IMPROVEMENTS IN MACHINERY FOR MAKING POTTERY WARE
Year: 1887

page_text: WILLIAM HENRY HALES, Ironfounder, Cobridge, Stoke on Trent, Staffordshire do
hereby declare the nature of my invention for IMPROVEMENTS IN MACHINERY FOR
MAKING POTTERY WARE to be as follows :-
My invention has for its object an improved machine for batting potters' clay.
The general method of making articles of pottery ware, is to take a ball of clay,
spread it out to an even thickness and place it over the mould the clay when spread
out being called a "bat."
For the purpose of my invention I use a suitably constructed frame wherein
I provide the necessary details required for supporting the following apparatus :-an
arm or lever provided with a profile or tool at one end, and a balance weight and
projecting piece at the other, and underneath one end of said arm or lever I arrange a
spindle upon which are keyed or otherwise attached to it, a worm wheel in gear with
worm, a cam, brake wheel, and an adjustable arm or lever provision being also
made for worm spindle, brake spring, and strap.
The mode of operating is as follows:-A ball of clay is placed upon a revolving
"head"underneath that end of the before named lever, carrying the profile or tool,
the operator then starts the machine by causing the driving band or rope to come in
contact with a pulley upon worm spindle, and so revolving the worm wheel and
spindle supporting it. The cam in revolving round with the spindle first comes in
contact with the projecting piece on the before named arm or lever, and, forcing it
upwards, consequently depresses the other end, which, provided with a profile or tool
as before mentioned, presses upon the clay and spreads it out. The cam still revolving
releases the arm or lever at a certain point, when said lever is then brought back by

page_text: the balance weight. The cam having released the arm or lever comes 'in contact with,
and presses, the spring which tightens the strap upon the brake pulley. At the time
when the brake is commencing to operate, the aforesaid adjustable arm or lever has
come in contact with a vertical rod which releases the driving band, so that the
brake only takes up the momentum of the machine.
I may here mention that it is not imperative to use the brake wheel described, as
the spring may act directly on the cam and thus retard it.

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
My invention has for its object an improved machine for batting potters clay.
The general method of making articles of pottery ware, is to take a ball of clay,
spread it out to an even thickness either by hand or machinery, and place it over the
mould the clay when spread out being called a "bat."
The accompanying drawings clearly illustrate my invention, the same letters
referring to the corresponding parts in each figure.
For the purpose of my invention I use a suitably constructed frame A, wherein
I provide the necessary details required for supporting the following apparatus :-an
arm or lever B provided with a profile or tool at one end, and a balance weight D
and projecting piece at the other end. Underneath one end of said arm or lever B,
I arrange a spindle upon which I key or otherwise attach to it, toothed wheel F in
gear with tangent screw G, cam H, break wheel I and adjustable arm or lever J,
provision also being made for attaching break spring K and strap L. My invention
is operated in the following manner :-a ball of clay is placed upon a jigger head
underneath that end of the before named lever B carrying profile or tool C, the
operator then starts the machine by causing the driving rope or band to come in
contact with a pulley attached to jigger spindle, and from thence the motion is
transmitted to pulley M, which, by means of tangent screw G and wheel F, revolves
spindle N and the apparatus attached to it. The cam H in revolving round with
spindle N first comes in contact with projecting piece E attached to arm or lever B and
forces it upwards, consequently depressing the other end provided with profile or tool C,
and which pressing upon the clay on jigger head whilst revolving, spreads it out,
thereby forming a "bat." The cam H still revolving, releases lever B at a certain
point, when said lever is then brought back by balance weight D. The cam having
released lever B, next comes in contact with and presses spring K, which tightens
strap upon
wheel I and stop machine. At the same time the break is commencing
to operate, the before named adjustable arın or lever J will have come in contact with
vertical rod 0, which releases the driving rope or band, so that the break only takes
up the momentum of the machine.

page_text: I may here mention that it is not imperative to use the before mentioned break
wheel I, as the spring alone may act upon the cam and thus stop the machine.
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 :-
:-
A machine constructed and operated as herein described and illustrated by
accompanying drawings, for batting potters clay.
