installati-on bracket for Venetian bi'inds.

The second object is to previde'n bracket by means of which the head mail caribe easily and accurately adjusted for heig'htat ends without detractingfnom the appearance of the bracket.

The third object is to provide a bracket of the class described having an outside facia board to prevent the passage of light above the blind, and also to conceal the mechanism of the blind as well as any irregularities in the spacing above the head rail occasioned by adjustment of the blind to provide a perfect adustment of the lower rail with relation to the window sill, such irregularity being due tothe inaccuracies in the window frame itself, or in the construction of the blind, or in the fastening of the supporting tapes, or to changes in the length thereof after manufacture.

The fourth object is to construct the bracket so as to obtain the maximum amount of strength with the minimum amount of expenditure for material and labor for manufacture 4and assembly.

These and other objects are accomplished in the manner set forth in the following specification, as illustrated in the accompanying drawlng, in which:

Fig. 1 is a vertical section taken along the line I-I in Fig. 3.

Fig. 2 is a vertical section taken along the line 2 2 in Fig. 1.

Fig. 3 is a plan showing the head rail and front and rear facia boards broken away.

Fig. 4 is a fragmentary section taken along the line 4 4 in Fig. 1.

Similar numerals refer to throughout the several views.

Referring in detail to the drawing, there is shown the bracket for the left side of the window frame as viewed from the interior. This bracket similar parts consists mainly of a flat plate I D having the inturned vertical edge II Whose lower end I2 is turned horizontally and provided with the upturned tab I3. The outer facia board I4 rests upon the member I2 and against the inner side of the edge II.

Hingedly attached t the plate I0 by means of a rivet I5 is the angle plate I6 whose vertical edge Il is normally parallel with the edge Il.

'lil

The edge IFI-:is tu'med'outwardly along the lower lend 18 to support theinner faciaboard'slll, which is heldV against the edge lii'by the inturned 'tab 12E. i

. A depression 121. made yby acenter 'punch forms 4a convenient latch `for the iapper .end of themember II6 Holes 22l are providedinthe plate 11i as well sasiinnthe edge; II :fori fastening purposes.

Mounted agaiinstrxtheinnerside of the plate {I avertically mnvabledslide 23 which is held in place by the guide 24, preferably spot welded to the plate I0. The upper edge of the guide 24 is out turned to form an ear 25, and has freely passed therethrough the vertical adjusting screw 26 whose head 21 is on the under side of the ear 25. A nut 28 is placed on the screw 26 on the top side of the ear 25, and is prevented from turning by contact with the slide 23.

On the upper end of the slide 23 is secured a channel 3| between Whose lower side 32 and upper side 33 is placed the head rail 34. The upper side 33 is made long enough to serve as a stop for the upper portion of the facia board I4. The upper end 29 of the screw 26 is reduced and extends through the lower channel side 32 and is loosely riveted thereto in order that the screw may turn.

When installing the device, a pair of the plates I0 are installed at opposite sides of the Window frame, and the inner facia board I9 is swung up on the rivets I5, making it possible to easily insert the head rail 34 between the sides 32 and 33 of the channel 3|, and then permit the facia board I9 to drop down and conceal the mechanism.

It is commonly found that when a blind is installed, the lower rail (not shown) either touches the sill or is spaced too far therefrom. With my construction, this dilcultycan be overcome by simply rotating one or both of the screws 26 as the case may be, in order to bring the lower rail into perfect parallelism with the sill of the Window. Once adjusted, it is obvious that no further attention will be required, land that the need for extreme accuracy in measurement of the blind is dispensed with. Moreover, objectionable light leaks at the upper edge of the blind are avoided, and the external appearance of the blind improved by the presence of the outer facia board.

It must be understood that a pair of these devices is required in each installation, and these must be right and left in order to meet the conditions.

It will also be noted that by swinging the front facia board I9 upwardly, the introduction of the head rail into the channel 3l is much simplied.

In some cases, it will be found desirable to hinge the facia board I9 downwardly. To do this, it is merely necessary to reverse the position of the rivets I and the countersinks 2 l.

It is a well known` fact that fastening ears are often applied on the upper ends of the brackets for use when the bracket is to be fastened at the upper portion of the window frame. These have been omitted from the present illustration as they form no part of this invention.

While 1 have thus inustrated and described* my invention, it is not my intention to be limited to the precise form, but I do intend to cover within the appended claims.

I claim:

V- all such forms and modications as fall fairly.

1. An installation bracket for Venetian blinds y consisting of a plate adapted to be secured to a window frame, a shelf mounted on said platefor a vertical plate adapted to be attached against the side of a window frame, a horizontal channel slidably mounted on the inner side of said plate, a slide for guiding said channel, a guide for said slide attached to said plate, a nut supported by said guide, and an adjusting screw extending upwardly through said nut to said channel whereby the rotation of said screw will change the elevation of said channel, said channel consisting of a support forone end of a head rail of a Venetian blind.

4. An installation bracket having in combination a vertical frame engaging plate adapted to vbe secured to a window frame normal to the window glass, the outer edge of said plate being inturned, an outer facia board disposed against said inturned edge, a vertically adjustable channel mounted along the inner upper side of said plate, the upper portion of said channel engaging said outer facia board, an angle plate hinged at its upper end tothe interior edge of said rst mentioned plate, said angle plate also having an inturned edge, an inner facia board engaging said last mentioned inturned edge, means for holding said inner facia board in position whereby said inner facia board may be swung upwardly in a manner to give access to the innermost end of said channel` for the purpose of inserting a Venetian blind head rail therein. f
