Abstract
Abstract A vibratory machine of the bowl type is disclosed having a spring mounted bowl for containing a workload, such as parts and media for deburring them, and a vibratory mechanism rigidly attached thereto having a single eccentric mass or weight at its lower point. The single mass is rotated about the central vertical axis of the bowl and is positioned at a greater distance below the null point than the center of the workload is above that point to cause vibratory gyroscopic motion to be imparted to the workload with little external vibration and with low force and wear on the vibratory mechanism.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
In a vibratory finishing machine of the type having a bowl into which a workload may be charged for being subject to continuous vibration, the bowl having a workload center, and which machine includes a base to which a sprung mass including at least the bowl, is resiliently supported such that a vibratory null point is defined a distance below the workload center, the improvement comprising: a vibratory mechanism coupled to the bowl and comprising only a single rotatable eccentric mass or weight mounted for rotation about a point which center of rotation is located at a distance below the null point, which distance is greater than said distance between the workload center and the null point; and means for rotating said eccentric mass or weight.
Claim 2
Dependent Claim
126 words
In a vibratory finishing machine of the type having a bowl into which a workload may be charged for being subject to continuous vibration, the bowl having a workload center, and which machine includes a base to which a sprung mass including at least the bowl, is resiliently supported such that a vibratory null point is defined a distance below the workload center, the improvement comprising: a vibratory mechanism coupled to the bowl and comprising only a single rotatable eccentric mass or weight mounted for rotation about a point which center of rotation is located at a distance below the null point, which distance is greater than said distance between the workload center and the null point; and means for rotating said eccentric mass or weight.
Claim 3
Dependent Claim
22 words
The invention of claim 1, wherein: said rotating means is selectively variable to rotate said eccentric mass (22M) at different rotational speeds.
Claim 4
Dependent Claim
41 words
The invention of claim 1, wherein: said vibratory mechanism includes a generally vertical shaft (22S) having one end affixed to said mass (22M) said shaft being journaled in bearings (22B) to a housing (22T, 23) rigidly affixed to the bowl (12).
Claim 5
Dependent Claim
57 words
The invention of claim 3, wherein: said rotating means includes: a motor (29) mounted to the base; a drive pulley (28) coupled to said motor and driven thereby; a driven pulley (26) coupled to said shaft for turning it and positioned approximately at the null point; and a pulley belt connecting the drive pulley and driven pulley.
Claim 6
Dependent Claim
28 words
The invention of claim 3, wherein: said rotating means includes: a motor (29'') rigidly mounted to the bowl (12) and having its rotor coupled to rotate said mass.
Claim 7
Dependent Claim
33 words
The invention of claim 5, wherein: said motor is controlled by means (42) for varying its speed mounted off of the sprung mass, and coupled thereto by means of a flexible cable (48).
Claim 8
Dependent Claim
64 words
The invention as defined in claim 1, wherein: said vibratory mechanism is part of the sprung mass and is rigidly coupled to said bowl to impart movement to it and its workload content; the null point, workload center and center of rotation of said mass lie approximately along the same approximately vertical axis; and said eccentric mass is mounted for rotation about said axis.
Claim 9
Dependent Claim
47 words
The invention of claim 7, wherein the ratio between the distance (d) from the null point to the workload center and the distance (D) from the null point to the center of rotation of said rotatable eccentric mass (22M) is in the range between 1 and 6.
Claim 10
Dependent Claim
123 words
The invention of claim 8, wherein: said vibratory mechanism includes a generally vertical shaft (22S) having one end affixed to said eccentric mass (22M) said shaft being journaled in bearings (22B) to a housing (22T, 23) rigidly affixed to the bowl (12); and said rotating means includes: a Motor (29) mounted to the base: a drive pulley (28) coupled to said motor and driven thereby; a driven pulley (26) coupled to said shaft for turning it and positioned approximately at the null point; a pulley belt connecting the drive pulley and driven pulley; and said rotating means is selectively variable at infinitely small increments over a range of speeds by means of having said drive pulley of the manually variable effective diameter type.
Claim 11
Dependent Claim
91 words
The invention of claim 8, wherein: said vibratory mechanism includes a generally vertical shaft (22S) having one end affixed to said mass (22M) said shaft being journaled in bearings (22B) to a housing (22T, 23) rigidly affixed to the bowl (12); said rotating means includes: a motor (29'') rigidly mounted to the bowl (12) and having its rotor coupled to rotate said mass; and said motor is controlled by means (42) for varying its speed mounted off of the spring mass, and coupled thereto by means of a flexible cable (48).
