PROVISIONAL SPECIFICATION.
Improvements in and relating to Window Sash and Batten Rod
Fasteners.
I, WILLIAM NICOL of 55 Albert Road, Crosshill, in the County of the City
of Glasgow, Joiner, do hereby declare the nature of my invention to be as
follows:-
This invention has reference to an improved method and devices for preventing
burglars or others from the outside raising the lower sliding sash or lowering the
upper sash of windows, said devices also acting as fasteners for keeping the hinged
batten rods in closed position.
The improvements consist in fitting a loose swivelling arm on the face of the
lower sash frame, being preferably secured to the latter by a screwed plate and
central stud pin.
This swivelling arm would preferably be formed of a kneed or crank shape
mounted on the stud pin at its inner end and having a deep flange projecting out at
right angles at its outer end.
A double kneed plate would be screwed into a recess in the batten rod opposite
the aforesaid swivelling arm in the closed position of the sash.
In sliding the sash from the inside of the apartment the flange of kneed arm would
bear on the batten rod, but when its upper end descended below the line of plate
screwed into recess in batten rod it would drop into same, and if the window
was attempted to be raised from the outside the top of swivelling arm would
come against the kneed part of batten rod plate and prevent the lower sash being
lifted.
Similarly for the upper sash the lower end of swivelling arm would bear on
the kneed part of batten rod plate and prevent the upper sash being drawn
down.
When the sashes are desired to be swivelled within the apartment for cleaning
purposes the arm of fastener would be swivelled outwards so as to free the batten
rods and enable them to swivel outwards on their hinges clear of the sash frames.
In their outer and in their inner positions the swivelling arms may be locked by
stop or locking pins, or by sliding eccentric, spring acting or equivalent catches,
entering adjustable notches in arm.
If desired a recoil acting spring may be mounted in connection with swivelling
arm.
When wind and water tight hook plates are fitted on the sides of sliding sash
frames and fixed frames of windows the swivelling arm may have a pin or projection
formed on it, to pass through slots or holes in these plates and so lock or secure the
sash frame in position.
Two of these fastening devices may be mounted on each sash frame at distances
from each other so as to admit when desired of raising the lower sash or lowering
the upper sash a predetermined distance for ventilating purposes.

Fasteners.
I, WILLIAM NICOL, of 55 Albert Road, Crosshill, in the County of the City of
Glasgow, Joiner, do hereby declare the nature of my invention, and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement in writing, that is to say :-
This invention has reference to an improved method and devices for preventing
burglars, or others from the outside, raising the lower sliding sash or lowering the
upper sash of windows, said devices also acting as fasteners for keeping the hinged
batten rods in closed position.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood I have hereunto
appended an explanatory sheet of drawings in which Figure 1 is a sectional
elevation showing the lower sliding sash frame of window as locked by one of
my fasteners, and Figure 2 is a horizontal section corresponding to Figure 1.
Figure 3 is a view similar to Figure 1 showing the upper sash frame as locked
in position. Figure 4 is a similar view showing the locking fastener as applied
when weatherproof plates are applied to the sash frames; and Figure 5 is a
horizontal section shewing these plates in position.
Referring to these drawings:-The improvements consist in fitting a loose
swivelling arm A. on the face of the lower sliding sash frame B being preferably
secured to the latter by a screwed on plate A³ and central stud pin A'.
This swivelling arm A would preferably be formed of a kneed or crank shape
n.ounted on the stud pin A' at its inner end, and having a deep flange A² projecting
out at right angles at its outer end.
A double kneed plate C' would be screwed into a recess in the batten rod C
opposite the aforesaid swivelling arm A in the closed position of the sash B.
In sliding the sash B from the inside of the apartinent, the flange A² of kneed
arm A would bear on the batten rod C, but when its upper end descended below
the line of kneed part C² of plate C₁ screwed into recess in batten rod C it would
drop into same, and if the window was attempted to be raised from the outside
the top of swivelling arm A would come against the kneed part C² of batten
rod plate C¹ and prevent the lower sash B being lifted.
Similarly for the upper sash B' the lower end of swivelling arm A would bear
on the kneed part C² of batten rod plate Cand prevent the upper sash B' being
drawn down.
When the sashes are desired to be swivelled within the apartment for cleaning
purposes the arm A of fastener would be swivelled outwards so as to free the
batten rods C and enable them to swivel outwards on hinges C³ clear of the sash
frames B, B¹. In their inner and in their outer positions the swivelling arms A
may be locked by stop or locking portable pins a attached to chains a¹ and inserted
in position holes in sliding sash, or other equivalent locking or retaining catches
may be used.
If desired recoil acting springs may be mounted in connection with the swivelling
arms A.
When wind and water tight hook plates bbb are fitted on the sides of sliding
sash frames B B' and fixed frames of windows, as shown in Figures 4 and 5, the
swivelling arm A. may have a pin or projection A" formed on it, to pass through
slots or holes at 3 in these plates bbb and so lock or secure the sash frames in
position.

page_text: Two of these fastening devices A may be mounted on each sash frame B B' at
distances from each other so as to admit when desired of raising the lower sash B
or lowering the upper sash B' a predetermined distance for ventilating purposes;
or one fastener A on each sash frame can be used for this purpose by fitting two
recessed plates C' at suitable distances apart on the batten rods C.
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 :-
First. The fitting and use of swivelling arms or fasteners on the sliding sash
frames of windows to enter kneed or recessed plates in the batten rods, substantially
as and for the purposes herein described in reference to and shown in the accom-
panying drawings.
Second. The fitting and use of swivelling arms or fasteners on the sliding sash
frames of windows, to pass through holes or slots in weatherproof plates substan-
tially as and for the purposes herein described in reference to and shown in the
accompanying drawings.
