Abstract
Abstract A head massaging machine consisting of a hollow double-walled helmet having a rotary inner shell member formed with sinusoidal cam channels. Resiliently mounted in the inner wall of the helmet are inwardly projecting resilient head-massaging fingers provided with rigid follower pins engaged in the cam channels. A motor mounted in the helmet rotates the shell member, causing the massaging fingers to oscillate, to thereby provide the headmassaging action.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
91 words
A head-massaging apparatus comprising a helmet, a plurality of inwardly extending massaging projections movably mounted on the interior surface of the helmet, a motor in the helmet, and means drivingly coupling said motor to said massaging projections, wherein said helmet is hollow and has an outer wall and an inner wall, said projections being movably mounted in said inner wall, and wherein the projections are resiliently mounted and the means drivingly coupling the motor to said projections comprises a rotary cam member connected to said motor and drivingly engaging said projections.
Claim 2
Dependent Claim
91 words
A head-massaging apparatus comprising a helmet, a plurality of inwardly extending massaging projections movably mounted on the interior surface of the helmet, a motor in the helmet, and means drivingly coupling said motor to said massaging projections, wherein said helmet is hollow and has an outer wall and an inner wall, said projections being movably mounted in said inner wall, and wherein the projections are resiliently mounted and the means drivingly coupling the motor to said projections comprises a rotary cam member connected to said motor and drivingly engaging said projections.
Claim 3
Dependent Claim
91 words
A head-massaging apparatus comprising a helmet, a plurality of inwardly extending massaging projections movably mounted on the interior surface of the helmet, a motor in the helmet, and means drivingly coupling said motor to said massaging projections, wherein said helmet is hollow and has an outer wall and an inner wall, said projections being movably mounted in said inner wall, and wherein the projections are resiliently mounted and the means drivingly coupling the motor to said projections comprises a rotary cam member connected to said motor and drivingly engaging said projections.
Claim 4
Dependent Claim
91 words
A head-massaging apparatus comprising a helmet, a plurality of inwardly extending massaging projections movably mounted on the interior surface of the helmet, a motor in the helmet, and means drivingly coupling said motor to said massaging projections, wherein said helmet is hollow and has an outer wall and an inner wall, said projections being movably mounted in said inner wall, and wherein the projections are resiliently mounted and the means drivingly coupling the motor to said projections comprises a rotary cam member connected to said motor and drivingly engaging said projections.
Claim 5
Dependent Claim
38 words
The head-massaging apparatus of claim 1, and wherein said cam member comprises a shell element located between said outer and inner wall and having cam channel elements, said projections having follower members engaged in said cam channel elements.
Claim 6
Dependent Claim
28 words
The head-massaging apparatus of claim 2, and wherein said cam channel elements are substantially sinsusoidally curved, whereby to oscillate the projections responsive to movement of the shell element.
Claim 7
Dependent Claim
32 words
The head-massaging apparatus of claim 3, and wherein said shell element is of substantially spherical curvature and said cam channel elements are formed on base circles substantially coaxial with said shell element.
Claim 8
Dependent Claim
43 words
The head-massaging apparatus of claim 4, and wherein said projections comprise finger-like bodies of resilient material secured in said inner wall, said follower members comprising relatively rod-like members embedded in the inside ends of said projections and extending into said cam channel elements.
Claim 9
Dependent Claim
38 words
The head-massaging apparatus of claim 5, and wherein a plurality of spaced rollers are journaled between the peripheral marginal portions of said outer and inner walls, and wherein the rim of said shell element supportingly engages said rollers.
Claim 10
Dependent Claim
21 words
The head-massaging apparatus of claim 6, and wherein said projections are arranged in staggered concentric circular rows on said inner wall.
