Year: 1852

page_text: LETTERS PATENT to James Hare, of Birmingham, in the County
of Warwick, for the Invention of "IMPROVEMENTS IN EXPANDING
TABLES AND IN MUSIC STOOLS."
Sealed the 13th January 1853, and dated the 1st October 1852.
PROVISIONAL SPECIFICATION left by the said James Hare at the
office of the Commissioners of Patents,. with his petition, on the
1st October 1852.
I, JAMES HARE, of Birmingham, in the County of Warwick, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
EXPANDING TABLES AND IN MUSIC STOOLS" to be as follows:-
This Invention consists,-First, of causing toothed racks, which are
fixed to parts of a table, to be moved in opposite ways by right and left
bonded screws, put in motion by a key or bar sliding within the axis
of the screws; and secondly, my Invention consists of using a long
screw nut in a music stool, and using a short screw with a stem or axis
which passes above and below through collars, and is fixed to the seat
by a plate and screws at top.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said James Hare, in the Great Seal Patent Office, on
the 1st April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JAMES HARE, of Birmingham, in the County of Warwick, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of October in the year of our
Lord One thousand eight hundred and fifty-two, in the sixteenth year
of Her reign, did for Herself, Her heirs and successors, give and grant
unto me, the said James Hare, Her special licence that I, the said
James Hare, my executors, administrators, and assigns, or such others
as I, the said James Hare, 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, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN EXPANDING TABLES AND IN
MUSIC STOOLS," upon the condition (amongst others) that I, the said
James Hare, 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 in compliance with the said proviso, 1, the
said James Hare, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof; reference
being had to the drawings hereunto annexed, and to the figures and
letters marked thereon, that is to say:
My Invention consists,-First, of causing toothed racks, which are
fixed to parts of a table, to be moved in opposite ways by right and left
-handed-screws, put in motion by a key or bar sliding within the axis of
the screws; and,

page_text: Secondly, my Invention consists of using a long screw nut in a
music stool, and using a screw with a stem or axis which passes above
and below through collars, and is fixed to the seat by a plate and
screws at top.
And in order that my said Invention may be most fully understood
and readily carried into effect, I will proceed to describe the means
pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1, shows the combined apparatus complete; Figure 2, shows
the bar (by preference of a square section) which slides within the
axis (which has a left and right handed screw formed or fixed thereon),
such bar having combined with it one of the racks, and one of the
plates by which the apparatus is affixed to the parts of a table. Figure 3,
shows the hollow spindle, with its left and right hand screws formed or
aflixed thereon; and Figure 4, shows the apparatus fixed to parts of a
dining table. In each of these Figures the same letters of reference are
used to indicate the same parts; a, is a square bar having a square
end at a', on to which may be placed a moveable key, to turn it; this
bar a, turns in its plate b, which is fixed to part of the framing of the
table; d, is a rack, in the teeth of which the screw g, on the hollow
spindle c, gears, and by which that rack d, is moved into or from the
frame e, e, f, f; the bar a, sliding into or out of the hollow spindle c,
according as the bar a, is turned in one direction or the other; and the
rack d, slides in a groove formed in the frame f. The other screw h, on
the hollow axis c, gears into the teeth of the other rack d, which is fixed
to the other plate b, and slides in a groove in f; and as the screws are
right and left, the two racks d, will be moved in opposite directions,
whether when contracting or expanding the table to which the apparatus
is applied.
I will now proceed to describe the second part of my Invention, which
relates to music stools. Figure 5, shows the combined apparatus, partly
in section. Figure 6, shows the long screw nut with the collars top and
bottom for guiding the spindle. Figure 7, shows the spindle, to which
the seat is affixed separately; a, is the spindle, having a plate and screw
at its upper end, to which the seat is fixed by screwing. And it will be

page_text: found, that by means of the screw and plate the seat will be more firm
than by the means of fixing heretofore resorted to, and the spindle has
also thereon a short screw, a', by which it is caused to rise and fall in
the fixed nut b, according as the spindle is turned in one or other
direction; c, c, are collars fixed at the two ends of the nut b, as shown.
The nut b, is fixed in the pedestal of the stool, and the seat is fixed to
the top of the spindle.
By this arrangement it will readily be understood, that the spindle, a,
will be retained and guided in a vertical position by the collars c, c, and
as they are at a considerable distance apart, an advantage is derived
from this mode of constructing and combining the parts over the mode
of construction heretofore practised, wherein the male screw on the
spindle was long working into a short female screw.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood, that what I claim is,―
First, the combination herein described, of mechanical parts applicable
to expanding tables; and,
Secondly, I claim the combination of mechanical parts as herein
explained, applicable to music stools.
In witness whereof, I, the said James Hare, have hereunto set
my hand and seal, this Twenty-first day of March in the year
of our Lord One thousand eight hundred and fifty-three.
JAMES HARE. (L.S.)
