7 Ciaims. (Cl. Z39- 1460) .This invention relates to an improved adjustable shower head.

It is an object of the present invention to provide a shower head which may be adjusted to vary the neness of spray emerging therefrom.

Another object of the invention is to provide an adjustable shower head capable of producing a multiplicity of cones of spray.

A further object of the invention is to provide an adjustable shower head of inherently simple and economical design. Y

A still further object of the invention is to provide improved means for adjusting the spraying elements of a shower head.

A yet further object of the invention is to provide an improved shower head which will resist clogging and is easily accessible for cleaning.

`Other objects and advantages of the present invention will become apparent from the following description as read in connection with the accompanying drawing.

In the drawing:

Fig. 1 is a cross-sectional elevation lof one embodiment of the invention;

Fig. 2 is a cross-sectional elevation taken about the line 2-2 of Fig. 1;

Fig. 3 is a cross-sectional view taken about the line 3-3 of Fig. 1;

Fig. 4 is an isometric exploded view ofthe retaining ring and a portion of the crankshaft employed in the aforesaid embodiment of the invention; h

Fig. 5 is an isometric view of one spray directing member'employed in the said embodiment of the invention.

vSimilar reference numerals indicate corresponding parts throughout the several views. Y

As shown in the accompanying drawing, one embodiment of the invention comprises a housing, generally designated by the numeral lil and provided with atthreaded end portion 11, adapted for engagement with a threaded coupling 12 forming part of a water outlet 13a having a spherical periphery 1.3. Said spherical periphery extends into the housing, as depicted in Figs. l and 2, where it is secured in slidable contact with a circular washer 14. With this arrangement, the housing may be moved in a wide variety of directions on the aforesaid spherical periphrey of the water outlet. Y

The washer 14 is disposed upon an annular shoulder 15 formed Within the housing, and covers annular groove 15a which receives a substantially circular retaining ring 16, such as is depicted in Fig. 4. As seen in this iigure and in Figs. 1 and 2, the retaining ring is not continuous and has a depending end portion 16a disposedthrough a suitable aperture 17 formed at the base of said annular groove 15, said retaining ring extending into an annular groove 18 formed on the periphery of a radially disposed crankshaft generally designated by the numeral i9. With this arrangement, the retaining ring biases the crankshaft against radial displacement with respect to the housing. t

atent O ice Vin thehousing, the crankshaft being rotatable within said channel. Ring Z1 serves to prevent undesirable slippage of the crankshaft and lalso prevents water leakage from within the housing. Y

The crankshaft is also provided with a circular eccentric 24, and a circular, eccentric pin 25 projecting from the face of eccentric Y24.

`An interior throat portion 26 is formed in the housing and slidably receives an outer spray directing member, generally designated by the numeral 27, which has a hollow, Vcylindrical interior 28 communicatingk with any stream of water which may emerge from the aforesaid outlet` 13a. Apertures 29 are formed in the wall of the said outer spray directing member, thereby permitting water to flow from the interior thereof into an expanded interior portion 30 of the housing 10.

The lower end of the outer spray directing member has a short, cylindrical'periphery 31 communicating with a peripheral portion 32 of frustro-conical form. A plurality of peripheral notches 33 are formed upon the said lower end of the outer spray directing member, said notches extending in the general direction'of the axis of said spray directing member and being inclined with rcspect to that axis, as depicted in Figs. 1, 2 and 5. When said spray directing member is in 4an open position such as that depicted in Fig. 1, these notches tend to accomplish a conical spray of any water which may emerge therethrough from the expanded interior portion 30 of the lhousing 10. t

As may be seen in Figs. 1, 2 and 5, the upper end of the outer spray directing member is provided with an aperture 34 which slidably receives circular eccentric 24.` When the crankshaft is rotated by means of handle Ztl, the outermost portion of the periphery of the'eccentric 24 will describe a circular path such as that indicated by the dotted lines designated by the numeral 35 in Fig. V2. As seen'in this figure, when the eccentric 24 is at its highest position in this path, the outer spray directing member is retracted within the housing so as to close its J EIt is noteworthy that since these peripheral notches may assume this `open position, they tend to resist clogging and are easily accessible for purposes of cleaning.

The foregoing embodiment of the invention is also provided with an inner spray Y,directing'memberg generally designated by the numeral 36. This inner spray directing member is slidably received within the outer spray,Y directing member and is concentric with respect thereto. The inner spray directing member has 1a hollow interior portion 37 communicating with any stream of waterV n Vemerglng from outlet 13a. Said inner spray directingV Y' member is also provided with apertures 38 communicating from said interior portion 37 v to the aforesaid expanded interior portion 30Vofthe housing.

As in the casev of the outer spray directing member, t

.the lowerend of the .inner spray directing member` has a short, cylindrical periphery 38a communicating with a peripheral portion 39 of frustro-conical form. A plu' rality of peripheral notches 40, extending in the same general direction as those of the outer spray directing member, are also formed upon the said lower end of the inner spra'y directing member-(see `Figsfl and-2).

When said inner spray directing memberris in an open position such as that shown in Fig. 1, the last-mentioned peripheral notches 40 tend to accomplish a conical spray of any water which may emerge therethrough from the expanded interior portion 30 of the housing 10, this conical spray being disposed within the conical spray produced by the outer spray directing member.

As may be seen in Figs. 1 and 2, the upper end of the inner spray directing member is provided with an aperture 41 which slidably receives the circular eccentric pin 25. This pin may also be seen inv Fig. 3; When the crankshaft is rotated by means of handle 20, the outermost portion of the periphery of the pin 25 will also describe a circular path such as that indicated by the dotted lines designated by the numeral 35 in Fig'. 2. As seen in this figure, when the pin 25 is at its highest position in this path, the inner spray directing member is retracted within the outer spray directing member so as to close the peripheral notches 40 by reason of the wall of the hollow cylindrical interior 28 of the outer spray directing member being in contact with the lower cylindrical periphery 38 of the inner spray directing member, said contact extending below the lowest portion of said peripheral notches 40. However, when the pin 25 is rotated to its lowest position, the inner spray directing member will assume the position depicted in Fig. 1, wherein said peripheral notches 40 are open, they being projected outside of the said outer spray directing member. As may be seen in this figure, this position corresponds with the extreme open position of the outer spray directing member.

Here again, it is noteworthy that since the peripheral notches of the inner spray directing member may assume the aforesaid open position, they are resistant to clogging and are easily `accessible for cleaning purposes.`

'For ease in assembly, the inner spray directing member is also provided with an aperture 41a of the vsame dimensions as aperture 41 but disposed opposite thereto. Upon assembly, if it be preferred, this aperture 41a may be employed in place of aperture 41 to receive pin 25.

(The lowermost portion 42 of the inner spray directing member is closed, "as may be seen in Fig. 2.

It will be noted that the aforesaid spray'directing members may assume Iintermediate positions between the extreme open and closed positions shown in -Figs. 1 and 2. Of course, the ineness of the spray emerging through the peripheral notches of the spray directing members will vary in accordance with the particular intermediate position assumed.

It will also be seen from the foregoing that the present invention accomplishes a simple, yet versatile, shower head of rugged design.

The embodiment of the invention illustrated and described hereinabove has been selected for the purpose of clearly setting forth the principles involved. It will be apparent, however, that the present invention is susceptible to being modified in respect to details of construction, combination and arrangement of parts which may be resorted to without departure from the spirit and scope of the invention as claimed.
