CERTAIN IMPROVEMENTS IN THE AXLETREE OF CARRIAGES
Year: 1810

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I; JONATHAN
VARTY, of Liverpool, in the County of Lancaster, Coach Maker, do send
greeting.
WHEREAS His most Excellent Majesty George the Third, by His Letters
Patent under the Great Seal of the United Kingdom of Great Britain and
Ireland, bearing date at Westminster, the Seventeenth day of September, now
last
past, did give and grant unto me, the said Jonathan Varty, my executors,
administrators, and assigns, His special licence, full power, sole privilege and
authority, that I, the said Jonathan Varty, my, executors, administrators, and
assigns, should and lawfully might, during the term of years therein expressed,
make, use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN THE AXLETREE OF
CARRIAGES;" in which said Letters Patent there is contained a proviso, obliging
me, the said Jonathan Varty, under my liand and seal to cause a particular
description of the nature of my said Invention, and the manner in which the
same is to be performed, to be inrolled in His Majesty's High Court of Chancery
within two calendar months next and immediately after the date of the said
recited Letters Patent, as in and by the same, relation being thereunto had,
may more. fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Jonathan Varty, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is fully described and
ascertained as follows (that is to say):-
-
In making the arm of the axletree, I divide the bottom half of the axletree
into several parts, according to tlie weight intended to be carried; I then cut
out of the two upper thirds, supposing the under half to be divided into three

page_text: parts, sufficient to take the bearing of those parts, so that the friction and
weight rest only on the sixth part of the axletree; the bearing part I leave
larger or smaller agreeably to the weight intended to be carried. In some
cases I fix small rollers, two or more, as occasion may require, in recesses cut
for that purpose in the bottom of the axletree. These rollers turn on their
own axes in pieces of steel or any other hard metal also fixed in the said
⚫ recesses. In this case the bottom of the axletree must be flattened in order
to throw the weight on the rollers. I then make a groove, the length of the
arm on the top side, with small holes through the axletreo to admit of oil
flowing through to supply the axes of the rollers with sufficient moisture. In
this case the box or brush must be made with a cap at the point or shoulder,
or with caps both at the point and shoulder to contain oil, as is frequently
practised on different principles; or I supply the axletree with oil through a
pipe introduced through the shoulder waster, at the upper end of which pipe I
screw a can, cap, or hollow ball to contain oil. These several improvements
may be used either separately or collectively. In cases where the box or brech
is a fixture, instead of cutting away the axletree, I make the alteration in the
bottom half of the box in the same way as described for the axle tree. When
horizontal axletrees are used, the arm of the axletree should be of the same
size at the point as at the shoulder, and the wheel made perfectly upright
without any dish.
In witness whereof, I, the said Jonathan Varty, have hereunto set my
hand and seal, this
day of November, in the year of our
Lord One thousand eight hundred and ten
Inrolled the Seventeeth day of November, One thousand eight hundred
and ten.
