.HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 237,684, dated February 15, 1881. Application filed June 1, 1880. (No model.)

To all whom it may concern:

Be it known that I, OHns'rnR B. Hosnonn, of the town of Williamsburg, in the county of Hampshire and State of Massachusetts, have invented new and useful Improvements in Hose-Nozzles, of which the following is a specification,reference being had to the accompanyin g drawings, which form part of the same.

My invention relates to that class of hosenozzles which are designed to throw either a solid stream or spray; and it consists in apeculiar construction of the body and plug, so that when the latter is turned in one direction 1 a solid stream of water is thrown from the nozzle, and when turned completely around a spray of water is thrown from the same nozzle or mouth-piece and, further, in the construction whereby an equal distribution of water to form the spray is obtained, and also to increasing its velocity, and which construction is fully shown in the accompanying drawings, described in the specification, and referred to in the appended claims.

In the drawings, Figure 1 is a sectional elevation, on the line a; an, of a hose-nozzle embodying my invention. Fig. 2 is a side elevation of the body of the same. Fig. 3 is a cross-section of same on the line 3 y.

A is the body of the hose-nozzle, and is supplied with several passage-ways, which will be fully described hereinafter. The end of the body next to the hose is provided with a female screw, B, into which the end of the hose is screwed. The body A is furnished with a transverse conical hole or seat, 0, into which the plug G fits and works. Opening into this hole, from the end next to the hose, are two passages, E and F. The body on the other side of the hole 0 is provided with a male screw-thread and an annular recess or depression, H, the object of which is to equalize the distribution of water to form the spray, and also to increase the velocity through the agency of the small oblique holes h, which will be hereinafterset forth. Opening into this annular recess H, and also into the hole 0, is a passage, F and there is also a passage, E, which extends from the hole Othrough to the end of 50 the body farthest from the hose. This is shown in Figs. 1 and 3. Fitting and working in the hole or seat Gis a hollow plug, G, which is provided with two holes, 9 g, from interior to exterior, one on either side. When the plug is in the position shown in Fig. l the hole 9 is exactly in front of passage F, and the hole g is in front of passage F but when the' plug is turned one-half a revolution the hole 9 is in front of passage E, and hole 9 is in front-of passage E. Opening. from the annu- 6o lar recess H are several small holes, h, drilled or cast in an oblique position with relation to the direction of the line of the hose-nozzle, as shown in Fig. 2. By having a series of small holes, through which the water is forced from the annular space H, the velocity of the water is increased, and also the flow is equally distributed, and which equalization never took plaoein hose-nozzles as previously constructed. The object of having these holes oblique is, that they cause the water to rotate and emerge from the nozzle end in the form of spray.

Screwed over the outer end of the body A is the nozzle end I. When this end I has been screwed up against the leather packing-ring 7 5 J the joint is perfectly tight, and the annular recess now becomes an annular passage, Fig.

1, for the purpose of equalizing the distribution of the water to form the spray.

The operation is as follows: To throwastream in the form of spray the plug Gr is turned as shown in Fig. 1. The water from the hose passes through passage F, hole 9, through hollow plug Gr, through hole 9 and passage F, into the annular space or passage H, from which it passes through the small oblique holes h it into nozzle end I. In passing from the annular space or passage H through holes h an equalized distribution and a rotary motion is imparted to the water, and retained by it 0 when it emerges from the mouth of the nozzle end, where centrifugal force acts upon it, and the water is thrown in alldirectionsin the form of spray. 'To throw a solid stream of water the plug is turned one-half arevolution. The water then passes through passage E, hole g, through the plug G, through hole g, passage E, into the nozzle end, and finally leaves the nozzle in a straight and solid stream without rotary motion. 10o

I am aware that nozzles have been designed for this purpose before, but none have had the peculiar construction embodied in my nozzle, consisting in the construction of an annular passage, in combination with oblique holes, for the purpose of rotating the water and causing an equalized distribution from the same, and also an increased velocity.

I do not consider that it would alter my invention if, instead of holes E, I and g, theholes E and F were made in one, and the plug G supplied with a corresponding hole of greater width, and another hole corresponding to hole 9 on the level of passage E, but not on the same vertical line with the hole g, for the annular space and equalized distribution and increase in the velocity of the water is the essential feature of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a hose-nozzle, the combination of body A, provided with passages F and E, annular passage H, and oblique holes h, for equalizing the distribution of water to form spray, and increasing the velocity, with a hollow plug, G,

provided with holes 9 g and nozzle end I, substantially as and for the purpose specified.

2. A hose-nozzle formed with an annular chamber, H, and with small oblique holes h, for equalizing the distribution of the water to form spray, and increasing its velocity of discharge in a rotary motion, substantially as and for the purpose specified.

3. In a hose-nozzle, the hollow plug G, provided with holes g g on opposite sides of the plug and on different levels, in combination with the body A, provided with acentral passage, E, and a side passage, F, the central passage leading directly into the nozzle end, and the side passage leading into an annular distributing-chamber connecting with the nozzle end by means of oblique holes, substantially as and for the purpose specified.

4. In a hose-nozzle, the body A, provided with annular distributing-recess H, oblique holes 72, and nozzle end I, substantially as described.
