Fasteners and other Analogous Purposes.
We, EDWARD VERNON BAILEY, and CHARLES MACKEY of Great Hampton Row,
Birmingham, in the County of Warwick Brass Founders, do hereby declare the nature
of our invention for "AN IMPROVEMENT IN CASEMENT FASTENERS, APPLICABLE ALSO
TO SASH FASTENERS AND OTHER ANALOGOUS PURPOSES to be as follows:-
Our improvement consists in the construction of a Casement fastener applicable
also to Sash Fasteners and other analogous purposes having an arm with a semi-
circular eccentric grip, turning and working upon a metal plate which is intended
to be fixed upon the front or nearest side of the casement, and upon being turned
in the act of securing the casement together, the eccentric grip. takes hold of a
stud fixed upon a plate on the opposite side and braces them together.
The arm of this fastener is actuated by a spring fixed on the front of the plate
just where the casement sash meets, such spring lying and bearing upon a flat
surface below the semi-circular grip, the object in view being the prevention of
opening the window casement by the insertion of a knife or other instrument between,
for by virtue of the spring and flat surface of the arm being parallel with the
meeting of the casement, the introduction of anything between, instead of moving
the arm, simply binds it and renders it immoveable.
We do not however strictly confine ourselves to the foregoing details as they may
be open to some slight modification.

We EDWARD VERNON BAILEY and CHARLES MACKEY of Great Hampton Row,
Birmingham, in the County of Warwick, Brass Founders, 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 :-
Our improvement consists in the construction of a casement fastener applicable also
to Sash Fasteners and other analogous purposes, having an arm-A Fig. 1-with a
semicircular eccentric grip turning and working upon a metal plate-B-which is
intended to be fixed upon the front or nearest side of the casement, and upon
being turned in the act of securing the casement together, the eccentric grip takes
hold of a stud-C--fixed upon a plate-D-on the opposite side and braces them
together.
The arm of this fastener is actuated by a spring-E-fixed on the front of the plate
just where the casement sash meets, such spring lying and bearing upon a flat
surface- below the semicircular grip, the object in view being the prevention of
opening the window casement by the insertion of a knife or other instrument between,
for by virtue of the spring and flat surface of the arm being parallel with the meeting
of the casement, the introduction of anything between, instead of moving the arm,
simply binds it and renders it immoveable.
Fig. 2 is a side section of Fig. 1.
Fig. 3 is a top view of back-plate-D.
Fig. 4 is a side view of Fig. 3.
Fig. 5 is another view of Fig. 1. with arm released from stud-C--and thrown back
so as the casement or sash may be opened.
Fig. 6 is a view of plate-B-with an arm thereon.
Fig. 7 is an end view of same.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is
1 An arm having a semicircular eccentric grip turning and working upon a stud
or pin in a metal plate fixed upon the front or nearest side the casement and being
actuated by a spring substantially as described and illustrated by the accompanying
drawings.
2 The prevention of opening the casement substantially as described and illustrated
by the said drawings.
3-The bracing of the casement sashes together substantially as described and
illustrated by the said drawings.
