Year: 1881

page_text: LETTERS PATENT to Henry Tylor, of 28 and 30, East Road, City Road, in
the County of Middlesex, Venetian Blind Manufacturer, for an Invention of
"AN IMPROVEMENT IN VENETIAN BLIND ACTIONS AND THEIR HEAD LATHS."
PROVISIONAL SPECIFICATION left by the said Henry Tylor at the Office
of the Commissioners of Patents on the 5th January 1881.
HENRY TYLOR, of 28 and 30, East Road, City Road, in the County of Middlesex,
Venetian Blind Manufacturer. "AN IMPROVEMENT IN VENETIAN BLIND ACTIONS
AND THEIR HEAD LATHS."
This Invention relates to a certain improvement in Venetian blind actions, and in
their head laths to enable two or more raising and lowering cords to run over the
same clip or action, which is by my method enclosed or recessed in the head lath,
the clip or action being held in the head lath by the cross pin which is passed
through from the front or from the back.
The clipping bar, by my system, is formed by a cross pin also passed through the
head lath, and in position that the tongue of the clip bears towards it to bind the
cords between itself and the cross pin.

the said Henry Tylor in the Great Seal Patent Office on the 4th July 1881.
HENRY TYLOR, of 28 and 30, East Road, City Road, in the County of Middlesex,
Venetian Blind Manufacturer. "AN IMPROVEMENT IN VENETIAN BLIND ACTIONS
AND THEIR HEAD LATHS."
This Invention relates to a certain improvement in Venetian blind actions, and
in their head laths to enable two or more raising and lowering cords to run over
the same clip or "action," which is by my method enclosed or recessed in the head
lath, the clip or action being held in the head lath by a cross pin which is passed
through from the front or from the back. The clipping bar, by my system, is
formed by a cross pin also passed through the head lath, and in position that the
tongue of the clip bears towards it to bind the cords between itself and the
cross pin.
My Invention will be clearly understood by the annexed Sheet of Drawings.
Figure 1 is a plan view, and Figure 2, a side partly in section of my improved
head lath with an action fitted therein. A is the tongue pivotted on the pin B ;
C is a stop pin towards which the tongue presses to nip the cords D, D; E is a
roller fitted in the tongue, and F is a cross bar for the attachment of a short length
of wire G to the lower end of which a pull cord H is fastened. The roller E may
be of any desired width so that any number of lath supporting cords D, D, may be
run over it and be acted upon simultaneously.
In the Drawing I have shown three of such cords, these being led through
eyelets I, I, I, to keep them apart and to prevent one lapping over the other.
These three cords pass over the usual guide rollers J, J, J, to the bottom or foot
'lath of the blind in a manner well known.
Figure 3 is a part sectional view of the head lath with the tongue A in the
position it occupies when the pull cords D, D, D, are being acted upon to draw up
the blind, the view also shows it in the position it occupies when the releasing
cord H is being acted upon to allow the blind to close or be let down. Figure 4
shows the tongue as nipping the cords D, D, D, against the stop pin C.
Figure 5 is a detached perspective view of one of my improved action.
It will be observed by my Invention that I dispense with a base plate or bracket,
and instead of fitting my action on the head lath I fit it in it. I also dispense with
side plates or boxes for carrying the action by supporting it upon a pin passed
through from one side of the head lath, the stop pin being fitted in the head lath
in a similar manner, thus ensuring simplicity in construction, a reduction in weight,
and also in cost, and keeping the working parts within the thickness of the head
lath itself.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim,-
Arranging or fitting the head lath of a Venetian blind with an "action" within
it, and arranging the pull cords to run on one roller and be nipped by one
tongue common to all, as shown in the annexed Drawings and as herein before
described.
In witness whereof, I, the said Henry Tylor, have hereunto set my hand and
seal; this Fourth day of July, in the year of our Lord One thousand eight
