S. E. FOLLESE MASSAGE DEVICE Aug. 3, 1937.
Filed Oct. 9, 1956 Patented Aug. 3, 1937 UNIT-ED STATES MASSAGE DEVICE n Sigurd E. Follese, Minneapolis, Minn.
Application October 9,
My invention lprovides an improved massage device and, generally stated, consists of the novel devices and combinations of devices hereinafter described and defined in the claims.
This device involves the `use of a vacuumcup connected to a source of partial vacuum or suction, and within said vacuum' cup a patter head or plate that is arranged to be vibrated against the surface of the flesh to Vwhich the cup is' applied and to produce apatting or tapping action while the partial vacuum or suction is applied. The vacuum cup,` at least in part, is of a flexible material, such as quite soft rubber, and the patter head is faced witha soft material, such as sponge rubber. The partial vacuum or suction maintained in the cup may be produced in various different ways, as by connection to the vacuum tank,avacuum pump, or to the suction-acting discharge of a stream of water running from a faucet. The vibration or reciprocation Aof the `patter head is preferably produced from a small electric motor, the rotor shaft of which is provided with an out-of-balance'or eccentrically offset weight, the vibratory action of which is transmitted to the patter head through a plunger or stem connected to the head, arranged vto reciprocate through a bearing in the cup, and connected to the motor casing.
The important and improved actions of this type of a device will hereinafter appear.
While capable of more general use, vthe massage device has been primarily intended for use on bald or nearly hairless 'heads tore-establish normal circulation of the blood and to promote the growth of the hair.
A commercial form ofthe deviceis illustrated in the accompanying drawing, wherein like characters indicate like parts throughout the several views.
Referring to the drawing:
Fig. 1 is a side elevation, with some parts broken away and some parts sectioned, showing the improved device;
Fig. 2 is a view chiey in section on the irregular line 2-2 of Fig. 1, with some parts shown in full; and
Fig. 3 is a fragmentary detail in section approximately on the line 3-3 of Fig. 2.
The vacuum cup 4 is of quite soft rubber, the rim of which is` very flexible, but the body portion of which is partly encased in a pressed sheet metal casing 5. At the axis of the cup is a tubular sleeve 6 headed at its cuter end and provided at its threaded inner end with a clamping nut 'I and whereby the back ofthe cup and the casing 5 are `1936, Serial N0. 104,823
(Cl. 12S-53) rigidly secured together. The sleeve-6 affords a bearing for an axially disposed plunger 8, the inner end of which is rigidly but detachably secured to the hub of a metallic patterhead or disc-like plate 9 that is faced with a soft and ,f5 pliable elastic material, such as sponge rubber ID. At its Vouter end the plunger 8 is rigidly securedto the axially projecting shank I I-of a hollow crank casing I2. This crank casing I2, in the `preferred structure illustrated, is rigidly butV detachably sef-` d0 cured by screw-threaded devices `I3 to `one end of the casing I4 of an electric motor, `the rotor `shaft I5 of which projects into the casing I2 andis provided with a crank-acting element in the form of a radially oiTset Weight I6. The current Acan l5 be supplied to the motor by any suitable means, such as lead wires Il, shown only in Fig. 1.
The device is adapted to be held in several different ways, but to adapt the same to `be heldand pressed against the head of the person operating :.20 `the same, the shank I I is shown as provided with oiset arms or hand grips I8. l
A coiled spring I9 is placed around the plunger 8 and compressed between the shank IVI and the head of the sleeve 6. This spring tends to keep 25 the tapper head 9 retracted within the vacuum cup and the vacuum cup pressed away from the shank as far as permitted by engagement of the hub of head 9 with the inner end of sleeve 6. As a means for applying suction or partial `30 vacuum to the interior of the vacuum cup 4, the latter is shown as provided with a nipple 20 that is extended through the wall of said cup and ,through the casing 5 and is clamped thereto by a nut 2I having threaded engagement with the in- 35 ner end of said nipple. The outer end of the nipple is connected to a rotor or other ilexible tube 2-2 which, in practice, will be connected to a source of vacuum or suction, such as those already enumerated.
To limit the degree of partial vacuum applied to the interior of the cup, it is provided with an inwardly opening relief valve 23. The head of this relief valve is normally seated against the inner end of the valve seating sleeve 24 that is 45 extended through a wall of the cup and casing 5 and is clamped thereto by a nut 25 having threaded engagement with the outer end of said valve sleeve. At its outer end the stem of the valve 23 is provided with a rigidly secured head 26. 50 A coiled spring 21 is placed around the outer end portion of the stem of the valve 23 and is compressed between the nut 25 and an adjusting collar 28, which latter has threaded engagement with the stem of said valve and aiords means 55 for adjustment to vary the degree of partial vacuum or suction required to open said relief valve and permit air to flow into the vacuum cup.
The action of the device described is substantially as follows: When the electric motor is in action the crank-acting weight I6 will produce vibration of the entire casing and of the plunger 8 and patter head 9. When the rim of the cup 4 is pressed tightly into engagement with the flesh, which we assumed to be the bald surface of the head, partial vacuum or suction will be pro'- duced in the cup and this will draw ther blood from the arteries into the Zone covered by the cup. If the electric motor is then started in action and the plunger is pressed so as to bring the soft faced end of the head 9 into Contact with the flesh, this latter action will produce a rapid, mild, but very effective tapping action on; the flesh. 'I'his tapping action, of course, is produced while the partial vacuum is maintained.
In practice it seems to have been effectively demonstrated that the vacuum draws the blood up through thearterial circulatory System and holds it there, while the vibratory patting or pressure is produced; and that this tapping action ,produced under vacuum pressure forces the blood cute-through the venoussystem, thereby establishing, that complete lcirculation through the scalp, thai-.lis essential to. the growth of hair. Also, A it`l` isv found that the vibratory pressure breaks down the hardened `tissues of the skin and permits expansion ofthe capillaries to their norvmal size ormcondition necessary to normal circulation and normal growthof hair.
From the foregoing, it will be evident that the 'device disclosed, and the preferred form of which is illustrated in the drawing, is capable of Various modifications Within the scope ofthe invention herein disclosed and sought tof be claimed.
