IMPROVEMENTS IN THE CONSTRUCTION OF CHAIRS
Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
LANE COULSON, of Assington Hall, Assington, in the County of Suffolk,
Esquire, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-ninth day
of June, in the tenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Thomas Lane Coulson, my
exors, admors, and assigns, Her especial licence, full power, sole privilege
and authority, that I, the said Thomas Lane Coulson, my exors, adñors,
and assigns, or such others as I, the said Thomas Lane Coulson, my exors,
adors, or assigns, should at any time agree with, and no others, from time
to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN
THE CONSTRUCTION OF CHAIRS;" in which said Letters Patent is contained a
proviso that I, the said Thomas Lane Coulson, shall cause a particular
description of the nature of my said Invention, and in what manner the
same is to be performed, by an instrument in writing under my hand and
seal, to be inrolled in Her said Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Lane Coulson, do hereby declare that the nature of my said

page_text: ON OF THE DRAWING.
Figure 1 is a front view of a chair with a back constructed according to my
Invention; Figure 2 is a side view of the chair, showing the parts in the state
when not in use; and Figure 3 is a side view of the chair showing its action.
The chan shewn is an ordinary dining-room chair, but aim and other kinds
of chairs may be similarly constructed. The moveable portion of the back of
the chair consists of the side bars a, a, which are each capable of movement
on a neck or axis b, as shown; and to this part of the arrangement I make
no claim, as the same is similar to what has before been done. c and d are
two padded or stuffed surfaces, each of which has necks or axes which are
carned by the side bars a, a. Hence these surfaces can move with the side
bars a, a, and in addition thereto each of the surfaces c and d has independent
inovement on its own necks or axes. In constructing the parts c and d they
are to be so weighted as to hang in the position shewn at Figure 2 when the
chair is not in use, or when the back is not pressed on by the person sitting
in the chair. It will readily be understood, that when a person is sitting in a
chair constructed as above described, the more the head and shoulders are
pressed against the surface c the more will the surface & be pressed against
the back of the person, and the middle of the back of the person will thus
receive additional support in proportion as the part c is more and more
pressed on. e, e, are pegs for securing the back when not required for use in
the manner described.
Having thus described the nature of my Invention, and the manner m
which the same is to be performed, I would have it understood that I make
no claim to the parts of the chair which are well known, nor do I confine
myself to the details shewn, so long as the character of my Invention be
retained. But what I claim is the mode of constructing the backs of chairs,

he parts a, as herein described.
In witness whereof, I, the said Thomas Lane Coulson, have hereunto
set my hand and seal, this Thirty-first day of October, in the year of
our Lord One thousand eight hundred and forty-six.
THOS LANE (L.s.) COULSON.
AND BE IT REMEMBERED, that on the Thirty-first day of October, in
the year of our Lord 1846, the aforesaid Thomas Lane Coulson came before
our said Lady the Queen in Her Chancery, and acknowledged the Specifi-
cation aforesaid, and all and every thing therein contained and specified, in
form above written. And also the Specification aforesaid was stamped
according to the tenor of the Statute made for that purpose.
Enrolled the Twenty-ninth day of December, in the year of our Lord
One thousand eight hundred and forty-six.
