shown and described the sashes as constructed of plastic material, it is to be understood that the material of which the sashes are constructed, may be of any desired nature, providing the sashes are resilient to set up a binding action within the guide bars in which the sashes are mounted.

Having thus described the invention, what is claimed is:

1. In a closure construction, a closure frame having openings arranged adjacent to the ends thereof, guide bars having a plurality of parallel straight sash-receiving grooves fitted within the frame, pins extending from the guide members, fitted in said openings removably sestructed of translucent semi-rigid material curved longitudinally, the curved side edges of the sash members being tted within the straight sashreceiving grooves of said guide receiving members, straightening said sash members, setting up a binding action between said sash members and the walls of said grooves, holding the sash REFERENCES CITED The following references are of record in the file of this patent: l
