REVOLVING SHOWER HEAD Filed Aug. 20. 1949 INVENTOR.

JOHN C. SAR BU ATTORNEY Patented Dec. 23, 1952 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to a revolving shower head.

An object of this invention is to provide a shower head of the character described comprising a casing receiving water under pressure, a revolving disk at the front end of the casing, means to cause water from the casing to rotate the disk, and spring compressed plungers on said disk formed with longitudinal grooves through which water is sprayed, the arrangement being such that as pressure increases behind the disk, the plungers are pressed forwardly against the pressure of the springs which serve to return the plungers to normal position when the water of the shower head is turned off.

Another object of this invention is to provide a shower head of the character described, provided with a revolving member on which are slidably mounted spring compressed plungers formed with spray grooves through which water passes, said grooves increasing in cross section toward the rear ends of the plungers so that as the water pressure increases the plungers advance to increase the spray.

Yet another object of this invention is to provide a shower head comprising a casing having an inlet opening and a chamber communicating with the inlet opening and said casing being provided with a transverse wall, and a recess at its outer side to receive a rotary disk, said casing being formed with openings through which water passes from the chamber to the edge of the disk, said disk being formed at its edge with varied grooves against which water impinges for rotating the disk.

A still further object of this invention is to provide a strong, rugged and durable shower head of the character described which shall be relatively inexpensive to manufacture, and yet practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts. which will be exemplifled in the construction hereinafter described, and of which the scope of invention will be indicated in the following claims.

In the accompanying drawings in which is shown various illustrative embodiments of this invention,

Fig. 2 is a cross sectional view taken on line 2-2 of Fig. 1;

Cal

Referring now in detail to the drawing, l0 designates a shower head embodying the invention. The same comprises a fitting I II which may be attached to any suitable pipe to receive water under pressure. The fitting H has a socket [2 at its rear end formed with internal screw threads i3. Extending from the socket i2 is a ball head M. The fitting is formed with a. through opening it extending entirely through the fitting.

Attached to the head I i for universal movement is a casing l8. Said casing i 8 has a tubular portion is countersunk as at 2!], at its rear end. Received within the countersunk socket i9 is a packing 2| having a part-spherical inner surface 22. The tube It has a through'openin 23, The packing 2| has a central opening 26 communieating with the opening 23.

The head M fits into the part-spherical surface 22 of the packing 2i and corresponds in diameter thereto. The tubular portion 19 has an outer threaded portion 25. Screwed thereto is a coupling 25. The coupling 26 has an outer internally threaded, skirted portion 27 screwed to the threads 25. The coupling 26 also has a top or end wall or flange 29 formed with a partspherical edge 36, likewise engaging the outer spherical head M of the fitting l I.

Upon tightening the coupling threaded portion 25, the head [4 is pressed against the packing 2| to effect a universal joint connection between the casing 13 and the fitting l l.

Extending from the tubular portion I9 is an annular outwardly flaring shoulder from which extends a cylindrical Wall 35, greater in diameter than said tubular portion. The casing is also formed with a transverse wall 31 forming with the shoulders 35, a chamber 38 communicating with the opening 23. The cylindrical wall 36 extends beyond the wall 31. The front end of the casing is thus recessed or countersunk, as as 39. Extending forwardly from wall 3'! is a central stem or shaft 43. There is thus formed at the front of the casing a ring shaped recess 4| having a bottom surface 42 and an outer cylindrical surface 43. At the inner side of the forward end of said cylindrical wall 31 is an internal bead or flange 31a.

The stem 49 may be formed with an annular shoulder 45 if desired. Said stem 48 is also formed at its front end with an external screw threaded stud 45. The casing is formed with a plurality of rearwardly and outwardly inclined drilled openings 4'! interconnecting the recess ii with the chamber 38. Thus water passing through the fitting I I, under pressure, will move through opening 23, chamber 38 and openings ii. The forward ends of the drilled openings 4'! are substantially at the middle of the cylindrical interior surface 43.

on the Rotatably mounted within the recess 4! is an annular disk 59. The annular disk 5| is formed with a central opening 5|. Fixed within the through opening 5| is an outer race 52 of a ball bearing member 53. Fixed to the front end of the stem 56 is an inner race 54 of said ball bearing member. Between the races 52 and 54 are the ball bearing balls 55. Screwed to the stud 46 is a nut 56 which serves to keep the ball bearing member against coming out. The outer diameter of the disk 59 is only slightly smaller than the inner diameter of the recessed surface 43. Bead 31a extends to the outer end of the outer edge of the disk. The disk 50 has an outer surface 60. The outer surface 6' is formed with a plurality of notches BI. Each notch 6| has a substantially radial surface 62 and an inclined surface 63. Said notches terminate short of the outer end of the disk and increase in cross section toward the rear. Water passing through the openings 51 will impinge upon the radial surface 62 and serves to rotate the disk in the direction of the arrow in Fig. 4. Rotation of the disk is facilitated by reason of the fact that it is mounted on a ball bearing member 53. Some Water will pass out between the outer edge of the disk and the bead 31a. However, water pressure will also be built up in back of the disk.

The disk 58 is formed with a pair of diametrically opposed drilled through openings 62a which may be somewhat inclined to the front and rear surfaces of the disk. Slidably mounted in each opening 62a is a plunger 63a. Each plunger 63a has a rear wall 64 and a cylindrical wall 65 and a front Wall 66. The front wall 66 may be formed with a plug force fitted into the front end of the plunger. The plunger thus has an interior chamber 61. The rear wall 64 has a central through opening 58. Extending through said openings 68 is a stem 69 of a piston On the front end of the stem 69 is a piston head H. Between the piston head H and the rear wall 54 of the plunger is a coil compression spring [2. Each stem 59 is formed adjacent its rear end with an annular groove 13. the disk, adjacent each stem, is a screw l t. The head of the screw serves to clamp to the rear surface of the disk a bracket 15, formed with a notch 16 at its front end, received within the groove 13 of the stem 69.

Each plunger 63a is formed at its outer surface with a plurality of longitudinal grooves 12a, increasing in width toward the rear. It will now be understod that water passing through openings 4'! will build up pressure at the rear of the disk and force the plungers 63a outwardly, compressing the springs i2. It will be observed that water may pass through the grooves a and form a spray as the disk 59 rotates. The thickness of the spray streams will increase as the plunger moves outwardly beyond the front surface of the disk.

It will be observed that movement of the plungers will not only increase the spray but will keep the grooves 15a clean, thus the spray will be self-regulated and the spray openings Will be constantly cleaned and will not become stopped A 09.13 89' may be mounted within the outer end of the opening 5| so as to cover the nut and to prevent water from passing through the ball bearing.

It will thus be seen that there is provided a device in which the several objects of this invention Screwed to the inner surface of 4 are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understod that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
