Definitions

  • the described invention concerns apparatus for gently and continuously agitating the contents of one or more elongated containers such as sampling phials, which consists of a number of cylindrical rollers borne by a base structure and positively driven for rotation all in the same sense of direction on rotation axes which are parallel, the cylindrical axis of each roller being inclined to its rotation axis, so that a container placed in supporting contact with any two adjacent rollers is rotated and simultaneously rocked in two di- UNITED STATES PATENTS 520,205 5/1894 Heyligenstaedt 259/81 R 4 Claims, 2 Drawing Figures l r i I L- 7 RA 1* Q I a L l (1 RA I J 2 l i ll ,I I I l i? RA l 41 t r I l Q l i Jan;
  • This invention relates to mixer apparatus and in particular to apparatus for mixing or tumbling the contents of sealed or closed containers which are of circular (or approximately circular) cross section by rotating the containers and contents therein.
  • Such apparatus comprises a plurality of parallel, closely-spaced, rotatable rollers arranged in a horizontal plane and suitably geared together so that they rotate in synchronism and in the same sense of rotational direction when driven by a motor or other driving means.
  • a cylindrical container, or a container provided with two or more cylindrical bands, when placed between and supported by a pair of such rollers is caused to rotate when the rollers rotate, thereby tumbling the contents thereof.
  • two rollers rotat' ing eccentrically and such as to support a heavy drum or like container the rollers being frictionally interconnected so as to rotate more or less synchronously; but in such suggestion the eccentricity of the rollers was to be such that they were not parallel.
  • Samples of blood in sealed containers for pathological or other examination may conveniently be remixed, to ensure homogeneity immediately prior to examination, by such apparatus, but it is believed that if a gentle rocking or see-saw motion is imparted to the sample containers during rotation, thorough mixing of the sam ple results whilst avoiding formation of froth or even breakdown of, or damage to, the blood cells such as may occur with mixers that have been proposed having a more violent mixing action.
  • the apparatus be capable of thorough mixing of the contents of containers, but avoiding frothing of, or damage to, the contents, and that it be reliable in operation.
  • the present invention offers a very simple apparatus for the gentle agitation of such containers as glass specimen-tubes or phials used in'pathology or other kindred circumstances, by which a number of containers can simply be placed on the apparatus, which may well be continually running, and a number may be so placed virtually without regard to precise. size or proportions. When rotated and rocked, such frictional slip" as occurs is negligible.
  • apparatus for agitating the fluid contents of one or a plurality of elongated containers comprising a plurality of cylindrical rotors which are rotated on parallel axes and positively interengaged for rotation in the same sense of direction and at the same speed on such axes, the rotors having their individual cylinder axes at an angle to the rotational axes and at all times parallel each to the other.
  • each roller is provided with a spindle extending from its ends and supported for rotation in journal or roller bearings and, at least at one end, having positive driving means such as a pinion.
  • the extended spindles of a roller lie on the same axis and their axes are parallel; such axes are inclined identically, to the cylinder axes of the corresponding axes of the rollers, preferably the two ends of a roller are eccentric by an equal amount and at an angle of
  • the axes of the spindles are preferably all in one plane which plane is horizontal.
  • the surfaces of the rollers may be of frictional material such as rubber and their-spindles are preferably geared together positively by gear trains in order to provide synthronism in rotation and to impart rotation to each roller in the same sense of direction.
  • variable-speed driving means are provided is within the scope of the invention.
  • FIG. 1 is a. plan view of a mixer apparatus with the gear-train and motor exposed
  • FIG. 2 is a side elevation of the apparatusof FIG. 1.-
  • the spindles 2A lie onthe axis of rotation shown as RA in the drawings, but each spindle is eccentric with its associated roller end by an equal radial amount at each roller-end,-and'each spindle 2A is angularly displaced relatively to one, end of its roller by 180 relative to-that at the other end.T-hus, as seen in theside elevationof FIG. 2, the-cylindrical axis IJA of each roller 2 is inclined to the axis of rotation RA of each roller.
  • the spindles 2A ofthe roller ends adjacent to the bracket 4 extend rotatably through bearings 5 and each terminates in an identical gearwheel 7 fastened thereto by a transverse pin (not shown).
  • a driven gear 9 which meshes with adjacent gears 7 and thereby causes the rollers 2 to rotate when driven.
  • Gear 9 is fastened to motor-shaft 10 of electric motor M which may be of the shaded-pole type suitably geared internally to provide an output shaft speed of 60 R.P.M.
  • the motor M is fastened to baseplate l by means of fixing lugs or brackets (not shown).
  • a cover will normally be provided to enclose the motor and gears, but in the drawings this has been omitted for the purpose of clarity.
  • the spacing between bearings 5, and similarly between bearings 6 is greater than the diameter of a roller and so arranged that tubes C or other cylindrical container of compatible dimensions may be supported between any adjacent pair of rollers 2 merely having to be placed thereon.
  • sample-tube C In operation, the motion imparted to sample-tube C is rotary by virtue of the rotation of the rollers 2 with which it is frictionally engaged, and oscillatory in two dimensions by virtue of the geometry of the rollers and associated axles 2A.
  • Apparatus for agitating the fluid contents of elongate, substantially cylindrical containers comprising,
  • a base structure including a pair of spaced parallel supports
  • rollers each having a spindle on each end thereof respectively mounted in a pair of said bearings, said rollers being elongate of uniformly cylindrical configuration and extending substantially between the respective pairs of bearings, said spindles of each roller disposed coaxially and the spindle on at least one end being disposed eccentrically to the axis of that end, the rollers being disposed with said eccentric spindles at their corresponding ends and with their cylindrical axes parallel.
  • Apparatus according to claim 1 comprising an array of at least three rollers.
