- 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

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.
It “will be noted that the means D for main

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

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

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 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

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
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

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.
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.

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

be used to conceal these 'parts.
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

releasably holding said head rail in tilted posi

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

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-'
