An Improvement in and applicable to Potters' Jollies.
We, JAMES KENT, Old Foley Pottery, Longton, Stoke-on-Trent, Staffordshire,
Earthenware Manufacturer, and FREDERICK DAVIES, 33, Berdmore Street, Fenton,
Stoke-on-Trent, Staffordshire, Potters' Manager, do hereby declare the nature of
this invention to be as follows:-
This our invention has reference to an improvement in, which is also applic-
able to potters' jollies with which tools are used for turning or shaping the
interior of plastic hollow earthenware vases or similar necked vessels, the objects
of our said invention being to economise labour and time by constructing such
jollies or machines with a detachable and slidable tool-holder for facilitating the
shaping of the interior of such vessels.
In carrying our said invention into practice, instead of fitting or attaching
a slotted or other ordinary tool-holder as is usually done direct to the socket
of such jollies we interpose, fix or fit a suitably shaped cast-iron, malleable iron
or other suitable metallic block having a longitudinal groove of suitable cross-
section formed in its upper surface, in which groove or slot we fit a slidable
cast-iron, a steel or other suitable metallic bar having a toothed-rack with any
suitable number of cast-iron, malleable iron or other suitable transverse teeth
of suitable shape formed thereon, or attached or fixed thereto, at each side of
such rack to the said block we attach the lower end or portion of suitably
shaped cast or rolled metallic plates of suitable thickness and height, between
which plates we pivottally suspend or mount a metallic quadrant of suitable
size so that transverse teeth formed in or on its lower curved or peripheral
edge will gear into the teeth of the said slidable rack-bar, one end of a suitably
shaped metallic or wood and metallic handle of suitable length being attached to,
cast in one with, or forged on or to the upper end of the said toothed quadrant.
We first fit or fix one end of the said metallic block with its slidable rack-
bar and toothed quadrant into the socket-end of the pivotted lever of such jollies,
we then fit or fix the spigot-end of an ordinary tool-holder for such machines
into, a socket formed in the front end of the said slidable rack-bar.
After the front end of the lever of a jolley to which such an appliance, a tool-
holder and tool are fitted has been pulled down to place the profile tool within
the articles in its mould attach to a jigger-head, such tool with its holder can
be readily slid back or pulled forward so as to facilitate the shaping or turning
of the interior of hollow-carthenware vases, flower holders or flower-pots or
similar necked vessels.

We, JAMES KENT, Old Foley Pottery, Longton, Stoke-on-Trent, Staffordshire,
Earthenware Manufacturer, and FREDERICK DAVIES, 33, Berdmore Street, Fenton,
Stoke-on-Trent, Staffordshire, Potters' Manager, 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:—
This our invention has reference to an improvement in, which is also applic-
able to potters jollies with which tools of suitable profile are used for turning
or shaping the interior of hollow plastic earthenware vases or similar necked
vessels, the objects of our said invention being to economise labour and time by
constructing such follies or machines with a detachable and slidable tool-holder
for facilitating the shaping of the interior of such vessels.
In carrying our said invention into practice, instead of fixing or attaching a
slotted or other ordinary tool-holder as is usually done direct to the socket of
such jollies we interpose, fix or fit a suitably shaped cast-iron, malleable iron
or other suitable metallic block having a longitudinal groove of suitable cross-
section, in which groove or slot we fit a slidable cast-iron, a steel or other suitable
metallic bar of suitable length having a toothed rack with any suitable number
of cast-iron, malleable iron or like suitable transverse teeth of suitable shape and
width formed on its upper surface, or attached or fixed thereto, at each side of
such rack to the said block we bolt or attach the lower end or portion of a suitably
shaped cast or rolled metallic plate of suitable thickness and height, between
which plates near to their upper end we pivottally suspend or mount a metallic
quadrant of suitable size so that transverse teeth formed in or on its lower
curved or peripheral edge will gear into the teeth on the upper side or surface
of the said slidable rack-bar, one end of a suitably shaped metallic or wood
and metallic handle of suitable size and length being attached to, cast in one
with, or forged on or to the upper end of the said toothed quadrant.
In order that our said invention may be more readily understood and described
in detail we have hereunto annexed a sheet of drawings on which letters of
reference are marked.

DESCRIPTION OF DRAWINGS.
Figure 1 is a side elevation of our improved tool-holder.
Figure 2 is an end elevation looking in the direction indicated by the arrow,
and
Figure 3 a plan view of Figure 1.
On referring to the drawings hereto annexed we first fix or bolt the pro-
jecting pin a of such appliances into the socket, end of the pivotted lever of
a potters' jolley as usually made and then holt or fix the upper end or stem
of the profile-tool to be used to one side of the slotted portion b bolted to the
inner end of the rack-bar c. After the front end of the lever of the jolley to
which such an appliance has been bolted or fixed has been pulled down by
the left-hand to place the profile-tool within the article in its mould attached to
the upper end of a revolving or revolvable jigger-head, such tool attached to
such holder can be readily slid-back or pulled forward by raising or lowering
the handled which causes the teeth e of the quadrant f to gear into the teeth g
on the upper side of the bar c and slide such bar in its groove or guide, the
metallic handle h bolted to the upper surface of the fore-end of the right-hand
plate being gripped by the right-hand to steady such tool-holder whilst using
or sliding same.

page_text: 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:
The construction of a detachable slidable tool-holder for potters' jollies having
a quadrant pivotted at its upper end between two uprights or standards, the
said quadrant having suitably shaped teeth on its curved portion or periphery
gearing into suitably shaped teetli formed on the upper side or surface of one
end of a slidable metallic bar on a slide or between suitably shaped guides, and
operated by means of the handle attached to or formed on such quadrant as
herein substantially described, set forth and shewn on the drawings hereto
annexed.
