IMPROVEMENTS IN ENGINES FOR DRAWING OR CONVEYING HEAVY LOADS
Year: 1860

page_text: LETTERS PATENT to Alexander Chaplin, of Glasgow, in the County of
Lanark, North Britain, Engineer, for the Invention of "IMPROVEMENTS
IN ENGINES FOR DRAWING OR CONVEYING HEAVY LOADS."
Sealed the 10th July 1860, and dated the 18th January 1860.
PROVISIONAL SPECIFICATION left by the said Alexander Chaplin at the
Office of the Commissioners of Patents, with his Petition, on the 18th
January 1860.
I, ALEXANDER CHAPLIN, of Glasgow, in the County of Lanark, North
Britain, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN ENGINES FOR DRAWING OR CONVEYING HEAVY BODIES," to be
as follows, that is to say :-
This Invention consists, in the first place, in applying to self-propelling
traction engines mechanism for hauling forward the load by means of a rope
or chain. A simple mode of carrying out this improvement consists in arrang-
ing a winding barrel upon the axle of or in connection with the propelling
wheels of the engine; when the engine is unable to draw its load in the
ordinary way, in consequence, for example, of the road being up-hill, the
engine is moved on alone in advance, and the propelling wheels being raised
off the ground by means off crutches or otherwise, and the hauling rope
being connected to the load the engine is made to haul the latter up to it,

haul the load up to it. According to another modification, the winding barrel
and its gearing may be independent of the propelling wheels, in which case
these-will-not-require-to-be-raised off the ground when hauling is needed.
The Invention also relates to the constructing of engines to act either as
traction or hauling engines, or by carrying the load. To this end the frame
is made of extra length, one end or portion of it being intended for the load,
whilst the engine is mounted at the other end. It is preferred to arrange
and construct the engine and boiler details according to the plans or modi-
fication of the plans described in the Specifications of Letters Patents granted
to me, bearing dates respectively the 26th December 1857, No. 3165, and
the 7th April 1859, No. 866.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alexander Chaplin in the Great Seal Patent Office on the
16th July 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
CHAPLIN, of Glasgow, in the County of Lanark, North. Britain, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of January, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me
the said Alexander Chaplin, Her special licence that I, the said Alexander
Chaplin, my executors, administrators, and assigns, or such others as I, the
said Alexander Chaplin, my executors, administrators, or assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term thereinexpressed, 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 of "IMPROVE-
MENTS IN ENGINES FOR DRAWING OR CONVEYING HEAVY LOADS," upon the condition
(amongst others) that I, the said Alexander Chaplin, my executors or adminis-
trators, by an instrument in writing under my, 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.

page_text: NOW KNOW YE, that I, the said Alexander Chaplin, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol-
lowing statement in writing, that is to say:-
My said Invention consists in the first place in applying to self-propelling
traction engines mechanism for hauling forward the load by means of a rope
or chain. A simple mode of carrying out this improvement consists in
arranging a winding barrel upon the axle of or in connection with the
propelling wheels of the engine. When the engine is unable to draw its load
in the ordinary way, in consequence, for example, of the road being up-hill or
rough, the engine is moved on alone in advance, and the propelling wheels
being raised off the ground by means of crutches or otherwise, andthehauling
rope being connected to the load, the engine is made to haul the latter up to
it, whereupon it may, if required, move on a further stage in advance, and
again haul the load up to it. According to another modification, the winding
barrel and its gearing may be independent of the propelling wheels, in which
case these will not require to be raised off the ground when hauling is needed.
Thus if the winding barrel is retained upon the axle of the propelling wheels,
the latter may be driven by clutches capable of being thrown out of gear when
it is wished to wind up the hauling rope or chain without moving the carriage.
The winding barrel may, however, be arranged independently of the propell-
ing wheels or their axle, and ordinary clutches or frictional gear may be used
for working either independently. Instead of the engine being stopped
and hauling tho load up to it, the rope or chain may be carried forward and
fixed in advance, and the engine may be made to draw or haul itself, or
itself and the load, by means of the rope or chain so fixed.
My said Invention also relates to the constructing of engines to act either
as traction or hauling engines, or by carrying the load. To this end the
frame is made of extra length, one end or portion of it being intended for
the load, whilst the engine is mounted at the other end. It is preferred to
arrange and construct the engine and boiler details according to the plans
or modifications of the plans described in the Specification of Letters Patent
granted to me, and bearing dates respectively the 26th December 1857,
No. 3165, and the 7th April 1859, No. 866.
Having thus particularly described my said Invention, and the manner in
which the same is or may be used or carried into effect, I have to state that
what I claim as the Invention secured to me by the herein-before in part
recited Letters Patent is, the applying to or using in a self-propelling traction
engine of mechanisin for drawing or hauling a load towards the engine, or the

page_text: engine and load towards a fixed point, and the constructing of a traction
engine so as to be capable of either drawing, hauling, or carrying the load,
substantially as herein-before described.
In witness whereof, I, the said Alexander Chaplin, have hereunto
set my hand and seal, this Twelfth day of July, in the
Lord One thousand eight hundred and sixty.

year
