page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CAIRNCROSS, of Greek Street, Soho, in the County of Middlesex, Cabinet
Maker, sends greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date tlie
Nineteenth day of December, in the twenty-seventh year of His reign, did
give unto me, the said William Cairncross, His special licence that I,
the said William Cairncross, during the term of years therein expressed;
should and lawfully might make, use, exercise, and vend, within Eng-
land, Wales, and Town of Berwick-upon-Tweed, my Invention of "A
METHOD OF SECURING AND RENDERING STRONG AND PERMANENT THE TENANTS OR
JOINTS BETWEEN THE LEGS AND RAILS OF CHAIRS AND TABLES, &C., IN CABINET
WORK, BY MEANS OF SCREWS MADE OF IRON, BRASS, OR ANY OTHER METAL OR MIXED
METALS, AND INTERNALLY APPLIED WITHOUT BEING SEEN OR DISCERNABLE ON THE
OUTSIDE OF ANY WORK WHEREON OR WHEREUNTO THE SAID METHOD IS APPLICABLE;"
in which said Letters Patent is contained a provisoe obliging me, the said.
William Cairncross, under my hand and seal, to cause a particular descrip-
tion of the nature of my said Invention, and how the same is to be performed,:
to be inrolled in His Majesty's High Court of Chancery within one calendar
month next after the date of the said recited Letters Patent, as in and
by the same (relation being thereunto had) will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said provisoe, I, the said
William Cairncross, do hereby declare that my said Invention of a Method

page_text: of Securing and Making Strong and Permanent the Tenants or Joints between
the Legs and Rails of Chairs and Tables, &c., in Cabinet Work, by means of
Screws made of Iron, Brass, or any other Metal or mixed Metals, and inter-
nally applied without being seen or discoverable on the Outside of any Work
wherein or whereunto the said Method is applicable, is described in manner
following, that is to say :-
The principle, utility, and advantages of the said Invention arises from an
application of bolts or pins made of iron, or any other metal or mixed metal,
in a concealed manner, in the legs and rails of chairs, tables, and other kinds
of cabinet work, and work of that nature, which bolts or pins are so con-
trived as to be easily drawn by screwed nutts or wedges to any required degree
of tightness, so as to strengthen, combine, and render permanent, with or
without glue, the joints between the legs and rails of such work, whereby all that
kind of furniture will be rendered much more serviceable, being always found
first to fail or give way in those parts by reason of those parts having to sustain
the greatest stress, and on account of the decay of glue, the shrinking of
the wood, &c., each of which leaves the said articles totally useless.
This Invention will likewise be of singular utility in the fabrication of
cabinet or other goods intended for exportation, as they can easily be taken to
pieces and be put together by a person no ways skilled in mechanics, and are
thereby rendered much more portable and convenient, and which bolts or pins
are made after the manner described and shewn in the Drawings herein made
and herein-after referred, that is to say:-
The Drawing, Fig. 1, represents the iron work for all sorts of square and
bevil'd angles to be tightened with screwed nutts. A is one of the bolts or
pins made somewhat broad and flatt at one of it's ends, into which end the
bolt or pin B is fastened by being screwed or otherwise; C, C, are the two
nutts which tighten the bolts when fixed in the work. Fig. 2 represents the
iron work when fixed in a frame. A is the plan of a leg of a chair, table, &c. ;
B, B, the nails. Fig. 3 represents a circular bolt, which will answer all work
of that kind. Fig. 4 is a section of a foot and rail. A, the foot; B, the rail;
the dotted line C is the tenant; D, the square hole cut out of the rail to let
the key or winch get in to turn the nutts.
In witness whereof, I, the said William Cairncross, have hereunto set
my hand and seal, the
