Description
75~7 This invention relates to a household appliance for the production of food pastas.
Modern lines of small electrical appliances for family use have the primary purpose of automating the prolonged, laborious operationsthat arise again and again in preparing foodsat home, which, besides constituting undoubted savings.permit greater variety.
- A household appliance must be of limited size and weight, and must be very functional with accessories that ; 10 fit simply and safely, ~nd must not require exacting main-tenance, which is to say it must have simple, well-pro-tected driving parts and must be completely safe to employ even in inexpert hands.
Generally speaking, the present invention provides a household machine for the production of food pastas comprising sub-stantially a housing of compact form - preferably made of moulded plastic material - and including a comparatively .
,, --1--'; , ~ ' .
~a~
.' ' ~
75i~i7 small mixing vat of a size suitable for normal family use, preferably placed horizontally and being of rounded form, preferably semi-cylindrical or U-shaped cross-section; a kneading part comprising a horizontal arm carrying fins of simple form and of limited surface area - preferably simple rods disposed radially - so as to keep the power drawn by the motor within very low limits compatible with a household application; an electrlc motor and reduction gear assembly to drive the kneader; means to permit the easy assembly of accessories, of conventional type, for the production of pasta forms and for cutting them into the desired sizes.
More particularly, the present invention provides a household appliance for producing`farinaceous products, comprising: a housing having an end wall provided with a seat aperture; a mixing vessel in said housing centered on an axis in line with said seat; bearing means in said seat aperture centered on said axis; agitating means in said vessel for beating a mass of dough, said agitating means including a shaft in line with said axis and a set of radial ; mixing and kneading elements secured to said shaft, a free end of said shaft being rotatably journaled in said bearing means; drive means in said housing positively coupled with an opposite end of said shaft, the latter being dis-engageable from said drive means and axially withdrawable from said housing through said seat aperture; and removable cover means on said housing giving access to the interlor of said vessel.
Preferably, the vessel i5 generally semicylindrical or of U-shaped cross-section, the axiq of which is horizontal.
; The reduction gear assembly is made up preferably of gears of plastic, nylon or the like, with self-lubricating characteristics, among other reasons in order to maintain complete electrical insulation of the motor from the mixing vat.

The mixing vat, in addition, is closed at the top by a cover associated with a safety device, comprising a microswitch or the like, which shuts off the motor automatically whenever the cover is raised and the vat it-self is exposed. This safety devic~ is particularly necessary owing to the particular type of kneading operation carried out, which may require the successive addition of ingredients in the course of mixing.
~2a-... .
~`.' ' .
~75G7 Current is fed to the m~tor through a timing device Or known type which makes it possible to program and control the mixing times. When the mixing is finished, it is possi-ble to take out the kneading arm, which thus acts also as a support for the next operation, rolling of the dough, simply by removing a plug made of plastic, nylon or similar material, with self-lubricating characteristics, and which constitutes one o~ the bearings of said arm.
In place of said plug, it is a simple matter to instal~and to lock in with a safety screw, accessories which are in themselves known, for the production of pasta forms of the thickness desired and for the cutting of said forms for the production of lasagna, noodles, etc.
The operation of these accessories is made possible by inserting a power-transmission shaft from the reducing-gear assembly to the dough.cutting accessory in place of the kneader arm; the ends of this shaft are suitably shaped in order to permit installation in the output of the redu-cing gear and on the shaft of the dough-drawing or dough-cutting accessory.
The substitution of the kneader arm by a trans-mission shaft is provided for not only to permit utiliza-tion of the arm as a support for the dough, but also for safety reasons, so as to prevent accidents from happening in case of failure of the safety switch when the cover is opened with the motor switched on.
,~ ' - -- _ .:
1~75~7 According to a possible variant, the pasta-drawing and pasta-cutting accessories can be installed directly on the reducing gear assembly on the side opposite the mixing vat without requiring the interposition of the transmission shaft.
According to another variant, a special screw conveyer is installed beneath the mixing vat. A special slide permits the dough to pass directly into the casing of the screw, which, when made to turn by the motor, pushes the dough towards a die. This die can be of various sizes, depending on the desired thickness of the mixture.
These and other characteristics and advantages of the invention are brought out by the detailed description which follows, by way of non-limitative example, of a relatively small kneader for household use, illustrated in the accompanying set of drawings, where:-~ .
Figure 1 is a plan section of a machine for the household production of food pastas according to the inv~ntion;
~'! Figure 2 is a cross-section of the machine of Figure l;
Figure 3 is a frontal section of the machine of Figure l;

According to a preferred embodiment of the invention, a portable housing 1 of compact form, preferably made of moulded plastic, and provided with suction-cup feet 2, has a mixing vat 3 placed horizontally with sub-stantially semi-cylindrical or U-shaped cross-section, accessible from above through a hinged lid 4; in space 5, bounded by housing 1 and vat 3, are housed electromotor 6 and speed reducing transmission 7, installed in suitable brackets 8 on the inside walls of housing 1, preferably with the interposition of vi-bration damping and sound-deadening supports 9.
Speed reducing transmission 7, which is of compact form, comprises gears of plastic, nylon or the like and is enclosed in a box 10, preferably of moulded plastic material.
A timing switch, not illustrated, controls motor 6, and a safety switch device II placed in space 5 above speed reducing transmission 7, is connected to the latch of lid 4.
The kneading arm, indicated generically by 12, comprises a revolving shaft 13 which can be secured by bayonette engagement means to the output of speed reducing transmission 7 and carries fins 14 which are of minimum surface area ànd preferably cylindrical, situated radially in staggered arrangement along shaft 13; the opposite end of shaft 13 is supported in a plug 15, the removal of which permits the removal of arm 12. Plug 15 is suitably shaped and is made of material with self-lubricating properties, and is assembled from outside in a hole 16 provlded in housing 1, and can be locked in by tightening screw 17. The pasta-drawing or pasta-cutting assembly, of conventional design, is indicated generically by 18 in Figure 3, and is assembled, after removing plug 15, in hole 16, and is again locked in by tightening screw 17. Mechanical connection between pasta-drawing assembly 18 and speed reducing transmission 7 is secured by the interposition of a shaft 1~, with duplicate bayonette engagement means.

below mixing vat 3 a cylindrical housing 20 is provided within which a screw conveyor 21 turns. Power transmission from speed reducing transmission 7 to said screw conveyor 21 is preferably provided by a chain 22. A slide 23 situated over an opening 24 connecting mixing vat 3 with space 20 controls the passage of the mixture. At the output of screw conveyor 21 a drawing die 25 is immovably secured and is exchangeable for other dies of different shape and size.
