Improvements in and relating to the Process of and Apparatus for
Manufacturing Sweets.
I, PAUL LINDEMANN of 30 Haupstrasse, Leipzig, in the German Empire,
Confectioner, 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 the method and apparatus employed for the manu-
facture of sweets which are coated or covered with chocolate or other substance.
Such sweets up to the present time have usually been formed by dipping each
piece separately into and removing it from the liquid coating or covering substance
and then laying it upon a sheet of paper for the covering to dry or become hard.
This method was exceedingly tedious and wasted a great amount of time.
The object of the present invention is to effect a saving in the time employed
in the manufacture of such sweets, and as a consequence to render their pro-
duction much cheaper. The apparatus by which these ends may be achieved is
illustrated by the accompanying drawings reference to which is hereinafter made.
Figure 1 illustrates in plan the general arrangement of the constituent parts of
the apparatus.
Figure 2 shews a section of the apparatus taken along the line xx Figure 1.
Figure 2 and all the following figures are drawn to a larger scale than is Figure 1.
Figures 3 to 12 illustrate different parts of the apparatus with their modifications
and the devices by which they can be reversed, in different positions.
As illustrated by the drawings the apparatus consists of a rectangular frame a
carrying at opposite ends a series of arms or cranks b pivoted at c as shewn in
Figure 2. Each of these cranks or arms is connected to the one opposite to it by
a series of light wires or rods e (Figures 2, 3, and 7) so that a number of hinged
trays are formed extending across the frame of the machine. The pivots c are
preferably secured in place by small nuts d Figure 3. The hinged trays may
consist of the parallel straight wires e as described, and furnished with distance
pieces for they may be formed of the net work or trellis work illustrated by
Figures 8 to 12 or of equivalent forms. A further modification as illustrated by
Figure 6 consists in substituting the parallel rods e by a single rod e' carrying
transverse pins or rods e².
A rotary motion is imparted to the transverse shelves to provide for the
displacement of the covered sweets. One method of accomplishing this, as shewn
in Figures 2, 4, and 5, is to provide a rod or bar g which is attached to one of the
parallel rods e of each crank b. One of the bars may be employed at each side
of the apparatus and each will be furnished with a handle h. As shewn by
Figure 4 and Figure 5 the bar g limits the movements of the trays to an angle of
180 degrees. In the modification illustrated by Figure 7 the rods 9 is attached to
the shafts c outside the frame a the shafts being suitably cranked. By this arrange-
ment a complete circular motion may be imparted to the trays.
The sweets which are to be coated with chocolate or other substance are laid
in rows upon the lattice or perforated trays. The frame is then lifted by the
handles and is dipped horizontally into a vessel containing the coating or
covering liquid. If the sweets are only required to be coated on their lower
parts they are submerged to the required depth. Should it be necessary to
completely coat or cover the sweets a piece of suitable wire netting or lattice
work is laid over the top of the frame to prevent the sweets floating off the
trays when they are submerged. The frame and the trays and the contained
sweets are then withdrawn from the bath.

page_text: It is now necessary to remove the sweets from the trays, the frame being laid
upon a sheet of paper and the upper netting if used is removed. Rotary motion is
imparted to the trays by the rod g preferably to the extent of 180 degrees, the
former lower faces of the trays being now at the top for the reception of a fresh
lot of sweets. An angle of 45 degrees is however only necessary to effect the
displacement of the covered sweets.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,―
An apparatus for use in coating or covering sweets consisting of a frame
provided with transverse lattice or perforated trays and means for rotating or
partially rotating the trays, constructed and arranged substantially as hereinbefore
described and as illustrated by the accompanying drawings.
Dated this 24th day of March A.D. 1893.
