Abstract
Abstract A separator for grain and similar products, which comprises a substantially vertical driver shaft having an upper end, and an eccentric driven shaft located above and inclined with respect to the driver shaft. The eccentric driven shaft has an upper end and a lower end, and a product receiving casing is located above and receives rotatably the upper end of the driven shaft, so as to wobble when the driven shaft orbits about driver shaft. The casing is arranged to assume the inclination of the driven shaft. An arrangement for transmitting motion from the driver shaft to the driven shaft is provided and the arrangement comprises a baseplate fixed to the upper end of the driver shaft and a supporting plate fixed to the lower end of the eccentric driven shaft. The baseplate includes a slide radially movable on the baseplate. Hinge means connect pivotally the baseplate to the supporting plate about two imaginary axes disposed at a substantially right angle relative to and independently from each other for setting the radial angle about one of the axes and the tangential angle about the other of the axes of the supporting plate relative to the baseplate, so that the supporting plate is pivotable about both axes into different positions of the eccentricity of the driven shaft independently of the adjustment of the inclination thereof. Also securing means are provided which cooperate with the hinge means for holding the supporting plate in any one of a plurality of different positions of inclination in two directions and eccentricity.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
261 words
A separator for grain and similar products, comprising a substantially vertical driver shaft having an upper end, an eccentric driven shaft located above and inclined with respect to said driver shaft, said eccentric driven shaft having an upper end and a lower end, a product receiving casing located above and rotatably receiving the upper end of said driven shaft, so as to wobble when said driven shaft orbits about said driver shaft, said casing being arranged to assume the inclination of said driven shaft, an arrangement for transmitting motion from said driver shaft to said driven shaft, said arrangement comprising a baseplate fixed to the upper end of said driver shaft and a supporting plate fixed to the lower end of said eccentric driven shaft, said baseplate including a slide radially movable on said baseplate, hinge means pivotally connecting said baseplate to said supporting plate about two imaginary axes disposed at a substantially right angle relative to and independently from each other for setting the radial angle about one of said axes and the tangential angle about the other of said axes of said supporting plate relative to said baseplate, so that said supporting plate is pivotable about both said axes into different positions of inclination with respect to said driver shaft, as well as into different positions of eccentricity of said driven shaft independently of the adjustment of the inclination thereof, and securing means cooperating with said hinge means for holding said supporting plate in any one of a plurality of different positions of inclination in two directions and eccentricity.
Claim 2
Dependent Claim
261 words
A separator for grain and similar products, comprising a substantially vertical driver shaft having an upper end, an eccentric driven shaft located above and inclined with respect to said driver shaft, said eccentric driven shaft having an upper end and a lower end, a product receiving casing located above and rotatably receiving the upper end of said driven shaft, so as to wobble when said driven shaft orbits about said driver shaft, said casing being arranged to assume the inclination of said driven shaft, an arrangement for transmitting motion from said driver shaft to said driven shaft, said arrangement comprising a baseplate fixed to the upper end of said driver shaft and a supporting plate fixed to the lower end of said eccentric driven shaft, said baseplate including a slide radially movable on said baseplate, hinge means pivotally connecting said baseplate to said supporting plate about two imaginary axes disposed at a substantially right angle relative to and independently from each other for setting the radial angle about one of said axes and the tangential angle about the other of said axes of said supporting plate relative to said baseplate, so that said supporting plate is pivotable about both said axes into different positions of inclination with respect to said driver shaft, as well as into different positions of eccentricity of said driven shaft independently of the adjustment of the inclination thereof, and securing means cooperating with said hinge means for holding said supporting plate in any one of a plurality of different positions of inclination in two directions and eccentricity.
Claim 3
Dependent Claim
100 words
The separator, as set forth in claim 1, wherein said hinge means for pivoting said supporting plate comprises three screwbolts extending through and connecting said slide with said supporting plate and being secured by nuts received by said screwbolts, two of said screwbolts are disposed on said other of said axes for setting said tangential angle of inclination, one of said screwbolts is disposed on said one of said axes for setting said radial angle of inclination, and the head of said screwbolts and said nuts have spherical faces for engagement with said slide and with said supporting plate, respectively.
Claim 4
Dependent Claim
73 words
The separator, as set forth in claim 2, wherein said slide and said supporting plate have a recess receiving the corresponding head of said screwbolts, said heads of said screwbolts have radial pins projecting therefrom and being received in radial grooves provided in said recess, in order to prevent rotation of said screwbolts, means for retaining said screwbolts in said slide, and said nuts include scale discs indicating the respective angles of inclination.
Claim 5
Dependent Claim
59 words
The separator, as set forth in claim 3, wherein each of said scale discs has a plurality of radially disposed grooves, and said supporting plate includes a spring biased ball cooperating with said radially disposed grooves, to form a resting means operating to secure the elected position of said nuts and sImultaneously operating as acoustic and touching setting assistance.
Claim 6
Dependent Claim
46 words
The separator, as set forth in claim 2, which includes additional supporting members disposed between said supporting plate and said slide, and holding a spherical cap at the lower end of said eccentric driven shaft in a recess of said slide complementary to said spherical cap.
Claim 7
Dependent Claim
16 words
The separator, as set forth in claim 5, wherein said additional supporting members comprise pressure springs.
Claim 8
Dependent Claim
45 words
The separator, as set forth in claim 1, which includes a guide pin rigidly secured to said slide, said supporting plate having a bore receiving said guide pin for preventing rotation of said supporting plate relative to said baseplate and about said eccentric driven shaft.
Claim 9
Dependent Claim
70 words
The separator, as set forth in claim 1, wherein said slide is guided along said baseplate by a dove tail connection, a screw spindle axially projecting from said slide and receiving a nut and a scale disc for setting a predetermined eccentricity and for receiving of the centrifugal forces during operation of said separator, and set screws provided in said baseplate for securing said slide in the respective set positions.
