Improvements in the Heads of Venetian Blinds and the like.
I, EDWARD WILLIAM FISHER, of 383, Romford Road, Forest Gate, in the County
of Essex, Blind Maker, do hereby declare the nature of this inven.ion to be as
follows:-
The object of my invention is so to construct and fit the heads of Venetian
blinds and other like blinds that the same shall be extremely cheap and simple
in construction very convenient and adaptable in use and highly efficient and
certain in operation.
To carry out this object the head is made in the usual manner of wood or other
suitable material and of the proper dimensions as may be required in each case.
Along the central part of the upper surface of this head is most conveniently
ploughed or made a shallow groove of the desired width and from two or more
suitable positions in this head is suspended in the usual manner the upper lath
of the Venetian blind or the like wherefrom are suspended the other laths of the
blind by ladder-tapes cr other ordinary and appropriate appliances. In the
usual and corresponding positions in respect of such ladder-tapes or appliances
or elsewhere vertical holes are made through the head wherethrough the blind
cords can severally pass down to the blind in the ordinary manner while near
one end of the head a proper number of vertical holes whether one for all the
blind cords or one for each blind cord or otherwise can be made wherethrough
these blind cords.can pass up from the operating position to pass along above
the head previous to passing down to the blind in the ordinary manner. Near
each hole and on the proper side of the same is made in the head a recess wherein
can be mounted a roller of the desired length and diameter arranged transversely
and horizontally across the head and at the proper elevation and position to reduce
the friction. or chafing of the blind cords that pass over them to a minimum.
These rollers may be cylindrical or they may have peripheral and circumferential
grooves or depressions on their surfaces corresponding to the number of blind
cords, that will pass over them but whatever may be such number only one roller
is provided therefor. A convenient method of placing each roller in position
consists in horizontally boring a large hole in one side of the head wherethrough
the roller can he passed into its desired position when its axis or central shaft
can be passed through the roller and forced into the head on the other side while
a suitable ring or washer or sleeve can he passed on the rear end of the axis or
shaft and entered into the hole on this side of the head to fill the same and duly
to support the end of such axis or shaft and these rollers and their axes or shafts
and the rings or washers thereof may be made of metal or wood or other suitable
material in any convenient and usual or other manner.

I, EDWARD WILLIAM FISHER, of 383, Romford Road, Forest Gate, in the County
of Essex, Blind 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 this my invention is so to construct and fit the heads of Venetian
blinds and other like blinds that the same shall be cheap and extremely simple
in construction very convenient and easily adaptable for and to all manner of
positions in use and highly efficient and certain or not at all likely to get out
of order in operation.
In order the more clearly to explain my invention and in what manner the same
is to be performed I refer to the accompanying drawing wherein Figure 1 is a plan
of the top side of this my head as fitted and arranged for a Venetian blind
Figure 2 is a longitudinal section of this head and Figure 3 is a transverse
section of the same on an enlarged scale.
The head A is made in any usual manner of wood or other suitable material
and of the appropriate dimensions as may be required in each particular case
and for any particular blind and along the central part of the upper surface of
this head A is ploughed or made a shallow longitudinal groove or trough B of the
desired width and depth.
From two or more suitable positions C in the length of the head A is suspended
in the usual manner the upper lath or slat. of the Venetian blind wherefrom
are suspended the other laths or slats of the Venetian blind by the usual ladder-
tapes or other ordinary and appropriate appliances or it may be in the case of
other blinds from the underside of the head A is suspended or to the same is
attached or connected the upper edge or the top part of the particular blind that
is to be fitted and used in this particular case. In the usual and corresponding
positions in respect of such ladder-tapes or other appliances or, elsewhere in the
length of the head A as may be convenient and suitable in respect of the particular
blind vertical holes D are made through the head A opening into the groove B
therein through which holes D the blind cords E can severally pass down to the
blind in the ordinary manner being fitted thereto and connected and arranged
therewith in any manner as may be customary and convenient in respect of any
particular blind. Near one end of the head A may be similarly made one large
vertical hole D for all the blind cords E or as is perhaps preferable and as is
shewn in the drawing a proper number of smaller vertical holes D₁ are similarly
made in this position through each of which it may be only one blind cord E can
pass up from the position where these blind cords E are to be operated and
controlled in any usual manner to pass along above the head A. in the groove B
therein previous to passing down to the blind in any ordinary manner.
+
Near each hole D and on the proper side of the same is made in the head. A
a recess F. wherein is mounted a roller G of the desired length and diameter
arranged transversely and horizontally across the head- A and at the proper eleva-
tion and position to reduce the friction or chafing of the blind cords E that pass
over them to a minimum by raising such blind cords E properly free from and
off and above the bottom of the groove B and by leading the same freely and
clearly through the holes D. These rollers G may be cylindrical or as is perhaps
preferable and as is shewn in the drawing they may have peripheral and circum-
ferential grooves or depressions in or on their surfaces corresponding it may be
to the number of blind cords E that will. pass over them but whatever may be

page_text: such number of blind cords E only one roller G is provided therefor in the one
position.
A very convenient and appropriate method of placing each roller in position
is shewn in the drawing according into which a large hole or recess F is bored
or made horizontally and transversely in one side of the head A in the proper
position wherethrough the roller G can be introduced and passed into its appro-
priate and desired position when its axis or central pin or shaft H can be passed
loosely through the roller G and its inner end can be forced into the head A on
the other side at the end of the recess F while a suitable ring or washer or
sleeve K can be passed on and over the rear and outer end of the axis H and
entered into the open end of the recess F on this side of the head A to fill the
same and constitute a plug therefor and at the same time duly to support this end
of the axis H and retain the same together with its roller G securely and properly
in position. These rollers G and their axes H and also the rings K may be made
of metal or wood or any other suitable material in any convenient and usual or
other manner as may be expedient or desirable in each particular case.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
The arrangement and combination of parts and appliances constituting my
improvements in the heads of Venetian blinds and the like substantially as herein-
before described and shewn in the accompanying drawing.
