IMPROVEMENTS IN SASH FASTENINGS
Year: 1861

page_text: LETTERS PATENT to William Farlar, of Turnham Green, in the County
of Middlesex, for the Invention of "IMPROVEMENTS IN SASH FASTENINGS,
Sealed the 11th March 1862, and dated the 18th September 1861.
PROVISIONAL SPECIFICATION left by the said William Farlar at the
Office of the Commissioners of Patents, with his Petition, on the 18th
September 1861.
'I, WILLIAM FARLAR, of Turnham Green, in the County of Middlesex, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN SASH
FASTENINGS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO OTHER PURPOSES," to
be as follows:-
My improvements in sash fastenings consist in forming the ordinary lever
catch (which is fastened on the upper sash) with a projection or stud, by
preference, of a V or diamond shape, which (when the lever is moved under
the locking plate) comes in front of an arm, carried by a screw nut on a
thumb-screw attached to the lower sash, so that by turning the screw a V or
other shaped recess on the arm acts on the V or other shaped stud on the
lever, and thus draws and secures the two parts of the window firmly together,.
by which all noise from the shaking of the parts will be prevented, and such
fastenings will be more secure from being unfastened from the outside than
heretofore.

page_text: Fastenings constructed according to my Invention may be applied to
windows of other descriptions where fastenings are required, and such
fastenings may be applied to dining tables, or for other purposes whero parts
require to be secured together and tightened at the samo time.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Farlar in the Great Seal Patent Office on the
13th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FARLAR, of Turnham Green, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of September, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Farlar, Her special licence that I, the said William
Farlar, my executors, administrators, and assigns, or such others as I, the
said William Farlar, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN SASH FASTENINGS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO OTHER
PURPOSES," upon the condition (amongst others) that I, the said William
Farlar, 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 William Farlar, do liereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed,
that is to say:
My improvements in sash fastenings consist in forming the ordinary lever
catch (which is fastened on the upper sash) with a projection or stud, by
preference, of a V or diamond shape, which (when the lever is moved under

page_text: the locking plate) comes in front of an arm carried by a screw nut on a
thumb screw attached to the lower sash, so that by turning the screw a
V or other shaped recess on the arm acts on the V or other shaped stud on
the lever, and thus draws and secures the two parts of the window firmly
together, by which all noise from the shaking of the parts will be prevented,
and such fastenings will be more secure from being unfastened from the
outside than heretofore.
Figure 1 of the accompanying Drawings is a plan of a fastening constructed
according to my Invention, showing it applied to a window. a is part of the
bottom rail of the upper sash, and a' is part of the top rail of the lower sash;
b is the lever catch on the upper sash rail a; c is the locking plate on the
lower sash rail a'; d is an arm, through which a screw e passes, and along
which it is free to travel. To secure the sash, pull the lever catch 6 over the
sash rail a' and beneath the arm d, turn the thumb-piece f of the screw e
until the arm & abuts against the stud g on the lever catch, when the sash
bars a and a will be drawn close together, and the catch at the same time
secured, as shown in Figure 2. To loosen the fastening, turn the screw e in
the reverse direction until the arm d abuts against a lug h at the termination
of the screw; the point of the arm then rises, and the lever catch 6 may
be pushed back to the position shown in Figure 1.
Fastenings constructed according to my Invention may be applied to sashes
of any construction where fastenings are required, and also to dining tables,
and for-other purposes where parts require to be secured together and tightened
at the same time.
And having now described the nature of my said Invention, and in what
manner the samo is to be performed, I declare that I claim the construction
of sash and other fastenings with a screw and arm made to act on the lever,
substantially in manner herein-before described and illustrated in the accom-
panying Drawings.
In witness whereof, I, the said William Farlar, have hereunto set
.my hand and seal, this Thirteenth day of March, One thousand eight
hundred and sixty-two.
W. FARLAR. (LS.)
