JOHN WHITEHOUSE of the firm of John Whitehouse and Sons of Birmingham in
the County of Warwick Manufacturers and SEPTIMUS PEACOCK of Birmingham
aforesaid Machinist "IMPROVEMENTS IN SASH FASTENINGS
"
Our invention consists of the construction and combination herein after described
of the parts of sash fastenings.
In constructing a sash fastening according to our invention we use a flat bolt
sliding in a case on one part of the fastening which bolt takes into a staple on the
other part of the fastening. This sliding bolt is without a spring and is shot and
withdrawn by means of a lever or arm and appliances connected therewith as
hereinafter described.
The said lever or arm also serves to pull or draw and hold together the two
parts of the sash fastening and the sashes to which they are connected. The said
drawing together and holding lever is situated on the outside of the bolt case and
its free end is hooked to engage with a headed stud on the top of the staple into
which the sliding bolt is shot. The hooked end of the lever when closed upon the
stud exerts a pulling up action upon the sash carrying the staple and thereby
draws it towards and holds it to the other sash.
The drawing up and holding lever is made to work the sliding bolt in the
following manner. The axis on which the lever turns carries a disc having on its
underside an eccentric pin or stud which works in a cross slot in the bolt. By the

page_text: partial rotation in one or other direction of the disc its eccentric stud working in
the cross slot in the bolt shoots or withdraws the bolt.
We do not limit ourselves to the arrangement of the eccentric stud and cross
slot for effecting the motion of the bolt as other analogous arrangements may
be used.
On moving the drawing up and holding lever for fastening the sashes it first
causes the bolt to be shot into its staple and the hooked end of the lever afterwards
engaging with the stud on the staple draws and holds together the two sashes
On moving the drawing up and holding lever for fastening the sashes the bolt is
not withdrawn from the staple until the said lever-has-been-moved through such
an angle as to bring it considerably beyond the junction of the two sashes. By
this arrangement the unfastening of the sashes by the pushing back of the drawing
up and holding lever by a knife or instrument introduced between the sashes is
prevented as the knife or instrument cannot push back the said lever sufficiently
far to cause it to withdraw the bolt.

JOHN WHITEHOUSE of the firm of John Whitehouse and Sons of Birmingham in
the County of Warwick Manufacturers and SEPTIMUS PEACOCK of Birmingham
aforesaid Machinist.. "IMPROVEMENTS IN SASH FASTENINGS"
...":"
Our invention consists of the construction and combination herein after, described
of the parts of sash fastenings.
In constructing a sash fastening according to our invention; we use a flat bolt
sliding in a case on one part of the fastening which bolt takes into a staple on the
other part of the fastening. This sliding bolt is without a spring and is shot and
withdrawn by means of a lever or arm and appliances connected therewith as
hereinafter described. The said lever or arm also serves to pull or draw and hold
together the two parts of the sash fastening and the sashes to which they are
connected. The said drawing together and holding lever is situated on the outside
of the bolt case and its free end is hooked to engage with a headed stud on the
top of the staple into which the sliding bolt is shot. The hooked end of the lever
when closed upon the stud exerts a pulling up action upon the sash carrying. the
staple and thereby draws it towards and, holds it to the other sash.
г
The drawing up and holding lever is made to work the sliding bolt in the
bolt in the
following manner. The axis on which, the lever is, fixed carries a disc having on
its underside an eccentric pin or stud which works in a cross slot in the bolt.
By the partial rotation in one or other direction of the disc its eccentric stud
working in the cross slot in the bolt shoots or withdraws the bolt. We do
not limit ourselves to the arrangement of the eccentric stud and cross slot
for effecting the motion of the bolt as other analogous arrangements may be used.
On moving the drawing up and holding lever for fastening, the sashes it first causes
the bolt to be shot into. its staple and the hooked end of the lever afterwards
engaging with the stud on the staple draws and holds together the two sashes.
On moving the drawing up and holding lever for unfastening the sashes the bolt is
not withdrawn from the staple until the said lever has been moved through such
an angle as to bring it considerably beyond the junction of the two sashes. By
this arrangement the unfastening of the sashes by the pushing back of the drawing
up and holding lever by a knife or instrument introduced between the sashes is
prevented as the knife or instrument cannot push back the said lever sufficiently,
far to cause it to withdraw the bolt.
We will now proceed to describe with reference to the accompanying Drawing
the manner in which our invention is to be performed.
ป
Figure 1 represents in plan and Figure 2 in cross section, a sash fastening
constructed according to our invention, the sashes being represented unfastened
Figure 3 represents in plan and Figure 4 in cross section the said sashes fastened
Figure 5 represents the two parts of the sash fastening in horizontal section an
the staple part in end elevation; Figure 6 represents a plan of the underside of
one part of the fastening; Figure 7 represents the bolt, separately, and Figure 8
represents the case of the bolt separately and Figure 9 represents the disc and its
excentric pin or stud detached from the fastening.
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 is the meeting rail of, the upper
sash. On the meeting rail a the fastening proper is fixed and on the meeting

page_text: rail b, the staple c is fixed. The fastening on the meeting rail a consists of a flat
cased (shown separately in Figure 8) in which a flat bolt e (shown separately in
Figure 7) slides. The bolt case d is secured to the foundation or fixing plate ƒ by
ears or lugs on the edges of the said case d being passed through and rivetted in
holes in the said foundation or fixing plate. The sliding bolt e is without a spring
and is shot and withdrawn by means of the arm or lever g on the top of the case d,
the said arm or lever g also serving to pull or draw and hold together the two
parts of the sash fastening The axis h (see Figure 9) to which the arm or lever g
is fixed has a circular part he which turns in a circular opening i in the bolt case d
and the said axis carries an eccentric disc k having on its underside the pin or
stud which works in a cross slot m in the sliding bolt e (see Figure 5) It is by
means of the said pin working in the slot m that the shooting and withdrawing
of the bolt e is effected the said bolt working closely in its case d.
In order to permit of the nearly circular motion of the pin 7 to shoot or with-
draw the bolt, a nearly circular slot n is made in the foundation plate ƒ for the
said pin to work in (see Figure 6). The arm or lever g to which the eccentric
pin or stud is connected is hooked at its free end, the hooked part being marked g².
The nose part of the hooked end is slightly inclined as represented. This hooked
end, when the lever is moved into its fastening position, engages with the neck of
the stud p on the staple c and the said hooked end exerts a pulling up action upon
the sash b and thereby draws it towards and holds it to the other sash a.
When the parts of the sash fastening are in the respective positions represented
in Figures 1, 2, 5 and 6, the sashes are unfastened the arm g having been turned
back through about three fourths of a circle so as to disengage the hooked end g²
of the said arm from the stud p and withdraw the bolt e from the staple c the
withdrawal of the bolt being effected by the action of the pin ɩ in the cross
slot m in the said bolt.
f
In order to fasten the sashes the arm or lever g is turned from the position
represented in Figures 1 and 2 to that represented in Figures 3 and 4. On moving
the arm or lever g through a semi-circle the bolt e is shot into its staple c by the
action of the pin and slot l, m and the hooked end g² of the lever g afterwards
engaging with the stud p on the staple draws and holds together the two sashes.
The two sashes are thus first bolted together by the motion of the arm or lever g
through a semi circle and afterwards drawn and held together by the motion of the
said arın or lever g through a quadrant.
In Figure 1 the arm or lever g is indicated in dotted lines in the position which
it occupies just as the inclined nose part of its hooked end g' commences to exert
a pulling up action upon the sash 6 through the stud p.
As the arm or lever g in its unfastening motion does not commence to operate
upon the bolt e until the said arm has moved through a quadrant from the position
Figure 3 so as thereby to bring it considerably beyond the junction of the two
sashes a, b it results that the unfastening of the sashes by the pushing back of the
arm or lever by a knife or instrument introduced between the sashes is prevented,
the said knife or instrument being unable to operate upon the arm sufficiently to
cause it to withdraw the bolt as will be understood by an examination of the drawing.
Instead of shooting and withdrawing the bolt by means of the eccentric pin
the axis of the hooked lever g, g² may be cranked and the end of the cranked axis
be made to work in the cross slot m in the bolt and in the nearly circular slot n
in the foundation plate as described with respect to the eccentric pin l.
We prefer
however to use the arrangement of parts represented in the drawing.
Having now described the nature of our invention and the manner in which
the same is to be performed we wish it to be understood that We claim as our
invention of "Improvements in sash fastenings" :-
First Shooting and withdrawing the springless bolt of the fastening by means
of an eccentric stud connected with an arm or lever turning in the bolt case
working in a cross slot in the bolt, or by means of the cranked end of the arm or
lever working in the said cross slot in the bolt, the several parts of the fastening

page_text: being constructed, combined and working substantially as hereinbefore described
and illustrated in the accompanying Drawing.
Secondly-The combination with the mechanism described and illustrated for
shooting and withdrawing the sliding bolt of the fastening of the hooked arm or
lever described and illustrated for drawing up and holding together the fastened
sashes; that is to say, combining the drawing up and holding hooked arm or lever
with the sliding bolt in such a manner that the motion of the said arm or lever
through about a quadrant from its fastening position does not operate the sliding
bolt as herein before described.
In witness whereof we the said John Whitehouse and Septimus Peacock have
hereunto set our hands and seals this Twenty third day of May in the year
of our Lord one thousand eight hundred and eighty three.
