page_text: I FREDERICK Cox of 4 Nottidge Villas, Earlsfield Road, Wandsworth in the
County of Surrey, Hardware Traveller do hereby declare the nature of this
invention to be as follows:-
The object of my invention is to produce secure and simple fasteners suitable for
sashes, casements, doors and similar purposes, in such manner that they cannot be
opened from the outside by the insertion of a knife or other flat instrument
between the meeting rails, while the sashes, casements doors or other articles are
held closely together and in the case of sashes they are prevented from shaking:
and falling.
According to my invention I fix to each metal meeting rail plate a portion of a
disc or circular plate the metal plate and the disc being sufficient distance apart to
allow the fastening catch to work between them which it does about an axis which
connects one portion of the disc and the meeting rail plate. The other meeting
rail plate is connected to the other portion of the disc by a piece which forms the
grip for the fastener or is embraced by the fastener. This fastener consists of a
curved arm of spiral formation at one end the said spiral end of which is free to
move round the plate and disc axes the other end terminating in a handle knob,
so that when the fastener is turned round its axis the spiral end thereof makes an
eccentric movement about its axis and when it has made its complete rotation the
curved arm of the fastener has embraced the connecting piece on the other meeting
rail plate which connecting piece fills up the space between the curved arm of the
fastener and its axis. There is a notch on the curved end of the fastener which
when the fastener is back or unfastened comes against a pin or stud on the under-
side of the disc which acts as a stop to prevent the fastener going too far round or
from making more than one half turn in either direction because on the return
motion the same stud acts as a stop to the other end of the handle.

Purposes.
I, FREDERICK Cox, of 4 Nottidge Villas, Earlsfield Road, Wandsworth in the
County of Surrey, Hardware Traveller do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
The object of my invention is to produce secure and simple fasteners suitable for
sashes, casements, doors and similar purposes in such manner that they cannot be
opened from the outside by the insertion of a knife or other flat instrument
between the meeting rails while the sashes, casements doors or other articles are
held closely together and in the case of sashes they are prevented from shaking
and falling.
In order that my invention may be fully understood and readily carried into
effect I will now proceed to describe the same with reference to the accompanying
drawings.
Figure 1 shows in elevation, and Figure 2 in plan, a sash fastener constructed
according to my invention; Figure 3 is a plan with the cover plate removed (the
connection of same in section) of a similar fastener showing the position of bolt
when in the open or unfastened position, and Figure 4 is a similar view showing
position when closed or fastened.
According to my invention I fix to each metal meeting rail plate A A¹ a portion
of a disc or circular plate B B¹ the metal rail plates A A¹ and the divided disc B B¹
being sufficient distance apart to allow the fastening catch C to work between
them that is between plates B B¹ and plates A A¹ which it does about an axis D
which connects one portion of the disc B and the meeting rail plate A. The other
meeting rail plate AI is connected to the other portion of the disc B' by a piece E
which forms the grip for the fastener C, or is embraced by the said fastener C.
This fastener C consists of a curved arm of spiral formation at one end the said
spiral end of which is free to move round the plate and disc axis D the other end
terminating in a handle knob C¹ so that when the fastener is turned round its
axis D the spiral end thereof makes an eccentric movement about its axis and
when it has made its complete rotation the curved arm of the fastener has embraced
the connecting piece E on the other meeting rail plate A¹ which connecting piece E
fills up the space
between the curved arm of the fastener C and its axis D. There
is a notch C on the curved end of the fastener which when the fastener is back or
unfastened as shown in Figure 3 comes against a pin or stud G on the underside of
the disc B which acts as a stop to prevent the fastener going too far round or from
making more than one half turn in either direction because on the return motion
the same stud G acts as a stop to the other end of the fastener C.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. In fastenings for sashes, casements and other purposes the spiral and eccen-
trically working fastener C on one plate A in combination with connecting piece E
on the other plate A¹ substantially as and for the purposes set forth.
2. In sash and casement and other fasteners the fastener of spiral formation
substantially as and for the purpose set forth.
