Sliding Sash Frames of Windows
I, WITAM NICOL of 55 Albert Road, Crosshill, in the City and County of
Glasgow, Joiner, do hereby declare the nature of my invention to be s
follows
This invention nas reference to improvements in and relating to fastening>
connected with the sliding sash fiames of windows
Under one arrangement a plate would be screwed to the top rail of the lower
sliding sash fiame, and have a kneed on catch um formed over it
A recess would be formed in the fixed fiame of window opposite the position
of the catch plate where the sash frame is desired to be swivelled within the
apartment, and a slotted plate with or without one open end would be screwed over
this recess
A loose movable arm or organ would be fitted to carry the end of the
counterbalance weight cord, and be secured in position within the kneed catch
plate of sash fiame when the latter is in its normal sliding position but when the
window is to be swivelled within the apartment this movable arm would be swivelled
within the recess of fixed frame and so disengage the counterbalance weight cold
from the sash frame and enable the latter to be swivelled within the apartment
and when opened out the movable arm may be secured by a button or pin which
would enter a slot in aim or vice versa While the movable arm would be swivelled
out from the recess to engage with the catch plate of sash frame when the latter is
again placed in its sliding position The end of swivelling arm next the recess in
its engaging position with catch plate would preferably be curved or rounded for
Oscillating on and the opposite end be formed with a knob or pin for turning it by
haud and projecting guide be formed at the centre for being on the overbung
catch The knotted end of cord would be passed through a hole in movable arm
and a socket ferrule may be formed underneath to receive sime, and enter a recessed
socket in screwed plate of catch arm in the securing position The wood of sash
rail would be cut away or recessed at the part where the arm oscillates
the swivelling aim may be made to act automatically the opening out movement of
while
sash frame acting on the arm to swivel it within the recess of fixed fiame
the return movement of sash fiame would move the swivelling aim with cord int>
the locked position on sash rail
If desired
In regard to the upper sash frame when it is secured to a sliding rail or style,
a swivelling kneed um oi oigan would be secured either to the top or bottom of
this rul or style, and be swivelled within a recess or socket plate in sash fiume
when the latter is in its normal sliding position to secure the two together, but
when the sash frame is to be swivelled within the apartment the aim would be
Swivelled in the reverse direction to enter a recess in fixed fiame of window and
so disengage the style from sash frame and lock or secute the style to the fixel
frame until the sash frame is again swivelled back into position and the catch
arm swivelled back to engage with same The counterbalance cold would be
secured to sliding style
A slot may be formed in the sliding sash frame and a kneed plate be screwed to
the fixed frame so as to enter the slot when the sash frame is to be swivelled
within the apartment, or vice versa, and thus act as an auxiliary guide to the cord
detacher

page_text: By a modified arrangement the counterbalance cord or weight of the lower sash
frame would be passed through an eye or hole formed in the top kneed or flanged
end of a plate which would slide in a groove or on face of fixed frame and when
the sash frame is desired to be swivelled within the apartment pin or key would
be passed through a hole or slot formed in this plate and enter a corresponding
hole in a plate screwed to fixed frame, and so lock the cord plate in position, while
a double kneed or catch plate would be screwed to the top rail of lower sash to
hook or engage with a concave, recessed or kneed flange or pocket formed at
lower end of counterbalance cord plate and thus slide up and down with it, but
when the cord plate is locked, this kneed plate can be lifted out and the sash frame
swivelled within the apartment While when the sash fiame is again swivelled
back to the sliding position it will engage with the cord plate and the locking pin
can then be removed and preferably inserted in a hole in kneed plate of sash
frame
For the top sash frame a similar counterbal ince cord or chain plate would be
used preferably having a pocket chamber o recess with side or side and back
checks for the lower rail of to sash to rest in, and having back vertical rail
which would slide in a groove in fixed frame and to which the cord or chain would
be attached, or when no back check is used the cord could be attached to a hole
formed in a snug at top of plate
When the sash frame is to be swivelled within the apartment the counterbalance
cord plate would be portably locked by a key or pin entering a slot or recess
formed in its attaching plate and in a corresponding plate screwed to fixed

Improvements in and relating to Fastenings connected with the
Sliding Sash Frames of Windows
WILIAM NICOL, of 05 Albert Road, Crosshill, in the City and County
of Glasgow, Joiner, do hereby declare the nature of my invention, and in what
ninner the same is to be performed, to be particularly described and ascertained
n and by the following statement in writing that is to say
This invention has reference to improvements in and relating to fastenings
connected with the sliding sa h fiames of windows
Aud in order that my said invention and the manner of performing or carrying
same into practice may be properly understood, I have hereunto appended in
explanatory sheet of drawings in which
Figure 1 presents a detached elevation in per pective of the counter balance
cord holder as secured in a witch arm in the closed sliding position of the sìshes in
accordance with one airangement of my improvements
Figure 1 is detached view of the catch device shown in Figure 1
Figure 2 represents an elevation of the lower and upper sash frame, in which
the devices illustrated in Figure 1 are shown as applied in connection with the
lower sash when in its closed on sliding position, while Figure 3 represents a
similar view showing the sash fiame as detached from the counterbalance cord
holder
Figure 4 shows a modified arrangement of my improved devices as applied to
the upper sash frame
Figure 5 is a view similar to Figure 1 showing a modified airangement of my
devices and Figures 6 and 7 show views of details of same, while Figure 8 illustrates
these devices as applied in connection with the lower sash fiame

page_text: Figure 9 shows a view of a modified device as suitable for being applied in
connection with the upper sash, the latter application being illustrated in
Figure 8
Referring to these drawings
-
Under one arrangement as shown in Figures 1 to 3 a plate a would be screwed
to the top rail A¹ of the lower sliding sash frame A, and have a kneed or catch
arm a formed over it A recess would be formed in the fixed frame of window
opposite the position of the catch plate where the sash frame A is desired to be
swivelled within the apartment and a slotted plate c, c' would be screwed over this
recess A loose moveable arm or organ b would be fitted to carry the end of the
counterbalance weight chain or cord B, and be secured in position under or within
the kneed catch plate a a¹ of sash frame A, when the latter is in its normal sliding
but when the window is to be swivelled
position as shown in Figures 1 and 2
within the apartment this moveable arm 6 would be swivelled within the recess
plate cc of fixed frame and so disengage the counterbalance weight cord B from
the sash frame A and enable the latter to be swivelled within the apartment as in
the position shown in Figure 3 and when opened out the moveable arm in
addition to entering the slotted plate e c¹ may be further secured by a swivelling
and instead of
button or pin 2 which would enter a slot 63 in arm b¹, or vice versa
C
a button a spring catch may be used while the moveable arm would be swivelled
out from the recessed plate c, c¹ to engage with the catch plate a, a' of sash
frame A when the latter is again placed in its sliding position as shown in
Figures 1 and 2
The
The end of swivelling arm b next the recess in its engaging position with catch
plate a would preferably be curved or rounded for oscillating on, and the opposite
end be formed with a knob or pin 6 for turning it by hand, and a projecting
guide be formed at the centie for bearing on the overhung catch al
knotted end of cold B would be passed through a hole in moveable arm 6 and a
socket ferrule 66 may be formed underneath to receive same, and enter a recessed
The swivelling
socket a² in screwed plate of catch arm a in the securing position
arm would be made to act automatically as shown under one construction in
Figure 1B
In this arrangement a projecting piece 612 and a slotted or recessed
part 618 is formed on the moving arm b, and a projecting piece a³ is formed on the
By this means in the opening out movement of sash frame A the
projection a³ acts on slotted part 613 of aim band so automatically swivels the latter
within the recess c c¹ of fixed frame A4, while in the return movement of sash
frame A the plate a acts on the projecting part 612 and the projection a³ acts in the
slot 13 and by this means the swivelling arm is automatically moved with coid
into the locked position on sash rail The projections guide the arm b in its
travelling movements
arm a
In regard to the upper sash fiame A² when it is secured to a sliding rail or
style A as shown in Figure 4, a swivelling kneed arm or organ 6 would be
mounted to swivel on a pin 610 at the top or bottom of this rail or style A³ and be
Swivelled within a slotted or socket plate a a¹ in sash frame A² when the latter is
in its normal sliding position to secure the two together, but when the sa-h
frame A is to be swivelled within the apartment the arm b would be swivelled in
the reverse direction to enter a recess in fixed flame A' of window and so
disengage the style A³ from sash frame A² and lock on secure the style A³ to the
fixed frame A until the sash frame A2 is again swivelled back into position and
the catch arm b swivelled back to engage with same Ihe counterbalance cord B
would be scoured to sliding style
A slot may be formed in the lower sliding sash frame A and a hneed plate f
be screwed to the fixed frame so as to enter the slot f when the sash frame A is to
be sw velled within the apartment, or vice versa, and thus act as an auxiliary guide
to the cord detacher
By a modified arrangement as shown in Figures 5 to 8 the counterbalance cord
o weight B of the lower sash frame A would be passed through an eye or hole

page_text: formed in the top kneed or flanged end 61 of a plate 6 which would slide in a
groove or on face of fixed frame A and when the sash frame A is desired to be
Swivelled within the apartment a pin or key e would be passed through a hole or
slot 63 formed in this plate b and enter a coi responding hole e' in a plate c screwed
to fixed frame A', and so lock the cord plate b in position, while a double kneed of
catch plate a a' would be screwed to the top rul A¹ of lower sash A to hook or
engage with a concave recessed or kneed flange or a pocket 6 formed at lower end
of counterbalance cord plate band thus slide up and down with it, but when the
cord plate bis locked, this kneed plate a a¹ can be lifted out as shown in Figure 8
and the sa h frame A swivelled within the apartment While when the sash
frame A is again swiselled back to the sliding position it will engage with the cord
plate band the locking pin can then be removed and preferably inserted through
holes a* in the kneed plates a b as shown in Figure 8 Instead of the part a¹
sliding on or off the part of plate bit may be made to act with a lift off
movement In the rangement shown in Figure 5A a slot 614 is formed in the
moveable arm band a projecting piece a on catch plate a so that in swivelling out
the sash frame the latter has to be slightly raised Figure 5B shows a similar
arrangement in which the sash has to be slightly raised before being swivelled out
Figure 5 shows an arrangement in which plate 2 is substituted for the devices
shown in Figures 6 and 7 An aim ³ of a straight or curved shape works through
a slot in the plate c² secured to fixed frame A, and the arm c³ on being diawn out
by hand or pressed out by a spring, holds the aim with the cord B in position
while the sash frame A. is swivelled out Figure 5 shows a similar arrangement
in which the arm ³ is made to swivel automatically or by a spring hinge and be
operated by a cord or by the movement of the batten rod
For the top sash frame A2 a similar counter balance cord or chain plate would
be used as shown in Figure 9 preferably having a pocket chamber or recess 67 with
side cheeks 68 01 it may be side and back cheeks for the lower il A³ of top
sash A² to rest in as shown in the lower part of Figure 8 and having a back
vertical ail 6° which would slide in a groove in fixed fiame A and to which the
cord or chain B would be attached, or when no back cheek is used the cold could
be attached to a hole formed in a snug at top of plate
When the a h fiame A2 is to be wiselled within the apartment the counter
balance cold plate / would be portably locked by a 1 ex or pin e cntering a slot of
recess formed in its attaching plate and in a cone ponding plate screwed to
fixed frame A'
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
