. pf. s claims; (c1. 299-130) This invention relates to shower heads.

An object of the invention is to provide a shower head embodying means for enabling the shape of the spray or jet deliveredtherefrom to be controlled as desired and to meet varying requirements.

An important feature of the invention is directed to the novel construction and arrangements of parts employed by means of which either a ared spray of suitable size ora straight jet or column of substantially uniform diameter can be discharged from the head as may be desired and in some instances made necessary be` cause'of the particular environment in which the head is used. A shower head whose nozzle or discharge end is constructed for the exclusive discharge therefrom of a wide angle spray is ordinarily intended to be used in association with a shower stall of such dimensions as will enable the spray to be confined to a limited lateral area, to thus prevent the water from being deiiected onto adjacent surfaces, such as the floor of a bath room in which the shower stall is a part. Because of the shape of the spray delivered from a head of this character, it has never been 'and onto the floor. The spray head forming the 3 subject matter of this application is\formed so that the size and shape of the spray can be readily controlled to enable same to be used in any one of the environments just above referred' It is a further object to provide a shower head which can be conveniently and quickly adjusted manually to suit any one of the conditions herein above mentioned.

To the end herein advanced and others that will manifest themselves as the description proceeds, the invention consists in certain improvements land combinations and arrangements o f parts, as will be hereinafter fully set forth, with the features of novelty pointed out in the hereto appended claims.

In the drawing, wherein has been illustrated a preferred form of the invention,

Figure 1 is a vertical section taken through the complete head;

Figure 2 is a bottom pian view of the discharge end of the nozzle;

Figure 3 is a view in plan of one section of the head, with parts broken away and parts in section for the purpose of clearness; y

Figure 4 is a schematic section through4 the .lower section of the head 'showing the parts in a position of relative adjustment to enable a wide angle spray to discharge from the head; and

Figures is a section similar to Figure 4 shows ing the parts adjusted relatively to enable an attenuated stream to discharge from thek head. In carrying the invention into practice, use is made of a head consisting of co-operable sections A, B and C; The section A is formed at its upper 10 ,lar ange I 6. The upper portion of the section 20 B is formed with an internally threaded enlargement -I1 which adjustably accommodates a nut I8, the latter bearing against the marginal edge of la concave-convex disk I9 of'springy material. The central portion of the stock of the 25 disk is formed with an opening 20 whose-walls embrace the ball I2, as shown in Figure l, whereby to force the ballinto 4sealed engagement with the gasket 5;, the parts co-acting as will be appreciated to prevent leakage of water around 30 the ball. The section B'is also formed with a reduced nipple 2I which'opens to the ball I2 by :way of a passage 22 formed therein. Said nipple 2l is provided with a base wall 23 having an lannular series of outwardlyviiared openings 24 35 therein. At its center the wall 23 is provided with a'stem 25 of a downwardly reduced diameter, `the small end of which-is provided'with a conic f'rustrumI 26 whose large end is of. a smaller diameter than the discharge' orice 21 in the 40 head-28 ofthe section C.

The sectionC .of the device has a skirt portion 29 of cylindrical formdepending from the head 28 and fitting in said skirt is an annular member 30 formed with suitably'spaced apart V- 45 shaped utes 3l, against whose angularsurfaces angularly delivered threads of water will be de` ected as shown in Figure l'. It Will'be noted that the upper part of the frustrum 26 is formed with an annular, downwardly. land outwardly 50 ared wall 32 which, when the frustrum is in the position illustrated in Figure 1 functions to cause -a downward angular deflection 'of the water against said ilutesof the member 30, the deection `being wholly confined between the 55 upper and lower ends of said member. It will also be noted that the skirt 29 is of greater depth than the member 30, whereby to provide said skirt with a smooth annular surface 33 beneath the lower edge of said member whereby when the yparts are adjusted relatively as shown in Figure 4 the angle of deflection of the threads ofwater will be such as to not cause material impingement of the water against said flutes 3 I.

From the head 28 of the skirt 29 rises an internally threaded sleeve 34 which co-acts with the nipple 2| toenable the sections B and C of the enlargement 35. The enlargement 35 hasv an internal resilient packing ring 36a which bears against the external surfaces of the enlargement 35, there being a nut 31 on the enlargement 35 which clamps the packing against the upper edge of said enlargement as shown in Figure 1.

When the sections B and C are adjusted relatively, as shown in Figure 1, the angle of deiiection of the water pencils is such as to cause the Water to impinge against the annular walls of the parallel flutes of the member 30, the member functioning to prevent spiral churning of the water in its movement through the skirt 29. In consequence thereof, a large diameter water columnD will be formed. The diameter of this column will be the same as the internal diameter of the skirt 29. y

When the sections B and C are adjusted relatively to slightly retract the frustrum 26 into the orifice 21, the water as it leaves the oriiice will be deflected at an angle that will prevent effective impingement of the water against the member 30. By making the member of a length that is less than the depth of the skirt 29, the water will be permitted to discharge at the angle shown in Figure 4, so that the device can be used in the manner of an ordinary spray head.

When the sections B and C are adjusted relal water will be confined within controlled lateral of the sides of the tub.

The ball connection I2 between the sections B and C provides a simple means for allowing the section C to be tilted oif of the vertical center to enable the spray to be' angularly projected as desired.

In a device as herein -,shown and described, we wish to particularly stress the use in combination of means such as the frustrum 26, skirt 29, orifice 21 and member 30 for changing at will the angle of deflection of the water, to thus enable the shape of the delivered jet to be changed to meet the conditions herein set forth. To the best of our knowledge, we are the first in the art for connecting the ball with a water supply pipe;

, to provide a spray head capable of functioning in this manner, and we shall expect to' reserve to ourselves the right to make changes and alterations in the structure within the scope of the hereto appended claims without departing from 5 the spirit of the invention.

What is claimed is: 1. A shower head comprising a hollow orificed ball; a section having a chamber in which the ball is contained; a gasket in the chamber; means for 10 yieldingly advancing the ball against the gasket to maintain a position thereof so that water entering the ball can leave same through the gasket by way of the orifice of the ball; means a reduced portion on said section, the same having a depending stem formed with a conical portion; anda downwardly opening annular skirt connected with said section for movement axially relatively thereto and provided with an orice correlated to said conical portion to enable the latter to pass therethrough and project at respectively different distances into the chamber, said section having an annular series of openings for discharging water into the chamber around said conical portion.

2. A shower head comprising an annular, downwardly opening skirt having a top wall formed with a central orifice and provided with an annular series 0f V-shaped flutes extending longitudinally of the inner walls thereof; and means for delivering water to the orifice from a supply line and including a conical element mounted relatively to the skirt for movement through the orice and for projecting at respectively different distances into said skirt.

3. A shower head comprising an annular, downwardly opening skirt having a top wall formed with a central orifice and provided with an annular series of V-shaped flutes extending longi- 40 tudinally of the inner walls thereof; and means for delivering water to the orifice from a supply line and including a conical element mounted relatively to the skirt for movement through the orifice and for projection at respectively different distances into said skirt, the flutes being of less length than the depth of the skirt.

4. A spray head for shower baths including a downwardly opening jet-discharge skirt having a member therein formed with an annular series of longitudinal V-shaped flutes, the length of which member is less than the depth of the skirt, the upper end of the skirt having a wall formed with an orifice opening downwardly into 55 the skirt; and means cooperable with the orifice and adjustable axially relatively thereto for changing the shape of the jet discharging from saldskirt.

5. In a shower head, a large internal diame- 0 ter skirt having a top wall provided with a small diameter axial opening through which water can pass into the skirt from\a supply source; means including a water spreader adjustable from a position within the skirt and through the opening to a retracted position from the skirt and relative to the opening to enable a cylindrical stream of water of lesser diameter than the internal diameter of the skirt toY be dischargedhfrom the 7' skirt, the diameter of which is substantially the same as the internal diameter of said skirt.

6. In a shower head, a vlarge internal diameter skirt having a top wall provided with a small diameter axial opening through which water can pass into the skirt from a supply source; means including a water spreader adjustable from a position Within the skirt and through the opening to a retracted position from the skirt and relative/to the opening to enable a cylindrical stream of Water of lesser diameter than the internal diameter of the skirt to be discharged from the bottom of the latter; and means in the skirt cooperable with the spreader when the latter is in a position of predetermined adjustment in the skirt to cause a substantially cylindrical solid stream of water to discharge from the bottom of the skirt, the diameter of which is substantially the same as the internal diameter of said skirt, said skirt having an internal portion disposed with respect to said last named means so that when the spreader is in another position of predetermined adjustment water passing into the skirt and discharging therefrom will be converted into 10 a substantially conical spray.
