The third lock member 32 is a horizontal tab. The third lock member 32 has'a flange 34 and a proximal facing surface 36. The third lock member 32 is formed by lancing a section of the spinner basket annular axial edge 22 and turning the lanced section inward towards the centerline of the assembly 10. Alternatively, the third lock member 32 may be made by other means known in the art.
The spinner basket 20 has a circumferal rib 38. The circumferal rib' 38 extends inwardly into the spinner basket 20.
The balance ring 40 fits within spinner basket 20. As seen in FIG. 3, there are cooperating members on the balance ring 40 located at the annular lower edge or annular axial edge 42 that operate with cooperating members on the spinner basket 20.
These cooperating members are in mating engagement when the balance ring 40 is moved adjacent the annular upper edge 22 of the spinner basket 20 and the balance ring 40 is rotated to engage cooperating members. The cooperating members for the balance ring 40 involve a second cam surface, second cam, or second cam structure 44; a second lock member or toothed member 46; and a fourth lock member or ribbed-structure member 52.
The second cam surface 44 is a portion of the balance ring 40 with decreasing radius. Alternatively, the second cam surface 44 is a ramp structure.

Alternatively, the second cam surface 44 may be any other structure known in the art that may engage another similarly shaped surface.
Upon the balance ring annular lower edge 42 is a second lock member 46. In this embodiment, the second lock member 46 is a toothed member. The second locked member 46, as seen in FIG. 5, includes a flange 48 and a flange axially facing surface 50. The flange 48 may be sized to be placed upon an extension surface 49 as seen in FIG. 5.
Alternatively, the flange 48 may be structured as a parallelogram tooth member as seen in FIG. 7, and extend without the use of an extension member 49.
Upon the balance ring annular lower edge 42 is a fourth lock member 52. In this embodiment, the fourth lock member 52 is a ribbed-structure member which has a flange 54 and a proximally facing surface S6. The flange 54 supports the proXima.lly facing surface 56 when in contact with the horizontal tab proximal facing surface 36.
The balance ring 40 has a bottom surface 58 that conforms to the spinner basket circumferal 38 of the annular upper edge 22 at a point where the first cam surface 24 meets the second cam surface 44. The balance ring 40 has an inner annular surface 60, and outer annular surface 62, and an annular.proximal edge or annular upper edge 64.
As seen in FIG. 3, the assembly 10 has a detached spinner basket 20 and balance ring 40. The balance ring is adjacent the upper annular edge 22 of the spinner basket 20.
Before assembly, these corresponding surfaces on the spinner basket 20 and the balance ring 40 are put in alignment. Specifically, the first cam surface 24 is placed into offset alignment with the second cam surface 44. First lock member 26 is placed into offset alignment with second lock member 46. Third lock member 32 is placed into offset alignment with fourth lock member 52. When these members are all in offset alignment the balance ring 40 fits within the spinner basket 20. In offset alignment the spinner tub may be removed as it is in an unlocked position with the spinner basket 20.
The spinner basket 20 and the balance ring 40 may be placed in a locked position by rotating the balance ring 40 relative to the spinner basket 20. In this embodiment, the balance ring 40 is moved counter clockwise to the spinner basket 20. Movement of the balance ring 40 counter clockwise to the spinner basket 20 engages the first cam surface 24 against the second cam surface 44. The engagement of first cam surface 24 and second cam surface 44 centers the balance ring 40 upon the spinner basket 20. In this position, the engagement of the cam surface creates circumferal resistance to further counter clockwise . movement of the balance ring 40 relative to the spinner basket 20.
In the locked position, the first lock member or first tab 26 engages the second lock member or toothed member 46. In the locked position, the first tab flange 28 engages the toothed member flange 48. The toothed member 46 is positioned such that the rotational counter clockwise movement allows for the flange 48 on the axial facing surface 50 to be moved relative to the first tab flange 28 on the first flange axial facing surface 30. This positioning allows for resistance of the balance ring 40 to move clockwise when the balance ring 40 is attached to the spinner basket. The first lock member 26 and the second lock member 46 in this embodiment have this preferred structure because the first cam' structure 24 and the second cam structure 44, working together, provide resistance to counter clockwise movement of the balance ring 40.
In the locked position the third lock member 32 engages the fourth lock member 52.
The third lock member 32 in this embodiment is a horizontal tab. The horizontal tab 32 fits over the ribbed-structure member or fourth locked member 52. In this embodiment, the ribbed-structure member includes a horizontal surface on the balance ring 40.
The horizontal tab 32 has a flange 34 with a second flange proximally facing surface 36 that is horizontal. When the balance ring 40 is rotated counter clockwise with respect to the spinner basket 20, the flange 34 and proximal facing surface 56 align to resist upward axial movement of the balance ring 40 relative to the spinner basket 20.
In operation, the spinner basket circumferal rib 38 contacts the balance ring bottom surface 58. When the balance ring 40 is rotated counter clockwise to the spinner basket 20, the spinner basket 20 maintains contact between spinner basket circumferal rib 38 and the balance ring bottom surface 58. This contact between the of cireumferal rib 38 and the bottom surface 58 prevents downward movement of the balance ring 40 relative to the spinner basket 20.
In the drawings and specifications there has been set forth a preferred embodiment of the invention, and although specific terms are employed, these are used in a generic descriptive sense only and not for purposes of limitation. Changes in the form and the proportion of parts as well as in the substitution of equivalents are contemplated as circumstance may suggest or render expedient without departing from the spirit or scope of the invention in the following claims.
Upon the balance ring annular lower edge 42 is a second lock member 46. In this embodiment, the second lock member 46 is a toothed member. The second locked member 46, as seen in FIG. 5, includes a flange 48 and a flange axially facing surface 50. The flange 48 may be sized to be placed upon an extension surface 49 as seen in FIG. 5.
Alternatively, the flange 48 may be structured as a parallelogram tooth member as seen in FIG. 7, and extend without the use of an extension member 49.
Upon the balance ring annular lower edge 42 is a fourth lock member 52. In this embodiment, the fourth lock member 52 is a ribbed-structure member which has a flange 54 and a proximally facing surface S6. The flange 54 supports the proXima.lly facing surface 56 when in contact with the horizontal tab proximal facing surface 36.
The balance ring 40 has a bottom surface 58 that conforms to the spinner basket circumferal 38 of the annular upper edge 22 at a point where the first cam surface 24 meets the second cam surface 44. The balance ring 40 has an inner annular surface 60, and outer annular surface 62, and an annular.proximal edge or annular upper edge 64.
As seen in FIG. 3, the assembly 10 has a detached spinner basket 20 and balance ring 40. The balance ring is adjacent the upper annular edge 22 of the spinner basket 20.
Before assembly, these corresponding surfaces on the spinner basket 20 and the balance ring 40 are put in alignment. Specifically, the first cam surface 24 is placed into offset alignment with the second cam surface 44. First lock member 26 is placed into offset alignment with second lock member 46. Third lock member 32 is placed into offset alignment with fourth lock member 52. When these members are all in offset alignment the balance ring 40 fits within the spinner basket 20. In offset alignment the spinner tub may be removed as it is in an unlocked position with the spinner basket 20.
The spinner basket 20 and the balance ring 40 may be placed in a locked position by rotating the balance ring 40 relative to the spinner basket 20. In this embodiment, the balance ring 40 is moved counter clockwise to the spinner basket 20. Movement of the balance ring 40 counter clockwise to the spinner basket 20 engages the first cam surface 24 against the second cam surface 44. The engagement of first cam surface 24 and second cam surface 44 centers the balance ring 40 upon the spinner basket 20. In this position, the engagement of the cam surface creates circumferal resistance to further counter clockwise . movement of the balance ring 40 relative to the spinner basket 20.
In the locked position, the first lock member or first tab 26 engages the second lock member or toothed member 46. In the locked position, the first tab flange 28 engages the toothed member flange 48. The toothed member 46 is positioned such that the rotational counter clockwise movement allows for the flange 48 on the axial facing surface 50 to be moved relative to the first tab flange 28 on the first flange axial facing surface 30. This positioning allows for resistance of the balance ring 40 to move clockwise when the balance ring 40 is attached to the spinner basket. The first lock member 26 and the second lock member 46 in this embodiment have this preferred structure because the first cam' structure 24 and the second cam structure 44, working together, provide resistance to counter clockwise movement of the balance ring 40.
In the locked position the third lock member 32 engages the fourth lock member 52.
The third lock member 32 in this embodiment is a horizontal tab. The horizontal tab 32 fits over the ribbed-structure member or fourth locked member 52. In this embodiment, the ribbed-structure member includes a horizontal surface on the balance ring 40.
The horizontal tab 32 has a flange 34 with a second flange proximally facing surface 36 that is horizontal. When the balance ring 40 is rotated counter clockwise with respect to the spinner basket 20, the flange 34 and proximal facing surface 56 align to resist upward axial movement of the balance ring 40 relative to the spinner basket 20.
In operation, the spinner basket circumferal rib 38 contacts the balance ring bottom surface 58. When the balance ring 40 is rotated counter clockwise to the spinner basket 20, the spinner basket 20 maintains contact between spinner basket circumferal rib 38 and the balance ring bottom surface 58. This contact between the of cireumferal rib 38 and the bottom surface 58 prevents downward movement of the balance ring 40 relative to the spinner basket 20.
In the drawings and specifications there has been set forth a preferred embodiment of the invention, and although specific terms are employed, these are used in a generic descriptive sense only and not for purposes of limitation. Changes in the form and the proportion of parts as well as in the substitution of equivalents are contemplated as circumstance may suggest or render expedient without departing from the spirit or scope of the invention in the following claims.
