F. AESCHBACH KNEADING,
July 24, 1934.
STIRRING, AND MIXING MACHlNE Filed July 2l, 1933 Patented July 24, 1934 UNITED STATES STIRRING, KNEADING, AND ltIIXING MACHINE Friedrich Aeschbach, Aarau, Switzerland Application July 21, 1933, Serial No. 681,636 In Switzerland August 2, 1932 2 Claims.
This invention relates to stirring, kneading and mixing machines comprising a central shaft and two rotatory implement shafts gyrating about said central shaft. With the hitherto known machines of this kind one of the gyrating implement shafts was arranged in parallel relationship to the central shaft and the other obliquely disposed thereto, and the implement shafts were adapted for alternate operation only.
In the machine according to the present invention, both gyrating implement shafts are obliquely disposed to the central shaft and the implements adapted for simultaneous operation without interfering with each other, the whole arrangement being such that the eiiiciency of operation of the machine is improved.
Since both oblique implement shafts act upon the material under treatment not alone in the horizontal but also in the vertical direction, the 20 machine according to the present invention is adapted not only to produce an improved mixing and kneading effect, as compared with the known machines, but also to expedite the work.
In the accompanying drawing a constructional form of the invention is shown by way of example only, in which Fig. 1 shows an elevation partly in section, and
Fig. 2 is a section through the vertical axis of the machine, on a larger scale.
Referring to the drawing, a gear wheel 1 is fixed on the driving shaft of the machine (which is not shown), this gear wheel meshing with a gear wheel 3 secured to a jack shaft 2. This shaft 2 is mounted for rotation at both of its ends in a 35 drive casing 5 by means of ball bearings 4, the casing 5 in turn being firmly connected to the machine frame 6. To the jack shaft 2 a pinion 7 is fixed at the side of the wheel 3, for cooperation with a gear wheel 9 secured to a central vertical shaft 8. For the purpose of suspending this vertical shaft 8 the upper end of the same is exteriorly threaded for engagement with an annular shoulder piece 10 having a slot 12 for clampingly securing this piece in position by means of a screw 11. 'Ihe annular shoulder piece 10 abuts against a ball bearing 13 which is carried by the casing 5. On the shaft 8 a bevel gear wheel 14 having an elongated nave 15 is mounted for rotation below the wheel 9. The wheel 3 is in mesh with a spur gear Wheel 16 which is rigid with the nave 15. The vertical shaft 8 is mounted in a ball bearing 17 inserted in the bottom of the casing 5. To the lower end of the central shaft 8 a carrier member 18 is connected and secured in position by a shoulder 19.
In the carrier member 18 two implement shafts 20, 21 are mounted for rotation in oblique relationship to the central shaft 8, the implement shafts thus being caused to gyrate about the 00 central shaft, when this shaft is rotated. The implement shaft 20 carries a pinion 22 which cooperates with a stationary sun wheel in the form of a bevel gear wheel 23 rmly secured to the bottom of the casing 5 for example by a 05 screw connection. To the other oblique implement shaft 21 a pinion 24 is fixed which is in mesh with the bevel gear wheel 14. The lower ends of the oblique shafts receive the implements 25, 26 for Working the material in the trough 27, 70 the implements being secured to these shafts for example by means of bayonet joints.
The oblique shaft 20 is rotated about its own axis by the gear wheel 22 rolling on the fixed beveled toothed rim 23, and the oblique shaft 21 75 is rotated about its axis by means of the gear wheels 16, 14 and 24. 'I'he arrangement is such that the two working implements for the material are rotated in opposite directions.
The driving wheel 1 can be imparted several 80 different speeds for example by means of a change speed gear (not shown) so that the speed of the implements can be adapted at any time to the nature of the Work to be performed.
Due to the fact that both implement shafts are obliquely disposed, the material subjected to mixing or stirring action and so forth is at the same time also alternately lifted which results for instance in a very effective stirring and mixing operation.
In the constructional example of the invention shown both implement shafts are inclined at the same angle to the central axis. Alternatively, the angle of inclination of the two shafts may be different. By varying the diameters of the trains 95, of gear Wheels between the main shaft and the jack shaft any desired relation of the number of revolutions of the implement shafts about their own axes to the number of revolutions of the gyrating movement of these shafts can be obtained in a simple manner.
I do not limit myself to the particular size, shape, number or arrangement of parts as shown and described, all of which may be varied without going beyond the scope of my invention as shown, described and claimed.
What I claim is:
1. In a stirring, kneading and mixing machine, in combination, a machine casing a trough for the reception of the material to be worked arranged in said casing, a shaft mounted for rotation in said casing in central relation above said trough, a mounting member secured to said central shaft for common rotation therewith, two implement shafts rotatably carried by said mounting member and obliquely disposed to said central shaft, an implement received by each of said oblique shafts and extending within said trough, said implements having a form to adapt them for simultaneous operation without interfering with each other, a gear wheel mounted for rotation on said central shaft, an elongated nave on said gear wheel, a jack shaft operatively connected with said nave and with said central shaft, for rotating the latter and said gear wheel on the same at different speeds, a driving gear wheel secured to each of said implement shafts, one of said driving wheels meshing with said gear Wheel on said central shaft, and a sun Wheel xed on said casing for the other of said driving wheels to roll on, when said central shaft and. said gear wheel on the same are rotated by said jack shaft.
2. In a stirring, kneading and mixing machine, in combination, a machine casing, a trough for the reception of the material to be worked arranged in said casing, a shaft mounted for rotation in said casing in central relation above said trough, a mounting member secured to said central shaft to rotate therewith, two implement shafts rotatably carried by said mounting member in downwardly converging disposition to each other and on opposite sides of said central shaft, an implement carried by each of said oblique shafts for common rotation therewith and extending Within said trough, driving means causing said implement shafts to gyrate about said central shaft, and means rotating said shafts about their own axes in opposite directions in timed relation adapting said implements to appreach on each other centrally of the trough with their paths in the form of bodies generated by revolution intersecting.
