PROVISIONAL SPECIFICATION.
Improvements in Window Blind Rollers.
I HENRY GIBBS of Norton Villa Claremount Road Bristol in the County of
Gloucester Commercial Traveller do hereby declare the nature of my said invention
to be as follows:-
My invention has for its object improvements in Window Blind rollers which
obviate the objectionable necessity of tacking on the blind with tin tacks or
attaching them by tapes which also require tacking.
In carrying my invention into effect I form the roller in two halvos i.e. I split
it down the centre of its diameter and along the length of one of the halves I
insert a number of sprigs. so that the outside end projects from the straight side of the
half roller such sprigs being pointed and projecting so as to enter holes provided in
the other half of the roller. The end of the blind to be fixed is then pressed down on
to the sprigs and the two halves of the roller are placed together until they meet and
are firmly secured together by means of a metal cap at each end which is made to
slide on or off but fits sufficiently tight to be retained in its position although it may
be secured by a screw or other equivalent. These metal caps may be slotted so as to
allow of the blind being the full length of the roller running up to the head of the
cap and this slot by reason of the amount of spring it allows in the sockets of the
metal caps also assists in firmly retaining them in position.
The inside of the cap may be provided with a projection which slides in a groove
of the roller to prevent the cap from revolving on the roller.

COMPLETE SPECIFICATION.
Improvements in Window Blind Rollers.
I HENRY GIBBS of Norton Villa Claremount Road Bristol in the County of
Gloucester Commercial Traveller do hereby declare the nature of my said invention
& in what manner the same is to be performed to be particularly described &
ascertained in & by the following statement :-
My invention has for its object improvements in Window Blind Rollers which
obviate the objectionable necessity of tacking them by tapes which also require
tacking.
In carrying my invention into effect I form the roller in two halves i.e. I split
it down the centre of its diameter and along the longth of one of the halves I
insert a number of sprigs so that the outside end projects from the straight side
of the half roller such sprigs being pointed & projecting so as to enter holes pro-
vided in the other half of the roller. The end of the blind to be fixed is then
pressed down on to the sprigs and the two halves of the roller are placed together
until they meet and are firmly secured together by means of a metal cap at each
end which is made to slide on or off but fits sufficiently tight to be retained in
its position although it may be secured by a screw or other equivalent. These
metal caps may be slotted so as to allow of the blind being the full length of the
roller running up to the head of the cap and this slot by reason of the amount
of spring it allows in the sockets of the metal caps also assists in firmly retaining
them in position.

page_text: The inside of the cap may be provided with a projection which slides in a groove
of the roller to prevent the cap from revolving on the roller.
In order that my invention may be clearly understood & more easily carried into
practice I have appended hereunto a double sized sheet of drawings upon which I
have fully illustrated the nature of my said invention.
Figure 1 is an elevation of the two halves A and A' of the roller shewing the
blind B attached and the metal caps D and D' in position.
Figure 2 is an elevation of the two halves A. and A' of the roller with the blind B
and metal caps D & D' removed.
Figure 3 is a section through Figure 2 on the line 1-2 shewing the two halves of
the roller separated for attaching the blind.
Figure 4 is a similar section to Figure 3 but shewing the blind attached to the one
half A of the roller.
Figure 5 is a section through Figure 1 on the line 3-4.
Figure 6 is a similar section on the line 5-6.
Figure 7 is a similar section on the line 7-8..
I form my blind roller of two parts A and A' which is effected by dividing the
roller down at or near the centre of its diameter. Along the length of the flat face a²
of the one half A of the roller I insert a number of sprigs e with their points out-
wards upon which the end of the blind B, to be attached, is pressed as shown by
Figure 4 the other half A' of the roller being then pressed against the blind as shown
by Figure 5 the half A¹ of the rollor being provided with holes to receive & fit the
points of the sprigs e which project into it when the two halves A and A' are pressed
together. Each end of the roller is reduced at a³ to receive the sockets of the metal
caps D and D' which are made to slide on to the said end a³ thereby firmly securing
the two halves A and Aof roller together. These caps D and D' are made sufficiently
tight to be retained in their proper position while at work but if neccessary they may
be additionally secured by a small screw or other equivalent. The sockets of the
caps D&D are provided with slots d² and d³ so that the blind B may be the full
length of the roller and continue up to the head of the cap and these slots by reason
of the amount of spring they give to the socket of the cap assist in firmly retaining
the cap in position and at the same time allow of it being more readily removed
when required. A projection 4 is provided in the interior of the socket, which
projection engages with groove at formed in the roller to receive it thereby pre-
venting the cap from turning upon the roller.
The caps D&D' may be either cast stamped or otherwise manufactured and it
will be obvious that my invention can be applied to any particular class of mechanism
which it may be considerable desirable to use.
I may instead of dividing the roller down the centre of its diameter divide it
with rather more in the one half than the other and the sprigs e may be inserted
from the outside or inside as may be desired.
The rollers may be made of any class of wood or metal and instead of having
the caps to slide on to the end of the roller they may be made to screw on in
which case in sockets would not require to be so long.
In place of the sprigs e I may provide dowels or spikes secured in one half of
the roller & entering corresponding recesses in the other half and the blind may
be provided with cyclets to fit over the said dowols or spikes.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim iş :-
(1) The improvements in window blind rollers by which one part thereof is
removable to allow the end of the blind to be mounted between the two which
are kept together by the end mounts substantially as herein set forth and shewn
upon the drawings.

page_text: (2) The improvements in window blind rollers consisting of the roller in two
portions A and A' with sprigs e between and held together by the ends D and D'
substantially as herein set forth & shewn upon the drawings.
(3) In improvements in window blind rollers the caps D and D slotted at d²
substantially as & for the purpose herein set forth & shewn upon the drawings.
(4) The improvements in window blind rollers consisting of the roller in two
portions secured together by caps D & D¹ with dowels between in combination
with corresponding eyelets on blinds substantially as & for the purpose herein set
forth.
