Patented Aug. 4, 1953 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a spray nozzle and more particularly to such a nozzle adapted to be mounted on a paint spraying machine of the type used by city traic departments for striping parking lines and center lines, etc., on streets and roads, and has for its main object to provide a nozzle of this character having relatively few and sturdy parts to facilitate continuous and uninterrupted performance and economical replacement of parts as well as the ready and easy cleansing thereof after use.

Other objects and advantages will hereinafter appear, and a clear definition of the structure and unitary assembly of parts comprised in my improved paint spray nozzle will be disclosed in the following description taken together with the accompanying drawings in which:

Figure l is a side elevational view,

Figure 2 is a top plan View, showing particularly the strainer member,

Figure 3 is a bottom plan View, showing the slot and aperture from which the paint is sprayed,

Figure 4 is a longitudinal sectional View taken centrally through Figure 1,

Figure 5 is a sectional view taken on the line 5 5 of Figure 6,

Figure 6 is a top plan view of the part shown in Figure 5, i

Figure '7 is a bottom plan view of the part shown in Figure 5, and, f

Figure 8 is a perspective view of the spacer member shown in Figure 4.

It is here mentioned that while the nozzle of the present invention emits a spray of substantially thin wall, spreading out towards opposite sides and laterally of the spray machine on which the nozzle is mounted, yet the spray machine in general use is equipped with a pair of spaced apart masking shoes in the form of iat metal sheet members, the lower edge of which rides along the pavement longitudinally of the machine and the line being painted, to govern the width of said line and prevent the paint spray from exceeding the desired width. My improved spray nozzle is adapted to produce a line of desired width in conformity with the distance apart at which said masking shoes may be set by the operator.

Referringnow to the drawings in detail, the numeral Ill designates the case of the nozzle which is threaded centrally in its upper end to receive the correspondingly threaded hanged strainerretaining nipple I I. The nipple II is internally threaded for suitable 'communicable engagement with a supply pipe of the paint reservior of the aforementioned paint spraying machine, the lower end of said nipple having the smooth bore I I' extending a relatively short distance upwardly therein to serve as a retaining means to hold the periphery of the strainer member I2 against the spacer member I3 which in turn engages the flanged portion I 4 of the jet member I4, the neck portion I5 of which snuggly though removably engages the bored opening I'I in the case I0. As thus explained and as shown particularly in Figure 4 of the drawings, the unitary assembly of the component parts in my improved nozzle is rendered obvious, and further description will disclose the zo-operative relationship and action thereof in use.

Of course, the necessary compression to drive the paint through the nozzle is provided by and within the paint spraying machine on which this improved nozzle may be mounted, and is no part of the invention.

The strainer member I2 positioned as shown in the Figure 4, clearly is adapted to withhold foreign particles from the jet member I4 to assure a continuous and smooth flow of paint therefrom, and as the smooth bore I I in the nipple I I impinges the outer periphery of the strainer member I2, thus holding it securely against the upper face of the spacer member I3 it is evident that no paint reaches the jet member I4 except, through said strainer member I2. And, the bearing of the lower edge of the nipple I I angularly against the upper face of the spacer member I3 brings the lower face of said spacer member to bearagain'st the upper rface of the flange I 4' of the jet member I4 so that the lower face of said flange is held in leak-tight engagement with the flat circular face I0' interiorly of the case I0.

The central opening I3 through the spacer member I3 vadmits the paint to the slot I6 in the upper face of the flange I4 and thence through the spreader slot I8 Vdisposed transverselyof and in communication with said slot |16.

Now, in actual use of the improved paint spray nozzle, the concave formation of the bottom of the slot I=6 in the jet member I4 tends toinduce the flow of the paint toward the center aperture I8 produced at and by the intersection of the slots I5 and I8 with the result that as the paint (under pressure from the pumping mechanism in the spraying machine) is forced from the slot I8 the relatively narrow width of said slot I8 causes the paint to fan out while still within the confines of the slot, following the walls of the slot to the extent of the opposite end limits thereof and emitting a spray of paint of relatively thin dimension, which spreads out fan-wise laterally of the paint spraying machine to effect a painted strip from 3" to 8" wide, depending on the distance that the nozzle is mounted from the street surface.

It is here noted too, that the device of the present invention is capable of variation well within the meaning of the foregoing description, the accompanying drawings and the appended claims, as for example, the normal width of the slots I6 and I8 is substantially gli", although when this dimension is decreased the result-ant paint spray is ner and of lighter deposit. If, on the other hand, this dimension is increased, say, to 1%4, the resultant paint spray is thicker and of heavier deposit. It is here pointed out, however, that the present invention is adapted to efficiently handle paint of such standard consistency as usually comes from the paint manufacturer, with little or no thinning.

It is further noted that in the event that extra heavy paint deposit is required, a shallower jet member is provided, but with no change in the gf slot dimension, in which case the spray producing influence of the walls of the slot I8 is lessened due to there being a shallower and proportionately less wall space in the slot.

Also, when the end-to-end dimension of the slots I6 and i8 is shortened the resultant spray is of greater force and narrower width with respect to the paint line so produced on the pavement.

Various sizes of the improved nozzle are provided to accommodate a wide variety of work, and the smaller sizes are even used for crop spraying and kindred purposes.

While I have shown and described the preferred embodiment of my invention, it is obvious that further modiiication is possible within the spirit and scope of the appended claims, and the invention is not therefore limited to the specic structure shown in the accompanying drawings.

What is claimed is:

l. In a spray nozzle of the type herein described comprising in combination a nipple, a portion of which is screw-threaded into -a case or body portion, means on one end of said nipple for suitable communicable engagement with paint supply means in a paint spraying machine, a strainer member within said case or body portion means on the other end of said nipple compressing said strainer member to hold the strainer member against a spacer member, a spacer member having an opening therethrough for communication with a jet member, a jet member flanged at one end and having a neck formed at the other end, a substantially narrow slot in the flanged end of the jet member and a substantially narrow slot in the other end of the jet member, the said slots being disposed transversely of and in communication with each other, and an opening centrally through said case or body portion to receive the neck form of the jet member.

2. In a spray nozzle of the type herein described comprising in combination a nipple, disposed-Within a case or body portion, means on one end of said nipple for suitable communicable engagement with paint supply means in a paint spraying machine, a strainer member within said case or body portion counterbore on the other end of said nipple compressing the periphery of said strainer member to hold said strainer member against a spacer member, said strainer member being of relatively slightly greater diameter than said counterbore, a spacer member having an opening centrally therethrough communication with a flanged jet member having a neck formation at one end, a substantially narrow slot having a concave bottom surface in the anged end of the jet member and a, correspondingly narrow slot in the other end of the jet member, said slots being disposed transversely of and in communication with each other where the iianged end and the neck portion of the jet member connect and an opening centrally through said case or body portion to removably engage said neck formation of the `jet member.

3. In a spray nozzle of the type herein described comprising in combination a case or body portion adapted to threadably receive a nipple member, =a nipple member having thread means on one end for communicable engagement with paint supply means in a paint spraying machine and having counterbore means on the other end for impinging the periphery of a strainer member against a spacer member, a strainer member of substantially semi-spherical shape adapted to t into said counterbore means in said nipple in peripheral engagement therewith, a relatively iiat spacer member adapted to engage the peripheral edge of the strainer member on one side `and the flanged face of a jet member on the other side, an opening centrally through said spacer member for communication with the jet member, a anged jet member having a round neck formed thereon, a substantially narrow and concave bottomed slot in the hanged face of the jet member and a correspondingly narrow at bottomed slot in the face of the round neck of said jet member, the said slots being disposed transversely of and in communication with each other at the point of their intersection, and an opening centrally through said case or body portion and adapted for releasable engagement with said round neck on the jet member.
