1. CHARLES SHAKESHAFT, formerly of 10 Harvey Street, Hyde Road, but now
of 42, Felton Street, Hoxton, in the County of London, Carpenter, 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 :-
In sliding window sashes as at present constructed the grooves in which the
supporting cords are placed, are carried down only a short distance. Now in this
invention I carry the grooves right down the sides of the sash, and in the case of
the lower sash this groove is continued, either across the whole length of the
underside of the bottom rail or a portion of that distance, for a purpose to be
hereinafter described.
In the upper sash the grooves run in the sides and two small brackets are
screwed on to the bottom rail.
In order that my invention may be most fully understood and ascertained, L
have appended drawings in which :-
--
Fig. 1. is a perspective view of an upper sash.
Fig. 2. is a perspective view of a lower sash.
Fig. 3. is a perspective view of one of the brackets as used with the upper sash.
In the lower sash, as shown in Fig. 2. the sides B as well as the bottom rail G
have a groove b formed along their whole length on the outside. It is essential
to the invention that the groove shall be carried the whole length of the sides,
but it need not be carried along the whole length of the bottom rail, if it is cut
in about 2 or 3 inches from each side it is sufficient. In that part of the frame
which forms a slide or guide for the sash, a pocket piece or shutter opening is
cut, through which the weight and its attached cord is accessible, and through
which the weight can be inserted or removed.
In sashes as at present constructed when a weight has to be removed or a new
cord inserted it is necessary to remove the sash from the frame and also to detach
a port on of the beadwork.
Now in a sash constructed according to my invention
a new cord can be inserted without removing either sash or beadwork. A cord
is cut to the right length and one end is pushed into the space above the cord
[ Prine H.27

can be grasped by the hand and withdrawn, after attaching it to the sash weight,
the latter is placed in position through the opening. The other end of the cord can
then be threaded through the groove b until it reaches the bottom rail. The window
sash being then raised the end can be fastened in any convenient manner in the
groove in the bottom rail.
In the case of the upper sash shown in Fig. 1 the same course is followed, the cord
being threaded down the groove a in the side A until its end projects, and it is then
grasped by the hand and passed through a hole d in the bracket D. This is done
before the bracket D is placed in position; the end of the cord is then tied into a knot
large enough to prevent its passing back through the hole d. Then the bracket D is
placed in position and secured to the sash by means of screws C or other equivalent
fastening. The bracket D is recessed at d' below the hole d in such manner that the
knotted end of the cord is contained therein.
It will be seen that the principle feature of my invention is the grooving of the
frame sides, by means of which, the weights being accessible through openings in the
frame, a new cord can be inserted, or an old one taken out without removing either
the sashes or beadwork.
In some cases holes may be bored or tubes inserted in place of the grooves.
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 is :
1. A window sash having its sides grooved in such a manner that the cords can be
threaded down it, so as to enable a cord to be taken out or replaced without taking
out the sashes or any portion of the frame, substantially a shown and described.
2. A window sash having grooves in its sides, and a groove along the whole
or part of its bottom rail, substantially as shown and described with reference to
Fig. 2.
3. A window sash having grooves in its sides, substantially as shown and described
with to Fig. 1.
4. The bracket substantially as shown and described with reference to Fig. 3.
5. A window having grooves in its sides, and brackets attached to its meeting rail,
aubstantially as shown and described with reference to Fig. 1.
