Year: 1831

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
COCHRANE, of Norton Street, Great Portland Street, in the county of Middlesex,
Esquire, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Tenth day of August, in the second year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Alexander Cochrane, His especial licence, sole privilege and authority, that I,
the said Alexander Cochrane, my exors, admors, and assigns, or such others
as I, the said Alexander Cochrane, my exors, admors, and assigns, should
at any time agree with, and no others, from time to time and at all times
during the term of years therein mentioned, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN MACHINERY FOR
PROPELLING OR MOVING LOCOMOTIVE CARRIAGES, AND GIVING MOTION TO MILLS AND
OTHER MACHINERY;" in which said Letters Patent is contained a proviso that
I, the said Alexander Cochrane, shall cause a particular description of the
nature of my said Invention, and in what manner the same is to be per-
formed, to be inrolled in His 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
Alexander Cochrane, do hereby declare that the nature of my said Invention,
and in what manner the same is to be performed, is particularly described and

page_text: ascertained by the following description thereof, reference being had to the
Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say) :-
The Drawing No. 1 is to show how the crank of an axletree fixed to a
wheel or wheels, No. 1 and 2, is acted upon by means of a lever or levers.
The person working at the lever a is seated, as in the position of rowing; see
Drawing No. 1. The lever a is connected to the crank 6 of the axletree by
means of a branch c. Before the crank of axletree, as well as behind,
levers can be attached by means of a branch, or branches, as in
Drawing No. 1; d the fulcrum to the levers. It is requisite that the man
seated shall have a foot board e, to press his feet against; each extra man will
have the same action to perform. The Drawings No. 1, 2, and 3, will show
how the axletree works in the box of the stay, (which is a part of the carriage
or machine, as well as in the box of carriage or fly-wheel. The axle, letter A,
works in box B, supported by the stay Z, z. A washer C is fastened on the
axle close to the box of stay B. From washer C to washer D is a space left for a
bolt E, which is to fasten the axletree to the stock of wheel F, or set it free by
means of a trigger G, which pushes the bolt backwards and forwards in order to
fasten or unfasten the axletree to the stock of wheel or wheels. The crank or
winch R of axle, Drawing No. 4, is connected to a handle S, by means of a branch
or branches T; the handle S is worked in a sliding groove u, backwards and
forwards by the man or men who are seated in the position of rowing a boat.
The mode of turning the locomotive carriage round on its own compass,
(which is done by taking the action off the inner wheel, and giving action to
the outer, I claim as part of my Invention. The method of working the lever
and crank No. 1 and 2, as well as the crank or winch with slide and handle,
when seated in the position of rowing, I claim as part of my Invention. The
system of employing several levers, to act by means of branches on the same crank
No. 1, I claim also as part of my Invention, as well as the plan of employing
one or more persons to work at the same crank or winch No. 4, by means of a
connecting rod or rods attached to the handle or handles which work in a
sliding groove. The person or persons working at it are seated, as in the
position of rowing, Drawing 1 and 4.
The Drawing No. 5 is to show how the action of the carriage, mill, or other
machinery to which my Invention is applicable, is to be increased by applying
an extra power to the axle and winch, which is acted upon by the lever or
levers, or crank or winch, Drawings 1, 2, 4, by having one brace or cog wheel
larger than the other, each being connected. The smaller brace or cog wheel
will go round faster in proportion to the speed of the larger cog wheel.

page_text: In applying it to locomotive carriages, I claim as part of my Invention. The
plan of taking the action or power off either wheel, and applying it when
required, is by fastening or unfastening the stock of the wheel to the axle, I
claim as part of my Invention, see Drawing No. 3.
In witness whereof, I, the said Alexander Cochrane, have hereunto set
my hand and seal, this Tenth day of February, One thousand eight
hundred and thirty-two.
Inrolled the Tenth day of February, in the year of our Lord One thou-
sand eight hundred and thirty-two.
