EDVARD A. BENEDIOT AND CHRISTIE BENEDIOT, OF SALEM, OHIO, ASSIGNORS TO THE DEMING COMPANY, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 564,500, dated July 21, 1896.
Application filed A prill7, 1895. Serial No. 546,017. (No model.)
To all whom t may concern:
Be it known that we, EDWARD A. BENE- nic'r and CHRISTIE BENEnIcT, citizens of the United States,residin g at Salem,in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Spraying-Nozzles; and we do hereby declare -the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to apparatus for spraying plants, bushes, vines, or trees for the purpose of treating them with various insecticides or disinfectants, the use of which in practice has been found so essential to their proper cultivation, protection, and development, as well as that of the fruit which.
This being the nature of our invention, the improvements herein set forth consist particularly in a nozzle for use in connection with a suitable force-pump and intervening hose or tubing, by means of which liquid compounds maybe forced from a reservoir or receptacle and conveniently applied to said trees, vines, and fruit with the greatest degree of economy. The characteristic features of this nozzle are a cylindrical valve-body, a rotatable valve-plug therein, means for limiting and graduating the extent of such rotation, means for throwing a solid stream, a single or a double converging fan-like spray, and means for readily disgorging or cleansing the nozzle when occasion requires, all as will now be more fully described, and particularly pointed out in the claims following.
In the accompanying drawings, which form part of this specification, and in which like letters indicate the same parts wherever employed, Figure 1 represents a side elevation of our improved nozzle with cock-handle in position for throwing a solid stream. Fig. 2 represents the same when valve is entirely closed. Fig. 3 is a central vertical section through Fig. l; Fig. 4, a similar section with valve in position for disgorging. Fig.- 5 is a horizontal central section cutting the valve body and plug, the latter being in position for delivering a double converging fan-like spray.
C is the main inlet to valve-body'A, located by preference diametrically opposite the discharge, and c is a projecting lug cast or otherwise formed upon the edge of body A, for use in limiting rotation of the valve.
D represents a rotatable valve-plu g provided at one end with an angular handle E, carrying a set-screw d, adapted to coact with lug c, for graduating and limiting rotation of the valve, while at its opposite end said plug is provided with a suitable washer and nut c f, respectively, for retaining the plug in position and taking up wear thereof. V alve-plug D is perforated transversely by a channel F, which is rapidly reduced toward its disch arge end and terminates in the comparatively small discharge-opening g, while in the same plane with the latter said plug is perforated by a second auxiliary opening h, of similar size,intersecting channel F at an angle thereto and at the juncture of said main channel F with the discharge-opening g.
This being substantially the construction of our invention, its use and operation are as follows: Vhen it is desired to throw a solid stream, handle E is placed in the position shown by Fig, l, whereupon the liquid in use will be forced directly through channel F, discharge-opening g of the plug D, and out between beveled sides `ay h of the orifice B. It being desired to throw a single fine fan-like spray, handle E is turned until the projecting end of set-screw d engages lug c on the body A, in which position discharge-opening g of plug D will be partly closed by the inner beveled lip a of the oriiice B, and the liquid then breaking upon this lip is thoroughly disintegrated and spread. Thus it will be seen that set-screw d, engaging by its point the lug c, affords a positive stop for plug D in its rotation, enabling said plug to be re- ICO turned with accuracy and precision to a given position after being rotated upon its axis, as for the purpose of disgorging, and the adjustability of said screw d With relation to the lu g c serves to present a greater or smaller portion of a stream from discharge-opening g to inclined lip a of oriiice B, thereby producing a coarser or finer single fan-shaped spray, as may be desired. If, however, it should be desired to throvsr a spray of greatest body and coarsest quality, it is only necessary to rotate plug D, by means of handle E, until discharge-opening g registers with the beveled lip l), in like manner as it had in the former instance registered With the opposite lip, at which time auxiliary opening h in the plug will be partly closed by the lip a of orice B, the openin g and 7i occupying corresponding positions with relation to the lips b a, respectively, whereupon a stream of the liquid in use Will be projected upon each of the beveled lips a and I) and by them deflected so as to converge, producing a coarse fan-like spray. Presuming now, as is so1ne times the case when the heavier solutions are used, that the valve has become clogged by sediment or foreign matter, the several openings in plug D may be quickly and eectively cleansed by rotating the plug until its handle E points beyond the nozzle in the reverse direction from that indicated in Fig. l; and when in this position it will be seen that the solution first enters the discharge-opening g and then passes out through the' dischargechannel F, carrying With it all sediment. A still further revolution of plug D than that last described, to a point Where the head of set-screw d abuts against one side of lug c, serves to entirely close all openings by Vinterposing an unbroken portion ofplug D beneath the orifice B, whereupon all discharge from the nozzle is effectively stopped.
Having thus described our invention, what We claim is 1. In a spraying-nozzle the combination with a conical body having a discharge-orilice with oppositely-beveled denecting sides, of a valve-plug having diverging dischargepassages therein adapted to register with both of said sides, substantially as described.
2. In a spraying-nozzle the combination with an inclosing body having a dischargeorifice with defiecting sides, a rotatable valveplug having diverging discharge passages adapted to register with both of said sides, a cock-handle for rotating the plug, a lug upon the body for limiting rotation of the plug, and a set-screw interposed between said handle and lug, substantially as described.
In testimony Wherof We subscribe our signatures in presence of two Witnesses.
