Improvements in Machinery for the Manufacture of Roofing Tiles.
I, ABRAHAM WEIL, of Steinheim, Westphalia, in the Empire of Germany,
Merchant, 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 machinery for the manufacture of roofing tiles having
upper and lower overlapping fillets.
In the accompanying three sheets of drawings
Figure 1 is a longitudinal section of the upper part of a machine, constructed in
accordance with my invention, for the purpose of forming the upper overlapping
fillets on the green or unbaked body of the roofing tile.
Figures 2 to 7 show another arrangement of the machinery for the same purpose,
Figure 2 being a vertical section, Figure 3 a plan and Figures 4 to 7 separate views
of parts of the same machine.
Figures 8 to 11 show the moulding plate, and mould lining for forming the lower
overlapping fillets which are provided with a projecting tongue, Figure 9 being a
section taken on line z z¹ of Figure 8, and Figure 11 a similar section with the
corresponding part of the tile shewn in dotted lines. Figures 9 and 11 are drawn to
a larger scale than Figure 8.
Referring to Figure 1 it will be seen that the mould 7 with the mould plate
belonging thereto, for the formation of the underside of the roofing tile is contained
within the mould form 6, and that the main body of the unbaked roofing tile 8 is
carried by this mould plate. The hopper 9 is connected with a bridge 10 on which
is pivotted a bell-crank lever 11. Below the bridge 10 is arranged the plate 12
which rests on the tile 8 and is used in the formation of the upper overlapping fillets.
It is provided with guide screws. 13 which move in the guide slots 14 of the
bridge 10. The plate 12 is connected with the bell-crank lever 11 by means of a
pin 15. When the hell-crank lever 11 is moved in the direction of the arrow 16 the
plate 12 is moved in the direction of the arrow 17 so that the tile with its overlapping
fillets 3 is free to be pushed out by any suitable means. In Figure 1 the apparatus
for the production of the recesses in the lower overlapping fillets is omitted for the
sake of clearness because the figure only relates to the upper part of the machine.
In the arrangement of the machine shown in Figures 2 and 3 the apparatus for
the production of the recesses in the lower overlapping fillets is also omitted for the
sake of clearness.
The brackets 21 fixed to the frame 20 carry the guide rods 22, on each of which
is placed a movable slide 23. The upper part of each of the slides 23 terminates in a
horizontal plate 24, on which is fixed the bridge 25 by means of which the two slides
23 are connected together. Each slide 23 is also provided with a downwardly
projecting arm 26. To each bracket 21 is pivotted a two armed lever 27 which is
coupled by the connecting rod 28 with the arm 26 of each slide. On the plates 24
of the slides 23 is mounted movably the hopper 29 with its slide bars 30 guided by
the slots 31 and guide bolts 32. The hopper 29 can consequently be moved, to a
certain extent, to and from the bridge 25 notwithstanding that both parts remain
connected with the slides 23. This movement is effected by means of the following
arrangements :-
Each slide bar 30 is furnished with an arm 33 which is connected with the
lever 34. This lever 34 is also connected with the bridge 25 by means of the
1.1 25

page_text: The method of forming the recess a 2 is shown clearly in Figure 11, where-
I is the mould-plate as shown in Figure 9. a 5 represents the material forming the
tile at that part, which material is placed on the mould-plate when the slide a 4 is.
withdrawn into the position shown in dotted lines, so that the broader part a¹ of
the fillet a is at first filled in solid then the slide a 4 is pressed outwards by hand
or by suitable mechanism into the position shown by full lines, thereby forming the
recess a 2. Then when the tile has been pressed by the machinery shown in
Figures 1, 2 and 3, for example, the slide a 4 is withdrawn into the position shown.
by dotted lines, and the tile can then be removed from the mould plate.
Furthermore the mould-plate is shaped at the truncated corners 4 and 4* to fit into-
the mould lining 5, see Figure 10. The object of these truncated corners is to furnish
the roofing tile with angular off-set jointing edges.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First. In a machine for forming the overlapping fillets on roofing tiles the plate 12-
and the bell crank lever 11 pivotted on the bridge 10, so combined and arranged that the
said plate is moved diagonally downwards into the working position by the movement of
the bell crank lever in one direction, and diagonally upward into the elevated position
by the movement of the bell-crank lever in the opposite direction, substantially as.
described with reference to Figure 1 of the drawings.
Second. In a machine for forming the overlapping fillets on roofing tiles, the two-
plates 37 and 38 connected together movably with reference to one another, by means
of screws, the plate 38 being provided with a slotted bolt which is moveable vertically
in a box or socket 36 connected with the bridge 25, an eccentric 44 operated by a
lever 42 pivotted to the box or socket 36, and a pin or projection 45 fixed to the.
eccentric 44, and taking into a slot 47 in the plate 37, combined, arranged and
operating so as to produce firstly a movement of the lower plate 37 towards the right,
and secondly an elevation of both plates together, substantially as described with
reference to Figures 2 to 7 of the drawings.
Third. In a machine for forming the overlapping fillets on roofing tiles, the rigid
connection of the bridge 25 with the two slides 23, and the adjustable arrangement of
the hopper 29 on the slides 23 in such manner that the hopper can be moved by
means of a link 35 and lever 34 to or from the bridge 25 substantially as described
and for the purposes specified.
Fourth. In a machine for forming the overlapping fillets on roofing tiles the levers 27
connecting rods 28, and slides 23, so combined and arranged that the slides 23, the-
hopper 29 and the whole groove-forming apparatus for the upper overlapping fillets
can be moved by means of the said levers 27, substantially as described with reference.
to Figures 2 and 3 of the drawings.
Fifth. A mould-plate for forming the underside of a roofing tile, having a hollow
impress 2 formed on the underside thereof for the purpose of guiding a slide which is
inserted through an opening in the vertical wall of the mould-plate for making the
recess or groove in the lower overlapping fillets, whereby the base of the groove is
brought even or flush with the lower surface of the roofing-tile, substantially as.
described with reference to Figures 8, 9, and 11 of the drawings.
