Referring to the embodimentof the invention shown in FIGS. 1-7, association with anessentially conventional bath tub it) having the usual drain opening 12 and overflow opening 14, there is provided the hydrotherapy equipment of the invention which comprises generally a head unit 16, a pump housing 18, an electric motor 26 adapted to drive shaft 22 which in turn drives the pump impeller within housing 18, and a flow conduit system comprising manifold 24, conduit 26 which provides for two-way flow between manifold 24 and pump housing 18, conduit 28 adapted to interconnect manifold 24 to waste when the tub 1% is being emptied, and overflow conduit 30 adapted to interconnect the overflow opening 14 with conduit 28 so that excess water entering the tub will be directed to waste. The pump housing 18 and the motor 20 mounted thereon are appropriately supported outside of the tub, as by legs 32 (FIG. 5) which engage floor 34 (FIG. 2). In FIG. 2, the pump housing and motor are shown as being located within a space 36 which is enclosed at the top by a permanently positioned cover member 38 and a removable louvered cover member 40, the latter enabling the circulation of air into and outof space 36 to cool the motor and enabling access to the motor and the related parts of the equipment disposed within space 36.

The head 16 is provided with an internal inwardly and outwardly opening sleeve 42, a valve seat 44, and an open ended nozzle member 46, the latter having external threads in engagement With internal threads formed in sleeve 42 and being provided with a multi-fingered handle .48 whereby the nozzle 46 may be rotated by hand or foot in one direction to move it inwardly of the sleeve 42 or in the other direction to move it outwardly of the sleeve 42 to thereby control the fiow of water through said nozzle. When the nozzle 46 is moved fully inwardly of sleeve 42, its inner end is brought into engagement with the valve seat 44 to prevent discharge flow from the nozzle, and when the nozzle 46 is moved outwardly away from seat 44, the discharge flow from the nozzle is increased.

The head 16 is providedtwith means for entraining air in the water issuing from nozzle 46 in a greater or lesser degree, saidsrneans comprising a tube 50 having its lower end communicating with chamber 52. defined within the head and having its upper end provided with a rotatable cap 54 having one or more openings 56 adapted to be brought into and out of communication with one or more corresponding openings formed in the side of the upper end of tube 50, and air port 53 (FIG. 2) formed in the internal wall 60 of the head and providing for the passage of air from chamber 52 into the chamber 62 defined between the nozzle 46 and the sleeve 42, and one or more air ports 64 enablingrthe induction of air from chamber 62 into the nozzle 46 by the water passing through the latter.

The head 16 is further provided with the dependent sleeve 66 which fits over the tubular upper end of a valve member indicated generally at 68. The lower or valve control portion 70 of the valve member 68 is supported for rotation by the surface 72 of manifold 24. The head 16 is supported on compression spring 74 (FIG. the latter being in turn supported on flange 76 of valve member 68. Complemental means 78 secure the head 16 to the valve member 68 so that rotative movement of the former is imparted to the latter. A manually operable spring-urged detent 80 (FIG. 2) having a reversely turned operable end extending through sleeve portion 66 of head 16 and engageable underneath the flange 82 of annular screen member 84, the latter having its lower end 86 secured within the drain opening 12, serves to releasably secure head 16 at a predetermined height above the bottom of the tub 10.

The manifold 24 has defined therein (see FIG. 3) a low pressure chamber 88, a high pressure chamber 90, a main passageway 92 communicable with drain line 28, and an auxiliary passage 94 which communicates with drain line 28.

The conduit 26 has defined therein passageway 86 which interconnects the eye, or inlet, portion 98 of the pump impeller with the low pressure chamber 88 of manifold 24 and with the conduit, or passageway, 92 (FIG. 3), and conduit 26 has further defined therein a passageway 100 which interconnects the outlet, or high pressure, side of the pump with the high pressure chamber 90 of manifold 24.

Assuming that the bath tub is semi-filled with water, preferably to a level above the nozzle 46, the space within the head 16, the conduit 26 and the pump housing 18 will be likewise filled with water, the input water to the tub entering these spaces by way of the inlet grill, or screen,

' 84 and the space defined between said grill and the valve element 68, said latter space being in communication with the low pressure chamber 88 of manifold 24 and passageway 96 of conduit 26.

Upon energization of motor 20, the pump delivers pressurized water through passageway 100 of conduit 26, into high pressure chamber 90 of manifold 24, from chamber 90 through port 102 (FIG. 6) and into the interior of the upper tubular portion of valve element 68, from the valve element 68 into head 16, and then out of the unit as the relatively high pressure submerged stream through nozzle 46. The cycle of water circulation is completed by flow of the water through the grill 84, the low pressure chamber 88, the passageway 96 of conduit 26, and the eye, or suction side, 98 of the pump impeller. A removable and replaceable Web 104 of filter material is positioned at the inner side of grill 84 and serves the purpose of filtering the water which passes from the tub to the pump.

As previously indicated, the user of the equipment may control the rate of delivery of water into the tub by the pump by adjusting the nozzle 46 and he may control the amount of air entrained in the Water stream entering the tub by adjusting the air control cap 54 on air tube 50. Also, as previously indicated, the user may vary the angular position of the nozzle 46 relative to longitudinal axis of the tub by rotating the head 16. Foot control means for this purpose are provided in the form of foot bars 106 which are integral with the head 16 and extend laterally therefrom. A range of angular swing of head 16 of about 45 in each direction away from the longitudinal axis of the tub is adequate to provide the user with any desired flow pattern within the tub. Throughout this total of 90, and even more, of angular variation of the head 16 for practical use of the unit, the port 102 of valve element 68 will have a sufficient degree of communication with the high pressure chamber 90 of manifold 24 so that the rate of flow of the high pressure stream out of the nozzle 46 for any given setting of the nozzle will be essentially unvaried. In other words, the flow space defined between the inner end of the nozzle 4 46 and the valve seat 44 is the limiting factor determining the rate of outlet flow through the nozzle for any given setting of the head throughout the about range of adjustment of the head for practical use.

While the chamber 92 is in communication with the low pressure chamber 88 of manifold 24 and the suction passageway 96 of conduit 26, gate valve 103 (FIG. 2) closes off the chamber, or passageway, 92 from communication with the drain line 28 during normal use of the unit. While the passageway 94 of manifold 24 is in communication at all times with the drain line 28, communication between the passageway 94 and the low and high pressure chmbers 88 and 90 of manifold 24 is prevented by valve element 63.

In the event that the user continues to fill the tub with water through the tub feed faucet 110 to the point where the water level in the tub reaches the tubs overflow opening 14, the overflow of water will pass through the opening 14, down tube 39, through apertures 112 in the upper side of gate valve 108, through the open lower end of the hollow gate valve element 108, through port 116 in manifold wall 118, into passageway 94, and from the latter into the drain line 28 and through the trap 120 to waste.

After a desired period of use of the unit, the user need merely rotate the head 16 through 180 so that the outlet of the nozzle is directed toward the adjacent end wall of the tub. Before this degree of swing of the head 16 is completed, the port 102 of valve element 68 is brought completely out of communication with the high pressure chamber 90 of manifold 24, thereby shutting off pressurized flow to the nozzle and bringing the high pressure chamber 90 into communication with passageway 94 through undercut port 122 (FIGS. 6 and 7) formed in valve element 68 and port 124 formed in the manifold 24. Continued operation of the unit in this condition serves to pump the water from the tub and into the drain line 28 to waste. Means hereinafter described are provided to deenergize the motor 20 after the water level in conduit v26 and manifold 24 has been lowered to a predetermined degree. When this occurs, the conduit 26 and the manifold 24 are brought into communication with the drain line by the raising of the gate valve 108, the latter operation being effected by manual rotation of the control arm 126 affixed to crank lever 128 to thereby raise rod 130 and the gate valve 108 carried thereby.

When the entire system has been drained through the drain line 28, save for the relatively small amount of residual water within passageway 94, the unit is conditioned for subsequent use by dropping the gate valve 108 to the position of FIG. 2 and by rotating the head 16 to interrupt communication between chamber 90 and passageway 94 and bring the port 102 of valve element 68 into communication with chamber 90. The residual water within the passageway 94 is then fully blocked off from access to the hydrotherapy unit or the tub and it will be flushed from the system through the drain line 28 at the end of the next session of use of the unit, i.e., when the next charge of water within the tub is pumped therefrom through the passageway 94 in the manner above described.

In FIG. 8 there is exemplified a control system for the hydrotherapy unit.

Lines

132 and 134 furnish line voltage for the operation of the pump motor 20, the motor being actuated upon operation of the relay indicated generally at 136 and comprising coil 138 and switch contacts 140 and 142. The relay 136 is controlled by a control circuit indicated generally at 144.

The control circuit 144 further comprises switch 148, a master control switch 152, and a pressure-sensitive switch 154, the latter being mounted within the high pressure passageway 100 of conduit 26.

Switches 148 and 152 are desirably positioned on a walllocated face plate of an outlet box which is positioned adjacent to the tub 10. The switch 148, although not so amasao illustrated, my be of the timer type adapted to be closed to be closed for varying selected periods of time in accordance with the desire of the user as to the particular length of time the hydrotherapy equipment is to be used. Prior to entering the tub, the user of the equipment operates switch 148. Switch 152 is preferably of the type which requires a key to operate, and thereby the provision of switch 152 places the operation of the hydrotherapy equipment under the control of the possessor of the key for the operation of this switch. This is not only desirable in motel and hotel installations to insure that the unit will not be used by someone not authorized to do so, but it is also desirable in connection with residential installations in order that those in authority may control the extent and time of use of the equipment.

After the switches 14% and 152 have been closed, the user commences the filling of the tub with water. When the water level has risen above the nozzle 46, the static pressure of the water applied to the pressure-sensitive switch 154 causes said switch to close and thereby cnergize the motor 2% and the pump driven thereby. Dur ing the time the pump is operating, the switch 154 is sub jected to a dynamic pressure condition, and switch 154 is sufiiciently sensitive to this condition to remain closed during the power draining of the tub until the water level within passageway of conduit 26 has dropped a substantial degree within said passageway.

In FIGS. 9-11 there is shown a somewhat simplified embodiment of the hydrotherapy equipment of the invention. Here, the tub 216 is provided with the drain open ing 212 and with an overflow opening which communicates with a downpipe 214. A face plate 215 slotted at its underside for the admission of overflow water to pipe 214 is secured to the pipe 214 through the overflow opening. The head 216, similar to that previously described, has a sleeve 217 at its underside which is disposed in telescoped relation to valve tube 218, the head being supported by head base 220 which has an externally threaded sleeve extension 221, the latter being threadedly engaged with and supporting the manifold 222. To the lower end of manifold 222 there is secured, as by bolt ing, a valve seat member 224 having a conduit extension 225 which is connected to the downpipe 214.

The head base 220 is provided with a lateral slotted portion 228 over which is removably placed filter pad and retainer screen means indicated generally at 230.

The head 2116 is provided with a key, not shown, which fits within a vertically disposed slot, not shown, in valve tube 218, thereby securing the latter to the head 216 for rotative movement with the head. The head is also provided with a lock control button 232 which is adapted to operate a spring-urged tang, not shown, to lock the head to the head base 225) by engagement of said tang beneath the inwardly directed upper flange portion 234 of head base 220.

The lower end of tube 218 is provided with

inflow slots

236 and 238, and there is secured to the lower end of the tube 213 by means comprising a U-shaped yoke 249 a valve elemcnt 242. The arms of the U-shaped yoke are secured to the exterior of the tube 218, and the upper ends of these arms serve as a seat for compression spring 244, said spring reacting against the manifold partition 246 to urge the valve 242- against the valve seat 248.

Manifold partition 246 divides manifold 222 into a suction compartment 253 and a pressure compartment 252, both of said compartments being in communication with separated passageways in the conduit 254. The output side of the pump disposed within housing 256 communicates with the pressure chamber 252 and the input side of the pump communicates with the suction chamber 250; Pump motor 258 is mounted on pump housing 256. The load constituted by housing 256 and motor 253 may be borne by conduit 254 through the flanged connection 260 between conduit 254 and a matching con duit 2&2, forming part of the pump housing 256.

It will be appreciated that the path of flow of the water is as follows: Inwardly of the lateral slotted portion 228 of head base 220; downwardly through the sleeve extension 221 of the head base and into the suction chamber 250; from suction chamber 250 through communicating low pressure passageways in

conduits

254 and 262 to the eye of the pump impeller; outwardly from the periphery of the impeller to communicating high pressure passageways in

conduits

262 and 254 to high pressure chamber 252; through

slots

236 and 238 formed in tube 218; upwardly through tube 218 to the head 216; and out of the nozzle element of head 216.

To drain the tub, the head 216 is turned so that the outlet of the nozzle is directed toward the adjacent end wall of the tub. This movement is imparted to tube 218 and by the tube to the valve element 242 to rotate the latter from its covering relation to the valve opening 248. The subsequent liow of water from pressure chamber 252 will be through the valve port 248 to line 226 and then downwardly through downpipe 214 and through trap 264 to waste. It will be appreciated that the entiree part of the discharge conduit system is drained to waste.

It will be further appreciated that it is not necessary to drain the tub by means of the pump, either with respect to the modification of FIGS. 9-11 or with respect to the embodiment of the invention shown in FIGS. 1-7. The system can be gravity-drained by actuating the on-otf switch to deenergize the pump motor and pump. In such event, gravity draining will result from a rotation of the head to direct the nozzle outlet toward the adjacent end wall of the tub. 4

A further modification oi the hydrotherapy equipment of the invention is shown in FIGS. 12-14. With respect to this modification, only those features. will be mentioned which are different from those of the modification of FIGS. 9-11.

The essential ditierence between these two modifications is that the one shown in FIGS. 12-14 has the pump housing 356 and the pump motor 358 inverted and mounted beneath the tub in depending relation to the manifold 322 and the low pressure conduit extension 364 which is made integral with the manifold 322 and that part of the housing 356 in which the pump impeller 366 resides.

Inflow from the tub to the pump impeller takes place through the head base 329 and the low pressure conduit 364. Outflow from the impeller is received by chamber 368 in housing 356 and passes into manifold chamber 352, after which the path of movement of the pressurized water is the same as that described in connection'with the modification of FIGS. 9-11.

The parts or elements of the embodiment of the invention shown in FIGS. 12-l4 which correspond toor are identical with the parts or elements of the embodiment shown in FIGS. 9-11 are designated by corresponding reference numbers to which 100 has been added.

It will be noted that in the embodiment of FIGS. -91l the pump housing 256 is provided with an air vent line 263 which is in communication with the upper end of the overflow pipe 214. The positional arrangement of the pump with respect to the components of the conduit system external to the tub call for the pro-vision of such an air vent line in order to prevent the pump from becoming air locked during the course of a subsequent introduction of water into the tub. On the other hand, the positional arrangement of the pump with respect to the water conduit tree in FIGS. l214 is such that the pump cannot become air locked, and hence no air Vent line is suggested for this last-described embodiment.

While a number of embodiments of the invention have been shown and described, it is to be understood that the hydrotherapy equipment of the invention is subject to considerable change and modification from the standpoint of both the skill of the art and that of the rule of equivalency, and that the scope of the invention is to be appro- 7 priately construed in the light of this and the appended claims.
