VZEfiETl'A'N-BLIND TILTING-RAIL FIXTURE.

Application filed April 12, 1926. Serial 110. 101,360.

This invention relates to means for maintaining Venetian blinds in appropriate adjustment and is especially applicable to those blinds having a pivoted header bar from which the blind slats are suspended by suitable flexible connections.

The invention more particularly relates to a bracket and gouging combination at one end of the header, and an object is to provide a simple arrangement of this kind that can be easily adjusted to a desired working condition that is to say, to allow the header bar to turn with a certain degree of resistance and a certain degree of freedom.

Cheapness and simplicity of construction are features of the invention, and in this respect I have provided a bracket formed of a single piece of sheet metal bent at the top to form an attaching flange and also bent to form downwardly extending side members for the purpose of forming a pulley hanger, and the out-er side member being provided with a strip bent parallel thereto to form a double bearing for a gudgeon that supports one end of the pivoted header bar or blind header, and also to form ahousing for a block which may be clasped between the housing members to regulate the friction with which the block can be turned; said block being non-rotatably fixed relative to the gudgeon and the gudgeon non-rotatably fixed relative to the pivoted header bar so that when the header bar turns the gudgeon will turn and will thereby turn the block, the friction of which against its support determines the ease with which the blind header can be adjusted by pulling on the usual cord.

. Other objects, advantages and features of invention may appear from the acompanying drawing, the subjoined detail description and the appended claims.

The accompanying drawing illustrates the invention.

Figure 1 is an edge View, partly in section, of a Venetian blind header bar and supporting bracket embodying my fixture.

Fig. 2 is a bottom view of the same with the slats and supporting webs removed.

Fig. 3 is an end view of the same looking from the left of Fig. 1.

Fig. 4 is a detail side viewof my novel bracket looking from the right of Figs. 1 an 2.

Fig. 5 is an end view looking from the right of Fig. 1 illustrating the end fixture opposite the bracket.

Fig. 6 is a detail View of the resilient triotion member.

Fig. 7 is a detail view of the block that is supported in the bracket.

Fig. 8 is an enlarged fragmentary plan view of my devicegparts being in section to illustrate the construction thereof and the header bar being tilted for purpose of more clearly illustrating the tilting operating cords.

, A mounting block 1 of well known and standard construction has a header 2 mounted thereon by means of a bracket 3 and a fixture 4 secured thereto. A plurality of blind slats, a of standard and well known construction are suspended from the header 2 by suitable flexible connections or webs b. The cords 5 trained over pulleys 0 are used to draw the slats into compact arrangement.

The header'Q is providedat one end there-. of with a gudgeon 6 which is journalled in a bayonet joint 7 in the fixture 4. The fixture 3 in which the other end of the header 2 is mounted is preferably formed of a single piece of metal bent at its top to form an attaching flange 8, through which suitable screws or nails etc., extend into the mounting block 1, thus securing the fixture in place.

An outer side member 9 is bent downwardly at right angles to the flange 8, and is provided with a strip 10 bent parallel to the outer side member 9 in spaced relation thereto to form a double bearing for the gudgeon 14.

An inner side member or ear 11 extends forwardly of the fixture proper and is bent from the flange 8, parallel to the side member-9, for the purpose of forming a hanger for a roller 12 which is positioned between V the side members 9 and 11 and is journalled on a pin d extending therethrough. A header bar tilting rope 13 extends over roller 12 and is wrapped around the header 2 in the manner shown in Figs. 3 and 8 and is secured thereto by a screw or pin 6.

The gudgeon 14 is preferably squared and extends through the squared hole 15 in block 16 thus non-rotatably securing such block relative to the gudgeon and header bar. The block 16 is positioned between the side member 9 and strip 10 and is journalled in said member 9 by an annular ring 17 extending from the block 16.

A. yieldable friction member such as the washer 18 bears against the block 16 and strip 10. The gudgeon 14 extends through the washer 18 and projects through a hole 19 in the strip 10.

A screw 20 extending through member 9' is threaded into the strip 10 adjacent the free end thereof. Thus it will be seen that by adjusting the screw 20, the strip 10 may be moved into closer relation with the member 9 and the tension of the spring washer 18 against the block 16 may thus be increased, to thereby permit said block to rotate with more or less freedom as desired.

As the header 2 is non-rotatably secured to the block 15, the swinging movement of the header is governed by the frictional resistance to said block and which resistance may be easily and quickly adjusted by adjusting the screw 20. By obtaining the proper frictional resistance, the header 2 and the blind slats depending therefrom, will re main in any adjusted tilted position obtained by pulling on cord 13.

The strip 10 has sufiicient outward spring therein to urge it away from the member 9, thus holding the screw 20 in its seat in said member.

I claim.

1. A Venetian blind comprising a header; a bracket in which said header is pivotally mounted, said bracket comprising an integrally formed side member and a strip spaced therefrom; an attaching flange angularly positioned to said side member; an ear bent from said flange to form with said side member, a hanger; a pulley mounted in said hanger; a block positioned between said member and strip; a gudgeon extending from said header and being non-rotatably mounted in said block; and means to ap ply frictional resistance to said block.

2. An article of manufacture comprising a bracket formed of a single piece of sheet Leeazse metal bent to form an attaching flange and also bent to form a downwardly extending side member; a strip bent parallel to and spaced from said member; an ear bent from said attaching flange and spaced from said side member to form therewith a pulley hanger; a block positioned between said strip and member; and a screw mounted in said strip and member to vary the spaced distance of said strip and side member.

3. An article of manufacture comprising a bracket formed of a single piece of sheet metal bent to form an attaching flange and also bent to form a downwardly extending side member; a strip bent parallel to and spaced from said member; an ear bent from said attaching flange and spaced from said side member to form therewith a pulley hanger; a block positioned between said strip and member; a screw mounted 1n said strip and member to vary the spaced distance of said strip and side member; and a yieldable washer positioned between said block and strip.

4:. A combination with a Venetian blind header bar having a gudgeon fixed thereto; of a header bar support comprising a bracket formed of a single piece of metal bent to provide an attaching flange; and an outer side member bent downwardly at right angles to said flange; a strip integral with and spaced from said side member; an ear formed on said flange and extending parallel to and forwardly of said outer side member; a a block disposed between said strip and side member; said gudgeon being non-rotatably mounted in said block; a washer disposed between said block and outer side member for regulating the frictional resistance of said block and a roller having bearings in said ear and outer side member and being disposed forwardly of said side member.

In testimony whereof, I have hereunto set my hand at South Pasadena, California, this 3rd day of April, 1926.
