Application filed March 16, 1925. Serial No. 15,812.

To all whom it may concern:

Be it known that I, MAX RACHLIN, a citizen of Russia, and resident of the city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Window Screens,

in parallel planes from one another, so that Insects may readily enter the room between the overlapping portions of the screen fabrics. It has been proposed heretofore to provide means'for preventing passage of insects between the, frames. This means is usually in the form of a vertically extending 'bar which forces the fabric of one frame against the inner vertical member or stile of the other frame. This bar has heretofore been rigidly attached at both of its ends to the window screen, so that, when the sections of the latter are moved in relation to one another for purposes of adjustment,.the said bar, in bearing against one of the screen fabrics, is apt to injure the latter, attention being called to the fact that the fabrics bulge in time, so that not only will the said bar wear away the fabric by friction but tear the same in case it bulges out excessively.

The main object'of the present invention is to provide 'means for forcing the screen fabric of one frame section into engagement with the inner stile member of the other section, which overcomes the difficulties above referred to. 1

Another object of the invention is to provide a device of the character discribed which is simple in construction, efficient in operation, durable in use'and which is capab e of manufacture on a commercial scale,

or in other words one which is not so difficult to make as to be beyond the reasonable cost of such a contrivance.

With these and other objects in view,

which will more fully appear as the nature. of the invention is better understood, the

same consists in the combination, arrangement and construction of parts hereinafter described, pointexl out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of theinvention.

A. few of "the many possible embodiments of theinvention are, illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a window screen constructed in accordance with the present invention; Fig. 2, is a section taken on line 2-2 of 'Fig. 1, on a larger scale; Fig. 3 is a section taken on line 3-3 of Fig.

1, also on a larger scale; Fig. tis a section 7 taken on line 4.4= of Fig. 1, also on a larger scale; Fig. 5 is an elevation similar to theone shown in Fig. 1 of the drawings of a modification of the invention; Fig. 6 is a section taken on line 6-6 of Fig. 5, on a larger scale; Fig. 7 is an elevation'similar to the one shown in Fig. 1 of the drawings of a further modification of the invention; Fig.

8 is a section taken online 88 of Fig.

on a larger scale; and Fig. 9 is a section similar to the one shown in Fig. 8, with certain elements of the device in other positlons.

Generallyspeaking, the invention consists in pivoting to one of the horizontal rails of a window screen frame section, in spaced relation from but in alignment withthe inner stile of the said frame section, one end of a bar, the other end of which is adapted to be engaged with anddisengaged from the opposite horizontal rail of the other frame section; said bar bein adapted to bear against the screen fabric of the last-mentioned, frame section.

Referring now first to Figs. 1 to 4, in-' elusive, of the drawings, the numeral 10 indicates one of the sliding sections of the window screen, and the numeral 11 the companion section thereof. The section 10 comprises two

stiles

12 and 13, connected by a lower horizontal rail 14' and an upper horizontal rail'15'. In a similar manner the frame section 11 comprises two stiles 16 and-17, connected by a lower horizontal rail '18 and an upper horizontal rail 19. Across these two frame sections are stretched

screen fabrics

20 and 20, respectively. The two frame sections may be made of any suitable material and may be of any suitable construction, the horizontal rails of one frame section overlapping those of the other section and being slidably connected. In the case illustrated in the drawings, the stiles and rails of each frame section are'provided with channel beads 21 througho'utl their lengths, the screen fabric ofeach frame section having its marginsextending into the channels of the said section and being held in place by a locking member 22, inserted into the channels. It is obvious that any other suitable construction may be provided for fastening the screen fabrics to the frame sections, the one herein described being disclosed for purposes of illustration only. It is, however, essential that the stile 13 of the frame section 10 be provided with ahead 21, projecting toward the screen fab-- ric 20' of the frame section 11 into contact with the fabric from the lower rail 18 to the upper rail 19 of the last-mentioned frame section. As appears from Figs. 2 to 4, inclusive, of the drawings, the screen fabrics of the'two frame sections are spaced from one another, they extending in parallel vertical planes.

To the lower rail 14 of the frame section 10 is attached in any suitable manner a clip 23, extending around the lower rail 18 of the frame section 11, the arrangement being such that'the said clip does not interfere tion 11 on the frame section 10. To the clip is pivoted at 24 a bar 25, preferably,

' made of metal.

This bar is bent at its lower end inwardly toward the fabric 20 onthe frame section 11 and extends in contact with the said fabric to the upper rail 19 of the frame section 11. At its upper end the said bar is bent outwards, as shownat 26, and thence upwards as indicated at 27., A finger piece 28 is attached to the bar. The portion 27 of the bar is adapted-to be seated in a longitudinal groove 29 in the u per rail 19 of the frame section 11, the sai groove extending from stile to stile of said frame section. The bar 25 is somewhat springy, so that, when it is disengaged from the groove 29', it springs away from the fabric 20', as shown in dotted lines in Fig. 3 of the drawith.

en the elements are in the positions shown in full lines in Figs. 1 and 3 of the drawings, the bar 25 contacts throughout its length with the fabric 20 of the frame section 11, forcing the same into engagement with the stile 13 of the frame section 10, and thereby preventing the passage of'insects between the fabrics of the frame sections into the room. Whenever it is intended to adjust the screen, that is to say to slide one section thereof upon the other, the bar 25 is taken hold of by the finger piece 28 and shifted around its pivot 24 into the position shown in dotted lines in Fig. 1 of the drawings. moves away, owing to its resiliency, from the fabric 20, so that a sliding movement of the two frames in relation to one another will be permitted without the bar wearing away the fabric 20.

The modification illustrated in Figs. 5 and 6 of the drawings differs from the one above described in that the bar, which forces the fabric of one frame section against the stile of the other frame section, is detachably carried by the frame section 11. This bar is indicated in the drawings by the numeral 30, it being, preferably, made of a yielding material. Adjacent its ends the said bar is provided with finger pieces 31, which are shown as being made integral with the bar, although this is not essential. The lower rail 18' and the upper rail 19' of the frame section 11 are provided each with a longitudinal groove 29. in which the ends of the bar 30 are adapted to be seated.

When the bar is in position upon the frame section 11', it forces the fabric 20 When thebar is then released, it

of the frame section 11' into engagement moved from the frame section 11, to be put again in position thereon after "the adjustment has been made.

The modification illustrated in Figs. 7 to 9, inclusive, of the drawings differs from the one described in connection with Figs. 1 to 4, inclusive, in that, instead of one clip, there are two clips provided. One of these clips, denoted by the numeral 32, is attached to the lower rail 14' of the frame section 10", and the other one, denoted by the numeral 33-, is secured to the upper rail 15 of the frame section 10". These clips extend around the upper and lower rails of the frame section 11", permitting of a sliding movement of the two frame sections in relation to one another. Each of'these clips is which is slidably fitted a bar 35, adapted to bear against the screen fabric 20 of the frame section 11 and to force the same against the inner stile 13" of the frame section 10". A spring 36 is interposed between each end of the bar 35 and the adjacentrail of the frame section 11", said springs having a tendency to force the bar 35 out of engagement from the screen fabric 20'.

Upon each clip is p-ivot'a'lly mounted a lock-,

If it is intended to adjust the frame secprovided with side flanges 34, between.

fabric 20', against the action of the springs tions of the screen in relation to one another, the locking members 37 are shifted around their pivots soils to be disenga ed from the bar 35. The springs 36 are t us free to act, freeing the' bar 35 from the screenfabric. After the proper adjustment has been made, the locking members are moved on their pivots into engagement with the bar 35, causing the same to bear against the screen fabric of the frame section 11".

While herein specific constructions have been described for permitting adjustment of the screen frames in relation to one another, any others may be used without departing from the invention which lies main-f ly in the provision of a bar adapted to force the screen fabric of one frame against the inner stile of the other frame, said bar being disengageable from said screen fabric so as .not to bear against the same when adjustment of the frame sections is to be made.

What I claim is 1. A window screen comprising two frames slidably joined together, each frame consisting of two stiles connected by atop rail and by a bottom rail and a screen fabric stretched across the same; a clip secured to the bottom rail, of one of said frames in alignment with its inner stile, said clip extending around thebottom rail of the other frame, a bar pivoted to the free end i of said clip adapted to bear against the screen fabric of said last-mentioned frame and to force said fabric into engagement with the stile of the-frame to which said clip is secured, and coacting means on the free end of said bar and the top rail of the frame against the fabric of which it bears for separably fastening the free end of said bar to the last-mentioned top rail.

2. A window screen comprising two frames slidably joined together, each frame consisting of two stiles connected by a top rail and by a bottom rail and a screen fabric stretched across the same, 'a clip secured to the bottom rail of one. of said frames in alignment with its inner stile, said clip extending around the bottom rail of the other frame, the top rail of said last-mentioned frame being provided with a lon itudinal groove, and a bar pivoted to the rec end of said cli adapted to bear against the screen fabric of said last-mentioned frame and to force said fabric into engagement with the stile of the frame to which said clip is secured when the free end of said baris seated in said groove.

3. In a window screen according to claim 1, said bar being made of yielding material so that it springs away from the adjacent screen fabric when said coacting means are disengaged.

4. In a window screen according to claim 2, said bar being made of yielding material so that it springs away from the jacent screen fabric when its free end is disengaged from said groove.

5. A window screen comprising two frames slidably joined together, each frame consisting of two stiles connected by a top rail and by a bottom rail and a screen fabric stretched across the same, and a bar adapted to bear against the screen fabric of on of said frames and to force said fabric into engagement with the stile of the other frame, said bar being disengageable from said screen fabricto-permit adjustment of said frames in relation to one another.
