CERTAIN IMPROVEMENTS ON CASTORS FOR FURNITURE AND OTHER USEFUL PURPOSES
Year: 1827

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
BENJAMIN GEITENER, of Birmingham, in the County of Warwick, Brass-
founder, send greeting.
WHEREAS His present most Excellent Majesty George the Fourth, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirteenth day of December, One thousand eight hundred
and twenty-seven, in the eighth year of His reign, did, for Himself, His heirs
and successors, give and grant unto me, the said Frederick Benjamin
Geithner, His especial licence, that I, the said Frederick Benjamin Geithner,
my exors, admiors, and assigns, or such others as I, the said Frederick Ben-
jamin Geithner, my exors, adññors, and 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 "CERTAIN IMPROVEMENTS ON CASTORS FOR FURNITURE AND OTHER USEFUL
PURPOSES;" in which said Letters Patent is contained a proviso, obliging me,
the said Frederick Benjamin Geithner, by an instrument in writing under my
hand and seal, particularly to describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, and to cause the
same to be inrolled in His Majesty's High Court of Chancery within six
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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Frederick Benjamin Geithner, do hereby declare that the nature of my said
Invention consists in the pivot or pin generally used in the manufacturing of
castors, and which I make with a circular shoulder or segment of a ball, to
work in a corresponding cup or segment of a circle sunk in the top of the 5
horn or claw, and made of wrought or cast iron, steel, copper, brass, tin, or
any other metal or composition of metals applicable to the purpose, large
enough to give the horn or claw a sufficient bearing without the assistance
and quite independent of the bottom of the socket, into which the said pivot
or pin is firmly rivetted or otherwise fastened; or I sometimes reverse the 1
form of my said pivot or pin, and fasten it to the horn or claw, sinking the
cup or concavity into socket, by either of which means a more regular or
steady movement or action is effected for my pivot or pin. With the circular
or ball bearing being separate, and perfectly true and centrically finished, this
object is completely attained; and as, by the moving of any kind of furniture
where castors are used, the legs by their elasticity will in some measure
describe a circular motion, my circular or ball bearing is therefore intended to
assist the action of the castor in reference thereto.
These improvements in the shape and bearing of the pin or pivot are the
whole of what I claim as my own Invention, and which I apply to all sorts of
castors, of every shape, plain or ornamental, square or round sockets, claw
and plate castors of all descriptions, and of all materials whatsoever.
DESCRIPTION OF THE DRAWING
hereunto annexed, which I declare to be part of this Specification.
Figure I. shews a round socket castor complete on my principle. Figure 2,
a section of the socket, with the pivot or pin affixed thereto. Figure 3, the
horn or claw, with its concavity to receive the pivot or pin. Figure 4, pivot
or pin, with its convex or ball bearing. Figure 5 shews a round socket
castor complete, with pivot or pin reversed. Figure 6, a section of the socket
with pivot or pin affixed thereto, reversed. Figure 7 shews the pivot or pin
with its convex bearing reversed.
In witness whereof, I, the said Frederick Benjamin Geithner, have here-
unto set my hand and seal, this Third day of June, in the year of our
Lord One thousand eight hundred and twenty-eight.
FREDERICK BENJAMIN (L.S.) GEITHNER.
