A packing Fig. 3 is a fragmentary, vertical, sectional view nut 33 surrounds the plunger 3| below the guidshowing the position of the piston at the start of `ing sleeve and is threaded on the latter.

its downward stroke; A piston 3| is movable in the sleeve 26, and 55 55 the lower end of the plunger 3| is threaded in the upper end of said piston, there being a nut 35 for locking the plunger in fixed position with respect to the piston. By loosening said nut, the length of the stroke of the plunger may be varied.

The piston 34 is provided near its upper end with a peripheral recess 36, there being a transverse duct 31 extending from said peripheral recess to a central, longitudinal duct 38. The latter duct communicates with an enlarged chamber 39 for a ball valve 40, said ball being normally held in closing position with respect to the lower end of the duct 38 by a spring 4|, the lower end of the spring being supported by a nut 42 having an aperture 43 therein.

In the lower end of the sleeve 26 is a chamber 44 for a ball valve 45. Said chamber communicates with the soap-ejecting nozzle I3. A spring 46 within said chamber normally holds the ball valve 45 in closing position. The upper end of the chamber 44 above the valve communicates with an enlarged soap measuring chamber 41,

there being a spring 48 disposed within said chamber against which the piston is adapted to act.

Above the partition I1 the sleeve 26 is formed with a port 49 which permits soap from the soap reservoir 50 to ow into the soap measuring charnber 41 when the piston is in the position of Fig. l to expose said port. Near its upper end the sleeve 26 is formed with over-flow ports 5| for a purpose to be hereinafter described.

To ll the device with soap the cap 29 is unthreaded to permit Withdrawal of the plunger and piston. Liquid soap may then be poured into the sleeve 26. Said soap will rst ll the soap measuring chamber 41 and will then over-now thru the port 49 and the over-flow ports 5| into the soap storage chamber 50. It is desirable to fill said chamber 50 to a level beneath the overflow ports 5|, as shown in the drawing, so that a certain amount of air is present in the upper portion of the casing. The piston is then replaced in the sleeve and the nut 29 threaded in place.

In use, the device is held over the patrons head in the usual manner, the tube 23 being connected to a suitable supply of water. When the water is turned on, it will flow thru said tube into the conduit 20 and into the chamber below the partition I1. The water will then emerge in the form of a spray from the apertures |0 of the "Water spray plate 9. After the patrons head has been suciently moistened, the water may be shut oft' and the plunger 3| depressed to cause ejection of a supply of soap from the nozzle |3. Before the plunger is depressed, the piston and valves are in the position shown in Fig. l, the

soap measuring chamber 41 being lled with liquid soap. When the piston has been moved sufficiently far to close the port 49, the parts will be in the position shown in Fig. 3, with the ball valve 45 still in closing position. Upon further movement, however, enough pressure will be created on the soap to cause opening of the ball valve 45 against the'tension of the spring 46, as shown in Fig. '4. 'I'his will necessarily cause ejection of soap. After soap has been ejected, the spring 48 `will cause automatic return of the plunger to normal position. However, said action will set up a vacuum in the soap `measuring chamber, and ordinarily this vacuum would retard the return of the piston. To eliminate this trouble, an automatic air intake has been provided. When this vacuum is created as the plunger is being returned, the vacuum will cause opening of the ball valve 49, as shown in Fig. 5. This will admit air from the peripheral recess 36 thru the transverse port 31, longitudinal port 36, and chamber 39 to break the vacuum within the soap measuring chamber 41 and thereby permit quick return of the plunger and piston to normal position. The peripheral recess 36 receives its supply of air thru leakage along the side of the piston from the space thereabove, and the air is supplied to said space from the air above the soap level in the soap chamber thru the medium of the ports 5|.

As before mentioned, adjustment of the length of the stroke of the plunger may be readily effected by loosening of the nut 35 and turning of the plunger one way or the other, as desired. This will permit measuring of theamount of soap to be discharged.

As the soap is discharged from the nozzle I3. if the end of said nozzle were in contact with the plate 9, soap would be likely to contact the plate and flow over the surface thereof to clog the Water apertures. Accordingly, the nozzle is so formed as to project from the central depression I2 to eliminate this possibility.

As in the application of F. E. Pearl, before mentioned, it will be seen that the water conduit 29 first passes thru the soap storage chamber to warm the latter so that it will be at such temperature as to not subject the patron to the discomfort of temperature differences between the soap and water. Furthermore, this warming of the soap tends to permit free flow thereof.

From the above it may readily be seen that a. very positive and effective means has been provided for forcibly ejecting soap from a water spray head, and it may further be seen that the action of the piston is positive, even in the return direction, due to the provision of means for breaking the vacuum therein.

Altho only one form of the invention has been shown and described, it is obvious that various changes and modifications may be made without departing from the spirit of the invention; and it is to be understood that all such changes are contemplated as may come within the scope of the claims.
