BLIND For; WINDOWS Frank C. Ribley, North Troy,"N. Y. Application September 23, 1946,.Serial No. 698,653

1 Claim. (01. 160-107) This invention relates to, a new and improved window blind and rain proof ventilator' which has as its primary object the provision of an arrangement comprising a screen and metallic slats positioned within a window frame, outside of a window, to regulate the light entering ayvindow and which will form, when desired, a rainproof shutter which allows free ventilation through the window.

Another object of this invention isf the provision of a device of the character described which is quickly and easily operable into several positions and which is easily applied to a conventional window. structure. 7 j

Still-@nother object of this invention is the provision of a device of the character described which'is of durable yet simple and -inexpensive design and a device which has the'viminimum of working; parts which might, with use, become worn and broken.

Still-further advantages and improvements of this invention will readily appear to -those skilled in the, art when the following descriptionis read in the'j light of the accompanyingdrawings in which:

Fig. 1 is a front elevation of the blind.

Fig. 2 is a vertical section taken on line 2-2.

Fig. 3 is a horizontal section taken on line 33.

Fig. 4-is a vertical section taken' on line 4-4.

Fig. .-is a vertical section taken o n line 5-5.

Fig. 63 is a vertical section takenon line 6-6.

Referring now to the drawings ;in which like numerals indicate similar parts} throughout A designates a window frame housing the conventional sashes I and 2 of the window.

A second frame 3 adapted to be securely fitted the frame A from the ou Qde of the winshaft- ,8 mounted in said bea r gs is a slatted.

blind *9 comprising a plurality, .thorizontal slats l0 rotatably mounted on shafts ll identical to the shaft 8 which corresponds to the shaft ll of thefupper most slat. The outside longitudinal edgetqf each of these slats was curved upward as atflZ and secured as at 13 to two tapes ll and I5 which interconnect the upper most and lower most slats on their outside edges, while two similar tapes l6 and I1 interconnect the upper most and lower most slats on the inside but these tapes are not secured to the intermediate slats as are tapes [4 and I5.

A blind cord B is secured as at I8 to one end of the shaft ll of the lower most slat and then passed upward over the upper pulley wheel 5 and then looped downward under the pulley wheel 5 at the lowerocorner, then horizontally around the wheel 6 and back around the lower wheel 5 and upward to the shaft II where the opposite end of the cord is secured adjacent the first end at l9.

This cord arrangement is effected on both sides of the frame, so that a turning of the wheel 6 will cause the end ill to be pulled upward over the upper pulley wheel simultaneously allowing the needed amount of slack to accumulate at 19 to allow the opposite end to play upward with the first end.

This arrangement allows the blind to be raised or lowered.

The tilting of the blind is accomplished by a hand lever 20 which is rotatably secured at its upper end, as at 2|, to a crank arm 22 which is afiixed to the end of shaft 8, or II, of the upper most slat.

By moving said lever arm upward crank 22 rotates shaft 8, or II, so that the outside edge 23 ,of the slats I0 is tilted downward to approach the upper curved end l2 of the slat I 0 below it.

This provides that the slats may be moved to form a solid enclosure as shown in Fig. 6 or they may be positioned in any intermediate closing state.

The lower end 24 ofthe lever arm 20 is adapted by a, hooked end 25 to engage one of a plurality of detents 26 spaced vertically in a plate 21 secured to the bottom corner of the frame 3.

This arrangement provides for the securing of the slats in their desiredrtilted position.

I Having thus described the structure and operation of this invention, what I claim is:

A combination screen and slatted blind for wining therewith; tapes connecting said slats; a plurality of intermediate slats spaced over the distance between said first-named slats and connected to the tapes; 2. pair of upper and a pair of lower pulleys rotatably mounted at the upper and lower corners of the screen frame respectively; an operating pulley rotatably mounted at the lower end of the screen frame and disposed midway between the" lower corner pulleys; and a pair of blind cords, each cord being-secured at one end to one end of the lower shaft and bein trained ardly from said lower shaft along a, side of the screen frame over one of the upper.

corner pulleys and extending downwardly from said upper corner pulley around one of the lower corner pulleys and being wound upon the o'purafit ing pulley.
