Abstract
Abstract A machine for agitating an article such as a container of small parts and an abrasive medium as employed in deburring or otherwise finishing the small parts. The container is rigid with a platform having a circular periphery and is driven by a flexible torque transmission element secured centrally of the circular periphery. The periphery rests on a table that has a central opening for the torque transmission element, and the point of contact between the circular periphery and the table makes an orbital path around the opening. The height of the table is adjustable in order to vary the configuration of the orbital path. The torque transmission has an eccentric element whereby the orbital path can be adjusted to be eccentric of the opening thus affording variation of the degree of agitation to which the container and contents are subjected.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
138 words
A machine for agitating an article comprising means defining a generally horizontal substantially planar non-rotatable surface, said surface defining means having an opening therein, flexible torque transmission means extending through said opening, an article supporting platform and means for attaching said platform to said torque transmission means above said surface, said attaching means including means for affording rotation of said platform relative said torque transmission means, said platform having a generally circular rim generally concentric with said rotation affording means, said flexible torque transmission means flexing to permit a peripheral region of said circular rim to bear on said surface, means below said surface for driving said torque transmission means so that said peripheral region of said circular rim describes a closed path on said surface around said opening, and means for securing the article to said platform.
Claim 2
Dependent Claim
138 words
A machine for agitating an article comprising means defining a generally horizontal substantially planar non-rotatable surface, said surface defining means having an opening therein, flexible torque transmission means extending through said opening, an article supporting platform and means for attaching said platform to said torque transmission means above said surface, said attaching means including means for affording rotation of said platform relative said torque transmission means, said platform having a generally circular rim generally concentric with said rotation affording means, said flexible torque transmission means flexing to permit a peripheral region of said circular rim to bear on said surface, means below said surface for driving said torque transmission means so that said peripheral region of said circular rim describes a closed path on said surface around said opening, and means for securing the article to said platform.
Claim 3
Dependent Claim
33 words
A machine according to claim 1 including means for adjustably raising and lowering said surface defining means relative to said torque transmission means so as to vary the configuration of said closed path.
Claim 4
Dependent Claim
63 words
A machine according to claim 1 wherein said torque transmission means comprises a rigid body, upper and lower pivot shafts journalled in said body at spaced apart locations thereon, means for operatively connecting said driving means to said lower shaft so that said body is rotated by said driving means, and means for operatively connecting said rotation affording means to said upper shaft.
Claim 5
Dependent Claim
21 words
A machine according to claim 3 wherein said upper and lower shafts reside in respective upper and lower spaced apart planes.
Claim 6
Dependent Claim
26 words
A machine according to claim 4 wherein said upper and lower shafts are disposed so that their respective longitudinal axes are substantially perpendicular to one another.
Claim 7
Dependent Claim
26 words
A machine according to claim 4 wherein said upper and lower shafts are disposed so that their respective longitudinal axes are substantially parallel to one another.
Claim 8
Dependent Claim
33 words
A machine according to claim 3 wherein the axis of said lower pivot shaft is offset from the axis of said upper shaft so that said path is eccentric of said surface opening.
Claim 9
Dependent Claim
39 words
A machine according to claim 7 including means for adjusting the position of said lower shaft connecting means along the lower pivot shaft so as to afford adjustment of the degree of eccentricity of said path relative said opening.
Claim 10
Dependent Claim
35 words
A machine according to claim 3 including means for rotatively resiliently biasing said upper pivot shaft relative said rigid body to resiliently urge said peripheral region of said circular member into contact with said surface.
Claim 11
Dependent Claim
34 words
A machine according to claim 1 wherein said article securing means includes a rigid impervious container, said container having an access opening for affording introduction of parts and surface finishing material into said container.
Claim 12
Dependent Claim
29 words
A machine according to claim 10 in combination with a closure member for said opening and means for removably securing said closure member in sealing relation to said opening.
Claim 13
Dependent Claim
34 words
A machine according to claim 1 wherein said torque transmission driving means includes means for adjusting the rotative speed of said driving means to afford adjustment of the force of agitation on the article.
Claim 14
Dependent Claim
20 words
A machine according to claim 1 wherein said horizontal surface forming means includes a resilient high friction layer laminated thereto.
