HOSE-NOZZLE! SPEOIFIGATIONTormingpart'of Letters Patent No. 6C 9,845, dated March 12, 1901. Application filed August 23, 1900. Serial No. 27,795. (No model.)

To (all, w/tom z t viz/any concern: Be it known that I, JoHN H. MELAVIN, Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Hose- Nozzles, of which the following is a specifica tion.

This invention relates to nozzles for regulating the flow of water from a hose, and is particularly adapted for use in Washing carriages or woodwork, where rapid changes in the velocity and shape of the jet are required. The invention consists in the improvements which I will now proceed to describe- I 5 and. claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a longitudinal section of a nozzle embodying my invention. Fig. 2 represents a perspeczo tive view showing the method of the nozzle by one hand. The same reference charactersindicate the same parts in both the figures.

Referring to the drawings, the nozzle com- I prises a rigid metallic section a, having at one end an internally-threaded portion Z, into which is screwed the threaded coupling of a hose 6, and at its other end a threaded portion m, to which is attached the flexible delivery-section 70, which has body portion of rubber or other elastic material and an internally -threaded metallic bushing is, detaciiably engaging the externally-threaded portion 1%. The rigid section a is divided 5 into two parts by a partition 12, through which the water may flow by way of an opening c, which is surrounded by a valve-seat and is normally closed by a valve d, that is held against its seat by the pressure of the water in the hose and by a spiral sp'ringf. The thrust of the springf is sustained by a plug j, which is screwed into the section a and may he removed to allow-the removal of the spring f and valve d. To" allow the flow of water through the nozzle,the valve 01 is forced away from its seat-by pressure of the hand of theoperator against the button or'push-knob h, which acts on the valve through a stem 9-, which passes into the section a through a go stufiingbox'p and is attachedi'at its opposite endsto the knob and the valve.

operating The outer surfaces of the knob h and the section a are preferably covered with rubber to guard against scarring of the articles operated on through carelessness of the operator. I

In using this device the nozzle is held in such a way that the knob may be pressed inward by the ball of the thumb, while the flexible tip of the nozzleis held betweenthe thumb and forefinger of the same hand, as shown by Fig. 2. By pinching the-end of/the portion In the outlet may be contracted, thusinereasing the velocity of the jet and altering its shape and character. At the same time the pressure on the knob maybe varied to alter the pressure of water flowing to and through the flexible delivering-section, this change being efiected by a'portion of the same hand the fingers of which are employed for vary- 7o ing the size or shape of the outlet. Therefore the user may employ one hand for another. purpose, such' as turning a wheel of the carriage being washed, and with the other hand not only cause the water to flow full '75 force or stop or vary between these points, but also change the character. or shape of the jet,whether the latter is slight or on full.

force. When the nozzle isreleased, the valve automatically closes and stops the flow of wa- [.er. Ordinarily for washing carriages and the like a flexible hose without a nozzle is used, the variations in shape and velocity of the jet being caused, as in this case, by pinching the end of the hose; but when, as often happens, the end ofthe hose is dropped the water continues to flow uselessly and consid erable waste results, whichis prevented by the use of a device such as the one described. On, the other hand, however, none of the nozgo zle's now in use having means forshutting off the water are suitable for the purpose indicat-ed, as the water issues from them in their difierent adjustments with either too much or too little force and the jet is too compact or too finely divided as spray. In addition the changes in the character of the jet cannot'be made with sufiicient ease or rapidity.

I claim- 1. A nozzle having two liquid-controlling loo means, one for varying the pressure of water.

on its way to the outlet of the nozzle'iand the other for varying the shape or character of the jet, the said two controlling means being through one side of the rigid section and provided at its outer end with a push-knob, and a flexible section detachably secured to the rigid section and having a compressible 'de;

livering end, the relative positions of the push-knob and the compressible deliveringend being such that the push-knobmay be pressed inwardly by the ball of the thumb and the delivering end compressed by the thumb and forefinger 0f the'hand holding the nozzle, substantially as described Intestimony whereof I have affixed my signature in presence of two Witnesses.
