the like Solid Earthenware Articles.
I, KARL THOMANN, Manufacturer, of 40 Merseburgerstrasse Halle on the Saale,
Germany, 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 :-
The following invention relates to a machine for producing tiles or the like solid
earthenware articles and this machine consists of a circular revolvable press table
with colour and material feeding apparatus arranged over same also a press and
mould releasing contrivance.
The object of the machine is the automatic colouring, forming, pressing and
eventual throwing out of the mould of flooring slabs, building stones, blocks, tiles
and the like.
In the accompanying drawings the said invention is represented in its essential
parts and is hereinafter particularly described with reference to said drawings and
finally pointed out in the claims:-
In the drawings hereunto annexed :—
Fig. 1 is a plan of the machine.
Fig. 2 is a vertical section on the line x-y Fig. 1 looking in the direction of
the arrow v.
Fig. 3 is a vertical section on line u-z Fig. 1 looking in the direction of the
arrow w.
Fig. 4 is a local sectional elevation on line p-s Fig. 1.
Fig. 5 is a part plan of the press table with the contrivance for loosening the
pressed tiles etc. in their moulds.
Figs. 6 to 17 show various details of the construction which are hereinafter fully
described.
The construction of the apparatus is essentially as follows:-
The driving shaft 1 has firmly fixed thereon the driving wheel 2 and the bevel
cog wheel 3.
The bearings of the shaft 1 are at 4, 5, 6 and 7 underneath the mould table
hereinafter described.
The bevel wheel 3 gears into a second bevel tooth wheel 8 carried on the vertical
shaft 9 which is mounted in the frame or support 10 and by means of the arrange-
ment of the bevel cog wheels and gearing 11, 12, 20, 13 and 14 rotates the
Archimedean screws 15.
These screws 15 are situated in the sloping outlets of the circular colour
funnels 18-and supported on the table 17 by means of bracket 16 fastened in the
supporting frame 10.
These outlets of the funnels 18 open on the distributing table 19 which is divided
into as many compartments as there are colour funnels in operation. Through the
toothed wheel on the shaft 20 and the small toothed wheels 21 gearing therewith
the distributors 22 rotating in the separate compartments of the distribution table 19
are set in motion.
From the distribution table 19 the separate distribution pipes or tubes 23 lead
into the mould pipe 24.
There is further fixed upon the driving shaft the bevel cog wheel 25 which by
means of suitable connections 26 and 27 (see Fig. 3) set the Archimedean screw 28
in motion which delivers the material (for forming the tile etc.) from the hopper 31
to the table 30 and thence to the delivery shoot or pipe 61.

page_text: 32 is the circular moulding table which is supported and free to revolve hori-
zontally in the four columns 33 with the anti-friction rollers therein 34 and 35 (see
Figs. 10 and 11) and for the sake of clearness I shall hereinafter refer to this
table 32 as the "press table."
This "press table" carries the moulding boxes or moulds 36 (see Figs. 5 to 9).
These moulding boxes 36 are divided in two parts of which the under part is solidly
.connected to the press table the upper part on the contrary is so arranged as to be
movable in the direction of the radius of the press table.
37 and 38 are contrivances by means of which the said movable part of the
moulding box is moved inwards or outwards upon passing as the press table
rotates.
39 (Fig. 2) is a projecting arm or thumb on shaft 1 which by coming in contact
with the tappets or projections 40 turn the press table round by a step by step
motion as far as required at each movement.
Fig. 4 shows a contrivance by means of which the ready pressed tile etc. is
mechanically lifted out of the mould 36 on the false bottom or plate 41 and a
similar contrivance also operates under the colour conducting pipe 24 by means of
which raising contrivance the plate 41 is lifted up to pipe 24 so that the colour is
laid on in sharp outlines.
The contrivance Fig. 4 essentially consists of cams 43 and 44 fixed.respectively
upon the shaft 42 in the first mentioned case Figs. 3 and 4 (and upon shaft 1 in the
second case) which shaft and said cams thereon periodically raises the crown 45
with vertical pins thereon as shown so as to lift the plate 41 in the mould.
The pressing apparatus is as follows:-
46 is the guide frame or standard forming guideways to the cross beam 47
carrying the springs 48 and 49.
The beam 47 is moved up and down by the two excentric rods 50 and 51 actuated
by means of excentrics 52 and 53 on the shaft 1.
On the cross head 47 there is carried a plunger head or stamp 54 so arranged
as to be vertically adjustable and represented in local section in Figs. 12, 13 and 14.
55 (Figs. 2 and 12) is an adjustable contrivance on the head or stamp 54 to ensure
that, the latter enters truly into the mould and only to the required distance.
Figs. 13 and 14 show a spring arrangement for the head or stamp 54 the object
of which is that the latter after pressure from the cross bar 47 is effected-should
be again carried upwards.
57 and 58 are levers which being acted upon by the cross head press the head or
stamp downwards.
In order that the stamp or head 54 may exercise the required pressure according
to the material under treatment the said springs 48 and 49 may be vertically
adjusted upon the pillars 59 which carry same (see Figs. 1 and 2) or horizontally
adjusted in the slots 59* (see Fig. 1) or in other suitable manner.
The bottom half of the press table is supported at the point under the head or
stamp 54 by the support 60.
The working of the machine is as follows:-
The hoppers 18 are filled with various colouring materials, the hopper 31 with
mortar cement potters clay or the like, and the shaft 1 put in motion.
The pin mounted crown 45 presses the plate 41 against the colour conducting
tube 24 in which a tubular system corresponding with the ornament desired to be
imprinted on the made article is inserted which stands in connection with the
tubes 23 in position corresponding to the respective colours.
Then the crown 45 sinks and with it the plate 41 and the table (by the action of
the thumb 39 striking one of the arms 40) undergoes a movement of one step.
When the moulding box provided with colour patterns has arrived under the
material conductor 61 it is automatically filled with material and comes eventually
under the press 54.
When the material in the mould is pressed by the head 54 it next passes (with
the
press table) the rollers 37 and 38 (Fig. 5) and is thereby loosened from the

page_text: mould by the shifting (sliding) of the movable part of the latter on the bed of the
press table and then finally reaches the throw off apparatus Fig. 4 which lies under
the press table at the point marked A Fig. 1. Here the crown or device 45 lifts
the plate 41 and with it the ready pressed article thereon upwards out of the mould
and in such a manner that it can be removed by hand or as desired.
The same course of working is accomplished by each moulding box on the press
and the machine works automatically so that only the introduction of the colouring
matters and potters' materials etc. into their respective hoppers or holders requires
to be effected by hand.
In order to produce the various ornamental colourings the tube 24 can readily be
provided with a pattern tube for conducting the colours corresponding with the
desired pattern.
Figs. 16 and 17 show the pressed slabs tiles or articles produced in and by my
hereinbefore described machine.
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 :-
:-
