3 Claims. (Cl. 299-421) My inventionrelates to a guard for the spray deflecting extension of a nozze of the type shown in my application, Serial No. 581,582, filed March 8, 1945, now PatentNo. 2,530,671 issued on October 3, 1950, wherein the nozzle has an extension projecting beyond the discharge orifice of the nozzle and provided with a surfacealong which the streamis discharged from thenozzle orifice, and by which-the stream is deflected laterally and spread into a flat stream of progressively increasing width; it i Inasmuch as any imperfections in the surface of the deflector, and especially at the edges thereof where the stream takes off therefrom, impairs the accuracy of the spray pattern it is important to protect said surface and edges from injury, and it is the principal object of my invention to provide a simple, convenient and inexpensive guard which affords such protection.
I from at one side ofthe discharge orifice l3 "and this extension 15 has a deflector face [6 along which the stream is discharged from the orifice [3, this deflector face being curved lengthwise as inaccuracies or defects and as such face and edges may become damaged inlhandling or..in use; a guard is provided, in accordance with the present invention, to safeguard the deflector face and. edges of such nozzles or similar nozzles against Otherobjects of theinvention are to construct accidental injury. the guard so that it is readily attachable to and This guard, in its preferred form, comprises an removable from the nozze; to hold the guard open coil helical spring IQ of suchlcircumferential securely in position so that it will not become size toaccommodate the nozzle extension l5freely displaced or otherwise interfere with the deflected therein and provided with facilities at the oppostream; and to provide a guard which does not site ends for detachable engagement respectively materially add to the wei ht of the nozzle nor with the nozzle body and the outer end of the obstruct observation of the operation of the extension l5 so as to hold the spring outstretched nozzle, all these and other objects being accomand in a fixed position wherein it does not interplished as pointed out more particularly herew fere with the operation of the nozzle. inafter and as shown in the accompanying draw- Preferably for attaching the inner end of the ing, in which: guard spring I 9 to the nozzle body I I, said spring Fig. 1 is a side view of a deflector nozzle looking is formed at its inner end with several close adat the deflector face side thereof and showing a joining coils 20 of reduced diameter and the guard mounted thereon in accordance with my inner end portion of the nozzle body II is: of a invention; reduced transverse size to accommodate said coils Fig. 2 is an outer end view of the nozzle and 20 thereon and to provide stop shoulders 2| guard of Fig. 1; against which said coils 20 abut.
Fig. 3 is an inner end view of the nozzle and With the body ll of the square cross section guard of Fig. l with a portion at the inner end form disclosed herein, suflicient reduction in size of the guard broken away; and 40 of the body I I to accommodate the small diam- Fig. 4 is a lon itudinal sectional view of the eter coils 20 may be provided by merely removnozzle and guard taken on the line 22 of Fig. 1. ing or omitting corner portions of the body as In the drawing, the reference numeral iii inindicated at 22 to form adequate shoulders 2i dicates the nozzle as a whole, which comprises M and at the same time leave sufiicient of the flat a body H of square cross section with an opening sides of the square beyond the coils 20 for appli- I2 therethrough which is reduced at one end of cation of a wrench thereto for attaching the the nozzle body, hereinafter referred to as the nozzle to a pipe or other conduit on which the outer end, to a relatively small orifice is which nozzle is to be mounted. constitutes the discharge orifice of the nozzle. At the other end of the guard spring IS the At the inner end of the nozzle body the open- 59 latter terminates in a relatively flat end coil 23 ing I2 is internally threaded as at M, for conwith the end portion of the wire bent radially nection thereto of a pipe, hose or the like through inward as shown at 24 to the center of the coil wlrich liquid is supplied to the nozzle. At its where the extreme end portion of the wire is bent outer end the nozz e body I i has a relatively long axially toward the other end of the guard spring integral extension [5 projecting forwardly there- 55 as shown at 25, and the outer end of the deflector extension is formed with a socket 26 to receive the wire end 25 and a groove 21 leading radially from the outer end of the socket 26 in which a portion of the radial wire 24 seats to hold the guard spring against turning movement around the nozzle and deflector extension.
This radial groove 21 extends in a direction toward the side of the: extension [5 opposite the deflector'face l6 side thereof so that the radial wire 24 will not obstruct the path of the spray l1 discharged from the end of the deflector face and the outer nd coils of the spring guard [9 are, of course, of sufiicient diameter to afford ample clearance for free and unobstructed passage of the spray therethrough;
For applying the guard spring H) on the nozzle, it is merely necessary to introduce the body end of the nozzle between the two last widely spaced convolutions of the spring at the outer end of the latter and thereupon move the nozzle body I1 and extension l5: lengthwise within the spring until the reduced inner end: of the nozzle body is engaged within the coils: of reduced diameter at the inner endof the spring l9 and then stretch the springoutwardly and engage the wire end in the socket 26 with the radial Wire 24 seated in the groove 21, said spring 19 being of such normal length that it is stretched under sufflcient tension, when thus applied, to beheld thereby securely against displacement.
For removal of the guard spring, .it-is merely necessary to releasethe outer end of the spring from; the socket 26 and. groove 21 and then withdraw the extension 15v and nozzle body l-l endwise between the two last widely spaced convolutions at theouter-end of thespring:
Thus. the guard is simple. and: inexpensive, readilyattachable and removable, is of light weight,v permits observation of the nozzle operation at all times, effectively guards the deflector face and edges and? does not interfere with the nozzle operation.
While'I have shown anddescribed my invention in a preferred form, I am aware that various changes and modification may be made therein without departing from the principles of my invention, the scope of which is to be determined by the appended claims.
I claim as my invention:
1. The combination of a nozzle having a defiector projectingtherefrom, in the path of discharge from the nozzle, saidnozzle anddeflector each having a seat, and a deflector guard comprising an axially distended helical spring surrounding the deflector and having the opposite ends thereof engaged respectively in said seats.
2. The: combination of a nozzle having a deflector projecting therefrom in the path of discharge from the nozzle, of a deflector guard comprisinga-helicalspring surrounding the deflector and annularly engaged at one end with the nozzle, said spring being axially distended and having an axially disposed extension at the other end engaged withthe outerend ofthe deflector.
3. The combination of a nozzle having a deflector projecting therefrom in the path of discharge from the nozzle, said nozzle having an annular seat and said deflector having a recess in the outer end, and a deflector guard comprising an axially distended helical sprin surrounding the deflector and having a coil at one end engaged in said annular seat and having a central portion at, the other end engaged in said recess.
