Year: 1843

page_text: BOYDELL'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
BOYDELL, junior, of Oak Farm Iron Works, near Dudley, Ironmaster, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Seventeenth day of February, in the sixth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
James Boydell, Her especial licence, full power, sole privilege and authority,
that I, the said James Boydell, my exors, adiñors, and assigns, or such, others
as I, the said James Boydell, my exors, adñors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the term
exercise,
of years therein expressed, should and lawfully might make, use,"
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVEMENTS IN APPARATUS FOR. RETAINING THE WHEELS OF
CARRIAGES IN THE EVENT OF AN AXIS BREAKING OR OTHERWISE;" in which said
Letters Patent is contained a proviso, that I, the said James Boydell, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, 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
James Boydell, do hereby declare that the nature of my Invention, and the
manner in which the same is to be performed; are fully described and ascer-
tained in and by the following statement thereof, reference being had to the

page_text: Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say):
=
My Invention relates to certain apparatus combined with the use of such
description of axles as run from side to side of the carriages to which they are
applied, each axle having two wheels affixed or turning thereon, and this appa-
ratus is so arranged as to prevent the wheels getting away when any of the
axes break, and also prevent the wheels coming off the axes in the event of
linch-pins or other fastenings coming out.
DESCRIPTION OF THE DRAWING.
Figures 1 and 2 represent one arrangement of the apparatus, used in com-
bination with an axle of a carriage having two wheels revolving thereon; and
it will be seen that the apparatus a, a, is so formed as to come on either side
of the wheel, but allowing the wheel to turn freely between the parts a, a,
such parts a, a, being affixed in any convenient manner. Figures 3 and 4
show a variation of the apparatus to render it fit for a railway carriage, each
wheel having applied thereto the apparatus shown in the Drawing. It will be
seen that the apparatus shown at Figures 3 and 4 embrace, though the parts
do not touch, the periphery of the wheel at four places, as marked 1, 2, 3, 4.
The object is to retain the wheel notwithstanding the much greater weight of
a railway carriage. It will be evident that, on the one hand, the wheels
cannot come off the axes, and, on the other hand, if either axis breaks, the
upper parts of the apparatus would fall on to the upper part of the wheel,
and the carriage would be upheld; and in the case of Figures 3 and 4,
the wheel would be prevented strutting outwards by the parts of the appa-
ratus a, a, at (3) and (4), and such parts (3) and (4) may, if desired, be used
in all cases for greater safety, but I have not found them necessary in light
carriages.
Having thus described the nature of my Invention, and the best means I am
acquainted with for performing the same, I do not confine myself to the precise
forms shown, nor to the details of fixing the apparatus, so long as the peculiar
character of my Invention be retained. But what I claim is, the mode of
applying apparatus a, a, in combination with axles of carriages, where each
axle passes from side to side of the carriage, and has two wheels affixed or
turning thereon, as above described.
In witness whereof, I, the said James Boydell, have hereunto set my
hand and seal, this Fifteenth day of August, in the year of our Lord
One thousand eight hundred and forty-three.
JAMES (L.B.) BOYDELL, JUN³.
