Abstract
Abstract A rotating or rocking rack device for test tubes or vials. The rack device consists of a support on which a shaft is rotatably mounted, the shaft having clips for supporting test tubes or vials. A bidirectional motor is mounted on the support and is connected directly to the shaft. The shaft has an arm which can be adjusted to engage the housing of the motor, causing the motor to oscillate the shaft, or it can be adjusted to clear the housing, whereby the motor will rotate the shaft continuously in one direction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
91 words
An agitating rack device for containers comprising support means, shaft means rotatably mounted on said support means, means to secure containers to said shaft means, a bidirectional motor mounted on said support means, said motor being of a type which automatically reverses responsive to encountering an obstacle, means drivingly coupling said motor to said shaft means, and abutment means on the shaft means engageable with the support means during rotation of said shaft means to cause reversal of said motor and reversal of the direction of rotation of said shaft means.
Claim 2
Dependent Claim
91 words
An agitating rack device for containers comprising support means, shaft means rotatably mounted on said support means, means to secure containers to said shaft means, a bidirectional motor mounted on said support means, said motor being of a type which automatically reverses responsive to encountering an obstacle, means drivingly coupling said motor to said shaft means, and abutment means on the shaft means engageable with the support means during rotation of said shaft means to cause reversal of said motor and reversal of the direction of rotation of said shaft means.
Claim 3
Dependent Claim
37 words
The rack device of claim 1, and means to at times adjust said abutment means to a nonengaging position with respect to said support means, whereby to allow continuous rotation in one direction of said shaft means.
Claim 4
Dependent Claim
47 words
The rack device of claim 2, and wherein said abutment means comprises rotatably adjustable rod means mounted on said shaft means, said rod means being provided with a projection spaced from the shaft means and being engageable with said support means during rotation of the shaft means.
Claim 5
Dependent Claim
32 words

Claim 6
Dependent Claim
22 words
The rack device of claim 4, and wherein said projection comprises a laterally extending arm at the end of said rod means.
Claim 7
Dependent Claim
36 words
The rack device of claim 5, and wherein said support means includes a housing surrounding said motor, said laterally extending arm being engageable with portions of said housing to cause said motor to reverse its direction.
Claim 8
Dependent Claim
30 words
The rack device of claim 1, and wherein said shaft means comprises a square shaft and said container-securing means comprises spring clips secured to the sides of said square shaft.
Claim 9
Dependent Claim
23 words
The rack device of claim 7, and wherein the spring clips are arranged in pairs secured to opposite sides of said square shaft.
Claim 10
Dependent Claim
32 words
The rack device of claim 8, and wherein said pairs of spring clips are secured to alternate pairs of opposite sides of the square shaft along the length of said square shaft.
Claim 11
Dependent Claim
93 words
The rack device of claim 6, and wherein said support means comprises a generally U-shaped rigid member having a bottom wall and upstanding end walls, said motor and housing being mounted on one of said end walls, said shaft means comprising a square shaft drivingly coupled at one end to said motor, means on the other end wall pivotally supporting the other end of said square shaft, said container-supporting means comprising pairs of spring clips secured to alternate pairs of opposite sides of the square shaft along the length of said square shaft.
