1, WILHELM FRIEDRICH MÜLLER of Berlin in the Kingdom of Prussia and German
Empire 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
In order to ico small pastry or confectionery quickly and in large quantities by
hand I employ in place of the hitherto ordinary squirts (or jets) the hereinafter
described apparatuses which I will now proceed to describe with reference to the
accompanying drawings.
.
IS
A is a hollow frame or body level at the bottom and sloping at the top made from
suitable material which has an opening B in the middle at the top on which the
conical funnel or neck C is suitably fixed. Over the latter the bag D made from any
suitable air tight material is drawn. The bottom or base E of the hollow body
bored or perforated through and on each of these perforations there is a tube F which
tubes F may be arranged either in one row (Figures 1 and 2) or in several rows
(Figures 3. 4 and 5). The shape of the tubes F correspond with that of the per-
forations which may be either round square oval or of any other suitable shape.
The small metal tubes F can be used by themselves or in conjunction with other
cylindrical small metal tubes F1 which are advantageously made without seam and are
soldered or otherwise fixed into or onto the tubes F. The small tubes F¹ must be
made of an equal and regular size throughout and can be filed off in case of one side-
or partial-wearing down.
When the tubes F are arranged in several rows their ends should be of a different
length see Figures 4 and 5 but must be so arranged that the height of the material or
ingredient in chamber A above the outlet of the small tubes is the same in each row,
if however the small tubes F are of equal length then the base and cover of the hollow

page_text: vessel or chamber A are inclined lengthwise towards the side Figure 4; if on the
contrary the base of the hollow vessel A stands at right angles to the sides then the
small tubes are themselves of different lengths see Figure 5.
In order that the material may distribute itself equally the slight elevations of the
side parts of the hollow vessel A and the breadth of the same, stand in a fixed
proportion in single rowed apparatus (Figures 1 and 2) the height is greater than
the breadth of the apparatus. With an apparatus of several rows (Figures 3 to 5)
on the contrary the breadth is greater than the height. The inclination of the outer
edge of the side portion of the apparatus that is to say the proportion of h to h¹ is so
arranged that the material can enter equally into all the openings.
In like manner the width of the side part stands in fixed proportion to the opening B'
of the apparatus.
In order to ensure the filling of all the tubes with the material to be squirted out
they are closed by a row of pins G which are fixed in any suitable manner on a metal
bar H Figure G. These pins G are inserted into the interior of the small tubes F and
conjointly with the metal bar H close the mouths of the tubes.
--
The operation is as follows: -When filling the apparatus the openings of the
tubes Fare stopped by means of the pins G then after fixing the bag D over the
funnel the bag D is filled to about two thirds with the thick fluid mixture or
material and securely fastened at the top by means of a cord or other suitable
fastenings. The thick fluid material then flows into the small tubes F and, after
removing the metal bar H which draws out the pins G by a regular pressure by the
hand which holds the bag the fluid is made to flow out of all the openings at the same
time. The outrunning material can be transferred to paper or on to tin baking trays
or other receptacles.
After the bag is emptied as far as the funnel C and the pressure of the hand against
it occasions no further outflow the bag D is untied to a slight extent and by means of
a fold or mouthpiece formed in the bag a certain amount of air is blown in by tho
mouth or otherwise until the bag D is full then it is again firmly tied up and again
squeezed by the hand until all the material is pressed out of the apparatus.
In order to allow the openings of the tubes F together with F to stand away
somewhat from the base on both ends of the apparatus foot I Figure 3 can be
_ applied which can be screwed or otherwise fixed therein somewhat longer than the
small tubes.
On these feet the apparatus stands while in uso and they protect the tubes F
together with F from wearing out by friction while in use.
The side opening K closed while the apparatus is in use serves for cleaning and
examining the apparatus.
Having now particularly described and ascertained the nature of m said invention
and in what manner the same is to be performed I declare that what I claim is :—
1. An apparatus for icing small confectionery consisting of a hollow body A level
at its base and sloping at the top with side parts whose height and breadth 6 stand in
proportion to one another and to the breadth of the middle part B₁ as described,
the base of the hollow body A being perforated and furnished with one or several
rows of small tubes F of corresponding shape with the perforations also the funnel C
and airtight bag D drawn over the funnel C all arranged to act substantially in the
manner and for the purpose herein before described and represented in the drawings
annexed.
2. The pins G arranged in a row or rows on a metal bar H for closing the openings
of the tubes whilst filling the apparatus substantially in the manner herein before
set forth.
3. The feet I fixed on the ends of the apparatus to raise it from the base or surface
onto which the material is discharged and to protect the tubes from wear substantially
in the manner herain hafora and farth

page_text: 4. The metal tubes F¹ of cylindrical form soldered or otherwise secured into or
onto the tubes F in order to attain one regular size throughout substantially in the
manner herein before set forth.
5. The arrangement of the rows of tubes F F¹ of equal length with the inclination
of the hollow body A substantially in the manner and for the purpose herein before
described and represented in Figure 4 of the drawings horeto annexed.
6. The arrangement of rows of tubes of different length with the level base of the
hollow body A substantially in the manner and for the purpose herein before
described and represented in Figure 5 of the drawings hereto annexed.
