YEUNAD DITETICATION.
Improvements in Fastenings for Sashes, Casements, and other
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
to be as follows:-
.
The object of my present invention is to produce, secure and simple fastenings
suitable for window and other 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.
Heretofore in fastenings of the class to which my invention refers, there has been
much difficulty experienced in casting the several parts in such manner as to put
them together accurately without breaking or straining them; and in addition to
this there has been a difficulty experienced in casting the parts sufficiently accurate
that the curved or spiral arm could be brought round to its place without specially
adjusting the sashes, and considerably straining and sometimes breaking the spiral arm;
by my present invention these defects are obviated and greater strength and security
are obtained than heretofore.
Instead of making the fastening catch of spiral form I make it of semi-circular
disc like form, or rather more than a semi-circle, thus providing sufficient metal beyond
the centre to take the axle which latter may be cast in a piece with the catch, and the
axle being the centre the catch can be turned up in a lathe when required with the
greatest facility. The underside of this catch is hollowed out and on the opposite or

page_text: reverse plate there is a projection to correspond with this hollowed out portion and
into which the latter takes when brought round and over same. The catch or disc is
boxed over by a cap which is rivetted to the bottom plate by pins. The above
projection on the other plate is also boxed over in a like manner and so that when the
disc or catch is turned it covers the aforesaid projection and enters the box, leaving
the solid portion of the disc over the point of junction of the two meeting rails. The
catch or disc is worked by a handle on the axle outside the box which handle may be
of any suitable design to suit the purpose to which the fastening is applied. For a
single casement fastening one plate, instead of having a projection on it is provided
with an aperture for the catch to enter. There is a stop in the cap to regulate the
throw of the catch or disc which latter (as well as the plate and cap) is bevilled so as
to allow the parts to come together and to work freely one in the other.

Improvements in Fastenings for Sashes, Casements, and other
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 present invention is to produce secure and simple fastenings suitable
for window and other sashes, casements, doors, and similar purposes, in such manner tha
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.
Heretofore in fastenings of the class to which my invention refers, there has been
much difficulty experienced in casting the several parts in such manner as to put them
together accurately without breaking or straining them; and in addition to this there
has been a difficulty experienced in casting the parts sufficiently accurate that the
curved or spiral arm could be brought round to its place without specially adjusting
the sashes and considerably straining and sometimes breaking the spiral arm; by
my present invention these defects are obviated and greater strength and security are
obtained than heretofore.
My invention will be best understood by reference to the accompanying drawings.
Figure 1 is a perspective view of a fastening for sashes, casements, and other
purposes constructed according to my invention.
Figure 2 is a horizontal section of the fastening shewing same open or unfastened.
Figure 3 is a similar view shewing same closed or fastened.
Figure 4 is an isometric view of the hollowed out disc fastening bolt shewn in an
inverted position.
Figure 5 is a front elevation of the disc and plate of the fastener.
Similar letters of reference refer to like parts in all the figures.
Instead of making the fastening catch or bolt A of spiral form I make it of
semi-circular disc like form, or rather more than a semi-circle and as shewn in the
drawings thus providing sufficient metal beyond the centre to take the axle B which
latter may be cast in a piece with the catch A and the axle B being the centre the
catch A can be turned up in a lathe when required with the greatest facility. The
underside of this catch A is hollowed out as shewn at Figures 4 and 5 and is centred
on the plate E, and on the opposite or reverse plate there is a projection C to correspond
with this hollowed out portion and over which the hollowed disc A takes when the
latter is brought round or rotated over same into the position as shewn at Figure 3.
The catch or disc A is boxed over by a cap D which is rivetted to the bottom plate E
by pins proferably cast on the cap D. The above projection C on the other
plate F is also boxed over in a like manner by a casing Ď₁ and so that when the

page_text: plates E and F are brought together the two parts of the casing D D' form a complete
circular cover. When the disc or catch A is turned it covers the aforesaid projection (
entering the box D' and leaving the solid portion of the disc A over the point of
junction of the two meeting rails or plates E and F. The catch or disc A is workod
by a handle G on the axle outside the box which handle may be of any suitable design
to suit the purpose to which the fastening is applied. For a single casement fastening
one plate instead of having a projection on it is provided with an aperture for the
catch to enter. There is a stop as shewn by letter H in the cap to regulate the throw
of the catch or disc A, which latter is bevelled so as to allow the parts to come well
together. The edge of the disc is rounded and the flanged edge is also rounded as
will be clearly seen by reference to Figure 4 of the drawings, in order to prevent any
rattle and to cause the parts to work freely one in the other.
at Figure 4 which when required is placed between one of the plates or meeting rails
I is a flat spring shewn
and the underside of the catch A to hold the catch firmly in position and to prevent
any shaking of the parts and especially in fastenings of cheap manufacture; or the
spring may be rivetted on the underside of plate E project through a slot in same and
act on the flange of the disc A.
my
Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed 1 declare that what
said
I claim is
First. In fastenings the catch A of the form and shape shewn with its spindle or
axle B substantially as and for the purposes set forth.
Second. The combination of catch A provided with spindle or axis B with projection C
on meeting rail and boxed or cased over and operated by handle outside all substan-
tially as hereinbefore described and illustrated with reference to the accompanying
drawings.
