Improvements in Roofing Tiles, and in Apparatus for
Manufacturing same.
1, GUSTAV SCHULZE, of Eisleben, Saxony, in the Empire of Germany,
Machine Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to roofing tiles possessing the quality of adhering fast to
the roof, that is to say, being storm proof, without any nails for fixing being
applied.
This purpose is attained by the channelled tile represented in Figs. 1 to 10,
being plans and sections, of the annexed drawing, in Figs. 11 to 16, being plans
and sections, apparatus for producing such tiles being illustrated.
The principal feature of this new tile is a quadrangle having three truncated
points, of which those marked a form the touching or meeting surfaces for two
adjacent tiles. (Figs. 1, 4, and 7.)
On the top face of the tile a groove running parallel with the two outer sides
is impressed, which groove toward the outside is limited by a rib c projecting a
little over said groove b, and which rib c on its part has a cut away portion d.
This hollow or cut away portion d serves as the recess for receiving the mortar
in order that the roof may in fact be capable of being bound together. The
rib e arranged inside of the tile serves to engage into the groove b (Fig. 4)
whereby the joint closure, illustrated in Fig. 9, is attained. For binding the
meeting surfaces a of two adjacent tiles, the mortar-groove is provided. (Figs. 1,
7 and 10.)
In order to protect the roofing from being lifted off by storms, each tile
possesses at its underside, besides the attachment nose g, a conically projecting
nose h. This nose h, as may be seen from Fig. 7, always grips underneath two
adjacent tiles. This arrangement lias, apart from the above mentioned, the
further special advantage that even a broken tile is not allowed to drop off so
that accidents are entirely avoided.
The star or boss in the centre of the tile serves to increase its durability.
For making these tiles a special moulding-table is constructed, which is illus-
trated in Figs. 11 to 16, the method of manufacturing being as follows;—The
lid having been lifted up, according to Fig. 12, or pushed sideways, as in
Fig. 11, a moulding plate is placed into the moulding box; thereupon the
displaceable lever m is, by the aid of the rod n, brought into the position shown
in Fig. 12 and the moulding box filled up with clay or cement or other material,
stamped fast and rubbed smooth. By pressing the lid k upon it the grooves /
and d are formed as seen in Figs. 12 and 14, thereupon the material partially
raised by the impression is sinoothed by the aid of a trowel; after now the rod n
has been pushed forward, the lever m arrives in the position shown in Fig. 13.
Thereby the moulding plate is set free and by pressing down the treadle o five
vertical props p are raised by the medium of a suitable lever device. Thereupon
the moulding plate is taken with the hands and put into a drying shelf. Fig. 15
illustrates the way in which the two lateral pins 9 produce a safe guidance for the

page_text: lid k, and Fig. 16 shows the method in which the conical recess f is produced
for receiving the mortar.

I, GUSTAV SCHULZE, of Eisleben, Saxony, in the Empire of Germany,
Machine Manufacturer, 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 roofing tiles possessing the quality of adhering fast
to the roof, that is to say, being storm proof without any nails for fixing being
applied.
This purpose is attained by the channeled tile represented in plans and sections
in Figs. 1 to 10 of the drawing filed with the Provisional Specification. The
apparatus for producing such tiles being illustrated in Figs. 11 to 16 in plans and
sections.
The principal feature of this new tile is a quadrangle having three truncated
points, of which those marked a form the touching or meeting surfaces for two
adjacent tiles (Figs. 1, 4 and 7).
rib c
On the top face of the tile a groove b running parallel with the two outer
sides is impressed, which groove towards the outside is limited by a
projecting a little over said groove band which rib c on its part has a cut away
portion d. This hollow or cut away portion d serves as the recess for receiving
the mortar in order that the roof may in fact be capable of being bound
together. The rib e arranged inside of the tile serves to engage into the groove b
(Fig. 4) whereby the joint closure, illustrated in Fig. 9 is attained. For binding
the meeting surfaces a of two adjacent tiles the mortar-groove f is provided.
(Figs. 1, 7 and 10.)
In order to protect the roofing from being lifted off by storms, each tile
possesses at its underside, besides the attachment nose g, a conically projecting
nose h. This nose h as may be seen from Fig. 7 always grips underneath two
adjacent tiles. This arrangement has, apart from that above mentioned, the further
special advantage that even a broken tile is not allowed to drop off so that such
accidents are entirely avoided.
The star or boss in the centre of the tile serves to increase its durability.
For making these tiles a special moulding table is constructed, which is
illustrated in Figs. 11 to 16, the method of manufacturing being as follows:-The
lid having been lifted up according to Fig. 12, or pushed sideways as in Fig. 11,
a moulding plate is placed into the moulding box; thereupon the displaceable
lever m, by the aid of the rod n is brought into the position shown in Fig. 12 and
the moulding box filled up with clay or cement or other material, stamped fast
and rubbed smooth. By pressing the lid k upon it the grooves b and d are formed
as seen in Figs. 12 and 14, thereupon the material partially raised by the impression
is smoothed by the aid of a trowel; after now the rod n has been pushed forward
the lever m arrives in the position shown in Fig. 13. Thereby the moulding plate
is set free and by pressing down the treadle five vertical props p are raised by
the medium of a suitable lever device. Thereupon the moulding plate is taken
with the hands and put onto a drying shelf. Fig. 15 illustrates the way in which

page_text: the two lateral pins 9 produce a safe guidance for the lid k and Fig. 16 shows the
method in which the conical recess f is produced for receiving the mortar.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) A tile made of any convenient material, the characteristic novelty consisting
in its having at its bottom side a conical shaped projecting nose (h) gripping
beneath two adjacent tiles, two recesses (f) presented at the meeting faces of tiles
lying beside each other, and two recesses (d) presented on the meeting faces of
tiles lying above one another.
(2.) A machine for producing tiles of the kind described in Claim 1 having a
perforated moulding plate in connection with a push lever device, the lever m of
which for producing the nose (h) passes through the orifice of the moulding plate
into the mould, whilst the recesses (f and d) for the mortar and the groove (6) are
stamped by means of a lid (k), capable of being moved and down.
