NEEDLE-SPRAY AND SHOWER BATH.
SPECIFICATION forming part of Letters Patent No; 430,257, dated June 1 7, 1890.
Application filed December 7, 1889. Serial No. 332,917. (No modelJ zen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Needle-Spray and Shower Baths, and the following is declared to be a description of the same.
Shower-baths and needle-spray baths have been made in which there is an inclosure or case containing the shower at the top, and pipes around the interior of the case curved to the arc of about three-quarters of a circle, and perforated upon the inner sides of such pipes for the fine sprays or jets of water to pass through. In baths of this kind difficulty has arisen from the perforated pipes projecting inwardly from the surface of the casing and contracting the space allowed for the person that is taking the shower-bath, and besides this such pipes are difficult to keep in a clean and polished condition, especially upon the outer surfaces of the pipes contiguous to the inner surfaces of the sheet- -metal case. Besides this, if the pipes are made small to occupy less space, it is difficult to bore fine holes into suchsmall pipes where two or more ranges of holes are provided, because such' holes are necessarily bored perpendicular to the surface of the pipe, and with small pipes the jets are often directed upwardly and downwardly at too great an inclination, and another difticultyis experienced in the ordinary shower from the water dripping from the jet-tubes for a considerable period of time after the supply has been shut oif. This results from the atmosphere retaining the water within theshower-bath head, because there is no opening through which air can easily enter and allow the water to continue to descend until it all passes out from the shower-bath head.
My present improvements are intended to obviate all of these difficulties, and I combine with the inclosing-case spray-tubes, the convex surfaces of which are segments of a sufficiently-large-sized pipe to allow for the insertion of the jet-holes in the proper positions and angles, and such pipes have fiat backs that lie closely against the interior surface of the sheet-metal casing, so that not only the surfaces of the tubes can be kept in a polished condition, but access is given easily to all portions of the inclosing-case that are visible, and the fiat-back tubes occupy but little space and do not project sufficiently from the sheet-metal casing to contract the space for the bather or to obstruct the movements of the arms of the person, and to remove the difficulty arising from the dripping of the water from the shower after the supply has been cut off I introduce an air-vent in the form of a central tube rising sufficiently high to admit air into the shower-bath head after the supply has been cut 0%, so that the water may continue to descend freely until it all runs out from the jet-tubes or nipples, an dthis air-tube forms a central j et-tube when the water is turned on.
In the drawings, Figure 1 is a perspective view showing my improvements combined with a bath-tub. Fig. 2 is an elevation and partial section through one of the spray-tubes and its coupling. Fig. 3 is a sectional plan at one end of the spray-tube, Fig. 2; and Fig. 4 is a cross-section of the spray-tube. Fig. 5 is a cross-section through the shower, and Fig. 6 is a cross-section through the disk and one jet tube or tip.
A represents the bathtub, B, its case; C, the wainscoting of a room; D, the hood upon one end of the bathtub casing. A waste and overflow at 1 and hot and cold water cocks at 2 are provided for the equipment of the bath. The cocks 2 may be of any desired number and operate hot and cold water, the showerspray tubes, a mixing-column, &c.', as is com mon in apparatus heretofore employed by me.
WVithin the hood D, I provide a sheet-metal case D, which is circular and about twothirds of the circumference of a circle. The needle-bath is composed of the spray-tubes a b c, of which the three shown, or more, may be employed, and these'tubes are made to conform closely to the contour of the sheet-metal case D. These tubes, as shown in cross-section, Fig. 4, are approximately a half-circle or ellipse in which the back 3 is flat and imperforate, and the front 4 is convex and perforated with small holes bored on radial lines for the discharge of the water to form the spray. The flat back 3 touches the case D.
Because of the great convexity of the front 4 the holes bored through the same upon radial lines discharge the water at slight angles, so that a sufficient spray is directed against the bather. Each end of the tubes a b c is closed by an ornamental plug (1, and screw-bolts d are employed, that pass through the metal case D into the plugs 61 to connect and support the ends of said tubes.
At the center of each tube a b c is a sleeve eand short pipe e, into which said tube is secured and opens. The pipe e is screwthreaded and passes through the sheet-metal case D, and it is connected to T-couplings upon the vertical supply-pipe E, preferably by the coupling f, having right and left hand threads. The screw-collar h, around the pipe e and the washer 1', are employed to clamp the parts to the case D.
Above the tube 0 and its connection with the pipe E there is a coupling (see dotted lines, Fig. 1) and pipe to supply water through the upper part of the pipe E to the shower F. The pipe E is closed below the said coupling that is, between it and the connection to the tube a. I purpose connecting the pipe k with one of the cooks 2 and the devices at such place employed to regulate the supply of water.
The shower F is composed of the sheetmetal case I, the central tube m, the disk '27,, and the nozzle 0, and the jet tubes or tips 7'. The case Z is of any desired shape, and said case and the tube m are connected to the elbow of the horizontal tube E. The metal disk n has a flanged edge that sits snugly within the rim of the case Z and forms almost a water-tight joint, and this disk is sufficiently thick for screw-threads to be cut in the holes that receive the tapering jet tubes or tips 7', which are screwed into said disk. The nozzle 0 passes through a central I opening in the disk at, and screws into the lower end of the tube m to secure the disk n in place. I
In the central tube m are several ,perforations 5, to permit water to pass from said tube into the case lfor the shower. These perforations 5 are near the upper end of the nozzle 0. When the water is turned on, it
flows from both the nozzle 0 and jets T; but when turned off it continues to run from the jets 1' until the case is empty, because air passes up the nozzle 0 through the openings 5 into the case Z to replace the outgoing water, and thus prevent the after dripping,
which is so objectionable in showers heretofore constructed.
The parts of my needle-spray and shower are to be polished, burnished, or plated, and can afterward be assembled or put together, and all parts are easy of access, or can be taken apart for cleaning, and said needle spray and shower with the external case or hood are adapted for use with a bath-tub or with a floor slab or tray to receive the water.
I claim as my invention 1. The combination, in a needle-spray and shower bath with a sheet-metal case, of bent tubes that are half elliptical or circular in cross-section and perforated on the convex face, connections to said tubes passing through the metal lining to the source of water-supply, a pipe to the shower connected to the same water-supply, and a removable disk and perforated central tube and threaded j ettubes to the shower, substantially as set forth.
2. The combination, with a sheet-metal case and the water-supply pipe and couplings, of a tube having a flat back and convex half elliptical or circular perforated face, plugs d at the ends of such tubes, bolts (1' for securing such ends to the case,-the central sleeves e and pipes e, and the collars h and Washers 'i, substantially as set forth.
3. The combination, with a case D and the water-supply pipe and couplings, of spraytubes having fiat backs and convex half elliptical or circular perforated faces and the end pieces to such pipes, and the screws passing through the case into such end pieces for securing the tubes in place, substantially as and for the purposes set forth.
4. The combination, in a needle-spray and shower bath, with a sheet-metal case and the 9 a water-supply pipes and couplings, of the sheetmetal case 1, the central perforated tube m, the flanged metal disk 01, the nozzle 0, and the threaded jet tubes or tips r, substantially as set forth.
5. The combination, in a shower-bath, with a case Z and disk at, of a central tube m,having perforations, the plug and tube 0, rising within the tube m and forming an air-inlet, substantially as and for the purposes set forth.
