3 Claims. (Cl. 299-150) This invention relates to a iiow regulating device.

Water ilowing from a spout such as in a sink creates a splashing and many types of aerating devices have been utilized to eliminate splashing. It is the principal object of this invention to provide a device which when attached to a faucet will eliminate splashing.

It is an object of this invention to provide means for discharging a stream of water which will not splash and which means can be varied in accordance with the line pressure.

It is a further object of this invention to provide means for reducing the velocity of a stream of water and insuring that each particle of water is discharged at the same rate of flow.

Other objects and advantages will be readily apparent from the following description.

In the drawings:

Figure 1 is a perspective view of a device embodying this invention attached to a sink spout.

Figure 2 is a section taken along line 2 2 of Figure 1.

Figure 3 is a view similar to Figure 2 with the diverter in a lowered position.

Figure 4 is a section taken along line 4 4 of Figure 3. I

Figure 5 is a perspective view of the diverter.

Figure 6 is a top plan view of the velocity impeding means before insertion into the device.

Figure 7 is a side elevation of the velocity impeding means of Figure 6.

In the embodiment illustrated, a spout 10 has a threaded extremity 12 onto which the imperforate cap 14 is screwed. The cap is hollow forming a chamber and has the lower extremity thereof converging. A diverter 16 is mounted on the upper extremity of a post 18 which has six equally spaced arms 20 forming a spider. The outer edge of arms 20 is formed to complement the tapered extremity of cap 14 and thus seat the diverter 16 Within the cap. It is readily apparent that by loosening (Figure 3) or tightening (Figure 4) cap 14 the distance between diverter 16 and the outlet 22 of spout 10 can be varied. It is desirable that the upper surface of diverter 16 be serrated as at 24 to prevent shutting olf ow when the cap is tightened.

As water ows out spout 10 it strikes diverter 16 and is directed onto water dividing means. This means may be a screen, a rough surface or in this embodiment a plurality of pins. The pins 26 are arranged in two rows offset from each other and mounted on a strip 28. The pins and strip are preferably of a water-resistant material such as nylon or the like. The strip 28 is curved and tted into the extremity of spout 10 surrounding outlet 22.

2,832,643 Patented Apr. 29, 1958 ice In operation, Water is delivered to spout 10 from the usual source. The water stream is turbulent and parts thereof llow at different rates caused partially by friction with the inner surface ofthe spout and by changing direction of the iiow. Also the line pressure varies substantially aiecting the velocity of flow. All these factors contribute to cause splashing of Water as it strikes a surface after being discharged from the spout. When the cap 14 is screwed onto the extremity of the spout, the ow from outlet 22 is directed by diverter 16 onto the water dividing means or pins 26. Here the stream of water is broken and the Water discharged below with all particles at a uniform velocity. The water then passes between the arms 20 of the spider forming six streams which converge below the extremity of cap 14 because of the converging extremity thereof. Thus a smooth, even, non-turbulent stream is discharged. The velocity of this stream is controlled by tightening or loosening cap 14 that is varying the distance between diverter 16 and outlet 22 thus compensating for variations in line pressure. When desired, the device may be flushed by lowering the diverter 16 to the position seen in Figure 3 wherein the water ows through the device in a substantially unaffected state.

While what hereinbefore has been described is the preferred embodiment of this invention, it is readily apparent that alterations and modifications can be resorted to without departing from the scope of this invention and such alterations and modications are intended to be within the scope of the appended claims.

We claim:

1. A flow regulating device for a spout outlet comprising: an imperforate cap longitudinally adjustable on said spout, water dividing means surrounding said spout outlet and diverter means adjustable with said cap and diverting flow through said outlet onto said dividing means whereby adjustment of said cap determines the velocity of water discharged therefrom.

2. A ow regulating device for a spout outlet comprising: an imperforate cap longitudinally adjustable on said spout, water dividing means surrounding said spout outlet and diverter means adjustable with said cap and diverting ow through said outlet onto said dividing means, and means in said cap reuniting water from said dividing means and discharging same as a stream having a uniform velocity and wherein adjustment of said cap determines the velocity of Water discharged therefrom.

3. A flow regulating device for a spout outlet comprising: an imperforate cap longitudinally adjustable on said spout and forming a chamber beneath said outlet, water dividing means in said chamber, water diverter means mounted in said cap and in ixed relationship therewith diverting flow of water through said spout.

outlet onto said water dividing means, whereby adjustment of said cap controls the velocity of water discharged from said spout.
