2 Claims.A (Cl. 299-126) The present invention relates particularly: to that form of sprinkler heads commonly used in the distribution of water over lawns but that may be readily adapted to other applications.
We have found that sprinklers of commerce are seriously faulty in two respects; first, they are not subject to proper lubrication, principallisI because the lubricating oil applied is easily washed away, and, second, they are so constructed and arranged that but a single form of spray is delivered.
It is, therefore, one object of the present invention to provide a spray head of the character indicated so constructed and arranged that when a lubricating oil is placed therein it will remain for an almost indefinite period of time.
yAnother object of the invention is to provide a sprinkler head that can be quickly and easily adjusted to form a spray of any desired character.
Still another object is to provide a spray head that consists of few and simple parts, economical to manufacture, quickly and easily assembled, strong, durable and highly efcient in its practical application. f
In the drawing:
Figure 1 is a'longitudinal section through a device embodying our invention, partly in elevation.
Figure 2 is a sectional view on line 2-2 of 30 Figure 1. i
Figure 3 is a sectional view on line 3--3 of Figure 1.
Referring now more particularly to the drawing, we show at I a base member by means of 35 which a suitable connection may be made to a hose or other water supply. This member includes a circular plate 2 disposed at right angles to the water inlet and concentric thereto and proand its length being substantially double that of the height of the flange.
Formed integrally withr the portion 9 and extending outwardly from its middle portion to lie in a plane at right angles to its axis is a flange IIJ. Depending from the flange I0 in parallel relation to portion 9 is a flange Il having an internal diameter of a size to permit its rotation about flange 3 in close relation thereto. In the chamber 'I is mounted a ball bearing I2, and when in position as shown the rotor member 8 seats upon the outer race of the bearing through the medium of an internal rib I3.
The several parts described are so tted that the rotor 8 will rotate freely and without frictional contact with the parts 2 and 3, yet will effectually prevent water from reaching the chamber 'l over the flange 3.
To prevent water from entering the chamber 'l at the top we provide a cover I4 which slidably engages the tubular nozzle 4 as at I5 and seats upon flange I0 to rotate as a unit therewith. The ball bearing I2 is secured in position by a nut I6 on the nozzle 4, and the cover I4 is held in position by a nut Il on nozzle 4, but the thread on the nozzle is directed opposite to the direction of rotation of the rotor so the nut and rotor will not bind.
Mounted on flange I0 as at I8 is a bracket I9 extending upwardly and terminating in a tubular head 20 disposed in axial alignment with nozzle 4.
At 2l is a spray tube removably mounted in head 20 by means of a bayonet lock 22 and terminating in a dispersion plate 23.
It is clear that when water under pressure is Adischarged from the nozzle 4 it will at first travel along the axis of the tube 2| as indicated at 24, but v,when it reaches the curved portion 25 of the tube it is deflected laterally as at 26. But when vided with a peripherad flange 3 directed for- 40 travelling in this new direction the water strikes wardly in the direction of water flow.
The member I also includes a tubular portion as 4 axially disposed with relation to plate 2 and having open communication with the water passage 5 its forward end 6 forming an open discharge for the water. The tubular portion 4 and the flange 3 form an annular chamber 1, and thevtubular member is externally threaded from the chamber outwardly to its end.
A rotor member is indicated generally by the reference character 8, and this member includes a tubular body portion 9 having an external diameter slightly less than the internal diameter the dispersion plate 23, which is disposed to intercept it as shown in Figure 4, and this contact causes the stream to break up into a more or less ne spray that spreads radially about the device from the area immediately surrounding it to a n more distant point. Moreover, the contact of the 0 sprayed water over a circular area of a size depending upon the water pressure and the conformation and position of the dispersion plate.
An important feature of the device is that the operator may provide himself with a large of the flange 3 so it will rotate easily therein, 55 number of spray `tubes of various forms, and by mounting the proper tube in the bracket he can secure an almost unlimited number of spray effects.
Although but one specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction and mode of application and assembly, may be made without departing from the scope of the invention as indicated in the accompanying claims.
We claim:
1. A device of the character described comprising, a base member including a liquid discharge nozzle and an annular chamber encompassing the nozzle, ball-bearings seated in the chamber in concentric relation tothe nozzle, a
tubular member seated on the ball-bearings in the chamber and having an outwardlydirectedY ange of the tubular member provided with a tubular portion disposed in spaced and axial alignment with the discharge end of the nozzle, and a spray forming element removably mounted on the said tubular portion in direct communication with said nozzle.
2. A device of the character indicated comprising, a base member including a liquid discharge nozzle and an annular chamber encompassing the nozzle, anti-friction bearings seated in the chamber in concentric relation to the nozzle, a tubular member seated on the bearings and having an outwardly directed flange extending over the top wall of the chamber, said flange having a depending ange 'formed thereon to closely'encompassthe outer surface of the cham- Vber wall, a cover mounted on the tubular member to excludeliquid therefrom, and a spray forming element fixedly mounted on the outwardly directed flange of the tubular member and disposed in spaced and axial alignment with: the discharge endV of the nozzle.4
