PROVISIONAL SPECIFICATION.
Improved Means for Ornamenting Pottery Ware.
We, HENRY LEWIS DOULTON and WILTON PARKER RIX both of the
Lambeth Pottery, Lambeth in the County of Surrey, Potters, do hereby declare
the nature of this invention to be as follows:-
11
The object of this invention is to improve the oronmentation of pottery ware as
it is being turned in a lathe after being dried and before firing. To effect this we
employ a cutting tool formed of a disc having teeth of any desired pattorn
projecting from its circumference and carried by a central axis in a handle or
holder which can be traversed to and fro in a direction parallel with the longitudinal
axis around which the work is being rotated. In this way when the tool is held in
a plane parallel or approximately so with this longitudinal axis and the edge of the
tool is made to bear against the work it can be made to roll along the work at the
same time that tho work is revolved.
The teeth may be formed with cutting or with rubbing or indeuting edges as
desired they may also be placed either regularly or irregularly around the
circumference of the tool. In place also of the teeth being made to project from
the edge of a disc they might project from the circumforence of a cylinder or
sphere.
In place of the tool being made simply to roll along the work it may be revolved
automatically on its vertical axis at any speed desired relatively to the speed of its
movement end wise along the work. It may also be revolved either continuously
or with a step by step movement as desired.
By employing a cutting tool such as above described capable of being moved to
and fro horizontally and turned around a vertical axis at the same time that the
work is revolved around a horizontal axis a great variety of ornamental patterns
may be produced on the surface of pottery ware.
Dated this 31st day of January 1893.

COMPLETE SPECIFICATION.
Improved Means for Ornamenting Pottery Ware.
We, HENRY LEWIS DOULTON, and WILTON PARKER RIX, both of the
Lambeth Pottery, Lambeth, in the County of Surrey, Potters, 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 :-
The object of this invention is to improve the ornamentation of pottery ware as
it is being turned in a lathe after being dried and before firing. To effect this we
employ a cutting tool formed of a disc having teeth of any desired pattern
projecting from its circumference and carried by a central axis in a handle or
holder which can be traversed to and fro in a direction parallel with the longitudinal
axis around which the work is being rotated. In this way when the tool is held in
a plane parallel or approximately so with this longitudinal axis and the edge of the
tool is made to bear against the work it can be made to roll along the work at the
same time that the work is revolved.
The teeth may be formed with cutting or with rubbing or indenting edges as
desired they may also be placed either regularly or irregularly around the
circumference of the tool. In place also of the teeth being made to project from

page_text: the edge of a disc they might project from the circumference of a cylinder or
sphere.
In place of the tool being made simply to roll along the work it may be revolved
automatically on its axis at any speed desired relatively to the speed of its
movement end wise along the work. It may also be revolved either continuously
or with a step by step movement as desired.
By employing a tool such as above described capable of being moved to and fro
horizontally and turned around an axis at the same time that the work is revolved
a great variety of ornamental patterns may be produced on the surface of pottery
ware.
The drawings annexed illustrate the way in which we ornament pottery ware.
Figure 1 is a perspective view and shows a vase a, partially or wholly dried but
unburnt, and mounted upon the mandril 6 of a lathe.. The madril is driven in the
usual manner by a cone pulley upon it around which an endless cord passes. is a
rest bar, it has a screw thread cut upon it and is mounted on standards d d. The
rest bar is rotated, being driven from the mandril of the lathe or otherwise at any
desired relative speed. e is the tool, it is held in the hand of the workman, whilst
it is also supported by the rest bar.
Figure 2 shows separately one of the tools which we employ, it consists of a steel
wheel with blunted spur like teeth upon its periphery; it is mounted to turn freely
upon an axis which is carried in a fork fixed into a handle.
The workman holding the tool by its handle and resting upon the bar c brings
the wliecl into contact with the work.
The screw rest bar causes the tool to progress along the vase in a direction from
top to bottom or parallel to the axis of rotation and the wheel rolling along the
vase its teeth come to act in succession, each in turn operating to remove small
fragments of clay from the surface and in this way the ornamentation of the
surface is produced. A somewhat different effect may be produced by causing the
Inthe to turn in the opposite direction or away from the tool, which is then so
held that it meets the work more nearly tangentially; the teeth then operate to
smooth and burnish and slightly indent the surface without removing any of the
material.
In place of employing a screw rest har e a smooth stationary bar may be
employed and the workman by his hand will unaided give the longitudinal traverse
to the tool at the requisite speed.
Figures 3, 4 and 5 show patterns which have been produced in the manner
described and with the tool shown by Figure 2.
The pattern in Figure 3 is produced as follows:--
The wheel is made to travel while beld horizontally.
The pattern Figure 4 is produced in the same way as Figure 3 but at two
operations; the pattern first obtained being crossed and partially obliterated by a
similar pattern worked in the opposite direction.
To obtain the pattern represented by Figure 5 the tool is employed as
follows:-
"
The wheel is held at an angle of 60 degrees to the horizontal lathe rest and
travels at the same rate as used for No. 3.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
Pottery ware ornamented substantially as described by rotating it and operating
on its face with a toothed wheel caused to roll along the work and travel in a
direction parallel to the axis of rotation.
