SCREEN .IPPARATUS FOR PIVOTED SASHES.,

Application filed April 3, 1925. Serial No. 20,388.

. This invention relates to screens and screen apparatus tor pivoted or swinging sashes.

rlhe main object ot the invention is to provide simple but highly 'eiticientl screen appa ratus for pivoted sashesto be used in combina.-

`tion with upper and lower screens disposed" :tor closing these openings .and thereby ex-l cluding flies and other insects. f

A further object of ,theinvention is to pro vide apparatus, including a means rmounted adjacent the lower edge Hoft the upper sash for closing .the space betweenxthe yupper screen and the outside of they sash, and `means rigidly carried by the sashforiclosing the opening between the lower screen `and the inner side ot the sash. n t

lt is a still Vfurther object to lprovide in suchapparatus, means for closing oit the openings which are `formed at the ends-ofsaid closing means when the sash is swung tocertain positions. t A,

4These and other.objects ot lthe invention will be apparent from the following description made in connection with the accompany ing drawings, whereinv like notationsV refer to similar partsvthrougliout the several views, and in which l y Fig. l is an elevation of the outer side ot a swingingsash mounted -in the sash frame and equipped with apparatus in accordance with this invention; y

Fig. 2 is a vertical `section taken on the line 2 2 of Fig. l with the moved position of the sash indicated bythe dotted lines;

Fig. 3 is a horizontal kfragmentary section taken on the line 3 3 of Fig. l;

Fig. 4 is asimilar section taken on the line 4 4 of Fig. l; and I Y Fig. 5, is a fragmentary verticalsectionot a swinging sash equipped with the preferred lorm ot the invention swung out to openposition.. f v

Referring to the drawings, a standard trame for swinging sashes is illustrated, havlthe angular shoulder 14".

ing the angle bar yside Amembers 6 andi/the similarly constructed Atransverse top yand bottom lmembers, 7 secured therebetween, Weatheringmembers in the term ot' channel 'bars 8 are lsecured on the inner sidesct the side members 6 extending from points below the axis oi the sash to the `bottom of the trame, kalici-ding'k the two weathering points as best seen in Fig. 4, one at either side ot the sash. .A pairot rugged oppositely alined angular brackets 9 are rigidly secured to the inner sides vot the sidemembers 6 of the trame having alined bearings attheir outer ends disposed in the interior sidefot the frame. y-I"ransverse weather strips v7a and 7b are secured at the topk exterior and bottom interior ot the frame, respectively7 to which the rscreen mountingistrips y10 are secured.,V f y v,

A standard'swinging sash, designated as an entirety by the letter Ac omprises the side muntin boards 12the angular bottom and top limitstops, one extending onthe interior and thel other on the exterior ot the 4trame,

respectively, and the .y usual glass panelQC.`

Brackets 1l aresecured at'either side of the ,p

sash yin alinement with brackets' 9` carried bythe frame vand are providedwith `oppof sltely allned bearings 'throughwhich and throughthe bearings and brackets 9, netted bolts llffare secured, pivotally mounting the sash A in the sash frame.r y

Channeled weathering members 13 are secured ateither side of the sash A extending from points slightly above. the axis of said sash tothe top` of the trame, `having the two weathering points adapted .to contact the' sash rframe along the exteriorlandinterior sides thereof.W y y f Abracket 14%, vhaving depending arms yat either end,'isiseou'red across the outer :side of the sash `trame on av line somewhat above the axis of the sash, `to which is secured the strip 14 extending between the side muntin boards 12 of theV sash and having` -theiip standing shoulder 14b on its innen side dis-` posed in close relation to the pane k12C o'lf the sash when the sash is closed. The `top screen 15 is mounted between theup'per weather strip of the sash -frame 7a and `the upper portion of the strip 14 andthe b0ttom edge of said screenextends directly over Arcuate blocks 1G, having a radius-substantiallyequal to the distance between the axis ot the sash and the lower edge of the strip 14, are oppositely alined and secured to the side muntin boards 12 of the sash on the exterior of the sash and cover the space between the side muntin boards and the lower edge of the plate 14 regardless of what position the sash A is swung to, since the arc `of. the outer edge of said blocks is centered on the axis of said sash.

A transversely extendingl rectangular flap 17, having downturned flanges at its outer edge and end portions, extends between the side muntin boards 12 of the sash on the interior of the same and is provided with the longitudinal channel portion 17a at its inner edge, engaging the shoulder 14h and form-V ing a hinge therewith, the .axis of which hinge lies directly beneath and parallel with the bottom edge of the screen 15, as shown in Figs. 2 and 5. When the sash is in closed position, as illustrated in Fig. 2, the flap 17 will be hcldbetween the screen 15 and the pane 12C, with its axis, nevertheless, directly beneath the bottom edge of said screen and, obviously, when the sash is swung, the flap will fall therewith, the outer flanged edge engaging the pane 12c whereby the space be1 tween the arcuate blocks 16 and the lower edge of top screen 15 and the pane 12c will be at all times covered by said liap regardless of the position of sash A.

The lower screen 18 is mounted on the interior side of the sash frame extending from a line slightly below the axis of the sash to the bottom of said frame, the bottom of said screen being held in the strip 10. A transverse plate 19, having a semi-cylindrical main portion, is rigidly secured across the interior sidev of the sash with its inner end in close relation to the pane of said sash and having its semi-cylindrical portion centered about the axis of said sash on a radius approximately equal to the distance between the Y axis of sash A and the top of the lower screen 18. Obviously, since theV semi-cylindrical portion of plate 19 is so centered, the space between the interior side of the pane 12c and the top of the lower screen 18 willat all times be covered when said sash is' swung, and since the pivots of the sash are on the interior side of the sash frame, plate 19 will be swung between the sides of the sash frame having its ends covered thereby.

In certain positions of the sash, however, the ends of the flap 17 will not be covered by the arcuate blocks 16 and small apertures would be formed were it not for the vertically swinging depending plates 20 pivoted to the outer sides of the arcuate block 16` adapted to have their lower edges engage the top edges of the limit stops or weathering members 8. By means of these swinging plates 2O all passages at the ends of the flap 17 are closed regardless of the position of the sash.

Y From the above, the operation of the device verse plate 19 will be swung with the lower edge of its cylindrical portion engaging the top edge of the lower screen 18. The ends of the flap 17 will be covered by the arcuate blocks 16 and the depending swing-plates 20. It will, therefore, be seen that the sash may be swung open to any position without leaving apertures for flies or insects to gain entrance into the interior of the room.

From the foregoing description, it will be apparent that simple but highly efficient apparatus has been invented for use in connec-y tion with pivoted sashes and screens therefor.

Extensive actual usage has proven the in" vention to be highly successful for the purposes intended.

1t will, of course,.be understood that various changes may be made in the form, details, proportions an'd arrangement of parts without departing from the scope of the invention, which, generally stated, consists in the apparatusas shown and described and defined in the appended claims.

That is claimed is:

1. In swinging sash provided with a screen, apparatus for closing the space between said screen and said sash comprising a transverse flap hinged adjacent the lower edge of the screen and held against the pane of said sash, and a pair of narrow, spaced closure members fixed to said sash at the ends of said flap extending in al plane normal to the pane of said sash and having an outer edge concentric with the pivot'of said sash for closing the space between the ends of said plate and said sash.

2. In swinging sash provided with a screen, apparatus for closing the space between said sash and said screen having in combination a rigid flap swingably j mounted from the lower edge of said screen withits free end held against the pane of said sash by gravity, narrow closure members carried adjacent each longitudinal edge of said sash at right angles to the pane of. said sash and having arcuate outer edges concentric with the pivot of said sash, said edges being disposed tangential to the lower edge of said screen and plates loosely pivoted to said closure members extending between the longitudinal edges of said sash and its sash frame.

3.1n swinging sash provided with a screen,
