COMPLETE SPECIFICATION.
Improvements in the Manufacture of Ceramic Ware, and in
Machinery or Apparatus for the same.
We, CONRAD PAULUS, Civil Engineer, of Posen, and HERRMANN HEIM,
Porcelain Manufacturer, of Kolmar near Posen, both in Germany do hereby
declare the nature of our said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
Our invention relates to the manufacture of porcelain, pottery, and ceramic ware
generally, which have hitherto been wrought by hand upon the potter's wheel;
and its object is to effect the same by means of a mechanically operated tool or
instrument and other apparatus in combination therewith.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a side view of a machine constructed according to our invention, partly
in section.
Fig. 2 is an end view of a part of the apparatus, drawn to a larger scale.
Fig. 3 is a plan view of parts of Figs. 1 and 2.
Figs. 4 and 5 are detail views of parts of the moulding appliances.
Fig. 6 is an enlarged detail section, on the line of Fig. 1.
The framework A of the machine may be fitted with one, two, or more vertical
revolving table spindles a; one being shown in Fig. 1, and two in Fig. 2. The
spindles a are driven by belts from wheels on the shaft w. c is a horizontal
shaft mounted in bearings b, as shown in Figs. 2 and 3. e is a worm-wheel fast on
the shaft, and gearing with the worm f fast on the spindle d, the latter being
driven by belting, whereby the wheel e is caused to revolve slowly.
On the shaft c are fitted (according to the number of mechanics attending to the
potters' wheels); a number of radial arms; or plates h. Each of these arms are
fitted with adjustable rods g', g³, g³.
The radial distances of the outer ends of these rods act as so many points for
operating the levers k, which levers act as holders to the moulding tools 1.
The lever k is pivoted at k¹ and carries a weight u to ensure its contact with the
rods ggg; and, when these are out of contact, the weight tends to lift the
moulding tool above the work m. A handle is provided for operating the lever
by hand, as required.
In consequence of the revolution of the worm-wheel e, the moulding tool 1, and
form m remain out of action until the rods g¹ 93 g, attached to the arm h, raise the
end of the lever k. This motion causes the moulding tool to come into contact
with the clay in the form m, pressing into the form, without the further aid of the
operator, who has only to arrange the filling and changing of the form on to the
stationary potter's wheel.
The rods 9 9' are formed with slots for adjusting the same, as shown in
Fig. 6. The arrangement of these rods permits of the adaptation and regulation
of the motions of the lever k and tool for the formation of large and small objects,
and the motions of the lever k being intermittent, a completely smooth formation of
the work is effected.

page_text: With the moulding or forming tool 1, a clearing or "wiping off" knive o is
connected, which projects above the mould form, occasionally operating so that
the pressed material is sharply cut off if the tool is pressed down into the material
to be shaped.
As shown in Figs. 4 and 5, the stripping knife v may be fixed at the side of the
moulding tool, whereby the operation can be effected as regulated by the slotted
bracket and bolt and nut t.
The above described arrangement of the mould exempts the worker from having
to strip or clean the form, thus facilitating the operation.
Another part of our invention consists in an arrangement for conveying water or
other liquid to the plastic material under treatment.
This consists of a cistern z, from which a pipe o leads to a cock n, the plug of
which is connected with the lever k, as shown in Fig. 3, by means of the link j.
From the cock n the pipe o' carries the water directly to the work. As the leverk
rises and falls, the cock n is closed and opened, whereby the water is conducted to.
the work as it is required.
Our invention is especially applicable to the formation of architectural work and
economical production, as a number of revolving table spindles a may be arranged,
so that each of the levers rise and fall in succession, thus affording a single
worker ample time during the "dwell" to attend to the setting up and removal of
the work without 'stopping the motive power.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1. The improvements in the manufacture of ceramic ware, and in machinery or
apparatus for the same, substantially as and for the purposes described.
2. In the manufacture of ceramic ware, the application and use of a moulding
tool 7, operated by the lever k, actuated by rods g' 93 and 9', or equivalent devices,
substantially as hereinbefore described and illustrated by the drawings.
3. In apparatus for the purposes aforesaid, the combination therewith of the
water feeding appliances, operated by the lever k, link j and cock n, substantially.
ns herein before described and illustrated by the drawings..

4. In apparatus for the purposes aforesaid, the application and use
stripping knife v, substantially as and for the purpose described and illustrat
the drawings.
