CLAY BATS FOR POTTERS USE
Year: 1885

page_text: WILLIAM EDWARD MADDOCK Lime Cottage Wolstanton Stoke-on-Trent Engineer
& Potters Manager do hereby declare the nature of my invention for MAKING CLAY
BATS FOR POTTERS USE to be as follows:-
Improvements in machinery for making clay Bats for potters use which may be
driven by hand, steam or other power, said improvements consist in the mechanical
arrangement and which I describe as follows: To an ordinary Jolly lever I attach
a vertical connecting rod at a suitable distance from the fulcrum, this rod passes
through the bench, at its lower end is a slot also of suitable length through which
passes a weighted lever working on a joint pin at the other extreme end; another
vertical connecting rod jointed at one end to the weighted lever also passes through
the bench the upper end being attached by a suitable pin to the batting out lever
and at a suitable distance from the fulcrum the balance weight being on the Jolly
lever only: My invention also consists of the application of a sliding tool holder
either for Jolly or Batting tool. This improvement consists of a guide plate
fastened to an ordinary Jolly lever by a bolt & nut and having a sliding tool
holder raised or lowered by a vertical adjusting screw. The improvement claimed
is the adjusting arrangement it being simply neccessary to raise or lower by this
means for any thickness of Bat required.

W. E. MADDOCK Lime Cottage Wolstanton Staffordshire Engineer and Potters
Manager I do hereby declare the nature of my invention for IMPROVEMENTS IN
MACHINERY FOR MAKING CLAY BATS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statenient-
The improvements consist of the application of a dead weight for the purpose of
squeezing out the clay bats instead of by the use of cams or excentrics, and consists
in the use of a lever and connecting rods by means of which the action of pulling
down the jolly or working lever also pulls down the batting lever to the point
when the tool touches the ball of clay, and I so arrange the apparatus that at this
point, the jolly lever and batting lever are independant of each other, the dead
weight then acting on the batting lever, and gradually squeezes down the ball of
clay until it is a bat of the required thickness, by this arrangment the workman
is enabled to bring down his working lever to the mould in the ordinary way
without loss of time, the clay bat being made in a longer or shorter time as required
by adjusting a movable weight along the connecting rod lever nearer to or farther
from its fulcrum. The second part of my invention is the application of a screw
adjusting toolholder, for the use of working jollies or batting machines, whereby
greater saving of time is obtained in the adjusting of the tool, and greater accuracy
of thickness of bat or other profile used.
Accompanying drawings show the manner in which the foregoing discription is
obtained on reference to Fig. 1 which is an end elevation, A is an ordinary Jolly
lever to which I attach a vertical connecting rod A. A at a suitable distance from
its fulcrum, this connecting rod passes through the bench, and at its lower end is
a slot B of suitable length through which passes a lever C, also shown in Fig. 2
which is a front elevation, and in Fig. 3 which is a plan, this lever has on it an
adjusting weight D, and works on a joint pin E at its other extreme end: another
vertical connecting rod F F attached at its upper end to the batting out lever G,
at such a distance from its fulcrum, that it shall throw up to the same angle as the
jolly lever A, also passes through the bench and its lower end H is attached to
the lever C. by a double jaw joint and pin, the counterbalance weight I to throw
both levers up when not at work is on the jolly lever A only, and P representing
the ball of clay to be run down.
The second part of my invention will be seen on reference to Fig. 4. and 5, which
are respectively a plan and elevation on a larger scale of the screw adjusting
slide M Figures 1: 2: 3: J represents the slide plate to the lower end of which
is attached the tool K, and which is raised or lowered according to the thickness
of bat or article required, by a vertical adjusting screw L, the guide M being
attached to an ordinary jolly lever A. or G, by a single bolt and nut O see Fig. 4
it being simply necessary to raise or lower by means of the screw for any thickness
of bat or other article required.

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 application of the dead weight principal to the squeezing out of day
bats.
Second the method of obtaining this.
Third the application of the screw adjustment to jolly or batting machine tools.
