or any other suitable material,

vided on corresponding extremities thereof with couplings 7 and 8, respectively. The coupling '7 may be of any suitable type adapted to be readily connected with and disconnected from a faucet or other source of water or liquid under pressure, and the coupling 8 may also be of any suitable type provided, if desired, with a screen 9, and adapted to admit air or other gas in the conduit 6. The coupling, ends of the conduits and-6 extend separately out of a coupling 10 formed on one extremity of a flexible hose 11 or the like provided therein with passages 12 and 13 that form continuations of the conduits 5 and 6, respectively.

The opposite extremity of the hose 11 is provided with a coupling 14 having two branches 15 and 16 which communicate with the passages 12 and 13, respectively, and are enclosed'in a hollow handle 17 provided at one end thereof with an opening through which the coupling 14 extends.

-The opposite end of the handle 17 is fitted in one end of a tubular guard or casing 18 and secured thereto, as by small machine screws 19 or the 15, 16 are preferably formed of hard rubber or other suitable rigid substance vulcanized to or formed integrally with the hose 11.

The handle 17 may be of wood, metal, hard rubber, or any other suitable material, and said handle may be secured to or fitted on the guard or casing 18 in the described or any other suitable manner.

Connected in any suitable manner with the branches 15 and 16 of coupling 14 are conduits 20 and 21, respectively, which are made of metal and extend through the handle 1'7 into the guard or casing 18 that is likewise made of metal or other suitable material. This guard or casing 18 is provided interiorly thereof with a manifold having a conduit or compartment 22 connected in any suitable manner with the conduit 20, and a conduit or compartment 23 connected in any suitable manner with the conduit 21. This manifold is indicated broadly at 24 and said manifold is preferably formed by an elongated box 25 of rectangular cross section, and a cover 26 fitted on said box in spaced relation with the wall 27 thereof. The cover 26 has a fiuidtight fit with the box 27 and may be secured thereto in any suitable manner. The box 25, in turn, is secured in any suitable manner to the guard or casing 18 within the latter, and said guard or casing forms one wall of the box in opposed relation with the wall 27 thereof.

The manifold 24 is provided with injector means preferably comprised by a plurality of injectors indicated broadly at 28. These injectors extend transversely of the guard or casing 18 and are axially alined with openings 29 in the wall thereof. The injectors 28 are each preferably comprised by two tubes 30 and 31 of different diameters extending one within the other, the tubes 30 being secured to the wall 2'7 of box 25 in any suitable manner and communicating with the compartment 23, and the tubes 31 being secured to the cover 26 in any suitable manner and communicating with the compartment 22. The injectors 28 serve tomix gas and liquid received from the compartm nts 22 and 23, respectively, and discharge jets or sprays of said mixture under pressure and at high velocity through the openings 29 in the guard or casing for application to the body of a person as hereinafter described.

The guard or casing 18 is open at the end thereof opposite that carrying the handle 17, and said handle is preferably hollow and provided therein with slots 32 extending between opposite annular end portions 33 and 34 of the handle. The screen 9, and a screen 36 in the inner end of the conduit 21, prevent dirt or other matter from entering the various conduits, the manifold, and the injectors, and thereby insure that said conduits, manifold, and injectors will function properly and not become clogged or stopped up by any extraneous matter. The guard or casing 18 may, if desired, be provided with lugs 37 which are secured to or formed integrally with said guard or casing and fitted with rubber sleeves or the like 38. Said lugs and sleeves serve to support the guard or casing 18 when the apparatus or appliance is not in use, and the sleeves 38 prevent marring or scratching of the surface of any equipment on which the apparatus or appliance might be supported.

The above described portable fluid massage apparatus or appliance may be used in tubs, pools, or other bathing places as, for example, in a tub 39 such as indicated in Fig. 1 of the drawings. This tub 39 is equipped with a mixing faucet 40 for hot and cold water received from any suitable source through pipes such as indicated at 41. In this case, the coupling 7 is connected with the faucet 40, and the Water under pressure is delivered through the conduit 5, passage 12, conduit in branch 16 of coupling 14, and conduit 21, into the compartment 23 of manifold 24. The conduit 6, in the use of the portable apparatus or appliance as stated, is preferably supported by a hook 42 secured in any suitable manner to the coupling 8 and detachably engaged over the upper edge of the tub 39 to hold'said coupling in a position substantially as shown in Fig. 1 of the drawings. The water delivered under pressure into the compartment 23 of manifold 25, as previously pointed out, passes through the tubes 30 of the injectors 28, and tubes 31 thereof, and the openings 29 in the guard or casing 18. The tubes 30, as clearly shown in Fig. 3 of the drawings, extend within the tubes 31 in spaced relation therewith, so that the passage of water through the injectors in the manner stated,

creates suction in the compartment 22, the conduit 20, the passage 13, and the conduit 6, thereby drawing air into the compartment 22. This air is entrained by the water delivered through the tubes 30, mixed therewith in the injectors 28,

and discharged therefrom through the openings 29 in the guard of casing 18. The tub 39 may have previously been filled with Water before attachment of the portable apparatus or appliance to the faucet 40, or said tub may be filled by delivery of the water therein through said apparatus or appliance after attachment thereof to said faucet. The tub 39 is provided with the usual drain opening 44, stopper 47 therefor, drain pipe 48, and overflow outlet 45.

A person in the tub 39 may, through the medium of the handle 17, move the portable fluid massage apparatus or appliance about the tub, and under the surface of the water therein, as desired, and thus apply the jets or sprays disti'ons'of the :body with a beneficial and healthful eflect thereon. The jetsor sprays consisting of a mixture of liquid and-gas dlscliarged under pressure and at relatively :high velocity below the surface of the Water and against the body of the person therein produce, in eiiecha vibratory message on the body or the person, which massage may be-"of more or less vigorous character, inaccordance with the pressure of the liquid as regulated by the :handle 40 or the faucet l'i). Itwill,

of course, be understood that instead of delivering water or other liquid under pressure to the portable apparatus or appliance, the air or other-gas could bedelivered thereto under pressureand the water could be supplied from the tub to *thefportable apparatus or appliance through In "either-case, the effect produced upon the body of *the'person is'substantiallythesamc, and the device would be connected with the source or fluid under pressure, andoperated, in substantially the "same manner. Various forms'of couplings could connected with the conduits 5 and 6, for the form a fluid-tight joint. spout is then delivered through the tube 51 and the conduit 5 to the portable apparatus or apdelivery therethrough of liquid and gas, respectively. In Figs. 5 and 6, for example, there is shown a'form of expansible-coupling for connection-with a iaucet'having a relatively large spout 49 and outlet opening 50. ihis coupling consists of a tube-5i provided atone end with serrations 52 and thereby connected with the liquid ccnduitfi of the portable apparatus or "appliance. The opposite end of the tube 51 is provided with a shoulder 53 engaging one side 'of a rubber ring '54 which is fitt'edon the tube 51 against'said shoulder. A

ring '55 loosely mounted on the tube 51 is adapted to engage the rubber 'ringfi l and expand the same when pressed therea'gainst by a nut 56. This nut "56 is fitted on a threaded portion 57 of the tube 51, and said nut is provided with operating handies 58. When the coupling end of the tube 51 is inserted in the opening '50 of spout 49, the nut 56 is turned by the handles 58 to press the ring against the ring 54 so that the latter is expanded against the inner periphery of the spout 49 to The water from said pliance, as previously described. When it is desired to disconnect the apparatus or appliance from the spout 49, the nut 56 is turned by the loandies 58 to release the ring 55 from ring 54 so that the latter contracts and the coupling may be disconnected.

In the embodiment of the invention shown in Figs. "7 to 10, inclusive, the conduit 11, insteadof being connected with a portable apparatus or appliance, is connected with a normally stationary manifold .indicated'broadly at 59 and having substantially the same construction as the manifold 24. In this case. the conduit 11 is provided at one end with flexible branches so and 61 com municating with the Water and air passages 12 and 13 (Fig. 2) respectively, which, in turn, cornmunicate with the conduits 5 and 6, as before described. The branches 60 and 61 are connected in any suitable manner with pipes 62 and 63, respectively, which connect with, and are secured in any suitable manner to, pipes or conduits G4 and 65 which are closcd'at their opposite ends by any suitable means for this purpose; The pipes Stand 65 extend transversely of the tub SQ-and have connected therewith, and extending at right angles thereto, pipes or conduits 66 and 6'7,'respectively. The pipes 66 and 67, in turn, are

connected through one end or the mam-tors 59,

with compartments or conduits Stenci -69 thereof, respectively. The conduits '68 and 89 are separated =irb'm eaeh otner leagues-many of the man-ifold and at the o posite ends thereof, the con-" to-provide fiui'dtig l'iit jc iints between the The lower part of the manuals 59 provided a series of elongated box l ike compartments or conduits 70 of rectangular "cross section and similar conduits or compartments "-71 cats ding transversel or the on or at opposite-ends thereof and ommunicating therewith as before described The upper part of the manifold b9 is constituted by a series or elongated channel shape portions "72 and similar mo portions extending transversely of the tioiis 72 at opposite ends thereof and communi- Gating therewith. The manifold 59 is provided with injectors each comprising a of tubes 74, 75 of different diameters (intending one Within the other as in the ease of the ini'otors previously described. The tubesfm are to the conduits or -'conipartments to on the top- 'walls thereof and communicate with said compet tments as clearly shown in Fig. 9 or the drawings. The tubes '15 are secured to the topof the channel members 7-2 and communicate with the chainbers 69 formed by said members and the up er walls of the conduits or compartments 70. The manifold 59' is connected in any suitable manner with cross members 76 made of channel iron or other suitable material. These cross members '76, in turn, are secured any suitable manner to a support 7'7 on the underside thereof. This support 7'7 is provided with openings 7 8 axia'ly all-nod with the injectors '74; 75 and through which the latter discharge jets or sprays of fluid in a manner to be presently described. The support 7'7 has secured thereto in any suitable manner legs 79 which rest on the bottom of the tub 39 and are provided with pads "80 of rubber or other suitable material that prevent mar-ring or scratching of the surface of the tub.

When the tube 5 is connected with the faucet 40, as shown in Fig. '7 of the drawings, and the tube 6 is supported on the tub 39 by the hook 42, Water under pressure may be delivered from the faucet '40 through the described connections therefor with the manifold 59, into the compartments 68 thereof.

In the embodiment of the invention shown of the rotary type including a'driven shaft 84 having fixed thereon a sprocket 85 around which passes a chain 86. The chain 86 also passes around a sprocket 87 which is fixed on the armature shaft 88 of an electric motor 89 supplied with current from any suitable source. Mounted in the tub 39 in any suitable manner, is a support 90 arranged to be submerged in water supplied to the tub by suitable faucets or the like (not shown). Mounted on the support 90 is a standpipe 91 connected through the medium of a pipe 92 with the inlet 93 of the pump 82. The water is drawn from the tub through the standpipe 91, the pipe 92 and the inlet 93 of the pump and forced back through the outlet 95 of said pump through a pipe 96,-a fitting 97 connected with said pipe and the standpipe 91, a pipe 98 .connected with said fitting, and the manifold 83 which is connected with the last named pipe. A continuous circulation of water and air is thus maintained in the described circuit including the manifold, the pump, and the connections therebetween.

The manifold is connected with and supported by the support 90 in any suitable manner, and said manifold has a construction similar to that of the manifold shown in Figs. 7 to 10, inclusive, of the drawings. The manifold 83, however, has

. connected with the upper conduit or compartment 99 an air pipe 94 which extends upwardly toward the top of the tubSQ. The lower compartment 100 of the manifold has connected therewith the pipe 98. The manifold 83, as in the caseof the manifold previously described, is provided with injectors for mixing and discharging liquid and gas, and these injectors are each comprised by tubes 102 and 103 of different diameters extending one within the other, as clearly shown in Fig. 11 of the drawings. The tubes 102 are secured to the upper wall of the compartment 100 and communicate with the interior thereof, and the tubes 103 are secured to the upper wall of the compartment 99 and communicate with the interior thereof The injectors 102, 103 are axially alined with openings 10% formed in the support 90, so that when a person is positioned on said support, jets or sprays of air and water will be delivered from the injectors. through the openings 104 against the body of the person to produce a fluid vibratory massage action on the body of the person, with the resulting invigorating and healthful effect previously referred to. The air is supplied to the injectors 102, 103 through pipe 98 and compartment 99, the water forced through said injectors creating suction in said pipe and compartment so that air from the atmosphere is drawn therethrough, entrained and mixed with the water in the injectors, and discharged therefrom with the water, as before described. H

In the embodiment of the invention shown in Figs. 12 and 13 of the drawings, a series of tubs 39, arranged in separate rooms or compartments if desired, are connected with a single source of fluid under pressure supplied to manifolds 105 in the several tubs from a tank 106. For this purpose, the lower compartments or conduits 107 ofthe manifolds 105have connected therewith pipes 108, which, in turn, are connected with a pipe 109 that is connected with the tank 106. Suitable valves 110 may be provided in the pipes 108 to selectively or simultaneously control the delivery of air or gas under pressure from the tank 106 into the compartments 107 of the manifolds 105. The tank 106 has connected therewith one end of a pipe 111 provided with a suitable check valve 112 and having an opposite end connected with the outlet 113 of a rotary air compressor 114. This compressor 114 may be of any suitable construction including a driven shaft 115. Fixed on the shaft 115 is a sprocket llfiaround which passes a chain 117 that also passes around a sprocket 118 which is fixed on the armature shaft 119 of an electric motor 120.

Motor 120 receives current from any suitable source and drives the compressor 114 which therefore acts to supply the tank 106 with compressed air or other gas, through the pipe 111.

The supply of air in the tank 106 may, if desired, be regulated automatically, and for this purpose there is mounted on said tank, in communication with the interior thereof, a diaphragm 121 connected with one end of a lever 122 so as to rock the same about its pivot 123 as the pressure of the air in the tank 106 decreases and increases. The pivot 123 for the lever 122 is provided by a bracket 124 secured in any suitable manner to the tank 106, and the end of the lever opposite that connected with the diaphragm 121 has pivotally mounted thereon a lever 125 arranged for limited swinging .movement on the lever 122 between pins 126 secured thereto. Carried by the lever 125 and insulated therefrom in any suitable manner is a contact 127 adapted to engage contacts 128 carried by a bracket 129 and insulated therefrom in any suitable manner.. The bracket 129, in turn, is secured in any suitable manner on the tank 106. The contacts 128 are provided with suitable terminals 130 with which are connected lead wires 131 that, in turn, connect with one side of a source of electric current 132 and one terminal 133 of the electric motor 120. The opposite side of the source of electrical current 132 is connected by a lead wire 134 with the other terminal 135 of said electric motor.

When the tank 106 is sufficiently charged with air, the diaphragm 121 moves outwardly thus tilting the lever 122 so that the contact 127 is moved out of engagement with the contacts 128, and the motor 120 and the compressor 114 are stopped. When the pressure of the air in the tank 106 decreases sufficiently to enable the diaphragm 121 to move inwardly, the lever 122 is tilted so that the contacts 127 and 128 are engaged, thus starting the motor 120 and the compressor 114, to recharge the tank 106. It will thus appear that the tank 106 is automatically charged each time the pressure therein decreases sufficiently to enable the diaphragm 121 to move and engage the contacts 127, 128, and that as soon as the tank 106 is recharged, the motor and compressor will be stopped, as before described. The manifolds 105 are substantially the same in construction and operation as those previously described, except that the air compartments 107 are provided in the lower part of the manifolds and water compartments 136 are provided in the upper part of the manifolds. The manifolds 105 are secured in any suitable manner to supports 137 and depend therefrom as clearly shown in Figs. 12 and 13 of the drawings. The supports 137, in turn, are mounted in any suitable manner in the several tubs, and said supe tte, t ytddtithi smote o i "t te i tt w th et t i eve bs; n aid emn t tt nte W t r is uni d to he tu s? ens; d aine therettqm b u t zle ettttt and de in lat e l t e it t 51pm); k
