Improvements in Confectionery Ornamenting Machines.
I, THOMAS ROBERTSON, of 107, Queen Street, East, of the City of Toronto, in the
County of York, in the Province of Ontario, Canada, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements in confectionery ornamenting machines
and the object of the invention is to design a machine whereby chocolates, bon bons
and biscuits and other fancy confectionery may be decorated expeditiously and it
consists essentially of a reservoir to contain the decorating mixture suitably sup-
ported and having flexible tubes leading from metallic tubes extending from the
bottom of the reservoir, such flexible tubes being connected at the bottom to
nipples suitably supported and driven, so as to have any desired motion over the
articles to be decorated, which are preferably fed in under the nipples from which
the decorating mixture is caused to exude, by endless bands supported on a suitable
table, the parts being otherwise constructed and arranged in detail as hereinafter
more particularly explained.
Fig. 1, is a perspective view of the machine complete.
Fig. 2, is a perspective view from the rear of the machine.
Fig. 3, is a vertical section through the machine.
Fig. 4, is an enlarged plan view of the bands showing one form of decorating,
the nipples being shown in dotted lines.
Fig. 5, is a detail of the adjustable crank wheel.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A is the main frame of the machine, which is rectangular in form. Bis the
table, which is provided with side bars 13' 13' and central portion 132 affixed thereto.
The side bars are provided at one end with end journal brackets 6 through which
and the supporting journal brackets C extends the cross shaft b. The opposite
ends of the side bars B₁ have secured to them the depending hangers D having
slots d at the lower end. Through the slots extend the clamping screws d', which
may be loosened or tightened, so as to rigidly hold the table at this end when it
has been adjusted to the desired height.
In order to provide for nicety of adjustment I provide the screw spindle E,
which extends through the end bar of the frame and abuts a depending projec-
tion 2 on the free end of the table B. I provide an adjustment at this end of the
table for the purpose of bringing the table and bands F thereon nearer to or farther
from the nipples G in order to accommodate different thicknesses of confections.
The bands are endless bands and extend over the end grooved pulleys F and F2
suitably journalled in bearings attached to the table. The bands F extend over
the top of the table and in order to place the confections in position I provide the
guides H H located to the outside of each band and provided with slots h and set
screws h¹. By this means I ensure the confections being placed straight upon the
band.

page_text: The nipples G hereinbefore described are located in holes on the T-shaped end i
of the heating tube I, which is provided with an open cage I¹ at the bottom end
and a burner 12 at the lower end of the cage. A T-shaped tubular joint I³ is
provided into which leads a tube I in which the gas is supplied to the burner.
The lower end of the joint I³ is provided with a socket, which is supported on
the top of the set screw 22 extending through the cross bar 15. The heat passing
up through the tube I and out through the open ends of the T-shaped upper end i
serves to keep freely soluble the exuding chocolate, sugar, or other mixture.
J is a reservoir containing the mixture designed to ornament the confection.
The reservoir J is surrounded by a water jacket J¹ in which hot water is held.
The reservoir J is pivotally supported by trunnions 2 in bearing jaws at the top
of the arms J2 which extend through slots 63 in the table and secured on the cross
bars of the main frame.
The reservoir J is provided at the lower end with downwardly extending
tubes leading from the bottom thereof, which tubes are connected to the
nipples G G by the flexible tubes made of rubber or other suitable flexible
material in order to permit of a limited horizontal movement.
In order to impart this horizontal movement, which in the present instance is
in all directions I provide a coupling K, which is connected by a rod k to a crank
wheel L secured on the end of a cross spindle supported in suitable bearings on
the end of the machine, and a rod m to a crank wheel M secured to a longitudinal
shaft M¹ supported in suitable bearings at the rear of the machine.
Both the crank wheels are preferably constructed as shown in Fig. 5, in which
it will be noticed that the eye-shaped ends of the operating rod is connected to
a pin n on the side of the block N, which is supported in a suitable guide-way NI
extending diametrically across the wheel. Set screws N2 are provided which by
being adjusted up or down will impart the desired amount of throw through the
rods to the heating tube I and consequently to the nipples G. The result of this
throw is exhibited in one form of ornamentation 3 shown on the confection 4
shown in Fig. 4. The form of the ornamentation of course greatly depends upon
the rapidity at which the bands cause the confection to move underneath the
nipples G.
It is well known that in chocolate ornamentation the mixture must be kept
warm and for this reason I provide the water jacket hereinbefore described.
I shall now describe the means by which the nipples are given the desired
movement and the speed thereof changed as may be desired. On the shaft M¹ I
provide a cone-pulley M2 and a bevelled pinion M³, which meshes with
the bevelled pinion M on the end of the cross spindle 7. This bevel pinion M³
is made in this instance double the size of the bevelled pinion M4 to impart the
desired ornamentation but these bevelled pinions may be of any desired size in
relation to each other. The cone pulley M³ is connected to the cone pulley O
supported on the spindle o by a belt O¹, which passes through the shifting jaws P
forming part of the bar P attached to the sleeve P¹. The sleeve P¹ is provided
with an arm P2 through the end of which extends a screw spindle P³ provided with
an end turning handle p¹. As the end of the screw spindle P3 rotates freely in
the bearings it will be seen that the adjustment of the belt on the cone pulleys
is easily effected. Such adjustment effectually provides for increasing or decreasing
the rapidity of movement of the nipples G as required by the degree of solubility
of the mixture passing through them.
The endless bands F are driven at the hinged end of the table through the
pulleys secured on the cross shaft b¹. On the outer end of the cross shaft (see
Fig. 2) is secured a worm wheel Q, which meshes with the worm 9 on the end of
the shaft q', which is supported in suitable journals and on which is located the
cone pulley Q¹ The cone pulley Q¹ is connected by a belt Q3 to a cone pulley Q³
on the counter shaft o, which is driven through the medium of the belt of the
pulley 02 and belt 03 from any suitable source of power. The belt Q2 is shifted

page_text: upon the cone pulley Q¹ and Q³ by precisely the same style of mechanism referred
to for shifting the belt O' upon the cone pulleys M² and Ŏ.
By adjusting the belt Q³ upon the cone pulleys Q¹ and Q³ of course the speed
at which the bands upon which the confections are placed, are driven, is also
varied accordingly to the rapidity with which the mixture may be caused to exude
from the nipples G in different classes of ornamentation.
Upon the top of the reservoir I provide a suitable cap R having a safety valve r
and a pressure gauge 1 of any usual construction. The centre of the top of the
cap is connected by the pins R' extending through the boss R³ to the spindle S,
such set screws extending into a groove s in the spindle, thereby permitting of
the free rotation of the spindle S and yet forming a means for lifting the cap.
The spindle S is a screw spindle for the major portion of its length and has
secured to it a hand wheel T. The upper end of the screw spindle S extends
through a cross bar U pivotally swung in the hanging frame U₁, which in itself
has the side bars of frame pivotally connected to lugs u attached to a top support-
ing plate u suitably connected to the ceiling. The frame U. may also be provided
with a suitable counter balancing weight sufficient to counter-balance the weight
of the cap R. Connected to the top of the reservoir is a tube V through which the
pressure is exerted upon the top of the mixture.
By turning the hand wheel T so as to raise the spindle in the cross bar U, the
lid may be raised from the top of the reservoir and swung out into any desired
position, any suitable counter-balancing weight serving to retain it in such
position,
By this arrangement I am enabled to get at the contents of the reservoir or to
fill it as the case may be. It will also be noticed that the reservoir is swung on
trunnions 2 at right angles to the cross bar support for the cap, thus enabling me
to secure an accurate fit of the lid upon the top edge of the reservoir. The lid
would necessarily fit upon the top edge tight and be held thereon by means of the
screw spindle S, the cross bar U and its accompanying parts.
Although I show two nipples G and two bands for conveying the confections or
other articles to be ornamented underneath the nipples Ġ it will of course be
understood that I might use one nipple and one band or more than two nipples
and bands, which would have the desired motion imparted to them.
