The housing 27 is attached to the inner wall 4a by means of four bolts 29 (typical) and said housing 27 is held in place at the'outer wall 40 by cover plate 30.

Referring now'to FIG. 3 there is shown the method for removing brush 1 from socket means 3a. To remove brush 1, said brush is pressed axially outwardly in the direction of socket means 3a; the shaft 2 forces partial spherically-shaped cup 18 outwardly thereby compressing spring 28. In this manner the opposite end of shaft 2 is drawn inwardly clearing the outer face of cover plate 31. The entire brush 1 and shaft crosssectional is then rotated upwardly and the end of shaft 2 withdrawn from partial spherically-shaped cup 18.

Referring to FIGS. 4, 5 and 6, there is shown another embodiment of the invention. Brush 101, similar in construction to aforesaid brush 1, is housed within bathtub 104, tranversely disposed between inner walls 104a and 104b and outer walls 1040 and 104d, respectively. Said cylindrical brush is mounted on axially rotatable shaft 102 so that said brush rotates with said shaft. The shaft 102 desireably has a square crossectional configuration.

The end of the shaft 102a, opposing wall 104b, is slidably received in the inner surface of an inner annular collar 103, the outer surface of said collar is grooved to receive ball bearings 105 (typical). And surrounding the ball bearings is an outer annular collar 106 with a groove on the inner surface of the outer annular collar 106 so as to retain the ball bearing therein. This ball bearing assembly is similar to other assemblies in this embodiment as well as other embodiments as will be pointed out hereinafter.

Fixedly attached to the outer surface of outer annular collar 106 is the lower end of a first vertical member 107 which is perpendicular dispoed to shaft 102. The upper end of vertical member 107 is fixed attached to the outer surface of an outer annular collar 108 of a ball bearing assembly similar to the previously described ball bearing assembly; the components being an outer annular collar 108, ball bearings 110 (typical), and inner annular collar 109.

Slidably retained within the central hole of inner annular collar 109 is one end 1 11a of a support shaft 111, said support shaft being in parallel disposition to aforesaid brush shaft 102. The other end lllb of said support shaft 111 is centrally mounted at one end of motor M.

At the other end of motor M is a drive shaft 112 which is in parallel disposition with brush shaft 102, said drive shaft 112 the axis thereof being coincident with the axis of support shaft 111. Mounted on said drive shaft 112, between the end 112a thereof and motor M is a third ball bearing assembly similar to the aforesaid assemblies; having an outer annular collar 113, inner annular collar 114 and ball bearing 115 (typical). Fixedly attached to the outer surface of outer annular collar 113 is a depending second vertical member 116 which is in parallel disposition with aforesaid first vertical member 107. The lower end of vertical member 107 is fixedly attached to a fourth ball bearing assembly, similar to the aforesaid ball bearing assemblies and having outer annular collar 117, inner annular collar 118 and ball bearing 119 (typical).

Mounted within inner annular collar 118 is a rotatable connecting shaft 120 having on the inward end thereof a cup 121, the inner periphery of cup 121 slidably receives one end 102b of square brush shaft 102.

Mounted within the interior of cup 121 is a spring 122 for urging the shaft 102 inwardly so that the other end 102a of the shaft presses against retaining plate 123; mounted said plate 123 within the inner bore of inner annular collar 103.

Thusly, the brush 101 is in parallel disposition to shafts 111 and 112 and joined thereto through vertical members 116 and 107, respectively, and through the aforesaid four ball bearing assemblies. By this construction the brush may be manually positioned along an arcuate path, the radius of the arch being the length of the vertical members. In this manner the brush may be positioned by a person lying in the bathtub to several heights in the bathtub as is desired.

Referring again to FIG. 5, there is shown the end 112a of drive shaft 112 which shaft rotates with actuation of motor M. Mounted near the shaft end 112a is an upper pulley 124 having retained on the inner periphery of a central bore therein, an annular ring 125, said ring 125 frictionally held to drive shaft 112. The peripheral groove of upper pulley 124 frictionally receives endless belt 126.

Referring again to FIG. 5 and more specifically to FIG. 6, there is shown the lower pulley 127, similarly constructed to the upper pulley 124, and having an inner annular ring 128, said ring frictionally receiving the aforesaid connecting shaft 120. The peripheral groove of the lower pulley frictionally receives the aforesaid endless belt 126 in a manner similar to that as afore-described for the upper pulley 124.

By this manner of construction, the actuated motor M rotates drive shaft 112 causing rotation of upper pulley 124 thereby moving endless belt 126 which in turn translates its movement to lower pulley 127 which in turn causes rotation of connecting shaft 120 which in turn rotates shaft 102 thereby rotating cylindrical brush 101.

The top side walls 104s and 104fof bathtub 104 are provided with guide channels e, and 150f, respectively. The guide channels are pressedly held between walls W1 and W2 by turnbuckle means 151e and 151f, respectively. Rotatably housed within said channels 150a and l50fare two sets of roller-mounted parallel, spaced, support bars 152 and 153 said bars in parallel disposition to shaft 111, 112 and brush shaft 102; bar 152 having rollers 152a and 152b freely rotatable at the ends thereof, and bar 153 having rollers 153a and 153b freely rotatable at the ends thereof. The bars 152 and 153 per se do not rotate, but rotational bearing surfaces 154 (typical) at the ends thereof permit free rotation of the rollers 152a, 152b, 153a and 153b. The rollers upon rotation roll through and within aforesaid guide channels.

The support bars 152 and 153 are interconnectedly spaced by means of members 155 and 156; each of said members being affixed to one of said support bars. Member 156 is in the shape of a platform, and as such, serves as a platform for motor M which is mounted thereto.

By means of the construction described immediately hereinabove, a person lying in the bathtub can move the cylindrical brush 101 laterally, as shown by the double arrow in FIG. 4.

In operation, a person lying in the bathtub can adjust the cylindrical brush to any height at any lateral point in the bathtub, thereby permitting numberous positions in which the rotating cylindrical brush can contact any one of several parts of the body. For example, the legs may be positioned under the brush or draped over the brush. Also, the person in the bathtub may assume several postures, such as lying on the back, prostrate, or sitting, as desired, for brush massaging.

Referring now to FIGS. 7, 8 and 9, there is shown still another embodiment of this invention. In FIGS. 7 and 8 there is shown a cylindrical brush 201, similar to aforesaid brushes 1 and 101, transversely disposed in bathtub 204. v

The drive means for rotating cylindrical brush 201 comprises a motor M-l, mounted below floor F and mounted outwardly of and below the outer wall 204a, by means of vertical plate P. The motor drive shaft 202 protrudes inwardly through outer wall 204a and outwardly of the outer surface of the corresponding inner wall 204b. Mounted at the end of drive shaft 202 is, lower pulley 205 having endless belt 206 frictionally held to the peripheral groove therein. Rewardly and upwardly of the lower pulley 205 is an upper pulley 207 of larger diameter than the lower pulley 205.

Endless belt 206 is of course frictionally and tautly held to the peripheral grooves of the lower and upper pulleys so as to translate motion therebetween. Both of the aforesaid pulleys are disposed between the outer surface of inner wall and the opposed inner surface of outer wall 204a of the bathtub 204.

Projecting inwardly from the hub of upper pulley 207 is a rotatable cylindrical connecting shaft 208 having an axial square hole 208a therethrough. The connecting shaft protrudes through the inner wall 204b into the bathtub cavity and is rotatable within bushing 209, said bushing mounted in the inner wall and retained therein by cover plate 210, said cover plate fixed mounted to the inner surface of the inner wall 204. The cover plate has a central bore 210a through which connecting shaft 208 slidably passes, thereby allowing the connecting shaft to freely rotate therein.

The square hole 208a of connecting shaft 208 slidably receives one end 211a of square brush shaft 211 being fixedly fitted into a central bore 201a at one end of cylinder 201b of brush 201.

Mounted within a central cylindrical bore 2010 at the other end of cylinder 201b of brush 201, is a ball bearing assembly, similar to those ball bearing assemblies as aforesaid, and having an outer annular collar 212, an inner annular collar 213, and ball bearings 214 (typical). Slidably received within the inner surface of inner annular collar 213 is one end 215a of cylindrical shaft 215, the other end 2l5b of said cylindrical shaft 215 is fixedly mounted to plate 216, said plate 216 in turn being fixedly attached to the inner surface of inner bathtub wall 2040. In this manner the brush 201, driven by connecting shaft 208 in combination with brush shaft 21 l is freely rotatably about cylindrical shaft 215.

Further, longitudinally disposed within the cylindrical hollow of cylinder 201b is a compression spring 217, said spring 217, the ends thereof pressing against ends 21 lb and 215a of shaft 211 and 215, respectively. By this construction, the brush 201 may be removed from the assembly by first moving the brush laterally in the direction of the wall 2040, thereby compressing spring 217, and clearing end 211a from the inward surface of plate 210. The brush may then be cleared of shaft 215 and removed from the bathtub.

Referring now specifically to FIG. 10, there is shown still a further embodiment of the invention. More specifically there is shown an alternative construction for removing a brush similar to that of FIGS. 7, 8 and 9 from the bathtub cavity. Cylindrical brush 301 comprises a hollow base cylinder 301a having circular bores 301b and 3010 at the respective ends thereof. Mounted with the hollow of base cylinder 301a at each of the ends 301b and 3010 thereof are dowel members 302 and 303, respectively. Formed at each of the ends of dowel member 303 are projecting shaft members 303a and 303b. Shaft member 303b projects inwardly in the hollow of cylinder 301a and member 303a projecting outwardly through central end bore 3010 and into the inner receiving surface of a ball bearing assembly 304 (similar to previously described ball bearing assemblies). Ball bearing assembly 304 is fixed housed within inner bathtub wall 305a. Formed at the ends of dowel member 302 are projecting shaft members 302a and 302b. Member 302a projects outwardly through central bore 30112 of cylinder 301a and into the inner receiving surface of a ball bearing assembly 306 (similar to previously described ball bearing assemblies). At the outer end of projecting shaft member 302a is an internal cup 307 of square configuration for slidably receiving square rotatable shaft 308, said shaft 308, the end other than the received end thereof being attached to the hub of a rotatable drive pulley 310.

Thusly the rotating pulley 310, rotates shaft 308 which in turn rotates projecting shaft member 302a (employing ball bearing assembly 306 for rotation therewith) which in turn causes cylinder 3010 to rotate, in turn rotating projecting shaft member 303a (employing ball bearing assembly 304 for rotation therewith).

Mounted within the hollow of cylinder 301a and disposed between opposed projecting shaft members 302b and 303b, is a compression spring 311. By this manner of construction the brush 301 may be removed from the bathtub by moving the brush in axial direction toward inner wall 305a, thereby compressing spring 311, until the end of projecting shaft member 302a clears the inward surface of inner wall 305b. The other outwardly projecting shaft member 303a at the other end of cylinder 301a may then be cleared of the inner surface of inner wall 305a, thereby freeing the entire brush assembly for removal of the same from the bathtub cavity.

Referring to FIGS. 11, 12, 13 and 14, there is shown still another embodiment of the invention similar to that of FIGS. 4, 5, and 6. Brush 401, similar in construction to aforesaid brush is 1, and 101, is housed within bathtub 404, tranversely disposed between inner walls 404a and 404b and outer walls 4040 and 404d, respectively. Said cylindrical brush is mounted on axially rotatable shaft 402 so that said brush rotates with said shaft. The shaft 402 desirably has a square crosssectional configuration.

The end of the shaft 402a, opposing wall 40412, is slidably received in the inner surface of an inner annular collar 403, the outer surface of said collar is grooved 'to receive ball bearings 405 (typical). And surrounding the ball bearings is an outer annular collar 406 with a groove on the inner surface of the outer annular collar 406 so as to retain the ball bearing therein. This ball bearing assembly is similar to other assemblies in this embodiment, as well as other embodiments as will be pointed out hereinafter.

Fixedly attached to the outer surface of outer annular collar 406 is lower end of a first vertical member 407 which is perpendicular disposed to shaft 402. The upper end of vertical member 407 is fixed attached to the outer surface of an outer annular collar 408 of a ball bearing assembly similar to the previously described ball bearing assembly; the components being an outer annular collar 408, ball bearings 410 (typical), and inner annular collar 409.

Slidably retained within the central hole of inner annular collar 409 is a portion of a support drive shaft 411, said support drive shaft being in parallel disposition to aforesaid brush shaft 402. One end 411a of said support drive shaft 41 l is centrally mounted at one end of motor M-2.

A second vertical member 416, similar to vertical member 407, and in parallel disposition therewith, is rotatably interconnected from support drive shaft 411 to connecting shaft 420, by means of ball bearing assemblies 460 and 461, respectively. Ball bearing assemblies 460 and 461 are similar to the aforesaid ball bearing assemblies in their construction and operation.

Mounted on said support drive shaft 411, between the end 412a thereof and motor M-2 are ball bearing assemblies, 413 and 414, similar to the aforesaid assemblies. Said ball bearing assemblies 413 and 414 are affixedly mounted to plates 413a and 414a, respectively; said plates, each in turn, straddle, interconnect and are affixedly mount to tranversely disposed support bars 452 and 453, to be further discussed hereinafter.

Mounted within the inner annular collar of ball bearing assembly 461 is a rotatable connecting shaft 420 having on the inward end thereof a cup 421, the inner periphery of cup 421 receives one end 402b of square brush shaft 4102 by means of a ball and socket construction 470, similar to that shown in FIG. 3 hereof.

Thusly, the brush 401 is in parallel disposition to shafts 411 and 402 and joined thereto through vertical members 416 and 407, respectively, and through the aforesaid four ball bearing assemblies. Mounted to each of said vertical members, are hand grips 416a and 407a, respectively, so that a person in the bathtub can grip said hand grip. By this construction the brush may be manually positioned along an arcuate path, the radius of the arc being the length of the vertical members. In this manner the brush may by gripping the hand grips be positioned to several heights in the bathtub as is desired.

Referring to FIG. 12, there is shown the end 411a of support drive shaft 41 1 which shaft rotates with actuation of motor M-2. Mounted near the other end 4110 is an upper pulley 424 having retained on the inner periphery of a central bore therein, an annular ring 425, said ring 425 frictionally held to drive shaft 411. The peripheral groove of upper pulley 424 frictionally receives endless belt 426.

Referring again to FIG. 12, there is shown the lower pulley 427, similarly constructed to the upper pulley 424, and having an inner annular ring 428, said ring frictionally receiving the aforesaid connecting shaft 420. The peripheral groove of the lower pulley frictionally receives the aforesaid endless belt 426 in a manner similar to that as afore-described for the upper pulley 424.

By this manner of construction, the actuated motor M-2 rotates drive shaft 411 causing rotation of upper pulley 424 thereby moving endless belt 426 which in turn translates its movement to lower pulley 427 which in turn causes rotation of connecting shaft 420 which in turn rotates shaft 402 thereby rotating cylindrical brush 401.

The top side walls 404e and 404f of bathtub 404 are provided with guide channels 450e and 450f, respectively. The guide channels are pressedly held between walls W5 and W6 by turnbuckle means 451e and 45lf are two sets of roller-mounted parallel, spaced, support bars 452 and 453 said bars in parallel disposition to shaft 411, and brush shaft 402; bar 452 having rollers 452a and 452b, freely rotatable thereon; and bar 453 having rollers 453a and 453b, freely rotatable thereon. The bars 452 and 453 per se do not rotate, but rotational bearing surfaces (not shown) permit free rotation of the rollers 4520, 452b, 453a and 453b. The rollers upon rotation roll through and within aforesaid guide channels.

Guide channel 450f is provided with a slot 450g for receiving one end portion of support bars 452 and 453, so as to permit said bars to guidingly pass through said slot. A motor support plate 490 tranversely straddles and is affixed to at one end portion of bars 452 and 453. The motor M-2 is of course mounted to said plate 490. This manner of construction is preferred to that shown in FIGS. 4 and 5, insofar as the motor is not directly housed over the bathtub.

Still another distinct feature of the embodiment of FIGS. 11-14, is a protective housing 495, enclosed about the pulley and belt system as aforedescribed. The housing is mounted on and slidably receives drive shaft 411 and connecting shaft 420.

The housing 495, protects a person in the bathtub from the rapid motion of the belt and pulley system.

A further feature of this embodiment is the addition of paddle wheels 498 and 499, slidably received on shaft 402 at opposite ends of brush 401. In operation, shaft 402 rotates and in turn rotates said paddle wheels so as to agitate the water in the bathtub, so as to provide additional therapeutic massaging action to a person in the bathtub. The paddles of the paddle wheels may be of any desired manner of configuration deemed suitable. The paddle wheels are of soft rubber material.

The mechanical operation of this embodiment of FIGS. 11-14 is similar to that of FIGS. 4-6.
