`Applieatian'filed November My invention is for an improvement. in

An object of my invention. is to provide a bank or row of machines which maybe operated by a common drive shaft. lThis will allow several persons'to be served by a single driving medium. Another object is to mount the drums of the machines eccentrically of the drive shaft so that anjoscillatory as well as a rubbing pressure with vmotion action is produced. A further object is to provide means` for producing a kneading action during the massaging caused by the rotating drum, which will be' similar to that accomplished by rubbing with the hands. A still further object is to attain the variation in pressure which is accomplished bya trained masseur.

Il accomplish these' objects by the .device illustrated in the in whichy y v vFigure 1 is an elevation partly in section accompanying drawings,

of the bank or row of,machines and they motor attachment, A

Figure 2 is a cross section on line 2-2 of Figure l,

Figurev 3 is a detail view, Figure l is an elevation of a form of roller. y y

Similar characters of reference referto similar parts thruout the several views.

rllhe machines, 5 are mounted on a common drive shaft 1. On keither side of each machine is an invertedU shaped support 2 including posts and cross bars which serve a double function, nainelyras a mounting for the machines and also as ahand fgrip of which more will appear` intra. across each of the pairs oflegs of the support members 2, 2 is a bar 3, 3 having journals 8, 8, therein, thru which is mounted the modified i drive lshaft 1.

At one end of this shaft is'a trainv of gearing 11 which connects the said shaft to an operating means at which is preferably an electric motor. y

As .all of the massage machines of the bank are similar, a detailed description ofy but onewill be given. However it is to vbe noted that the body contact members or rollers may vary 'as to their surface struc-- 7, 7. yThe plates are fixed to the shaft 1 ,toy

It is apparent that the drum may be straddled to massage the inside of the legs, or limb mayv ne placed acrossv the drum, or the Vtorso held T' ithereagainst.. As the drum rotates, due to y its eccentric Inountingit. will gradually press against the part` offered thereto, in-

pressure thus completing a'cycle.V Upon con-A creasing the pressure as it rotates ,and` will 'then upon continued' rotation,relieve"`the` tact. of the part to. be massaged with the drum, lthe loosely mountedv rollers will be rotated. These rollers are also eccentrically mounted so that a kneading action will occuras lthey rotate and pass fered to the drum will be rubbed and kneaded simultaneously. The pressure exerted by the drum will be controlled bythe person operated upon, ldepending upon the weight so i p over the part offered. The result will be vthat the part of of the body and the force exerted by said person against the hand grips. ,Y v l A modified form of roller 12 is shown in drum by means Iof the,
