PROVISIONAL SPECIFICATION.
Improvements in and connected with Roller Blinds.
I, HERBERT SMITH of Malvern House, Matlock Bank, in the County of
Derby, Bath Attendant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to means and devices for securing blinds to rollers in a
simple and efficient manner without the use of tacks and the like.
In carrying out my invention, I form a hem on the end of the blind, and in this
I insert a wire, rod, lath, tube or the like. The hem with the article inserted
therein is held upon or in the roller by means of one or more slit tubes, through
the slit of which the blind passes from the roller. The turning of the slit tubes
may be prevented by forming therein projections adapted to fit in corresponding
recesses in the roller, or by means of pins screws or similar devices.
When, as is at present generally preferred, there is one of the slit tubes at each
end of the roller, the outer ends of these tubes may be fitted with wood plugs upon
which the usual pivots may be fixed, or instead of the wood plugs, metal roller
ends may be secured upon the outer ends of the slit tubes.
In the case of a spring roller, and in cases where the article inserted into the
hem of the blind is of considerable diameter, the outer part of the roller may
consist of a shell longitudinally formed in halves and held together by the slit
tubes or by an equivalent device, the blind passing out through the parting of the
shell and the slits of the tubes. With short rollers, the divided shell may be held
together at the ends by bands and the slit tubes may be dispensed with.
In ordinary blind rollers, it is necessary only to form thereon or therein a flat,
recess, groove or the like to receive the hem with its inserted article, and to employ
therewith one or more of the slit tubes.

Improvements in and connected with Roller Blinds.
I, HERBERT SMITH of Malvern House, Matlock Bank, in the County of
Derby, Bath Attendant, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to means and devices for securing blinds to their rollers
in a simple and efficient manner and without the necessary use of tacks and the
like.
In carrying out my invention I form a hem upon the upper end of the blind,
and within this hem 1 insert a wire, rod, lath, tube or the like. This hem having
the wire or other article therein, is held upon or in the roller by means of one or
more slit tubes or equivalent clamps, through the slit or opening of which the

page_text: blind passes from the roller. The turning of the slit tubes upon the rollers may
be prevented, when desired, by forming therein projections adapted to fit in
corresponding recesses in the rollers, or by means of pins screws or similar
devices.
I will more particularly describe in what manner I prefer to carry my invention
into effect, with reference to the accompanying drawings.
Figure 1 represents an elevation of a blind roller, with a blind attached thereto
according to this invention. The central part of the roller and blind is represented
as being broken away to economise length, and the upper part of the blind only is
indicated. The roller furniture illustrated is of an ordinary known construction,
and the roller is an ordinary round wooden roller. Along the upper edge of the
blind a hem is sewn, in which a wire A is inserted. In common blinds this hem may
be identical in form with the ordinary hem at the bottom of the blind, so that the
blind may be reversed if desired. In this case, the blind C is held upon the roller
by means of the slit tubes or clamps B, of which there may be two or more.
clamps Beach cover rather more than one half the circumference of the roller
and are preferably made of a springy metal such as hard rolled sheet brass, so
that they may be sprung upon and off the roller. The upper edge of the blind
having been placed upon the roller and nearly one turn of the blind round it
having been made, the clamps are sprung on as indicated by Figure 3, which
represents a cross section of Figure 1.
The
An end elevation of the roller is shewn
by Figure 2. If preferred, a groove may be made longitudinally in the roller
into which the hein and its contained wire can fit, but this is not necessary.
Instead of two or more of the clamps, a single long one may be employed, but
this is much less convenient in use. The clamp or clamps B may be additionally
secured upon the roller R by means of a flat headed pin P in each clamp.
In the modification represented in elevation by Figure 4 and in cross section by
Figure 5, the roller R has no pulley or flange at one end, at least, so that the
clamps may be slided endwise upon the blind and roller. In this case the clamps
may be nearly a complete circle as indicated. This modification may be employed
more particularly with spring rollers.
In the further modification illustrated similarly by Figures 6 and 7, a single
clamp having about the same length as the roller, is used, and is slided upon the
roller from one end.
When there is one of the clamps at each end of the blind roller, and in the case
of a single clamp extending to each end of the roller, the outer ends of the clamps
may be fitted with the pivots or roller ends, if it be desired.
When a groove or recess is formed in the roller for the reception as hereinbefore
described, of the hem and its contained wire or the like, a single short clamp at
about the centre of the roller will suffice, but this arrangement does not lend itself
so readily to adjustment of the "hang" of the blind as do the forms and arrange-
ments illustrated.
It will be seen that the hem with its contained wire or other article, coming
into the opening between the two edges of the clamp, effectually prevents the
blind being pulled off the roller, and that by a slight adjustment of this hem
relatively to the clamps and roller, the blind may be caused to hang perfectly,
even if the hem be not true. Also, that the blinds may be readily removed and
replaced, and, if the bottom and top hems are similar, as they should be, the
blind may be reversed equally readily.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. The hereinbefore described means for securing blinds to their rollers and
which consist essentially of a hem in the upper edge of the blind in which a wire
or the like is inserted, and a curved clamp or clamps constructed to fit upon the
roller, the blind being held between the clamp and the roller with its hem between

page_text: VIC edges or
the clamp, substantially as set forth and as illustrated by the
accompanying drawings.
2. Tubular clamps for securing blinds upon their rollers constructed and
arranged substantially as hereinbefore described and as illustrated by the accom-
panying drawings.
