M c/a a9 UNITED STATES PATENT rric \VILLIAM L. DEMING, OF SALEM, OHIO.
SPECIFICATION forming part of Letters Patent No. 511,728, dated December 26, 1893.
Application filed April 7, 1893- Serial No. 469,453- (No model.)
' My invention relates to improvementsin the art of Water distribution, and has for its object the production of a nozzle capable of ready attachment to a section of hose or tubing, and when used in connection with an ordinary force pump, adapted to throw a solid concentrated stream, or to atomize liquids for the purpose of spraying plants, bushes, or trees to rid them of vermin common to orchards and gardens generally.
The invention will be hereinafter described and particularly pointed out in the claims.
In the accompanying drawings which form part of this specification, Figure 1, represents a side elevation of my invention; Fig. 2, a longitudinal sectional view of same, with valve or plug in position for throwing asolid concentrated stream Fig. 3, a side elevation of valve or plug constituting an important feature of my invention. Figs. 4. and 5, each represents a longitudinal central section of my improved nozzle taken on line so, 0:, Fig. 1; showing also, a transverse section of valve or plug in its position for spraying and for throwing a solid steam respectively, and Fig. 6, is a transverse section of valve or plug taken on the line 3/, y, Fig. 3.
Reference being had to the drawings, in which like letters indicate like parts wherever employed, A represents the body of my improved nozzle, preferably made of cast metal, and constructed with a globe or enlargement B at one end, the latter being perforated as shown in Fig. 2, thus forming a valve seat with tapering walls a for the reception of a valve or plug which will be hereinafter described.
The advance end of globe B is flattened as at O and recessed as at D, giving to the nozzle a flaring bell mouth discharge; while immediately back of this a similar though smaller recess 17 is formed in the inner wall of globe B which latter recess communicates with the former. The opposite end of body A is provided with the usual internal screw E for connection with a hose or pump, and communication is established between such hose and the valve seat by means of a longitudinal supply channel a.
F indicates a valve or plug ordinarily seated in globe B as shown, and adjustably held to its seat by means of screw 02 illustrated in Figs. 1 and 2; said valve being further provided with a thumb key G as a convenient means of turning the same axially, and a pintle, e, projecting from one side for engaging stopf on globe B and thus limiting rotation of the valve. Near its lower end, this valve is perforated by a transverse channel g, gradually reduced in size from its inlet to its discharge end; whileat right angles thereto is a communicatingpassage hot somewhat smaller bore for purposes that will hereinafter appear. Diametrically opposite the passage h and in the face of plug or valve F is formed a recess or cup-shaped depression 1', adapted to register at times with recess b-in globe B thus forming vortex chamber 1) t'as shown by Fig. 4. Opening into the depression 7. are channelsj 70, arranged in difierent planes, and consequently entering said depression tangentially; whilethe opposite ends of each communicate with the channel 9 from which they are supplied. The channel g, thus it will be observed, performs a double function; namely, it not only serves to throw a solid stream when in the position shown by Fig. 5, but when in po sition shown by Fig. 4, serves the important function of a pressure chamber into which the water is received and held before being discharged. This being substantially the c0nstruction and arrangement of my improved nozzle, its use and operation are quite appar= ent. Vater or spraying liquid being supplied to the nozzle from a force pump, may be thoroughly disintegrated and discharged in a fine spray by manipulation of key G and its plug, until they assume the relative position in globe B shown by Fig. 4, when the liquid will be conducted from the supply toward the discharge end of the nozzle through channels 0 and h, and by the latter introduced into thetapering channel g. The ends of said channel g in this position, being closed by walls a of the valve seat, prevent passage of the liquid in these directions leaving but one means of escape; namely, by way of tangential channels 3', 7r, into which the liquid is forced from opposite ends of the channel g. Owing to the reduced or smaller diameter of tangential channels j, k, it will be observed that'the liquid is given an accelerated force when projected from them into depression 2', and entering saidv depression in different planes the two streams are given a violent whirling motion in chamber i-b from whence the liquid is discharged through the flaring mouth D of the nozzle in the finest spray or mist If it is now desired to throw a solid concentrated stream from the same nozzle, it isonly necessary-to rotate plug or valve .F until the smallerwendof channel 9 registerswith recess 1), and its larger or opposite end with supply channel cas shown by-Figsp2tand 5'. Again, it beingvdesired to'throwacoarse spray for sprinkling purposes, or fotcleansi-ng the'several passages of the nozzle from sediment or foreign matter, it is only necessary to rotate Y plug- Fin" the same direction'a :few degrees furthelgwhen the channel 71 vwill register with theadischargeopening D and the partsas- 'sume aposition the reverse of that illustrated by-Figs; and when'it is desired to stop the discharge of liquid from thenozzle positively, inorder to avoid the waste :of liquid, while for-instance transferring the spraying apparatus from one part of an orchard or garden to anothenth'ekey G and plugF controlled thereby, are given a still further turn until the pining transverse discharge passages in diiferent planes converging toward their outer ends, a main supply channel, and a taperingor reduced pressure channel intersecting theplug and com municating'with said" passages and channels, su'bstantially'asdescribed.
