Improvements in and connected with Window Blind and other
Rollers, and in the Manner of Attaching Blinds and the like
thereto.
We, EUGENE BOLAND NASH of Fernwood Merthyr Tydfil in the County of
Glamorgan Commercial Traveller, and RACHAEL CECILIA EVANS of 4 Gwaloedygarth
Villas Merthyr Tydfil, Spinster, 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 :-
The object of this invention is to enable window blinds maps and the like to be
easily attached to or detached from the rollers and to dispense with the nails or tacks
ordinarily used to attach such blinds maps and the like to the rollers. And in order
that our said invention may be fully understood we will proceed to explain the same
with reference to the accompanying sheet of drawings in which :-
Fig. 1 represents elevation of a window blind roller constructed according to this
invention.
Fig. 2 is cross section of same looking towards the cord pulley.
Fig. 3 is cross section of same looking towards fitting at the other end of the
roller.
Fig. 4. is longitudinal section shewing method of securing the blind to the roller.
Fig. 5 is part longitudinal section shewing a modification of the invention.
Fig. 6. is cross section of same.
The same letters denote the same parts in all the figs.
Now according to this invention we form a longitudinal groove a in the roller b of
any convenient depth and width which groove preferably extends the whole length
of the roller as this method of construction allows of the rollers being made in a
continuous length and afterwards being cut to size.
To the inside of the cord pulley c or to the roller b itself we attach a piece of
metal or other suitable material d about from a quarter of an inch to half an inch
in width and long enough to cover the groove a as shewn at Fig. 2. The piece d
projects over the groove see Fig. 1. A similar piece of metal or other suitable
material f is secured to a piece of suitable material g which rotates on the fitting h
at the other end of the roller.
As will be seen from inspection of Fig. 4 the fitting his provided with a socket k
to receive the end of the roller b. The socket is provided with a flange extending
partly round the socket the piece g being secured to the socket by the said flange.
The piece g is preferably made so as to move rather stiffly between the fitting h
and collar so as to prevent it from moving when the blind is secured to the roller
or any suitable locking device may be employed for this purpose for example the
fitting h may have a groove therein with which a projection on the piece 9 engages
where the blind is secured in the roller. Or the fittings at the end of the roller b
may be made with sockets to receive the ends of the roller one or both of the sockets
being cut away at the groove as shewn at Figs. 5 and 6.
m m are locking rings rotating on the said sockets the said rings being also cut
away as shewn at Fig. 6.

page_text: n is a lug or handle by means of which the piece g or rings m may be rotated.
We provide also a lath p of the same length as the body of the roller (inside the
fittings) of approximately the same depth as the groove a and slightly narrower than
the said groove.
The blind q instead of being only furnished with the usual hem at the bottom to
receive the ordinary blind stick is provided with a similar hem at the top to receive
the lath p which when inserted in the said he projects slightly over each side of
the blind.
The hem at the top of the blind when the lath p is inserted therein is placed in
the groove a and retained therein by rotating the piece g or the rings m until the
lath is prevented from coming out of the groove by the piece for the ring m closing
the end of the groove as shewn at Figs. 1, 3, 4, and 5.
By turning the piece g or the rings m until the piece f is on one side of the
groove or the apertures in the said rings coincide with the groove a (see Fig. 6)
the blind can be instantly detached from the roller without removing the roller
from the brackets and no nails or tacks are required to secure the blind to the lath
or roller.
Maps Charts and the like can be attached to rollers in the manner herein before
described for blinds.
To secure blinds such as those used in Public Vehicles from being stolen and to
prevent the laths of long blinds from sagging in the middle one or more screws may
be inserted through the roller into the lath for extra security.
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 :-
1. In a roller for blinds maps and the like the combination of a longitudinally
grooved roller a lath inserted in the hem of the blind and fitting the said groove and
a means for securing the said laths in the groove substantially as hereinbefore
specified and for the purpose stated.
2. In a roller for window blinds maps and the like the combination of a roller b
having a longitudinal groove therein with a lath p approximately fitting the said
groove a piece d on the cord pulley and a piece g rotating on the fitting h and having
a piece formed in one with or attached to the piece g all substantially as herein-
before specified and for the purpose stated.
3. In a roller for window blinds maps and the like the combination of a roller b
having a longitudinal groove a therein with a lath p approximately fitting the said
groove and one or more locking rings m rotating on one or both of the fittings c and h
all substantially as herein before specified and for the purpose stated.
4. Rollers for window blinds maps and the like constructed as shewn by the
accompanying drawings.
