4 Claims.

This invention relates to a sprayer nozzle for afhose ofthe type used for watering lawns and itisOnel object ofthe invention to provide a nozzle having attached thereto a spike or prong adapted to be' forced intothe ground and support the nozzle' Yin position for discharging Water onto a lawn,'tlie spike orprongrcarrying a plate mounted in such' position that water discharged from the nozzle" willA strike the plate and be formed into aspra'y;

An other `object of the invention is topprovide a nozzle of this `characterwherein the sprayforming plate is provided with a shankextending rearwardly from .the plateandf pivoted to the spike so that theplate maybe tilted to angularly adjusted positions and thus controlthe form of the spray `forniedloy the discharged water.

Another object'of the invention is toV provide a spray nozzle wherein the shank of the sprayforming plate`is pivoted to thesupporting spike by a pin'carrying an arm which extends diag cnallybetween the nozzle and the rear portion of the shank andhas movementtoward and away from the rear edge of the spikeas the pin is slid ingitudinaiiyihrog'h the spikeand the shank,

the arm thus sliding along the upper edge of the shank and creating Vafcal'n Yaction vwhich causes the spray plate to' be tiltedl vertically and prevented from-V beingiorced,downwardly `by action of aV streaniofwater dischargedfromrv the nozzle and striking theupper'face of the plate. Y e

Another `object of the" invention is to provide a'sp'ray nozzlefhaving a spraying plate pivoted to a supporting spike for thenozzleand moved to an angularly adjusted position byan arm carried by'a pivot lpin for the plate, the said arm carrying afinger which prevents entire displacement of the pin and thus prevents'the plate fromV becoming detached fromY the spike.

Another object ofthe invention is to provide a spray plate so formed that a spray will cover a relatively large area of lawn.

Fig. 3 is a rear view of the nozzle.

Fig. 4 is a view taken along the line4-4 of Figure land showing the nozzle in bottom plan and its spike in transverse section. v

Fig. 5 is a sectional view taken longitudinally of the nozzle along the line 5- 5 of Figure 2.

Fig. 6l is a side view showing the spray plate tilted to an adjusted position.

This improved spray nozzle has a nozzle l formed of castmetal and internally threadedras shown in Figure 5, so that it may be screwedupon the threaded terminal coupling 2 of a hose 3. The usualrubber gasket or washer 4 forms a waterti'ght joint between the nozzle and the coupling 2`V and `forwardly of this washer the nozzle is Ytapered and formed with an outlet opening 5 through which a stream of water is discharged from the nozzle. A spike 5 extends downwardly from'the forward portion of the nozzle and is of such length that when it is forced into the ground the nozzle will be supported close to the ground in substantially a lhorizontal position, as shown in Figure l. By having the spike rectangular in cross section its at side faces will prevent turning of the shank in the ground and the nozzley will beheld in position to discharge Water in a predetermined direction.

In order to form a spray of vWater discharged from thenozzle there has been provided a plate.

'l disposed infront of the nozzle and carrying a s h ank 8 vvhich projects rearwardly from the spray plate. A slot extends longitudinally of the lshankrfromthe rear endgthereof and forms forks 9 for straddling the spike 6, the forks and the prngwbeingformed with aligned openings through whichI a pin I!! of stiif metal is passed tiserve as a pivot. pin and mount the plate Anotherobject of the invention isy to provide" a spray nozzle which is simplein construction and capable' of being applied to a `terminal couplingfora hose of conventional form.

The invention is illustrated in the accompany'- ingdrawings"'vvherein:f l Fig. 1 is a side view showing the improved spray nozzle-in use.

. thlQgh-tlflem to pivotally mount the spray plate.

fr.A tilting movement vertically to adjusted posi- `between thatshown in Figure v1 and the. raisediposition shownin Figure 6. The'forks 9` areof suchnlengththat when the pinis passed the forks will project rearwardly from the spike and underthe rear portion of the socket` l. The strand 4of-Vwire from which the pivot pin I 0 is formed-is .bent toform an arm l I extending "from" the pin in a horizontal plane ata rearward incline under the nozzle transversely thereof,

and upon referring to Figures 1 and 6 it will be seen that when the pin is shifted longitudinally through the forks and the spike by pressure applied to one end of the pin the arm will gradually move towards the spike through space between the forks and the nozzle. The upper edge faces of the forks extend rearwardly at a downward incline and thus provide cam surfaces which bear against the under surface of the arm and cause the shank to be tilted about the pivot pin and swing the spray plate vertically to adjusted positions during longitudinal movement of the pin and the arm. Therefore the spray plate will be tilted vertically from the position shown in Figure 1 toward that shown in Figure 6 and since the stream of water discharged from the nozzle strikes the sloping upper surface of the plate a spray will be formed having characteristics which may be modified by tilting of the plate to adjusted positions. The free end portion of the arm Il is bent to form a finger I2 which terminates close to the free end of the pivot pin and since this pin overlaps the outer side face of one of the forks Q longitudinal movement of the pin through the forms and the spike when shifted toward the positions shown in Figure 2 will be limited and the pin can not become displaced from the openings through which it passes. The fact that the arm ts between the forks and the under surface of the nozzle causes a gripping action upon the arm when the forks are tilted upwardly by pressure of water striking the upper surface of the plate and the plate will be rmly held in a set position as the pin and its arm will be prevented from accidentally shifting transversely of the forks and the nozzle.

When this improved spray nozzle is in use the nozzle is screwed upon the terminal coupling 2 of the hose and after the hose has been extended l across a lawn a sufficient distance the spike is forced into the ground and as water discharged from the nozzle strikes the spray plate a spray will be formed which moves forwardly from the plate. If it is found that a spray of the desired form is not formed lby the plate it is merely necessary to apply pressure to an end of the pin and force the pin longitudinally through the shank and the spike. This causes the diagonally extending arm to move transversely of the forks and as it is shifted longitudinally across the forks it will also move diagonally thereof and impart tilting movement to the shank to raise or lower the plate according to the direction in which the pivot pin and the arm are moved. The finger l2 not only serves to limit longitudinal movement of the pin but also serves as a member against which a thumb or finger may be placed when shifting the pin towards the position shown in Figure 4.

Having thus described the invention, what is claimed is:

1. A sprayer nozzle comprising a nozzle open at its rear and adapted for application to a hose, said nozzle having its front end formed with an outlet opening, a member secured to the forward portion of said nozzle, a sprayer plate in front of the nozzle having a rearwardly extending shank slotted from its rear end to form forks straddling the said member, said shank being formed with openings registering with an opening formed through the said member, a pivot pin passing through the registering opening and pivotally mounting the shank for vertical swinging movement of the plate to angularly adjusted positions, said forks having their rear portions projecting rearwardly from the said member under the rear portion of the nozzle, and an arm extending diagonally from one end of said pin at a rearward incline in a horizontal plane back of the said member and transversely of the said member between rear portions of the nozzle and the forks and having wedging movement between upper edges of the forks and the nozzle to tilt the shank and move the plate vertically to angularly adjusted positions relative to the outlet opening as the pin is slid longitudinally through the forks and the said member, said arm having its free end portion provided with a forwardly extending nger for engaging the outer side face of a fork and preventing displacement of the pin from the registering openings of the forks and the said member.
