Definitions

• the invention concerns coffee-makers particularly those used in the home.
• Water is heated inside the water-tight base and, on reach ⁇ ing the right pressure, rises into a filter, mixes with the ground ' , coffee, passes up through a column and emerges through holes in the top, then depositing in the dispensing section situated above the base. From there it is poured out into cups.
• Subject of the invention is a portable coffee-maker com- prising a dispenser communica ing with the water-heating base through a perforated column.
• the dispensing part there is a central body and a number of nozzles formed by substantially horizontal ra ⁇ dial arms through which passes an axial hole.
• the central body of the dispenser part is preferably spherical .
• the nozzles consist of bars each having an axial hole; said bars branch out spokewise from a central body at a slightly downward inclination and also taper slightly towards a spherical head at the end. On reaching said sphe ⁇ rical head, the bars, each with an axial hole, form a mouth bent at a sharply downward angle.
• the body of the dispenser there is an axial cavity shaped like a truncated cone with the larger base below, matching at the top with- the dispensing column also trun ⁇ cated-cone shaped at the summit .
• a threaded pin at the top permits a knob to be screwed on Pressure on the dispensing column is made by screwing the knob down until it locks on the column.
• the holes in one set are the same in number as the noz ⁇ zles and are arranged at an equal angular distance in such a way as to connect the column with all the nozzles.
• the holes in the second set are intermediate with the first ones and are fewer in number.
• the dispenser permits distribution through all the nozzles while, if rotated over the angular distance between the two sets of holes, coffee is dispensed only through the nozzles that coin- cide with the holes in the second set.
• the number of holes in the second set is half the number in the first set.
• an aligner spot At the top of the column is an aligner spot and two such spots are placed on the lower part of the dispenser. Coincidence of the first aligner spot on the dispenser with that on the column corresponds to alignment of the first set of transversal holes in the cone-shaped head with the nozzles. Coincidence of the second aligner spot on the dispenser with that on the column corresponds to alignment of the second set of transversal holes in the cone-shaped head of the column with the nozzles.
• a regula ⁇ ting device consisting of a pin that projects from the lower part of the dispenser's central body, parallel to its axis, and of a pair of holes at the top of the column, also parallel to its axis.
• Angular distance between said pair of holes is equal to half that between the nozzles, while their distance from the axis of the dispenser is substantially equal to that of the pin.
• Fig.1 Side view of the portable coffee-maker with its dis ⁇ an comprising several nozzles placed at the top of a column .
• Fig.2 Cross section of said column seen from below.
• Fig.3 An axial section of the dispenser.
• the coffee-maker 10 is formed of a spherical water-heater base 11, of aluminium or cast steel, through which, towards the top, an imaginary cut is made on a horizontal geometrical plane to form an upper mouth 12 and a hed 13 taking the shape of a hollow segment of a sphere.
• This latter has a flat edge 15 threaded Internally to connect to the external thread on the neck of the water heater 11.
• the circular tray 50 on which the coffee cups 51 stand can be placed between the flat edge 14 of the mouth of the water heater 11 and the flat edge 15 of the head 13.
• a dispensing column 20 with a tapering base 21 and a top 22 tapering in the opposite direction, said column having an axial distribution hole 25 communica ⁇ ting with the inside of the head 13.
• a truncated-cone shaped head 23 At the top 22 of the column 20 is a truncated-cone shaped head 23, the smaller base being uppermost, from which a threaded pin 24 projects.
• Said truncated-cone shaped head 23 supports a dispenser 30 comprising a ' spherical body 31 and a truncated-cone shaped chamber 32 to match up with said head 23.
• a dispenser 30 comprising a ' spherical body 31 and a truncated-cone shaped chamber 32 to match up with said head 23.
• a dispenser 30 comprising a ' spherical body 31 and a truncated-cone shaped chamber 32 to match up with said head 23.
• radial seats 33 In the spherical body 31 there are also radial seats 33, at an equal angular distance, with a slightly downward inclination, for the nozzles 40 fitted into said seats 33.
• the body 41 of said nozzles 40 tapers slightly and has a spherical head 42 at the end; an axial hole passes along said nozzles and, on reaching the head 42, takes the form of a mouth 44 turned sharply downwards.
• a first set of six transversal holes placed at an equal angular distance, and when the aligner spot 16, marked on the top of the column 20, coincides with the aligner spot 17 on the lower part of the spherical body 31, these holes will be in line with the holes 43 in the nozzles 40 which are thereby .con ⁇ nected to the axial hole 25 in the column 20.
• Between said holes 35 is a second set of three holes of substantially the same size and in the same positions but half as many as the first set, also placed at an equal angular distance. For the sake of simplicity the figures do not show this second set of holes.
• the dispenser On turning the dispenser for approximately 30° round the axis of the column 20 until it coincides with another aligner spot 18 (in the figure this is indicated by the number 3) placed at an angular distance of 30° with the already mentioned aligner spot 17 and with aligner spot 16 on the column, the above three holes of the second set will be in line with the holes passing through three nozzles. The other three intermediate nozzles will not then commu- nicate with the axial hole in the column 20. It follows that by moving the dispenser to one or another of said radial orientations, the coffee in the dispenser can be run into six cups or into three cups. The dispenser is fixed in the one position or in the other by screwing the knob 26, with its threaded head 27, on the pin 24 in the column 20.-
• the coffee-maker can be built in sizes for respectively 2, 4, 6 or 12 cups. It is clear that the number of holes in the two sets,passing through the chamber in the dispenser's spherical body, hich connect the nozzles with the axial hole in the column, will vary as shown below; the first set is here indicated by the letter (f) and the second set by the. letter (s).
• 2-cup coffee-maker 2 holes in set (f), 1 hole in set (s) 4-cup coffee-maker: 4 holes in set (f), 2 holes in set (s) 6-cup coffee-maker: 6 holes in set (f), 3 holes in set (s) 12-cup coffee-maker: 12 holes in set (f), 6 holes in set (s)
• the water in the base 11 can be heated either on an elec- trie hotplate or on a gas burner.
