L, assignor to Artcraft Venetian Blind Company, Hazleton,

Application September Iii, 1934, Serial No. 744,571 2 Claims.- (Cl. 156-17) Thisinvention relates to improvements in Venetian blinds, the general object of the invention being to provide a casing enclosing the pulley bar and the parts carried thereby as well as the upper part of said blind, and means for detachably connecting the casing with the top of the window frame.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the. several views, and in which:

Figure l is a transverse sectional view through the casing and the top rail showing the means for tilting the top rail.

Figure 2 is a fragmentary front view of the cas ing with parts broken away and showing how the casing is supported at the upper portion of the window frame.

Figure 3 is a view showing the end of the casing and a supporting bracket with the latch for locking the casing to the bracket.

Figure 4 is a view of the stationary bracket which holds one end of the casing to the window frame.

Figure 5 is a view of the latch means for locking the casing to a bracket.

In the drawing the window frame is shown at A and B indicates the casing adapted to be supported in the upper end of the frame, said casing having its top part formed by the pulley bar I of the blind, the end pieces 2 which are fastened to the ends of the bar I and the metal or other suitable part 3 which is fastened to the bar I and the ends 2v and forms a front and bottom of the easing, the rear of the casing being'open. The bar I is provided with the usual groove I. A pair of brackets support the casing in the top of the window, each bracket 4 being fastened in an upper corner of the window frame and each bracket includes a flange 5 horizontally arranged at its top andformed with a notch 6. A plate I is attached to each end of the bar I and has its outer partoffset as shown at 'I' so that the flan e 5 of the bracket 4 will pass under the offset part and over the upper edge of an end piece 2 of the easing, when the casing is moved into the window frame, so that the brackets 4 will support the casing at the top of the window frame. A latch 8, see Figure 5, is pivoted to the outer face of the end member 2, as shown at 8' and has a projection 9 on its upper edge for entering the notch Ii when swung upwardly so that the latch locks the casing to the bracket.

The top rail is shown at I0 and is supported for tilting movement in the casing in any suitable manner, the supporting means including the brackets I2 and I5 and said rail is tilted through means of the chain I8 passing through holes in a portion of the, casing and over a pulley Il connected with a worm shaft IS, the worm of which meshes with a worm gear I4 which is supported from the rail.

As will be seen thecasing is detachably supported in the top of the frame whereby the blind structure can beeasily put'in place or removed, with the casing hiding from view the upper portion of the blind.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction-and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

What is claimed is:

1. In a Venetian blind, a casing for receiving the upper-portion of the blind, a bracket adapted to be connected to the upper portion of a window frame, the bracket having a horizontal flange provided with a keeper recess, a member connected to the top part of the casing at an end thereof and having a portion spaced from the casing, the space receiving the horizontal flange of the bracket and a latch member pivoted' to the end of the casing and having a part for engaging in the keeper recess of the bracket when the latch mem her is in operative position.

2. In a Venetian blind, a casing having its top part formed by the pulley bar'of the blind, said casing including end members depending from the ends of the bar, and a member attached to the bar and end members and forming front and bottom walls of the casin a plate connected to an end of the bar on the upper face thereof and having its outer portion offset upwardly, a bracket adapted to be fastened to the top part of a window frame and having a horizontal flange for fitting in the space between the offset part of the plate and the end of the casing, the flange having a keeper recess therein and a latch member pivoted to an end piece of the casing and having a projection for engaging in the keeper recess when said latch member is in raised position.
