page_text: Improvements in Machinery for Making Pottery Ware.
I WILLIAM HENRY HALES of Cobridge Stoke-on-Trent in the County of
Stafford Iron Founder do hereby declare the nature of the said Invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention has for its object improvements in machinery for moulding pottery
ware which enables me to make a plate and bat in the one machine at the same
time together with its easy adoption to a cup saucer or bowl making machine
besides it will make articles much quicker than the hand jollies and steam jiggers
and such articles are much more equal because the pressure is even and the
machinery is easier and more certainly regulated without the use of the workmans
hands.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto two sheets of drawings upon which I have
shown one of my machines adapted for making a bat and a plate at the same time
but which may be adapted by a very little alteration hereafter to be explained to
make similar articles at both sides as for instance two cups or it may be used by
the removal of several parts as a single machine for forming either bats or any
article single and if necessary in conjunction with a hand machine when in its
single state.
Figure 1 is a front elevation of the machine in which the parts both above and
below the bench level are shown.
Figure 2 is a side elevation of the same machine showing the parts as there is
seen both above and below the bench level.
Figure 3 is a plan of the machine in which the parts above the bench only are
shown.
Figure 4 is a sectional plan on line 1 and 2 showing the parts under the bench.
The main or operating shaft A is hung in suitable bearings in the upper part of
the frame work of the machine and at one end it carries the eccentric B and at the
other end the eccentric C each of which has a groove around the outer part of its
face to receive friction rollers or studs for reciprocating the arms or guide rods D
and E in brackets D¹ and E¹ which are bolted to the frame work these guide rods
are attached by two small connecting rods I' and J' to the jolly arms I and J causing
them to rise and fall at each revolution while the shape of the cams C and D cause
them to remain down a sufficient time for the adjustable tools F and G to form
respectively a bat and a plate. The machine is driven by the endless rope S, S
pressing against the two grooved pulley wheels K¹ and L¹ these wheels being
thrown in and out of action by a third grooved pulley wheel R which is connected
by means of the lever Z¹ with the thigh rod Z on pressure of which the machine is
started. The Pulley wheels K¹ and L¹ are fixed to the spindles K and L and these

page_text: spindles give motion to the stand for bat L³ and the mould for the finished plate K²
which are screwed on.
Upon the spindle L is fixed a cone pulley L³ which by the aid of a belt
communicates the motion to the large pulley wheel M¹ which is fixed to the
spindle M, this spindle terminates at the top with the bevelled wheel pinion m²
driving a larger bevel wheel m³ with a spur pinion wheel at the back this drives
the spur wheel H on the shaft and thus gives motion to the jolly arms I and J as
already described. After the bat is finished it is necessary for displacing it to stop
that portion of the machine this is done by the rod O which connects the jolly
arm J by means of the lever O¹ to the short shaft N on the bearings T and T¹ and
on this shaft is the vertical rod U with the grooved pulley wheel V at the top and
the action is as follows:-As the jolly arm J is pressed up it simultaneously
presses down the rod O and by aid of the lever Oi and the shaft N forces the
pulley wheel V against the endless rope S, S thereby taking it off the pulley
wheel L' and at the same time applies the brake which instantly stops the
pulley wheel L' and thereby stopping the large pulley wheel M¹ and consequently
the whole of the machine except the spindle K, which it is not necessary to stop
as the finished plate can be taken off without. On the bat being removed the
workman again starts the machine by pressing the Foot lever W and thus
withdraws the pulley wheel V and removes the brake Q allowing the rope to
again run against and revolve the grooved pulley wheel L' and spindle L which
sets the whole machine in motion again as already shown. In the connecting
rod O is a slot x to allow of pressing the foot lever to remove the pulley wheel K
off the rope without interfering with the position of the rod O-The machine is
entirely stopped by setting free the thigh rod Z thereby releasing the pulley
wheel R from its pressure upon the rope and allowing it to run clear of the
wheels K' and L. The speed of the machine may be somewhat regulated by the
adjustment of the thigh rod Z in the lever Z¹ but for making various sized articles
the proportions of the various pulley wheels to each other would be altered.
In the machine for making similar articles at both sides I remove the pulley
wheel V and the brake Q thus allowing all parts of the machine to run free.
In case of the single bat machine the eccentric B, guide rod D, bracket D¹, jolly
arm I and the portion of the frame connected therewith would be removed and for
other articles the pulley wheel V and brake would also be removed.
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
First. The Improvements in machinery for moulding pottery ware which is
capable of making a bat and plate or other articles at the same time while it is
operated by the attendant without the use of his hands and which is also capable
of being operated as a single machine substantially as and for the purpose herein
set forth.
Second. In machinery for moulding pottery ware the new mode of operating
the brake in combination with the pulley V upon the driving rope substantially as
herein set forth.
