JAMES E. OR, OF DALLAS, TEXAS.
WINDOW-SHADE GUIDE.Specification of Letters Patent.
Patented Dec. 2, 1919.
Application filed February 20, 1919. Serial No. 278,312.
To allwhom it may concern:
Be it known that I, JAMEs E. ORR, a citi-
zen of the United States, residing at-Dallas,
in the county of Dallas and State of Texas,
5 have invented certain new and useful Im-
provements in Window-Shade Guides, of
which the following is a specification.
This invention relates to new and useful-
improvements in guides for window shade
10 rollers.
It is practically impossible to hang a
window-shade roller so that the shade will
wind and unwind without creeping toward
one end of the roller and engaging the sup-
15 porting bracket. If the roller is hung ex-
actly level the settling of the building or
the swelling of the wood in damp weather
will displace it. Many persons catch hold
of a shade at one side to raise or lower it.
20 The frequent contact of the edges of the
shade of the brackets soon wears and tears
the shade so that it must be replaced or is
very unsightly.
My invention contemplates a simple at-
25 tachment which may be applied to each end
of the roller whereby the latter is converted
into a spool and the shade smoothly and
evenly wound and unwound without injury.
In carrying out the invention a collar is
30 formed and provided with means for fasten-
ing it on the end of a roller in close relation
to the end of the shade wound on said roller.
The collar is provided with a convex face
next to the end of the shade which acts to
35 guide the shade into position as the roller
is revolved.
The invention will be more readily under-
stood from a reading of the following speci-
fication and by reference to the accompany-
40 ing drawings, in which an example of the
invention is shown and wherein:
Figure 1 is a view of a roller equipped
with guides made in accordance with this
invention, the shade being shown in section,
45 Fig. 2 is rear elevation of. the collar,
Fig. 3 is a side elevation of the same,
Fig. 4 is a sectional view of a modification,
Fig. 5 is rear elevation of the same,
Fig. 6 is a rear elevation of another form,
50 Fig. 7 is a sectional view of the same,
Fig. 8 is a view of still another form, and
Fig. 9 is a rear elevation of the same.
In the drawings the numeral 1 designates
an annular concavo-convex collar having aconvex face 2 and provided with a central 55
circular opening 3 large enough to receive
the end of a window shade roller A.
In Figs. 1, 2 and 3 the collar has an out-
wardly bent lug 4 at its opening and on the
concaved or rear side. The lug carries a 60
set screw 5 which has its inner end battered
to prevent displacement from the lug when
not in use. The collar is slipped on the end
of the roller A so that its convex face 2 is
in juxtaposition to end of the shade B wound 65
on the roller. By tightening the screw
against the roller the collar is fastened in
place.
The collars are fastened on each end of
the roller as is shown in Fig. 1 and when 70
the roller is revolved to wind or unwind the
shade the convex faces 2 will guide the
shade to a central position if said shade
tends to wind or unwind toward either end.
The faces 2 flare outward and thus do not 75
interfere with the operation of the shade
but if engaged by the edges of said shade,
act to displace said edges inward flush with
the ends of the roll of shade on the roller.
The lug is bent out enough to permit the 80
inner battered end of the screw to clear the
roller as the collar is slipped on or off of
the said roller.
It is obvious that various means for fas-
tening the collar on the roller could be 85
evolved and I have worked those forms
which I consider most practical.
In Figs. 4 and 5 I have shown a collar in
which the central opening 3 is surrounded
by a plurality of inwardly directed radial 90
teeth 6 having their points bent slightly
rearward and terminating in a circle of
slightly less diameter than that of the roller
on which the collar is placed. The rear-
wardly bent points permit the collar to be 95
easily slipped onto the. roller, but any tend-
ency toward displacing the collar outward
or rearward causes the points to bite into
the roller.
In Figs. 6 and 7 the collar has an out- 100
wardly bent clamping ring 7 surrounding
the opening 3 and having its ends 8 cut free
from the collar and provided with ears 9
receiving a screw 10 by which the ears may
be' drawn together and the free ends 8 105
clamped about the roller.
In Figs. 8 and 9 a slightly tapered and
externally threaded split sleeve 12 is1,323,646. .
