of Middlesex Clerk in Holy Orders and EDWARD BOYCE PODMORE of Alcester Street
Works Birmingham in the County of Warwick Manufacturer do hereby declare the
nature of this Invention to be as follows :-
Our invention consists in constructing and arranging the parts of sash fasteners in
the manner hereinafter described whereby the said fasteners are made automatic that
is to say the operating of the fastener and the fastening of the sashes is effected by
the depression of the lower sash. Sash fasteners made according to our invention
may by the turning of a thumb plate as hereinafter described be made to lock the
sashes and thereby to prevent their shaking by the action of the wind and the noise
consequent thereon.
Where it is thought desirable the fastener may be operated by
hand instead of being made automatic.
On the base plate fixed to the meeting rail of the top sash we fix a tubular guide in
which a spring bolt slides the said guide and bolt are horizontal and their axis is
perpendicular to the plane of the window. A spring at the rear of the bolt tends to
press it out of the tubular guide and when so pressed out the fore end of the bolt
crosses the junction of the two meeting rails of the sashes and projecting over the
meeting rail of the lower sash prevents the rising of the said lower sash. We will
call the bolt described the fastening bolt.
At the front of the base plate described is a pendent tubular case preferably flat.
In this tubular case a bolt slides the said bolt has a vertical motion and is pressed
upwards by a spring. We will call this bolt the stop bolt. When the fastening bolt
is pressed back by a thumb plate attached to it the stop bolt rises and its top bearing
against the end of the fastening bolt prevents the fastening bolt from being pressed
outwards.
On the meeting rail of the lower sash and immediately opposite the base plate on
the meeting rail of the top sash a flat plate is fixed.
The action of the parts is as follows. The fastening bolt being pressed back into its
guide and held there by the stop bolt the lower sash is liberated and can be raised to
any desired height. On drawing down the lower sash the flat plate carried by it

strikes upon and depresses the stop bolt just before the sash reaches its lowest position.
By the depression of the stop bolt the locking bolt is liberated and being urged
forward by its spring snaps over the said plate and prevents the rising of the lower
sash. The fastening of the sashes is thus automatically effected. The thumb plate by
which the locking bolt is pressed back is connected to the front end of the said bolt
by a screw taking into a screwed hole passing through the end of the bolt.
the lower sash has been drawn down and automatically fastened as described by
turning the thumb plate and driving home the screw its lower end is made to press
firmly on the plate carried by the meeting rail of the lower sash and the two sashes
are bound firmly together the upper sash being pressed upwards and the lower sash
being pressed downwards. In order to liberate the sashes the thumb plate is turned
so as to raise its screw the fastening bolt can now be pressed back into its guide when
the lower sash may be raised. By turning the thumb plate so as to drive home its
screw the bolt may be fixed in its withdrawn position if thought desirable.
Where an automatic action is not required the pendent case and stop bolt may
be dispensed with. In this arrangement the fastening bolt is pressed back by its
thumb plate into its guide and fixed by turning the said thumb plate. The lower
sash can now be raised and lowered. When the lower sash has been drawn down it
is only necessary by acting on the thumb plate to relax its screw when the fastening
bolt being at liberty to move is shot forward by its spring and projecting over the
meeting rail of the lower sash prevents the raising of the said sash.
Sash fasteners made according to our invention cannot be tampered with by a
knife or strip of metal introduced the meeting rails of the sashes.

of Middlesex Clerk in Holy Orders and EDWARD BOYCE PODMORE of Alcester Street
Works Birmingham in the County of Warwick, Manufacturer do hereby declare the
nature of our Invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
Our invention consists in constructing and arranging the parts of sash fasteners in
the manner hereinafter described whereby the said fasteners are made automatic, that
is to say, the operating of the fastener and the fastening of the sashes is effected by
the depression of the lower sash. Sash fasteners inade according to our invention
may by the turning of a thumb plate as hereinafter described be made to lock the
sashes and thereby to prevent their shaking by the action of the wind and the noise
consequent thereon. Where it is thought desirable the fastener may be operated by
hand instead of being made automatic.
On the base plate fixed to the meeting rail of the top sash we fix a tubular guide in
which a spring bolt slides; the said guides and bolt are horizontal and their axis is
perpendicular to the plane of the window. A spring at the rear of the bolt tends to
press it out of the tubular guide and when so pressed out the fore end of the bolt

call the bolt described the fastening bolt.
At the front of the base plate described is a pendent tubular case preferably flat.
In this tubular case a bolt slides; the said bolt has a vertical motion and is pressed
upwards by a spring. We will call this bolt the stop bolt. When the fastening bolt
is pressed back by a thumb plate attached to it the stop bolt rises and its top bearing
against the end of the fastening bolt prevents the fastening bolt from being pressed
outwards.
On the meeting rail of the lower sash and immediately opposite the base plate on
the meeting rail of the top sash a flat plate is fixed. The action of the parts is as
follows The fastening bolt being pressed back into its guide and held there by the
stop bolt the lower sash is liberated and can be raised to any desired height. On
drawing down the lower sash the flat plate carried by it strikes upon and depresses
the stop bolt just before the sash reaches its lowest position. By the depression of
the stop bolt the locking bolt is liberated and being urged forward by its spring snaps
over the said plate and prevents the rising of the lower sash. The fastening of the
sashes is thus automatically effected. The thumb plate by which the locking bolt is
pressed back is connected to the front end of the said bolt by a screw taking into a
screwed hole passing through the end of the bolt. When the lower sash has been
drawn down and automatically fastened as described, by turning the thumb plate and
driving home the screw its lower end is made to press firmly on the plate carried by
the meeting rail of the lower sash and the two sashes are bound firmly together, the

order to liberate the sashes the thumb plate is turned so as to raise its screw; the
fastening bolt can now be pressed back into its guide when the lower sash may be
raised. By turning the thumb plate so as to drive home its screw the bolt may be
fixed in its withdrawn position if thought desirable.
Where an automatic action is not required the pendent case and stop bolt may bo
dispensed with. In this arrangement the fastening bolt is pressed back by its thumb
plate into its guide and fixed by turning the said thumb plate. The lower sash can
now be raised and lowered. When the lower sash has been drawn down it is only
necessary by acting on the thumb plate to relax its screw when the fastening bolt
being at liberty to move is shot forward by its spring and projecting over the meeting
rail of the lower sash prevents the raising of the said sash.
Sash fasteners made according to our invention cannot be tampered with by a
knife or strip of metal introduced between the meeting rails of the sashes.
We will now proceed to describe with reference to the accompanying Drawing the
manner in which our invention is to be performed.
Figure 1 represents in elevation and Figure 2 in plan the meeting rails of the sashes
fastened together by a fastener constructed according to our invention; Figure 3
represents a side elevation and Figure 4 a cross section of the same; Figure 5
represents in section the two sashes unfastened and the lower sash raised, the
horizontal fastening bolt being held in its withdrawn position by the action of
the vertical stop bolt; Figure 6 represents elevations taken at right angles to one
another of the two bolts detached from the sashes; Figure 7 represents in longitudinal
section and Figure 8 in plan the fastening bolt without the stop bolt the fastening bolt
being represented locked in its shot position in Figure 7 and in its withdrawn position
in Figure 8.
We will first describe the automatic sash fastener.
The same letters of reference indicate the same parts in the several Figures of the
Drawing.
a is the meeting rail of the lower sash and b the meeting rail of the top_sash; c is
the tubular guide or case fixed on the meeting rail, 6 of the top sash. In the said
guide or case c the horizontal fastening bolt a slides the said bolt being pressed
outwards by a coiled spring d², a stop pin e on the bolt traversing a slot in the bottom
of the guide or case e limiting the outward motion of the said bolt. When the spring
fastening bolt d is in its shot or projected position Figures 1. 2. 3 and 4 its front end
bears upon the top of the flat plate fixed on the meeting rail a of the lower sash and
by crossing the junction of the meeting rails of the two sashes prevents the rising of
the said lower sash as best seen in Figures 3 and 4. The fastening bolt d is pressed
back by means of the thumb plate g the screw of which takes into the screwed hole
ath made in the fore end of the said bolt d. By driving home the screw of the
thumb plate g the bolt d can be locked in its fastening position or in its pushed back
position as hereinafter described.
is the pendent flat case at the front of the meeting rail 6 of the top sash. In the
said case the vertical stop bolt i works the said bolt i being pressed upwards by the
spring. This stop bolt is pressed into its case on the depression of the lower sash
by the reduced projecting or overhanging part of the plate f fixed on the meeting
rail a of the said lower sash as hereinafter described.
In order to unfasten the sashes the thumb plate g is turned so as to unlock the
fastening bolt d from the plate and the said thumb plate is pressed back so as to
push the fastening bolt d into its guide or case c. The fastening bolt d having been
pushed back the vertical stop bolt i rises in front of the said bolt d and holds it in
that position as represented in Figure 5. The lower sash a being thus liberated can
be raised to any desired height as seen in the said Figure 5. When the lower sash a
is depressed the overhanging part of the plate fon its meeting rail strikes upon and
depresses the stop bolt i just before the said sash a reaches its lowest position. This
depression of the stop bolt i liberates the spring fastening bolt d and the said bolt d
being urged forward or outward by its spring snaps over the said plate as represented

page_text: in Figures 1. 2. 3 and 4 and the sashes a and b are thus automatically fastened. By
turning the thumb plate g and driving home its screw the lower end of the said screw
is made to press firmly on the plate on the meeting rail a so as to bind the two
sashes together by pressing them in opposite directions and thereby prevent the
shaking and rattling of the said sashes. By driving home the screw of the thumb
plate after the bolt a has been pushed back the said bolt may be fixed in its
withdrawn position as represented in Figure 5, the bottom of the screw of the thumb
plate in this case seating itself in a seat or depression at the bottom of the tubular
guide c.
When the sash fastener is used without the automatic action herein before described
the parts are constructed in the manner represented in Figures 7 and 8. In this
arrangement the plate on the meeting rail a of the lower sash is furnished with a
circular seats for the end of the screw of the thumb plate g to take into for fixing
the spring fastening bolt in its projected or fastening position and for binding the two
sashes together as represented in Figure 7, the fixing of the bolt d in its withdrawn
position Figure 8 being effected in the manner herein before described, that is, by the
end of the screw of the thumb plate y seating itself in a seat in the bottom of the
guide or case c of the said bolt d.
Having now particularly described and ascertained the nature of our Invention
and the manner in which the same is to be performed we declare that we claim
as our invention of "Improvements in sash fasteners" :-
First The combination of the horizontal spring fastening bolt d and vertical spring
stop bolt i on the meeting rail of the top sash with the plate on the meeting rail of
the bottom sash as herein before described and illustrated in the accompanying
Drawing, whereby the fastening bolt d is held in its back or withdrawn position by
the stop bolt or unfastening the sashes and the fastening bolt released and the sashes
automatically fastened on the depression of the bottom sash by the action of the plate
on the said bottom sash upon the said stop bolt, the several parts being constructed
arranged and acting substantially as herein before described and illustrated.
Secondly-Fixing the spring fastening bolt of the sash fastener in its projected or
fastening position and binding the two sashes together and fixing the said bolt in its
withdrawn or pushed back position by means of a screwed thumb plate passed through
a screw box or screwed hole in the fore end of the bolt substantially as herein before
described and illustrated in the accompanying Drawing whether the screwed thumb
plate be used with the sash fastener having the automatic action claimed in claim 1 or
without the said automatic action.
