out-of-phase vibrations which (a) impart a rippling
action to the muscles of the body, (b) provide a gentle
manipulation of the joints, and (0) 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
method of simulating Swedish massage by imposing vi
brations 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
shown coiled about a vertical axis with an eye at the
upper end to receive a suitable fastener for the attach
ment 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. Par
allel to the ends 30 are spaced inverted T-section cross
members 40, 142 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 marginal support of the pad 22 by the sides and
end 20 is supplemented by a plurality of planar mem
bers 46, 46' which are shown of rectangular shape but
different and variable frequency.
Another object of the invention is to provide a method 50 of varying area. The location, number and area of the
members 46 depends upon the area of support and selec
