IMPROVEMENTS IN CONTINUOUS BAR AND HURDLE FENCING to be as follows:-
Year: 1884

page_text: I, WILLIAM PHILPOT CURRAN BAIN of Lower Gilmore Place Edinburgh in the
County of Midlothian, Fenco Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN CONTINUOUS BAR AND HURDLE FENCING
to be as follows:-
"
This Invention relates to improvements in continuous metal fences whether of
the bar or hurdle description, that is to say, whether built up in situ, or previously
constructed in complete sections which sections are merely joined together in
erecting the fence,
The Invention relates both to posts or standards and to bars for such fences and
as regards the bars it consists in forming them of plates preferably of steel and bent
into a A, cylindrical, or such other shape in transverse section as will enable an
outward springing tendency to be given to them. These bars are or may be
constructed in the usual lengths and they are used in conjunction with hollow or
tubular posts or standards of any desired shape in horizontal section. These
standards may be made in one piece or they may be formed of two pieces joined or
connected together by flanges and bolts, rivets, or equivalent means. The inter-
mediate standards between the ends of each bar may preferably be in one piece
and the standards at the ends of each bar of two pieces with inwardly turned
flanches against which the bars abut and so prevent lateral play under pressure, or
the bars inay be notched and the ends of the flanges entered into the notches or a
hole may be formed in each bar through which a vertical rod or key passes the said
rod or key (in the event of such pressure being exerted on the bars as would tend
to draw them out) locking them in position by contact with the interior of the
tubular standard. Or the ends of the bars may be joined by two narrow rect-
angular tubes, a long rod, or wire being passed through the ends of the bars inside
each tube, to prevent the bars being drawn out.
The holes in the standards through which the hollow bars pass are of a contour
corresponding to that of a transverse section of the bars. In passing the hollow
bars through these holes they are compressed and after being so passed they are
allowed to spring out again or expand whereby they are made to impinge firmly
against the sides of the holes such pressure holding them firmly, in position.
In lieu of the standards being tubular they may be dished or concave, in some
cases they may be of the usual flat or other formation.

page_text: I, WILLIAM PHILPOT CURRAN BAIN of 'Lower Gilmore Place Edinburgh in the
County of Midlothian, Fence Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN CONTINUOUS BAR AND HURDLE FENCING"
, and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
This invention relates to improvements in continuous metal fences whether of
the bar or hurdle description, that is to say, whether built up in situ or previously
constructed in complete sections the sections being merely joined together in erecting
the fence.
The invention relates both to posts or standards and to bars for such fencing and
with reference to the bars the improvement consists in forming them of plates
(preferably steel plates) bent into a triangular form as seen in cross section at a,
figure 1, or into a circular form as seen at b, figure 2, or into any equivalent shape
which will enable an outwardly springing tendency to be given to them the said
tendency being produced by leaving a space c, between the meeting edges of the
bent plate. The bars so constructed are or may be made in the usual lengths and
they are employed in conjunction with hollow or tubular posts or standards of
round, oval, or any other desired form in horizontal section and having holes
corresponding in shape to the transverse section of the bars cut in them. The bars
when being inserted through these holes are compressed and after being passed into
place are allowed to spring out again and grip the sides of the holes and are thereby
held in position.
The standards intermediate between the ends of the bars are each made of one
piece of iron or steel plate bent or curved to the desired oval, round, or other form
or they may be made in half sections which when placed and secured together will
constitute the said form, and the standard at the ends of each bar may also be in
one, but is preferably made in two pieces the plates being bent with inwardly
turned flanges as at d, figure 3, against which the ends of the bars may abut and so
prevent lateral play under pressure; or with the like object and to prevent them
being drawn out of place a hole may be made near the end of each bar and a rod or
wire passed vertically through it as indicated at 1, figures 1, 2, and 3, the said rod or
wire, which passes through all the bars in the depth of the fence, by contact with the
inner side of the tubular post locking the bars in position, or the bars may be notched
and the flanges of the standard entered into the flotches as indicated at e, figures 4,
and 5, the spring on the bar enabling it whilst being inserted to be sufficiently
compressed to pass the part f, g, of the bar through the space i, between the ends of
the flanges of the standard.
Figure 6, shows in plan a.modified form of the hollow end standard, a rectangular
iron or steel tube k, being substituted for each half of the end standard before
described.
With this arrangement and also with that shown at figures 1, 2, 3, 4, and 5, the
half standards at the meeting ends of two bars in the fence, in erecting the fence
are or may be bolted or rivetted together as shown at j, figure 7.

page_text: Figure 8, is a perspective view of two hurdles in the length of a fence constructed
in accordance with my invention and figure 9, is a plan of one such hurdle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
First A continuous, or hurdle, bar fence composed of tubular or hollow bars
and tubular or hollow standards or posts the bars being retained in position by
flanges at the interiors of the posts, by vertical rods, or by notching the bars sub-
stantially as described with reference to the drawings annexed.
Second-In continuous or hurdle fences hollow bars having each an opening
throughout its length, rendering it capable of being compressed whilst being
inserted, and thereafter sprung out to grip the standard substantially as described
with reference to the drawings annexed.
Third In continuous, or hurdle, bar fencing hollow or tubular standards or posts
constructed substantially as described with reference to the drawings annexed.
Dated this Second day of May 1885.
