Abstract
A liquid spray nozzle has an adjustable head threadedly supported in the nozzle body to permit adjustment of the nozzle opening. An elongated rod extending through an eccentric opening through the nozzle head is threadedly received in one of a plurality of threaded bores located in the nozzle body circumferentially spaced about the axis of the adjustable head. When turned into one of the threaded bores, the rod holds the nozzle head in the adjusted position.

The volume of liquid discharged from a spray nozzle is usually controlled by changing the position of the nozzle head relative to the discharge opening of the nozzle. ln many cases this adjustment is accomplished by providing a threaded connection between the nozzle head and the nozzle body. As the head is threadably turned relative to the nozzle body it varies the size of the spray opening of the nozzle. ln nozzles of this type it is important to be able to lock the nozzle head in any one of a number of adjusted positions.
It is the intention and general object of this invention to provide a nozzle having an adjustable head threadably received in the nozzle body with simplified means to lock the nozzle head in any one of a number of adjusted positions.
An additional object of the subject invention is to provide a nozzle of the hereinbefore described type with a locking bolt passing through an opening in the nozzle head eccentric to the axis of the head for threaded reception in one of a plurality of threaded bores in the nozzle body.
A more specific object of the subject invention is to provide a nozzle of the hereinbefore described type wherein the nozzle bolt is adjustably accessible from the discharge end of the nozzle.
These and other objects of the subject invention will become more apparent as the following description is read in light of the attached drawing which is a crosssectional view of a nozzle constructed in accordance with the invention.
Referring to the drawing the nozzle of this invention includes a hollow body portion generally designated 6. The inlet end 7 of the nozzle flares outwardly terminating in an annular shoulder 8 for attachment to a liquid containing pipe 9. The connection between the nozzle and the pipe may be effected in any conventional manner and is herein shown as including a ring clamp 11 tightly bolted to the pipe flange 12 by a plurality of circumferentially spaced bolts 13. The flared end of the nozzle body is tightly wedged between the ring clamp and the pipe flange to hold the nozzle in place.
The other end of the nozzle body terminates in a conical surface 14 providing a discharge opening for the nozzle.
A plurality of ribs 16 rigidly connected to the interior surface of the nozzle body extend radially inwardly and tenninate in an internally threaded hub 17. The hub is coaxially located on the axis of the conical discharge opening 14. The hub 17 is provided with a plurality of circumferentially spaced threaded bores 18 concentrically located about the axis of the hub.
A nozzle head generally designated 19 is provided with a conical end 21 and-a threaded end 22. The threaded end 22 is threadably received with the hub 17 and thereby locates the conical end 21 relative to the conical opening 14 so as to provide an annular liquid spray passage 23 between the head and the nozzle body. An axially extending opening 24 is provided longitudinally through the nozzle head parallel to the axis of the head and radially spaced therefrom. This opening is selectively alignable with the internally threaded bores 18.
The size of the liquid spray passage 23 can be adjusted by threadably turning the head 19 in the hub 17. Once the proper adjustment of the spray passage is obtained an elongated rod 26 having; one threaded end 27 is extended through the opening 24 and threadably turned into an aligned bore 18. In this manner the nozzle spray head is firmly locked in the adjusted position. Furthermore, because the rod 26 extends to the discharge end of the head the nozzle head can be adjusted without dismantling any portion of the nozzle other than to remove the rod 26.
The embodiments of the invention in which an exclu sive property or privilege is claimed are defined as follows:
l. A liquid spray nozzle comprising: a hollow body internally contoured to provide a discharge opening at one end thereof; a plurality of ribs connected to said body and extending inwardly therefrom and supporting an internally threaded hub; an adjustable head having one threaded end adjustably threadably supported in said hub with the other end thereof extending into said discharge opening and being externally contoured to provide an annular opening therebetween, said head being adjustable in said hub to vary the size of said annular opening; a plurality of circ umferentially spaced threaded bores in said hub radially spaced from end concentrically located about the axis of the threaded portion of said hub; walls defining an axially extending opening through said head radially spaced from the axis thereof and selectively alignable with said threaded bores; and an elongated rod having one threaded end extending through said axially extending opening and engaged in one of said bores to prohibit relative rotation between said body and said head.
2. The nozzle set forth in claim 1 wherein the other end of said elongated rod is adjustably accessible from the discharge end of said nozzle.
