WALLACE B. HUGHES, OF DALLAS, TEXAS. .
VENETIAN BLIND OR SHADE.No. 857,066.
To all whom it may concern:
Be it known that I, WALLACE B. HUGHES,
a citizen of the United States, residing at
Dallas, in the county of Dallas and State of
5 Texas, have invented certain new and useful
Improvements in Venetian Blinds or Shades,
of which the following is a specification, ref-
erence being had therein to the accompany-.
ing drawing..
10 This invention relates to improvements in
an inside blind or shade for a window, and
particularly to that class commonly known
as "Venetian" blinds or shades.
The object of the invention is the provision
15 of means for facilitating the closing of the
slats.
Another object of the invention is the pro-
vision of means for facilitating the raising of
the blind or shade.
20 With these. and other objects in view, the
invention consists of certain novel construc-
tions, combinations, and arrangements of
parts, as will be hereinafter fully described
and claimed.
25 In the drawings: Figure 1 is an elevated,
front view of a blind or shade constructed in
accordance with the present invention. Fig.
2 is a view taken on line 2, 2, Fig. 1, looking
in the direction of the arrow, of the worm-
30 gear device, which is secured to the primary
member or roller. Fig. 3 is a view taken on
line 3, 3, Fig. 1, looking in the direction of the
arrow, of the worm-gear device for actuating
the auxiliary member or roller. Fig. 4 is a
35 view in elevation, of an embodiment of the
invention, in which the sections of the pri-
mary roller are connected by integral por-
tions. Fig. 5 is a view of another embodi-
ment of the invention, in which the sections
4o are connected by, preferably, a metallic
strip. Fig. 6 is a transverse, sectional view
taken on line 6, 6, Fig. 5, looking in the direc-
tion of the arrow. Fig. 7 is a detail view of
one of the gear-wheels and a portion of the
45 sprocket-chain employed in lifting the blinds.
The generic structure of my invention in-
volves the positioning of an auxiliary, rota-
table roller within a primary member, prefer-
ably a roller. The primary member or roller
50 is capable of rotary movement, and for actu-
ating these members or rollers, I preferably
employ independent worm-gear devices.
The slats are opened and closed by the pri-
mary member or outer roller, while the inner
55 or auxiliary roller raises or permits the blind
to be lowered.Patented June 18, 1907.
For a more complete understanding of the
different embodiments of my invention, ref-
erence may be had to the accompanying
drawings, in which 1 designates the frame of 6o
the window, constituting a support. Brack-
ets 2,.Fig. 3, are secured to the inside of the
frame near its upper end, and supported upon
these brackets is an auxiliary roller 3. The
auxiliaryroller 3 is journaled at its ends within 65
the notches 4 of the brackets 2. Revolubly
mounted upon the auxiliary member or
roller is a primary member or roller 5. The
primary member or roller 5 is preferably sub-
stantially elliptical-shape in cross-section, 70
Figs. 2 and 3, and comprises three sections
6, 7, and 8. These sections are integrally
connected by strips 9, which strips 9 are
formed in pairs.
Fixedly secured to the auxiliary roller 3 75
and between each two of the sections 6, 7,
and.8, is a spool 10. Each of the spools 10 is
provided with sides and a hub portion 11,
Fig. 3. A horizontal pin 12 is preferably
secured to each of the spools, and a tape 13 8o
is secured to the pin, in each instance. The
tapes 13 extend through apertures formed
in all of the slats 13a, Fig. 6. The lower ends
of the tapes are fixedly secured preferably to
the bottom of the lower slat, so that when 85
the tapes 13 are wound upon the spools 10,
the blinds or shades will be raised. Fixedly
secured to the primary member or outer
roller 9 are bands 14, which bands are con-
nected by horizontal strings 15. The slats 90
13a rest upon the horizontal strings 15, and
when the bands 14 on one side of the blind
are raised and the bands on the opposite side
are lowered, the blinds will be tilted or
closed. By moving the bands 14 so as to 95
place the slats 13a in a horizontal position,
the blind will be opened.
Positioned at one end of the primary
member or roller 5, and the auxiliary roller 6,
is a worm-gear device, which devices are roo
manipulated for imparting rotary movement
to said members or rollers 3 and 5. The
worm-gear device for actuating the inner or
auxiliary roller 3 is clearly depicted in Fig. 3,
and reference will be had more particularly 105
to this figure in the following specific de-
scription of said means for actuating the
roller 3. A disk gear 16 is fixedly secured to
the roller 3 near one end, preferably, through
the medium of a collar 17, Figs, 4 and 5. io
This gear is provided with teeth er' irely
around its periphery, and the teeth neshSpecification of Letters Patent.
