CERTAIN IMPROVEMENTS IN THE MANUFACTURE AND CONSTRUCTION OF CABS, COACHES, PROVISIONAL SPECIFICATION
Year: 1867

page_text: LETTERS PATENT to John Day, of Manchester, in the County of Lancaster,
and William Dorber, of the same Place, for the Invention of "CERTAIN
IMPROVEMENTS IN THE MANUFACTURE AND CONSTRUCTION OF CABS, COACHES,
PROVISIONAL SPECIFICATION left by the said John Day and William
Dorber at the Office of the Commissioners of Patents, with their Petition,
on the 16th August 1867.
We, JOHN DAY, of Manchester, in the County of Lancaster, and WILLIAM
DORBER, of the same Place, do hereby declare the nature of the said
Invention for "CERTAIN IMPROVEMENTS IN THE MANUFACTURE AND CONSTRUCTION
OP CABS, COACHES, CARRIAGES, OMNIBUSES, AND OTHER SIMILAR VEHICLES," to be as
follows:-
Our Invention is designed for the purpose of constructing cabs, coaches,
omnibuses, and other similar passenger conveyances principally of metal
instead of wood, whereby great lightness, strength, durability, and economy of
cost are obtained.

page_text: The improvements consist in the employment and use of angle or T iron
or steel, or tubular iron or steel for the framework of such vehicles, and of
corrugated metal for the roof and floor, and of tubular metal for the shafts,
such framework being connected together by metal screw bolts or rivets, and
if required may be galvanized to prevent corrosion. After the framework
is thus formed panels or coverings of wood may be fitted thereto, or metal
plates may be used and the interstices filled with sawdust, cork, or other
non-conductors of sound.
A second part of the Invention relates to a peculiar arrangement of levers
for opening the doors of certain descriptions of "Hansom cabs," and consists
in the application of one rod turning on a pin in its centre to each door,
the opposite ends of such rods being connected by a jointed connecting rod,
the joint pin of which moves in a guide slot and is attached by a strap or cord
passing beneath the roof of the cab to a lever and handle over which the driver
has control, so that by pulling the handle both doors are opened simultaneously,
and an elastic spring is employed to draw back the handle and close the door.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Day and William Dorber in the Great Seal Patent
Office on the 14th February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
DAY, of Manchester, in the County of Lancaster, and WILLIAM DORBER, óf the
same Place, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of August, in the year of our Lord One
thousand eight hundred and thirty-first, in the sixty-seven year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John Day and William Dorber, Her special license, that we, the said John
Day and William Dorber, our executors, administrators, and assigns, or such
others as we, the said John Day and William Dorber, our executors,
administrators, and assigns, should at any time agree with, and no. others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "CERTAIN IMPROVEMENTS IN THE MANUFACTURE
AND CONSTRUCTION OF CABS, COACHES, CARRIAGES, OMNIBUSES, AND OTHER SIMILAR

page_text: VEHICLES," upon the condition (amongst others) that we, the said John Day and
William Dorber, our executors or administrators, by an instrument in writing
under our, or one of our or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Day, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
Our Invention is designed for the purpose of constructing cabs, coaches,
omnibuses, and other similar passenger conveyances principally of metal instead
of wood, whereby great lightness, strength, and durability and economy of cost
are obtained.
The improvements consist in the employment and use of angle or T iron
or steel, or tubular iron or steel for the framework of such articles, and of
corrugated metal for the roof and floor, and of tubular metal for the shafts
and centre pillar in "Hansom cabs," such framework being connected together
by metal screw bolts or rivits, and if required the whole or part may be
galvanized or painted to prevent corrosion. The angle or T iron or steel is
first to be bent into the required form or lines required for the framework of
the vehicle, and where the said angle or T iron requires securing together or
to the roof or floor to construct the skeleton framework holes are drilled and
the parts are bolted or otherwise secured together with or without the
introduction of washers between the joints, and if necessary certain parts such
as angles may be strengthened by additional metal angle pieces. After
the framework is thus formed panels or coverings of wood may be fitted thereto,
or metal plates may be used and the interstices filled with sawdust, cork, or
other non-conductors of sound if necessary. In some descriptions of "Hansom
cabs "a front central pillar is used to which the two front doors are hinged, and
by the use of such pillar in the tubular form the door hinge plates may pass
into slots cut in the tube, and a solid pin or rod be passed down the tube to
form the hinge pin, thereby effecting a very firm hinge joint between the doors
and pillar.
We would here remark that since the filing of the Provisional Specification
for our said Invention we have ascertained that the second part of our
Invention as therein described is not so novel or original nor of such utility

page_text: as I then considered it to be, and we therefore hereby disclaim that portion
of the Invention.
In witness whereof, I, the said John Day, have hereunto set my
hand and seal, this Twelfth day of February, in the year of our Lord
One thousand eight hundred and sixty-eight.
Witnessed by
JOHN L. DAVIES,
