Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JoHN
LOACH, of Birmingham, in the County of Warwick, Brass Founder, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Fourteenth day of January, in the fourth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said John
Loach, my exors, adñññors, and assigns, Her especial licence, full power, sole
privilege and authority, that I, the said John Loach, my exors, adiñors,
and assigns, and such others as I, the said John Loach, my exors, and
assigns, should at any time agree with, and no others, from time to time and
at all times hereafter during the term of years therein mentioned, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN
CASTORS APPLICABLE TO CABINET FURNITURE AND OTHER PURPOSES;" in which
said Letters Patent there is contained a proviso that I, the said John Loach,
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 immediately after the date of
the said in part recited Letters Patent, as, upon reference thereunto, will
fully appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Loach, that the nature of my said Invention consists in the introduc-
tion of a horizontal anti-friction wheel between the horns and the bottom of
the estor, for the purpose of reducing the friction carrying the weight and
more effectually supporthe horns.
Figure 1, in the accompanying Sheet of Drawing, represents a side cleva-
tion; Figure 2, a front; and Figure 3, a back view of as improved castor.
A vertical and diametrical section of the same is shewn in Figare 4, and the
separate parts are illustrated by Figures 5, 6, 7, 8, 9, and 10. The same
letters of reference indicate in the various Figures the same parts, though. if-
ferently viewed. At a is the socket of the castor; 6 are its horns; a
the wheel; d is the horizontal anti-friction wheel introduced between the
bottom of the socket a and the horns b. On the front of the horns is situated
a circular projection e, which presses against the periphery of the anti-friction
wheel. This projection is distinctly shewn in elevation and section in
Figures 1, 2, and 4, and in Plan in Figure 10. f is the pin of the castor,
shown in section in Figure 4, and in elevation in Figure 8. g is a flange on
the pin, which is let into a recess h on the bottom of the castor. This recess
is seen in section in Figure 4, and in plan, Figure 9, which represents the
bottom of the socket of the castor. This pin, as seen in Figure 4, is rivetted
in the bottom of the socket a. Figure 8, A, is an elevation of the pin f, with
the anti-friction wheel & situated thereon. Figure 11 represents the applica-
tion of my improvement to plate castors a, the plate to be screwed to the
table or other furniture; c, a tube cast on the plate, into which the pinfis
rivetted; b, the horns; and e, the projection on the top of them; d, the anti-
friction wheel.
Having now described the nature of my said Invention, and the manner of
carrying the same into effect, I wish it to be distinctly understood that I do
not claim as of my Invention all the parts herein described; but I do claim
the introduction of an horizontal anti-friction wheel between the bottom of the
socket and the horns, which anti-friction wheel bears the weight upon the
castor and supports the horns by the projection on the latter bearing against
the periphery of the said anti-friction wheel. And this my Invention being
to the best of my knowledgo and belief entirely new in these kingdoms, I
hereby declare my intention to maintain an exclusive privilege for the
same.
As witness my hand and seal this Tenth day of July, in the year One
thousand eight hundred and forti and
JOHN (L.S.) LOACH.
