LIQUID-DISTRIBUTING DEVICE Filed Feb. 16, 1953 I INVENTOR 6 FINGAL C. ORR

ATTORNEYS United States Patent 2,719,7 51 LIQUID-DISTRIBUTING DEVICE Fingal C. Orr, Glendale, Calif. Application February 16., 1953, Serial No. 337,135 8 Claims. (Cl. 29969) This invention has to do with devices for distributing liquids in circular paths occupying a multiplicityof planes.

An object of my invention is to provide a novel, liquiddistributing device which is actuated by the liquid to causedrawing and the following description. Referring to the drawing:

Fig. 1 is an elevational view of a device embodying the invention;

Fig. 2 is a plan view of the device of Fig. 1;

Fig. 3 is a sectional view on line 3-3 of Fig. 1;

Fig. 4 is a fragmentary elevational view on line 44 of Fig. 2;

Fig. 5 is a fragmentary elevational view of a modified pawl mechanism; and

Fig. 6 is a fragmentary elevational view on line of Fig. 5.

More particularly describing the invention, 11. generally indicates an X-shaped fitting member having a depending central neck 12 internally threaded at 13 to receive a tube 14. The latter is slidably androtatably mounted within a main fitting 16 in the form of a tubular body terminating at its lower end in a threaded portion 17 for attachment to a supply pipe 18. Tube 14 extends through fitting 16 and is fitted with a collar 20 at its lower end to limit upward movement of the tube.

The member 11 rotatably supports a horizontal tubular shaft 22 which is closed at one end as by plug 23. The shaft is apertured at 22' within fitting 11 so that it will receive fluid delivered by tube 14. At its other end there is rigidly mounted a spray head or discharge head assembly, generally indicated by 24, and including a head 25 having a neck 26 attached rigidly to the shaft 22 and having a portion 27 at right angles thereto fitted with a discharge tube or nozzle 28. The member 25 also carries an actuator member 30 which is mounted on a pin 32 which is rotatably mounted in the fitting 25. The actuator member is attached at one end of the pin. The other end of the pin is apertured at 33 to receive coil spring 34, one end of which is anchored in an apertured abutment lug 35 on the body 25. The spring serves to bias the actuator member toward and against the lug 35.

The actuator member includes a spoon-shaped deflector end portion 38 normally in the path of liquid emerging from nozzle 28 and a laterally disposed vane 39.

The fitting 11 is provided with a laterally projecting pin 41 which is threaded into the body. Pivotally mount- 2,71 9,75 l Patented Oct. 4, 195.5.-

2 ed on this is a, pawl 42, which hangs by gravity in an inclined position. The lower end, of the pawl rests against a serrated track 44 of circular shape formed on the upper surface. of a flange, 45 mounted on the fitting 16 The pawl prevents rotation of fitting, 11 and carried parts in a counterclockwise direction as viewed in Fig. 2,

In the operation of the device liquid delivered by the supply pipe 18 passes through tube 14 to the interior of fitting 11 and then enters shaft 22 flowing to fitting 25 and. emerging at a relatively high velocity throughthe nozzle 28.. The. emerging liquid impinges upon the de-.

flector portion 38 of the actuator member, causing this member to pivot to the left, as. the device is viewed in Fig. 2. In so pivoting, the vane. 39 enters and passes, through the fluid stream serving to, carry the actuator member to a position such that it occupies substantially. 'the broken-line. position shown in Fig. 2 Spring 34 returns the actuator member to the original position- As a result of the forces involved, the head 25 and shaft.

22 rotate about the axis of shaft 22 and at the same, time the assembly carried by tube 14 is, caused to rotate about the axis of rtube. intermittently due to the reactionary force of liquidiissuing from the nozzle when the parts are. in the. position shown in Fig. 2. Any tendency. of; the discharging fluid to reverse this direction of rotation of the entire assembly carried by the member 11 is pre: n ed. by Da .4 whic p m t rot n of th afo ementioned assembly clockwise as viewed in Fig, 2 but prevents rotation in the opposite, direction.

While the pawl 42 will operate under the influencev 1 of a y a on I y pro ide a sp n to urge it t r the, flange 45. Thus iniF-igs. 5 an 6. I show a pawl 424. car ies o an elonga dvpin 4 hich accommoda e a. coil pri g o e end of hi li a inst the i e of the pawl and the other end of which 'is, mounted in slot 52 in the end, of the pin. The tension of the spring can thus be adjusted. Such a spring can be employed on the construction shown in Figs. 1--4.

Where a spring is used a foot 53 of leather or othersuitable material can be employed between the end of the pawl and the'flange member against which it works,

the foot being mounted by means of a cotter pin 54 extending through holes in the parts. Where the foot is used, the flange, here indicated by 45a, may have a smooth upper surface, friction being relied upon to prevent backward rotation. Also, with this construction, the speed of forward rotation of the tube 14, head 11 and carried parts can be adjusted by adjusting the tension of spring 51.

While I have illustrated preferred forms of my invention, I contemplate another form thereof which comprises the construction shown in Figs. 1-4 without the pawl 42 and flange 45. When the

parts

42 and 45 are omitted the member 11 and connected parts progressively rotate counterclockwise. This is due to the fact that discharge head assembly 24, as it is driven by the reactionary thrust of the issuing liquid, travels faster downwardly than it does upwardly in its rotation about its horizontal axis with the result that, in each cycle of rotation it has a longer time in which to tend to rotate member 11 and connected parts in a counterclockwise direction than in a clockwise direction, the result being the progressive advance of the moving parts counter clockwise about the axis of tube 14.

Although I have shown specific forms of my invention, I contemplate that various changes and modifications can be made without departing from the scope of the invention as indicated by the claims.
