AN IMPROVED COPING TILE
Year: 1884

page_text: I WILLIAM TUFFEE of 3 Union Street, Gravesend in the county of Kent,
Builder do hereby declare the nature of my said invention for AN IMPROVED
COPING TILE to be as follows:-
The object of my invention is to provide a coping tile that shall prevent the
percolation of rain or moisture or weather into the wall on which it is placed
whether the upper surface of the said wall be sloping or horizontal.
To carry out this object I make the coping tile of any material and size and it is
placed across the top of the wall and projects beyond the same on each side
thereof and is then returned or bent over downwards. These tiles are placed in
juxtaposition on the top of the wall and the meeting edges thereof are not
rectangular and rectilinear but are rounded off horizontally or made of a semicircular
shape or thereabouts and to make the transverse joints between these said tiles
tight I form the said tiles in the following manners.
When the upper surface of the wall is sloping I raise the surface of the tile at its
lower edge and prolong the same beyond the said lower edge so that this raised
prolongation extends a suitable distance over the surface of the next adjacent tile
below. This raised prolonged part of the surface of the tile preferably does not
extend the whole width of the tile but is only formed on the central portion
thereof over the wall but it is a little broader than the said wall. The rounded
meeting edges of these tiles are also so arranged as to curve downwards on each
side and thus the water is thrown entirely off before it drips. The lowest of these
sloping tiles butts in the same manner on the horizontal tile if any at the base of
the slope and is filled up underneath with any convenient and suitable material.
When the upper surface of the wall is horizontal I prefer to inake each tile with
a locking drip under the raised prolonged portion of one edge which engages a
suitable recess formed therefor in the surface of the next adjacent tile and the
returned or bent over edges of the tiles overlap each other to prevent the passage
of any moisture through the meeting edges thereof.

page_text: 1 WILLIAM TUFFEE of 3 Union Street Gravesend in the county of Kent,
Builder do hereby declare the nature of my said invention for AN IMPROVED
COPING TILE and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of my invention is to construct and provide a coping tile by the use
of which on the upper edges of walls the percolation of rain or moisture or weather
into the walls on which a series of these tiles have been placed shall be entirely
and completely prevented whether the upper edges of the said walls be sloping or
horizontal.
To carry out this object I make the coping tile of any suitable material and size
having regard to the wall on which it is to be placed and it is made broader than
the said wall so that it projects beyond the same on each side thereof and is thero
. returned or bent over vertically downwards or thereabouts and to cover the
transverse joints between the said tiles when placed in juxtaposition on the upper
edge of the wall a certain part of the upper surface of each tile is raised and
prolonged so that it projects a certain desired distance over the upper surface.of
one of the next adjacent tiles.
In order to fully and clearly explain my said invention and in what manner the
same is to be performed I refer to the accompanying drawing.
Figure 1 is a plan of the upper surface of a coping tile made according to this
my invention. Figure 2 is a cross section of the same taken at a. b. in Figure 1.
Figure 3 is a cross section of the same taken at c. d in Figure 1.
The tile A is made of any suitable material and size as aforesaid and the ends or
meeting edges thereof are not rectangular or rectilinear but are rounded off
horizontally or made of a somewhat semicircular shape as shewn. A certain
desired part A¹ of the upper surface of the tile is raised and prolonged beyond one
of the ends of the tile A as shewn at B. The lateral sides of the tile A are
returned or bent downwards as shown at C. The raised part A' of the upper
surface of the tile preferably does not extend the whole width of the tile A but is
only formed on the central portion thereof being made a little broader than tho
wall D that it is to cover and this raised part A' may be made rectilinear and
rectangular in cross section as shewn in these Figures in which case I prefer to
form a small wedge shaped piece E on the edge of the tile and against the raised
part A to assist in guiding tho water or moisture or weather away from the
extremities of the transverse joint between the two adjacent tiles or tho said raised
part A' may be made of a curved form as shewn in Figure 4 which is a cross
section of a tile constructed and formed in this manner taken at or about the
middle of its length. In either case the prolonged part B would be formed of the
same section as the raised part A¹.
Figure 5 is an elevation of a wall with a sloping upper edge covered with these
my improved coping tiles herein before described which tiles are partly in section―
Figure 6 is a plan of the same.
The tiles A are placed in juxtaposition on the upper edge of this wall D in such
a manner that the prolonged part B of the upper surface of the one tile projects,
over the upper surface of the tile next immediately below and thus covers the
transverse joint between the two adjacent- tiles whilst the rounded or curved ends
or.meeting edges of all the tiles are so arranged as to curve downwards on each
side as shewn in dotted lines in Figure 6 and thus the water is thrown entirely off
before it drips and the returned or bent downwards lateral sides C of the tiles also

page_text: assist in preserving the top of the wall. The lowest of these sloping tiles A abuts
in the same manner on the horizontal tile F if any at the base of the slope which
tile F is also preferably formed as shewn to fill up the space underneath the
prolonged part B of the said lowest tile A or this space may be filled up. ia any
convenient manner as may be desired. The outer edges of the tile Fare also
returned or bent downwards as shewn at G and thus and in this manner as
aforesaid the whole of the upper edge of this wall is protected against any
percolation of rain or moisture or weather as is dosired.
In Figure 7 I shew a longitudinal section of these tiles as fitted to be placed on
the horizontal upper edge of a wall in which case the tiles A are made in the same
manner as herein before described but to provent any rain or moisture or weather
passing in under the prolonged part B I preferably make a locking drip ■ thereon
which engages in a suitable recess formed therefor in the surface of the next
adjacent tile and the returned or bent downwards lateral sides of these tiles may
also be formed to overlap each other and thus the meeting and covering edges and
sides of these tiles are also made weather tight.
It is obvious that I can make these my improved coping tiles of any dimensions
or proportions that I may deem expedient in each particular case and that I do
not in any wise limit myself to the precise forms thereof as shewn in the drawing
though I consider that for ordinary walls and ordinary purposes the dimensions
and proportions and forms as so shewn are extremely suitable.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be perforined I declare that what
I claim is
1. The coping tile a certain part of the upper surface whereof is raised and
prolonged beyond the tile at one end and the lateral sides wheroof are returned or
bent downwards substantially as and for the purpose hereinbefore described and
declared.
2. The method or manner of using and arranging the coping tiles herein before
described and claimed the said method consisting of and being the placing the said
tiles in juxtaposition in such a manner that the prolonged projecting part of the
one tile overlaps part of the next adjacent tile substantially as hereinbefore
describod and set forth.
