2 Claims.

This invention relates to a spray device, particularly of the type used as an adjunct to a wash basin for massaging and shampooing purposes, the main object of my invention being to enable a unitary device of this class to operatively supply a spray either for washing a head of hair, for example, within the basin, or for cleaning out the clogged drain of the basin when necessary.

Most spray devices comprise a tube leading from a faucet, and a hollow spray head suitably connected thereto. In the operation of devices of this class for, let us say, shampooing purposes, it frequently becomes necessary, during the course of the shampooing operation, to flush out the drain pipe of the basin and thereby remove therefrom accumulated hair or other obstructing elements which cause a backing up of water to the inconvenience of the operator and the discomfiture of the person being treated. The common practice is to disconnect the spray head from the tube, and attach to the latter a hollow water flusher which is placed over the drain opening, and the water turned on. This is not only troublesome and time-consuming, but obviously constitutes an annoying delay to a person required to wait, with wet or lathered hair, until the flushing operation is completed. And furthermore, with the use of the hollow water flusher superimposed upon the floor of the basin and over the drain opening, not only is the water apt to seep or squirt out from the sides, but the pressure thereof not sufficient, due to the diffused spray, to efficiently clear a clogged drain pipe. To overcome these disadvantages, I have conceived this invention which comprises a unitary device capable of supplying a spray not only for shampooing purposes, but also for effective and leakproof drain-flushing. And in one form of my invention it is my object to obtain these results Without the necessity of separately adding an independent drain flusher,-the accomplishment of which is effected by employing a water injector operatively insertible into the drain pipe, and retractible into the spray head when the device is to be used for shampooing purposes.

Another object of my invention is to enable a spray and massage disc to be detachably secured to the spray head in such manner as to permit a ready replacement thereof, a quick detachment of the disc when the drain flusher is to be employed, and a water-tight engagement of the disc with the spray head.

Still another object of this invention is to enable the spray head to be readily detached from the tube for cleaning thereof, or for its manipulation as a dry massaging device.

And a further object of my invention is to enable a protective spray shield to be readily removed from its operative position during the mas- (Cl. 15-405) saging operation without detaching it from the device.

Other objects, features and advantages will appear from the drawing and the description hereinafter given.

Referring to the drawing,

Figure 1 is a central vertical section of the device constituting one form of my invention, showing the spray and massage disc in place.

Figure 2 is a central vertical section of the device of Figure 1, with the spray and massage disc removed, and one form of drain flusher operatively in position.

Figure 3 is a central vertical section of another form of my invention showing a retractible drain drain-flusher assembly of Figures 3 and 4, showing the bayonet slot and pin for effecting the operative movement of the retractible unit, and

Figure 6 illustrates the spray device having mounted thereon a rubber shield, the dot-dash lines representing the position of the shield flapped back into its inoperative position.

In the drawing, the spray head I0 contains the casing I I having at the top thereof the hollow inwardly extending nipple or nozzle l2, the latter preferably though not necessarily being integral with the fitting I3 with which the said casing is in threaded engagement,the fitting l3 being attached to a suitable hose or tube connected to the faucet of a basin. The body of the casing preferably contains an annular recessed portion I 4 for v gripping purposes. In threaded engagement with the outer lateral surface of the bottom of the casing is the-flanged ferrule l5, the flange Hi thereof being in spaced relation to the bottom flange ll of the casing. Within the space between said flanges i6 and I1 is clamped the peripheral portion of the spray and massage disc l8.

It will thus be seen that the device so assembled, and particularly as shown in Figure 1, constitutes a spraying and massaging apparatus of simple construction, and yet thoroughly effective for its purpose. The nozzle l2, extending into the casing, causes a concentrated stream of water to be operatively directed upon the disc I8. By simply tightening the ferrule 16 on to the casing when the disc I8 is in place, a thorough sealing will be effected, inasmuch as the water can only leak out by following a tortuous path around the peripheral surface of the disc' in compressed engagement with the flanges I6 and I1. Should it be desired to remove the disc, either to replace it with a new one, or to clean the interior of the casing, or to attach the drainfiushing means (which will be hereinafter described), all that need be done is to unscrew the ferrule l5 and' the disc detached therefrom. This arrangement has the further advantage over many types of spray heads commonly employed in that the entire head need not be replaced upon a wearing out of the disc l8 or the massaging fingers l9 thereof, as the disc is an independent, replaceable unit. And by detaching the entire spray head It] from the fitting I3, the head can be employed for dry massaging purposes, in a manner that is self-evident.

In applying this structure for clearing a clogged drain of the basin in conjunction with which it is used, the disc I3 is removed as aforesaid, and the tubular plug or injector 20 is slidably mounted over the lower reduced portion of the nozzle I2 until it comes into abutment with the shoulder 2! near the top of the spray head, the plug in such position extending below the bottom opening 22 of the chamber. The said plug is preferably slightly tapered, and made of rubber or some other suitable somewhat yieldable material; and the axial hole 23 terminates preferably in a constricted outlet E i. as shown. The plug is then inserted into the drain opening, the tapered lateral side thereof enabling it to be snugly fitted into pipes of slightly different diameters. When the water is turned on, a concentrated stream will be directed into the drain to dislodge and force down obstructing particles; Inasmuch as the plug 255' fits snugly into the drain pipe, no water can seep therethrough back into the basin. When the drain has been cleared, the plug Zil can be readily detached from the nozzle I2, and the disc 58 re- 35" placedto enable the operator to continue his shampooing task.

, In order to obviate the necessity of attaching a separate drain-clearing element to the spray head, the modification of my invention shown in Figures 3, 4 and 5 can be employed. Here the spray head is the same as that of Figure 1, butthe nozzle 25 is somewhat longer, extending. almost to the surface of the disc 26, and

, contains the bayonet slot 21 adapted to operatively accommodate the pin 28, affixed to the upper portion of the sleeve 29 which is slidably mounted over said nozzle. The lower reduced portion of the sleeve has mounted thereover the I, conical rubber. plug element 3!] adapted for op- 50 erativeinsertion into a drain pipe in the mannerhereinabove referred to.

Normally, when the device is being used for shampooing purposes, the drain flushing elements comprising the sleeve 29 and plug 36 are in their retracted positions wholly within the casing, the pin 28 being within the notch 3i to hold the sleeve against vertical movement. It

will be noticed that in this position the bottom.

of the plug 3!! is in spaced relation to the disc 26,,thereby not constituting an obstruction to thefiow of water from the nozzle to the holes in the said disc.

When it is desired to operatively employ the drain-flushing elements, the disc 26 is removed 65 in themanner aforesaid, the sleeve 29 turned to disengage the pin 28 from the notch 3.! and then lowered and turned again in the oposite position to bring the pin into thenotch 32. In this projected position the sleeve will be held 1 against vertical movement, thereby enabling the V plug 30 to be operatively inserted into the drain to flush same in the manneralready described.

Should it be desired to detach the spray head from the fitting 33, the sleeve 29- is turned, when in its lowermost position, to bring the pin 28 into the open-ended slot 34 which extends to the bottom surface of the nozzle 25, in this way 5 enabling the sleeve to be disengaged from the nozzle. Thereafter the casing of the spray head is unscrewed from the nozzle and readily detached therefrom. It is obvious that this form of my invention containing a detachable spray 10 discand a retractible drain fiusher in a unitary device is simple in structure, yet of considerable convenience particularly to barbers and hairdressers.

It is frequently necessary to confine the spray 15 by the use of a shield, generally made of rubber and detachably mounted on the spray head. As a part of my invention I employ the reversible rubber shield 35 shown in Figure 6 which is suitably mounted upon the ferrule 36. Preferably 20 the ferrule may have an annular depression into which fits the bead 31 forming the upper periphcry of the shield. The shield, being thin and flexible, can be fiapped back upon the spray head casing, the shape of the shield being made to con- 25 form to that of the casing, as shown. The operator can therefore readily grasp the device even with the shield in its inoperative position.

It is of course understood that the various embodiments above described and shown in the 30.

drawing are illustrative of my invention and not employed by way of limitation, inasmuch as numerous changes and modifications may be made within the scope of the appended claims without departing from the spirit of this invention. 35"
