Complete Specification Left, 14th July, 1891-Accepted, 15th Aug., 1891
PROVISIONAL SPECIFICATION.
Improvements in Blind Furniture.
We, JOHN EMPSON, and JOHN HEWITT, trading as Wilkins and Wright, of
58 Graham Street, Birmingham in the County of Warwick, Manufacturers, do
hereby declare the nature of this invention to be as follows :-
In blind furniture and roller ends as at present constructed, great trouble is
occasioned by the metal flanges of such end fittings becoming bent and damaged
by slight blows or accidental knocks given during transit or when being removed
from the windows for cleaning or other purposes. Our invention is intended to
strengthen the blind furniture flanges without increasing or thickening the metal
employed for the purpose.
In carrying our invention into effect we construct our blind furniture or roller
ends in any usual or well known manner, and we form the flanges or discs forming
the ends out of sheet metal. We do not make the surfaces of such ends or flanges
plain, but we form such with a number of corrugations or ribbed projections and
recesses arranged thereupon for strengthening and stiffening purposes.
We stamp
the metal discs or flanges of the blind furniture, with radial serrations or corruga-
tions provided upon our tools, so that the operation of pressing or stamping such
articles is not rendered more costly by reason of our improved corrugated or
serrated form of surface.
We do not limit our form of corrugation or stiffening surface to any arrange-
ment of radial lines upon such surfaces, but we construct our furniture with the
ribs or corrugations arranged concentrically, irregularly or in any other form, or
any floral or fancy design of surface to suit any particular requirement upon any
suitable kind of metal with like advantage in respect to producing a stiffened form
of furniture.

COMPLETE SPECIFICATION.
Improvements in Blind Furniture.
We, JOHN EMPSON, and JOHN HEWITT, trading as Wilkins and Wright, of
58 Graham Street, Birmingham, in the County of Warwick, Manufacturers, 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:-
In blind furniture and roller ends as at present constructed, great trouble is
occasioned by the metal flanges of such end fittings becoming bent and damaged
by slight blows or accidental knocks given during transit or when being removed
from the windows for cleaning or other purposes. Our invention is intended to
strengthen the blind furniture flanges without increasing or thickening the metal
employed for the purpose.
In carrying our invention into effect we construct our blind furniture or roller
ends in any usual or well known manner, and we form the flanges or discs forming
the ends out of sheet metal. We do not make the surfaces of such ends or
flanges plain, but we form such with a number of corrugations or ribbed projections
and recesses arranged thereupon for strengthening and stiffening purposes. We

corrugations provided upon our tools, so that the operation of pressing or stamping
such articles is not rendered more costly by reason of our improved corrugated or
serrated form of surface. We do not limit our form of corrugation or stiffening
surface to any arrangement of radial lines upon such surfaces, but we construct our
furniture with the ribs or corrugations arranged concentrically, irregularly or in
any other form, or any floral or fancy design of surface to suit any particular
requirement upon any suitable kind of metal with like advantage in respect to
producing a stiffened form of furniture.
In the accompanying sheet of explanatory drawings Figure 1 is an elevation of
a blind roller showing our improved furniture or ends attached thereto. A being
the flange of metal having corrugations a formed thereon for stiffening purposes as
hereinbefore described. The corrugations or ribbed surface on both the end
flange Band the cord barrel flanges A we stamp radially as indicated, with the
grooves of any convenient or required depth.
We sometimes stamp the flanges with concentric rings or corrugations as shown
on Figure 2, A' being the cord barrel flanges with the ribbed rings a', and B' the
roller end flange with the corresponding rings 6. We arrange the rings preferably
in such a manner that the surface is equally curved in and out on both sides of the
plates or flanges.
Figure 3 illustrates another form of our improved flange A2, B2 having curved
ribs a², 2, arranged thereon.
Figure 4 represents our improved roller flanges A³, B3, with the depressions, and
corrugations a³, 63, arranged in an ornamental manner so that the configuration of
the surface produces ribs of metal to strengthen the flanges as hereinbefore set
forth.
We employ any suitable kind of metal or other material for our improved
fittings and mountings, and we arrange the barrel to hold the cord to suit any kind
of roller such as C or any ordinary form of bracket such as D without departing
from the essential features of our invention as before described and as set forth.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
(1) The construction of blind furniture ends and roller flanges, with corrugated
or serrated surfaces, as and for the purposes hereinbefore described.
(2) The construction of blind furniture flanges, having ribs or serrations
formed thereon for strengthening purposes substantially as hereinbefore described
and as illustrated in Figures 1, 2, 3, and 4 of the accompanying drawings.
