Improvements in and relating to Barriers and the like.
1 LOUIS ESTEVAN GREEN DE WOOLFSON of 26 St. John's Hill Shrewsbury in
the County of Shropshire Surgeon do hereby declare the nature of this invention
to be as follows:-
My invention relates to improved means of making a barrier of a collapsable
nature and has for its object to provide a simple and efficacious means of raising,
lowering and retaining the said barrier in position and the economy of space.
The general construction of the barrier is as follows:-
A series of vertical bars, solid or hollow of metal or other suitable material or
materials suitably constructed and fitted at their lower or butt end for connecting
and securing to drawing bar and to pivots, gudgeon pins or centre bolts made of cast
or Bessemer steel or case hardened iron. These vertical bars are further held
together and strengthened by one or more transverse bars of approved material and
make, suitably fitted and attached.
The centre bolts or gudgeon pins must be of suitable make, size and strength as
they serve to bind and firmly hold the barrier to any desired structure and also
have to resist the whole weight and movements of the said barrier.
The drawing bar of suitable material and construction can be fitted and secured
to a lever or levers, screw wheel, steam cylinder or other motive power, placed in
such a position as may be found convenient and necessary. Whitworth thread to
be used throughout the construction if necessary and also split pins for securing
nuts on bolts.
All parts may be made detachable.
When levers are used, they thould be fitted with securing chains, spring catch
or other securing means.
The vertical bars may be spiked if necessary.
The height, strength and length of the barrier to suit the requirements of the
structure or situation to which it is applied and fixed.
The barrier can be directly applied and suitably secured to platforms, level
crossings, stages of all kinds or any other suitable structure; or the barrier may be
made portable for transport purposes by fitting and securing it to a framework or
casing of approved construction, either of metal or other suitable material, preferably
cast or wrought iron, and have a lid fitted, secured and made removable if
necessary.
When the barrier is fitted and fixed to any structure, for example, a platform, the
whole of the barrier when down and not in use is completely hidden below the
surface in a suitably constructed bed in platform and is completely shut out of sight
by a lid running along its whole length and which is so suitably fitted and secured
by hinges to platform that it is raised and lowered by the barrier itself when
working.
Barriers used for field purposes may have, but do not require ends constructed
for attachment to drawing bar, as they can be worked by ropes or chains and a jib
connected to any desired motive power.
A suitably constructed and fitted collapsable jib of metal or other material with
rope and chain can be secured to the framework or casing of the barrier, and held
in the erect position when desired by means of a dog or retaining hook.
When used for field purposes one or more barriers can be connected by means of
coupling pieces or chains, suitably fitted and secured with D links and cotter pins
if necessary.

page_text: Suitable stops, or the edge of the framework or structure to which the barrier is
fitted and fixed will stop the moveable vertical bars of the barrier from going
beyond the erect position.
Any gap, in platforms or other structure to which the barrier is fixed and applied
for use, can be closed and made secure by a suitably constructed lid or stop gap
acting with or independently of the barrier as desired.
The principle of the barrier could be so applied as to act in the capacity of a
grating, hurdle, fence or protecting structure to cellars, windows or other
structures.
The whole or parts of the barrier can be made detachable.
In claiming protection for this barrier, I am claiming protection for the
application of a principle coupled with a mode of carrying the principle into
effect.

Improvements in and relating to Barriers and the like.
I Louis ESTEVAN GREEN DE WOOLFSON of 26 Saint John's Hill Shrewsbury
in the County of Shropshire, Surgeon do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention relates to improved means of making a barrier of a collapsable
nature and has for its object, to provide a simple and efficacious means of raising,
lowering and retaining the said collapsable barrier in position and the economy of
space.
The accompanying drawings describe my invention in which
Fig. 1 shows a longitudinal section of a platform with barrier raised.
Fig. 2. shews a longitudinal section of a platform with barrier lowered.
Fig 3. shews a longitudinal section of a wooden framework or casing C with
barrier for field purposes raised by rope and jib.
Fig. 4. shews the same lowered.
Fig. 5 vertical bar A shewing butt end a fitted for gudgeon pin g and for
drawing bar D at p².
The same letters refer to similar parts throughout the several figures.
The general construction of the barrier is as follows;-A series of vertical
bars A Figs. 1 to 5 solid or hollow of metal or other suitable material or materials
suitably constructed and fitted at their lower or butt end a Figs. 1 & 2 & 5 for
connecting and securing at p to drawing bar D. and to pivots, gudgeon pins or
centre bolts. Figs. 1 & 2 made of cast or Bessemer steel or case hardened iron.
These vertical bars A. are further held together and strengthened by one or more
transverse bars B. Figs. 1 to 4 of approved material and make, suitably fitted and
attached at and The centre bolts or gudgeon pins g must be of suitable
make size and strength, as they serve to bind and firmly hold the barrier to nuy
desired structure and also have to resist the whole weight and movements of the
said barrier.
The drawing bar D.. of suitable material and construction, can be fitted and
secured to a lever or lovers, screw-wheel, steam cylinder or other motive power,
placed in such a position as may be found convenient and necessary. Whitworth
thrend to be used throughout the construction if necessary and also split pins
for securing nuts on bolts.
All parts may be made detachable, if desired or necessary.
When levers are used, they should be fitted with securing chains, spring catch,
or other securing means.

page_text: The vertical bars A may be spiked at the upper part a Figs. 1 & 3 if necessary.
The height, strength and length of the barrier Figs. 1. 23 and 4 to suit the
requirements of the structure or situation to which it is applied and fixed.
The barrier can be directly applied and suitably secured to platforms, level
crossings, and stages of all kinds or to any suitable structure or structures, or the
barrier may be made portable for transport purposes by fitting and securing it to a
framework or casing Figs. 3 & 4 C of approved construction, either of metal or
other suitable material, preferably cast or wrought iron and have a lid L fitted,
secured and made removable necessary.
When the barrier is fitted and fixed to any structure, for example a platform P.
Figs. 1 & 2. the whole of the barrier when down and not in use is completely
hidden below the surface in a suitably constructed bed N. N. N. Figs. 1 and 2 in
platform and is completely shut out of sight by a lid L running along its whole
length and which is so suitably fitted and secured by hinges to platform P that it
is raised and lowered by the barrier itself when working.
Barriers used for field purposes Figs. 3 and 4 may have, but do not require,
ends a Figs. 1 & 5 constructed for attachment to drawing bar D as they can be
worked by ropes or chains R and a jib J Figs. 3 & 4 connected to any desired
motive power.
A suitably constructed and fitted collapsable jib J. Figs. 3 & 4 of metal or other
suitable material with rope and chain R can be secured to the framework or
casing C of the barrier and held in the erect position when desired by means of a
dog or retaining hook d Figs. 3 and 4.
When used for field purposes one or more barriers can be connected at e Figs. 3
and 4 by means of coupling pieces or chains, suitably fitted and secured with
D links and cotter pins if necessary.
Suitable stops S Figs. 1, 2 & 3 or the edge of platform or framework or
structure to which the barrier is fitted and fixed will stop the moveable vertical
bars A of the barrier from going beyond the erect position.
Any gap in the platforms or other structures to which the barrier is fixed and
applied for use, can be closed and made secure by a suitably constructed lid or
stop-gap acting with, or independently of the barrier as desired.
The principle of the barrier could be so applied as to act in the capacity
of a grating, hurdle, fence or protecting structure to cellars, windows or other
structures.
The whole or parts of the barrier can be made detachable if necessary.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
That the structure and working of my collapsable barrier is novel in its
application and use as a barrier and the like.
In claiming protection for this barrier, I am claiming protection for the
application of a principle coupled with a mode of carrying the principle into
effect.
