lustrating the relation of an, applicator, shown by dotted lines; to an attaching means;

Referring to the drawings, the body portion lot the housing is preferably in the form of a box-like casting adapted to receive the cover2. In this housing I mount a motor shown conventionally at 3. The motorshaft 471's provided witha pulley 5;; 1 p 7 "EDisposedin parallel relation to the motor shaft lis adriven shaft Gsupported in bearings' 7 mounted i within] the body portion of 'the housingon suitable blocks or pedestals 8. The: housing has opposed openings 9 in its 7 side-{walls adapted to receive the crank "disks, 10. w

' Thi shaft a I 11 features alined with the pulleys 5 on the motor shaftand connectedthereto by means of the belt.

12 of or triangular cross section. The: crank disks 10 are provided with radial dovetailed slots 1 3 adapted to receive the heads l lof thegthreaded' studs 15, the heads of these studsbeing, slidable in grooves.

' The body members 16 of the crank pins are threaded upon these studs to clamp them in their adjusted position. These crank pin body members are chambered at 17 to receive supporting bearings for the applicator k attaching studs 18; These bearings in the. Th1r.d,-'to provide animproved massaging F embodiment illustrated consist of the annular; bearing members 19 secured to the body members, the inner bearing members? 20 secured to the studs and the coacting balls 21. The bearing members 20 areretalned upon the studs by; means of the washer-like'plates 22' held in place bythe screws 23. I 7

A lubricant retaining ring 24; is provided toclose the space between the bearing mem bers l9 and 20 and. alsoa closure plate 25 which is secured on a shoulder 26'within the recess ofthe body memberby means of the screws-27 so that, while the studs project from the body members, the chambers are efiectively sealed to retain lubricant. v

7 The studs have annular grooves 28 therein to receivethe eyes 29 of the spirally curved applicator attaching members 30, these eyes being formed one end of the attaching members as is illustrated. The applicators as 3lmay he-engaged with these spirally formed hooks. The eyes have. a friction engagement with the studs sothat while they are normally fixed thereto,the hooks may in the event of undue stress rotate relative to the studs.

w With the parts thus arranged the studs turn freely relative tothe' crank pins so that they may swing to any position and the hooks I swing to Whatever-direction of pull there maybe on the applicators.

.' Further. in the event'of the applicators, 05

ends'jof the hooks. This arrangement also has a an advantage mas the whipping action due to the direct connection of the applicator with the crank pin is minimized.

I have, illustrated and described my: im-

or embodiments which I contemplate as it is i. believed that this disclosure -Wil1 enable those skilled in the a'rtto: embody or adapt the same as maybe desired. a

I claim as new and desire to secure by Letters Patent is; I;
