PROVISIONAL SPECIFICATION.
An Improved Concrete and Metal Earth Block or Plate for Metallic
Fencing Standards and Posts.
I, LEWIS MOTLEY Engineer 30 Great George Street Leeds in the County of
York, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved construction of concrete and metal earth
block or ground plate for metallic fencing standards and posts, and consists of a
block of concrete provided with a suitable aperture and metal centre plate (which
centre plate is attached to the concrete block) into which the standard or post is
fixed. This block may be square circular, rectangular or of any other suitable
shape or form.
In order to further strengthen the said concrete & metal earth block I provide a
metallic frame, which may be either embedded in the body of the concrete block or
form an external band or casing for the same, or I may use both forms in
combination.

An Improved Concrete and Metal Earth Block or Plate for Metallic
Fencing Standards and Posts.
I, LEWIS MOTLEY, Engineer, 30 Great George Street, Leeds, in the 'County
of York, 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 :-
This invention relates to an improved construction of earth block or ground plate
for metallic fencing standards and posts, and consists of a block of concrete provided
with a suitable aperture and metal centre plate (which metal centre plate is attached
to the concrete block) into which the standard or post is fixed.
This block may be square, circular, rectangular, triangular, or any other suitable
shape or form, in plan view.
In order to further strengthen the said concrete and metal earth block I provide
a metallic frame which may either be imbedded in the body of the concrete block,
or form an external band or casing for the same, or I may use both forms in
combination.
With a view to fully explain my invention I have annexed a drawing on
which
Fig. 1 is a plan, and Fig. 2 a sectional elevation of a block made in accordance
with my combination.
Figs. 3, 4 and 5 are sectional elevations showing modifications.
Figs. 6, 7, 8 and 9 are referred to later.
The same letters refer to the same parts or their equivalents in all the figures.
Referring to Figs. 1 and 2:-
A is the concrete block; B is the metal centre plate; C is the metallic frame ;
and D is the standard, which is held in position by the wedge E. The block A is
built up of concrete in the usual way, and it may be moulded in any suitable
shape.

page_text: The metal centre plate B could of course be cupped so as to imbed itself on
every side into the block, but as this is expensive I simply bend the ends down as
shown, so that they may be securely held in the concrete. This centre plate is
modified into a tubular form in Fig. 3, and into a spiral, say of wire, or rod, in
Fig. 4; whilst in Fig. 5 it is shown as a flat plate sunk below the face of the block.
The ends of the wire in Fig. 4 require to be carefully intertwined or otherwise
locked in the concrete.
In Fig. 9 the centre piece B, in plan view, is shown built up in twisted wire or
rod, the ends of which are both intertwined and locked in the concrete.
The metallic frame C, which may be of any section, may be welded into a solid
ring, circular or otherwise, but to avoid expense 1 simply intertwine the ends of the
rod together (as shown in Fig. 6) which being afterward imbedded in the concrete
cannot give way. In Fig. 3 the frame takes the form of a thin plate, bent, say, into
a circle, with its ends, for the sake of economy, jointed by simple bending after the
manner shown in Fig. 7. In Fig. 4 the frame is modified into a layer of wire
netting there may be two or more such arranged in different planes. In Fig. 5
the frame is again of wire netting, here bent, say, into a circle, and jointed, by
simple bending, after the manner shown in Fig. 8. I prefer to entirely imbed the
frame, for the sake of its preservation, in the concrete, however near the outside of
the block it may be brought.
In making the blocks I prefer to make them upside down, as the centre piece B
can then rest on the bottom of the mould, with the "core" for the aperture holding
it in its place; the more liquid cement would then gravitate to the layer where the
greatest strength is afterwards required; viz. in the plane of the wedging action.
After filling up the mould to the required point, the frame C, or its equivalent, is
inserted, after which the concrete is filled up to the top of the mould. When, as
shown, a portion of the block is recessed, a corresponding projection in the cover of
the mould must of course be provided.
In fixing the standards they should be firmly driven into the ground at the
bottom of the recess cut for the earth block, and, when the block is finally in
position, the wedge E is inserted and driven tightly home. The nearer to the surface
of the firm ground the wedge and its plate is arranged and the deeper the point to
which the standard is driven the better, as the block is not a foundation stone but
only a side-thrust-block, as usual.
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. The improved concrete and metal earth block constructed, arranged, and put
to use, substantially in the manner described and shown.
2. In an earth block the combination of (1) a concrete block A, (2) a centre
piece B for receiving the pillar or post and taking the strain of the wedge, and
(3) a strengthening member C for holding the block together, substantially as
-described and shown, and for the purpose set forth.
3. In a concrete earth block the combination of any of the centre pieces B, with
any of the strengthening frames C, or their equivalents, substantially as described
and shown in Figures 1 to 9 inclusive, and for the purpose set forth.
4. In a concrete earth block for standards and posts, the mode of so arranging,
twisting, and finishing off, the various metal strengthening or other pieces, that
when imbedded in the concrete they are securely held, without expensive welding
and the like, substantially as described herein, and as shown.
