Sealed the 7th June 1864, and dated the 10th December 1863.
PROVISIONAL SPECIFICATION left by the said Richard William Pyne
at the Office of the Commissioners of Patents, with his Petition, on the
10th December 1863.
I, RICHARD WILLIAM PYNE, of Grove Lane, Camberwell, in the County
of Surrey, Builder, do hereby declare the nature of the said Invention for
"AN IMPROVED SASH OR SHUTTER FASTENER, ALSO APPLICABLE TO DOORS AND CASE-
MENTS," to be as follows:-
My Invention relates to an improvement in the fastenings of window
sashes, shutters, doors, casements, and similar articles. I make use of a metal
plate, attached to which by a hinge is a tongue or flap. This I fasten to the
upper sash. On the lower sash is fixed another plate carrying a catch, over
which the tongue or flap before mentioned passes by means of a slot formed
to receive it. The catch turns on a pivot or stud, and carries a small cam,

page_text: which when the fastener is turned presses against the inside of the metal
tongue, thereby bringing the two sashes together so as to make a close joint.
By this means I obtain a firmer fastening, avoiding any vibration of the
window frames, and at the same time rendering it impossible to slide it back
from the outside of the window.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard William Pyne in the Great Seal Patent Office on
the 10th June 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
WILLIAM PYNE, of Grove Lane, Camberwell, in the County of Surrey,
Builder, send greeting.
WHEREAS Her 'most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of December, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Richard William Pyne, Her special licence that I, the said Richard
William Pyne, my executors, administrators, and assigns, or such others as
I, the said Richard William Pyne, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and lawfully
might make, usa, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "AN IMPROVED SASH OR SHUTTER FASTENER, ALSO APPLICABLE TO DOORS AND
CASEMENTS," upon the condition (amongst others) that I, the said Richard
William Pyne, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Richard William Pyne, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say:--
My Invention relates to an improvement in the fastenings of window sashes,

page_text: shutters, doors, casements, and similar articles. I make use of a metal plate,
attached to which by a hinge is a tongue or flap.. This I fasten to the upper;
sash. On the lower sash is fixed another plate carrying a catch, over which the
tongue or flap, before mentioned passes by means of a slot formed to receive it.
The catch turns on a pivot or stud, and is arranged so that it has the same
action as an excentric or cam, and when turned so as to secure the casement
presses at the same time tightly against the inside of the tongue or flap, thus
bringing the sashes together and making a close joint, preventing all vibra-
tion of the windows, and rendering it impossible to slide it back from the
outside of the window.
In order more clearly to illustrate the above description, I have to this
Specification appended the accompanying Drawings, which are intended to
shew the main principle of my Invention, it being understood that modifica-
tions of the same may be adopted to suit particular circumstances.
Figure 1 is a side elevation of my improved window fastener, shewing the
fastener closed; Figure 2 is a similar view, shewing the fastener open; Figures
3 & 4 are plans of the fastener, shewing the different positions of the catch;
Figure 5 is a plan, shewing the application of my improved fastener to a
French casement; Figure 6 is a side view, shewing the hinge of the metal
flap, and the form I prefer when used for French casements. Similar letters
indicate the same or similar parts in the different Figures.
a, a, are the plates, preferably metallic, to one of which is attached the
flap b. This flap works on a hinge c, which is formed with a stop d, thus pre-
venting the flap going back too far. The other plate carries the catch e,
which works on a center at f (see Figures 3, & 4.) It will be seen that by
this means I tighten the fastener, as when the catch e is turned in the position
(see Figure 3) the front of it presses against the inside of the slot, which
forces the sashes g, g, close together, thus effectually preventing any rattling
or noise of the frames against one another. In Figure 5 the fastener is
shewn as applied to a French casement. It will be seen that the position is
changed alone, the fastener being turned round, so that the catch e does not
fall down and allow the window to open, the parts remain the same with the.
exception of the hinge of the flap, which I prefer without the stop d, so that
the flap can be put or turned right back.
Having now described the nature of my Invention, and how the same is
formed and acts, I wish it understood that what I claim, and desire secured
to me by the before in part recited Letters Patent, is, the use, construction,
and application of a window fastener to windows, doors, and casements, sub-

page_text: stantially as herewithin described and set forth, and more fully illustrated in
the accompanying Drawings.
In witness whereof, I, the said Richard William Pyne, have hereunto
set my hand and seal, this Tenth day of June, in the year of our
Lord One thousand eight hundred and sixty-four.
RICH. W. PYNE. (L.S.)
