1 Claim.

This invention relates to devices commonly applied to, and used with, watering hoses.

One of the objects of this invention is to provide a sprinkler withquick-changing means between a Wider spray and a central single stream Fig. 2 is a longitudinal midsectional view of the nozzle, open for the central discharge.

Fig. 3 is a cross section on line 3-3 of Fig. 1. Fig. 4 is a cross section on line 4-4 of Fig. 2. Fig. 5 is a longitudinal midsectional View of a slightly modified form of nozzle. Fig. 6 is a fragmentary plan View of the housing.

Fig. is a side viewof the housing .portion of ,-H; Fig. 6 as seen in the direction of the arrow 'I'.

Fig. 8 is a fragmentary rear view of the removable clamping ring.`

Fig. 9 is a cross section on line 9*-9 of Fig. 8. As illustrated, the rear end of the sprinkler nozzle is formed to screw and t on a hose, thisv portion being indicated at I0.

This portion It is provided with a cup-shaped extension II, which is provided with distinct openings i2 and I3, one for feeding the wider t; spray, and another for feeding the central single stream discharge.

The sprinkler head is adjustably and turnably mounted on the cup-shaped extension I I and consisting of an outer housing I, an inner sleeve I5, z5 and an intermediate partition I6, all being firmly united so as to turn together on the cup-shaped extension II.

In other words, when the outer housing I is :75 this case being the opening I'I in the inner sleeve I5, to form the communication between the inside of the cup-shaped extension II and the space formed by the inner sleeve I5y and the partition I B, whereby any water may reach the, central single stream discharge; and, for another thing, to feed by way of the opening I2 and through another of these additional openings, in this case being the opening I8, jointly in the inner sleeve l5 and the partition I6, to form the communicav tion between the inside of the cup-shaped exm tension I I and the space formed by the partition and the outer housing I4, whereby any water may reach the wider spray cap I9 when the united structure is turned so that the opening I8 comes into alignment with the opening I2, as is thecaso i y, in the modified form of Fig. 5. I

From comparing Figs. 2 and 5 it is evidenty that a turning of the united structure upon the cup-shaped extension in one direction gives a clear connnunication for the central single spray; while, a turning in the opposite direction gives a clear communication for the Wider outer sp-ray.

While the head is turned for the central single y discharge, this may still be adjusted for a larger or less amount by means of the adjusting sleeve i 25" 2B, of which the innermost end 2l may be made to l seat tightly upon the washer 22, so that, by a very ne opening, a ne spray may evenv be had through the central discharge, though, by a full opening of this sleeve 2), a larger rather solid 30 stream may be had, which may be useful in hosing oi, a sidewalk or similar surface. The Whole united structure of outer housing Id, innerA sleeve I5, partition I6, cap I9, and adjusting sleeve 20, are rmly, though turnably, 35

held to the cup-shaped extension I by means of the screw-pin 23. i v

. The cap I9 may be crimped directly to andv over the edge ofthe housing I4 though a separate clamping ring 24 has been indicated. 40

This clamping ringl may even be shaped so as to'facilitate an exchanging of caps with different,

` larger or smaller apertured, spraying means.

Each of the projections, or outwardly extending edge portions 26, are preferably shaped tovform 55 wedge-like means when seen from the side, as illustrated in Fig. 7.

The clamping ring, suitable for such an edge, takes eventually the form illustrated in Figs. 8 and 9; While the outer edge may preferably be in form of a smooth fiange 21 the opposite edge would naturally have to have notches to correspond with the notches in the edge of the housing M and also Wedgelike as indicated at 28 in Fig. 9.

To assure a quick and positive proper location of the turning position of the housing on the cup-shaped extension, stops are provided on the rear base portion I0 as Well as on the housing, or united structure, as indicated in Fig. 3, one stop 29 being o-n one part, while the other stop 30 is on the other part, whereby the housing may be quickly and positively brought to aligning position for discharging through either the wider spray or the central single stream discharge; though, of course, the previously referred to communications may be opened more or less without turning to the full-discharge stop positions.

The cup-shaped extension is not necessarily of the cylindrical form illustrated in Fig. 2, as will be understood from the illustration in Fig. 5, in which this extension Ila is conical, and the sleeve portion shaped.

From the above, and from the illustrations, it should be understood that any discharge from a connected hose can be shut off entirely by reason of the fact that the openings l1 and I8 can be. far enough apart that neither will be in aligning position.

Having thus described my invention, I claim:

In a hose sprinklerhead of the type described, a base having a portion to screw to the end of a hose and having a cup-shaped extension with distinct discharge openings, a head having a portion to turnably fit on said extension with an outer housing and a partition between the housing and the portion forming distinct compartments, a wide-spray cap over the outer compartv ment, a central narrow-spray means in operative relation to the inner compartment, adjusting means for the narrow-spray means whereby the narrow spray may be adjusted between a singlestream full discharge and a fine spray, and the head having distinct communicating openings for the compartments to individually align with the openings in the extension.

|55, of course, correspondingly PAUL ECKARD.
