Improved Device for Securing Shades, Maps, and other like Objects
to Rollers.
I, PHILANDER ABBEY HARRIS, of No. 26 Church Street, in the city of Paterson,
County of Passaic and State of New Jersey, United States of America, Physician,
do hereby declare the nature of this invention, and in what manner the same is to
he performed to be particularly described and ascertained in and by the following
statement
My invention relates to an improved means for securing window shades, curtains,
maps and other like objects to the rollers or sticks upon which the same are wound;
and the object of my invention is to provide a device which shall prevent the shade,
curtain or map being torn from the roller or stick, when it is being unwound.
The means I employ for accomplishing this are shown in the accompanying
drawings, in which, Figure 1 is a perspective view of a portion of a roller and its
shade, the latter being unwound almost its entire length, showing my improved
device attached.
Figure II is a view showing the device in a modified position.
D. is
A. is an ordinary spring roller; B. is the shado or curtain; C. is a flexible band
or cord, one end of which is attached to the roller and the other to the shade;
the place of attachment of C. to the roller A; E. is a device for fastening C. to the
shade B.
The length of C. and the place where it is secured to the roller A. must be such
that, as the shade is unwound and just before there begins to be a strain upon the
nails or other devices which fasten the shade to the roller, the band or cord C. will be
drawn taut and begin to be wound upon the roller.
The devices E. are made as shown in the drawings for the purpose of obtaining a
firm and extended hold upon the shade. But this particular form is not essential.
Any suitable device may be used, or the band or cord C. may be sewed to the
shade.
The working of the device will now readily be understood. By referring to the
drawings it will be seen that as the shade is unwound, and just before it is pulled out
its entire length, the band or cord C. begins to wind upon the roller in the opposite
direction, and at that moment arrests the shade in its downward movement. Thus
the unwinding of the shade is arrested before there is any strain upon the nails, or
other fastenings, which secure the shade to the roller, and the shade cannot easily be
torn from its roller.
The band C. may be flat, as a tape, or it may be a cord, as shown in the drawings.
It may be made of some textile fabric, or it may be of flexible metal or other material.
It may be secured to the roller and the shade in any known manner, bearing in mind
not to make the point of attachment to the shade too small, lest the shade bo torn.
The band C. may be single, as shown at 1 and 3 in Figure I, or it may be double,
passing around the roller and having both ends fastened to the shade as shown at 2
and 4 in Figure I. Again the band or cord C. need not necessarily hang perpendicu-
larly from the roller, but it may have the position shown in Figure II. In this
Figure the construction is similar to that shown at 4 in Figure I, except that instead
of the cord C. hanging perpendicularly from the roller A, and having both its ends
fastened to the shado B. at the samo place, the said cord is passed obliquely over the
roller and its two ends instead of being together, as in Figure I, are secured to the
It will be seen that instead of
shade at points widely separated from one another.
having a series of these short bands or cords, one long cord may be used having one
end fastened to the shade near one edge and the other near the opposite edge. In

page_text: such a case intermediate points of the cord must necessarily be fastened to the shade,
as shown in the drawing, thereby permitting the cord to be passed back and forth
over the roller, as stated and shown.
Of course any number of bands may be used on one shade.
In order to prevent a too sudden arresting of the downward movement of the
shade, the cord or band C. may be made slightly elastic by the insertion of rubber,
or in any other known manner. In the case of the cord shown at 4 in Figure I,
this clastic effect will be obtained by simply twisting the cord before fastening its
ends to the shade.
In the drawings, I have shown the fastenings E. as strips of punctured metal,
but the band or cord C. may be secured to the shade by sewing or in any other suit-
able manner.
Although, for convenience, I have shown a spring shade-roller in the drawings,
any kind of a roller may be used. Likewise my improved dovice may be employed
in cases where maps and other like objects are wound upon the roller, as well as in
the case of shades and curtains.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the samo is to be performed, I declare that what I
claim is ;
1. In a shade, or inap, roller, the combination of the roller, the shade, or map,
attached thereto, and a flexible band or cord attached to the roller and also to the
shade, or map, the point of attachment of said cord to the latter being, just before the
shade, or map, is entirely unwound, nearer, perpendicularly, to its point of attach-
ment to the roller than to the point, measured along the shade, or map, where the
latter is attached to the roller, whereby the cord is drawn taut and strain upon the
shade, or inap, at its points of attachment to the roller is prevented, substantially as
shown and described.
2. In a shade, or map, roller, the combination of the roller, the shade, or map,
attached thereto, and a flexible band or cord suspended upon said roller and having
its ends attached to the shade, or map, the points of attachment of said cord to the
latter being, just before the shade, or map, is entirely unwound, nearer, perpendicu-
larly, to the points where the said cord is tangent to the sides of the roller than to
the point, measured along the shade, or inap, where the latter is attached to the
roller, whereby the cord is drawn taut and strain upon the shade, or map, at its points
of attachment to the roller is prevented, substantially as shown and described.
3. In a shade, or map, roller, the combination of the roller A. with its attached
shade, or map, B. and the band or cord C. one end of the latter being attached to
the roller A. and the other end to the shade, or map, B. the latter point of attach-
ment being, just before the shade is entirely unwound, nearer to the point of attach-
ment of the cord to the roller than to the point, measured along the shade, or map,
where the latter is attached to the roller, whereby the cord is drawn taut and strain
upon the shade, or map, at its points of attachment to the roller is prevented, substan-
tially as shown and described.
4. In a shade, or map, roller, the combination of the roller A. with its attached
shade, or map, B. and the band or cord C. which latter is hung upon the roller A.
and has both its ends attached to the shade, or map, at the same place, the latter
points of attachment being, just before the shade, or map, is entirely unwound,
nearer to the points where the said cord is tangent to the sides of the roller than to
the point, measured along the shade, or map, where the latter is attached to
the roller, whereby the cord is drawn taut and strain upon the shade, or map,
at its points of attachment to the roller is prevented, substantially as shown and
described.
5. In a shade, or map, roller, the combination of the roller A. with its attached
shade, or map, B. and the band or cord C. the latter passing obliquely over the
roller and having its ends attached to the shade, or map, at different points upon

same,
the latter points being, just before the shade is entirely unwound, nearer,
perpendicularly, to the points where the said cord is tangent to the sides of the
roller than to the point, measured along the shade, or map, where the latter is attached
to the roller, whereby the cord is drawn taut and strain upon the shade, or map,
at its points of attachment to the roller is prevented, substantially as shown and
described.
