s. ISENBERG SPRAY HEAD Filed March 2, 1942 Patent ed July 27, 1943 SPRAY HEAD 3 Stanley Ise'nberg, Qhicago, I ll.:

Application March 2, 1942, S nris saozsff 3 Claims. :(o1'.-1 5 128) i Thi invention relates to improvements in bath and shampoo sprays. One object is toprovide a liquid spray including a spray head that may be J provided with a massage brush that cooperates with the spray proper'in washing the hair and i scalp and that is also ideal for body' massage or device that is shaped to snugly fit the hand ofthe operator and that in use readily adapts itself 1) down. A further object is to, provide a spray adapted toreceive the terminal "flangej of said 'coupling, The base of the-ybell:shapedhead is wi'dened'somewhatto form th bufferrin'gt and along its i'nner wall it is formed'with an'annu'lar recess l adapted to receivethe inwardly bent fiangeiof the spray disc '8 formed with a plurality'o-f small perforations 9 to spray the water.

The base of the bell is formed upon its lowermost face with. apl'urality of bristles iii spaced apart and extending completel thereabout toform a massage brush. Inwashing or rinsing the hair this brush may serve to spread the hair topermit freer access of the water .to the scalp andrto the inner ends of the strands of hair.

the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the claims and illustrated in the accompanying drawing, and in which- Fig.1. is a top plan view of a spray head constructed according to the present invention.

Fig. 2 is an inverted plan view of Fig. 1, the perforated disc being omitted.

Fig. 3 is a central vertical sectional view throughFig. 1 taken on the line 33 thereof and showing the perforated disc.-

Fig. 41s a view similar to Fig. 3, but of a slightly modified form of spray head.

Fig. 5 is a view in elevation of a further slightly modified form of spray head.

Fig. 6 is a central vertical sectional view.

through Fig, 5 taken on theline' 6-5. d

Fig. '7 is a vview similar to Fig. 4 but. of a further slightly modified form of the device,

' and,

Figs; 3 and 9 are fragmentary sectionalviews illustrating further slight structural modifications.

Litre reference-characters denote corresponding parts throughout the severalviews.

Referring now to Figs. '1, 2 and 3 of the drawing, thespray head includes a substantially bell shaped resilient or all rubber head i, the crown or topmost portion thereof being materially thickened and havinga perforation 4 to receive the coupling 2 for the rubber tube (not shown),

said crown being formed alsowith the annular recess 3 opening into said perforation and Extending radially from the central perforation 4 almost or quite to the recess! are, the

spaced ribs I I of material depth, the lowermost tread face of each rib clearly shownin Fig. 2 1 being somewhat rounded and smooth, said ribs terminating contiguous to said disc 8. The ribs H materially strengthen the head and prevent its collapse or expansion whenpressure is applied to the crown thereof. When external pres sure is applied the head may be moved inwardly but slightly when the-ribswill ride against the disc 8 which action will efi'ectually prevent distortion. In assemblingthe-spray head at the factory the disc 8 is introduced into the. head as the latter is spread at its mouth mechanically,

as by a jig, the disc coming in contact with-the ribs and being-moved or slid thereby into engaging position with the head recess L' It will be noted that the wall of the base of the head is of material thicknessto permit it to resist pressure without losing its shape when gripped firmly; Referring now to Fig. 4 the head is provided with a central perforation through which the coupling 20. extends, the terminal flange 511 being, disposed inside the head about said perforation. This head is formed with a' smooth inner wall without ribs. Referring now to Figs. 5 and 6 the head lb terminates in an annular flange or shield l2 disposed in advance of or below the disc 8 tov prevent lateral splash of the spray in using the spray head.

Referring now toFig. '7 the rubber head lc snugly receives and carries a' non-rubber hollow j bod l3 formed-with a stern .14 that extends through thehead crown to receive the rubber tube, saidnon-rubber body being formed also with an annular rib l5 that seats in the recess Ia I of said rubber head, the base of said body being .1 formed with perforations to spray the fluid, said al1 rubber head being provided upon its base with bristles l0 disposed outwardly or below and about said perforated body base.

j Referring now to Fig. 8 the all rubber head id is formed with an inner annular shoulder I6 upon which thefperforated disc 8 is received, said disc fitting. snugly within the head upon said shoulder and by said resilient head being frictionally retained in this operative'position. The head id .is formed with bristles l0 upon the lower face of its base, saidbristles being spaced about and in'lower spacedrelation; to said'disc. Referring now to Fig. 9 the alllrubber head is V is formed with an inner annular shoulder l6 and thereabove with ribs II that extend from the crown of said head almost but not-quite to said shoulder 16 so that a space is provided between said shoulder and each rib wherein said," disc 'flange is received and frictionally retained.

The novel features and the operations of this device .will be apparent from the foregoing de- 2. In a' liquid spray device, a bell-shaped head formed of rubber'or sirnilar material having a small perforation in its, crown anda recess registering with'isaidperforation "to receive a flanged coupling; a perforated disc carried by said head, bristles integral with said head disposed about said disc in a plane parallel to and beyond said disc, and spaced'ribs having narrow .smooth treads running from said crown perforation to said disc;

V3.'In a liquid spray device, aresilient bell scription. While the device has been shown and V the structure described in detail it is obvious that this is not to be considered limited to the exact form disclosed and that changes may be made therein within the scope of;what is claimed .stfithout departing from the. spirit of the in veri ion.

, Whatisclaimed v shaped head," an annular shoulder formed inwardly of said head, spaced ribs in said head terminating contiguous to said shoulder, a perforated disc having a era-extensive peripheral flange 'received andfrictionally retained between said shoulder ,and ribs, and bristles integral with 'sa idhead disposed about said disc in a plane parallel to andbeyondsaid disc. 1
