We, JOHN SULLEY, of 10, Catherine Court, Seething Lane, London, Con-
fectioners Trade Valuer, THOMAS COLE and WILLIAM LAWES COLE, both of St.
Ann's Road, Burdett Road, Bow, London, Engineers, do hereby declare the
nature of this invention to be as follows:-
According to the usual method of making hand made articles from chocolate
paste, a marble or stone slab is employed with one or more gas jets under it
to impart heat thereto while the .operatives are turning over and manipulating
the substance into various forms of confectionery. The operatives employ knives
or spatulas with which to turn the mass over to thoroughly agglomerate it, and
in doing so it often happens that the surface of the slab becomes roughened and
sometimes cut through carelessness or other causes, so that the chocolate fills
in the crevices and does not leave the slab freely, it being essential that the sur-
face be kept perfectly smooth and with that object in view, by our invention
we avoid all the foregoing difficulties and inconveniences by making the table of
highly polished steel or an alloy capable of bearing a high polish and a per-
fectly smooth surface not liable to injury as with a marble or stone slab. With
such a metal slab or table, we employ preferably exhaust steam for heating the
under surface, the steam passing through pipes or channels regulated by valves
that the centre part of the table can be heated more than the edges, the steam
flowing through pipes arranged so that the middle portion of the table is the
hottest and the ends or sides of the table comparatively cool, whereby the sub-
stance can be placed on the middle or hotter part and then gradually moved to
a cooler part and at a temperature specially adapted for the operatives to manipu-
late it, the tendency to overheat as at present being avoided.
The metal table as part of our invention may be of a thickness to admit the
steam pipes in hollows, and the thickness of the table may vary in its length,
so that the central thicker part need only be heated, the ends being heated by
conduction therefrom.
For ordinary work the pipes or channels may be arranged spirally or cir-
cuitously on the underside of the table, the steam entering at one end near the
middle and passing from end to end until it has travelled all under the table
when it leaves in a comparatively cool condition, by this means the centre of
the table is kept very hot and the outer circumference practically cool, or the
pipes or channels may be arranged in any other manner to effect, the desired
result.
The series of pipes or channels may be enclosed or shielded on their under

page_text: side such as by asbestos packing or lagging to prevent the heat escaping except
through the top plate.

An Improvement connected with Chocolate and like Confectionery
Makers Tables.
We, JOHN SULLEY, of 10, Catherine Court, Seething Lane, London, Con-
fectioners Trade Valuer, THOMAS COLE and WILLIAM LAWES COLE, both of St.
Ann's Road, Burdett Road, Bow, London, Engineers, 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:
According to the usual method of making hand made articles from chocolate
paste, a marble or stone slab is employed with one or more gas jets, under it
to impart heat thereto while the operatives are turning over and manipulating
the substance into various forms of confectionery. The operatives employ knives
or spatulas with which to turn the mass over to thoroughly agglomerate it, and
in doing so it often happens that the surface of the slab becomes roughened and
sometimes cut through carelessness or other causes, so that the chocolate fills
in the crevices and does not leave the slab freely, it being essential that the sur-
face he kept perfectly smooth and with that object in view, by our invention
we avoid all the foregoing difficulties and inconveniences by making the table of
highly polished steel or an alloy capable of bearing a high polish and a per-
fectly smooth surface not liable to injury as with a marble or stone slab. With
such a metal slab or table, we employ preferably exhaust steam for heating the
under surface, the steam passing through pipes or channels regulated by valves
that the centre part of the table can be heated more than the edges, the steam
flowing through pipes arranged so that the middle portion of the table is the
hottest and the ends or sides of the table comparatively cool, whereby the sub-
stance can be placed on the middle or hotter part and then gradually moved to
a cooler part and at a temperature specially adapted for the operatives to manipu-
late it, the tendency to overheat as at present being avoided.
The metal table as part of our invention may be of a thickness to admit the
steam pipes in hollows, and the thickness of the table may vary in its length,
so that the central thicker part need only be heated, the ends being heated by
conduction therefrom.
For ordinary work, the pipes or channels may be arranged cir-
cuitously on the underside of the table, the steam entering at one end near the
middle and passing from end to end until it has travelled all under the table
when it leaves in a comparatively cool condition, by this means the centre of
the table is kept very hot and the outer circumference practically cool, or the
pipes or channels may be arranged in any other manner to effect the desired
result.
The series of pipes or channels may be enclosed or shielded on their under
side such as by asbestos packing or lagging to prevent the heat escaping except
through the top plate.

page_text: The annexed drawings indicate several ways in which our invention can be
carried into effect.
Figure 1 is a longitudinal section of a table, and Figure 2 an under plan in
which the steam enters by the pipe A arranged under the centre of the table B
and passes on either side by other pipes C and again passed along outside the
pipes A, C. by other pipes 1) to an outlet E.
Figure 3 is a plan of another arrangement of piping in which the steam is
passed through the pipe A and returned by the pipes C to the outlet E at the
same end of the table as the inlet.
Figure 4 is a section of a table 13 in which a single steam pipe A is employed
this being arranged in a channel F under the table and protected by packing and
plate G so as to preserve the heat as much as possible to the centre of the table,
the heat being conveyed to the edges of the table by conduction.
H, is a ledge on which the operator performs part of his work.
Figure 5 is a plan of an arrangement of steam piping whereby the steam is
conveyed along the pipes A and C to the outlet E, the pipe C being arranged
on each side of the pipe A with its outlet at the opposite end to the inlet.
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 improvement connected with chocolate and like confectionery makers
tables consisting in making such tables of steel or an alloy having a highly
polished surface and prviding the under or other part with steam tubes so
arranged that the hottest part is nearest the centre line of the table, as and for
the purpose set forth and substantially in the manner indicated.
