Year: 1873

page_text: LETTERS PATENT to James King, James Maxwell King, and Thomas
Dundas Maxwell King, all of 5, Moscow Terrace, Victoria Park,
in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
APPARATUS APPLICABLE TO RAILWAY PLATFORMS TO PREVENT PERSONS
ENTERING AND LEAVING TRAINS IN MOTION, AND FOR OTHER SUCH LIKE
PURPOSES."
Sealed the 1st April 1873, and dated the 8th February 1873.
PROVISIONAL SPECIFICATION left by the said James King, James
Maxwell King, and Thomas Dundas Maxwell King at the Office
of the Commissioners of Patents, with their Petition, on the 8th
February 1873.
WC, JAMES KING, JAMES MAXWELL KING, and THOMAS DUNDAS
MAXWELL KING, all of 5, Moscow Terrace, Victoria Park, in the
County of Middlesex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS APPLICABLE TO RAILWAY PLATFORMS TO

page_text: PREVENT PERSONS ENTERING AND LEAVING TRAINS IN MOTION, AND FOR OTHER
SUCH LIKE PURPOSES," to be as follows:-
This Invention has for its object improvements in apparatus appli-
cable to railway platforms to prevent persons entering and leaving trains
in motion, and for other such like purposes. We employ a rising and
falling fence running along the platform and capable of folding down
out of the way to allow of free passage or of being raised instantaneously
at the will of the operator when it is desired to obstruct the passage.
As applied to railway platforms it is preferred to place the fence in
such a position that the carriage doors cannot be opened when the
fence is raised. By preference we construct the fence of a series of
uprights jointed to the platform, and to horizontal bars, and capable
of folding down like a parallel ruler. A lever handle or wheel in a
convenient position is provided for raising and depressing the fence;
and the same lever or wheel works a signal for starting the train.
The fence can be made of any convenient length, and cither straight
or curved, and it may be in sections capable of being connected and
disconnected at pleasure.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said James King, James Maxwell King, and Thomas
Dundas Maxwell King, in the Great Seal Patent Office on the
8th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
KING, JAMES MAXWELL KING, and THOMAS DUNDAS MAXWELL KING,
all of 5, Moscow Terrace, Victoria Park, in the County of Middlesex,

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of February, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said James King, James Maxwell
King, and Thomas Dundas Maxwell King, Her special license that
we, the said James King, James Maxwell King, and Thomas Dundas

page_text: Maxwell King, our executors, administrators, and assigns, or such
others as we, the said James King, James Maxwell King, and Thomas
Dundas Maxwell King, 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 APPARATUS APPLICABLE
TO RAILWAY PLATFORMS TO PREVENT PERSONS ENTERING AND LEAVING TRAINS
IN MOTION, AND FOR OTHER SUCH LIKE PURPOSES," upon the condition
(amongst others) that we, the said James King, James Maxwell King,
and Thomas Dundas Maxwell King, 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 James King, on behalf of myself
and the said James Maxwell King, and Thomas Dundas Maxwell
King, 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 apparatus appli-
cable to railway platforms to prevent persons entering and leaving
trains in motion, and for other such like purposes. We employ a rising
and falling fence running along the platform and capable of folding
down out of the way to allow of free passage or of being raised
instantaneously at the will of the operator when it is desired to obstruct
the passage.
As applied to railway platforms it is preferred to place the fence in
such a position that the carriage doors cannot be opened when the fence
is raised. By preference we construct the fence of a series of uprights
jointed to the platform and to horizontal bars, and capable of folding
down like a parallel ruler. A lever handle or wheel in a convenient
position is provided for raising and depressing the fence, and the same

be made of any convenient length, and either streight or curved, and
it may be in sections capable of being connected and disconnected
at pleasure.

of
Figures 1 and 2 are elevations, and Figure 3 is a transverse section
a movable fence, applied to a railway platform in such manner
as to prevent persons entering and leaving trains in motion. In
Figure 1 the fence is in such a position as to allow free passage to
and from the carriages, and in Figures 2 and 3 it is raised so as to
prevent such passage.
a, a, are the rails; 6 is the railway platform on the side of which are
fixed in any convenient manner the studs c, c, which serve as axes for
the bars d, d, which are also jointed to the horizontal bars e, e. One of
the bars & in place of being mounted upon a stud d is fixed at the end
of the shaft f; this shaft is mounted in suitable bearings and to it the
lever handle g is also attached, so that by means of the handle the
shaft can be turned partly round, and this movement serves to raise or
depress the fence which the bars d and e form. The lever handle g is also
connected with the station signal h, so that the same act which directs
the starting of the train places the fence in such a position that the
carriage doors of the train cannot be opened. A balance weight, not
shewn in the Drawings, is provided so that no more power is required
to raise the fence than to lower it. One man will be able casily to
work the apparatus.
The bars e, e, may be made, divided into separate lengths so that
parts may be temporarily removed, as for example, where a cross road
passes through the platform for the conveyance of carriages from one

page_text: prevent persons entering and leaving trains in motion, and for other
such like purposes, substantially as described.
In witness whereof, I, the said James King, have hereunto set
my hand and seal, this Eighth day of August, in the year of
our Lord One thousand eight hundred and seventy-three.
