Sherman Manufacturing Company, Battle Creek, Mich a' corporation of Michig an Application July 24, 1931. Serial No. 552,934 4 Claims. (Cl. 299131) This invention is an improvement in sheet metal hose nozzles and in the method of making same, said nozzles being of the general type shown in Sherman and Hanlan Patent 1! 1,508,993, issued September 16, 1924; and the principal object of the present invention is to provide a novel nozzle, and method of making same from two pieces of sheet metal, excluding the spray point per se, as distinguished from the three part structure shown in the above mentioned patent, the part eliminated in my nozzle, and by my method being the usual stufiing box nut which holds the packing washer and completes the assembly in the old style nozzles.

A. furtherv object is to provide the sleeve with interrupted internally projecting rolled threads for engaging the threads on the base spindle to make the nozzle screw upand down and thereby open and close the valvein the nozzle. The interrupted thread is used rather than a continuous one since it creates a better outward appearance of the nozzle and comprises the equivalent of a corrugated hand hold, and furthermore it prevents the danger of drawing the shape of the sleeve or movable barrel out of alignment as might be the case if a completely rolled thread were applied at that point.

A, further object is to provide a novel method and means for preventing separation of the sleeve and spindle when assembled, by rolling an internally projecting flange in the sleeve which wi l engage the centering spider on the valve stem and prevent the movable sleeve or barrel from screwing ofi from the base portion or spindle when assembled, while permitting sufficient -movement of the parts to. operate the valve.

. Still further objects are to provide a nozzle which will be very neat in appearance; simple and economical to manufacture; and eflicient in operation; also a nozzle which will throw a uni.- form spray, or stream, and by which the water can be absolutely shut off when desired.

The accompanying drawing illustrates a nozzle embodying my invention which will be explained with reference thereto; and the claims set forth the essential features of the invention, and novel features of construction, and novel combinations of parts, for which In said drawing:

The nozzle as shown comprises a spindlel'and a base-orhose-end portion 1a, which are prefer-.

ably formed integrally of sheet brass. The base la" is internally threaded for engagement withjthe v nipple of a hosein the usual manner. .The spindle is tubular and cylindric and is adapted to telescope into the sleeve 2, hereinafter described;

and. is provided adjacentithev base'la with. a smooth outer surface portion'lb, andv beyond" this portion with a rolled threaded portion it for engagement with the interrupted. rolled 7 threads '20 of the sleeve 2'; and beyond. the threaded portion lcwithan end portionld which is, provided with ofiset openings 1e, (Fig.4). and

an axial aperture 1] for" reception of .the end of the valve stem 36, hereinafterreferred to. The base 1a and spindle 1 are preferably m'ade integrally from sheet brass'by successivedrawing operations, and the outer end of the base 1 is thickened by doubling to form anje 'gterior stiffen so Slidably mounted'upon the spindle 1 isa'i slejeve 2, whichis preferably made from, sheet brass .b'y.

drawing operations, and is longer than the smooth portion 12) of the'spindle land is adapted to tele I scope thereupon. The inner end of sleeve 2' which I is nearest thebase 1 is ofsuch internal diameter as .toslip overand loosely fit on the spindle lb, j h and at the inner extremity of the stem isa,hol-'- low flangeZa in which is seated a packinglwashe'r' 4 which is preferably enclo'sedbyinturning the end 211. of the flange after the washeris inserted.

The was her 4 slides uponthe portion ,lb of the spindle and prevents leakage of water between the spindle and sleeve. The above punch press operation of closing the end'of flangeza around the washer furthermore obviates the necessity" of threading the inner end of the sleeve and applying the usual stuffing box nut. thereto with the. washer confined in the nut, thereby eliminating the usual nut entirely and saving. the cost ofthe usual threading and assembling operations in The washer or gasket ,4 confined in the part 2a of thesleeve makes a close water-tight slidablejoint between the spindle and sleeve. I

The'sleeve2 is roll threaded adjacent the part 2a to engage the. rolled threads 1c of the "spin-- dle so that by turning thesleeve on the spindle the sleeve will be advanced or retracted longitudinally of said spindle. The threads 2c on the movinwardly upon itself as at 2fto form this part 2g,

fpassthrough the aperture while the body of the valve 3 will close the opening if sufliciently sci leaving a wall of sufficient thickness at the base ,of the thread for proper strength. This inter-v rupted thread isused rather than a continuous one; first, because it creates a better exterior appearance of the nozzle and is the substantial equivalent of a corrugated hand hold; and second,

it obviates the danger of drawing the shape of the sleeve out of alignment as might be the case if a complete rolled thread were applied at that point. g The sleeve 2 has its outer end closed by an integral head 29, the metal of the sleeve being bent and the inturnedportion forming the head. In the center of the part 2g is" formed an axial aperture 26 for the escape of watenwhich aperture is adapted to be closed by a'valve 3.1 i

The valve 3 and its stem 32) are preferably formed integrally out of brass rod as disclosed in e the aforesaid Patent No. 1,508,993. The valve has on its outer'end a tip or point 3a which is preferably conical and slightly larger in diameter at its base than the point of the valve 3,'but'is smaller in diameter than aperture 2e so the tip 3a can projected thereinto. 1

The valve stem'3b extends axially of the sleeve 2and its inner end is'so' connected to part 1d of.

the spindle that the stem will-be moved by and withthe spindle but'is capable of slight lateral vibration and'preferably free rotatorial motion thereon, as in the aforesaid Patent #1,508,993. As shown the stem has a contracted cylindrical end 3] of smaller diameter than the aperture. 1 in the end ld'of thespindle, and passes therethrou'gh, the valve stem being loosely connected to the partld by the part 3], which has a shoulder "scat one side of opening 1] and the opposite end of: the part 3 is flared or spread outwardlyas at 3d at the other side of the opening 1 The shoulder 3c enables the spindle to force the valve 3 outwardly and into the opening 2e when the sleeve 2 is turned so as to causeit to move on-the spin- I dle toward the base 1a and more or less open the aperture or close it water tight, I, i

To the stem 3b just below the valve head v3 is connected a spider or guide 5 which is slidable in the sleeve 2 and is adapted to center the tip of valve 3 in the discharge orificeQ.) When the tip of valve 3 has been e'nteredin the aperture .the wateritself will'automatically center the valve in the discharge aperture because of the yieldable or floating connection of thevalve to the spindle 1 aslin' theaforesaid patent. i I The telescopic ."movements of the spindle and sleeve are limited so. that, they cannot be separated by the longitudinal movement of the sleeve on the spindle,and so that the sleeve cannot be unscrewed and removed frcrnthe spindle bya'n annular internally projecting rib or corrugation 20: formed by apress operation at a point immediately behind the spider 5 when the sleeve is in :fully extended position. When the valve is fully opened the centering spider 5 on the valve stem 3b williengage this. corrugation and; prevent the the water is fully cut oil". 1 r H a I do not limit my invention to'the exactforms movable sleeve from screwing entirely off the base portion or spindle. r

The nozzlehas the appearance of being very heavy and the drawn sheet metal parts are so formed as to secure thickness where strength is essential, without making it necessary to use heavy, thick stainpings. I With this invention the complete spindle or hose-end member 1 may be formed integral of sheet metal; the complete sleeve 2 may be formed integral of sheet'metal; the valve-3 and stem may be formed integral out of rod metal; and the spider 'or guide 5 can be readily stamped. e a Y My method of constructing and assembling the parts eliminates various threading operations and other machine operations, both on the otherwise be necessary; and this nozzle is ex-v ceedingly economical to manufacture. .When' the point 3a is withdrawn or nearly withdrawn from the outlet in. the sleeve 2 the nozzle will throw a solid stream. As the valve is advanced toward the seat the nozzle throws a'coarse, or

medium or fine spray, and when the valve seats shown in the drawing for obviously'changes may he madewithin the scope Of'fthe claims. 7
