Application filed April 9,

To all whom it may. concern:

Be it known that 1, CHARLES H. GEORGE, a citizen of the United States of America, and a resident of Framingham, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Ventilating Attachments for Vindo'ws, of which the following is aspecification. i i

This invention relates to ventilating attachments for windows. An object of the invention is to produce such a device that may be made decorative in effect as well as being useful in its function as a ventilating means, and cheap to manufacture Another object is to produce a ventilating attachment that may be speedily applied to or removed from its operative position and which may be compactly rolled for storage when not in use.

A furtherobject of the invention is'to produce an attachment that. is applicable to windows of different widths and which when once applied for use holds itself in such position without the aid of external fastening means. i y

A still further object is to provide a ventilating attachment that is-so arranged as to greatly reduce the entry of dust and soot to theroom or chamber through the windows having the attachment applied thereto.

Formerly, forv this purpose, a boardwas used which had to be especially fitted to the window to which it was to be applied and fastening means usually mounted on the window casing had to be supplied which were unsightly and damaging to the said casing;

Furthermore, these boards could not be conveniently stored as compared with. the present device, and they had no provision for the elimination or partial elimination of the entry of soot and dust to the ventilated room. t y 1 It is not the intention to limit this invention to theprecise construction and arrangement herein shown as it is obvious thatthe same may be altered or changed without departing from the spirit and scope of the invention. I

To the attainment of the above objects the invention consists in certain novel features of construction and arrangement of parts which will be fully understood by reference 1921. SerialNo. l60,019.

to the description of the drawings and the claims hereinafter given.

Of the drawings:

Figure 1 represents a view of a window i and its casing with the invention applied thereto.

Figure 2 an'enlarged view of a portion of the attachment as seen in Figure 1 partially broken away to more clearly illustrate its construction.

Figure 3 is an enlarged section on the line ,3-.3 Figure 1.

cost of manufacture. i

' The window casing 10 and the sliding sashes 11 and. 12 are or may be of any usual or suitable construction. In a great major ity of instances the casing 10 extends outwardly from the wall 13 whichconveniently forms .a shoulderor abutment 14 to receive the anchor members 15 and 16 forming part of the ventilating attachment 17'.

Intermediate the members 15 andv16 is a length of material 18 capable of being rolled upon itself, preferably of textile fabric which may or not bepainted, sized or other-- wise treated to make it dust and moisture proof or for the purpose of decoration. Suitable pockets 19 are formed in the material 18 to receive the rods or batons 20 while otherreceptacles 21 are provided to receive the cleats 22 which are secured to. the an chor members In any suitable manner. The

said cleats 22 have cutaway portions as at 23 to receive therein the rubber "bands 24 whichalso embrace the rods/20 as plainly disclosed in Figures 2 and 4 of the drawings.

. The materiaLlS" between the rods or batons 20-and the cleats 22 is considerably in excess in length, to the length of the bands 24 when not stretched, said bands beingenclosedina loose pocket 25 formed in the material 18 and which supports the mate rial atthat portion thereof which'isf preferably not under tension at any time.

It will be readily seen that when the bands 24: are not stretched they will cause the rods or batons 20 to approach the cleats 22 or vice versa, and in so doing the material 18 will be caused to pucker or gather in such manner that when the bands are stretched the material 18 will be deprived of some of its slack, varying of course according to the amount of stretch given to the bands. Preferably the amount of slack at 183 is greater than can be taken up by the extreme stretch of the bands, as the gathered material gives a pleasing effect to the eye. It will also be understood that While two sets ,of bands, rods and cleats are herein shown, one set of each would suffice so far as the in ention 1s concerned. i

It Will also be understood that the anchor I members, rods and cleats may be made of any suitable shape, size or material.

To apply the device to a window, one of the anchor members as 15 is adjusted to abut theshoulder let, as seen at the left in Figure 1, and the member 16 is moved to the right and similarly adjusted to abut the shoulder at that side. During this movement the bands 2-4 will have been stretched a sufficient amount to assure the retention of the anchor members 15 and 16in their adjusted positions, while at the same time causing tension to be applied to the material at 18, which gives it a board-like effect.

Viewing Figure 3 it will be noticed that the upper portion of the material 18 terminates in a downwardly and. outwardly turned edge 26, while the lower portion terminates in a skirt-like edge 27' adapted to snugly contact with the window sill in such manner as to close any opening that might otherwise occur between the material and the sill, to thereby prevent the passage of soot or dust therethrough. In said figure the arrows indicate the passage of air beneath the opened sash 12, which on its upward course will meet the inclined edge 26 which will collect the soot and dust and prevent its passage into the room.

It is obvious that an attachment such as just described would be applicable to windows of different widths and therefore need It Will be readily understood that in the absence of a protruding window casing the anchor members may be adjusted to cleats or similar devices which may be secured each side of the window and may be ornamental in appearance.

Having described the invention I claim:

1. In a device of the class described, a Window casing; anchor members adapted to temporarily and removably engage said casing; a strip of substantially non-stretchable material intermediate said members; a strip of material so arranged as to contain an appreciable amount of slack therein at each end of said non-stretchable material; and means to cause tension to be exerted on said non-stretchable material and take up slack in said second strip of material upon adjusting said device for use.

2. In a device of the class described, anchor members adapted to be removably adjusted to a window at each side thereof; a

strip of flexible material intermediate said members, a portion of whlch 1S arranged. to be placed'under tension when in use, batons at the ends of said portion; other portions of.

said material so arranged as to present an appreciable amount of slack therein; and yielding means attached to said batons and anchor members adapted to create tension on said flexible material and cause said anchor members to closely adhere to their adjusted positions at the window sides.

3. In a device of the class described, a window casing, anchor members adapted to engage said casing at each side of the window; a strip of flexible material adapted to be rolled upon itself intermediate said. members, aportion of said strip being adapted to have tension applied thereto, said portion having batons at the ends thereof; other portions having slack therein and not subject to tension; and stretchable bands adapted to apply tension to a certain portion of said strip and not to others where slack is required, said bands being intermediate said members and said batons and so arranged as to support said slack portion against sag and cause said members to closely adhere to said casing.

t. In a device of the class described, a window casing; anchor members adapted to temporarily and removably engage said casing; a strip of material intermediate said anchor members, the major'portion of which is normally under tension, while other portions are slack, and having an edge thereof folded back upon itself to thereby form a baflie; and means whereby said members may be positioned for use, various distances apart.

Signed by me at Boston this 4th day of April, 1921.

CHARLES H. GEORGE.
