Office of the Coinmissioners of Patents on the 20th October 1882.
CARL FRIEDERICH MÜLLER, of Magdeburg in the German Empire, Engineer,
"IMPROVEMENTS IN APPARATUS FOR THE MANUFACTURE OF CONFECTIONERY"
My invention has for its object to manufacture confectionery, which has
hitherto been produced by hand in special moulds, by means of machinery. It
consists first in the application of form plates provided with openings corresponding
in shape and size with the product to be made, and through which is pressed the
mass contained in the receptacle placed over the said form, so as to fall upon a
baking tray supported by a platform placed under the form plate.
Also in coupling the vertical rod which guides the moveable upper press block
or plate with the latter by means of a horizontal shaft carrying at one extremity
a pinion gearing into the rack of the press block, and at the other extremity with
a friction coupling consisting of a disc and two frictional pawls, one of which is
actuated by the mechanism, while the other is pressed against the disc by a
weight.
Also in moving the press block or upper platform by means of a cam which
imparts a vertical motion to the said guide rod and thereby to the press block.
Also in the successive re-adjustment of the press block or upper platform by
means of the cam already mentioned, the spiral-shaped curve of which moves
downward a bellcrank lever, connected with the above-mentioned friction-disc by
means of a vertical rod and a friction pawl, whereby the horizontal shaft with its
pinion is turned.
Also in moving the lower platform or table alternately up and down while at
work, by means of a cam set in motion by means of a worm and worm wheel,
the shape of the said cam depending on the shape of the product to be
manufactured

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Carl Friederich Müller in the Great Seal Patent Office on the
19th April 1883.
CARL FRIEDERICH MULLER, of Magdeburg in the German Empire, Engineer,
IMPROVEMENTS IN APPARATUS FOR THE MANUFACTURE OF CONFECTIONERY,"
This invention has for its object to manufacture confectionery, which has
hitherto been produced by hand in special moulds, by means of machinery. In
describing my invention reference will be had to the accompanying drawing
representing a machine which is composed substantially of the following parts:
A fraine B supports the receptacle E provided in its interior with a rim adapted
to receive one of the exchangable form-plates F The form-plates F are per-
forated with openings corresponding in sliape and size with the product ((sweets)
to be inade. Under the form-plate. F is situated a platform C receiving the baking
tray D; the platform C is mounted on a spindle C¹, by means of which it may
be moved up and down. A pressblock O actuated by the rack xpresses the mass
contained in the receptacle E through the openings in the plates F, from where
it is received by the baking tray. The press block G is moved up and down by
means of an arm El connected with a vertical rod D guided in a suitable guide
situated on the side of the frame. To cause the press block G to automatically
adjust itself according to the sinking of the mass in the receptacle, the said press
Above the arm E¹,
block G is connected with the rod D' in the following manner.
and parallel with the same, is placed in suitable bearings, the shaft W carrying at
one extremity a pinion gearing into the rack of the press block G. At the other
extremity of the shaft is placed a friction coupling consisting of the disc V and
the two friction pawls T and Y. The pawl Y is provided with a weight y¹ which
allows the disc to revolve in one direction only. The pawl T is mounted on an
arm A. If the arm A' is caused to oscillate by the rod S, the pawl T. causes the
disc V to revolve, whereby the shaft W is turned, which causes the pressblock G
to be lowered. The machine works in the following manner:
If the flywheel shaft H is turned, the toothed wheels L and K, which gear into
each other, are set in motion by the worm J, and thereby also the cams M and N,
which are connected with the said tooth wheels. The cam M operates in two
ways; On the one hand, the rod S is moved downward by the plane spiral-
shaped curve mand by means of the cranks Q and R; on the other, hand tho
rod D is slowly pressed downward by the vertical curve m and the pin d
provided with a friction roller, the upward or return motion of the rod D' being
effected by a spring F¹. As soon as the mass has been pressed through the
openings of the form plate F by the downward motion of the press block G, the
press block G moves again upwards, while the baking tray placed on the platform,
which had been pushed upward by the vertical cam N, is rapidly lowered by the
spring O, whereby the confectionery is separated from the form-plate, and falls on
the baking tray, which is then removed sideways and replaced by, an empty tray.
The different stages in the working of the machine are therefore the following:
The platform provided with an empty baking tray rises till it reaches the form
plate F, and then stops: The press block. G then presses the mass through the
form plate F, so as to reach the baking, tray D situated on the platform.
According to the shape to be given to the product, the said baking tray is moved
up and down several times by means of the cam N, during which operation the
press block G. continues to press on the mass. After this has been carried out, the
press block Grapidly separates from the mass, and the platform descends. During

page_text: the detaching of the mass the friction coupling is in action, so as to readjust the
press block according to the quantity of the mass which had been used.
During the replacing of the full baking tray by an empty one, the press block
works without. effect. The rod S is attached to a slide, which may be adjusted
on the crank R, whereby the size of the confectionery to be produced can be
determined.
In machines for the manufacture of confectionery:
1. The application of form-plates F, provided like sieves with openings, the size
and shape of which varies according to the product to be made, and through which
the mass contained in a superposed receptacle is pressed, so as to fall upon a baking
tray placed on a platform situated under the form plate.
2. Connecting the guide-rod D¹ with the pressblock G by means of a shaft W,
provided on one side with a pinion gearing into the rack of the press block, and
on the other side with a friction-coupling V consisting of the discv and the friction
pawls T and Y.
3. Producing the motion of the pressblock G by the cam M adapted to cause a
vertical motion of the guide rod D', and thereby of the press block G.
4. The successive adjustment of the press block G by means of a cam M, the
plane spiral curve of which causes the cranks R and Q mounted on the shaft P to
move downward, which motion is transmitted on the friction disc V by the rod S
and pawl T, the disc V being adapted to adjust the press block G by means of
the pinion x mounted on the shaft W.
5. Causing a successive up and down motion of the platform during the period
of work by means of the cam N, set in motion by the worm J and the curve of
which depends on the shape of the article to be produced.
In Witness whereof I, the said Carl Friederich Müller, have hereunto set my
hand and seal this twelfth day of April A.D. 1883.
