PROVISIONAL SPECIFICATION.
Improvements in Window Blind Rollers and in the Manufacture of
the same.
I, JANE WILLIAMS, of 12, South Marine Terrace, Aberystwyth, in the County
of Cardiganshire, Widow, do hereby declare the nature of my said invention
to be as follows:-
My invention has for its object improvements in window blind rollers and
in the manufacture of the same by which I am enabled to effectually and easily
secure the blind to the roller without the use of tin tacks which are so
objectionable.
In carrying my invention into practice I form the roller to which the blind
is secured in two parts preferably hinged together and at the opposite edges
where the parts meet I form a rabbet. I then attach one or more V springs
to the faces where the parts of the rollers meet and these springs are so formed
that when the parts of the roller are closed together they snap or catch thus
firmly holding them together. When these springs are released they open the
parts of the roller so that the blind can be placed or laid between and when
the parts are closed again the blind is nipped and firmly held between the
rabbeted edges.
In some cases I may dispense with the hinges and connect the parts of the
roller together by a spring clip or clips fixed around the exterior which act as
a hinge and also for holding the parts of the roller together. Or a spiral spring
or springs may be fitted between the parts of the roller for the same purpose.
Or I may dispense with the use of springs and secure the parts together by
catches or their equivalents.
Improvements in Window Blind Rollers and in the Manufacture of
the same.
I, JANE WILLIAMS, Tyssel Villa, North Road, Aberystwyth, late of 12, South
Marine Terrace, Abberystwith, Widow, do hereby declare the nature of my in-
vention & in what manner the same is to be performed to be particularly
described & ascertained in and by the following statement:-
My invention has for its object imitirävements in window blind rollers and

page_text: in the manufacture of the same by which I am enabled to effectually and easily
secure the blind to the roller without the use of tin tacks which are so
objectionable.
In carrying my invention into practice I form the roller to which the blind
is secured in two parts preferably hinged together and at the opposite edges
where the parts meet I form a rabbet. I then attach one or more V springs
to the faces where the parts of the rollers meet and these springs are so formed
that when the parts of the roller are closed together they snap or catch thus
firmly holding them together. When these springs are released they open the
parts of the roller so that the blind can be placed or laid between and when
the parts are closed again the blind is nipped and firmly held between the
rabbetted edges.
In some cases I may dispense with the hinges and connect the parts of the
roller together by a spring clip or clips fixed around the exterior which acts as
a hinge and also for holding the parts of the roller together. Or a spiral spring
or springs may be fitted between the parts of the roller for the same purpose.
Or I may dispense with the use of springs and secure the parts together by
catches or their equivalents.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto two sheets of drawings upon
which I have illustrated examples of my improved window blind roller.
Figure 1 is a view of the roller complete shewing the blind fitted in position.
Figure 2 is a similar view to Figure 1 shewing the roller open with the blind
laid in position.
Figure 3 is an enlarged cross sectional view of Figure 1.
Figure 4 is a similar view to Figure 2 shewing the recesses a³ formed in the
projecting portion of the rabbet on the part A and provided with the hooked
spikes s on the part A¹ upon which the blind is hooked or attached.
Figure 5 is a cross sectional perspective view shew a portion of a modified
form of my blind roller.
Figure 6 is a cross sectional view of Figure 4 shewing the roller partially open.
Figure 7 is an enlarged view of the spring as shewn at Figures 5 and 6.
Figures 8, 9, 10 & 11 are views shewing further modifications of my blind
roller.
In carrying my invention into practice I form my blind roller in two parts
or sections A and A¹ and at one of the edges where these parts meet or come
together I form the rabbet a³ that is to say I cut a portion away on the edge
of one half into which a projecting portion on the other half fits as clearly shewn
on the drawings. I then connect the parts A and A together by the hinges B
the inner ends of which are curled over to form the spring catches and 62 so
that when the halves of the roller are closed together the catch clips the
catch thus holding the parts A and A' firmly together. The recesses a³ are
formed in the part A' or in the projecting portion of the rabbet in the part A
as shewn at Figure 4 for the catches b₁ to fit into so as to allow the two portions
of the roller to fit closely together. To fix the blind D the top edge is laid on the
part A over the catches 6 or on the part A¹ over the catches 62 Figure 4 then
the other part A or A¹ is closed upon it so that the catches 1 and 2 nip the
blind as well as the rabbet a² thereby firmly holding it between the sections
of the roller as clearly shewn at Figure 3. The recesses a are provided
so as to facilitate the opening of the parts A and A¹ when the blind is required
to be taken off the roller. In order to hold the blind in position on the part A¹
or A before these parts are closed together I fix the hooked spikes s to the
part A as shewn at Figure 4 or they may be fixed to the part A upon these
spikes the blind is hooked or attached thus holding it in position. In the
method as shewn at Figures 5, 6 and 7 instead of using hinge clips I employ
the V shaped spring clips E which are connected to the parts A and A¹ in a
similar manner as the hinges B. In this case I may or may not hinge the

page_text: sections of the roller together as the clips E act as catches and hinges if required.
The top edge of the blind is laid over these catches as shewn at Figures 6
spikes s being used if desired and when the sections of the roller are closed
together the edge of the blind is held by these catches in the recesses a³ as well
as by the rabbet a² as clearly shewn at Figure 5.
At Figure 8 I have shewn another form of spring clip for holding the parts A
and A¹ of the roller together. In this case I attach the curled spring clip F
to the exterior of the parts A and A¹ by screws or otherwise the exterior of the
roller where the spring clips F fit being preferably countersunk so as to make
the surface of the roller level. By this means the parts or sections of the roller
are firmly held together and when the blind is fitted in position the rabbet a³
prevents it from being withdrawn.
In the method as shewn at Figure 9 I connect the parts A and A¹ of the
roller together by the coiled springs H recesses h¹ being formed in either section
to receive the springs as shewn. In this case I may or may not hinge the sec-
tions of the roller together. Or I may hold the parts or sections A and A¹ of
the roller together by catches J as shewn at Figure 10 thus dispensing if
required with the spring hinges or springs only using ordinary hinges for hing-
ing the parts or sections of the roller together. It will be evident that in all
cases instead of forming the rabbet a² on the parts A and A¹ I may form the
rabbet a as shewn at Figure 11 so that when the blind is fitted into position
and the sections of the roller closed together the top edge of the blind is forced
into the groove on the one section by the projection on the other section thus
firmly holding it in position.
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:-
