INVENTOR Patented Nov. 3, 1942 UNITED STATES 9 Claims.
My invention relates to improvements in therapeutic bath cabinets.
A primary object of my invention is to provide means whereby a patient undergoing hydrotherapy and thermal treatments may be subjected to local treatments by impacting jets, including impact and heat treatments for the purpose of eliminating congestion, improving circulation, and otherwise tending to restore the parts so treated to a normal healthy condition.
My invention also contemplates the use of localized impact jets for the purpose of excitation or relaxation of the nervous system through the spinal nerves, while the patient is reclining on his back.
Further objects of my invention are to provide means for varying the character of the impacting jets, varying the' range of such jets to increase or diminish the area of the surface to which they are being applied, and for changing the direction of certain of such jets in such a manner that they may continue to be supplied with fluid from pipe connections within the cabinet Walls while the jetting nozzles are being shifted from one position to another; and in general toprovide improved means whereby an attendant may subject the patient to localized impact and heat treatments while administering thermal hydro treatments.
In the following description reference is had to the accompanying drawings, in which Figure 1 is a side elevation of my improved cabinet.

Like parts are identified by the same reference characters throughout the several views.
A bed composed of wooden slats l0 forms the top of a base portion ll of my cabinet, which is adapted to house the piping, and may be supported from the floor by legs l2. The slats [0 are covered by a sheet metal poly-sided housing lid composed of longitudinally extending panels I 3, one of which is provided with windows I4 through which the patient may be viewed. This housing is hinged to the base portion at [5, whereby it maybe lifted and swung backwardly to admit the patient. One end wall E6 of the lid is provided with an opening through which the head of the patient may be projected and supported upon a table l8 which is hinged to the housing at l3 and may be adjusted at various angles by means of a brace 20, suitably notched at 2| to engage a cross pin 22 carried by a bracket 23. The lid or housing constitutes a hood adapted to enclose the body and'limbs of a patient undergoing Water or vapor treatments.
Hot and cold water supply pipes and 3| lead to a suitable mixing valve 32 mounted on the front wall of the base portion II and connected at 33 to deliver water to a cross pipe or header 34 within the chamber, this header having outlet valves operable by exterior handles 35, 36, 31 and 38, for purposes hereinafter explained. The mixing valve is controlled-by the handle 39.
Within the base portion I l I provide a sheet metal water container suspended from near the top of the base portion and having convergent downwardly inclined walls and a bottom wall 46 connected with a drain pipe 41, drainage being controlled by a valve 48 having its handle 49 connected by a chain 5!] with a valve operating member or handle 5|.
The valve will preferably be spring actuated, a coil spring 52 serving to normally hold the valve in a closed position, to be opened against the tension of the spring by swinging the handle 5| to the right in Figure 1. An overflow pipe 54 leads downwardly through the bottom 46 of the water chamber from a substantial distance above said bottom, and its lower end connects with the drain pipe 41 below the valve 43, whereby the cabinet may be given a preliminary heating by delivering a supply of hot water into the chamber 55 until it overflows through pipe 54. After the cabinet has been warmed, this water may bedraine'd away by opening the valve at 48. Hot water may be delivered into thecabinet by adjusting the mixing valve 32 to admit only hot water, and
opening the valve 35 to deliver this water directly into the chamber 55 through a short pipe 60 (Figure After the cabinet has been pre-warmed, the hood is swung backwardly and the patient placed in position on the bed slats I0. The hood is then closed, wh'ereupon the patient will ordinarily be given a treatment for the purpose of eliminating toxins and increasing the general circulation.
For administering the horizontal spray, a perforate pipe 62 is secured to one of the upper panels I3. It extends longitudinally along the under surface of the panel and is provided with multiple apertures adapted to deliver a spray over the body of the patient. A supply pipe leads from the header 34, (and the valve associated with the handle 38), rearwardly across the cabinet, and upwardly along the rear side of the base portion to a flexible hose connection 64 which connects the pipe 03 with an extension 65 mounted on the hood.
This extension 65 preferably extends through the wall of the hood near its base and then arouately along the inner surface of the hood to the spray pipe 62. The flexible joint provided by the short length of hose 64 allows the hoodxto swing upwardly and rearwardly on its hinge I5 carrying with it the extension or section 65 of the spray supply pipe. i
A similar pipe 68 leads rearwardly from the header 34, with its supply controlled by the valve associated with the handle 36. This pipe 68 also extends upwardlyat the rear of the cabinet and is connected by a flexible joint 69 with an extension I0 secured to the wall of the hood in the same manner as above described with reference to the extension 65.
The upper end of the pipe I0 connects with a longitudinally extending header I5 leading to chambered valve supporting blocks or socket members "I6, the cavities 11 of which are supplied with water from the header pipe I5 through ports 18 (Figure 6). spherically rounded valve supporting members or balls 80 are mounted for universal oscillation in the sockets of the members I6, with equatorial portions exposed in the cavities 11, whereby water may be delivered through a port 83in each ball to a bore 84, into the enlarged inner end of which the shank 85 of a nozzle head 86 may be screwed. Each nozzle head is adapted to receive interchangeable nozzle plates 87, (Figures 6 and '7), or 88, (Figure 8), these nozzle plates being secured to the nozzle head by coupling collars 89.
The ball is secured in its socket by a cap plate 90 and its outer portion is exposed through an aperture 9I in the associated panel I3 and provided with an outwardly projecting tubular stud 92 through which a valve stem 93 extends.
The valve stem 93 is of less diameter than the bore 84 in the ball 80. It has an intermediate portion threaded into the ball, and its inner end is reduced in diameter and provided with a valve 94 which seats on the nozzle head 86 around its central aperture 95.
While the ball 80 is allowed to freely oscillate in its socket, it is provided with a stop pin I00 loosely engaged between flanges IOI projecting inwardly from one wall of the cavity 11, whereby the ball is prevented from rotating when the valve stem 93 is being rotated to open or close the valve 94.
Means associated with the same source of water supply are provided for subjecting the spine of a patient to multiple jets directed upwardly through the bed upon which the patient reclines. It is frequently desirable that these jets be delivered against the spine of a patient while the patient is reclining on his back in order to bring about relaxation or stimulation of the spinal nerves according to the temperature and pressure of the water. To accomplish this I have mounted a pipe I05 along the under side of that portion of the bed which supports the body of the patient, and this pipe is provided with multiple nozzle jet apertures I06 adapted for delivery of impact jets upwardly through a longitudinal slot I01 in the bed. The pipe I05 may be supplied with water from the header 34 through a valve controlled by the handle 31 and a feed pipe III! leading inwardly to the nozzle pipe I 05,
For vapor bath treatments I employ an ordinary vapor generator I I5, which is preferably located outside of the cabinet and connected to a perforate pipe II6 which extends longitudinally in the base portion of the cabinet underneath a deflector plate I I1, one end of which is interposed between the pipe H6 and the perforate pipe I05, through which impact jets are delivered through the bed slot I01.
In the operation of my improved cabinet the hood is closed and the cabinet heated generally, either by'the electric generator indicated at H5 or by delivering hot water from any source through the pipe 60 into the pan underneath the bed. After a short period the valve 48 may be opened and this hot water drained away. Thereupon the hood may be opened to admit the patient and then closed and the ordinary spray and vapor bath treatments administered. If impact treatments are desired, the patient is placed upon his back with his spinal portion covering the slot I 0! in the bed, whereupon the valve at 31 is opened to' deliver the impact jets from pipe I05 through said slot I 01. Concurrently the valve at 36 may be opened to deliver water from the same source of supply through the pipe I0 and the header I5 to the dirigible nozzles 86, and thereby direct impact jets for local treatment of inflamed portions of the body, these portions and the direction of the jets being observed through the windows I4. When the treatments have been completed, all the valves are closed and the hood lifted and swung backwardly to release the patient. Thereupon, with all the valves closed, water will be permitted to drain from the pipes into the pan through drain apertures I20 located at the low points in the respective pipes.
Vapor bath cabinets equipped with spray pipes and means for giving vapor bath treatments are quite common in the art, but I believe I am the first to provide such cabinets with means for giving localized treatments by means of impact jets and spinal treatments by means of similar jets administered either for therapeutic purposes or for purposes of diversion while inflamed or swollen parts are being specially treated. I believe I am also the first to provide means whereby dirigible impact nozzles may be mounted within the cabinet and connected with an interior source of water supply in such a manner that the jets may be delivered and directed against any desired portion of the body of the patient by exterior manipulation of a valve stem, which is free for adjustment, unhampered by water supply connections.
It will be noted that the drain apertures I20 are located in union fittings I2I. In Figure 9, a modified form of fitting is illustrated, in which a tubular water actuated slideyalveis'mounted in a position to close the aperture I when water is flowing through the pipe. The outlet end of the valve is crossed by a flat bar I24 and the inlet end of the fitting is crossed by a bar I25. A coiled tension spring has its respective ends secured to these bars and normally holds the slide valve retracted from the drain port I20. But when water is being delivered through the pipe its pressure upon the valve cross bar I24 pushes the valve into a position closing the drain port I 29. As soon as water delivery ceases the spring retracts the valve and allows the pipe to drain.
In Figure 12 I have illustrated a modified form of dirigible nozzle 86a, controlled by a blunt needle valve 94a and provided with a Water distributing head 87a, which, when retracted from the port, will allow Water delivery in a solid stream, but when positioned in, or close to, the port will cause deliveries in spray form. In this construction, the nozzle head has its inlet port provided with a socketed fitting 76a in which a ported ball 80a is seated, this ball having a ported arm I28 coupled to the supply pipe 15a. The valve 94a has a stem 93a threaded in the noZZle head I30, and the latter is connected with the housing Wall I3a by a flexible diaphragm I3I closing the aperture 9Ia in the housing.
