Specification of Letters Patent. Patented June 7, 1910.

Application filed August 7, 1909. Serial No- 511,726.-

vention is to design a novel and sim lestructure of sprinkler especially adapted or use in connection with gas washing tanks.

Other objects, andthe advantages of .my invention, will appear in the course of the following description in which reference is made to the accompanying drawings, forming a part of this specification, and in which, Figure 1 is a vertical sectional view through a portion ofa gas washing scouring tank, illustrating my improved sprinkler in elevation therein. Fig. 2 1s a plan view of my improved sprinkler removed. Fig. 3 is an enlarged vertical sectional view through the nozzle and nozzle head, with the sprinkling .arms removed. Fig. 4. is a transverse sectional view on the line H of Fig. 3. Fig. 5 is a transverse sectional view through one of the s rinkler arms, and illustrating the spray re ector and its manner of connection, and Fig. 6 is a longitudinal section through the parts shown in Fig. 5.

In the practical'embodiment of my invention as herein shown, I provide an inlet pipe 1 arranged vertically, and externally threaded adjacent its upper end, upon which upper end is disposed the lower externally threaded end of the nozzle pipe 2, which is'closed at its upper end by a threaded ca 3, and provided adjacent said upper en with a series of' openings l, which lead Within the bore of a nozzle head 5, having a series of radially threaded o enings 6, through; its wall, and is rovidbd with a contracted lower portion fitting snugly about pipe 2 below its perforations 4. Within the bore of head 5, between its openings 6 and the lower end thereof, is arranged packing material 8,'and a packing ring 9 oldin said material, which prevents the escape of 'quid between the pipe 2 and the contacted portions 7 of sad head, the lower end of said head being flared and grooved at 10 whereby to collect the fallin spray uponthe exterior surface of the hea and permit the same to drip from its lower end away from the nozzle pipe 2. A plurality of radial-outstanding' sprinkling arms 11 have their inner ends threaded to be screwed within the openings 6 of the head 5, said arms. being provided intheir length with a/plurality of discharge openings, arranged in longitudinally extending spiral series, and threaded for a purpose to be hereinafter described. As shown, the arms 11 are inclined outwardly and downwardly from the head 5, and are closed at their outer ends by end caps 12, beyond their outermost water discharge openings, thus forming pockets at their ends for sediment and other impurities in the water which in the ordinary con-v struction of sprinklers tend to clog up said discharge openings.

As shown in Figs. 5 and 6, the water discharge openings of. the arms 11 being, as before stated threaded, are adapted for the reception of threaded nipples-13 each of which has anoutstanding bracket arm 14 and a deflector'plate 15, the inner edge of which is inclosed within the material of the nipple 13 at one side of its opening 16, said deflector plate 15 being of suitable flexible material whereby it may be angularly adjusted within the jet of liquid flowing outwardly through nipple opening 16 by means of a set screw 17 tapped through the outer end of bracket arm 14. In this manner, the water discharge openings of the arms or essarily of minute proportions (thus endangering clogging) whereby to'permit a fine inner end rotatably engaged within a depression within the end cap 3 of. said nozzle pipe 2, the said rod 19"and said head 5 being ordinarily locked together for rotation by means of-a nut 20. The rod may be provided upon its outer end with a hand'wheel 21, and-when the sprinkler is used in connection with a gas washing or scouring tank, said rod extends upwardly through the .upper end or hood 22 of' the scouring tank 23 more particularly the nipples 13 are not necandthesaid hand wheel 21 thus forms a means for indicating whether or not the sprinkler is in operation As shown particularly in Bi 3, collars 24: and 25 are screwed upon the ad acentthreaded ends of the inlet pipe 1 and nozzle pipe 2 respectively, said collars abutting one another and being provided with transverse registered openings through which suitable fastening means may be secured in the present instance the inner angular ends 26 of i in the same plane, and the openings of the othel 'alternate arms in planes between the planes of the openings of the first mentioned arms.- 1

Having thus described my invention, I claim 1. A rotary sprinkler embodying a plurality of outwardly and downwardly inclined sprinkler arms, each having a plurality of dischargeopenings and a removable end cap upon its outer end forming a sedimentpocket beyond the outermost opening.

2. In a rotary sprinkler, a sprinkler arm having a discharge opening, an] apertured nipple, secured within said opening, a flexible baflie plate having one edge anchored within the material of said nipple adjacent its apertures, and an adjusting screw tapped 'through'a portion of said nipple plate to ad-t just. the same.

' 3. In a device-of the character described,

. ceases vthe combination with a casing, of a nozzle pipe centered within theupper portion of said casing, a nozzle head surrounding the endof said nozzle pipe,'sprinkler arms extending from said head, a rod threaded through said head to rotate therewithand bearin uponthe -nozzle pipe end, sai rod extend ng upwardly through said casing, and provided with a hand wheel exteriorly thereof, substantially as described.

4. In av device of the character described, the combination with a casing of a water pipe, a nozzle pipe. disposed thereon, said pipes being provided with abutting collars having registering transverse openings, a nozzle head disposed upon said nozzle plpe, sprinkler arms extending'fromsaid head,

and rods extending radially from said pipe and having angular inner ends locked through the transverse openings of said collars, and having their outer endssecured to the casing, whereby to center the said pipes within the said casing, substantially as described. w

5. A sprinkler of thp character described, comprising a rotary nozzle head, a sprinkler arm arranged upon said nozzle head and provided with an aperture, a flexible baflie plate arranged upon said sprinkler arm 'adjacent said aperture whereby the water passing through said aperture may strike against said bafile plate and be sprayed, a sorew arranged upon said sprinkler arm in engagement with said" flexible baflle plate and adapted to angularly adjust said baffle plate,

substantially as described. 1 In testimony whereof I atfix my signature in presence of two witnesses. 1
