I, GEORGE RIDLEY, of 43, Claughton Firs, Claughton, in the County of Chester,
Master Builder, do hereby declare the nature of this invention to be as follows.-
When it is required to put a new cord into a window sash it is requisite to take
the entire sash out of the frame in order to nail the cord to the sash in the ordinary
groove. This entails taking strips off the window frame and always leaves ugly
marks behind besides involving a very considerable amount of labor.
This invention is designed to at any time take out a cord and put in a fresh one
without in any way requiring the sash to be taken out of the frame or even to be

sash frame as near the glass as practicable and on the inside I cut out a slot with a
curved bottom sloping up to the groove and in this slot fix a roughened pawl, friction
lever or eccentric pivotted to a brass or other bracket let into the sash. To introduce
a new cord, the cord is pushed down the groove and the end comes out at the slot.
The pawl or eccentric is then turned so as to bite the cord tight. A screw, wedge or
other mechanism is then forced against the lever or eccentric if desirable so as to
lock it in place. The more strain there is on the cord, the tighter the cord draws
eccentric or friction lever.
When the cord has been adjusted the end is cut off, the lid or cover replaced on
the slot and nothing can be seen but a neat looking brass plate. If the cord breaks,
the screw or wedge is loosened, the lever pulled back and the cord is now loose and
can be pulled out and another substituted.
This mode of attachment of cords is applicable for other frames raised and lowered
by cords where the attachment of the cord is required to be concealed.

I, GEORGE RIDLEY of 43, Claughton Firs, Claughton, in the County of Chester,
Master Builder, 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 :-
When it is required to put a cord into a window sash it is necessary to take the
entire sash out of the frame in order to nail the cord to the sash in the ordinary
groove. This entails taking strips off the window frame, and always leaves ugly
marks behind besides involving a very considerable amount of labour.
This invention is designed to enable one at any time to take out or put in a cord
without requiring the sash to be taken out of the frame or even to be moved outwards
in any way.
Referring to the accompanying drawings which show my experimental apparatus :-
Figure 1 is an elevation of part of a window frame and sash, portions of the same
being broken away.
Figure 2 is a section on line a b, Figure 1.
Figure 3 is a section on line cd, Figure 1.
Like letters refer to corresponding parts in all the Figures.
A is the frame of the window which is provided with the usual strips a, with the
ubject of preventing side play of the sashes B.
In the inner face of the sash frame B, as near the glass 6' as practicable, a slot (
18 cut or otherwise formed with a curved bottom sloping up to the ordinary groove b³.
In this slot C is a friction lever, eccentric or roughened pawl C, as shown, which is
pivoted in a brass or other bracket or frame D, placed securely in the slot C.
To introduce a cord, the cord E is pushed down the groove 6' and the end comes
out at the slot C The pawl C or eccentric is then turned so as to bite the cord E
tightly against the bottom of the slot C. A screw D¹, wedge or other mechanism is
then, if desirable, forced against the pawl (" (or its equivalent) so as to lock it in.
place. The more strain there is on the cord, the tighter the cord draws the pawl
eccentric or friction lever (.
When the cord has been adjusted, the end may be cut off and a lid or cover F
placed on the slot, which thus presents no objectionable appearance. If the cord
breaks, the screw D₁ or wedge is loosened, the pawl C¹ pulled back, and the cord is
now loose and can be pulled out, and another substituted.
The other side of the sash is provided with a similar appliance.
The other end of each cord may be fastened to the counterweight in the usual
manner, that is, by pushing the cord over the pulley and down the space behind,
until it reaches the opening which is usually made in the side of the frame, for the
purpose. The cord may then be tied to the weight. The opening is normally..
covered by a strip of wood or equivalent.
This mode of attachment of cords is applicable for other flames raised and lowered
by cords where the attachment of the cord is required to be concealed.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim 18:
1. The improved method of attaching a suspension cord to a window sash or the
like, which consists in passing the end of the cord down the ordinary cord groove
into a slot or recess opening on to the exterior or visible portion of the sash, and in
securing it within said recess by means of a self-tightening clamping device, such as
described, manipulated from such exterior portion of the sash, whereby a cord can
be readily attached, removed, or adjusted without withdrawing the sash from its
frame.
2. The improved device for attaching a suspension cord to a window sash or the
like, consisting essentially of a slot or recess in the sash communicating on the one
hand with the exterior or visible portion of the sash, and on the other hand with the
ordinary cord groove therein, of a self tightening friction lever or its equivalent
mounted eccentrically within said recess, and adapted to press the cord against the
preferably curved bottom of the same, and of an adjustable pressure device manipu-
lated from the exterior of the recess and adapted to effect the clamping of the cord
by the lever in the first instance, substantially as and for the purpose set forth.
3. The improved attachment for the suspension cords of window sashes or the
like, constructed as a whole, substantially as described and shown in the accompanying
drawing.
