Abstract
Abstract A mixing machine for a flowable material is provided with a mixing vessel from the horizontal bottom wall of which extends downwardly a hollow cylindrical guide provided with a lateral discharge nipple. A tubular housing extends slidably through the guide and extends with its upper end into the mixing vessel and is covered at this upper end by an annular funnel-shaped member and below the same has radial discharge apertures. A motor driven rotor in the upper part of the annular housing discharges the material fed into the funnel through the radial discharge apertures which in one adjusted position of the housing communicate with the interior of the mixing vessel while in another adjusted position of the housing communicate with the discharge nipple on the hollow cylindrical guide.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
144 words
A mixing machine for flowable material to be mixed and provided with a mixing vessel and a mixing device comprising a rotor for revolving the material in said mixing vessel and a housing surrounding said rotor and rotatably supporting the same, said housing having at least one inlet aperture and one or more discharge apertures, wherein the improvements comprise a hollow guide attached to the mixing vessel, means slidably attaching said guide to said housing, a discharge means on said guide, and means for adjusting said housing relatively to said vessel and said guide attached thereto so that in one end position of said housing the material is revolved in said mixing vessel by said rotor, while in another end position of said housing the mixed material is discharged from said mixing vessel by said rotor through said discharge apertures into said discharge means.
Claim 2
Dependent Claim
144 words
A mixing machine for flowable material to be mixed and provided with a mixing vessel and a mixing device comprising a rotor for revolving the material in said mixing vessel and a housing surrounding said rotor and rotatably supporting the same, said housing having at least one inlet aperture and one or more discharge apertures, wherein the improvements comprise a hollow guide attached to the mixing vessel, means slidably attaching said guide to said housing, a discharge means on said guide, and means for adjusting said housing relatively to said vessel and said guide attached thereto so that in one end position of said housing the material is revolved in said mixing vessel by said rotor, while in another end position of said housing the mixed material is discharged from said mixing vessel by said rotor through said discharge apertures into said discharge means.
Claim 3
Dependent Claim
73 words
A mixing machine according to claim 1, in which said means for adjusting said housing comprising means which adjust said housing and said motor and rotor in axial direction relatively to the axial direction of said mixing vessel and said guide attached thereto, whereby the discharge apertures in said housing are adapted to be selectively brought into communication with the interior of said mixing vessel and with said discharge means on said guide.
Claim 4
Dependent Claim
40 words
A mixing machine according to claim 1, in which said housing comprises a tubular member, one end of which extends into said mixing vessel while the other end of said housing has a motor attached thereto for driving said rotor.
Claim 5
Dependent Claim
79 words
A mixing machine according to claim 1, including a member comprising an inlet funnel arranged within said mixing vessel and attached to a portion of the housing extending into said mixing vessel while another portion of said housing being surrounded by said hollow guide, said member having a circular circumference and is adapted to be axially moved with said housing in sliding engagement with the interior wall of said hollow guide when said housing is moved to discharging position.
Claim 6
Dependent Claim
30 words
A mixing machine according to claim 1, in which said means for adjusting said housing permits an arresting of the same in any position between said two mentioned end positions.
Claim 7
Dependent Claim
119 words
A mixing machine according to claim 1, in which said means for adjusting said housing comprises means for rotatably adjusting said housing relatively to said hollow guide which is arranged to surround said housing, said hollow guide being provided with discharge apertures which are in communication with the interior of said mixing vessel and which in the mixing position of said housing are in registration with corresponding apertures in said housing, said last-named apertures upon a rotative adjustment of said housing being adapted to be moved gradually out of registration with said discharge apertures, said housing having other apertures which when said discharge apertures of said guide are closed by said housing are in communication with said discharge means.
Claim 8
Dependent Claim
109 words
A mixing machine according to claim 6, in which said housing has a hollow cylindrical wall which surrounds said rotor and that said apertures are arranged in said cylindrical wall which is surrounded by a cylindrical waLl of said hollow guide having said discharge apertures therein, and that superimposed plane annular walls of said housing and said hollow guide and through the center of which extends a shaft carrying the rotor are provided with apertures adapted to be moved upon relative rotative adjustment of housing and guide in and out of registration for establishing communication between the interior of said mixing vessel and said discharge means via said rotor.
Claim 9
Dependent Claim
48 words
A mixing machine according to claim 7, that the end face of said annular wall of said housing has mounted thereon an annular member provided with a central conical aperture serving as a funnel for feeding the material to be mixed in said mixing vessel to said rotor.
Claim 10
Dependent Claim
36 words
A mixing machine according to claim 7, including means to secure said motor to the end of the housing which is disposed opposite the end of the housing which is provided with said hollow cylindrical wall.
Claim 11
Dependent Claim
29 words
A mixing machine according to claim 7, in which the apertures in said plane annular walls of said housing and said hollow guide are of substantially the same size.
Claim 12
Dependent Claim
35 words
A mixing machine according to claim 7, in which the apertures in said hollow cylindrical wall of said housing and in the surrounding cylindrical wall of said hollow guide are substantially of the same size.
Claim 13
Dependent Claim
21 words
A mixing machine according to claim 7 including sealing members between the cylindrical walls of said housing and said hollow guide.
Claim 14
Dependent Claim
125 words
A mixing machine according to claim 6, in which said housing has a hollow cylindrical wall which surrounds said rotor and that said apertures are arranged in said cylindrical wall which is surrounded by a cylindrical wall of said hollow guide having said discharge apertures therein, and that superimposed plane annular walls of said housing and said hollow guide and through the center of which extends a shaft carrying the rotor are provided with apertures adapted to be moved upon relative rotative adjustment of housing and guide in and out of registration for establishing communication between the interior of said mixing vessel and said discharge means via said rotor, said annular member being fixedly attached to said annular wall of said housing to rotate therewith.
