COMPLETE SPECIFICATION.
'Improvements in the Manufacture of Roofing Tiles."
I, GEORGE EDWARD EVANS, of Church Street, Bridgetown, Cannock, in the
County of Stafford. Engineer do hereby declare the nature of my said 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 has for its object improvements in the manufacture of roofing
tiles by which I am enabled to form them with the required sweep or curve
during the operation of pressing and when in a plastic state which curve has
hitherto been formed after the pressing operation and has not always been regular
or uniform but by my invention every tile is bent uniform and regular thus
ensuring a perfect fit when in position on the roof.
In order that my invention may be clearly understood and easily carried into
practice I have appended hereunto a double sized sheet of drawings upon which I
have illustrated examples of my improvements.
Figure 1 shews an elevation of the top and bottom dies for forming. tiles
according to my invention.
Figure 2 is an end elevation of Figure 1 shewing the recesses a¹ formed in
the top die for forming the nibs on the tiles.
Figure 3 is a cross section taken on the line -y in Figure 1.
Figure 4 is a perspective view shewing the underside of a finished tile made
according to my invention.
In carrying my invention into practice I form the top die A, convex
longitudinally on its inner or lower surface and the bottom die B is formed
concave longitudinally or its upper surface to correspond so that when the two dies
are brought together they fit accurately as shown at Figure 1. It will thus be
seen that when these dies are fitted into the press or moulding apparatus and the
clay or plastic material which has been previously prepared placed between, that
the clay when pressed will receive the curved form of the dies which is necessary
when fixing the tiles on to a roof so as to allow each tile to overlap. The top die
is provided with the recesses, for forming the nibs t₁ on the end of the tile T as
shown at Figure 4 which catch on to the laths of the roof for holding or keeping
the tiles in position. Instead of forming the surface of the top die convex
longitudinally may form it concave and the bottom die convex longitudinally to
correspond. In this case the recesses for forming the nibs on the tile would be
formed in the bottom die.
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:-
CLAIMS
C

page_text: pieces of clay between dies such as A and B which press the clay to the required
thickness and at the same time form the nibs t, the dies being so formed as shewn
so as to leave the tiles hollowed such as seen at Figure 4 at one process substantially
as herein set forth and shown.
Third: In the manufacture of roofing tiles forming the dies between which the
tiles are pressed so as to impart to the tiles the necessary curve sweep during the
operation of pressing in the manner and for the purpose substantially as
herein before described and as shown upon the accompanying sheet of drawings.
Dated this 14th day of October 1897.
