1 Claim. (01. 299-114) This invention pertains to a spray nozzle, particularly of the type to be used with spray pumps, bucket pumps, stirrup pumps or compressed air sprayers, such as are customarily equipped with hose and nozzle for discharge purposes.
The principal object of the invention is to provide a spray nozzle which lends itself to simplicity in manufacture and adaptability to plastic and die cast molding, and wherein its structure minimizes the likelihood of clogging, but in case of clogging may be conveniently cleaned. By reason of the construction as hereinaiter more specifically set forth, only two members are employed .to make up the nozzle, a body member and a cap member, as compared with the usual assembly of a substantially larger number of associated parts as heretofore employed. Thus, the invention comprises a two piece spray nozzle wherein the associated body and cap members are provided with an intermediate convolute passage by means of which the liquid is given a swirling motion followed by a swirling discharge from an eccentrically positioned spray orifice.
The full nature of the invention will be understood from the accompanying drawing and the following description and claim:
Fig. 1 is a central vertical section through the spray nozzle showing the associated members. Fig. 2 is a front plan view of the nozzle. Fig. 3 is the same as Fig. 1 showing the members separated. Fig. 4 is a rear plan view of the cap member. Fig. 5 is a side elevation showing a modified form of the body member.
In the drawing there is illustrated a spray nozzle comprising a body member l0 and a cap member ll. As illustrated, the body member is provided with internal screw threads for receiving the external screw threads of the cap member. The rear end of the body member terminates in a. reduced shank portion l2 which is internally threaded for attachment to an externally threaded conduit I 3 or valve control unit.
The body member II is formed with an an nular head ll protruding within the threaded portion and of reduced diameter to provide a sealing face l1 and an annular recess I5 for reception of a gasket ring l6. Said body member has its inner surface forwardly tapered at l8, terminating in a central discharge orifice l9 communicating with the interior thereof for providing the fluid passage therethrough.
The cap member H is formed with a flange 20 about its forward face, which flange is chamfered for receiving a wrench. Said forward face of the cap is recessed, as indicated at 2|, said recess being provided with an eccentric funnelshaped face 22 terminating in an eccentrically positioned spray orifice 23.
The rear portion of the cap member is shown in Figs. 3 and 4, and is provided with a convolute recess 24 formed within the body portion 25 surrounded by the extended flange portion 26. The inlet end of said recess 24 is positioned to communicate with the discharge orifice I 9, and its outlet end with the spray orifice 23. The convolute for'm thereof is developed by an extension therein of the body portion in the form of a curved bafile comprising a reduced neck 21 terminating in a curved head 28.
When the cap member is screwed into the body member, .they are so related that the extended flange portion 26 engages in the annular recess l5, having sealing engagement with the gasket I6. The face I1 of the body member engages the body portion 25 of the cap which surrounds the convolute recess, as well as the neck portion 21 and the head portion 28 there- '01. The assembly of the two members is such that the orifice l9 communicates with the convolute recess 24 centrally of the cap and as indicated by dotted lines in Fig. 4. Thus, the liquid forced under pressure through the nozzle is caused to travel about the outer wall of said recess past the head 28, finally reaching the restricted spray orifice 23, at which orifice the rotary or swirling motion will have been induced and transmitted therethrough.
Further, for the purpose of illustration, the body member 0 of Fig. 5 may be provided with a peripherally toothed shank H2 for direct insertion in a hose l l 3.
The invention claimed is:
A two piece spray nozzle comprising a body member provided with an axially disposed liquid discharge orifice and having a protruding portion surrounding said orifice formed with a sealing surface, a cap member adapted to screw into said body member, said cap member having an integrally formed curved baflle on the inner surface thereof adjacent the body member to provide a substantially convolute recess, said baflle being in sealing engagement with the protruding sealing surface of said body member, said recess communicating with a restricted spray orifice in said cap member positioned oil center and offset from said discharge orifice, said discharge orifice being in communication with one end of said recess and said spray orifice being in communication with the other end thereof, and an outwardly protruding peripheral flange extending about said cap concentric with said discharge orifice and eccentric with respect to said spray orifice, said orifices and integral baflle being so related as to develop a swirling motion to the discharged liquid.
