' SHOWER HEAD Filed Jan. 4, 1950 INVENTOR. ELc/zard fitras'smam drilled or otherwise formed therein, and is sufficiently large at its inner end substantially to encompass the aperture in the ball l2 in any angular position of adjustment of the spray head on the ball. The inner end wall of this recess is bevelled or chamfered, as at 18, to fit against the ball 12 and is preferably provided with an annular recess to receive a suitable packing material and which may take the form of a washer is to ensure a watertight engagement of the core member .M with'the ball l2 in. anyand all positions of adjustment of the core member on the ball during its change of position.

The core member 14 is thus secured to the ball 15 I2 by a suitable socket collar 20 having anin wardly extending annular flange or lip 2l having an opening of a size to pass over the outer end of coupling H but too small to pass over the ball l2 thereof, as indicated in Figs..; 1 and 2,

and therefore engaging the same. The collar 20 is internally threaded in its outer end portion and isadapted to thread onto the inner end of the core member M, as indicated, and thus to clamp the two together. The outer surface of collar 20 is preferably roughened or knurled, asby the longitudinal small grooves 22 shown in Fig. 1 which gives it a good finger grip for suitably tightening and loosening the same, without the use of tools, to cause the core member efficiently to be pressed against and connected with the ball to provide a watertight connection and yet permit the head to be moved and adjusted angularly on the ball, the frictional contact between the core and ball permitting such movement and maintaining the core and head in any adjusted position. V

The outer surface of the coupling H is also preferably knurled by longitudinal grooves similar to lines or grooves 22 of the collar.

, The core member is thus directly connected with the ball joint., The core member is provided with apertures 23 in any desired number, preferably four, which may be drilled or formed through the'wall between the bottom of recess l1 and the space in advance of the end'section I5 aroundthe portion lfiand forming a. passage for water therethrough.

.The end section [5 or head of the core member l4, rigidly attached thereto and preferably integral therewith, is cylindrical, somewhat less in diameter than the exterior of the. .apertured portion of the member, has a relatively .wide and generally smooth peripheral .edge. 24 forming a cylindrical surface longitudinally parallel to the alxis of the memberandto the exterior of the said recessed portion of said member. This peripheral edge 24 of. the end section is provided with a plurality of tapered spray-stream-forming groovesor passages 25 extending longitudinally thereacross and spaced apart preferably equally, as indicated, all around the said edge. Said grooves may be triangular incross section, as indicated, or of other form, such as round, square or the like; arepreferably deepest and widest at their inner ends, that is, larger in cross section, and gradually taper and diminish in cross section to their outer ends, where, at the outer face of said section I5, they are relatively very small, preferablypin-point in size, as indicated in Fig. 6. Thus, needle-like spray streams may be produced if desired. As will be understood, the water to form the shower spray is ejected through these grooves 25, and .in order to complete the same, and to con- .fine the water theretoithe core member [4 is provided with an adjustable sleeve or collar '26 having an internally threaded portion 21 at its inner end adapted to thread on the outer externally threaded end of the core member l4, said collar 26 having an inturned, cylindrical, flat, ring-like flange or end sleeve portion 28 of substantial width and smooth-surfaced and of a size closely to fit the said peripheral cylindrical edge 24 of the spaced end section E5 of the core member Hi. -The. fit of "the ring; 28"00 the said peripheral edge '24 is such as to be substantially watertight but to be rotatable thereon and slid- "able longitudinally thereof in the rotation of the. threaded collar 26 by the hand. The collar also preferably grooved and smoothed outwardly on the inside, as at 29, and of slightly larger diameter than the threaded portion 21 and of thestream-adjusting ring, sleeve or collar 28, fora freer movement of the water. The outer end of the adjusting collar 26 is provided with a slight forwardlyprojecting ring portion 3| serving as a splash guard in case a jet or jets tend to spurt transversely due to small bits of dirt in the grooves or other temporary causes.

As thus constructed, the adjustment of the ring 28 longitudinally along the peripheral edge of end section [5 of the core member determines the size and character of the spray stream issu ing from the grooves 25. Thus, when the collar is out even with the outer face of the. end section I5, as indicated in dotted lines 3% in Fig. 2, the streams issue in a fine, needle-like spray. When the collar is farther back, for example as shown in full lines in Fig. 2, the individual streams are larger and the spray softer; When the collaris still farther back, the spray may become a generous soaking spray. In all positions of the collar the, issuing spray streamis comparatively of small diameter due to the axial parallelism of the contacting cylindrical surfaces 28 of the collar 26 and the periphery 2'4 of the section l5; and if the spray grooves extend across the head or section l5 parallel with the axis, of the shower head, the jets issue practically parallel thereto, though spreading outwardly somewhat as the jets try to escape from the uncovered portions of the grooves to form a slightly larger spray stream as a Whole.

It'is preferred, however, to provide a more divergent spray stream while still keeping it within suitable confines, such as the limits: of the bathtub and away from walls, window sills, bath;- room floors, and they like, and at the same time maintaining control of the individual streams or jets of thespray throughout their range of adjustment from fine to coarse and economizing in the amount of water used.

To accomplishthis, the spray grooves or pas: sages 25 extend across the peripheral edge 24 of the heador end section 15, each at a slight angle laterally to a longitudinal line there through parallel to the axis of the core member. Thus, in-Fig. 7, the line 35 may represent the medial longitudinal line through the groove 25 and parallel to the axis of the core, and the line 36 the medial line or axis of the'circumfera entially ofiset groove, 25, The angle 37 represents the lateral divergencereferred to of the groove -from a longitudinal line therethrough parallel to the axis of thev core. The extent of this angle 31 depends upon the divergence of the spray stream desired under the conditions prevailing. shower purposes and with substantially the'pro portions shown, with about 20 grooves provided For ordinary bath ire-the:heed na under tramarwcenuamnsean afigle' 33 "oi -2 to i5 de 'ees' hasbeen tEoundsafii's faetory to prdddce' a spray stream fl to winches iri'diafneter at 'fiveo'r si'x fet away f-romthe new zle; but other angles, greater or less, may be'iused if-desired and m'or e "o'r "less grooves; The gfiea'ter the' angle the largerthe crosssection ortne -spray stream away from the nozzle.

Such control of r the individual divergent streams is due to the relative longitudinal lmove ment of the co-operating' grooved and" cover members, with the grooves askew, as-explained, tothe'axis or movement, since the cover're'ma ins inwatertight contact with the surfaces at-the sides of or between thevgroovesand-confines the streams to the grooves whatever the relative longitudinal adjustment of the" two members may be. For this purpose the grooves maybe located in either member and the othermem berbe smooth, either member maybe relatively stationary and the other member longitudinally movable with respect thereto, andthe'relative longitudinal movement may be the result of the rotation of either member with respect to the other on a suitable threaded or likesupport' o"r' by the longitudinal sliding of either memberon or with respect-to the other without rota'tionv In all, however, the grooves ei'c tend at a-late'ral angle to thesaid longitudinal movement.
