According to another emh~1=6~ of the invention, the transfer of the mixture formed within the mixing bowl to the extruder unit is further facilitated, thus providing a further reduction of the absorbed power and a higher rate of production by separating the function of blending of the ingredients from the function of the thrust of the mixture formed towards the extruder unit and through the proper opening.
The improvements of this invention are provided to obtain a compact machine which may be easily assembled and disassembled, to permit the simple and rapid cleaning of said operating elements, and when operating is free from leakage of contents. According to a first characteristic of this invention, the mixing and thrust member of the improved apparatus is provided to reduce the required power and to speed up the work. This member comprises a shaped pinion which can be mounted on the take-off vertical shaft of the motor reducer. The mixing member is provided on its upper portion, with two opposed and staggered inclined radial blades forming the mixing means and, at its lower end, a blade-like member with curved lower surface, rotatably mounted on a pin radially extending from the pinion and biased by a spring to keep its rear profile compressed against the bottom of the mixing bowl. The blade-like member forms the separate thrust means.
On the pinion is also provided an inclined radial member which serves to remove the mixture adhering to the bottom of the bowl.
Other features, which will be described in detail later, are provided to prevent the blade-'ike member jamming, due to the dough penetrating into its shaft of rctation and its spring.
1~134~1 According to a further characteristic of the present invention, the extrusion screw is provided with a further thread on its terminal area adjacent the output screw, shaped to divide and distribute homogeneouslythe dough mixture against the said screw thus reducing the axial thrust on the output screw.
According to the present invention means are provided to permit the simple assembly and disassembly of the operative groups for cleaning, but avoiding any penetration of flour or dough mixture into the space enclosing the motor reducer unit.
In particular the bowl is inserted in a remavable manner into a suitable space of the frame outer body of the machine, and it is supplied, in relation with the passage hole of the reducer shaft, with a protection sleeve vertically extending, and around which is inserted the pinion of the mixing element, said pinion being shaped as a cap to realize a double protection of the shaft and of the motor reducer.
According to another feature, the extrusion unit is formed as a box - in which the extrusion screw rotates - insertable in a removable manner into a suitable seat on the machine body. Other features, which will he further described, are provided to avoid the flour or dough penetration into the space cortaining the motor reducer, where the bowl and the extrusion unit are joined.

Referring to figs. 1 to 8, a machine according to my ' invention is shown. This machine is used for the preparation and for the extrusion of dough in a variety of shapes, for example, pasta. In general the machine comprises a mixing unit 1, an extrusion unit 2 and a motor-reducer 3 with two output shafts, wherein the units 1, 2 and 3 are enclosed within a frame outer unit 4 which is advantageously made in moulded plastic.
The outer body 4 is provided with an open upper space 41 for housing removable the mixing unit 1, a side open space 42 connected through an opening 43 with the said space 41 for housing the removable extrusion unit 2, and finally an inside space 44, which is substantially isolated with respect to the spaces 41 and 42, housing the motor-reducer 3, The vertical take-off shaft 301 of the unit pro~ects vertically and is centered within the space 41, whilst the second take-off shaft 302 is internally hollow and shaped to drive portion 211 of screw 210 i,n shaft 302 is po~itioned facing the space 42.
The mixing unit 1 comprises a bowl 100 with a vertical ~? 'axis and a substantially cylindrical shape, which i5 also advanta-geously made in m~ulded plastic, and connected at the upper portion - to a rim 101 which engages the edge of the space 41.
A cover 103 may be screwed onto the upper flange 102 of the bowl 100. The bottom opening 104 is provided for connection with the extrusion unit 2, and has a portion 105 forming the conveyor member of the installation. Likewise, the bowl walls are provided with relief ribs 106 suitable for promoting the blending of the ingredients by the mixing member. The bottom of the cylindrical bowl, bored for the passage of the shaft 301, is provided with a sleeve 107 acting as a protection, co-operating - as described hereunder - with the cap-like pinion of the mixing member for the purpose of preventing the outflow of flour or dough from the bowl 100 towards the spaces 41 and 44. The mixing unit 1 comprises finally the mixing and thrust member - generally referenced 110 -which can be inserted removably onto the take-off shaft 301 of the motor-reducer. The mixing and thrust member is equipped with separated means for obtaining the blending of the ingredients and for the thrust of the dough formed towards the extrusion unit.
The mixing and thrust member 110 comprises a shaped pinion 111 having two overlapped areas of different diameter: the lower area 111' having a cantre hole 112 of a diameter such as to allow for its insertion around the protection sleeve 107 of the bowl 100, whilst the upper area 111" has a centre hole 113 which is shaped for the insertion and removal of a bayonet type joint - onto the shaft 301. Therefore, the first advantage of the said embodiment is evident, consisting in that it allows complete protection of the motor unit against the probable penetration of flour or of the dough, due to the double protection of the shaft formed by sleeve ~i~13'~
107 and at the cap-like pinion 111.
The thrust means, consisting of a blade-like member 114 with lower surface 114' curved as shown in Fig. 4 and is radially and resiliently mounted on the lower area 111' of the pinion. The thrust means has a se~tion such as to form a side vertical plane.
The pinion 111 is provided with a radial pin 115, the free end of which is internally hollow and threaded. A flat spring 116 bears through a slot 118 of the blade-like member 114.
A through hole 117 and shaped slot 118, in member 114 provides for insertion of the pin 115 and the spring 116, and member 114 is locked by the cap screw 119. The blade-like member 114 is therefore free tc move anguLarly about the said pin 115 but against the action of the said spring 116, which tends to keep rear profile of member ~14 pressed against the bottom of the bowl 100. The particular shaping of the said member 114 and of the means for mounting it on the pinion 111 prevents the penetration of flour or portions of mixture into the through hole 117 and the slot 118, which could otherwise jam the blade-like member 114 itself.
On the lower area 111' of the pinion, diametrically opposite the thrust member 114 - a radial slant memher 120, suitable for removing dough from the bottom of the bowl 100 against it, thus improving the mixing and the thrust operations.
In the upper area 111" of the pinion - with a smaller diameter - two or more slanted mixing blades 130 are provided, operating as known in the art and suitable for obtaining the blending of the said ingredients.
134;~1 The extrusion unit 2 comprises an outer body of cylindrical - shape - generally referenced 200 - within which the screw 210 suitable for transferring and for co~pressing the mixture formed against the outlet plate 220 is forced.
The outer body 200 is advantageously made in.moulded plastics and it has a substantially parallelepiped shape - which can be inserted and withdrawn from the space 42 of the frame body 4 of the machine - and an internal cylindrical cavity 201 open in correspondence with the outlet plate 220 and lockable through a threaded ring nut 221. The opposite end has a hole 202 for the passage of the shaft 211 of the said screw 210, and its joint on the take-off shaft 302 of the motor-redu~er.
The outer upper surface of the said body 200 has a first recess 203 shaped in such a manner as to receive only partially the bottom of the mixing bowl 100, passing through the connection opening 43 of the space 41, and in addition an opening- 204 in correspondence with the opening 104 of the bowl 100, the s~id opening being adjusted by means of the slide member 205 which latter slides within a horizontal slit 206 in the upper wall of the body 200.
With the purpose of facilitating the location of the body . 200 within the space 42, its lower surface has a guide relief member (not shown) co-operating with a transverse recess 207 made. on the lower surface of the spool type body 200, which moreover is locked ~
during the operati.on - by the joint of the shaft 211 of the screw on the take-off shaft 302 of the motor reducer.
Therefore, the joint between the body 200 and the mixing bowl 100 prevents the outflow of the mixture in its passage from the - mixing unit 1 to the extrusion unit 2.

The screw 210 - illustrated in detail in figs. 7 and 8 -has on its terminal area, adjacent the output plate 220, a f~rther thread 212 intermediate respect with the main thread 213; this allows, in addition to a better distribution of the mixture against the plate 220, for a reduction of the axial thrust thus improving the functional characteristics of the screw itself, and in particular reducing the power absorbed.
According to another embodiment of the machine of the present invention, a cover having a feed openina is assembled on the bowl of the mixing unit. The mouth of the opening is formed by vertical walls sticking out of the external surface of the cover, the feed opening communicating with a channel conveyor oriented in the direction of the mixing means rotation, on the bottom of said channel conveyor being present a tooth to break the yolk of the eggs in the feeding.
This further feature of the apparatus according to the present invention is shown in the figures 9 and 10, in which 5 is the removable cover, advantageously in a transparent plastic material to permit the control of the mechanical preparation of the dough. Said cover 5 is provided with a feed opening 6, which mouth is formed by vertical walls sticking out of the external surface of the cover 5, said walls being provided for retaining the ingredients in the feed opening.
~ aid opening 6 is furthermore communicating with a channel conveyor 8 oriented in the direction of rotation of the mixing means (arrow F of Fig. ~). Such arrangement of the channel 8 prevents the ingredients splashing out of the cover.
To break the yolk of the eggs fed into the opening, the : bottom of the cited channel conveyor 8 of the machine according to the present invention is provided with a sharp tooth 9.

Referring to figs. 1 to 8, a machine according to my ' invention is shown. This machine is used for the preparation and for the extrusion of dough in a variety of shapes, for example, pasta. In general the machine comprises a mixing unit 1, an extrusion unit 2 and a motor-reducer 3 with two output shafts, wherein the units 1, 2 and 3 are enclosed within a frame outer unit 4 which is advantageously made in moulded plastic.
The outer body 4 is provided with an open upper space 41 for housing removable the mixing unit 1, a side open space 42 connected through an opening 43 with the said space 41 for housing the removable extrusion unit 2, and finally an inside space 44, which is substantially isolated with respect to the spaces 41 and 42, housing the motor-reducer 3, The vertical take-off shaft 301 of the unit pro~ects vertically and is centered within the space 41, whilst the second take-off shaft 302 is internally hollow and shaped to drive portion 211 of screw 210 i,n shaft 302 is po~itioned facing the space 42.
The mixing unit 1 comprises a bowl 100 with a vertical ~? 'axis and a substantially cylindrical shape, which i5 also advanta-geously made in m~ulded plastic, and connected at the upper portion - to a rim 101 which engages the edge of the space 41.
A cover 103 may be screwed onto the upper flange 102 of the bowl 100. The bottom opening 104 is provided for connection with the extrusion unit 2, and has a portion 105 forming the conveyor member of the installation. Likewise, the bowl walls are provided with relief ribs 106 suitable for promoting the blending of the ingredients by the mixing member. The bottom of the cylindrical bowl, bored for the passage of the shaft 301, is provided with a sleeve 107 acting as a protection, co-operating - as described hereunder - with the cap-like pinion of the mixing member for the purpose of preventing the outflow of flour or dough from the bowl 100 towards the spaces 41 and 44. The mixing unit 1 comprises finally the mixing and thrust member - generally referenced 110 -which can be inserted removably onto the take-off shaft 301 of the motor-reducer. The mixing and thrust member is equipped with separated means for obtaining the blending of the ingredients and for the thrust of the dough formed towards the extrusion unit.
The mixing and thrust member 110 comprises a shaped pinion 111 having two overlapped areas of different diameter: the lower area 111' having a cantre hole 112 of a diameter such as to allow for its insertion around the protection sleeve 107 of the bowl 100, whilst the upper area 111" has a centre hole 113 which is shaped for the insertion and removal of a bayonet type joint - onto the shaft 301. Therefore, the first advantage of the said embodiment is evident, consisting in that it allows complete protection of the motor unit against the probable penetration of flour or of the dough, due to the double protection of the shaft formed by sleeve ~i~13'~
107 and at the cap-like pinion 111.
The thrust means, consisting of a blade-like member 114 with lower surface 114' curved as shown in Fig. 4 and is radially and resiliently mounted on the lower area 111' of the pinion. The thrust means has a se~tion such as to form a side vertical plane.
The pinion 111 is provided with a radial pin 115, the free end of which is internally hollow and threaded. A flat spring 116 bears through a slot 118 of the blade-like member 114.
A through hole 117 and shaped slot 118, in member 114 provides for insertion of the pin 115 and the spring 116, and member 114 is locked by the cap screw 119. The blade-like member 114 is therefore free tc move anguLarly about the said pin 115 but against the action of the said spring 116, which tends to keep rear profile of member ~14 pressed against the bottom of the bowl 100. The particular shaping of the said member 114 and of the means for mounting it on the pinion 111 prevents the penetration of flour or portions of mixture into the through hole 117 and the slot 118, which could otherwise jam the blade-like member 114 itself.
On the lower area 111' of the pinion, diametrically opposite the thrust member 114 - a radial slant memher 120, suitable for removing dough from the bottom of the bowl 100 against it, thus improving the mixing and the thrust operations.
In the upper area 111" of the pinion - with a smaller diameter - two or more slanted mixing blades 130 are provided, operating as known in the art and suitable for obtaining the blending of the said ingredients.
134;~1 The extrusion unit 2 comprises an outer body of cylindrical - shape - generally referenced 200 - within which the screw 210 suitable for transferring and for co~pressing the mixture formed against the outlet plate 220 is forced.
The outer body 200 is advantageously made in.moulded plastics and it has a substantially parallelepiped shape - which can be inserted and withdrawn from the space 42 of the frame body 4 of the machine - and an internal cylindrical cavity 201 open in correspondence with the outlet plate 220 and lockable through a threaded ring nut 221. The opposite end has a hole 202 for the passage of the shaft 211 of the said screw 210, and its joint on the take-off shaft 302 of the motor-redu~er.
The outer upper surface of the said body 200 has a first recess 203 shaped in such a manner as to receive only partially the bottom of the mixing bowl 100, passing through the connection opening 43 of the space 41, and in addition an opening- 204 in correspondence with the opening 104 of the bowl 100, the s~id opening being adjusted by means of the slide member 205 which latter slides within a horizontal slit 206 in the upper wall of the body 200.
With the purpose of facilitating the location of the body . 200 within the space 42, its lower surface has a guide relief member (not shown) co-operating with a transverse recess 207 made. on the lower surface of the spool type body 200, which moreover is locked ~
during the operati.on - by the joint of the shaft 211 of the screw on the take-off shaft 302 of the motor reducer.
Therefore, the joint between the body 200 and the mixing bowl 100 prevents the outflow of the mixture in its passage from the - mixing unit 1 to the extrusion unit 2.
:
1~139~
The screw 210 - illustrated in detail in figs. 7 and 8 -has on its terminal area, adjacent the output plate 220, a f~rther thread 212 intermediate respect with the main thread 213; this allows, in addition to a better distribution of the mixture against the plate 220, for a reduction of the axial thrust thus improving the functional characteristics of the screw itself, and in particular reducing the power absorbed.
According to another embodiment of the machine of the present invention, a cover having a feed openina is assembled on the bowl of the mixing unit. The mouth of the opening is formed by vertical walls sticking out of the external surface of the cover, the feed opening communicating with a channel conveyor oriented in the direction of the mixing means rotation, on the bottom of said channel conveyor being present a tooth to break the yolk of the eggs in the feeding.
