Various other objects and advantages of the present in vention will be readily apparent from the following detailed description when considered in connection'with the accompanying drawing forming a part thereof and in which:
FIGURE 1 is a perspective view of the apparatus ernbodied in the present invention;
FIGURE 2 is an enlarged fragmentary detail View taken along lines 2-2 of FIGURE 1;
FIGURE 3 is a fragmentary detail view illustrating the rotor head of the apparatus inclined at an angle with the drive shaft of the apparatus;

' FIGURE 5 is an enlarged view of a test tube carried in one of the clip means embodied in the present invention illustrating the figure eight motion followed by the liquid.
contents in the tube; and
FIGURE 6 is an enlarged detail view of the adjustable clip means embodied in the present invention. Referring to the drawings, the reference numeral 1 generally designates a rotating apparatus having a base or stand 11 with horizontally extending legs 12 on the front side ISthereof to provide stability. The base or frame 11 has a substantially horizontal lower portion 14 with a vertical box section 15 extending upwardly frornone end thereof. The enclosed box section 15 is provided with an upstanding or vertical member 16 adjacent the inner side or end. thereof forming a trunnion-support or bracket through which is threaded an adjustable horizontal screw member or trunnion member 17 having a head 18'. The screw member 17 extends through and into the sidewall 19 of a motor box or housing 20. The motorbox 20 is a truncated prism though it is readily understoodit can have other configurations if desired. A motor is housed in the motor box 20 and is provided with a shaft 21 that extends out of the removable front plate 23 of the box.
The motor and the motor box 20 are supported by the 'screw member 17. The screw member 17-that extends through the trunnion support or carriage 16 can tilt the motor and the motor shaft 21 in any direction through 360 degrees merely by loosening the screw member 17 and. rotating or turning the motor box 20-by hand to any desired angle and thereafter tighteningthe head of the screw member 17 against 16 by threading it into the motor box in order to rigidly fix the position or angle of p A rotatable'circular disc member or head28 is detach ably connected to the front end of the shaft 21 by a knurled screw member 29 having a threaded shaft 30 Y which threads into an internally threaded recess or bore 31 in the front end of. the shaft. The rotatable head 28 is provided with a central aperture or opening 33 therein. The opening 33 is substantially larger than the outside diameter of the shaft 21 so that a substantial gap or space 34 is disposed between the internal diameter of the rotor head 28 and the outer diameter of the shaft 21 as is clearly illustrated in FIGURES 2 and 3 for purposes hereinafter described. The rotator head 28 is fixed to shaft 21 so as to be rotated or driven thereby by merely threading the screw member 29 against the rotor headso that the rotor head abuts the outer face or front wall as of the collar. When it is desired to remove the rotor head 28 from the shaft 21, it is merely necessary to unthread the screw member 29 from the recess 31.-and remove it and lift off the head 28 from the shaft, in order to replace the head with a different type of rotatable head or a different size rotatable head as is desired.
The inner or rear face 37 of the rotor head is provided with a set screw 38 therein for setting the rotorhead at an inclined angle with respect to the axis of and the shaft 21 as illustrated in FIGURE 3. When the rotor head 28 is desired to be set at a 90 degree angle with the shaft 21 as illustrated in FIGURE 2 so the axis of the head and the shaft coincide, the set screw 38 is positioned in the slot 27 so that the inner face or wall 37 of the rotor 28 abuts the corresponding face 36 of the collar 25.
When it is desired to dispose the rotor head 28 at an inclined angle with the shaft 21 so the axis of the head and the shaft do not coincide, the screw member 29 is loosened and the rotor head is turned around 180 degrees from a position shown' in FIGURE 3 so that the set screw 38 is positioned in the recess 26 adjacent the top of the collar 25. The bottom of the recess 26 provides a shoulder 39 against which the head 38 of the set screw is positioned. The angle with reference of the shaft can be determined by a suitable adjustment of the position of' the set screw 38. Thereafter,'the screw member 29 is threaded home in the recess 31 until it abuts the outer wall 40 of the head 28 and the inner wall 37 of the head abuts the corresponding outer Wall 36' of the collar. The slot 27 and the recess 26 prevent the head28 from rota ing with respect to the drive shaft 21 when the set screw is positioned in either of these openings.
The front face 40 of the head is provided with a plurality of'clip members 41 disposed around the outer portion thereof in spaced relationship with one another and detachably secured to the rotatable head by individual screws 42 disposed in the horizontal portion .of each clip member. The face 40 is also provided with a plurality of circumferentially spaced recesses 35 therein for inserting hypodermic syringes and the like,v therein; The clip members 41- are substantially U-shaped and consist of two identical outwardly extending resilient legs 43 bowed as indicated at 44 adjacent the'inner end thereof and having an enlarged bow 45 adjacent the outer end thereon with outwardly extending tips or rims 46. The bowed portion 43' is-adapted to spread apart to receive a test tube, neck of. a bottle, flask or the like. such as holding the test tube 47 within a clip so that it can be rotated by the rotatable head 28 when the motor is in operation. The base 11 is provided with an on and off electrical switch 46 for operating'the motor. The box section" 15 also contains the leads to the motor and from the motor and means for connecting the apparatus toa wall socket or source .of power (not'shown).
The screws 42 permit the clips. to be readilydetached from the front wall or face 40 of the head to be replaced with different size clips'if desired for carrying different,
size test tubes or flasks of other shapes. The adjustable screws 42 also permit the clips to be disposed or turned toany desired position with respectto the head. 28.
The circumferential rim 50 ofthe head is provided with a plurality of identical test tube holding clip members41. The clip members 41 are alsoconnected to the head by the screws 42 so that the clip members may be readily attached to and disconnected from the head.
The adjustable clip members 41 on the circumferential rim 50 permit the clips to be inclined at an angle with the plane of the head 28. As shown in FIGURE 1 the peripheral clips 41 are all disposed at an inclined angle with the plane passing through the head 28, which plane is parallel to the sidewall or faces 40 and 37 of the head. The disposition of the tube clips 41 at an angle with respect to the head 28, as distinguished from the clips when they are turned so as to be in the same plane with the head'28 parallel thereto, permits the test tube carried by a clip 41 to be turned from, for example, an'uprig'ht position as indicated by the position 51 in FIGURE 1, toward a horizontalposition as indicated at 52, toward a downward or inverted position indicated at 53, to a reverse horizontal position as indicated at 54, and to be progressively returned to its original position at 51. Thus, in the sequence of rotation from the position at 51 through the positions around the entire periphery of the head, the test tube may be upside down and back to its original rightside up position in onerevolution in order to mix and agitate the contents carried within the tube. The provision of the plurality of clips disposed around the entire periphery of the head permits a large quantity of tubes and flasks or the like to be mixed simultaneously. The offsetting of the head 28 or tilting its axis at an angle that is inclined with respect to the axis of the shaft 21, causes the tubes while being turned from a rightside up position to an upside down position and back to its initial position, to be wobbled back and forth, or in other words, to be moved closer to and away from the face 7 plates 23 of the motor housing so that the fluid or liquid content carried in the tube 47 is agitated or has a motion in a figure eight configuration as illustrated by the direction of the arrows in FIGURE 5. Thus, the motion of the liquid or contents of the tube is such that-the liquid follows in a figure eight path oftravel which avoids any sedimentation or foaming of the liquid therein and introduces a gentle agitation. in medical application such asthe agitation of blood in heparinized syringes and the like.
Thus, with the present invention an apparatus is pro-- vided in which a number of test tubes, or other types of containers, can be rotated at the same time to'impart a figure eight path of travel of the contents therein by adjusting the clip members 41 at an inclined angle with the head 28 and adjusting the head 28 atm inclined angle with the shaft 21 as illustrated in FIGURE 3, so that the .exact and precise desired types of agitation and mixing can be obtained.
The head further permits the contents of the tube to be agitated in other ways, such as mere rotation of the con tents of the tube, by disposing a tube clip in the same plane with the head and by disposing the head at right angles with the shaft 21 as-shown in FIGURE 2. It isfurther realized that the adjustable tilt of the motor box' 29 allows wide application by the operator for setting it to the correct angle for a particular test.
The tilting or setting of the rotatable'head at an oblique angle with respect to the longitudinal axis of the straight motor shaft, instead of a ninety degree angle, enables the fluid containers carried by the head to have imparted thereto versatilityin the agitation and mixing of the fluid in the containers. The foregoing flexibility together with positioning of the clips along the periphery of the face of the agitator head and along-the rim thereoftogether with the providing of recesses in the face of the rotator head to receive appropriate receptacles provides for remarkable flexibility in'types of mixing and agitation.
Inasmuch as various changes may bemade' in the particular form, location and arrangment of the parts of the apparatus disclosed without departing from the principles of the invention, it will'be understood that the invention This is particularly important is not to be limited except by the scope of the appended claims.
