EASY APPLICATION OF NEW SASH CORDS TO WINDOWS
Year: 1885

page_text: WEST MUSSELWHITE, and WILLIAM PREWETT, trading as Musselwhite and
Prewett, Cabinet-makers, St. Michaels Rise, Bournemouth do hereby declare the
nature of their invention for THE EASY APPLICATION OF NEW SASH CORDS TO
WINDOWS, to be as follows:-
The invention consists of an iron socket, and a grip, or small pair of jaws for
holding the sash cord. On the inside, or concave, surface of these jaws are three
pointed teeth, two in one jaw and one in the other.-When closed, the grip forms
a taper, the base of which is slightly larger than the bore of the socket; the
form and construction, and the manner of application is shown in the attached
Drawings.
Figure 1 shows the size and shape of the piece of sheet metal from which the
socket is made, (marked A).
Figure 2 shows the brass head or flange marked B.
Figure 3, shows the grip, (C) with jaws open.
Figure 4, shows the finished socket, (composed of parts A and B) with grip C
closed and placed in position; the holes D. D. are for fixing the socket in window
sash, as shown in figures 5 and 6.
Figure 5 is a back section, showing the manner in which the parts A and B are
put together with rivets E. E. E. and secured in window sash (F) by an ordinary
round headed screw (G).
Figure 6 is a side section, showing the socket as fixed in window sash, (F) The
sash cord (H) is shown in the position in which it is held by the grip jaws C.
It is proposed to manufacture the socket (A) of rolled sheet iron, and the
head (B) and grip jaws C of cast brass, but the parts may be made of any other
metal or material which circumstances may render necessary or advisable.
The drawings are full size for a medium sized socket, but it may be made either
larger or smaller, to suit windows of various sizes.
The only alteration necessary in the woodwork of the window is, that the piece
of board, (called by joiners "the pocket piece" must be made to fit between the
beads of the window frame, and fixed with a small screw, instead of being over-
lapped by the beads in the usual manner; so that it may be removed for the
purpose of attaching the cord to the sash weight without removing the beads.

page_text: We are aware that other devices are before the public, for attaching new sash
cords without removing the window from its place; but the improvements in our
invention, on which we base our application for protection are-
1st. Our socket and grip will hold either twisted or woven cords without
slipping.
2nd. As the cord is held by the smooth inside surface of the grip, and not by the
teeth alone the cord is not cut or torn.
3rd. The heavier the strain put on the cord the more tightly the grip will hold.
These advantages, we believe, are not possessed by any invention except our
socket and grip, (shown in its complete form in Figure 4 of the attached Drawings)
and for this invention we humbly pray that a patent may be granted to us.

page_text: WEST MUSSELWHITE, and WILLIAM PREWETT, trading as Musselwhite and
Prewett, Cabinet Makers, St Michaels Rise, Bournemouth, in the County of
Hants, do hereby declare the nature of their invention for AN IMPROVED
SOCKET, OR HOLDER, FOR THE LINES OR CORDS OF WINDOWS 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 invention is to provide a ready means of Attaching Sash Cords
to Windows, without removing the sash from its place, and also form a strong
metal clip which will strengthen the sash at its weakest part.
The invention consists of a strip of brass or other metal, which is inserted
vertically in a groove at the side edge of the window sash; at the top is a plate,
set at right angles, having a hole for screwing the same to the top rail or bar of
the window, another hole is provided at the lower extremity to receive a screw
passed through the side of the sash; attached to this strip of metal, on its front
edge, is a tapered socket, the smallest part upwards, inside which is inserted, from
the under side, a small pair of jaws, (called the grip) for holding the sash cord;
these jaws are jointed, to admit of their being opened and closed on their inside or
concave surface are three small teeth, two in one jaw and one in the other; when
closed the grip forms a taper, the base of which is slightly larger than the bore of
the socket.
To fit our socket to an existing window the only alterations necessary to the
wood-work are-the groove already in the edge of the sash must be enlarged to
sufficient width and depth to receive the socket, and the piece of board called by
joiners the "pocket piece" must be made to fit between the beads of the window
frame, instead of being over-lapped by them in the usual manner; so that it may
be removed for the purpose of attaching the cord to the sash weight without
disturbing the beads; if the pocket piece should fit too loosely to remain in its
place it can be fixed with a small screw.
To fit a new cord to a window which is furnished with our sockets, first pass a
small weight, with string attached, over the axle pulley of the window in the
usual way, then slide up the sash and remove the pocket piece, draw the new cord
over the pulley by means of the string, fasten it to the sash weight, and re-place
the pocket piece; next, slide the sash down, and pull the cord until the weight is
as high as it will go, and cut the cord to the required length, (it is a good plan to
drive a small peg of hard wood into the hole in pulley, to hold up the weight until
the operation is completed) now withdraw the two screws, and take out the socket,
it can usually be withdrawn by the end of the broken cord, if it fits tightly insert
a screw driver under the top plate and gently force it out, remove the old cord,
pass the new one through the socket, and close the grip jaws on the end of it,
re-place the grip in socket as tightly as possible, return the socket to its place and
fix with screws.
If the sockets are used for wire cords, or chains, the grip jaws are not required,
the end of the cord or chain is simply made off in the usual way, care being taken

page_text: that the knot is not farger than the base of the socket, and sumciently large to
prevent its being drawn quite through.
We are aware that other devices are before the public for holding sash cords,
also for attaching new cords without removing the window sash from its place;
we make no claim which in any way interferes with the rights of the patentees of
these inventions, the improvements we claim for our invention and the advantages
gained by its use are,―
1st. Our socket, from the fact of its being securely fastened to the upright part
of the sash, and also to the top rail, acts as a strong corner clip, whereby the sash
is considerably strengthened at the weakest point of its construction.
2nd. Our socket and grip will hold either twisted or woven cords without
slipping and the heavier the strain put on the cord the more tightly the grip
will hold.
3rd. As the cord is held by the smooth inside surface of the grip, and not by the
teeth alone, there is no tendency to cut the cord.
That the form, and manner of application of our invention may be more fully
understood we now describe it by reference to the accompanying drawings.
DESCRIPTION OF THE DRAWINGS.

piece of brass or other metal, D is the grip with jaws closed and placed inside
socket, jis the joint pin or rivet on which the jaws work; h. h. are the screw
holes for fixing to sash.

Fig. 3. shows the grip with jaws open. t. t. t. are small spikes or teeth.
Fig. 4. is part of an ordinary window sash. E is the top rail. F is the upright
side of sash. 7. r. is the recess which must be cut to receive the socket, m. m. are

Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is,-
An improved sash line socket or holder, in the construction of which, provision
is made to admit of its being fixed to both top and side of the window sash, and
also having a grip, or pair of jaws, with teeth, for holding the sash cord.
