IMPROVEMENTS IN RAILROADS AND IN THE CARRIAGES TO BE USED THEREON
Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEROME
DEVILLE, of Crutched Friars, in the City of London, Coach Builder, 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 Third day of November, in the second year of Her reign,
did, for Herself, His heirs and successors, give and grant unto me, the said
Jerome Deville, Her especial licence, full power, sole privilege and authority,
that I, the said Jerome Deville, my exors, admors, and assigns, or such
others as I, the said Jerome Deville, my exors, admors, or 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 "IMPROVEMENTS IN RAILROADS AND IN THE
CARRIAGES TO BE USED THEREON;" in which said Letters Patent is contained a
proviso that I, the said Jerome Deville, shall cause a particular descrip-
tion 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
Jerome Deville, do hereby declare the nature of my Invention, and the manner

page_text: in which the same is to be performed, are fully described and ascertained
in and by the following statement thereof (that is to say):
These vehicles (somewhat like those employed on common roads) are built
to run on all curves whatever. The wheels, contrary to those now used on
railways, are at liberty, on the arms of the axletrees, and the axletrees are
applied to the carriage in such manner as to allow of movement so to allow
their turning to the straight direction of the road, as in the following descrip-
tion. The fore and hind carriage being similar to each other, each axletree
has a pole bolt, thus giving liberty of turning horizontally on that bolt. The
perch uniting the fore and hind carriage has two spring beds, on the middle
of which are adapted the heads of the pole bolts, going through the perch.
The vehicles are united by a rigid rod or pole run through on one end by the
hind pole bolt of the first coach, and on the other end by the fore pole bolt of
the following. From the first axletree the symmetrical direction is given to
the second axletree of the same carriage by means of a crossed chain or rope
passing round two pulleys or circles of the same diameter fixed on each axle-
tree. The motion from the first to the second vehicle being obtained by the
rigid rod or pole (uniting the carriages, as explained above), the direction is
given to the first axletree to the second carriage by a crossed chain or rope
which passes on one side round a pulley or circle fixed to the perch of the
first carriage, through which the pole bolt of the hind part is adapted, and on
'the other side on a pulley or circle fixed in the front axletree of the following
carriage. This pulley fixed on the axletree has the double diameter of the
other which is on the perch, and thus from axletree to axletree and from one
vehicle to another. In case of heavy loads, such as those of locomotives, for
instance, the centre of the circle should be supported by a third axletree fixed
in the middle of the carriage, borne on two wheels without flanges, the width
of which should be calculated according to the smallest curve that is to be run
The front axletree of the first coach, in case one should give up the
idea of having it directed by a conductor," might receive the direction from the
road itself. One of the means to be employed is to fix at each end of that
axletree between the wheels a fork, the heads of which descending to the
brim of the rails would bear four small wheels, which, on merely touching
them, would give to that axletree without any violence the perpendicular
direction to the road.

In witness whereof, I, the said Jerome Deville, have hereunto set my
hand and seal, this 30th day of November, One thousand eight hundred
JEROME DEVILLE. (L.S.)
