PROVISIONAL SPECIFICATION left by the said Edward Jackson Emmons
at the Office of the Commissioners of Patents, with his Petition, on the
1st December 1856.
I, EDWARD JACKSON EMMONS, of the State of Massachusetts, of the United
States of America, do hereby declare the nature of the said Invention of
"A NEW OR IMPROVED NURSERY CHAIR," (the same having been communicated
to me by one Joshua Stevens, residing in the said United States,) is fully set
forth in the following Specification, and the accompanying Drawing, which
shows a perspective view of the same, that is to say:-
It consists of a chair for exercising a child or infant, and is composed, first,
of a frame A, and a seat, platform, or secondary chair B, suspended within
the frame A, and by means of springs b, b, so arranged, that when the child is
sitting upon the seat B he will be supported by means of it and the suspension
springs, and while his feet rests on a bar c attached to the chair frame A, he,
by pressure of them on the said bar, so as to raise himself, and subsequently,

page_text: by throwing his weight on the seat, may produce vertical motions of the seat
and himself, that may be sufficient to amuse and exercise him.. There may
be attached to the frame A a scale, which, with an index pointer, extended
from the frame B, may serve to indicate the weight of the child.
I do not claim arranging the seat of a chair on springs as usually
applied, but I claim the nursery chair as constructed, with its parts arranged,
and operating essentially, as described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Jackson Eminons in the Great Seal Patent Office
on the 3rd April 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
JACKSON EMMONS, of the State of Massachusetts, of the United States of
America, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of December, A.D. 1856, in the twentieth
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Edward Jackson Emmons, Her special license that I, the
said Edward Jackson Emmons, my executors, administrators, and assigns, or
such others as I, the said Edward Jackson Emmons, my executors, administra-
tors, 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, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention of "A NEW OR IMPROVED NURSERY CHAIR," (the same having been
communicated to me by one Joshua Stevens, a resident of the said State of
Massachusetts), upon the condition (amongst others) that I, the said Edward
Jackson Emmons, by an instrument in writing under my hand and seal, 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 Edward Jackson Emmons, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and represented in and by
the following Specification, and the accompanying Drawings, of which,
Figure 1 exhibits a front elevation of my said chair; Figure 2;. a side

page_text: elevation of it; Figure 3, a vertical and central section of it; and Figure 4,
a transverse section of it.
The nature of my Invention consists in a chair for exercising a child or
infant, and is composed, first, of a frame A, and a seat, platform, or secondary
chair B, suspended within the frame A, and by means of springs b, b, so
arranged, that while the child is sitting upon the seat B he will be supported
by means of it and the said suspension springs, and while his feet rests on a
bar c, attached to the chair frame A, he by pressure of them on the said bar
so as to raise himself, and subsequently by throwing his weight on the seat,
may produce vertical motions of the seat and himself, that may be sufficient to
exercise and amuse him. There may be attached to the frame A a scale,
which, with an index pointer extended from the frame B, may serve to
indicate the weight of the child.
I do not claim arranging the seat of a chair on springs as usually applied,
but I claim the nursery chair as constructed, with its parts arranged, and
operating esscutially as described.
In testimony whereof, I have hereunto set my signature and seal, this
Sixteenth of February, A.D. 1857.
