Improvements in Machinery for the Manufacture of Roofing
Tiles or Slabs.
I, CARL WICKE, of No. 28, Paraleelstrasse, Lehe, Hanover, in the Empire of
Germany, Builder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to machinery for the production of roofing tiles or slabs
of that kind in respect of which Letters Patent were granted to me dated the
24th day of December 1894, No. 25065.
In carrying the present invention into effect, a strong frame is employed upon
which is carried a suitable bed-plate supporting a matrix or die of the shape to be
given to the underside of the tile and around this matrix is arranged a strong
frame the whole constituting a form in which the material to produce the tile is
pressed as hereinafter described, the inner faces of the walls of the form, at the
upper part, being polished to give a good surface to the tile.
Upon the matrix or die and within the wall or frame is place.l a tin-plate or
other thin metal template which is of a shape to correspond with the matrix and
the material to form the tile is filled into the form to a suitable depth and
pressed into the template.
Above the form and mounted upon an axis of motion so that it is adapted
to turn back against a rest, is a device for forming the rabbet or water groove
in the upper side of the tile.
This device consists of a frame which is turned down upon the body of cement
to form the tile, and it is provided at its rear with upwardly projecting inclined
guides in which is mounted a tool in such manner that it will slide vertically and
longitudinally and this tool at its rear is provided with a handle so that it may be
forced down on to the cement, and at its front edge it is shaped with a rim or lip
adapted to enter the cement and form the undercut rabbet or water groove.
In order to obtain the necessary pressure for this purpose and to hold the slide
and frame in position upon the cement, a frame, shaped like a half diamond and
mounted upon a centre of motion and on its underside shaped to give the necessary
form to the tile, is turned down upon the cement, and this frame is furnished with
a crossbar upon which two levers, mounted upon axes of motion connected at their
rear ends and coupled at their front ends by a bar, are turned so that upon pressing
upon these levers the necessary pressure will be exerted through this frame to the
slide in order to depress the saine and indent the rabbet in the cement.
After the pressure has been thus applied a return motion is given to the slide by
means of suitable levers and the respective frames are turned back on their hinges
against the rest after which several lifting spindles carried by a table vertically
moved by means of a treadle and passing through the matrix litt the template and
tile out of the form, and it can then be removed to be dried and burned in the
usual way.
The pressing frame is furnished with pivotally mounted catches which engage
some fixed part of the machine whereby the same may be locked in position during
the pressing operation and small lateral slides are provided for the purpose of

page_text: making slotted indents in the sides of the tile and to receive storm fastenings to
hold the same in position and in the frame near to the front of the tile a small
slide is similarly employed to make a hole or indent to receive a further fastening.
The pressing frame is furnished with set screws hy means of which the degree
to which the same and consequently the rabbet slide may be depressed may be
regulated at will.

Improvements in Machinery for the Manufacture of Roofing
Tiles or Slabs.
I, CARL WICKE, of No. 28 Paralellstrasse, Lehe, Hanover, in the Empire of
Germany, Builder, 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 :-
My said invention relates to machinery for the production of ro fing tiles or
slabs of that kind in respect of which Letters Patent were granted to me dated
the 24th day of December 1894 No. 25065.
In carrying the present invention into effect, a strong frame is employed upon
which is carried a suitable bed-plate supporting a matrix or die of the shape to be
given to the underside of the tile and around this matrix is arranged a strong frame
the whole constituting a form or mould in which the material to produce the tile
is pressed as hereinafter described, the inner faces of the walls of the form, at the
upper part, being polished to give a good surface to the tile.
Upon the matrix or die and within the wall or frame is placed a tin-plate or
other thin metal template which is of a shape to correspond with the matrix and
the material to form the tile is filled into the form to a suitable depth and pressed
into the template by any ordinary means.
Above the form and mounted upon au axis of motion so that it is adapted to
turn back against a rest is a device for forming the rabbet or water groove in the
upper side of the tile.
This device consists of a frame which is turned down upon the body of clay or
cement to form the tile, and is provided at its rear with up varlly projecting
inclined guides in which is mounted a tool in such manner that it will slide
vertically and longitudinally and this tool at its rear is provided with a handle so
that it may be forced down on to the clay or cement, aud at its front edge it is
shaped with a rim or lip adapted to enter the clay or cement and form the
undercut rabbet or water groove.
In order to obtain the necessary pressure for this purpose and to holl the slide
and frame in position upon the clay or cement, a frame, shaped like a half diamond
and mounted upon a centre of motion and on its underside shaped to give the
necessary form to the tile, is turned down upon the clay or cement, and this
frame is furnished with a crossbar upon which two levers, mounted upon axes of
motion connected at their rear ends, and coupled at their front ends by a bar, are
turned so that upon pressing upon these levers the necessary pressure will be
exerted through this frame to the slide in order to depress the same and indent the
rabbet in the clay or cement.
After the pressure has been thus applied a return motion is given to the slide
by means of its handle or suitable levers and the respective frames are turned back

page_text: Figure 28. is an end view of a guide for another tool.
Figure 29. is a plan thereof.
Figure 30, is an edge view of the tool or slide intended to work in conjunction
with the guide to form a recess for another storm fastening, and,
Figure 31. is a plan thereof.
In the several figures, in which Figures 7. and 8. and 22. to 31. are drawn to an
increased and variable seale with relation to the other figures of the drawings, like
parts are indicated by similar letters of reference.
a. represents the frame of the machine which is furnished with a bed plate or
table a' and upon this table is removeably fixed a strong frame b. within which is
supported a matrix or die &' of the shape required to be given to the underside of
the tile c. the whole constituting the form or mould in which the material to
produce the tile is pressed as hereinafter described, the inner faces of the walls of
the form being polished to give a god surface to the tile.
Upon the matrix or die & and within the wall or frame b. is placel a tin plate
or other thin metal template which is of a shape to correspond with the
matrix b', and the material c. to form the tile is filled into the form b. to a suitable
depth and pressed into the pattern of the template 62 by any suitable and ordinary
means.
Above the form &, and mounted upon an axis of motion d' carried by a short
standard d fixed with the table a' is a device d. for forming the rabbet or water
groove el in the upper side of the tile e. and this device is adapted to be turned back
upon its axis d' in the manner represented at Figure 6.
This device consists of a frame d, which is turned down upon the body of clay
or cement e. to form the tile, and is provided at its rear with upwardly projecting
inclined guides d as shown more particularly at Figures 13. and 14. in which is
mounted a tool d in such manner that it will by a compound movement slide
vertically and longitudinally in the guides d³ and this tool or slide d" at its rear is
provided with a handle d so that it may be forced down on to the clay or
cement c. whilst along both angles of its front edge the tool do is provided with a
rim or lip d adapted to enter the clay or cement c. and form the undercut rabbet
or water groove c¹.
In order to obtain the necessary pressure for this purpose and to hold the
frame d. and slide do in position upon the clay or cement c. a pressing frame e.
shaped like a half diamond is mounted upon an axis of motion e¹ carried by a short
standard e fixed with the table a', and this frame e. is upon its underside formed
with a projection shaped to press upon the clay or cement c. between the
lip d° of the slide d° and the frame d, and thus assist to give the necessary form
to the tile.
This pressing frame e. is as shown more particularly in Figures 2. and 17, to 19.
furnished with a crossbar e upon which are adapted to act two levers f. mounted
upon axes of motion / carried by the table a and at their front ends coupled
together by a bar so that by pressing upon the bar f' the necessary pressure
will be exerted through the levers, and pressing frame e. upon the slide do which
has been previously slidden forward on to the cement c. in order to depress the
same, and thereby indent the rabbet e therein, and at the same time the
projection of the pressing frame e. will compress that part of the clay or cement
beyond the lip d" of the slide d*.
After the pressure has been thus applied the levere fare turned back to their
normal position by their noses raising the frame e. with an upward and slightly
horizontal movement which is permitted by the elongated holes of the axis e a
return motion is then given to the slide d° by means of the handle do or it might be
by means of levers and the respective frames d. and e. are turned back on their
hinges d' or el when the frame e. will come against a rest g. and the frame d. will
rest against the frame e, as shown in Figure 6, after which several lifting spindles ¹
carried by a table h. vertically moved in the manner hereinafter described and
passing through perforations in the table a' and matrix & lift the template and

page_text: tile out of the form b. as shown at Figure 6, and it can then be carried away to be
dried and burned in the usual way.
The table h. receives motion from a treadle h³ which is mounted upon a centre of
motion carried by the frame a. and at its end is pivotally connected with a.
curved link pivotally connected with the table h, whilst the table h. is truly
guided in its movements by means of a vertical bar or shaft h at its ends fixed with
the frame a. and which passes through a box or bearing h² fixed with the underside
of the table h.
The frame or form b. has pivotally mounted thereon catches 63 which engage the
rabbet frame d. whereby the same may be locked in position during the pressing
operation and small lateral slides i. working in guide plates i fixed to the table a¹
are provided for the purpose of making slotted indents in the sides of the
tile to receive storm fastenings to hold the same in position upon the bearers of the
roof, and on the rabbet frame d. near to the front of the tile a small slide d' is
similarly employed to make a hole or indent in the tile c. to receive a further
storm fastening.
The slide d is carried in a guide d³ mounted upon a small lateral projection d' on
the frame d. and in order that it may be better supported it passes through an
undercut groove d' formed in the upper side of the frame d.
The pressing frame e. is furnished with set screws e by means whereof the degree
to which the pressing frame e. and consequently the rabbet slide d will be
depressed may be regulated at will and it is also provided with steadying pins e
which enter corresponding holes d in the frame d. and thus hold the two frames
against the possibility of shifting with relation to each other during the pressing
operation.
Having now particularly described and ascertained the nature of my said inven--
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a machine for the manufacture of roofing tiles or slabs, the combination of
a frame or form to contain the body of clay or cernent to form the tile, a rabbet
frame hinged to turn down upon the clay, a slide mounted in inclined guides upon.
the rabbet frame and on its underside provided with a projecting rim or lip adapted
to enter the clay or cement and form an undercut rabbet or water groove therein,
means for depressing the slide and small slides for forming depressions in the clay
to receive storm fastenings, substantially as herein shown and described.
2. In a machine for the manufacture of roofing tiles or slabs, the combination of
a fratne to contain the body of clay or cement to form the tile, a rabbet frame
hinged to turn down upon the clay, a slide mounted in inclined guides upon the
rabbet frame and on its underside provided with a projecting rim or lip adapted to
enter the clay or cement and form an undercut rabbet or water groove therein, a
pressing frame hinged to turn down upon the rabbet frame and on its underside
provided with a projection adapted to press the clay between the lip of the slide
and the form and with set screws or equivalent means for bearing upon the slide in
order to depress the same and form the undercut rabbet or water groove in the clay
and a lever or other means for depressing the pressing frame, substantially as
herein shown and described.
