Abstract
Abstract Method and apparatus are disclosed for massaging and otherwise treating the hands, more specifically the nails and cuticles. A uniquely contoured hollow handrest of shell-like configuration which comfortably supports either hand with the fingers in outstretched, separate positions, is centered in a shallow container of treating oil. The inner periphery of the container includes a semi-annular barrier of oil-soaked sponge against which the fingernails and cuticles rest, and means for heating the oil above room temperature. The handrest is constructed to include a vibrator adjacent to its inner surface. Thus, the fingers and nails of a hand under treatment may be simultaneously soaked in hot oil and massaged with vibrations.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
270 words
An apparatus for hand treatment which comprises in combination: A shallow container constructed to hold a quantity of treating oil therein and having a top edge surface, a bottom surface and peripheral wall surfaces having a central opening therein; A handrest, said handrest being formed of substantially rigid material contoured in a convex curvature on its upper side, and substantially hollow on its underside, said convex curvature shaped to accomodate a hand for treatment with the fingers in outstretched separated positions so that the palm rests near the zenith of said curvature and the fingers depend against the sides with their respective ends near the lower periphery of said handrest; said handrest being disposed in said central opening, the inner peripheral wall of said container being spread-apart from the outer periphery of said handrest and forming a semi-annular gap therebetween and said zenith of said curvature extending above said top surface; a strip of sponge disposed in said gap to at least partially surround said inner peripheral wall of said container and being slightly spaced apart from the outer periphery of said handrest to accomodate the ends of the fingers of said treated hand in contact with said sponge; means comprising an electrical heater disposed in heat transfer relation to said container for heating said oil to a temperature above room temperature; vibrator means coupled to the hollow underside of said handrest and constructed to impose a vibratory motion on said handrest; and electrical circuit means connectable in energy transfer relation between said heater and said vibrator means and a source of power for energizing said heater and said vibrator.
Claim 2
Independent Claim
270 words
An apparatus for hand treatment which comprises in combination: A shallow container constructed to hold a quantity of treating oil therein and having a top edge surface, a bottom surface and peripheral wall surfaces having a central opening therein; A handrest, said handrest being formed of substantially rigid material contoured in a convex curvature on its upper side, and substantially hollow on its underside, said convex curvature shaped to accomodate a hand for treatment with the fingers in outstretched separated positions so that the palm rests near the zenith of said curvature and the fingers depend against the sides with their respective ends near the lower periphery of said handrest; said handrest being disposed in said central opening, the inner peripheral wall of said container being spread-apart from the outer periphery of said handrest and forming a semi-annular gap therebetween and said zenith of said curvature extending above said top surface; a strip of sponge disposed in said gap to at least partially surround said inner peripheral wall of said container and being slightly spaced apart from the outer periphery of said handrest to accomodate the ends of the fingers of said treated hand in contact with said sponge; means comprising an electrical heater disposed in heat transfer relation to said container for heating said oil to a temperature above room temperature; vibrator means coupled to the hollow underside of said handrest and constructed to impose a vibratory motion on said handrest; and electrical circuit means connectable in energy transfer relation between said heater and said vibrator means and a source of power for energizing said heater and said vibrator.
Claim 3
Dependent Claim
18 words
The combination in accordance with claim 1 wherein said handrest comprises a substantially rigid thermoplastic or like material.
Claim 4
Dependent Claim
51 words
The combination in accordance with claim 1 wherein the surface of said handrest is substantially smooth near the zenith of said curvature, the lateral surface thereof being formed to include a series of elongated downwardly extended grooves having inwardly curved cross-sections to accommodate the thumb and fingers of the treated hand.
Claim 5
Dependent Claim
78 words
The combination in accordance with claim 3 wherein said elongated downwardly extending grooves include a pair of grooves, each of a width to accommodate the outstretched thumbs of a hand under treatment, the grooves of said pair being directed toward the front of said handrest in substantially equal and opposite directions from its principal axis of symmetry, and a plurality of narrower grooves therebetween, each of a width to accommodate the outstretched fingers of a hand under treatment.
Claim 6
Dependent Claim
39 words
The combination in accordance with claim 1 wherein said electrical heater comprises insulated wire having a resistivity of the order of 100 ohm-centimeters at 20 degrees centigrade, disposed adjacent to a portion of the inner periphery of said container.
Claim 7
Dependent Claim
77 words
The combination in accordance with claim 1 wherein said vibrator means includes in cooperating relation: an electromagnet connected to be energized by said electrical circuit means when connected to a source of power: a ferromagnetic spring-biased arm rigidly connected at one of its ends to the underside of said handrest; said spring-biased ferromagnetic arm, responsive to energization of said electromagnet, being alternately attracted and repulsed as the alternating current reverses phase thereby imposing vibrations on said handrest.
Claim 8
Dependent Claim
31 words
The combination in accordance with claim 6 wherein said vibrator means includes adjustment means coupled between the underside of said handrest and the ferromagnetic arm for controlling intensity of said vibrations.
Claim 9
Dependent Claim
45 words
The combination in accordance with claim 1 wherein said container is filled at least about half full of treating oil warmed to a temperature within the range 100 to 120 degrees Fahrenheit; and wherein said sponge is at least partially immersed in said warmed oil.
Claim 10
Independent Claim
90 words
The method of therapeutically and/or cosmetically treating the hands which comprises the steps of: placing the hand under treatment on a handrest contoured to hold the thumb and fingers in outstretched relation; resting the tips of said fingers, including the nails and cuticles, against a strip of sponge; immersing said fingertips and said sponge in a therapeutic oil bath maintained at a temperature within the range 100 to 120 degrees Fahrenheit; and simultaneously imposing on said handrest vibrations at a frequency within the range 50 to 60 cycles per second.
Claim 11
Independent Claim
