Improvements relating to Paving Roads and Tramways.
WILLIAM CANE SHADDOCK; Public Works Contractor 5, Hillsboro' Manna-

follows:-
My invention consists of the use of cast iron plates attached to cast iron guards
(one side only) or unattached as may be considered necessary: each plate to be
placed on its edge and slightly under finished surface of pavement, between each
row or course of paving stones, wood blocks or and in other substance where the use
of these plates would be effective in preventing ruts and so adding to the life of
such payements: these plates to break joint, and except where cast to a guard
against kerbs, and except where butting against lipes of iron or granite, to be of
such lengths as may be required to cover widths exceptionally exposed to heavy or
continuous traffic: each plate to be about three eighths of one inch in thickness and
having its edges cast to the required curvature of roadway or tramway.

COMPLETE SPECIFICATION.
Improvements relating to Paving Roads and Tramways.
I, WILLIAM CANE SHADDOCK; Public Works Contractor, 5 Hillsboro', Manna-
mead, Plymouth, Devon, 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 :-
My invention consists in the use of metal plates, preferably cast iron, attached
(one side only) to metal longitudinal guards hereinafter termed side guards adapted
to the outer face of the footway, kerbing, or unattached as may be considered
necessary; each plate to be placed on its edge embedded in the concrete or other
substructure or foundation of the roadway and slightly under the finished surface
of the roadway between each row or course of paving stones or "sets," wood blocks,
or in and between any other material or substance of which the road-proper is made
up and at such parts of the road or tramway where the use of said plates will
conduce by preventing ruts and other irregularities in the surface, add materially
to the longevity of roadways &c., to which the device according to my invention is
applied. Said protective plates to break joint when not used full width of pavement
and except where cast or attached to a side guard against the kerb or butting
against tram lines &c. to be of such a length as may be required to cover any
desired width of tramway or roadway exposed to heavy or continuous traffic.
"
The paving "sets or stones or the wood blocks at the portion of the roadway
not having the protective plates would be grouted in, in the usual way.
The thickness of the plates which I employ in accordance with my invention will
depend upon the requirements according to the nature of the traffic and so forth,
say from of an inch upwards as may be deemed necessary; the top of said plates
would be cast or formed to the required curvature of roadway or tramway.
In order that my invention may be the better understood, I have appended the
accompanying sheet of drawings.
Referring to which,
Figure 1 shows a cross section of roadway with the protective plates extending
the hath

page_text: Figure 2 is a plan view corresponding with Figure 1 but illustrative also of the
various methods of laying the plates, that is to say :-A, longitudinal side guard
herein before referred to B, arrangement adopted for heavy traffic, C, plates running
whole width of roadway or tramway, D arrangement where plates adjoin manholes
of sewers and the like, E similar in the case of gullies F arrangement of plates
where adjoining tramrails of roadway. G, the protective plates when laid at right
angles as shewn to the direction of the traffic and in certain cases where found to
be advantageous (still referring to Figure 2) they might be laid en-échelon as
shown.
Figure 3-section to an enlarged scale shewing continuous plates between kerb-
stone and tramrails dotted lines indicating the "break joint" arrangement.
Figure 4-section also to enlarged scale shewing 4 plates running out from kerb-
stone with end plate "dipped" to avoid any dangerous projection at this point.
Figure 5-another cross-section shewing 3 plates running out from tramrail with
end plate "dipped" to avoid any dangerous projection at this point.
The top of the protective plates where butting against iron (that is to say tram-
rails, as also manholes and other metal covers) to be arranged flush with the top
surface of the tramrails, manhole covers, gullies or the like, and the top of the
roadway paving to be slightly above as shewn at a Figures 3 and 5.
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 :
The novel means hereinbefore described and consisting in the use of metal
protective plates with a view to effect the longevity of roadways and the like,
substantially as herein set forth, and illustrated in the accompanying sheet of
drawings.
