STEWART MASSAGE TABLE 4 Sheets-Sheet 4 Filed June 10, 1957 IL ow [L ATT OR N EY Unit S The present invention relates to method of massage as 'well as improvements in table apparatus on which a human body may sit or recline and be subject to mechanical vibrations. Such tables are well known in the art and they have gone into limited use particularly in connection with physical therapy.

It is the main object of the present invention to provide a table of the class described in which improvements have been made in the arrangement, construction and operation of the vibrating means and in the areas of vibration so as to simulate the effects of Swedish massage.

Another object is to provide an apparatus of the type described in which the supporting surface of the table is subjected to selective and localized areas of vibration.

Another object of the invention is to provide an apparatus of the type described in which there is a plurality of sources of vibration, said sources having both general and localized vibrational effects upon the body supporting surface of the table, the frequency and amplitude of the vibration of each source being selectively controlled.

' A further object is to provide a vibratory table for simulating Swedish massage characterized by surges or out-of-phase vibrations which (a) impart a rippling action to the muscles of the body, (11) provide a gentle manipulation of the joints, and subject the areas of the body engaging the table surface with a gentle hacking or pounding motion.

'A still further object of the invention resides in a meth 0d of simulating Swedish massage by imposing vibrations to produce surges and out-of-phase conditions upon a vibratory table surface.

' A still further object is to provide an improved method of simulating Swedish massage in which a resiliently supported surface vibrates at one frequency and as locali'zed areas within the same surface vibrating at a different and variable frequency. v v

I Another object of the invention is to provide a method of simulating Swedish massage comprising steps of impressing a vibration of higher frequency lower amplitude upon a body supporting surface having an existing vibration of lower frequency higher amplitude.

A still further object is to provide a method of subjecting a human body to vibrations simulating Swedish.

massage comprising the steps of supporting the body upon a surface having a consistency comparable to human flesh and vibrating the support at out-of-phasefrequencies to provide surges of impressed vibrations to the body supporting surface.

These and other objects and advantages of the invention will appear from the following specification and claims.

Referring to the illustrated form of the invention, the

table 10 is shown with a head end 12, a foot end 14, supporting legs 16, and a top supporting massage surface 18. The rigid vertical sides and ends 20 give marginal support to the pad 22. A control panel 24 is shown attached to one side 20.

In practice, the table 10 is approximately seven feet in length to permit an adult person of normal height to comfortably recline upon the pad with the width approximately three feet to support the body well within the sides 20. A main vibrating frame 26 which in the illustrated and above described form may be roughly two feet by six feet, is of relatively rigid structure. 'As shown the sides 28 of the frame 26 are of inverted U section with L-section ends 30.

Sides 20 may be of plywood to which longitudinally extending L-section rails 32 are attached to give support to the springs 34 which in turn give support to the sides 28 of the frame 26. As shown, springs 34 are coiled with a lower horizontal projection 36 having an eye to receive a suitable fastener for securing the springs 34 to the rails 32. The remainder of the springs 34 are shown coiled about a vertical axis with an eye at' the upper end to receive a suitable fastener for the attachment of the upper ends of each spring 34 to the sides 28. Space blocks 38 are shown inserted into the channels of the sides 28 at the location of each spring 34. Parallel to the ends 30 are spaced inverted T-section cross members 40, 42 and 44 attached at their outer ends to the sides 28. The L-section cross members 45, parallel to the sides 28, and extending between the end 30 and member 40 and between the member 40 and the member 42, complete the main vibrating frame 26."

The massage. characteristics. of the pad 22 may be further regulatedand altered. with the switch 66..onand the knob 90-at station-No. l. frame26 being-generally vibratedby the motor '50 '(No.'

In .each ofstations 1 to 1.1. itzwillhbe understood that. themotors No.-.1 to No. 11 inclusive, may have their speed ofirotation, and the .resulting frequency of amplitudeof-vibration varied by manipulating This will result in; the

l of Fig. at one selected frequency anda portion of the superstructure of the frame 26 being independently vibrated at the same or different frequency with any one or more of the switches 72, '76, 80 or 84 in on position. With this arrangement it becomes possible to impress one frequency and amplitude of vibration of the pad 22 upon another frequency and amplitude of vibration.

. It will be understood that from the layout of the control panel of Fig. 7 and from the wiring diagram of Fig. 10 that with the switch 66 off any one or all of the motors No. 2, 4, 5, 7 and 8 may be independently and variably operated either alone or in desired combinations. With the switch 66 on, any one of the motors Nos. 1, 2, 3, 6, 9, 10 and 11 may be operated by manipulating the knob 90 simultaneously with all or any one or more of the motors Nos. 4, 5, 7 and 8. While it has been found necessary in practice, if desired, the individual control provided for the motors 4, 5, 7 and 8 may be extended to include any one or more of the remaining motors.

In practice, it may be desired to massage the feet or thoracic region with high frequency, low amplitude vibration while at the same time subjecting the hip area to surges of lower frequency, high amplitude. This can be accomplished (l) with the switch 66 on and the knob 90 at either station 10 or 11 and the rheostat 68 adjusted for high motor speed and (2) with the switches 72 and 7-6 on and the rheostats 74 and 78 adjusted to give the desired frequency, amplitude and surge conditions. Moreover, other combinations and arrangements for massaging different parts of the body at the same time under different conditions will readily occur to those skilled'in the art of massage and physical therapy.
