Description

Feb. 28, 1967 LORD, JR 3,306,541
' ROTATING SPRAY DEVICE Filed NOV. 16, 1964 United States Patent 3,306,541 ROTATING SPRAY DEVICE Jay W. Lord, Jr., Wayne, Pa., assignor to Purex Corporation, Ltd., Lakewood, Califl, a corporation of California Filed Nov. 16, 1964, Ser. No. 411,213 Claims. (Cl. 239230) This invention has to do with rotating spray devices operable to spray liquids such as Water, cleaning solutions and the like, through a head which is rotated by a liquid driven motor contained within the body of the device.
More particularly, the invention is directed to improvements in a known type of spray device having a tubular body containing a driven shaft carrying and passing liquid to the spray head, and a rotor-governor, specifically of a centrifugal type, by which rotational influences of the rotor-governor are transmitted to the driven shaft. Thus in relation to the rotor-governor the shaft is indirectly driven by way of the rotor-governor as will later appear.
The performance of these known devices has been found objectionable by reason of the tendency of the spray head to rotate with such proportionality to the liquid velocities through the device, as to create excessive rotational head speeds at desirably high liquid throughputs notwithstanding functioning of the governor.
Accordingly my general object is to provide for a more desirable control of the spray head rotative speed in the respect of approaching greater constancy of that speed at greater liquid throughput velocities.
This objective is accomplished by provision for by-passing a portion of the liquid from rotative influences on the rotor-governor, so that the full driving capacity of the total liquid flow will be reduced to a predeterminable degree and the effective rotational speed of the spray head reduced accordingly. In this manner that speed may be kept adequate but not excessive, whatever the liquid throughput.
The invention and its manner of accomplishment will be most readily and further understood from the following detailed description of an illustrative embodiment shown by the accompanying drawing, in which:
FIG. 1 is a view showing the device in longitudinal cross section; and
FIGS. 2 and 3 are enlarged transverse sections taken respectively on lines 2-2 and 3-3 of FIG. 1.
The device is shown to comprise a tubular body internally threaded at 11 to receive a cap 12 threaded .at 13 to receive a liquid inlet conduit, not shown, the body also being internally threaded at 14 to receive a bottom cap 15. The body contains a fluid driven motor generally indicated at 16 operable as later described to rotate a tubular shaft 17 carrying a spray head 18 shown specifically, though typically, as being ball-shaped, having appropriate discharge orifices 19 and removably secured to the lower end of the shaft 17 as by spring pin 20.
The motor 16 comprises a circular member 21 having a frustoconical face 22 through which passages 23 having diametrically opposed inlets 24 extend in the substantially parallel relation appearing in FIG. 2 and angularly as shown in FIG. 1, to diametrically opposed outlets 25 in the undersurface 26 of the circular member. As shown in FIG. 1 the peripheral portion 26 of the circular member is engageable against the annular body shoulder at 27 to limit axial displaceability of the circular member inwardly of the body. Liquid delivered to chamber 28 flows through the passages 23 and imparts to the rotor-governor a rotative speed generally in proportion to the liquid velocity through the device.
The motor 16 may be regarded as having a control com ponent also in the form of a rotor-governor 29 accommodated for rotative and radial displacement about the circular member shaft 30 which extends down into bore 31 in the upper end portion 17a of the shaft 17. The rotorgovernor 29 may be made of a non-metallic material such as Teflon, and is shaped as shown in FIG. 3 to have eccentric off-balance upon rotation. Specifically, the rotor-governor is shown to have an enlarged arcuately ex tended side 29a and an opposed reduced side 29b and to be centrally slotted at 32 so that upon rotation, the rotorgovernor tends to radially throw out relative to the circular member shaft 30 in the direction of the central radius of the enlarged side 29a. The latter contains the illustrated balanced circular arrangement of passages 33 extending through the rotor-governor parallel to its axis.
The upper portion 17a of the shaft 17 carries a driving arm 34 secured to the side of the shaft by screws 35, the arm having an inner curved face 36 engageable by the rotor-governor 29 as illustrated in FIG. 3.
In operation, liquid passing through and rotatably driving the rotor-governor 29 impinges directly against the top surface of the rotor-governor 29, imparting rotation thereto and causing the rotor-governor to throw out against the driving arm surface 36, the rotor-governor speed and centrifugal force against the driving arm being generally proportional to the liquid flow through the device, and the rotative speed thus imparted by the rotorgovernor to shaft 17 similarly being generally proportional to the liquid throughput. Flowing past the rotor-governor, the liquid enters shaft 17 through openings 38 and passes through the shaft bore 39 into the spray head 18.
The structure specifically described thus far is that of a known spray device having the disadvantages mentioned of tending to impart to the spray head excessive rotating speeds at higher liquid throughputs. The present invention is concerned with so limiting the spray head rotation as to obviate excessive speeds at such higher liquid velocities through the device.
In accordance with the invention and its preferred embodiment, my objective is achieved by causing a portion ofthe inlet liquid to by-pass through the circular member 21 the rotor-governor 29 in the respect of imparting thereto no consequential rotative effect by the by-passed liquid. Such by-pass preferably is formed by a passage or bore 40 extending axially through the circular member and its shaft 30 so that a portion of the inlet water, predeterminable generally by the effective transverse passage area of the bore 40, flows directly from chamber 28 through the circular member shaft to join the rotor-governor-actuating liquid entering the shaft bore 39 through openings 38.
It has been determined in practice that the driving energy reduction due to the liquid by-pass will cause desirably slower rotation of the spray head 18, while allowing the higher liquid throughputs and spray velocities required for various cleaning operations.
I claim:
1. A rotating spray device comprising a tubular body having at one end a liquid inlet, a circular member containing liquid discharge passages, a rotatable rotor-governor rotatably driven and centrifugally displaced by liquid discharged from said circular member, a tubular shaft rotatably driven by the rotor-governor, said shaft having an opening in the wall thereof for receiving liquid from the rotor-governor, a spray head carried by said shaft, and means forming a passage through which liquid discharged from the circular member by-passes the rotor-governor and joins the liquid flowing through said shaft to the spray head.
2. A spray device according to claim 1, in which said passage extends within and through the rotor-governor.
3. A spray device according to claim 1, in which said circular member includes a head and a shaft extending through the rotor-governor, and said passage extends 3 through the circular member head and the last mentioned shaft.
4. A spray device according to claim 1, in which said shaft contains a plurality of side openings which pass liquid from the rotor-governor into the shaft.
5. A spray device according to claim 1 in which said circular member includes a shaft extending through the rotor-governor and into said tubular shaft near a side opening therein through which liquid from the rotorgovernor enters the tubular shaft, said passage extending through the circular member shaft to merge the by-pass liquid with liquid entering the tubular shaft through said side opening.
