COMPLETE SPECIFICATION.
A New or Improved Casement Fastener.
I, JAMES HUISH, of Parson Street, Porlock, Somerset, Builder, 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:-
My invention relates to a new or improved casement fastener or fastening
device and has for its object to provide simple and effective means for easily and
securely fastening casements and the like.
In carrying my invention into practical effect, my improved casement fastener
comprises a rod of sufficient length supported at each end in suitable bearing
pieces in which it is free to turn, said bearing pieces being secured to the one part
of the casement. This rod is centrally furnished, preferably with an ornamental
piece, by means of which it may be turned, while at each end it carries a projecting
hooked portion designed to engage with projecting curved plates secured to the
other part of the casement and in such a manner that when the hooked portions
of the rod engage with same the casement is securely fastened at two points.
In order that my invention may be more fully understood, I will now proceed
to describe same with reference to the accompanying drawings in which Fig. 1
is a side elevation of my improved casement fastener showing the rod with the
hooked portions, also the curved projecting plates with which said hooked portions
engage, one of the curved plates being shown in end elevation, while Figs. 2, 3,
and 4 are sectional views illustrating the application of this invention to casements
of various forms.
My improved casement fastener comprises a rod r of sufficient length carried
at each end in suitable supports or bearing pieces a, said rod being furnished near
each end with a projecting hooked portion and at or about the centre with an
ornamental piece b by means of which the rod r is turned. The rod r and its
supports are carried by one part of the casement or casement frame, while I
further provide two curved plates p secured to the second part of the casement or
casement frame and with which projecting hooks h of the rod engage in such a
manner as to closely secure the two parts of the casement together.
Fig. 2 shows the application of my improved fastener to a casement in which
form the rod r and its hooked portions are carried by the opening casement g
while the curved plates p with which the hooked portions / engage are carried by
a portion of the frame f.
Fig. 3 illustrates the application of my invention to a single casement and
frame, in which case the rod r and its attachments are carried by the opening
casement g, the curved plates ? being secured to the frame f.
Fig. 4 shows a further application of my invention in which g represents the
opening casement and g¹ the fixed casement.
The rod of the casement fastener may be of any length to suit all sizes of
casements, while it may be made of brass, iron or other suitable material as
required, the advantages of my improved fastener being that it can be put on in
a small space, it grips the sash at two points, and while affording a secure
D.

page_text: fastening it prevents the sash from warping, it is further of few and simple parts
and not liable to readily get out of order.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The new or improved casement fastener substantially as herein described and
shown, and for the purposes specified.
2. An improved casement fastener comprising a rod such as with projecting
hooked portions h and turning piece 6 supported by end bearing pieces a in such
a manner that it is free to turn in combination with curved plates p, the whole
arranged substantially as herein described and shown, and for the purposes
specified.
