i "Application filed April 13,

My invention relates to wind deflectors and refers part-icularlyto devices of this character adapted to be positioned-with n a window frame and to deflect the air passing material'for the production of wind deflectors. as it is cheap, can be shipped in-flat form and easily bentinto the desired shape, is light and can be made water proof by means of paint or varnish. i h

"Corrugated cardboard, however, is not practical for the purposes indicated as wind deflectors must be attached to window frames, preferably by means of nails, or screws. The formation of corrugated cardboard is of such character. that the headsof the fastening means are forcedinwaidly of the cardboard in attaching the latter to a window frame, thus preventing a "tight joint-ure. Y

. Another undesirable feature of corrugated cardboard for this purpose that the cardboard is liable .to tear awayrfromthe fastening means, any pressure or strain hav.- ins; a tendency to pull the naih or screw, through the cardboard, thus destroying the usefulness of the device. 1 Q

My invention allows the use ofcorrugated cardboard for wind deflectors asit overcomes the objectionable properties above described and completely prevents the entry of the heads of the nails, or screws from entering the cardboard, thus allowing firm connections between the device and the windowv frame and also completely overcoming the possibility of a cardboard tearing away from the fastening means because of strains, or stress, brought to bear upon the device.

My device comprises a corrugated cardboard Wind deflector, the fastening portions of which carry a metallic strengthening member, or strip, having holes therein through which the fastening means may be inserted. The inner edge of the strengtheningmeans carries a plurality of teeth inserted within the cardboard. Any strain, therefore, upon the device is not brought to bear simply upon the nails, or screws, used forfastenin pur JOSQS. thus tendin to'tear b a I the fastening means through the cardboard, but such strain is supported bythe plurality of teeth and hence distributed-over the entire metal strengthening member.

' It willthus be seen that my device over- 7 comes the inherent weakness of the corr gated cardboard and presents a. deviceof great value and usefulness.

'I'n the accompanying drawings illustratin;modified forms of the device of my inventlon; similar parts are designated by similar-numerals. 7

The particular form of the device of my invention shown in theaccompanying draw- .ingsgcomprises a blank of corrugated cardboardscored and bentalong the lines A-A an d .;B *B,. thus forming the 'front, member 10. and the two triangular side members 11 and 12.

A metal strengthening member 13 of U shaped construction, having the inwardly exn tended staggered teeth 14, 14 is placed around the upright edge of each side member 11 and 12 and the teeth 14, 14 pressed inwardly into the corrugated cardboard of which each side member is composed.

I The two series of teeth 14, 14 in addition to being staggered with respect to each other are offset with respect to each other bymaking' one side of the member 13 slightly longer than the other side. These staggered and off-set positions of the teeth are desirable as they preserve the strength of the corrugated I cardboard, which would otherwise be weakened by the inserted teeth.
