A further and impo rtant1 object isY tolprovide a massaging machine Whichwill beneficially, exercise the vertebrae withoutjarring or other harmrful or detrimental effects.

The principal featureof the invention-:Consists .in providing a roller .tablecomprising positively driven endless. series ofceccentrically, journalled e .rollers adaptedI to rotate With-an eccentric motion under thevveight of apatient and. provided with 4central groovesto receive thespinalcolurnnand prevent jarring of same.

A further. important featurerconsists irlarranging a positively rotatedv drum at thehead ofthe table andV mounting a plurality;of -.eccentrically journalled rollers around l the.periphery.; of the 4drum to vmassage theneck of the. patient.

A kfurther andA important feature. consists in arranging asplurality. of largeeccentrically jour- `nalled rollers beneath `the .upper-.reach ofthe. endless series offrollersto form a supportingsurface for same-providing a riseandfall-ofthe roller table in accordance `with .the .rotation of the enlarged rollers. i

A still further featureA consists in providing at least some of the endless series of rollers of .differyent size than the adjacent rollersand at least ysome as non-rotating rollers to provide aeglide stroke in the massaging action. i

A still further, feature .consists .in providing some of theeccentric rollers With diierenteccen- `of the muscles of the 'backA the nerves "and blood vessels associatedwith the nerves and feeding the spinal cord become pinched producing harmful eiects and reducing circulation .lf Normal physical exercise will not counteract this naturalcontraction of the muscles Ywhich vrequire y.exercising at frequent intervals to retain them irfila relaxed healthful condition. l

I have found through careful experiment that 2 my machineeproduces the, desired kneading and n to thoroughly relaxrandloosen y theJniuscles. easing crampednervesfand asso- V l ciated .hloodjvessels'and permitting: materially inations- I' have else. foundehat my machine enables the exercising.

' Extending between the Walls of the casing at 50 theh'e'ad ofthe machine'i's a s haft l8 which is Mounted on the 'shafty i8 is a drum "2l having 'nach o f the drums 1 -is formes wn-.n enlarged 3 a plurality of rollers 23 of a size smaller than the rollers 5 eccentrically journalled around the periphery of its end flanges 24.

It will be noted that the drum 2| and rollers 23 carried thereby extend somewhat-faboveethe upper reach of the endless series of rollers 5 and in the normal operation of theinach'inethe patient is placed on the upper reach of the rollers 5 with his neck resting on theroll'ers 23.

In the operation of my machine the patient lies on the roller table as formed by theupper reach of the endlessrollers 5 with his neck on I 'the'.ro'llers' as described-and with-'the'fro'llers '5 extending to adjacent ythe base of his spine or jooccyx and withhis legs extending overthe edge ofthe machine orpreferablyiwith hisknees'vdrawn up and-his feet'pla'ced on the platform 25; asprovided bythe casing 2.

The weight of the patients torso is 'thus :acting to depress'the'upper reach of the-rollers 5 'and to force same downwardly to contact the enlargedrollers I'l arranged beneath'the-belts 3.

` With 'the motor i2 operating thedrums vvI are positivelyrotated through the V'belts I'I-*and the flat belts 3 are operated in th'direct-ion of--the arrow.

Therollers 5'and'thel enlarged rollers Il rotate under the'weight of 'thel patient-with-the 'eccentricity of the rollers 5 'acting to knead and-massagethe muscles or the back as they move beneath the patient,"whi1e the enlarged'rollers Il amplifytlie effects of'thesmaller rollers and also cause a tilt of'sections of the roller table'and a subsequent fall of theroller table to exercise the vertebrae. n Thus all'thein'uscles of the` back arebeing kneaded and exercised gently yet eciently while the backbone," which lies in the circumferential central groove 'i of thero'llers is'pr'even'ted vfrom jarring'. Similarly the muscles adjacent'the base of the skull or in"the"neck"are being 'exercised by the rotation of thedrum 2'! "carrying-'the'rolters 23, which'again, due to theireccentri'cmovement, 'effect massaging and' kneading' action.

'With the provisions of the' iixedv` ribs 8'sp'a'ced at intervals between the rollers ap'eriodic gliding stroke down the patients back is provided and thisaction 'has been found to materially increase the kneading and flexing of the muscles.

A further 'beneflcia1..motion is obtained'with the rollers 9 'which'have*differenteccentricities at opposite ends. These rollers `ll'are preferably larger than the rollers 5 'and' provide av pronounced lateraltilt and fall to thetable asthey'prog'ress under the patients back.

With the various l arrangements of 'eccentric rollers described the musclesare `subjected to a thorough kneadin'g and flexing and become loose and'pli'able in an'extremely short time; allowing free circulation and releasing pinched o'r impinged nerves, alleviating harmful and often painful conditions of the back and beneficially exercising the arrar-igements` oieccentric rollers may :befprovided without departing from the scope of my invention as set forth the .appended claims.
