PROVISIONAL SPECIFICATION.
Improved Method of and Apparatus for Boiling Syrup for
Sweetmeats.
I, EDWARD SHAW, of 6, Cornwallis Crescent, Clifton, Bristol, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to boiling sugar, glucose, and other like syrups for use in
the manufacture of sweetmeats.
According to this invention, the sugar, glucose, or other like syrup is forced
under pressure through the space provided between two concentrically disposed
pipes of different diameter, the innermost of which is charged with steain.
Suitable inlets are provided for the steam, and outlets for the escape of water due
to the condensation of the steam.
The syrup, as it passes between the pipes, is cooked to the required degree by
the steam within the inner pipe.
The outer pipe may also be enclosed in a steam space so that the syrup may be
cooked from both sides.
By this process and in cases where the syrup is heated only by the inner steam
pipe, which is made removable, any syrup burnt on the surface of the pipe can be
scraped off after the pipe has been taken out.
Dated this 8th day of November 1895.

Improved Method of and Apparatus for Boiling Syrup for
Sweetmeats.
I, EDWARD SHAW, formerly of 6, Cornwallis Crescent, Clifton, Bristol, and
Dow of 9 Lower Castle Street, Bristol, Engineer, 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 invention relates to boiling sugar, glucose, and other syrups for use in the
manufacture of sweetmeats.
According to this invention, the sugar, glucose, or other syrup is forced under
pressure through the space provided between two concentrically disposed pipes of
different diameter, the innermost of which is charged with steam.
The syrup, as it passes between the pipes, is cooked to the required degree by
the steam within the inner pipe.
The outer pipe may also be enclosed in a steam space so that the syrup may be
cooked from both sides.
Referring to the accompanying sheet of drawings, Fig. 1 shows, in section,
apparatus arranged for boiling syrup in accordance with this invention.
The copper pipe a is passed through the larger pipe b, also of copper, which is
closed at each end by covers 6¹ brazed to, or screwed on, the pipes a and b.

page_text: Steam is charged into the pipe a at one end thereof and issues at the other end.
An outlet a' is provided for drawing off steam condensed in the pipe a.
The syrup
is forced under pressure into the pipe 6 through the inlet 6 and passes out at the
outlet 6. In its travel through the pipe 6 the syrup is cooked by the action of
the steam in the pipe a. By an escape pipe 64 the vapour or steam generated
from the syrup escapes.
The pipe a is removable, and any syrup which may be burnt on to its exterior
may be scraped off after the pipe has been taken out.
The pipe b may be surrounded by a steam jacket so as to enable the syrup to be
cooked from both without and within.
At Fig. 2 is illustrated, at a reduced scale, a multiple arrangement of the
apparatus. In this arrangement the steam admitted at a circulates in the pipe a
and escapes at the opposite end. The steam is discharged at a'. The syrup
forced in at the inlet 6 of the top pipe passes out at the opposite end by the pipe b
into the cooking chamber next below and thence at the opposite end by the pipe b³
to the third cooking chamber whence it is withdrawn at the outlet 6°. The vapour
or steam generated from the syrup passes out at the outlets bª.
The condensed steam from the pipe a is drained off at a*.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the said is to be performed, I declare that what
I claim is
1. Apparatus for boiling or cooking syrup in preparing it for use in the manu-
facture of sweetmeats and for like uses, consisting of a pipe such as a for conveyance
of steam and a pipe of larger diameter such as 6 through which the pipe a is
concentrically passed, the pipe a being furnished with a suitable outlet for the
steam and for water due to condensation of steam, and the pipe b being furnished
with inlets and outlets for the syrup and with outlets for the vapour or steam
generated from the syrup, substantially as hereinabove described and shown in the
accompanying drawings.
2. Apparatus for boiling or cooking syrup in preparing it for use in the manu-
facture of sweetmeats and for like uses, such as set forth in the preceding claim
with the addition of a steam jacket fitted to the cooking chambers b, the said
jacket being fitted with suitable inlets and outlets for the steam.
Dated this 30th day of July 1896.
