COMPLETE SPECIFICATION.
Improvements in Window Blind Rollers.
We, HENRY BOTELER COUCHMAN, of 40, Coten End, Warwick, in the County of
Warwick, Land Agent and Surveyor, and THOMAS ARCHIBALD HOPE, of 4, St. John's
Warwick, aforesaid, Gentleman, do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
Our invention has for its object improvements in window blind rollers which
obviates the objectionable necessity of tacking on the blind with tin tacks.
In order that our invention may be clearly understood we have appended here-
unto a double sized sheet of drawings upon which we have illustrated examples
of our blind roller.
Figure 1 is a view of our blind roller with the blind detached.
Figure 2 is a view of the roller with the blind attached shewing a portion of the
roller broken away.
Figure 3 is a view of a portion of the roller shewing the blind fixed so as to
wrap around a portion of the roller.
Figure 4 shews the rod which holds the blind in position on the roller.
Figure 5 is a perspective view of a modified form of our roller.
Figure 6 is a broken off view shewing another modification.
Figure 7 is an end view of a further modification.
In carrying our invention into practice we form the roller in two parts A and A¹
and these parts are fitted to the usual roller fittings B and B₁ leaving a sufficient
space between for the blind D to pass through. On the part A¹ we enlarge the
division of the roller so as to form the space a² which is sufficiently large to admit
the cross strip, bar, rod or tube, E or their equivalent. Or the space a² may be
formed partly on A and partly on A¹ if desired. When the parts have been fitted
together as shewn at Figure 1 the top end of the blind is passed between the
rollers and the strip E as shewn at Figure 4 is pushed into the seam d¹ formed
at this end of the blind, the blind is then pulled down until the strip rest in. the
space a as clearly shewn at Figure 2 by which means it will be readily under-
stood that the blind is firmly held to the roller. In some cases the blind may be
twice threaded through the space a5 in the roller and then the strip E inserted as
herein before described thus covering the front portion of the roller when the
blind is fully unwound as shewn at Figure 3.
At Figure
we have shewn a modified form of our roller. In this case we hinge
the parts A and A¹ together at a³ and form the slot or recess at in the part A¹ for
the strip E to fit into and when the blind is placed in position the part A is closed
over. This part A. when closed onto the part A¹ may be held by catches or bolts
or other means so as to prevent the strip from being pulled out of the recess a¹.
Instead of hinging the part A as shewn at Figure 5 it may be hinged at one
end to the part A¹ at a5 as shewn at Figure 6.
In the modification as shewn at Figure 7 we connect the parts A and A¹ together
by the struts F so that when the part A is pushed towards the right hand it
fits onto the part A¹ to which it may be secured by catches or bolts or their equi-

page_text: valents thus firmly holding the strip E to which the blind is attached in the groove
or recess a¹.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
CLAIMS.
First: The improvements in window blind rollers consisting essentially of the
parts A and A¹ which together constitute the roller and having a recess such as a³
in which the strip E fits and the blind being first threaded through the slot as
then the said strip is threaded through the seam d¹ in the top end of the blind in
the manner and for the purpose substantially as hereinbefore described and as
shewn upon the drawings at Figures 1, 2 and 3.
Second Securing blinds to their rollers by means of a slit or division in the
roller through which the upper end of the blind is threaded and the cross strip
bar rod or tube acting as a key E for locking the blind in position against with-
drawal in the manner substantially as herein set forth and as shewn upon the
drawings.
Third: In blind rollers as claimed in the first claim hinging or pivoting the
two parts together in in the manner and for the purpose substantially as herein
set forth and as shewn at Figures 5, 6 & 7.
Dated this 23rd day of December 1897.
