in accomplishing this object, it has been usual In the accompanying drawing, to arrange the diaphragm in the form of two Fig. 1 is a central sectional elevation through members, each provided with perforations and one embodiment of mydevice;. 75

Referring to the drawing and particularly to difiiculty, none of which has been successful un- Figs. 1, 2, 3 and 4, l0 designates a body member til the present development. provided on its interior with a chamber 11 of 40 The present invention is designed to overcome sufficient size to hold a considerable volume of objections to prior apparatus of this type, and water or other fluid, and having arranged at one in carrying out my invention, I have provided end exterior threads 12 and by means of which a spray head consisting essentially ofa hollow the body 10 maybe attached to a source of water body in which may be retained a considerable or other fluid supply.

45 volume of water or other fluid, and forming a In some installations, it is desirable that the closure for the hollow body member is a perbody member be adjustable to the water supply, forated diaphragm provided with adjustable persuch as by a universal joint and for this purpose, forations which may be increased or decreased Ihave arranged acup-shaped depression 13 in the in cross sectional area to regulate the amount end of the body member 10 to cooperate with 60 of water or other fluid delivered therethrough complementary members on the water supply and which perforations are provided with line. straight walls for all positions of adjustment. The end of the body member 10, remote from I accomplish this desirable feature by associthe threaded portion 12. is enlarged, as indicated ating with the perforated diaphragm, above reat 14, and is preferably cylindrical and of rela- 56 ferred to, a second and innermost'diaphrogm tively considerable diameter and the outer open end of such cylindrical portion internally threaded, as indicated at 15, to receive the external threads 16 of a cylindrical member 1'7,

which has formed integral therewith and on the and the disk member 18. Formed integral with the disk 18 and on the inner face thereof is a bearing stud 21 the inner or free end of which is threaded to receive a clamping nut 22.

Rotatably mounted on the stud 21 is a cylindrical member 23 formed integral with a disk 24 which disk has one face thereof in sliding engagement with the inner face of the disk 18. The disk 24 is also provided with circular rows of perforations 25 similar-in shape .and dimension to the circular rows of perforations 19, above described as being formed in the outer disk 18.

Referring to Figs. 2 and 4, itv will be noted that the disk 18 is provided on its inner face with inwardly projecting members 26, which members are of any desired thickness and of a width substantially equal to the width of the perforations or orifices 25 in the disk 24, such members 26 being, however, suitably positioned to allow a free movement of the disk '24 on the disk 18. Also, and referring to Figs. 2 and 4, it will be noted that the disk 24 is provided on its outer face or on the face in engagement with the inner face of the outer disk 18, with members 27, which extend through the perforations or orifices 19, these members 2'7 being of any desired thickness and of a width subv stantially equal to the width of the or orifices 19.

Referring specifically to Fig. 4, it will be apparent therefore, that each set of complementary perforations 19 and 25 in the inner and outer disks 18 and 24, respectively, together with the members 26 and 27, define an effective passage having straight or parallel walls and that regardless of the distance apart'of each set of members 26 and 2'7, the parallelism of the effective walls of each passage is maintained.

Also, it will be apparent from Fig. 4, taken in connection with Fig. 1, that if a body of. water or other fluid is under. pressure, that a stream of water will pass through each set of complementary perforations or orifices 19 and 25 and that the character or shape of such stream of water issuing through such orifices or perforations will be maintained regardless of the cross perforations sectional area thereof. Therefore, it will be apparent that the aligned perforations ororlfices 19 and 25 may be regulated upon relative rotative movement of the disks 18 and 24 to deliver from the body member 10 water or other fluid by a plurality of streams of uniformly defined form, and the breaking up of the various streams of water, which is inherent in prior devices, is totally absent in the present device.

Also, it is apparent that if the disks 18 and 24 are rotated relative to each other so as to bring the members 26 and 2'7 into substantially the same plane, that the flowof water from the body member 10 may be entirely shut off.

For the purpose of rotating the disk 24 relative to the disk 18, I have provided a projection 28 formed integral with and extending upwardlyor inwardly from the inner face of the disk 24, which direction of fluid flow of each regulated passage projection is engaged in the forked member 29 secured to a shaft 30 by pin 31 and such shaft is rotatablymounted in a bearing 32 formed integral with the body member 10 or in the cylindrical portion 14 thereof.

Also, I have provided a gland in which is arranged packing material 33 held in position by a packing nut 34, engaging threads 35 formed on the bearing member 32. The shaft 30 extends It may sometimes be desirable to provide a spray such as a needle spray when water or other fluid under pressure is in the chamber 11 of the body member 10 and the cross sectional form of such needle spray may be of any desired form.

For example, in Fig. 5 there is shown a non-circular spray orifice 38 which remains always open, as for example when the member 27 on the inner disk 24 is in' engagement with perforation 19 in the disk 18, such orifice 38 being formed by channelling out perforations l9 and 25 in the respective members 26 and 27.

one end of the In Fig. 6. there is shown another modification of the needle spray, this form being of circular shape as indicated by the reference numeral 39.

.In Fig; '7 there is shown a still further form of needle spray formed by grinding the exposed end faces of the members 26 and 27, resulting in a substantially triangular perforation 40 at each end of the members 26 and 2'7.

In Fig. 8 there is shown a still further form of needle spray resulting from forming a plurality of grooves in the faces of the members 26 and.

27, this form of spray resulting in the plurality of substantially non-circular perforations 41. Any other form desired may be readily attained as will be apparent to those skilled in the art, and

as stated above, in these various forms of needle spray it is not desired that the entire flow of water or other fluid may be shut off from the body member 10 while water or other fluid is present therein under pressure. Any suitable cook or equivalent means may be provided for the water pipe line to effect complete shutting off of the fluid flow.

From the above, it appears that my invention provides for a spray head comprising a nozzle inclusive of a discharge member having a plurality of discharge passages, and means associated with such discharge member for regulating the eif'ectiveextents of opening of the respective discharge passageswhereby the facial wall area of these passages is maintained substantially uniform for varied extents of opening of these passages.

It'also appears that my invention provides for a spray head comprising a nozzle inclusive of a discharge member having a plurality of discharge passages, andmeans associated with such discharge member for regulating the effective extents of opening of the discharge passages whereby the axis of the area of opening in the is maintained substantially fixed.

Whereas I have described my invention by refm erence to specificiiorms thereof, it will be understood that many changes and modifications may said discharge member to form sets of complementary discharge passages, certain of the walls of each of said sets of discharge passages being in substantial alignment with one another, and projecting elements extending from said dis- 'charge member and said second-namedmember in opposing directions through the discharge passages of each of said sets, said elements having faces extending planarly within each said discharge passage and means for effecting relative rotation between said second-named member and of complementary said discharge member.
