A NEW ROOFING TILE
Year: 1884

page_text: We JOHN GEORGE STADLER, Tilemaker at Lollikofen in Switzerland, EMIL
SCHMID, Architect at Zürich in Switzerland, do hereby declare the nature of
said invention for " A NEW ROOFING TILE" to be as follows:-
This invention relates to an improved construction of tiles and has for objects,
(1) To make the tile body of uniform thickness, and afford an efficient covering
without difficulty of production.
(2) To obviate having exposed surfaces rough cut by wire, and thus to ensure
greater resistance to percolation of water.
(3) To provide free and efficient means of escape for water.
In the accompanying drawings Fig 1 is a longitudinal section of two adjoining
tiles. Fig 2 a view shewing three tiles in cross section, and two in edge elevation
Fig 3, an isometrical view of five tiles shewing the way in which they overlap.
These tiles are made of bands of clay-each tile having a flat main portion b of
uniform thickness, having at the upper surface near one end a raised part or
bulge c with a recess c¹ in the underface thereof. Each longer side of the tile is
formed with a groove and tongue, fillet or projection as usual, and as indicated at d
and h. The lower face of the tile is moreover provided with the two projections e,
or there may be only one.
Such tiles may be manufactured either in hand presses, or as a continuous band
in machine presses. In the latter case a wire is used to cut away the unnecessary
part of the projections e, while the recessed portion c c' of the tile is pressed
between an upper and a lower mould into the desired shape.
The method of overlapping is shewn in Figs I and III.
The projections c are hung upon the root lathsf (see Fig I) in such a manner,
that the recess c¹ of one tile covers the ridge c formed by the groove and tongue or
fillet joint d of the two tiles below. Any water running off the surface 6 of the
upper tile is diverted by the bulge c on to the surfaces bb below, whilst, moreover,
any water entering the joint h d on an upper tile runs away on the surface b of the
next lower tile.

page_text: We, JOHN GEORGE STADLER, Tilemaker at Lollikofen in Switzerland, and EMIL
SCHMID, Architect, at Zurich, in Switzerland, do hereby declare the nature of said
invention for "A NEW ROOFING TILE" 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 roofing tiles and has for
objects:―
(1) To produce as a continuous clay band by means of a press a tile body of
uniform thickness, and afford an efficient covering without difficulty of production.
(2) To obviate having exposed surfaces rough cut by wire and thus to ensure
greater resistance to percolation of water.
(3) To provide free and efficient means of escape for water.
In the accompanying drawing Fig 1 is a longitudinal section on the lines A. B.
C. D of Fig 3, of two adjacent tiles one overlapping the other.
Fig 2 is a cross section on line E. F. of Fig 3 and shewing also the lower edges
of the two upper tiles in that figure. Fig 3 is an isometrical view of five tiles
shewing the manner in which they overlap.
These tiles are made of bands of clay, each tile having a flat main portion b
having at the upper surface near one end a raised part or bulge c with a recess c¹
in the under face thereof. Each longer side of the tile is formed with a groove and
tongue, fillet or projection as usual, and as indicated at d and h.
The lower face of the tile may moreover be provided with two projections e, or
there may be only one which may be arranged centrally. The projection or rib e
is not however, absolutely essential, although it can be pressed simultaneously with
the parts c. c¹ therefore it may, on the other hand, be dispensed with, and not
formed at all.
Such tiles as described above are manufactured continuously in the form of clay
bands issuing from power presses. The superfluous portions of the projections e
are cut away by a wire, while the portion c. c' is pressed out between an upper
and a lower mould into the desired shape, and at the same time the tile is cut to
the required length by a wire upon the cutting table.
The tiles are placed so as to overlap one another in the manner shewn in Figs 1
and 3. The projections e are hung upon the roof laths f (see Fig 1) in such a
manner that the recess c¹ of one tile covers the ridge formed by the groove and
tongue or fillet joint hd of the two tiles below. Any water running off the
surface b of the upper tile is diverted by the bulge c on to the surfaces b. b below,
whilst, moreover, any water entering the joint h. d on an upper tile runs away on
the surface b of the next lower tile.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The improved roofing tile manufactured continuously in the form of bands
issuing from power presses, this roofing tile having parallel sides, and being

page_text: constructed with a flat main portion b a pressed out or raised part or bulge c, and
recess c¹ 50 as to be capable of overlapping adjacent tiles similarly formed,
substantially as shewn in and described with reference to the accompanying
drawings.
