the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a. spray apparatus used with bath tubs, and the principal objects of my invention are to provide a device of this class in which the spray-nozzle may be easily and quickly turned or adjusted in any desired position, and to maintain its position of adjustment without the aid of the user or without external support, and to provide a spray-nozzle which will project or throw a series of sprays vin directions different from each other, and

which may be directed to practically a common point, and further to provide a simple means of detachably mounting the bathspray in operative position.

With these and other objects in view, my invention consists in the various novel and peculiar arrangements and combinations of diii'erent parts of the apparatus, all as hereinafter fully described and then pointed out in the claims.

I have illustrated types of my invention in the accompanying drawings, wherein Figure 1 is a side view of a bath tub equipped with my improvements, one endy of the tub being broken away to show the fixture within the tub. Fig. 2 is a sideview of the clamp for detachably mounting the bath-spray upon the faucet or fixture of the tub. Fie' 3 is another view of the clamp for detachably securing the bath-spray in place, the clamp being adjusted in a position at right angles to that shown in Fig. 2. Figs. 4 and 5 are views of a modified form of the clamp for detachably securing the bath-spray in place upon the fixture, the

views of the clamp being taken at right an` gles to each other. Fig. 6 is an lenlarged view of one of the spray-nozzles shown in` Fig. 1, the nozzle being here shown as turned on its axis through a half circle to invert it, the dotted line position showing the nozzle as' adjusted in a downwardly pointing position. Fig.l 7 is a side view of a modltication ofthe bath-spray and shows -the nozzle supporting pipe,' which is of flexible metal, being made comparatively long and itself supportedby a clamp at its lower end, and the clamp being shown as attached to the vertical part of fa faucet. In this view the dotted lines show the spraynozzle in a different position of adjustment.

Fig. 8 is a side View of a modication of the pipe for supporting the spray-nozzle, the pipe here shown being a lflexible metal pipe having solid cylindrical walls as contradistinguished from the i corrugated ie-xible meta-l pipe shown in Fig. 7 In this View the dot-ted lines show the spray-nozzle as moved into a different adjustment. Fig. 9 is an enlarged front View of my improved spray-nozzle shown as detached. Fig. 10 is a horizontal sectional view of the spraynozzle shown inFig. 9, the plane of the view being indicated by line 10-10, Fig. 9. Fig. 11 is a central vertical sectional view of the spray-nozzle shown in Fig. 9. Fig. 12 is a diagrammatic view'showing the respective lengths of a pair of arc-shaped nozzles when used together upon the same pipe,

Referring to the drawings in which like numbers of reference designate like parts throughout, my improved spray-nozzle indicated by the numeral 1 is shown as constructed of sheet metal and is of an elongated shape made substantially in the form of an arc, and with the face thereof provided with a plurality of groups of sprayholes 2, 3 and l. The nozzles are hollow practically throughout, and the face thereof which bears the groups of spray-holes is made in a peculiar form, as indicated in the drawings, and so that each group of sprayholes or rose is in a different plane from that of the adjacent group or groups. For

example, assuming that the nozzle is set so that the plane containing thegroup of spray-holes 3, stands in a vertical plane, the

lplanes lcontaining the 'other two' groups 2 and 4, make an obtuse yangle with the said vertical plane, and lthe said planes contain-- as hereinafter described. The pu ose-of having the groups of spray-h oles t us arranged is to provide a plurality of spra s which comingv from diHerent points of t e elongated nozzle may converge and be thrown against practically a common polnt, thus reventing the sprayed water from being t irown beyond the sides of the bath tub. The length of the are form of the nozzle ma be made longer or shorter, as desired, an the angles between the planes containing the difl'erent groups of spray-holes may be varied to control in thedesired manner the direction of each spray' relative to the others, the face of the nozzle being bowed.

The back of the `spray-nozzle is provided with a tubular part 5, which its within the tubular end 6, of the nozzle-supporting pipe 8, the joint between the two parts 5 and 6, being a friction-joint for permitting the ready coupling and uncoupling of the parts and enabling the operator to rotate the nozzle on its support, thereby permitting him to adjust the arc-shaped nozzle at any angular position relative to its sup-port.` Thus it can be completely inverted vwhen desired, the

friction-joint of course being capable of holding the nozzle against dislodgment by the force of the water, the inverted position of the nozzle being shown in Fig. 6.

The pipe 8 both supports the nozzle and supplies the water thereto and this pipe is a flexible metal one and has such flexibility as not to require external support to give it the necessary rigidity to retain its position of adjustment, so that it can be liexed or bent by hand into any desired position in order to change the direction in which the sprays are thrown by the nozzle. This is an important feature of the invention, and it is carried out by means of a flexible metal pipe having the described capacity, and for this purpose I use either an ordinary corrugated flexible metal pipe, which is found as a commodity upon the market, or I use a cylindrical metal pipe having solid non-corrugated walls, and made of a suitable metal such as block-tin, which will permit of the pipe being readily flexed or bent by hand without much force, but at the same time has the described rigidity, that is to say, it will retain itself in the adjusted position without external support, a non-corrugated pipe for the nozzle of the kind described being sho-wn at 8b in Fig. 8.

In Figs. 1 to 6, inclusive, I show the iexible metal nozzle-supporting pipe 8, as connected with a rigid 'metal pipe 9, which is detacha-bly mounted in a clamp V10, which -is clamped to an ordinary faucet 11, of a bath-tub 12, the faucet 1l, being supplied in .the usual way with both hot and cold water, one of the supply-pipes of the faucet being indicated at 13. The rigid pipe 9, is provided n'ear its lower end with a tubular lateral extension 14 which has its Aoutside formed .with a'spiral rib 15, (see Fig. 5), and when the pipe 9, is mounted in vertical position in the clamp,- a rubber tube 16, is coupled between the nozzle of the faucet 11, and the ribbed extension 14, ofthe pipe 9,

so that when the faucet is opened water is.

supplied to the vertical pipe 9.y In Fig. 1 I show a pipe 9, as being provided with-a pair of my improved nozzles 1, each being at` tached to and supported by a flexible metal pipe 8, receiving the water from the pipe 9. This pipe 9, is provided with a cock 17, for cutting off the upper nozzle, and a similar cock 18, for cutting oif both nozzles when desired. In using a pair` of nozzles arranged one above the other, I prefer to make the lower nozzle longer than the upper one, as indicated in the diagrammatic View in Fig. 13, in order to give a greater spread to the spray, for the reason that the lower nozzle directs its sprays well within the conlines of the tub .without liability of throwing the spray beyond the sides thereof.

In the arrangement shown in Figs. 1 to 6, inclusive, the length of the flexible metal pipe 8, for supporting the spray-nozzles and j supplying water thereto should be suiiicient to permit of such pipe being readily flexed by lhand in any direction about the point of support of the pipe, so that the user can easily bend the pipe into whatever posil 4tion he may-desire in order to control the direction in which the sprays are thrown by the nozzle. In Fig. 1 the flexible pipe 8, of the upper nozzle is shown as adjusted in a Y substantially horizontal position, so that the vsprays will be thrown in arc-form when Viewed from the side, and as substantially indicated by the dotted lines, while` the iiexible pipe of the lower nozzle is bent downwardly so that the sprays from the lower nozzle are thrown more directly downdotted lines. In Fig. 6 the flexible pipe 8, of the spray-nozzle is shown as bent upwardly, which position may be desired when the nozzle is mounted at a very low point. The dotted line position in Fig. 6 shows the iiexible metal pipe as bent downwardly substantially on the order of theA lower nozzlevpipe in Fig. 1.

In Fig. 7 I show a construction in which the flexible metal pipe 8a, is made of Sullicient length to take the place of the rigid pipe, shown in Figs. 1 to 6, inclusive. In this construction the flexible pipe' 8", `is secured directly to the clamp 10, which is attached-to the depending vertical part of the faucet 11, and the lower end of the iiexible pipe' 8a, is provided with a smooth coupling-piece 19, over which is slipped one end of the rubber tube 20, the other end of such lwardly into the tub, as indicated by the tube being slipped over the end of the faucet 11, to connect the faucet with the flexible pipe, the rubber tube 20, being provided at each end with an enlarged couplingpiece 21. The flexible pipe 8 may be twisted in any direction about its vertical axis, as shown in the drawings, and it may also be bent or flexed laterally in the position desired, the dotted lines in Fig. 7 showing the pipe bent somewhat upwardly with the nozzle directed downwardly. In order to protect the hand of the user in manipulating the corrugated form of flexible pipe, I provide a hand-grip in the form of a sleeve 22, which is made of a Asoft material such as felt or leather.

In Fig. 8 I show the same form of construction as in Fig. 7, with the exception that the flexible pipe 8b has a smooth exterior, instead of a corrugated one. As hereinabove stated, this pipe maybe made of block-tin or a metal having the same capacity of flexibility and rigidity.

, It will thus be seen that by virtue of having the supporting-pipe of the nozzle made of a flexible metal having at the same time a certain degree of rigidity, as above pointed out, and having the spray-nozzle so mounted uponsuch a pipe that the nozzle may be turned on its axis into any adjustment thereon, I provide a device in which the spray-nozzle has,'what,I may term, universal capacity of adjustment. One of the important advantages in using a flexible pipe on the order of that described is, that all movable joints are dispensed with, and I am further able to use ordinary flexible metal pipe as found upon-the market.

The character of the flexible metal pipe which supports the spray-nozzle and permits of its universal adjustment is such as to readily admit of being bent, bowed or twisted by hand without breaking or rupturing, and at the same time has sufficient rigidity to maintain its position of adjustment without external support and without liability of being moved out of such adjustment by the pressure or fo-rce of the body of water passing through the pipe. This pipe may be repeatedly flexed and twisted without destroying it or incapacitating it in the performance of its function of providing a secure conduit for the passage of water under pressure and of remaining in its adjusted position without the aid of external support. j

The clamp 10, for detach'ablyy securing the rigid pipe 9, or the exible pipe 8, to the faucet 11, is provided with two pipe-receiving sockets 22 and 23 respectively, which are located at right angles to each other, the socket 23 in the end of the clamp'be'ing used to receive the pipe when mounted upon the horizontal part of the faucet 11, as indicated in Figs. 1, 2 and 3, respectively, while the other socket 22, is used for holding the pipe whenthe clamp is mounted upon the vertical part of the faucet 11, as indicated in Figs.v 3, 7 and 8.

The clamp shown in Figs. 1,2, 3,7 and 8, is composed of two similar members 24 and 25,

` the inner face of the respective members being formed with recesses 26 and 27, respectively, which form a socket for receiving the part of the faucet 11, on which the clamp is mounted. At another point on the inner faces of the clampin members are recesses 28 and 29 for formmg the socket 22, for holding thepipe, while atthe endofthe clamping members the 1 opposite inner faces of the kmembers arel recessedfat 30 and'31, respectively, to form the socket 23, for receiving the pipe. The set- screws 32 and 33, are provided at each end of the clamping members to bind them together, and a third set-screw 34, is arranged near ythe center of length'of the members as an additional means for clamping the members upon the faucet.

vIn Figs. 4 and 5 I show a modified form of the clamp and in which the clamp is composed of a single member, one end of which is formed with a ring 36, into the sides' of which are let a series of set-screws 37, which point toward the center of the circle, and the inner ends of which screws engage the part of the faucet 11, on which the clamp is mounted. From one side of the annular part or ring 36 projects a boss in which is formed laterally a socket 38, and in the end of this boss is formed another socket 39, running' at right angles to the socket 38, and the two sockets intersecting. A; setscrew 40, is let into the side of the boss so as' to coperate with either socket 38 or 3.9. When this clamp is secured to a vertical part of the faucet 11, as indicated in Fig. 4, the pipe 9, ofthe spray-device is inserted in the socket 38,' and' thevset-screw 40, holds it in the socket. When this clamp is mounted upon a horizontal part of the faucet 11, as shown in Fig. 5, the pipe 9, of the spraydevice is inserted in the end socket 39, and the set-screw 40, is turned down against the pipe so as to securely hold it in the socket.

In'the-operation of my improved spraydevice, it will be readily understood that the user of the device may before turning the Water on set the nozzlev in adesired position to spray a particular part of his body, by turning the nozzle on its1 point of support or iexing the supporting pipe, or both, and that after such adjustment of either or both of these parts, it is unnecessary for the user to hold any part of the apparatus with his where the lower nozzle is much elongate as it can be and' still directs its sprays Within the tub.l

Having thus described my' invention, what I claim and desire to secure by Letters Iatcnt is:

1. A bath-spray comprising a spray-nozzle and a pipe for supplying Waterl thereto, the said spray-nozzle being elongated and of considerable Width and having-its front face curved or bent to form it into a series of substantially flat plane surfaces forming angles witheach other and each flat surface being provided with a group of spray-holes, thev said groups of spray-holes being adapted to pro]ect their sprays at angles to each other but in a converging direction to confine the sprays within the'bath-tub, substan tially as ascribed.

2.v A bath-spray comprising a spray-noz zle and a pipe connected wlth said nozzle and supplying water thereto, the said spray- `nozzle being elongated and provided with a series of spaced roups vof spray-holes disposed substantial y in a vertical are form and each disposed in substantially a differcnt plane from the others, substantially as described. s

In testimony whereof I have hereunto set 30 my hand in the presence of the two subseribing Witnesses, l v
