PROVISIONAL SPECIFICATION left by the said David Rowell at the Office
of the Commissioners of Patents on the 14th December 1881.
"IMPROVEMENTS
DAVID ROWELL of Poets Corner in the City of Westminster.
IN FENCES GATES AND OTHER LIKE ENCLOSURES OR CLOSURES WHICH IMPROVE-
MENTS ARE ALSO APPLICABLE TO TELEGRAPH POLES AND SIMILAR SUPPORTS."
My Invention relates to improvements in fences gates and other like enclosures
or closures whereby great strength and rigidity are economically obtained.
In carrying out my Invention as applied to the construction of a fence for
example I make the longitudinal or perpendicular rails of the fence or the stays
for the pillars and uprights by taking a piece of hoop sheet or other metal and
bending it at one or both edges into a tubular or semi-tubular oval or flat shape
the remaining portion of the rail being either flat or formed with a central
corrugation, or (when both edges are bent) being formed either vertical or inclined
with the tubes or semi-tubes or other bends either both on the same side or on
opposite sides respectively of the flat portion. Two rails of one of the sections
hereinbefore described may be attached together by rivetting or other suitable
means so as to form a compound rail possessing great strength economically
distributed to equally meet the varying strains brought to bear upon the different
parts of the rail.
With the rails thus constructed (and which may be employed in
any required number) I combine posts or uprights of the same construction or any
suitable section either of metal or of wood preferably the former :-For example
the posts may be constructed of a similar section to the rails, and placed either at
one or both sides of the latter. I may also combine with the rails wire, wire netting
or vertical rods, according to the purpose for which the fence is intended to be
applied.
In the construction of gates and fences I may combine with the rails corrugated
metal or plain sheets either galvanised or otherwise.
The Invention is also applicable to hurdles telegraph poles and other like
purposes.

DAVID ROWELL of Poets Corner in the City of Westminster. "IMPROVEMENTS
IN FENCES GATES AND OTHER LIKE ENCLOSURES OR CLOSURES WHICH IMPROVE
MENTS ARE ALSO APPLICABLE TO TELEGRAPH POLES AND SIMILAR SUPPORTS."
My said Invention relates to improvements in fences gates and other like
enclosures or closures, which improvements are also applicable to telegraph poles
and similar supports by which improvements great strength and rigidity are
economically obtained.
In carrying out my said Invention as applied for example to the construction of
fences I make the longitudinal rails of the fence or the stays for the pillars or
uprights by taking a piece of hoop bar, sheet, or other metal and bending it at one
or both ends or edges into a tubular or semitubular shape. The remaining or
intermediate portion of-the-rail-may-be-either-flat-or-formed_with_a_central corru-
gation or corrugations and (when both ends or edges are bent) the said intermediate
portion may be formed either vertical or inclined with the tubes or semi tubes or
other bends either both on the same side or on opposite sides respectively of the
said flat portion Two rails of the sections herein before described may be attached
together by rivetting or other suitable means so as to form a compound rail
possessing great strength economically distributed to equally meet the varying
strains brought to bear upon the different parts of the rail With the rails thus
constructed (which may be employed in any required number) I combine posts or
uprights of the same construction or any other suitable section either of metal or
of wood but preferably of metal. For example the posts may be constructed of a
similar section to the rails and be placed either at one or both sides of the latter.
I may also combine with the rails wire wire netting or vertical rods according to
the purpose for which the fence is intended to be applied.
In the construction of gates and fences I may combine with the rails corrugated
metal or plain sheets either galvanized or otherwise protected or not.
The Invention is also similarly applicable to the construction of hurdles telegraph
poles and other like structures.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several Figures on the annexed Sheet of Drawings the same letters of
reference indicating corresponding parts in all the Figures.
The said Drawings represent various sections of rails "stays pillars or supports
for fencings telegraph posts or similar purposes constructed or formed according to
my said Invention in order to give great strength with but small weight by an
economical and effective distribution of metal so that a very substantial structure
can be made therewith.
Figures 1 and 2 illustrate various sections of curved or tubular ends edges or
terminations forming various portions of circles and other conformations.
Figure 3 shews modifications in which the rails stays or supports are formed
with central corrugations. Figures 4 and 5 shew respectively two pieces of
similar section rivetted or suitably united together and connected by a distance
piece.
Figures 6 and 7 represent a perspective elevation and plan of a bar band or
sheet of metal of the above described section for use as a pillar or perpendicular
support or as the top hand rail of a fencing or for similar purpose or as a component
part of such structures.

page_text: In all the Figures A A represents pieces of hoop bar sheet or other convenient
form of metal which are bent at their ends edges or sides into curved or tubular
shaped terminations a so as to form the rails stays pillars or supports.
The degree of such curvatures may be varied according to requirements for
example as represented in Figure 2 of the Drawings.
The middle part between the edges may be plain or straight as shewn in
Figure 1 or be formed with one or more central corrugations as at b as in Figure 3
or the said middle part may be formed as a compound structure consisting of two
separate pieces or rails of the above described sections rivetted or united together
as shewn in Figure 4 of the Drawings. A distance strut or piece P may be
employed as a means of connection for such compound rail or support as repre-
sented at Figure 5. It will be seen by reference to the various examples shewn
that the curved or tubular edge or edges of the rails or supports may be both bent
or turned in the same or opposite directions while the flat web or body may occupy
a straight or inclined position relatively thereto In this manner rails stays or
supports and the like are obtained very light owing to the economical but effective
distribution of metal whereby they are better able to resist the varied strains and
pressure brought upon such structures.
In Figure 6 of the Drawings a rail or bar formed according to my Invention is
shewn as forming a perpendicular stake pillar or support or a component number
of such structures suitable for carrying rails or wires of fencing or for supporting
the latter or for telegraph posts for which latter purpose a number of such bent
plates would be combined in square or other form and rivetted or otherwise con-
nected together so as to build up the required structure.
Figure 7 shews a form applicable for the top hand rail of gates fencings or
similar structures I may employ the rails or supports formed according to my
Invention either separately or in combinations of various numbers and sections of
the same or different kinds and also if desired I use in connection therewith posts
or uprights of wood or wire, wire netting, metallic sheets or rods or the like
according to the class of structure to which my Invention is applied.
Having now described and particularly ascertained the nature of my said Inven-
tion and the manner in which the same is or may be used or carried into effect I
would observe in conclusion that what I consider to be novel and original and
therefore claim as the Invention secured to me by the herein before in part recited
Letters Patent is.
The improvements in fences gates telegraph poles and other like enclosures or
closures or supports or analogous structures substantially as and for giving the
advantages herein before described with reference to the accompanying Drawings.
In witness whereof I the said David Rowell have to this my Specification
set my hand and seal this Thirteenth day of June One thousand eight
hundred and eighty two.
DAVID ROWELL. (L.S.)
