Improved Methods of Attaching Weight Cords to Window Sashes.
and the Apparatus therefor.
We WILLIAM BIRDTHISTLE Swanley House, High Road, Lower Clapton,
London, N.E. Upholsterer, and WILLIAM LUTWYCHE, of 19 Goulton Road,
Lower Clapton, London, N.E. Stained Glass Manufacturer, do hereby declare the
nature of this invention to be as follows:-
In carrying out my invention I make a cavity or socket on each side of the sash
and near the bottom of the cavity I place a hook. I take a thin strip of metal a
little less in length then the depth of the cavity and hinged at the top; this hinge.
is let into and is fastened on to the top of the sash and the longer portion is placed
in the socket on the glass side of the socket. This piece which I call the inner
piece is furnished with slots. Another similar piece of metal without the hinge but.
with studs to fit into the aforementioned slots is also placed in the socket. This
outer piece at its lower end has a slot which is passed over the hook in the cavity.
The cord is secured in any desirable manner to this outer piece in the socket.
When the inner piece is screwed on to the sash and the outer piece is passed over
the hook a secure attachment is made. To detach the contrivance from the sash I
unfasten the hinge and press the inner piece down. By this means the outer piece
is removed from the hook and the whole apparatus can be withdrawn.
In a modification of my invention the inner piece is not hinged but angled at the
top, and has at the bottom a stud projecting outwards. The outer piece of metal
has two movable jaws at the bottom between which the aforesaid projecting stud
works. Catches are placed at the bottom of the groove into which the outer edges
of the jaws fit when pressed outwards by stud. This is effected by screwing the.
angle piece to the top of the sash and pulling up the inner piece by the cord.
To remove this apparatus it is only necessary to unscrew the angle portion and
raise the inner piece. The stud then moves upwards and the jaws of the outer.
piece are liberated from their catches and all the apparatus can be removed from
the sash.

Improved Methods of Attaching Weight Cords to Window Sashes.
and the Apparatus therefor.
We, WILLIAM BIRDTHISTLE, Swanley House, High Road, Lower Clapton,
London, N.E., Upholsterer, and WILLIAM LUTWYCHE of 19, Goulton Road,
Lower Clapton, London, N.E., Stained Glass Manufacturer, 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 :-
To show clearly how our invention is carried out we furnish drawings in which
the same parts are represented by the same letters.
Fig. 1 is a front elevation of the apparatus attached to sash frame.
Fig. 2 is a side elevation of same.
The socket or cavity B is made in sash frame A in which is inserted an inner.
piece C hinged at D and the top part of it secured at E to the upper part of sash
frame A. C is furnished with slots F. F. An outer piece C¹ has on the back two.

page_text: studs J. J. working in the slots F. F. H is the contrivance for holding the sash
cord, and is no part of our invention. The lower portion of outer piece C¹ is
furnished with a slot K, into which is inserted a curved piece L, which said curved
piece is attached to the sash frame at M. In order to remove the apparatus from
the sash frame, it is only necessary to unscrew the top portion of C and push this
inner piece C downwards. This action pushes the outer piece C' free from L and
the whole apparatus can be taken out.
Fig. 3. shows in side elevation a modified form of the apparatus.
In this form the inner piece C extends below the outer piece C' and a stud N is
fixed near the bottom end of C projecting outwards. The outer piece C¹ carries
two jaws O. O. pivoted at R. R. and moving freely outwards and inwards. P. is a
cradle attached to the bottom of the socket in the sash frame shaped as shown to
receive the lower portion of the jaws. To secure the apparatus the inner piece C
is pushed downwards and its upper hinged part fastened to sash frame. The stud N
then forces out the jaws O, and the tension of the sash cord keeps the apparatus
fast. To release it the inner piece C is pulled up so that the stud N goes into the
wider space S between the jaws O. The jaws then come closer together and can be
withdrawn from cradle P.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
1. The inner piece C furnished with slots F in which work studs J of an outer
piece C, which outer piece is attached to fixed hook L in sash frame substantially
às described and shown in Figs. 1 and 2. for the purpose specified.
2. The modification as shown in Fig. 3. in which the inner piece C is furnished
with a stud N working between two jaws O attached to outer piece C¹, the jaws O
moving in fixed cradle P, substantially as described for the purpose specified.
