Can be made in any suitable length depending on the type of use for which the installation is intended. Wexixi , for example, it is desirable to create a machine for preparing coffee that is to be able to prepare a hundred cups of coffee between servicing, then results

a cartridge installation length of 7620 mm, on which the cartridges with distances of 76.2 mm between their centers are arranged, the required capacity.

In Fig. 2, a batroneneinbau 13 is in cooperation shown with a partial head 11, this cooperation by a cooperation between the bolts 15 on the dividing head 11 and punched openings 16 in the cartridge installation 13 is maintained. In the representation of the

/ Fig. 2 the dividing head 11 is converted by means of a shaft 17 to · * · run in a clockwise direction, the shaft 17 being mounted in an itagerbock 18. The bearing block 18 is with Bearing sleeves 18a are provided and carried by the frame 10.

The partial head 11 is by a Maltese cross movement by means of a Maltese cross 19, which rotates with of the shaft 17 is arranged, clockwise as shown in Fig. 2, rotated. The Maltese Cross is 19 • driven by a pin 20, which is on a crank 21 is arranged. This crank is driven by the main drive

ο shaft 22, which is supported by bearing sleeves 23 in the bearing block 18 to

co is stored, rotated. The main drive shaft 22 can through ο

^ a motor 24 kept in circulation with a reduction gear _ ». will. As can be seen from FIG. 2, the pin 20 acts to with the rotation of the shaft 22 clockwise according to FIG. 2 one after the other with the six slots 26 of the Maltese cross 19 together and thereby generates the

Shaft 22 one sixth of a turn of the Maltese cross 19. Furthermore, the movement of the Maltese cross provides a movement of the drive shaft 17 in such a way that the shaft 17 over 240 ° the rotation of the shaft 22 stops. As a result, the dividing head 11 takes the main drive with one complete revolution shaft 22 one of the six possible displayed positions during two-thirds of such a revolution of shaft 22 a. During the remaining third of the revolution of the parts 22, the dividing head 11 is gradually changed from one such possible position in the next following one.

The partial head 11 is on its circumference with six adjacent ones provided flat surfaces, each of which provides a location 25 for receiving a G-etränkpatrone. At every point 25 a dome 27 (see Fig. 1) is provided, from which a line 28 connects to the interior of the Part head 11 is provided. Every place. 25 'is also provided with a circular sieve 29, which by means of spring clips 30, which extend into the line 28, in the spherical cap 27 is fastened in its position. The spring clips 30 hold the sieve 29 during the actuation of the beverage maker fixed in the dome 27 and at the same time allow easy removal of the sieve for cleaning.

The individual points 25 of the partial head 11 are successively brought into the extraction position, ie in the position in which the dome 27 is located on the upper part of the ' ^: partial head 11, as shown in FIGS. 1 and 2, and in which the line 28 runs in the vertical direction downwards. If such a point is in the extraction position, is immediately below

the position assumed by the line 28 at a point 25 of the partial head 11 is a funnel line 51 with a funnel section 32, a line 33 which is mounted in a frame 34, and a nozzle section 35 _f which is arranged with reference to the position of a on the frame 10 barrel 36 is arranged in the drain position.

The extraction head 12, which is arranged generally above the partial head 11, is held by an arm 37 P which is pivoted towards the bearing block 18 by means of a bolt 38. The extraction head 12 is mounted by means of a lever C 39 about the pin 38 to rotate. The lever 39 is rotatably attached to the arm 37 at its upper end by means of a bolt 39a and to a yoke 40 at its lower end by means of a pivot pin 39b. At its lower end, the yoke 40 receives a cam roller 41, which is arranged to rotate on the yoke 40 by means of a bolt 42. .

The roller 41 cooperates with a HOckennut 43 together in a cam disk 44, which for rotation with the Hauptan- - drive shaft 22 is arranged. The profile of the slot 43 can be seen from FIG.

When the cam disk 44 performs one revolution, the arm 37 and thus the extraction head 12 move through a cycle that begins with the position in the Pig. 1 a downward movement, a lingering at the lowest end such a movement (as it is shown in FIG. 2) and a retraction movement for returning the extraction head 12 to the position shown in FIG. 1 as well as a Lingering in this withdrawn position includes.

The extraction head 12 has a liquid hood 45, which is rersehen with a seal 46, which is in the form of a Ring with a round or square cross-section can be provided and each with that of the six flat surfaces of the dividing head comes into play that is furthest up and the sieve in one uninterrupted line 29 surrounds. The liquid hood 45 is placed on a sleeve 47 -which is telescopic with one rigid on the arm 37 attached cap 48 cooperates. The telescopic movement of the hood 45 and the sleeve 47 into the cap 48 is opposed by the leather 49 resistance, which is between a shoulder 50 located on the cap 48 and a shoulder 51 located on the sleeve 47 is effective.

The extraction head 12 further comprises a Ventilkör- ^c 'by 52 with a head 53' which cooperates with the end on the cover 45 valve seat 54th The valve body 52 is fastened to the cap 48 via its tappet 55 by means of a screw 56.

41 If the extraction head 12 by means of the camshaft / and

the driver device is moved downwards, move the hood 45 and the valve head 53 as a unit until the seal 46 with the surface of the partial head 11 in contact comes. In this position, the downward movement of the hood 45 ends. However, the downward movement of the cap 48 is stopped continued and with it the downward movement of the valve 52, the spring 49 being compressed accordingly. Such a downward movement of the valve 52 lifts the valve head 53 from the seat 54 and thus allows the extraction

liquid flowing through a conduit 56 into the interior of the Extraction head 12 is inserted, penetration into the hood 45 and through it. The pressure to be applied to the extraction liquid can be applied by a pump 57 will.

The beverage maker according to the invention is' through Line up the end of a cartridge installation 13 over the top a dividing head 11, so that the first cartridge 14 next to the sieve 29 of the point 25 of the dividing head, which in the top position, ready to use in such a way made that the openings 16 of the cartridge installation 13 are penetrated by the bolts 15 of the partial head 11. The beverage maker according to the invention is particularly suitable for automatic operation, i.e. operation with an electrical controller that controls the preparation of a cup of the beverage provides when actuating a single control body. For this purpose, a motor 24 with a known Circuit can be arranged so that when a main switch, push button switch or one is operated Coin switch occurs for a period of time necessary to complete one complete revolution of the main drive shaft 22, whereupon it again out of operation is set.

Such a circuit according to FIG. 1 can be a segment switch 58 and an actuation push button 59. The segment switch 58, which is located within the housing of the Motor 24 can be arranged, is arranged so that the segment contact 58a locked against one revolution and the movable contact 58b is in correspondence

80 9 805/012 9 _ ₉ _

with the main drive shaft 22 rotates. The switch 58 is arranged so that the movable contact 58b / when the starting device is in the rest position according to the Pig. I is located between the ends of the segment contact 58a. If the push-button switch 59 is now actuated immediately, the circuit of the motor 24 is closed and the motor begins to cycle. The motor then continuously receives its excitation through the segment switch 58, although the push-button switch 59 has been switched off. When the movable contact 58b performs a full revolution and again ^{assumes the position shown in the I 1} Ig ₀ 1, the circuit of the motor 24 is interrupted, and the device is again in the in 'the lig. 1 position shown. In this position there is a used cartridge on the uppermost point 25 of the dividing head 11. In this operating condition, the pin 20 is about to penetrate into the slot 26 of the Maltese cross 19, which is in the position indicated by 26a in FIG. 2. In a typical jail the control is arranged so that eight seconds are provided for one complete revolution of the main drive shaft, ie the beverage maker according to the invention is able to fill with beverage in periods of eight seconds.

When the device is in this position, the Circuit for the motor is closed and the shaft 22 begins its counterclockwise rotation, penetrates the pin 20 in the slot 26 and causes the dividing head 11 during the next 120 ° of rotation of the shaft 22, to turn 60 clockwise, ei * the closest

Bringing point 25 into the extraction position and thereby introducing a new cartridge 14 to carry out the extraction. During the first 90 ° of the rotation of the main drive shaft 22 from the starting point described, the squat castor is located 41 on the high section of the hat 43. Compartment about 90 ° of the revolution begins the squat roller 41 »the slot 43 towards the lower position, and consequently the extraction head 12 starts moving towards towards the dividing head.

When the main drive shaft has made a rotation of 120 ° from the starting point and the pin 20 has just reached the position of the Maltese slot 26, which is now in the jig. 2 has left the position 26b shown, the jib reel 41 has progressed well on its way towards the lowest point of its movement, and the extraction head 12 is almost in cooperation with the dividing head 11. With continued rotation of the main drive shaft "22" moves the extraction head 12 terminates further downward, and the hung 46 of the S ¹ IUssigkeitshaube 45 now comes to the highest extraction site around with the surface of the part of the head 11 in cooperation. with this cooperation of the downward movement of fflüssigkeitshaube 45. the downward movement of the cap 48 and of the valve 52 continues so that the valve head 53 is separated from the seat 54, causing the extraction liquid to flow downward under pressure through the upper permeable layer 60 of the cartridge 14, through the beverage base 61 contained in the cartridge, through the lower permeable layer 62 and allowed through the screen 29,

from where the liquid extracted from the Q-drink base material 62 down on the inner surface of the dome 27, through the line 28, into the funnel 32 and through the line and nozzle 35 flows into cup 36.

Meanwhile, the main drive shaft 22 has continued to revolve and by the time the desired amount of liquid has passed through the extraction zone the cam disk 44 has no effect on the liquid hood 45. However, as the extraction head 12 rises, it rises likewise the Y-valve head 53 until it interacts with the seat 54 occurs and shuts off the flow of liquid. Thereupon, with continued upward movement of the extraction head 12, the partial head 11 is lifted from the liquid hood 45 and has at the time when the control circuit the motor 24 "removes the energy shown in the Fig..l" Position taken up again.

The invention can be used for preparing beverages find when there are relatively long intervals between the individual set-up times of the machine - several days - lie. It may therefore be necessary to provide greater protection for the material in the cartridges than is possible through the permeable layers.
