TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS 1
POOLLY COOPER, of No. 3, Frideswide Place, Kentish Town, in the
County of Middlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of February, in the
year of our Lord One thousand eight hundred and seventy-three, in 1
the thirty-sixth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Thomas Poolly Cooper,
Her special licence that I, the said Thomas Poolly Cooper, my
executors, administrators, and assigns, or such others as I, the said
Thomas Poolly Cooper, my executors, administrators, and assigns, 2
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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "AN IMPROVED MODE AND MEANS FOR CLOSING AND FASTENING 2
RAILWAY CARRIAGE DOORS," upon the condition (amongst others) that I, the
said Thomas Poolly Cooper, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
scals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and a
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 Thomas Poolly Cooper, 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:-
This Invention has for its object the closing and fastening simulta-
neously and unfastening without opening the doors of a railway passenger
train by means of a combination of rods and levers. For these purposes,
the hinges at present used to railway carriage doors are removed, and
the framework so altered that by fixing the pin A at the top and bottom
of each door, the door shall work on the hinge side in a groove. To one
pin of every door is attached the levers B which work into slots cut into
the longitudinal bars C. These bars are attached to the arms D which
are attached to the rack E into which the bevel wheel F works, being
actuated by the continuous rod G which extends the entire length of
the train, having a ball-and-socket joint between each carriage, this rod
being worked by machinery to be fixed in the guard's van or elsewhere,
as circumstances may require.
In order that when by means of the above described apparatus the
doors have been closed they may be locked. The pins H which are
attached to the rack are furnished with the two wedges I, one at each
end. These are connected by means of the rods J to the small keys K,
which are driven by force of the springs L into slots in the longitudinal
bar C, and the keys being held firmly in the groove in which they work
keep the longitudinal bar fixed, and the bar being thus fixed the levers
cannot be moved, or in other words the doors cannot be opened, they
being secured by the levers which run into the slots of the longitudinal
bar. To release the longitudinal bar therefore it is necessary to withdraw
the keys, which is done by means of the wedge I fixed to the pins H on
the rack, which wedge by partaking of the motion of the rack itself
draws the key out of the slot in the longitudinal bar, and thus releasing
it allows the aforesaid bar to be moved. The door pin lever being thus
released the door can be opened at pleasure.
In order that the doors on one side may remain permanently closed

page_text: prevents the key K from being pulled out of the slot in the longitudinal
bar C.
In witness whereof, I, the said Thomas Poolly Cooper, have here-
unto set my hand and seal, this Twenty-first day of August, in
the year of our Lord One thousand cight hundred and seventy- &
three.
