and grant unto me, the said John Woollright, Her special licence that I,
the said John Woollright, my executors, administrators and assigns, or
such others as I, the said John Woollright, 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, usc, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "AN IMPROVED WINDOW SASH FASTENER," upon tho
condition (amongst others) that I, the said John Woollright, my exe-
cutors or administrators, by an instrument in writing under my, or
their, or one of their hands and scals, 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 calender months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Woollright, do hereby declare
the nature of my said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the
following statement :-
My Invention for an improved window sash fastener consists of an
adjustable stud, which is countersunk into the window frame and presses
against the window sash, the pressure being applied by an adjusting
screw. This screw revolves freely in a plate, which is screwed or other-
wise attached to the window frame. The stud is made square, with the
screw passing through its centre. The screw is fitted with a suitable
thumb and finger piece, so that it can easily be turned and adjusted by
hand, the action being that as the screw is turned the stud is pressed
against the window sash or withdrawn at option and as necessary, the
result obtained being that when the stud is pressed against the window
sash the sash is kept steady and will not rattle or shake with high winds
or sudden draughts, and when the stud is withdrawn or unscrewed, the
sash is free to slide up or drown.
One, two, or more fasteners may be used to steady each sash, and
being countersunk in the frame they are fixtures and always ready
for use.
The before-going being the nature, object, and purposes of this my
Invention, I will now proceed to describe more in detail how the same may
be carried out into practical effect, and for that purpose I have hercunto
attached a Sheet of Drawings illustrative of my Invention, marked with
letters and figures of reference corresponding with those in the following
explanation. Like letters and figures denote similar parts in the various
views.
Figure 1 is a sectional clevation; Figure 2, an outside clevation;
Figure 3, a bottom view; and Figure 4, a top view of same.
Upon reference it will be seen that my improved window sash fastener
consists of an adjustable stud a, which is countersunk into the window
frame A, and presses against the window sash B, the pressure being
applied by an adjusting screw b. The screw 6 revolves freely in the
plate c, which is screwed or otherwise attached to the window frame A.
The stud a is made square, with the screw b passing through its centre.
The screw is fitted with a thumb and finger piece d, so that it can
casily be turned and adjusted by hand, the action being that as the
screw is turned the stud a is pressed against the window sash B or
withdrawn at option and as necessary, the result obtained being that
'

page_text: when the stud a is pressed against the window sash B the sash is kept
steady and will not rattle or shake with high winds or sudden draughts.
When the stud is withdrawn or unscrewed the sash B is free to slide up
and down.
One, two, or more fasteners may be used to steady each sash, and 5
being countersunk in and screwed to the window frame A they are
fixtures and always ready for use.
Having thus stated the construction and mode of operation of my
Invention, and how the same may be carried out into practical effect, I
claim as the Invention secured to me by Letters Patent as aforesaid, the 1
adjustable stud a, screw b, and plate c in combination, forming a window
sash fastener, substantially as set forth.
In witness whereof, I, the said John Woollright, have hereunto set
my hand and seal, this Twenty-fifth day of June, in the year of
our Lord One thousand eight hundred and seventy-three.

Witness,
JOHN (L.s.) WOOLLRIGHT.
