This. invention relatesv to.y improvementa in had bQX. CQDSTUQQB for Yentan. bhni all@ maunting bracket therefQl- The, principal-l orreztfs.` of, this inventiqnr are;

First, te provide a, noi/,elf ferm. 0fv head. box construction for supporting Venetian blindsincluding theA lifting and tiltinggmechanisrn for the slats ofthe blind which will permit'`A a givenr set ofparts to be adjusted to. .t different, widths. of Windows.

Second, to, provide a mounting bracket for the head boxy of a Venetianblind which canbeI used aseither arightor leflbracketon the headbox and which can be adjusted for attachment4V to either the front, inside, or the underside of the lintel of a window frame.

Third, to provide a head box including a facia piece for a Venetian blind in which the facia piece can be manufactured and shipped in iiat condition and bent around the ends of the head boxA on installation or left flat for longitudinally extended head boxes.

Fourth, to provide head box construction for a,V Venetian blind in which two. body members supporting tilting mechanism and lifting mechanism are adjustably connected by a rail member todetermine the distance between the body membersrand thereby determine the length of Venetianblind which the head b ox will support.

Fifth, to reduce the cost of Venetian blind con-v struction by providing standard elements or subsections for a headY box which can be adjustably assembled with different rail members for determining the length of the Venetiany blind.

Other objects and advantages pertaining to details and economies of my head box construction will be apparent froma considerationA of thek following description and claims.

The drawings, of which there are two sheets, illustrate a preferredform of my head box conn struction.

Fig. 8 is a planview ofthe bracket shown/ in Fig. 1.

My head boxconsists'ofaleft bodymember I and right body member 2-joined togetherin the back by a rail member 3 and enclosed in the frontby a facia pieceA. The space between `the body members and,l behind the facia l` may be closed by a center dividing,A plate 5 as shown in Figs. 2, 3, 5, and 6. The body members I andn 2 serve to support the well known ladder tapes 6 and slats 'I in a manner` to be. describedpres: ently.

The left body member I isvofupwardly opening channel shaped crosssection andis conveniently formed as a stampingd provided'. witljr am front flange 8 and rear flange951.lpirreclgby, theweb, I0; The body member luisn provided' with a trans-v verse partition plate` II and' va pulley supporting bracket l2-Y The. partiten. plate I'Ilservesasa. supporting bearing forvtlieT tilt. shaft I'3 .lraving the gear segment I Ajmounted thereonvandvthe bracket I2 supportsrthe pulley shaft I 55j andpulley drum I6 arranged to berotatedby the tiltjcords II.` The tilt shaftv I3l is connected to an ex.- tension shaft I8, by means of asegrnentaltape hub I9` which serves. te supporttheleftladder tape 6.

The right body member 2 is: also of; upwardly opening channel shaped's'crossA section and*A is formed `'as astampingfhaving a rear l ange 2D and front iangell joined^gby7the ,web 22. The body member 2iis providedgwitha shaft -support ing arm 23 k(see Figs.,3f and 46) arrangedtoref ceive the right end o'fjthe extension shaft 'I8;and is further provided gwith aliftv cord lock bracket 24 for locking: the liftcordsin any; of* their adjusted positions.A Thveright-end ofl the extension shaft I 8 carries a segmental lift1 cord hub I9, thesame as the .hubat theleft end of the extension shaft I8 for supportingthe right ladderV tape E.

The

forward anges

8 and 2| of the two body members are each provided with ears 30 which are pressed forwardly from the lower portions of the flanges and turned downwardly as is most clearly shown in Figs. 2 and 4 to engage the rearwardly turned flange 3l on the bottom of the facia 4. The upper edge of the facia is provided with a rearwardly turned flange 32 which receives the locking screws 33 behind the front anges of the body members. The

front anges

8 and 2| are further provided with triangle shaped rearwardly inclined lugs 34 which engage the screws 33 for holding the facia piece on the body members. As will be noted in Figs. and 6,

the flanges on the fac-ia 4 are notched near they ends as at 35 so that the facia may be either bent rearwardly around the ends of the head box as indicated by the dotted lines at 36 or left straight to overhang the ends of the body members as shown in full lines at 31.

The outer ends of the web portion of the body members I and 2 define a pair of taped apertures 53 arranged to receive the mounting screws 39 for securing the head box to the mounting brackets 40. The mounting brackets are identical and reversible so that they will fit both the right and left body members. The brackets consist of angle shaped clips 4I defining apertures 42 in each flange thereof for attachment to a window casing. One flange of the brackets d!! is pivotally connected by a rivet 43 to the angle shaped arm 44, the free branch of which denes a slot 45 through which the screws 39 extend for attachment to the webs of the body members I and 2.

By rotating the angle arms 44 on the brackets M, the brackets 4I may be brought into any desired relationship with the window casing to which they are to be attached. Figs. 5 and 7 show a bracket arranged for supporting the left end of a head box either from the front surface of the window casing or from the inside surfaces of the window casing. Figs. 3 and 6 and the dotted lines in Fig. 7 show the bracket member 4I turned to support the end of the head box l from the bottom of the cross piece or lintel of the window casing. The slots i5 permit longitudinal adjustment of the body members I and 2 relative to the brackets 40 thus providing a further longitudinal adjustment of the position of the head box on the Window casing relative to the points of attachment of the brackets 130.

From the foregoing description it should be apparent that the body members I and 2 and the operating mechanism supported thereby is standard for any width of window. All that is necessary to adapt the body members to any window is to provide the proper length of extension shaft I8, rear rail 3, partition plate 5, and facia 4. The body members are further longitudinally adjustable on the rear rail so that the rails themselves can be standardized in a few convenient lengths and made to fit practically any width of window. The facia piece is also adjustable for length by either bending back the ends as at 36 in Fig. 5 or leaving them straight as illustrated in the full lines.

I have thus described a highly practical commercial embodiment of my head box construction so that others may reproduce the same with such modifications as may be desirable without further description on my part.

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