New or Improved Window Sash Fasteners.
1 EDWARD EDWARDS of Parkhurst Lodge Eriswell Road Worthing in the County
of Sussex Gentleman do hereby declare the nature of this Invention to be as
follows:-
My invention consists of new or improved window sash fasteners the parts
of which are constructed arranged and act substantially as hereinafter described.
My new or improved sash fasteners are of two kinds one form being self acting and
the other has to be put into action by a hand screw.
My said invention consists of self acting grasps for the purpose of drawing
together the two sashes as they are closed and of screw grasps for drawing together
the two sashes after they have been closed and for fastening the sashes.
I will first describe the self-acting grasp.
The said grasp is situated on the meeting rail of the bottom sash and the catch with
which the grasp engages is situated on the meeting rail of the top sash and opposite
the said grasp. The grasp is made preferably adjustable for compensating for
wear but it may be fixed to and form part of the case fixed to the meeting rail. The
adjustable grasp consists of a rectangular frame or loop sliding in a case fixed to the
meeting rail the inner end of the said loop projecting over and crossing the junction
of the meeting rails of the two sashes. The outer end of the loop is formed into a
screw box in which a quick threaded screw works provided with a head external to
the case for turning it. This screw is only capable of a rotary motion. By turning
the screw in the proper direction the acting end of the loop or grasp can be made to
project the required distance over the meeting rail of the top sash to obtain the
required pull or grasp upon the catch. The catch on the meeting rail of the top sash
consists of a short upright the upper part of the inner face, of which is bevilled or
inclined. When the sashes have nearly reached their closed position in the act of
closing the sashes the loop or grasp passes over the bevilled end of the catch and
engaging below the bevilled part of the catch draws or pulls together the two
sashes. When the grasp is used as a screw grasp and fastener combined a modified
catch is employed.

page_text: In this modified catch a horizontal notch or shoulder is made at the base of the
incline at the top of the catch. With this notch or shoulder the projecting end of
the loop or grasp engages when the sashes are closed and in order to draw or pull
together and fasten the sashes the screw of the grasp has to be turned in the
proper direction to cause the said grasp to move outwards or towards the interior
of the room and thereby bear upon the catch and pull the sashes together and fasten
them.
I combine the self acting grasp described with the window sash-fastener and
appliances described in the provisional specification filed with my application for
patent on the 6th day of October 1888 No. 14402 and when combined together the
grasp and the horizontal bolt engaging with the rack catches may be enclosed in the
same case fixed to the meeting rail of the bottom sash..

page_text: I EDWARD EDWARDS of Parkhurst Lodge, Eriswell Road, Worthing in the County.
of Sussex, Gentleman, do hereby declare the naturo 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 :-
My invention consists of new or improved window sash fasteners the parts of which
are constructed arranged and act substantially as hereinafter described.
My new or improved sash fasteners are of two kinds, one form being self acting and
the other has to be put into action by a hand screw.
My said invention consists of self acting grasps for the purpose of drawing together
the two sashes as they are closed and of screw grasps for drawing together the two
sashes after they have been closed and for fastening the sashes.
I will first describe the self acting grasp. The said grasp is situated on the meeting
rail of the bottom sash and the catch with which the grasp engages is situated on the
meeting rail of the top sash and opposite the said grasp. The grasp is made
preferably adjustable for compensating for wear but it may be fixed to and form part
of the case fixed to the meeting rail. The adjustable grasp consists of a rectangular
frame or loop sliding in a case fixed to the meeting rail the inner end of the said loop
projecting over and crossing the junction of the meeting rails of the two sashes. The
outer end of the loop is formed into a screw box in which a quick threaded screw
works provided with a head external to the case for turning it. This screw is only..
capable of a rotary motion.. By turning the screw in the proper direction the
acting end of the loop or grasp can be made to project the required distance over
the meeting rail of the top sash to obtain the required pull or grasp upon the
catch. The catch on the meeting rail of the top sash consists of a short. upright
the upper part of the inner face of which is bevilled or. inclined.
When the sashes have nearly reached their closed position in the act of closing
the sashes the loop or grasp passes over the bevilled end of the catch and
engaging below the bevilled part of the catch draws or pulls together the two
sashes.
When the grasp is used as a screw grasp and fastener combined a modified catch
is employed.
In this modified catch a horizontal notch or shoulder is made at the base of the
incline at the top of the catch. With this notch or shoulder the projecting end of
the loop or grasp engages when the sashes are closed and in order to draw or pul!
together and fasten the sashes the screw of the grasp has to be turned in the
proper direction to cause the said grasp to move outwards or towards the interior
of the room and thereby bear upon the catch and pull the sashes together and
fasten them.
I combine the self acting grasp described with the window sash fastener and
appliances described in the provisional specification filed with my application for

page_text: patent on the 6th day of October 1888 No. 14402 and in the complete specification
subsequently filed and when combined together the grasp and the horizontal holt
engaging with the rack catches may he enclosed in the same case fixed to the meeting
rail of the bottom sash.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which my invention is to be performed.
Figure 1 represents in front elevation; Figure 2 in plan partly in horizontal
section and Figure 3 in vertical section portions of the sashes of a window to
which a self acting grasp constructed according to my invention is applied, the
said self acting grasp being represented in combination with the window sash
fastener described, represented and claimed in the specifications of my application for
patent herein before referred to.
The same letters of reference indicate the same parts in Figures 1, 2 and 3.
a is the meeting rail of the top sash and 6 is the meeting rail of the bottom sash.
On the said meeting rail b the horizontal spring bolt c in the case d is fixed the said
horizontal bolt engaging with the rack catch e on the side of the upper sash to fasten
the two sashes together. These parts constitute no part of my present invention.
Made preferably in one piece with the case d containing the horizontal bolt c and its
appliances is a supplementary case d² in which the adjustable grasp f is situated and
works. On the meeting rail a of the top sash and opposite the adjustable grasp f
on the meeting rail b, the vertical catch g is fixed with which the grasp engages for
drawing together the two sashes as they are closed. The catch g consists of a short
upright the upper part of the inner side of which is bevilled or inclined as seen in
Figure 3. The said adjustable grasp consists of a rectangular frame or loop
sliding in the case d² the inner or loop end of the said grasp projecting
over and crossing the junction of the meeting rails a b of the two sashes as
seen in Figures 2 and 3; h is a screw box on the outer end of the sliding
grasp in which screw box the quick threaded screw i works the said screw
being turned by the head k. external to the case . The said screw i is only
capable of a rotary motion, the boss l near the head k of the screw working in the
trough shaped bearing m on the bottom plate of the case (see Figure 3), collars on
either side the boss preventing the advance of or end motion in the screw. By
turning the screw in the proper direction the loop or inner end of the
grasp
made to project the required distance over the meeting rail a of the top sash to obtain
the desired pull or grasp upon the catch on the said top sash.
can be
Although I prefer to make the self acting grasp adjustable as described and
illustrated for compensating wear yet the loop part of the grasp may be fixed to or
form part of the case d. In this modification the additional case d² is dispensed with
and the loop of the grasp is made upon the bottom plate of the case d or upon an
independent plate fixed to the meeting rail a of the top sash.
The action of the self acting grasp is as follows:- When the sashes have nearly
reached their closed position in the act of closing them the loop or grasp on the
meeting rail b passes over the bevilled end of the vertical catch g on the meeting rail a
and engaging below the said bevilled part of the catch pulls together the two sushes as
seen in the Drawing.
The self acting grasp represented in Figures 1, 2 and 3 may be used independently
of the sash fastener with which it is shown in combination.
Figure 4 represents in front elevation; Figure 5 in plan, partly in horizontal
section, and Figure 6 in vertical section, my improved hand worked screw grasp and
sash fastener. This grasp or sliding loop f is carried by an independent case d³
and is constructed in the same manner as the adjustable looped grasp hereinbefore
described and corresponding parts are marked with the same letters of reference, but
the catch n fixed on the meeting rail a of the top sash is made with a horizontal
notch or shoulder P at the base of the incline on the said catch. When the sashes are
closed the projecting end of the loop or grasp passes below the notch or shoulder
and in order to draw or pull together and then fasten the sashes the screw i of the
grasp is turned by the head in the proper direction to cause the loop end of the

page_text: grasp to engage under the said notch or shoulder and bear upon the stem of the grasp
and pull the sashes together and fasten them as will be understood by an
examination of Figure 6. In order to unfasten the sashes the hand worked
screw grasp is moved backwards by turning the screw i so as to cause its loop
end to project beyond the shoulder p on the catch n when the sashes may be
opened.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I
claim as my invention
First The new or improved window sash fastener herein before described and
illustrated in Figures 1, 2 and 3 of the accompanying Drawings the said window
sash fastener consisting of an adjustable or non-adjustable grasp on the meeting rail
of the bottom sash and an inclined or bevilled catch or upright on the meeting rail
of the top sash with which catch or upright, the loop end of the grasp engages in the
act of closing the sashes and thereby draws or pulls together the said sashes, the
several parts being constructed and combined substantially as described and
illustrated.
Secondly-The new or improved window sash fastener herein before described and
illustrated in Figures 4, 5 and 6 of the accompanying Drawings the said window
sash fastener consisting of a hand worked screw grasp and catch or upright having
a horizontal shoulder or notch for drawing or pulling together and fastening the two
sashes after they have been closed the several parts being constructed and combined
substantially as described and illustrated.
