IMPROVED AUTOMATIC APPARATUS OR MACHINERY FOR THE MANUFACTURE OF POTTERY
Year: 1885

page_text: Manufacture of Pottery.
I, THOMAS WILLETT, of Brickhouse Street, Burslem, in the County of Stafford,
Potters Engineer, do hereby declare the nature of my Invention for "IMPROVED
AUTOMATIC APPARATUS OR MACHINERY FOR THE MANUFACTURE OF POTTERY," to
be as follows:-
This improved machinery consists of two vertical spindles to one of which
revolving motion is communicated by an endless band or in any other convenient
manner and which in turn by means of a strap gives revolving notion to the other
spindle. I communicate revolving motion from this last mentioned spindle by a
worm and worm wheel to a suitable cam upon a horizontal shaft-over or under
which cam is mounted one arm of a lever the other arm of which carries the
'profile" for forming article of pottery--and thus I operate the lever automatically
and bring the profile down intermittently on to the clay carried by the first
mentioned revolving spindle. In this manner I form or mould the clay into the
required shape. Instead of a single lever it will be obvious that the same shaft
which carries the cam can also carry two or more cams for operating other levers
and profiles.
6f
Instead of moulding as aforesaid I sometimes mount a disc or block made of
iron, wood or other suitable material at the head of the first mentioned spindle and
employ a profile fixed to the table or bench so as to project over the disc or block
and thus to shape the outside of the article being formed and against which the
clay is forced by means of a plunger or block corresponding in external form to
the shape of the inside of the article requiring to be moulded and affixed to the
aforementioned lever.
This plunger or block has besides its up and down motion a sliding movement
imparted to it by the cam to form the internal surface of the article: this
machine being useful for throwing such articles as flower pots, jars, bottles and
other similar articles.
In addition to the foregoing purposes this improved machine is useful for
forming bats in accordance with the invention described in the Specification of
Letters Patent No. 981 granted to me 8th March 1881 but this I do not claim as
forming part of the present application.

Improved Automatic Apparatus or Machinery for the
Manufacture of Pottery.
I THOMAS WILLETT of Brickhouse Street Burslem in the County of Stafford,
Potters Engineer 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:—
As illustrated by perspective view in Fig. 1. this improved machinery consists of
two vertical spindles a and b to one of which, revolving motion is communicated
by an endless band passing round the grooved pulley or in any other convenient
manner and which in turn by means of a strap c gives revolving motion to the
other spindle b. I communicate revolving motion from this last mentioned spindle
by a worm i and worm wheel j to a suitable cam d upon a horizontal shaft e over
or under which cam is mounted one arm of a lever f which is weighted as illustrated
and the other arm of which carries the profile g down intermittently on to the
clay carried in the mould k by the first mentioned revolving spindle. In this
manner I form or mould the clay into the required shape.
Instead of a single lever it will be obvious that the same shaft which carries
the cam, can also carry two or more cams m for operating other levers n and
profiles o as illustrated by perspective view in Fig. 2. The spindles p in this
case both receive their motion from the back vertical spindler by their respective
straps 8 and t.
The action of this double machine will be obvious from the illustration-the
cams being so timed or placed upon the shaft that as one profile o is down and
performing its function in the mould u, the other is up and vice versa; and hence
the operator can attend to a pair of moulds alternately.
In addition to the foregoing purposes this improved machine is useful for forming
bats in accordance with the invention described in the Specification of Letters
Patent No 981 granted to me 8th March 1881, but this I do not claim as forming
part of the present application.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
The combinations and arrangements of mechanism constituting automatic
apparatus for the moulding of pottery substantially as herein before described and
illustrated on the accompanying drawing.
