Abstract
Abstract A vibrator is prevented from transmitting its vibratory motion to the vibrator holder, such, for example, as a handle, by interconnecting the vibrator and handle with a spring arranged so that the spring serves as a resilient cantilever. Amplitude of vibrations are enhanced without a corresponding increase in the amount of vibration transmitted to the handle by arranging the resilience of the spring and the mass of the vibrator to be resonant at the frequency of vibrations or at a submultiple of those frequencies.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
62 words
In a vibrator: (a) a mass; (b) motive means for importing vibratory motion to the mass; (c) a holder; and (d) interconnecting means for supporting said mass at a distance from said holder while insulating the holder in part from vibratory motion of said mass comprising a resilient arm in the form of a cantilever the cantilever comprising a coiled extension spring.
Claim 2
Dependent Claim
62 words
In a vibrator: (a) a mass; (b) motive means for importing vibratory motion to the mass; (c) a holder; and (d) interconnecting means for supporting said mass at a distance from said holder while insulating the holder in part from vibratory motion of said mass comprising a resilient arm in the form of a cantilever the cantilever comprising a coiled extension spring.
Claim 3
Dependent Claim
32 words
The invention defined in claim 1 in which said motive means comprises an electromagnetic structure having an element movable by magnetic force; said mass being connected to and movable with said element.
Claim 4
Dependent Claim
47 words
The invention defined in claim 2 in which said motive means comprises a motor having a rotating output element and in which said mass comprises a weight mounted on said rotating element with its center of mass displaced from the axis of rotation of said rotating element.
Claim 5
Dependent Claim
22 words
The invention defined in claim 3 in which both motor and mass are mounted together at said one end of said spring.
Claim 6
Dependent Claim
52 words
The invention defined in claim 4 which further comprises a housing in which said motor and mass are housed; and means for rotating said motor at a rotational frequency corresponding substantially to an integral multiple of the resonant frequency of said spring and the combined mass of said housing and said motor.
Claim 7
Dependent Claim
19 words
The invention defined in claim 5 which further comprises means for adjusting the frequency of rotation of said mass.
Claim 8
Dependent Claim
61 words
The invention defined in claim 5 in which the cantilever spring is effective in relaxed condition to hold the holder such that its central axis is substantially parallel with the central axis of said cantilever spring and to hold said housing such that the axis of rotation of said mass extends obliquely at an angle from said axis of said spring.
Claim 9
Dependent Claim
47 words
The invention defined in claim 7 in which said housing is formed with a wall, at the side away from said holder, which extends in a direction parallel to the axis of rotation of said mass whereby vibratory action occurs in a direction perpendicular to said wall.
