Improvements in and relating to Dies and Moulds for the
Manufacture of Flanged Dutch Tiles and other Stove-parts,
and similar Articles.
I, MAXYMILIAN HARCZYK, of 7 Krakauer Vorstadt, Warschau, in the Province
of Polen, Empire of Russia, 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 an improved press-mould for the manufacture of Dutch
tiles and other stove-parts provided with flanges. The purpose of my invention is
to manufacture such articles from powdered materials by exposing the latter to
pressure, in such a manner, that the body, or tile proper, is pressed but once, the
flange, however, is pressed twice, as will all be more fully described hereinafter.
In order to make my invention more clear, I refer to the accompanying
drawing, in which similar letters denote similar parts throughout the different
views, and in which :
Fig. 1 is a vertical longitudinal section through the press-mould, taken on
line 14-15 of Fig. 3,
Fig. 2 is a vertical cross-section through the same, taken on line 16-17 of
Fig. 3.
Fig. 3 is a plan of the mould,
Fig. 4 is a detail of the same,
Fig. 5 is also a detail, drawn on a larger scale.
Figs. 6-11 represent the various stages occurring in forming a Dutch tile by
means of the above press-mould.
Figs. 12 & 13 represent two stages occurring if the several parts of the mould
are employed in another order.
Referring to Figs. 1-5, a designates a slide forming the lowest part of the
mould, and adapted to carry the other parts of the same between the cheeks of a
press. b is a flat frame resting on slide a, and forming with the latter a shallow
vessel adapted to receive the material c for the tile proper, Fig. 6. d designates a
bollow die embracing another die d', and forming with the latter a space adapted
to receive the material c¹ for the flange (Fig. 8). The parts d and d' thus form a
die as well as a mould. Both parts are firmly connected by means of a wedge e
(Figs. 1 & 2) provided with dove-tails, and having two cut-outs e!e opening
downwards directly over the space d' afore mentioned. Into this space may be
lowered a bipartite die ff, Figs. 1-5; each half of this die is cut away at
give room for the wedge e.
to
If, now, frame b, Fig. 6, has been filled with the powdered material, die d d' is
put upon the latter (Fig. 7) and is firmly connected with slide a by any suitable
means. Space is also filled then with the mass, Fig. 8. The bipartite die f¹ fƒ'
is put upon the mass c', and the whole is brought into a press, the upper platen of
which is shaped as shown at g in Figs. 1 & 2. This platen is provided with a
groove gl adapted to take over wedge e, if the platen is lowered, or pressed down
upon die respectively, Figs. 1 & 2.
Portion of the mass is, thus, compressed, and turned into a comparatively solid
body, i.e. the flange of the Dutch tile or other stove-portion just manufactured.
(Compare the hatched lines indicating the portions c and c² of the material in
Figs. 9 & 10). As soon as dies f¹ have entered the space d' completely, Fig. 10,
the fast connection between the mould or stamp d d' and the slide a is broken.
Both dies (f'f' as well as d d¹) are pressed down now simultaneously upon the

page_text: material contained within framę b, (Fig. 11), so that also this material (c) is
compressed, and turned into a comparatively solid body, i.e. the tile proper.
It will
be observed, that also the flange is still further compressed during this operation,
or in other words, is compressed a second time.
Instead of pressing the flange at first, and the body of the Dutch tile after-
wards, I may reverse these operations, as shown in Figs. 12 & 13. In this case, I
proceed as follows:
After frame 6 has been filled, die d d' is put upon the material; and pressed down
upon the same (Fig. 12). Space d' is filled then with the material requisite for the
flange (Fig. 13), and the bipartite die f' f' is pressed down as far as possible
(Fig. 11), when the whole operation will be completed.
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 the manufacture of flanged Dutch tiles, stove-parts and the like, the use of
a compound die to shape the body of the tile and to form the mould for the flange.
thereof, substantially as herein before specified.
2. In the manufacture of flanged Dutch tiles, stove-parts and the like, the
combination of an inner and outer die adapted to produce the body of the tile and
to form a mould for the flanges with a die or dies for pressing the said flanges, all
substantially as herein before specified.
3. In the manufacture of flanged .Dutch tiles, stove-parts and the like, the
combination with a mould to receive the body of the tile of a compound die
consisting of an outer die d and an inner die d', the said compound die forming the
mould for the flange or flanges of the article and to receive a die, made in two or
more pieces f¹ƒ³, adapted to be pressed down into the compound die independent
of the latter, all substantially as herein before described and shown by the
accompanying drawings.
Dated this 10th day of July 1894.
