(lUl. 156-17) tilted position, and a- means E for raising and - This invention relates to and has for an ob ject thereof the provision of a novel form of Venetian blind which comprises fewer parts than used in the present day types of such blinds, g, and entails less cost in production and installa tion thereof while aifording all of the desirable appearances,e?ects and features of said pres ent day types. , ’ An additional object is to provide a Venetian lowering the foot rail and said slats. As here shown, the Venetian blind elements and the operating means therefor are installable and'removablei as a unit through use of-the 5 means B which comprises channelled end mem bers t and 9 which slidably receive and fric tionally hold the head rail 3 at the ends of the latter. The end member 8 is provided with‘ an 1o blind of the character described wherein there _ opening it for reception of a trunnion ll car- 10 is conveniently provided between an end of the ried by the bracket l. [The end member 9 is pro tiltable head rail and a rail supporting bracket, vided with a headed trunnion‘ l2 adapted. to be removably received in an upwardly opening an efficient yet simple means for releasably hold socket it formed in the bracket 2. It will now ing the head rail against unintentional move it ment from a predetermined tilted position. be seen that with the brackets installed on the 15 Other objects may appear as the description window frame or the like, the head rail having progresses. I have shown a preferred form of my invention in the accompanying drawings, subject to modi 20 ?cation within the scope of the, appended claims without departing from the spirit of my inven _In said drawings: .

This cord is extended 25 over the top of the head rail and depends from opposite ‘sides thereof with its ends in position at all times to be grasped and pulled whereby to rock said head rail in either direction and ac- _ cordingly tilt the slats, as desired. 30 It “will be noted that the means D for main taining the head rail against unintentional move ment out of a predetermined tilted position in cludes a circular series of depressions it formed in the bracket 2 concentrically with the axis of 35 the head rail. Cooperating with these depres sions is a spring urged detent means comprising spring arms I‘! ?xed to the‘end piece 9 by the trunnion l2 and extending laterally in opposite directions therefrom with their outer ends clear' 40 Fig. 9 is a sectional view taken on the plane - of. said end piece. On these outer ends are rounded detents l8 adapted to be engaged in' the of 'line 9—9 of Fig. 3. ‘ ' One embodiment of the Venetian blind‘ of this depressions l6 as the head rail is tilted. Thus, invention comprises brackets L and 2 adapted 45' to be secured to a window frame’ A or the like, a head rail 3, a means B for tiltably and remov vably supporting said head rail in said brackets, a foot rail 4, pairs of ?exible hangers 5 depending from said head rail and secured to said foot rail, 50 ‘slats 6, ?exible straps ‘I carried by said hangers and supporting said slats for’ tilting movement and for the raising and lowering thereof, a means C for‘ tilting said head rail and slats, a means D for releasably holding the head rail against 55 unintentional movement out of a predetermined it is seen that in all positions into which the head rail is turned or tilted, the detent means D will 45 operate to maintain the desired tilted position of said rail and the slats 6. ’ In accordance with this invention I employ the single rail 3 to take the place of the separate head rail and tilt rail employed in the present 50 day types of Venetian blinds. In using one rail to serve the purpose of the two rails, I‘eliminate the use of‘comparatively complicated and~_ex pensive hardware, it only being necessary to em ploy a simple form of bracket to install the blind. 55 I 2 2,187,444 Furthermore, the means for tilting the slats and by and between said rails, means carried entirely the means for raising and lowering the blind are by said head rail for tilting said head rail, said of a simple and inexpensive form by reason of ’ means for tilting said head rail including an up standing lug on said head rail and a ?exible op the use of a single header bar in accordance with this invention, it being noted that the said oper ating means are solely supported by the single bar. I In accordance with this invention the means E, for raising and lowering the blind, comprises 10 a ?exible operating element or cord l9 having its ends secured to the foot rail 4 and extended upwardly through apertures in the slats 6, then through openings 20 in the head rail and around pulleys 2|. The cord I9 is then doubled and 15 extended over an end pulley 22 and allowed to hang from the head rail so that it may be read ily grasped to raise and lower the blind. On the window frame A is a cleat 23 to which the cord I9 is secured to maintain the shade in pre ends to said trunnion and having its free ends outwardly o?set, and a similarly outwardly olf set portion on said bracket on opposite sides of .said slot for frictional contact with said ends of said spring member. 2. In a Venetian blind, brackets therefor, a head rail, channelled end pieces on the head rail, means for tiltably mounting said end pieces on said brackets, Venetian blind elements support~ determined elevated ‘positions. ed solely by said head rail, means supported - It will be noted that the rail 3 is recessed or grooved on its upper side for reception of the pulleys and cord, and that a cover plate 24 may solely by said head rail for tilting said head rail, be used to conceal these 'parts. Furthermore, the end pieces 8 and 9 may be secured in place, if desired, by fastenings 25. ' It will now be seen that the Venetian blind of this invention will provide for the advantages ‘hereinbefore noted in a particularly efficacious 30 erating element secured to and depending from 5 opposite sides of said head rail, and means for releasably holding said head rail in tilted posi tion including a'headed trunnion on said head rail, one of said brackets having a slot receiving said trunnion, a spring member ?xed between its mannert What I claim, is: 1. In a Venetian blind, brackets therefor, a head rail tiltably supported by said brackets, a foot rail, a Venetian blind structure supported including a headed trunnion on- one of said end pieces, one of said brackets having an upwardly opening socket therein removably receiving said headed trunnion, a spring member ?xed between - - its ends to said last named end piece, said last named bracket having depressions therein and .detent members on the ends of said spring mem ber and adapted to engage in said sockets, said means for tilting said rail including an upstand- 1 ing lug on said last named end piece and ?exible operating members secured to said lug and de-' pending from opposite sides of said rail.
