Abstract A vibratory finishing machine having a fixed frame and a floating support resiliently mounted thereon, a finishing chamber mounted on the floating support, a gyratory motion-producing assembly affixed to the support eccentrically mounted on a shaft and a motor operatively coupled thereto. The finishing chamber is divided into two parts, one part rotatively mounted and having at least an inner vertical wall, and a stationary portion affixed to the floating support. A second motor is mounted in fixed relationship with the floating support and operatively coupled to rotate the rotatably-mounted portion of the chamber. The rotational or centrifugal rotation of the rotatably-mounted portion of the chamber provides greatly improved finishing efficiency of the apparatus. Additionally, the gyrational motion of the chamber produced by the first motor and accompanying eccentric weights may be used to provide automatic discharge of the parts, and may also be used for finishing parts operated either by itself or in combination with the centrifugal rotation produced by rotating the rotatable portion of the chamber.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
107 words
A process for finishing a part which comprises: (a) maintaining said part and a finishing material in an annular finishing chamber comprising members, one of which is rotatable with respect to the other, (b) rotating one of said rotatable members relative to the other to cause said part and finishing material to revolve and to move continually alternately between said rotating member and said other member for finishing said part, (c) applying gyrational motion to said finishing chamber to cause said part and finishing material to move forward with precessional motion within said chamber, and (d) separating said finishing material from said part and discharging said part.
Claim 2
Dependent Claim
107 words
A process for finishing a part which comprises: (a) maintaining said part and a finishing material in an annular finishing chamber comprising members, one of which is rotatable with respect to the other, (b) rotating one of said rotatable members relative to the other to cause said part and finishing material to revolve and to move continually alternately between said rotating member and said other member for finishing said part, (c) applying gyrational motion to said finishing chamber to cause said part and finishing material to move forward with precessional motion within said chamber, and (d) separating said finishing material from said part and discharging said part.
Claim 3
Dependent Claim
19 words
A process according to claim 1, wherein said rotational motion and gyrational motion are applied simultaneously in step (b).
Claim 4
Dependent Claim
29 words
A process according to claim 1, wherein said rotational motion is first applied and subsequently stopped, and said gyrational motion is subsequently applied to accomplish discharging of said part.
Claim 5
Dependent Claim
28 words
A process according to claim 1 wherein said chamber comprises an inner annular member and an outer annular member and said rotating comprises rotating said inner annular member.
Claim 6
Dependent Claim
20 words
A process according to claim 1, wherein said finishing chamber comprises a bottom, and said rotating includes rotating said bottom.
