improvements in Machines for the Manufacture of Earthenware and
Stoneware Articles.
I, VIKTOR VALDEMAR CHRISTOFFER HANSEN, of Godthaabsvej, Copenhagen,
in the Kingdom of Denmark, Manufacturer, do hereby declare the nature of this
is to be performed to be particularly
invention and in what manner the same
described and ascertained in and by the following statement :-
This invention relates to a machine by means of which a great number of
earthenware or stoneware articles inay be manufactured at one time, and which
requires very little attention.
J
Fig. 1 of the accompanying drawings is a side elevation, and Fig. 2 an end
elevation, of a machine according to this invention; Figs. 3 & 4 are respectively
a longitudinal section and a cross section thereof; and
Figs. 5, 6 & 7 show the shaping-portion of the machine in side elevation, end
elevation, and plan respectively.
The upper part of the machine, which is for the purpose of filling the moulds, is
and to

secured to a frame f adapted to be raised and lowered by means of nuts
It comprises two

longitudinal boxes a, each containing two rollers b, arranged to be turned in
opposite directions, by means, for instance, of belt or wheel-gearing. The axle
carrying the fast and loose pulley for the belt for driving these rollers may be
raised or lowered by means of worm-gear or other suitable device so as to be made

are fixed a number of hoppers e and under each hopper there is an annular opening d
in the bottom of the corresponding box. Underneath the boxes there is an
arrangement k for cutting off, by means of strings, the required lengths of the
earthenware or stoneware material. Scrapers are provided for preventing the
material from being carried up again by the rollers b.
The lower part of the machine, which is a fixture, is provided under each
The discs m corresponding to each
hopper c with a disc m carrying a mould n.
longitudinal box a are secured on axles arranged to be rotated by means of bevel
or worm gearing, from one common shaft that forms or is in connection with the
main driving shaft of the machine.
Above the lower part of the machine and carried by columns is a shaping-
apparatus (Figs. 5, 6 and 7), that may be lowered over the moulds when the upper
or feeding part of the machine is moved aside. The shapers o are fixed on
bearers p, which, by means of a screw and a hand-wheel q may be moved slightly
sideways. The raising and lowering of this shaping-apparatus may be effected for
example, by means of toothed-wheels that gear into racks on the apparatus and may
be rotated by means of a chain as indicated in Figs. 5, 6, and 7.
The operation of the machine is as follows:-
The upper or feeding part of the machine having been placed just over the lower
part, the moulds are filled with the earthenware or stoneware material. The
driving belt of the feeding part is now placed upon its fast pulley and by means
of the rollers 6 the earthenware or stoneware material is pressed out in the form of

tubes through the annular openings in the bottoms of the boxes a.
tubes have acquired the necessary length, the rollers are stopped by transferring
the belt to the loose pulley; and the tubes are then cut off by pulling the handle

mould n, whereupon the upper part of the machine is pushed aside. The lower
part is now put into operation and the shaping apparatus lowered, the position of
the shapers being suitably adjusted by means of the screw and hand-wheel q to
give the articles the desired shape.
When the axles carrying the moulds are driven by means of bevel-wheels, as
shown, they may be easily lifted out and one or several of them may in this way, if
desirable, be kept out of action.
The discm may be furnished with diametrical grooves r in their surfaces and the
moulds n with corresponding grooves s in their undersides. When these grooves
are opposite one another a suitably shaped stick or rod may be inserted in the
openings thus formed and all the moulds lifted out together and carried to the
drying chamber where the finished earthenware or stoneware articles may be
turned out upon a table to be dried.
Having now particularly described and ascertained the nature of the said inven-
tion I declare that what I claim is :-
1. A machine for the manufacture of earthenware and stoneware articles,
comprising several axles adapted to be rotated by one common shaft the said
axles carrying discs m upon which are secured woulds n arranged to be filled with
earthenware or stoneware material from a laterally movable feeding, apparatus
having two rollers 6 arranged to rotate in opposite directions and an annular
space d over each mould, and a vertically adjustable shaping-apparatus carrying
adjustable shapers o, one for each mouli, substantially, as and for the purposes
described.
2. In a machine of the kind specified in the preceding claim, the arrangement of
corresponding grooves, and s. on the surfaces of the discs carrying the moulds and
the undersides of the moulds adapted for the insertion of a stick, or rod by means
of which the moulds may be lifted simultaneously, substantially as described.
3. My improved machine for the manufacture of earthenware and stoneware
articles, constructed, combined, and operating substantially as, hereinbefore
described with reference to and, shown in the accompanying, drawings.
Dated this 19th day of September 1895.
