Year: 1869

page_text: LETTERS PATENT to Jonathan Robert Baillie, of No. 1, Rochefort
Villas, Hoe Street, Walthamstow, Naval Architect, for the
Invention of "IMPROVEMENTS IN WAGGONS FOR CARRYING COAL, COKE,
Scaled the 21st September 1809, and dated the 25th March 1869.
PROVISIONAL SPECIFICATION left by the said Jonathan Robert
Baillie at the Office of the Commissioners of Patents, with his
Petition, on the 25th March 1869.
I, JONATHAN ROBERT BAILLIE, of No. 1, Rochefort Villas, Hoc
Street, Walthamstow, Naval Architect, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN WAGGONS FOR CARRYING COAL, COKE,
BALLAST, AND OTHER LIKE GOODS AND MATERIALS," to be as follows: -
My Invention has for its object an increased facility in regulating and
controlling the discharge of the contents of coal and other waggons,
and consists in the adaptation and application to such waggons of doors
or flaps working on a shaft or pivot, and being moved thereon as
required by means of a worm toothed sector and worm turned by a
winch or by other means as herein-after stated. The said door or flap
has its pivot nearer to one side than the other of the opening in the
bottom of the waggon, thereby giving more weight on one side of the
pivot than on the other in order that the flap or door may have a

mechanical means employed for the purpose. Instead of a worm and
toothed sector the falling of the flap or door may be regulated and
controlled as required by means of a lever or levers, chain and pulleys
straight bar, sliding bar, wedge, or other suitable mechanical
appliance. Two or more waggons may be arranged with their several
discharging flaps or doors mounted on a common shaft or pivot, the
turning of which by suitable mechanical means would regulate or control
the several flaps or doors simultaneously as required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jonathan Robert Baillie in the Great Seal Patent
Office on the 24th September 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JONATHAN
ROBERT BAILLIE, of No. 1, Rochefort Villas, Hoe Street, Walthamstow,
Naval Architect, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of March, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Jonathan Robert Baillie, Her
special license that I, the said Jonathan Robert Baillie, my executors,
administrators, and assigns, or such others as I, the said Jonathan Robert
Baillie, my 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 WAGGONS POR CARRYING COAL, COKE, BALLAST, AND OTHER
LIKE GOODS AND MATERIALS," upon the condition (amongst others) that
I, the said Jonathan Robert Baillie, my executors or administrators,
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 Jonathan Robert Baillie, 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 following statement, reference being had to the Drawings
hereunto annexed, and to the letters and figures marked thereon (that
is to say):
==
My Invention of "Improvements in Waggons for Carrying Coal,
Coke, Ballast, and other like Goods and Materials" has for its object
an increased facility in regulating and controlling the discharge of the
contents of coal and other waggons, and consists in the adaptation and
application to such waggons of doors or flaps working on a shaft or
pivot, and being moved thereon as required by means of a worin
toothed quadrant and worm turned by a winch or by other means as
herein-after stated. The said door or flap has its pivot nearer to one
side than the other of the opening in the bottom or side of the waggon
thereby giving more weight on one side of the pivot than on the other
in order that the flap or door may have a tendency to fall open to its
full extent when not controlled by the mechanical means employed for
the purpose. Instead of a worm and toothed quadrant the falling
of the flap or door may be regulated and controlled as required by
means of a lever or levers, chain, and pulleys, a straight bar, sliding
bar, wedge, or other suitable mechanical appliance. Two or more
waggons may be arranged with their several discharging flaps or doors
mounted on a common shaft or pivot, the turning of which by suitable
mechanical means would regulate or control the several flaps or
doors simultaneously as required.
Having thus stated the nature of the said Invention, I will proceed
to describe more particularly in what manner the same is to be
performed by reference to the accompanying Drawings, in which is
represented one of the means for regulating and controlling or gradually
opening the said doors above referred to.
In Sheet I. Fig. 1 is a half elevation and longitudinal section; Fig. 2
is a half end view and transverse section, and Fig. 3 is a half plan and
horizontal section of a waggon fitted with balance doors moving on
spindles.
In Sheet II. Figures 1, 2, and 3 are corresponding Figures representing
a waggon with doors supported and moving on hinges.

page_text: In these several Figures the same letters of reference indicate
corresponding parts..
A, A, are the doors or flaps which in sheet I. are represented as
balanced and supported on spindles B, B, which spindles are fitted in
looso bearings G, G. The doors or flaps A, A, in Sheet II. are supported
on hinges B, B, fixed in the frame of the waggon; C, C, are the toothed
quadrants fixed on to the door spindles B, B, as shewn in Sheet I., or
on to the face of the doors, as shewn in Sheet II. D, D, are right and
left handed screws fixed on to the spindle E for working the toothed
quadrants C, C, which spindle is supported in bearings H, and is acted
upon as required by mears of the handle F. It will thus be seen that
the doors or flaps A, A, (either balanced or hinged) in the bottom or
sidos of waggons may be gradually opened as required by means of the
handle F acting on the spindle E so as to discharge the coal or material
contained in such waggons in larger or smaller bulk at the will of the
operator, thereby preventing much breakage, and admitting of the
closing of the doors or flaps as required.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I hereby declare that what I claim
as of my Invention is, the adaptation and application to waggons for
carrying coal and other materials of balanced or hinged doors or flaps
worked by toothed quadrants as represented and described or by other
suitable mechanism for regulating and controlling the opening of such
doors and flaps in the manner and for the purpose described.
In witness whereof, I, the said Jonathan Robert Baillie, have
hereunto set my hand and seal, the Twenty-second day of
September, in the year of our Lord One thousand eight hundred
and sixty-nine.
Witness,
