Abstract
Abstract A self-contained agitating apparatus, primarily useful for batch processing a multiplicity of objects suspended in a fluid and contained in a vessel that is oscillated by a remote and stationary prime mover, to cause said objects to progressively move through a toroidal path and thereby roll into and out of interengagement and into and out of engagement with the vessel walls, and which action is enhanced by the presence of abrasives added to the fluid and/or batch for the purpose of deburring, polishing and the like. Secondarily, the apparatus is useful for lapping objects upon a plate and by means of the above said oscillatory action, said secondary utility being concurrent with said primary utility and operative simultaneously in the one apparatus.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
104 words
An agitator for gyratably moving objects and including, a stationary frame, a vessel with a bottom and for containing the load and with a cover in supported engagement thereon, a carriage having a central hub with a shaft journaled therein and carrying an exposed sheave, the carriage being in fixed supporting engagement with the vessel, yieldable support means extending between and positioning the vessel supporting carriage upon the frame, gyrating means comprising a laterally offset flyweight fixed to the shaft, and drive means to revolve the shaft, and a lapping plate carried by said cover and centered over the axis of the said shaft.
Claim 2
Dependent Claim
104 words
An agitator for gyratably moving objects and including, a stationary frame, a vessel with a bottom and for containing the load and with a cover in supported engagement thereon, a carriage having a central hub with a shaft journaled therein and carrying an exposed sheave, the carriage being in fixed supporting engagement with the vessel, yieldable support means extending between and positioning the vessel supporting carriage upon the frame, gyrating means comprising a laterally offset flyweight fixed to the shaft, and drive means to revolve the shaft, and a lapping plate carried by said cover and centered over the axis of the said shaft.
Claim 3
Dependent Claim
45 words
The agitator for gyratably moving objects as set forth in claim 1 wherein the cover has a peripheral weir, and wherein a lapping plate is carried by said cover within the surrounding confines of said weir and centered over the axis of the said shaft.
Claim 4
Dependent Claim
73 words
The agitator for gyrateably moving objects as set forth in claim 1 wherein the gyrating means comprises a laterally offset upper flyweight fixed to the shaft and positioned substantially above the bottom of the vessel and comprises a laterally offset lower flyweight fixed to the shaft and positioned at the bottom of the vessel, and wherein a lapping plate is carried by said cover and centered over the axis of the said shaft.
Claim 5
Dependent Claim
90 words
The agitator for gyratably moving objects as set forth in claim 1 wherein the gyrating means comprises a laterally offset upper flyweight fixed to the shaft and positioned substantially above the bottom of the vessel and comprises a laterally offset lower flyweight fixed to the shaft and positioned at the bottom of the vessel, wherein the cover of the vessel has a peripheral weir, and wherein a lapping plate is carried by said cover within the surrounding confines of said weir and centered over the axis of the said shaft.
Claim 6
Dependent Claim
153 words
An agitator for moving a load of fluid objects through toroidal low amplitude vibratory motions and including, a load carrying vessel of vertically disposed hollow configuration, a carriage having a central hub with a shaft journaled vertically therethrough, the carriage being in fixed supporting engagement with the vessel, a support means comprised of a plurality of circumferentially spaced rings of deformable high amplitude impedance yieldable plastic material and each disposed between the carriage and support therefor in a radial plane relative to said shaft and fastened to the carriage and said support therefor at their oppOsite peripheries and positioning the vessel supporting carriage, a gyrating means comprising at least one offset flyweight fixed to the shaft, and drive means to revolve the shaft and flyweight carried thereby to gyrate the same and the carriage and the vessel impressing low amplitude movements thereupon and below the high amplitude deformation impeded by said support means.
