1 ROBERT RAMSAY MAIN of Clydesdale Iron Works, Possilpark, Glasgow, in the
County of Lanark, Engineer, do hereby declare the nature of this Invention to
be as follows:--
In erecting bar, wire and similar fonces it is customary to apply to the lower ends
of the standards a base or earth plate having for its object to give increased rigidity to
the standard and with the ordinary construction of this combination it is found that
when vertical pressure downwards is put upon the fence the standards and the bases
or earth plates are liable to sink into the ground and so destroy or disturb the true
regularity or continuity of the structure.
This Invention has for its object by an improved construction of base or earth plate
to obviate or lessen the sinking of the standards and plates under vertical pressure or
weight and the improvement consists in providing the plate with wings, shoulders or
projecting flanges at its upper end. The plate is at its middle part creased out to the
shape or contour of the standard or of such part of it as the plate has to embrace-the
standard being first driven into the ground and the plate then slipped down over it
and sunk into the ground to the required depth. Under one mode of construction the
shoulders or projecting flanges are produced by cutting the plate downwards throughout
a part of its depth-the cuts being parallel to the length of the crease or to the length
of the standard. From the cut to the edges of the plate the metal is bent over
horizontally or to any desired angle the flanges or shoulders so produced lying both in
one direction or in opposite directions. Under another mode the cutting of the plate
may be dispensed with in which case the wings, shoulders or flanges are formed by
simply bending the plate at its top upper corners-the bends being both in the same
or in opposite directions. With this improved formation when vertical pressure is put
upon the plate the wings, shoulders or flanges catching or pressing on the ground
prevent undue sinking of the plates and standards.

Improvements in "Earth" or Buse-plates for Fencing Standards and
the like.
I, ROBERT RAMSAY MAIN of Clydesdale Iron Works, Possilpark, Glasgow, in the
County of Lanark, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
In erecting bar wire and similar fences it is customary to apply to the lower ends of
the standards a base or earth plate having for its object to give increased rigidity to
the standard and with the ordinary construction of this combination it is found that
when vertical pressure downwards is put upon the fence the standards and the bases or
earth plates are liable to sink into the ground and so destroy or disturb the true
regularity or continuity of the structure."
The
This Invention has for its object, by an improved construction of base or earth
plate, to obviate or lessen the sinking of the standards and plates under vertical
pressure or weight and as seen by the several figures on the appended drawings the
improvement consists in providing the plate with wings, shoulders or projecting
flanges at its upper end. Under one arrangement, illustrated in elovation at figure
and in plan at figure 2 of the drawings, the earth plate a, is, at its middle part, creased
out to the shape of such part of the standard b as the plate has to embrace.
standard is driven into the ground and the plate is then slipped down over it or it
may be slipped on to the standard from the top or bottom before driving, the plate in
any case being sunk into the ground to the required depth, and thereafter secured in
position by a wedge c driven vertically. As illustrated by figures 1 and 2 the
shoulders or projecting flanges d are produced by cutting the plate downwards
throughout a part of its depth, the cuts being parallel or inclined to the length of the
crease e or of the standard b. From the cut to the edges of the plate the metal is
bent over horizontally or to any desired curve or angle the flanges or shoulders so
produced lying both in one direction or in opposite directions as indicated by the
dotted lines d' figure 2.
Under another mode shown in elevation at figure 3 and in plan at figure 4 the
cutting of the plate may be dispensed with and the wings, shoulders or flanges & formed
by simply bonding or curving the plate at its upper corners, the bends or curves being
both in the same or in opposite directions. With this improved formation, when
vertical pressure is put upon the plate, the wings, shoulders or flanges, catching or
pressing on the ground, prevent undue sinking of the plates and standards.
Instead of employing only one base plate for each standard two such plates may
be used as indicated under one modification in elevation at figure 5 and in plan
at figure 6 or a greater number may be employed and in lieu of securing
the plates figures 3, 4, 5 and 6 to the standard by creasing them at the middle and
driving a wedge between the crease and the flange of the standard the crease may bo
dispensed with and the plates may be secured by rivetting, bolting or otherwise
fastening them to the standards.

page_text: 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:
1. A base plate for fencing standards creased vertically at or near the middle to fit
the flange of the standard and cut vertically or at an angle between the said crease and
the ends of the plate the top edges between the cuts and the ends of the plate being
bent or curved over in the same or in opposite directions substantially as described
with reference to figures 1 and 2 of the annexed drawings.
2. A base plate for fencing standards creased vertically at or near the middle to fit
the standard and having its top edges bent or curved over in the same or in opposite
directions substantially as described with reference to figures 3 and 4 of the annexed
drawings.
3. A base plate for fencing standards having its top edges bent or curved over in
the same or in opposite directions as indicated at figures 3 and 4 and secured to the
standard by bolts, rivets or like fastenings.
