PROVISIONAL SPECIFICATION.
Improvements in Rollers for Blinds and the like.
I, THOMAS FREDERICK BURROWs of Wellington Road, Newark on Trent, in
the County of Nottingham do hereby declare the nature of this invention to be as
follows: :-
This invention for improvements in blind rollers has for its object to provide
improved means for retaining the blind on the roller without stitching or the use
of tacks or the like; and consists essentially in providing the roller with a longi-
tudinal groove wider at the base than at the mouth. To secure the blind a round
or other rod is inserted in a fold in the material and the whole inserted end wise in
the groove. In order to facilitate removal of the blind the flange of the end fitting
is made detachable or the flange may be slotted and the slot covered by a hinged
or pivotted plate.

COMPLETE SPECIFICATION.
Improvements in Rollers for Blinds and the like.
I THOMAS FREDERICK BURROWs, of Wellington Road, Newark-on-Trent, in
the County of Nottingham, 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 for improvements in rollers for blinds and the like has for its.
object to provide improved means for retaining the blind in the roller without
stitching or the use of tacks or the like; and consists essentially in providing the
roller with a longitudinal groove wider at the base than at the mouth. To secure
the blind a round or other rod is inserted in a fold in the material and the whole
inserted endwise in the groove. In order to facilitate removal of the blind the
flange of the end fitting is made detachable or the flange may be slotted and the
slot covered by a hinged or pivoted plate.
In the accompanying sheet of illustrative drawings, Fig. 1 is an elevation partly
in section of a blind roller constructed according to this invention, and Figs. 2
and 3 are cross sections of the same.
A. dovetail groove a is cut in the wooden roller b. One end of the roller is.
provided with any usual fitting c by which it is manipulated. The other end of
the roller is fitted with a disc d secured to its end by the screws e and provided
with the central screw pivot which is riveted to the disc or may be in one with
it. The disc d has a dovetail recess g corresponding to and forming a continuation
of the groove a in the roller. The flange his screwed on the pivot and has a
projecting ring 1 fitting over the end of the roller b.
To secure a blind to the roller, the top end of the blind m is folded over the
small gripping roller and the flange being removed, the whole is inserted.

page_text: end wise into the roller; and the flange h is screwed into position and prevents any
end wise motion. It will readily be seen that the blind is gripped automatically
and that the greater the strain on the blind the greater the gripping power. If
desired the roller n may be a lath of a similar shape to the groove, but smaller.
I am aware it is not new to have a hole in the roller and a small slit leading
from the circumference to the hole but hitherto in such cases it has been necessary
to insert the small roller n into a fold in the top edge of the blind or otherwise
secure it to the blind, consequently the blind cannot be adjusted when once the
fold is sewn so as to draw up straight. In adjusting the roller to the proper length
it is preferable to cut off from the end on which the usual fitting o is fixed.
The dovetail groove may conveniently be cut by two saws inclined to one
another and arranged one behind the other, or it may be cut at two operations with
a single saw by fixing the roller in an inclined base and passing it to the saw
first one end first and then the other end first.
Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed, I declare that what 1
claim is:
"
1. A roller for blinds or the like provided at its circumference with longitudinal
retaining groove wider at the bottom than at the mouth and a gripping lath or
roller adapted to automatically wedge the edge of the blind or the like in the
groove.
2. A roller for blinds or the like with a gripping lath or roller substantially as
described with reference to the drawings.
3. A roller for blinds or the like with a gripping lath or roller substantially as
described with referenco to the drawings and fitted with an end adapted to allow
the blind and the like and its gripping lath or roller to be readily inserted
end wise.
