SPECIFICATION forming pm of Letters Patent No. 700,009, daten May 13, 1902. Application tiled February 17,'1902.l Serial No. 94,491. (No model.)

T0 all whom it may concern:

Be it known that l, JOHNBEAN, a citizen of the United States, residing at Los Gatos, in: the county of Santa Clara and State ofCaliornia, have invented certain new and useful' Improvements in Nozzles; and I do hereby declare that the following is a full, clear, and eX- yact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The ,present invention has relation to that class of nozzles adapted for connectingwith .a pump, reservoir, or other source of supply containinga;liquid, whereby said liquid is projected in a solid orvunbroken stream or jet or in a` spray of the desired ineness, such nozzles being usuallyeniployed to throw insecticide or other like solution upon vegetation for the purpose of destroying the insect or fungus life thereon.

It is the purpose ot' the present invention to provide a nozzle that will be simple in construction, easily operated in throwing or projectinga solid stream or'jet or a spray of the required-iinenesslfor the'purpose intended; and it consists 'in a nozzle, constructed substantially as shownA in thedrawin gs and hereinafter described and claimed.

Figure l of the drawings is a perspective view of a nozzle constructed in accordance with my invention; Fig. 2, a sectional elevation thereof; Fig. 3, ahorizontal section taken online 3 3 of Fig. 2; Fig. 4, a similar view taken on line 4t 4. of Fig. 2.

In the accompanying drawings, A represents the shell or body of the nozzle, provided with a suitable coupling B, which coupling has an inlet a to communicate with the contracted outlet b in the plug-valve C when the two register with eachother. This coupling B may be of VVany preferred construction for attachment to a tube, pipe, orA hose or directly to the vessel4 or reservoir or other source of supply containing the liquid, although I prefer to provide said coupling with a screwthreaded socket c for connecting thereto the end of a pipe or tube.

The lower end of the plug-valve C is provided with the usual screw-threaded'nipple, with which engages the screw-nut CZ and 'washer e for tightening the plug-valve in the Vshell or body A, both of which valve and body are tapering, as is common in this class otl nozzles.

y The plug-valve C at its upper end terminates in an elliptical-formed head D, and extending from this head is the usual handle E for turning the plug-valve, said plug-valve, head, and handle being integral.

In place of having a screw Fconnected directly to the plug-valve C,whereby said screw would be carried by the valve when turned to act as a stop to limit the distance of rotation of the valve, I provide the shell or body A with an upwardl y-extendin g bracket Gl, provided with a screw-threaded hole to receive the screw F. -Thisscrew acts as a set-screw and is entirely independent of the plug-valve C, and when brought into action the end of the screw bears with frictional contact against the elliptical-formed head'D instead of using the headloflthe screw.l as a stop, thereby rendering'the'device milch-more practical and eective iulimitingthe rotation of the plugvalve. This set or regulating screw F acts to regulate the size of thesprayfby bringing the outlet b of the plug-valve C with relation to either of the side w'allsg h of the opening j in the shell or body A, said opening extending lengthwise of the shell or body and the side walls being parallel to each other.

It will be noticed that the side walls g h increase in width as they approach the center or on a line with the outlet b of the plug-valve C, or, in other Words, the edges t' are curved or segmental, bringing the greatest width of the side walls on line with the outlet in the plug-valve, so that the stream or jet from the outlet will have greater surface to impinge against, giving a much finer spray and retarding the spray at the outer edges ofthe side walls, and thereby rendering the operation of spraying more eiective. The sidewalls g h, which I shall term ,detlecting-wallg?? against which the liquid is deflected,- are provided with sharp edges t, which are on a curve, and as the spray passes over these edges it attracts and carries away all scattering drops that would otherwise drip. If the edges were iiat or beveled, a greater or less surface would be presented for the .accumulation of the IOO spraying liquid, and the result would be the liability of dripping, which the sharp edges prevent.

To obtain a broad fine spray foam, the haudle of the plug-valve is turned to bring the outlet of the valve at the proper angle to the spraying-wall, after which the regulatingscrew is turned against the elliptical-formed head to hold the valve in position. As the nozzle becomes clogged the handle is turned in the opposite direction, which action of the valve-plug will throw out the obstruction.

The plug-valve may be locked closed or the same may be brought into position to throw a solid stream by regulating the setserew with relation to the elliptical-formed head.

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

l. In a nozzle, a suitable shell or body having an upwardly-extending bracket and a regulating-screw engaging therewith and supported thereby, and a rotatable valve having at its upper extremity and above the upper end of the shell or body an elliptically-formed head against which the end of the screw is adapted to impinge, substantially as and for the purpose set forth.

2. In a nozzle, a suitable shell or body having an outlet with side walls increasing in Width in a direction near their center, said shell or body having a bracket extending out from the same, and a rotatable valve having an elliptically-formed head at its upper end and above the shell or body, and a regulating-screw supported by the bracket and adapt ed to impinge against the elliptieally-formed head, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

DAVID C. CRUMMERY, FRANK MALCOLM.
