IMPROVEMENT l Specilication forming part of Letters Patent No. 198,515, dated December 25, 1877; Re October 28, 1879; application Jled October 6, 1879.

To all whom it 'may concern:

Be it known that I, JOHN H. JOIINsON,of

the city ot Chicago, (look county, State of Illinois, have invented a new and useful Improv'ement in Hose-Nozzles, ot' which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is an elevation, the main portion being shown in section; Fig. 2, an enlarged section with the plug removed, Fig. 3, a section at .z m of Fig. 2, looking to the left. Figs. 4 and 5 show the plugin different positions; Fig.' 6, a section at y of Fig. 4; tFig. 7, a section at z of Fig. 2. Figs. 2, 3, and 7 are enlarged.

This improvement relates to that class of,

hose-nozzles which are so constructed that a solid stream can be thrown, and also so that by changing the position of the plug or cock ythe water will escape from the nozzle in the form of a spray instead of a. solid stream. l

In the drawings, A represents the nozzle; B, the barrel, which receives the plug or cock; cl. b, recesses in the barrel upon opposite sides thereof. c d are continuations ot' the recesses a b, and are, as shown, at right angles tofu b. These passages c d do not open directly into the passage through the nozzle, but open into the plug', which is provided with openings, so arranged that the water can pass through the plug into the main channel in the nozzle when the p lug is in proper position.

The wall of the barrel extends across the passa-ges c d, as shown at e, Fig. 2. rlhe wall at the end of the passage c Iis made straight, or nearly straight, as shown atf, Fig. 7. I

O is a three-way cock or plug, having a passage, g, through it, and also a passage, 7i., opcn ing into the passage g.

i, Fig. 1, shows the outlet from the passage or chamber c to the main passage through the nozzle. There is a similar outlet from the passage d. Y

When the plug is in the position shown in Fig. 1, the passage d is in line with the passage -through the nozzle, and the water will N HOSE-NOZAZLES.

issue No. 8,951, dated usual; but if the plug or cock be turned so as to bring the opening h opposite to the inlet, the direct flow ot' the water through the nozzle will be cut off, and it will pass rst through the opening k into the passage g through the plug or cock; and when the plug is in this po sition the water wilLpass into the two recesses a b and through the passages c d, and, comin g will be detlected and passage, passing through in contact with the wall f, thrown into the main and emerging therefrom in the form it spirally, of a spray.'

The water can be entirely shut ot't by turning the plug, so that the portion opposite the opening h will close the opening into the bar rel.

I am aware that hose-nozzles have been 1n ade having two passages from the barrel to the main channel, but not opening directly from the barrel into the main channel. When so constructed these passages are liable to become filled up by obstructions passing through the water, which cannot be easily removed. With my construction this cannot happen, for the moment the plug is removed the passages are all 4exposed to view.

The peculiar forms of the passagesa b e d give to the water a spiral movement, unaided by the form of the main channel or passages leadingi from the barrel into such main channel.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. In a hose-nozzle, the barrel B, provided with recesses a Z1 and passages c d, in combination with the three-way plug O, all constructedand operating substantially as and for the purposes specified.

2. A plug-nozzle provided with ducing passages located directl and within the plug-chamber, passages are exposed when the plug is re-A moved, substantially as speeitiec y JOHN H. JOHNSON. Witnesses:
