Improvements connected with Window Blinds.
I, ALFRED WOODBRIDGE LOVELAND, of Hawarden House, Thorpe Road, Norwich,
Printer, do hereby declare the nature of this invention to be as follows:-
This invention has for object, the construction and employment of fabric
paper or other sheet like material pleated accordion fashion and provided with
slots or holes which can be eyeletted or washered to strengthen same according to
the size of blind through which cords are passed from the lower part preferably
a slat of wood, a short length of bamboo cane, or the like, and over rollers at
the upper part, such as in or to brackets affixed preferably to a heading piece of
wood or other material. The cords have weights at their free ends to counter-
balance that of the blind and its fixings, so that the blind is held at any desired
height thereby without necessitating extra side cords and cord holders as with
wood and like Venetian blinds, the top or heading piece being attachable by
screws to the over rail of the window sash stile.
prefer that the guide rollers be swivelled to the brackets of which there
may be two or more according to the width of the canvas to suit the window
so that a pull on the weighted ends of the cords, say, by one hand simultaneously
said blind can be raised squarely the accordion pleats regaining their positions
during the lift action.
The canvas or sheet like material can be of any desired colour and is pre-
ferably pleated after. being cut for length and then is ready for attachment to
the head piece and lower slat, through which the cords are also run.

Improvements connected with Window Blinds.
I, ALFRED WOODBRIDGE LOVELAND, of Hawarden House, Thorpe Road, Norwich,
Printer, 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 has for object, the construction and employment of fabric,
paper, or other sheet like material pleated accordion fashion and provided with
slots or holes which can be eveletted or washered to strengthen same according to
the size of blind through which cords are passed from the lower part preferably
a slat of wood, a short length of bamboo cane, or the like, and over rollers at
the upper part, such as in or to brackets affixed preferably to a heading piece of

balance that of the blind and its fixings, so that the blind is held at any desired
height thereby without necessitating extra side cords and cord holders as with
wood and like Venetian blinds, the top or heading piece being attachable by
screws to the over rail of the window sash stile.
The canvas or sheet like material can be of any desired colour and is pre-
ferably pleated after being cut for length and then is ready for attachment to
the head piece and lower slat, through which the cords are also run.
My invention will be clearly understood by reference to the annexed drawings.
Figure 1 elevation of window blind complete. Figure 2 end view of same,
A, window blind of canvas or other material of sufficient stiffness to hold itself
in accordion pleats when creased in reverse order and at regular intervals or
distances apart. B, B, eyelet or other protected openings in each pleat for the
runner cords C, C, of which there may be one only and central if the bottom slat D
be weighty.
I have shown two runner cords for convenience, the upper ends of which are
rove over pulleys E, E, as single cords, but are preferably united by an attach-
ment to the counterbalance weight F from which is a single cord or tassel G
for action by a person when raising or lowering the blind.
It will be seen that the eyelet or other hole protectors of the pleats are from
both sides to prevent abrasion by the cords and where greater security and stiffness
is desired patches of vellum leather or the like can be pasted, glued, rivetted, or
otherwise fixed.
The blind if properly painted will give all the effect of slatted Venetian blinds
at considerably less cost and where such a blind is fitted inside a shop window, the
cords or cord can be led to a tube for manipulation without interfering with
the goods in the window.
In the drawing, I have shown the top edge of the accordion pleated blind
affixed to the upper strip or heading piece carrying the rollers, but it can be
secured to a separate strip suspended from the upper strip and this in con-
junction with the weight being carried from and by the balance and bottom
strip obviates all strain upon the blind itself, whether raised or lowered.
For carriage windows, the blind can be guided by wires or cords in end grooves
of the sash frame and so be prevented blowing inconveniently about.
The blind if properly made and hung has all the advantages of a close blind
with the appearance of the Venetian.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. The construction of window blinds of single sheets folded and creased on
the accordion creasing system with the facilities of raising and lowering the
same by cords like the slats Venetian blinds.
2. Accordion creased sheets as window blinds A in combination with eveletted.
or other protected holes B, cords C, roller pulleys E, counterbalance weight F.
all arranged for operation, as and in the manner described.
3. As material for window blinds, the employment of creased accordion pleated
sheet like material capable of the opposite faces folding to each and opening out
away from each other when operated by one or more cords, as set forth and sub-
stantially as represented.
