Improvements in Fasteners for Sash Cords of Windows, and in
Appliances employed in the Manufacture of such Fasteners.
1, JOHN WILLIAM MUMBY of 7 Green Mount Terrace, Hanson Lane, Halifax
in the County of York, Cabinet Maker, do hereby declare the nature of this
invention to be as follows :-
This invention relates to improved method of, and appliances employed for
securing the sash cords of windows to the sash bars, or frames of such windows and
also to improvements in the construction of moulds employed in the manufacture of
such appliances for purpose aforesaid.
According to this my invention the appliance for securing the sash cord consists
of two lugs or ears, cast to and forming part of a bracket, mounted between the
lugs or ears, and carried eccentrically on a through pin is a swing catch the outer
edge of which is grooved, and serrated for the purpose of holding the cord which
when threaded between the lugs and the serrated catch and the cord pulled in the
other direction is pinched and held firmly by the eccentric swing catch. The
fastener is fixed by screws in a recess formed in the sash bar of the window, and
the sash cord is received in the ordinary groove for that purpose, and to secure the
cord, the fastener only is to be removed, the cord threaded down the groove, until
the end is opposite the recess or hole for the fastener, the end of the cord is then
drawn through this hole, and threaded through the fastener as above described,
the fastener is then replaced and fixed in position in the recess so that it will be
seen sash cords can be attached to windows and secured in position without removal
of the "sash bars
parting sash"
as was heretofore necessary.
دو
The improved mould for casting the lugs and bracket of the fastener is
constructed that several may be cast at one operation, the mould being formed in
three parts the two outer ones forming the box, and the inner one the core, having
recesses on each side of it of size and shape of the lugs or cars, and a continuous
recess along its edge forms the brackets, which are to be divided afterwards. The
core is placed in a recess in the box and the latter is held or clamped together by
eccentric handle or clamp.
The mould for forming the swing catches has a double core, or a core divided
into two parts in order to form the grooves and serrations in the castings and to
facilitate the stripping. The box is clamped together by eccentric handles or
clamps.
The boxes have troughs formed in them into which the molten metal is run and
a series of holes in such troughs communicate with the interior of the boxes and
the cores.

Improvements in Fasteners for Sash Cords of Windows, and in
Appliances employed in the Manufacture of such Fasteners.
I JOHN WILLIAM MUMBY of 7 Green Mount Terrace, Hanson Lane, Halifax
in the County of York, Cabinet Maker 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 :-
This invention relates to improved method of, and means, and appliances

page_text: employed for securing the sash cords of windows to the sash style, or bars, or
frames of such windows, and also to improvements in the construction of moulds
employed in the manufacture of such appliances for purpose aforesaid.
According to this my invention the appliance for securing the sash cord consists
of two lugs, or cars, cast to and forming part of a bracket; mounted between the
lugs, or ears, and carried eccentrically on a through pin is a swing catch the outer
edge of which is grooved, and serrated for the purpose of holding the cord when
threaded between the lugs, and the serrated cateli..
The improved mould for casting the above described fastener is constructed that
several may be cast at one time, the mould being formed in three parts, the two
outer ones forming the box, and the inner one the core having recesses on each side
of. it of size, and shape of the lugs, or cars, and a continuous recess along its edge
forms the brackets which are to be divided afterwards. The core is placed in a
recess in the box, and the latter is held or clamped together ly eccentric handle, or
clamp.
The mould for forming the swing catches has a double core, or a core divided
into two parts in order to form the serrated grooves, and to facilitate "stripping"
of the castings.
The boxes have troughs formed in them into which the molten metal is run, and
a series of holes in such troughs communicate with the interior of the boxes, and
the cores.
Such being the nature, and object of my said invention the following is a
complete description of same reference being made to the accompanying drawings
in which
Fig. 1 is a side elevation of my improved fastener, or holder for sash cords of
windows, shewing part of a sash style in section, and the mortice cut therein.
Fig. 2 is a front elevation of Fig. 1.
Fig. 3. is a similar view to Fig. 1. but shewing one of the lugs, or ears removed
in order to shew the eccentric swing catch more distinctly, the woodwork is also
removed.

Fig. 5 is an end view of the eccentric swing catch shewing the serrated, or
toothed groove.

lugs, or cars, and brackets the front part of the box being removed in order to shew
the interior.

Fig. 12 is an end sectional view of the core of the mould..
According to this my said invention the appliance for securing the sash cord 1
consists of two lugs, or cars 2. 2. cast to, and forming part of a bracket 3; mounted
between the lugs or cars 2. 2. and carried eccentrically on a through pin 4 is a
swing catch 5, the outer edge 6 of which is grooved, and serrated (see Fig. 5.) for
the purpose of holding the cord 1 which is threaded between the lugs, or ears 2. 2.
and the serrated edge 6 of the catch 5, and when the cord 1 is pulled in the other,
or reverse direction as shewn by the arrow in Fig. 1. as is always the case when the
weight is applied to the other end of the cord 1, the latter is pinched or nipped, and
held firmly by, and between the eccentric swing catch 5 and the back 3.
fastener is held in a recess or mortice 7" formed in the ordinary sash style 16 of the
window, and the sash cord 1 is received in the ordinary groove 9 for that purpose,
and to secure the cord the fastener only is to be removed from its recess or
mortice 7, the cord threaded down the groove 9* until the end is opposite the recess,

or mortice 7 for the fastener, the end of the cord is then drawn through this
recess, or mortice 7", and threaded through the fastener as above described, the
fastener is then replaced in position in the recess or mortice 7* the ends 3° 3° of the
back 3 resting on the face of the sash style 16 and it will be seen that by the use of
my improved fastener sash cords can be attached to windows, and secured in position
without removal of the "sashs," or "beads" as was heretofore necessary.
The fastener may be secured to the sash style 16 by the use of screws, if thought.

The improved mould for casting the lugs, or cars 2. 2. and brackets 3 of the
fastener is constructed that several may be cast at one operation, the mould being.
formed in three parts, the two outer ones 8,.9, forming the box, and the inner
one 10 the core, having recesses 11. 11. on each side of it, of size, and shape of
the lugs, or cars 2. 2, and a continuous recess 12 along the edge forms the
brackets 3 which are to be divided after removal from the box, and to facilitate
this small angular projections 20 are formed on the box 9 so that indents are made
in the casting formed by the long recess 12, and the casting when removed from

is placed in a recess 13 in the box 9 and the part 8 of the box is held, or clamped
to the part 9 by eccentric handle or clamp 14.
The mould for forming the swing catches 5 is similar to the above but has a
double core 15. 16 or a core divided into two parts 15. 16 in order to form the
grooves 6 and serrations in the castings 5 and to facilitate the "stripping." The
box is held together by eccentric handles, or clamps 14.
The boxes have troughs 16 formed in them into which the molten metal is run,
and a series of holes 17" in such troughs 16" communicate with the interior of the
boxes, and the cores.
Having now particularly described, and ascertained the nature, and object of
my said invention, and in what manner the same is to be performed 1 declare
that what I claim is :-
1. The fastener comprising the nipping parts 5. 6. side guides 2. 2. and plate 3
applied in manner to, and in combination with a sash "style" of a window, so as to
admit of renewal of cords, without removal of the sashs, or beads.
2. The combination of parts constituting the improved appliances or moulds as
shewn by Sheets 2 and 3 of the accompanying drawings.
