Clock maker do hereby declare the naturo of this invention to be as follows:-
The object of my invention is to obtain a smooth certain and noiseless action in
rising and lowering Roller window Blinds. To effect this object I have a piece of Brass
Tubing about 3 inches long and at one end I have a flange to carry a endless Cord it
has a groove in it with points in, inside the Tube there is a spiral spring with a flat
surface at each end with a leather washer, I then insert a Screw with a square at one
end carrying a guide for the Cord with a washer also that passes through the flange
and also through the Spiral Spring. I screw a nut from the inside which Screw's the
Spiral Spring up this causes a tention either way you pull the Blind. The Square
goes in a Bracket one end of the Roller and a point the other.

page_text: I, THOMAS TURNER, of 44 Barnsbury Grove, Barnsbury, in the County of Middlesex,
Clock Maker, 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 my invention is to obtain a smooth, certain, and noiseless action in
raising and lowering roller window blinds.
To effect this object, I take a piece of tubing preferably brass, one end of which is
left open for its attachment to a blind roller, the opposite end has a flange or groove,
the bottom being provided with pins onto which the cord takes.
The flange end of the tube is closed except to a hole, through which a pin passes,
said pin having a square end exposed to engage in a bracket to hold it firmly. The
pin has also a collar with projecting and curved ends which overlap the groove and
serve to guide the cord.
Between this collar and the closed end of the tube, I arrange a leather washer and
another washer within the tube pressed against the inner face of the tube end by a
flat carried by a spiral spring which encircles the pin before mentioned.
The opposite end of the screw pin is screw threaded and a broad nut fitted thereon
puts pressure on the spring to keep the washers in close contact. This nut is within
the tube and the necessary tension is put upon the washers, so that whichever
blind is pulled the motion is perfectly noiseless and smooth.

the
My invention is shown in the annexed drawings, in which Figure 1 shows a
part sectional elevation of the tube A with the several parts in the position they
Occupy.
Figure 2 is an elevation of the same tube A attached to a blind roller B, the
opposite end of said blind roller having a point for rotating in a bracket when the
roller is turned.
The tube A has at its outer end, a flange or cord groove C, the bottom of which is
provided with pins as clearly indicated in Figure 2.
D is the plate forming the closed end of the tube A and E is a washer bearing on
the outer face thereof and between it and a collar F, this being on a pin G provided
on the outer end with a square H for fitting a hole in the bracket by which that end
of the roller is supported.
I is the inside washer bearing against the inner face of the closing plate D and
between said plate and a flat J under the pressure of a spiral spring K which encircles
the pin G and is enclosed within the tube A.
Lis a broad nut adjustable on the threaded end of the pin G for putting the
necessary tension between the plates J, F, the washers E, I, of which prevent noise
when the roller A, B, is rotated.

page_text: The collar F has two projections M, N, and their ends (one of which P only is seen)
are curled round to overlap the groove of the flange C and thus preserve the cord
within the groove of the flange.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The particular arrangement of roller end shown at Figure 1, in which leather
washiers are kept in contact with a plate forming the end of the tube and acted upon
by the pressure of the spring K as and for the purpose described.
