1 Claim. (Cl. 299131) This invention relates to improvements in spray nozzles of the type generally employed with garden hose.
An object of the invention is to improve the structure of spray nozzles to produce an efficient nozzle that is durable and efiicient, and which may be economically manufactured.
Another object of the invention is to provide a device of the kind mentioned, which may be conveniently and accurately adjusted to throw a spray of varying spread and character, and which will substantially avoid a drip at the spray orifice, whereby the nozzle may be used without projecting a part of the stream vertically at the nozzle outlet, but which will project the stream away from the user of the nozzle.
Additional advantages inherent in the structure will appear from the following detailed description taken in connection with the accompanying drawing, in which:
Fig. 1 is an elevation of the nozzle;
Fig. 2 is a longitudinal sectional view through the device taken substantially on the line 2--2 of Fig. 1;
Fig. 3 is a cross-sectional view taken substantially on the line 3-3 of Fig. 2; and
Fig. 4 is a cross-sectional view taken substantially on the line 44 of Fig.- 2.
In the embodiment of the invention illustrated in the drawing, the'device is shown as including a base section A having a cylindrical body portion I, the exterier of which is provided with spaced, annular knurled ribs 2 whereby it may be conveniently manually engaged and operated. The interior of the body portion I is formed with an internal annular recess 3, in which a washer 4 is seated. The interior of the body I is provided with a threaded section 5 forming a threaded socket adapted to be screwed upon the usual threaded hose terminal. The inner wall 6 of the member A has a central opening I therein, the walls of which are beveled outwardly.
A member B, constituting an internal conduit, is in the form of a hollow stem 8, having an internal bore 9 open at its inner end, but which terminates inwardly of its outer end. An outwardly flaring flange I0 is formed around the inner opening into the bore 9, which fits within the opening I in the wall 6 of the base member, and is connected into said opening to form a tight joint. The outer end of the member B is formed with a reduced cylindrical section I I forming a recess. A head I2 is formed at the outer end of the stem 8. This head has a beveled face to the center of which a flanged stem I3 is integrally connected. -Inwardly of the head I2, and at the outer extremity of the bore 9, are lateral orifices I4, which serve to direct the stream entering the inner end of the bore 9 laterally into the recess formed around the reduced portion I I of the stem 8. The member B has a part of its exterior wall ,threadedIforming a threaded section I5.
The member Bis also provided with an annular groove Y I6 positioned inwardly from the threaded portion I5, which groove is adapted to constitute the seat for a split ring II. The walls of the ring I! bevel outwardly. The ring constitutes a stop for the external barrel of the device. It also permits easy assembling of the stem with the exterior barrel, as will be hereinafter more fully described.
The external barrel member C comprises a generally. cylindrical member I8 which is provided barrel.
witha pair ,of spaced annular knurled ribs I9,
one of which is at the inner end of .the member 0 and the other of which is spaced outwardly therefrom, these knurled portionsproviding convenient means for engaging and rotating the when the member C1 is threaded over the member B, it willmovelongitudinally in respect thereof ,in both dire ctions upon being rotated, as willbe readily understood. The inner end of the member C is formed to provide an enlarged recess 2| in which is seated a packing ring 22, the outer face of which seats against a cupped metallic washer 23. The end of the recess 2| is threaded as at 24, and is adapted to receive in threaded engagement a complementary threaded screw plug 25, having a spaced spanner wrench recess 26 therein.
The outlet end of the member C is formed by an annular wall 21, the inner face of which is beveled toward the outlet orifice. The angle of the inner face of the wall 2! is formed at an angle complementary to the belev of the outer face of the head I2. The outer face of the wall 21 is planar.
of the spray is in the formation of'a cone having 50 packing ring radially inwardly against the stem 8, thereby forming a liquid-tight joint.
The member C is then slipped over the outer end of the member B and the threaded sections I5 and 20 interthreaded. The member C is then rotated to move it inwardly in respect to the member B and, as the washer 23 passes over the split ring H, the ring I! is compressed sufficiently by the contact of the beveled surface thereof with the internal surface of the washer to permit continued movement of the member C inwardly of the member B. The ring I1 then expands,and the high inner side thereof forms a stop, limiting the outer movement thereafter of the member C, in respect to the member B, to maintain the parts in operative and assembled relation.
The parts are so dimensioned that whenthe member C is in its innermost adjustment, as illustrated in Fig. 2, the outlet orifice of the nozzle is closed by the beveled wall of the head I2 contacting the inner beveled face of the wall ,21.
As the member C is moved outwardly in respect to the member B by rotating the same, the
Y liquid stream passing through the bore 9 enters the space between the reduced section II of the v member B and the inner wall of the member C through the transverse orifices I4. As the beveled face of the head I2 is moved away from the inner beveled face of the wall 21, the passageway to the nozzle orifice is valved to produce a stream annular in form, which is directed tangentially inwardly against the flanged stem I3.
I The stream is then deflected outwardly in a truncated cone-spray formation, the volume and spread of which may be varied by rotation of the member C.
The formation of the inwardly opposite bev- ,f eled wall 21, in relationship to the beveled outer face of the head I2 together with the location of -the flange stem I3, is effective to prevent downward drip from the spray orifice and to I cause the body of the stream to be deflected outwardly away from the spray nozzle, the extent of spread and the fineness of the spray being accurately determined by the relative adjust- ,ment of the member C in respect to the member B. When the head of the stem I3 is beyond the plane of the outer face of the wall 21, the spread Qawide base and the spray is finely dispersed.
As the space between the face of the head I2 of the claim may be made without departure ,VP- tent 15;.
from the invention.
. What I claim and desire to secure by Letters In aspray nozzle, the combination with a hollow stem having a valve plug at one end and a recess in the periphery thereof, of a revoluble barrel enclosing said stem having interfitting threaded engagement therewith, whereby upon rotation of said barrel relative longitudinal movement in respect of said sleeve is imparted ing an outlet orifice and providing a valve seat for said valveplug, a packing member carried 3 by said barrel vat the opposite end to said outlet -orifice, said packing including a metal Washer on .its forward face, and a compressible split ring thereto, awallat onewend of said barrel formmounted in-saidrecess in said stein having a frusto-conical surface, the greatest diameter of which faces said washer topermit movement of said barrel in one direction for the assembly of the stem andbarrel, and limiting movement in the opposite directionaftersaid members are .assembled, the. greatest diameter of said split M ring being disposed opposite to said metal washer when said stem and. barrel are in assembled file of this patent: r
