It will also be seen that the vertical bars of the frame may be provided with an offset inwardly as at C in which the side peripheral edges of the screen will seat as means to prevent inward deflection of said screen.

Positioned inwardly of the screen and being carried by the vertical side bars of the frame 55 are a plurality of horizontally positioned slats I2 spaced apart vertically, the ends of the slats, each having a ball l3 formed thereon to rockably and slidably engage in grooves 14 that are positioned in the confronting sides of the vertical bars substantially their entire length, said grooves having a diameter equal to that of the ball to retain the same therein for permitting sliding and rocking movement of the neck [5 as carrying means for its respective ball.

To rock the slats is through the medium of a chain [6, said chain being carried and engaging over a flanged roller I! that is rotatable on a horizontal shaft [8 which has its ends rigidly secured in the vertical bars of the rectangular frame at their upper extremities. The chain depends downwardly from the roller, the lower ends of said chain being secured to oppositely disposed edges of a lowermost slat I!) which is similar as slats l2 but being increased in thickness to avoiddeflection when the slats are raised upwardly as later described. It will be seen .that the slats have their respective side edges secured to the chain in equal spaced relation ther'ealong, whereby when the chain is gripped by an operator, the slats may be rocked to a desired slant, and also the slats may be rocked by gripping a slat to rotate the same on its longitudinal axis, which in turn will rock the other slats, correspondingly. The side edge of each slat is secured to its associated link of the chain by a pair of cars 20 intcgrally joined to said slat, and between which the link will engage, and through which a pin 2i extends :as securing means for the chain to said slats.

The slats may be raised upwardly in stacked relation, if so desired, by pulling downwardly the free end portion of a pair of cables 22, said cables engaging over their respective flanged rollers 23 that are journalled on shaft IS, the fixed portion of the cables running through the slats and being fixed at their lower extremities to the lower slat l9 by any suitable means such as by an eye D as shown in Fig. 4. By pulling the free end of the cables downwardly, the lower slat will move upwardly to contact its adjacent slat, which in turn engages its next succeeding slat, and so on, until all slats are contactingly engaged and positioned rearwardly of the plate 8 as obscuring means for the slats from an external view. To retain the slats, upwardly positioned, is by forcing the free end of the cables into their respective hooks 24 that are secured adjacent the lower end of the vertical bars, said hooks having their members diverging outwardly to permit wedging of the cables when forced inwardly therebetween. It will be understood, however, such method of fastening the free end of the cables may be varied as preferred by the manufacturer.

As a means to partially obscure the rollers and 50 the shaft from view internally of a room, there is provided a member, angle-like in cross section, one leg, as at 25, depending downwardly to enclose the rollers, while leg, as at 26, of the angle is secured to the inner side of the upper bar of the rectangular frame by screws 21 as shown in Fig. 4.

To look the slats, against opening from a closed position and as positioned in overlapping relationship, is through themedium of one or more leaves 28, which are hingedly connected to the inner peripheral edge of the vertical bars, said leaves being adapted to rock inwardly to engage on the slats and retain the same closed against force that may be applied externally on said unit.

While the invention illustrates the free manipulating ends of the cables externally applied of the window, the same may be run through the building, if so desired, without departing from the spirit of this invention, and furthermore while the invention otherwise is shown and described specifically, the details such as to the exact type of material, proportion, and arrangement of components thereof may be varied as lie within the scope of the appended claim.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

In a combined screen and Venetian blind unit for window frames comprising a rectangular,

frame consisting of vertical bars, and horizontal bars at the upper and lower ends of said vertical bars, a screen to partially enclose the frame, a plate to enclose the remaining portion not enclosed by the screen, said plate being secured adjacent the upper extremity of the frame, a plurality of horizontally positioned slats, means in the vertical bars to rockably and slidably carry the ends of said slats, means for rocking the slats about their longitudinal axis, means to raise the slats upwardly in stacked relation to position the same rearwardly of said plate for obscuring the slats from an external view, and means to lock the slats when the same are suspended and slantingly rocked to overlapping relationship.
