ALFRED ROBERT EUNGBLUT. of No. 69 Brecknock Road London Pianoforte
Maker and EDWARD CROUCH of No. 18 Sydney Road Hornsey Cashier do hereby
declare the nature of this invention to be as follows:-.
The invention relates to an improved device for window and door fasteningsi.
The fastening is of the ordinary pivoted arm type and as shewn in the accom
panying: drawing our device comprises a projection (A) of metal forming part of
the plate (B) which projection laye in an opening (C) cut out of the plate (D). the.
said projection being so placed that it lays over the opening between the two
sashes or between the door and post and immediately under the pivoted handle (E):
when the fastening is closed-as shewn by the dotted lines-the lower edges of
the projection (A) and the upper edges of the cutting (C) being bevelled to allow
of their. more easily fitting the one in the other. and so. keeping the sashes steady.
when closed.....
It is obvious that our device effectually prevents all possibility of, a knife or
other instrument inserted between the sashes forcing the pivoted handle back but
that from the inside the window or door, can be easily unfastened; and opened.in
case of fire or other danger.
It is alsai obvious that our improved window and door fastener can be made in
any suitable design materials and size without departing from the nature of the
said invention..

ALFRED ROBERT EUNGBLUT of No. 69 Brecknock Road London Pianoforte
Maker and EDWARD CROUCH of No. 18 Sydney Road, Hornsey, Cashier 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 invention relates to an improved device for window and door fastenings.
The fastening is of the ordinary pivoted arm type and as shewn in the drawing
accompanying our Provisional Specification (20665 of 1896) our device com-
prises a projection (A) of metal forming part of the plate (B) which projection
Jays in an opening (C) cut out of the plate (D) the said projection being so placed
that it lays over the opening between the two sashes or between the door and post
and immediately under the pivoted handle (E) when the fastening is closed as
shown by the dotted lines in the said drawing, the lower edges of the projection (A)

page_text: and the upper edges of the cutting (C) being 'bevelled to allow of their more
easily fitting the oue in the other and so keeping the sashes steady when closed.
It is obvious that our device effectually prevents all possibility of a kuife or other
instrument inserted between the sashes forcing the pivoted handle back but that
from the inside the window or door can be easily unfastened and opened in case of
fire or other danger.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The construction and employment of a metallic projection of any required
size or design forming part of or attached to the plate Bas before referred to and
being so, placed that it covers and lays completely over the aperture between the
sashes or door and frame.
2. The construction and employment of the metallic projection as before
described (whether applied to or combined with the plate (B) or used in lieu
thereof) in such a manner that when applied to windows it lays preferably but not
necessarily exactly beneath the handle (E) when the latter is drawn across the
sashes and behind the handle when applied to doors.
3. The cutting out of part of the plate (D) of the relative size and design of
the projection before described for receiving the said projection-the projection
fitting within the part so cut out.
4. The bevelling of the edges or sides of the projection and of the part cut out
as before described to enable the latter to easily receive and guide the projection
into its place so that the handle may be drawn across the sashes securely.
5. The construction and employment of the said projection so that when laying
within the part cut out it will keep the sashes steady.
6. The construction and employment of the projection before described in such.
manner as to prevent when in their relative positions a knife used from the outside
passing between the plates B. and D. and thus forcing back the handle E.
7. The improved construction of window and door fasteners and other like
fasteners with projecting parts in such manner as to fasten sashes and doors
substantially as herein before described.
Dated this Thirtieth day of November 1896.
