Application filed February a, 1926. serial no. sense.

This invention relates to im rovements in mountings for Venetian blmds whereby to be opened to 'any desired extent without when such blinds are used adjacent windows having the fenestra sash, or .one in which one or more sections swing u on horizontal axes, the Venetian blind may e readil adjusted to different positions away from t e w ndow to permit the movable section of the window in any way interfering with the blind or with its usual mode of operation.

One object of the present invention is to provide Venetian blinds with animproved mechanism for movably supporting the blinds to enable the'same to be readily and conveniently adjusted to accommodate windows of the above mentioned t pe.

Another object of the invention is to provide such a structure wherein the Venetian blind may be operated in theusual manner in so far as'adjustment of the blind itself is concerned, while at the same time providing a most convenient and efiicient arrangement for moving the blind to its various positions and maintaining the blind in a vertical position whatever may be its relative position in respect of the window with which -,it is used.

blind in its osition closest to the window;

Figure 11 is an end elevation of theparts 7 shown in Figure 10; and

Figure '12 is a side elevation ofthe upper portion of the blind and supporting bracket.

Referring to the drawings and particularly to Figures 1, 3 and 4, the Venetian consists of the to number of slats 2 which are allconnected together and to tl1e 'top or tilting bar 1 by tapes 3 which are secured to one side of the bar 1 and to the edges of all of the slats, as is usual in Venetian blind construction. In order that the objects of the invention may be accomplished the Venetian blind is su ported solely at its top wherebyit 111a iie moved to various positions toward and i i'om the window adjacent to which it is hungand at the same time maintain its vertical position and be 0 erable inthe ordinary .way for raising an lowering the blind and changing t e angle of the slats'as desired.

In the preferred form of the invention this mounting of the blind and its adjustabilitv toward and from the Window is acbar 4 mounted above the tilting bar 1 and pivotally connected thereto. This connection is preferably effected by means of an angle iron 5' engaging the under side of the right-hand end of the sup ortin bar 4 and an angle iron 6 engaging t e un er side of the left hand end thereof.

each angle iron, so; that said bar may rock upon said pmtles and thereby change the angular position of its slats 2. The means shown in Figure '1, the ends of the cord be- 1 ing connected to thetop and bottom respectively of the bar 1, whereby pulling the outer strand of the cord -7 causes the slats to be rocked in one direction, while the opposite Pintles, extending irom the bar 1, enter holes, one m bar 1 and a Ill" direction of movement is effected by pulling a the otherstrand of readily understood.

Theadjustment of the Venetian blind toward 'and from the window is preferably the cord, as will be side of the blind, which arms pivotally support the bar 4 at upper ends of the arms, rackets 11 being provided for this purpose, and also pivotally engage brackets 12 at their lower ends, Figure 1. By this arrangement it will beunderstood that as the arms 10 are moved outwardly the Venetian blind also moves outwardly but always maintains its vertical position, being freely suspended from its top ortion only. When the blind is closest to t e window as in Figure 4, the arms 10 are not quite vertical but are slightly inclined away from the window so that the weight of the blind is enough to cause further movement away from the window when such movement is permitted b the means which normally restrain the lind flrom movement and which meanswill now be described.

Preferably there is provided a chain or cord, thetwo portions of which 13 and 14 are connected to the bar l. the portion 13 near the left-hand end and the portion 1d near the right-hand end of said bar. The portion 13 passes through a sheave 15 of a bracket 16 and over a roller 17 in a bracket 18. This latter bracket also carries a roller 19 situated in a difierent vertical plane from the roller 18, as shown clearly in Figure 6, and the end 14 of the cord after passing over a sheave 20 carried by a bracket 21 passes over said roller 19 below which said two ends of the cord are united in a loop. The loop is formed by a ring 22 secured to the two strands of the cord, such ring forming a stop to limit the'movement of the blind away from the window. Preferably the bracket 18 has a recess or depression 23 in its underside with which the ring 22 engages. The cord 24 is secured to the loop and is manipulated manually to adjust the blind toward and from the window.

It is desired to avoid noise and jar when the blind is brought up adjacent the window and to accomplish this I have provided cushioning means in the form of bumpers 25 and 26 secured to the bark and so positioned that they will contact respectively with abutments 27 depending from the brackets 16 and 21.

The Venetian blind itself is moved up and down to shorten or lengthen the blind by the usual cords 28 which are secured to the bottom slat and which pass about guide rollers on the bar 4 and depend for convenient mani ulation at the right side of the blind as siown at 29. The window frame is shown somewhat diagrammatically, the top portion thereof being indicated at 30 and the swinging sash portion at 31 pivoted on a horizontal axis 32 whereby it may swing, as shown in Figure 3.

With the construction described avery convenient and efiicient means liasgbeen provided whereby the blind may be adjusted to different positions parallel with the window to accommodate it of the degree of opening to the swinging portion 31 of the window and-at the same time provide for manipulation of the blind in the usual way, in any osition.

In Fi \res to 12, I have shown a slightlv modified construction and one which differs from that just described principally in the fact that instead of providing the swinging arms 10 there is provided a bracket 33 and a bracket 34, one at each side of the blind, and secured in any suitable manner adjacent to the window frame. One of these brackets 33 is shown in enlarged elevation in Figure 12, wherein it will beseen that the same is rovided with a slotfor supporting and ad usting the blind in its various positions. As in the first described construction, the top bar 35 of the Venetian blind is pivotally connected in the same manner as already described, to the second bar 36, but the manner'in which this second bar 36 is mounted for adjustment is different. At each end this bar is provided with an angle piece 37 secured by screws 38 to the bar 36. A stud 39 is screw-threaded or otherwise secured in one arm of the angle member and is provided preferably with a hexagonal portion 40 -forming an abutment to en age the angle member, whereby it may e securely screwed to said member. A flanlgedroller 41 is mounted on the stud and is held in place by means of a screw 42, said screw enga ing internal threads in the head of the stud. As shown inFigure 12, the bracket 33 is provided with a slot 43 which is enlarged at its right end 44, the enlargement being of such size that the roller 41 may lie/inserted therethrough so that the flanges of the roller may then ongage on opposite sides of the track portion of the bracket, after which the screw 42 is inserted. The cord connections, whereby the blind is adjusted toward and from the window, and whereby the blind is moved to lengthen or shorten the same, and to change the an ular position of its slats, are the same as in t e first described form.

. It is to be understood that variations may be resorted to within the spirit of the invention as described, without departing from the spirit thereof. i
