IMPROVEMENTS IN TRACTION ENGINES AND BOILERS FOR TRACTION, LOCOMOTIVE, AND OTHER PURPOSES
Year: 1862

page_text: LETTERS PATENT to Joseph Lee and William Lee, of Humberstone
Road, Leicester, for the Invention of "IMPROVEMENTS IN TRACTION ENGINES
AND BOILERS FOR TRACTION, LOCOMOTIVE, AND OTHER PURPOSES."
Sealed the 27th March 1863, and dated the 4th October 1862.
PROVISIONAL SPECIFICATION left by the said Joseph Lee and William
Lee, at the Office of the Commissioners of Patents, with their Petition,
on the 4th October 1862.
We, JOSEPH LEE and WILLIAM LEE, of Humberstone Road, Leicester,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN TRACTION
ENGINES AND BOILERS FOR TRACTION, LOCOMOTIVE, AND OTHER PURPOSES," to be as
follows:-
This Invention has for its object improvements in traction engines, and in
boilers for traction, locomotive, and other purposes. The improvements in
traction engines consist in giving motion to the main or driving pair of wheels
by a pinion on the crank shaft of the engine, gearing into an intermediate
wheel, on the axis of which is another smaller wheel which gears into a toothed
wheel on the axis of the main or driving wheels. The intermediate wheels
turn on a stud which projects from the bracket which carries the crank shaft,
this stud, the crank shaft, and the axis of the main wheels are so placed that
their centres are all in one vertical line. In place of the above combined
arrangement two driving wheels are placed under the body part of the

page_text: boiler, and upon the axle of the said wheels two cog wheels are placed
one on one side of the boiler and the other on the other side thereof. In
order to give motion to the cog wheels a shaft is applied under the body of
the boiler parallel with the axle of the driving wheels. On this shaft are
applied pinions for fast and slow speeds. A chain and chain wheels are also
applied between the crank shaft and the lower shaft in order to give motion
from the crank shaft to such lower shaft. Or an inclined shaft and bevil
gear may be used instead of the chain to connect the shafts. This arrange-
ment admits of steel or india-rubber springs being applied with advantage.
The improvements in boilers for traction, locomotive, and other purposes,
consist in constructing them so that the horizontal tubes which pass from the
fire-box conduct the products of combustion into a smoke box or chamber
from the top of which they pass away through vertical tubes which rise up
through the dome or steam chamber of the boiler, and on the exterior of the
dome the tubes open into a chimney which can be turned down when the tube
requires cleaning. The smoke box or chamber above mentioned is formed by
the plate which receives the ends of the horizontal tubes from the fire-box
being bent at right angles, the portion bent down at right angles receiving
the vertical tubes which rise up through the dome.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Lee and William Lee in the Great Seal Patent
Office on the 4th April 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
LEE and WILLIAM LEE, of Humberstone Road, Leicester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of October, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Joseph Lee and William Lee, Her special licence that we,
the said Joseph Lee and William Lee,
and William Lee, our executors, administrators,
and assigns, or such others as we, the said Joseph Lee and William Lee,
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 "IMPROVEMENTS IN
TRACTION ENGINES AND BOILERS FOR TRACTION, LOCOMOTIVE, AND OTHER PURPOSES,"
upon the condition (amongst others) that we, the said Joseph Lee and William
Lee, our executors or administrators, by an instrument in writing under
our or their hands and seals, or under the hand and seal of one of us or
them, 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 Joseph Lee, on behalf of myself and the
said William Lee, do hereby declare the nature of the said Invention, and
in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, that is to say :-
This Invention has for its object improvements in traction engines, and in
boilers for traction, locomotive, and other purposes. The improvements in
traction engines consist in giving motion to the main or driving pair of wheels
by a pinion on the crank shaft of the engine gearing into an intermediate
wheel on the axis of which is another smaller wheel which gears into a toothed
wheel on the axis of the main or driving wheels. The intermediate wheels
turn on a stud which projects from the bracket which carries the crank shaft,
this stud, the crank shaft, and the axis of the main wheels are so placed that
their centres a 9 all in one vertical line. In place of the above combined
arrangement two driving wheels are placed under the body part of the boiler
and upon the axle of the said wheels two cog wheels are placed one on one
side of the boiler, and the other on the other side thereof. In order to give
motion to the cog wheels a shaft is applied under the body of the boiler
parallel with the axle of the driving wheels. On this shaft are applied
pinions for fast and slow speeds.
A chain and chain wheels are also applied
between the crank shaft and the lower shaft in order to give motion from
the crank shaft to such lower shaft. Or an inclined shaft and bevil gear may
be used instead of the chain to connect the shafts. This arrangement admits
of steel or india-rubber springs being applied with advantage.
The improvements in boilers for traction, locomotive, and other purposes,
consist in constructing them so that the horizontal tubes which pass from the
fire-box conduct the products of combustion into a smoke box or chamber,
from the top of which they pass away through vertical tubes which rise up
through the dome or steam chamber of the boiler, and on the exterior of the
dome the tubes open into a chimney which can be turned down when the

page_text: tubes require cleaning. The smoke box or chamber above mentioned is
formed by the plate which receives the ends of the horizontal tubes from the
fire-box being bent at right angles the portion bent down at right angles
receiving the vertical tubes which rise up through the dome.
In witness whereof, I, the said Joseph Lee, have hereunto set my
hand and seal, this Fourth day of April in the year of our Lord One.
