Improvements in Machinery for Manufacturing Cups and other
Articles in Pottery-ware.
I, WILLIAM BOULTON, of Burslem, Staffordshire, Engineer, do hereby declare the
nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement :-
This invention relates to certain improvements in machinery for manufacturing
cups, bowls, mugs, jars, plates, saucers, horticultural ware and other articles in pottery;
the improvements consisting in the application, in combination, of a series of internal
or external shaping profiles on a counterbalanced jolley-arm common to the series
and capable of receiving vertical reciprocating and lateral turning movements in such
a manner as that two or more articles can be simultaneously made in the one machine,
and as that a lateral thrust may be given to the profiles for consolidating and the better
finishing the articles being made and which will also the more readily permit of
such articles being made as are required to be narrower at the top than at the bottom;
with an automatically operating vertically and horizontally reciprocating table,
adapted in its vertical movements to lower the moulds charged with clay into the
jigger-heads and to raise the moulds and formed articles from out of the jigger-heads,
and in its horizontal movements to remove the moulds and formed articles from above
the jigger-heads to a table for removal, and to simultaneously carry other moulds
charged with clay to above the jigger-heads so that on the next lowering of the table
the moulds charged with clay will be lowered into the jigger-beads and the other
moulds containing the previously formed articles will be left supported by the work-
bench ready for removal and replacement by other moulds charged with clay; and
with automatically acting scrappers for cutting off the scrap or surplus clay projecting
from the tops of the moulds containing the formed articles prior to their being raised:
so that in such operations the articles formed are not handled by the attendant, all
such motions of the parts being automatically effected.
The improved apparatus is illustrated on the accompanying drawings in front
elevation in Fig. 1, in side elevation in Fig. 2, and in plan view in Fig. 3.
In accordance with the present improvements, I apply to a suitable frame 4, any
convenient number of upright spindles 5, each of which is supported in a suitable
footstep 6, and in an upper part of the frame, as at 7, and has keyed on it a grooved
or other pulley 8. Around the series of such pulleys, there is passed an endless cord
or the like 9, which is also passed around and is actuated by a grooved or other
pulley 10, fast on a main driving spindle 11, which is supported in like manner to the
spindles 5. On the spindle 11, there is keyed a worm 12, which actuates a worm
wheel 13, keyed on a cross shaft 14, which is supported in bearings 15, bolted to the
frame 4. Each of the spindles 5, at a part above the frame 4, is fitted with an iron
or other metallic head 16, adapted to carry a plaster mould 17, conformable in shape
to that of the article to be made.
Above the frame 4, there is also arranged a counterbalanced jolley-arm 18, common
to the series of moulds 17, and to the fore side of which is attached in any suitable
manner the appropriate number of profiles 19, one for each mould.
These profiles may be variously shaped and used according to the ware to be pro-
duced; when manufacturing saucers plates and the like either externally or internally
profiles may be used.
The jolley-arm is carried by a spindle 20, supported in a bracket 21, and can bo
turned to a slight extent about such spindle as a centre as and for the purpose herein-
after indicated. The jolley-arm is also capable of being vertically reciprocated about a
horizontally disposed centre 22. The downward movement of the end of the jolley-arm

page_text: carrying the profiles about its centre 22, is effected by a cam 23, on the shaft 14,
thrusting up the counterbalanced end of the jolley-arm, thus causing the profiles to bo
thrust down into the moulds 17, to shape or form the clay while being spun around
by the revolving moulds; and the required slight extent of lateral turning movement
of the jolley-arm and profiles about the spindle 20, is effected by a bevilled extension 24,
from the cam 23, which at the proper time comes into contact with a like formed
part 25, on the side of the jolley-arin and thus turns it to a slight extent about the
spindle 20, as a centre, as indicated by the arrow 56, in Fig. 3, and the profiles being
turned to right angles of their indicated position, forces their edges nearer to the
mould as desired; or the same object can be effected by forming the centre of move-
ment of the jolley-arm as a universal joint so that it can be turned sideways as well as
up and down about a common centre; the special object of this provision is to
consolidate the clay in the mould and to give a more even and better finish to the
articles being made.
As soon as the articles in the moulds are formed the cam 23, ceases to operate the
jolley-arm, which, being counterbalanced, thereupon automatically raises the profiles
from out of the moulds and their contents.

revolving moulds.

The surplus clay projecting from the tops of the moulds is then removed by
"scrappers" consisting of arms 26, fitted with cutting wires or knives 27, for removing
or entting the clay from off the tops of the moulds. The "scrappers are carried by
a cross-shaft 28, supported in brackets 29, carried by the jolley-arm and are actuated
by a small cam 30, on the shaft 14, which causes a series of connected levers and
rods 31, 32, to raise the superposed ends and consequently to depress the acting ends
of the "
scrapper arms 26, so as to remove the surplus clay from off the tops of the
As soon as the formation of the articles is thus finished, the series of moulds 17, is
lifted from out of the jigger heads 16, on the spindles 5, by means of a frame or
table 33, which is fitted with a series of rings 34, adapted to receive and carry the
moulds, and is, at the appropriate times, raised, lowered and horizontally traversed as
hereinafter described. The rising and falling movements of the table 33, are effected
by a cam 35, keyed on the shaft 14, operating a lever 36, centred on a cross-shaft 37,
supported in bearings 38, carried by the frame 4, the lever 36, being connected to the
frame of the table by rods 39, worked in guide tubes 40, supported by the frame 4,
and carrying runners, 57, engaging with side guiding bars 58, with which the
table 33 is adapted. In the rising movements of the table its rings 34, catch under the
projecting rims of and raise the moulds 17, together with the formed articles therein
from out of the jigger-heads 16. The table and all it carries are then automatically
traversed laterally so as to bring the other moulds charged with fresh clay to over the
jigger-heads, simultaneously removing the moulds containing the already formed
articles to over a lateral extension 59, of the work-bench, whereupon the table is
automatically lowered by the means aforesaid, leaving the already made articles resting
on the workbench, and lowering the freshly charged moulds into the jigger-heads on
the revolving spindles, and as soon as this occurs the profiles are lowered as aforesaid
and the clay in the moulds in position is consequently shaped, the process of forma-
tion thus alternating with the lateral movement of the table 33, to the right and left.
The intermittent traversing movements of the table 33, are effected by means of a
segmentally toothed wheel 41, keyed on the cam shaft 14, and engaging with a toothed
pinion 42, keyed on a shaft 43, carried by bearings 44, bolted to the frame 4, a disc 45,
being also keyed on the shaft 43, and connected by a rod 46, to a lever 47, which is
centred at 48, and is connected to an arm 49, depending from the table 33, by a
rod 50.
The table is arrested at the termination of each lateral traverse by means of a
disc 60, keyed on the shaft 43, and formed with opposite notches 61, into which a
stopping lever 62, is borne by a spring 63. When the table is next required to bo
moved an extension 64, of the lever 62, is lifted by a projection 65, cast on the
segmentally toothed wheel 41, and allows the wheel 42, to be turned until the lever 62,
enters the next notch in the disc 60.
