The body 1 has l an upstanding tubularV85 neck 22. y s. ,j l The numeral 23 marks a hollowhead hav-- ingra bottom 24. The bottomi24`of the head 22 rests on theftop of the bodyl and,isle-9612V cated about the vineclr22, as Figure 1 will show. A ring 25 isheldby securingelements 26 on the bottom 24 of the head 23, and holds a packing 27 iniplace about thev neck 22, to,^ avoid leakage. y I

The top of the `head 28`carries av cup, shapedliousing 28 within which is locateda ball bearing'29.v The lower end of-a shaft- 30`is threaded atv44iinto the bottom of thebody 1. The upper end of the shaft n30 is ice' threaded into the upper end of the ball bearing 29, and the upper end of the shaft 30 may be held to the upper end of the ball bearing by means of a pin 31. The shaft 30 constitutes a retainer which holds the hollow head 23 on the body 1 for rotation. The ball bearing 29 is protected by a cover 32 which is threaded on the outer end of the housing 28. In the top of the cover 32, a Stub shaft 33 is mounted for rotation, the shaft 33 being provided at its inner end with a disc like foot 34 which is rotatably mounted in a recess 35 formed in the under surface of the cover 32. The cover 32 exercises a double function, in that it protects the ball bearin 29, and also holds the stub shaft in place or rotation.

The numeral 36 marks a curved brace rod which is pivotally connected at 37 at its inner end withthe outer end of the stub shaft 33. The head 23 has a lateral projection 43 provided. with a recess 39 (Figure 1) in which slides a brake 38, adapted to cooperate with the top of the body 1. The brake 38 has a reduced stem 40 supplied with a turning head 41V external to the member 23. A compression spring 42 is interposed between the turning head 41 and the end of the projection 43. The stem 40 is threaded into the projection 43.

The hollow head 23 has a tubular transverse portion 45 (Figure 4). The numeral 49 marks an outlet pipe having diverging arms 48 provided with inwardly extended ends 47 held by couplings 46 on the part 45 of the casing 43, the construction being such that the outlet pipe 49 can swing with the axis of the part 45 as a center of swinging movement. A valve casing 50 is threaded on the outlet pipe 49, and a nozzle 51 is threaded or mounted otherwise on the valve casing'50. In the valve casing 50, a valve 52 is rotatably mounted, and controls the How through the nozzle 51. The valve 52 has a large gear 53 meshing with a smaller pinion 54' on a shaft 55 journaled in the valve casing 56, the shaft55being provided with a handle of any desired kind, whereby rotation can be imparted conveniently to the shaft.

The outlet pipe 49 has outstanding ears 56 in which a .bearing 57 is mounted to turn. A latch 58 is slidable in the bearing 57 and presses against the brace or radius rod 36, the radius rod 36 having a seat 63 with which the latch 58 cooperates. The latch 58 has a stem -59 slidable in a cap 60 on one end of the bearmg 57. The stem 59 of the latch 58 has a finger plece 62. A compression spring 61 is located within the bearing 57 and within the cap 60 and thrusts the latch 58 against the radius rod 56. The latch 58, thus, acts as a frlctlon grip. A set screw or clamping devlce 64 is threaded in the bearing 57 and adapted to engage the radius rod 56 at the will of an operator.

In practical operation, the water enters by one or more of the couplings 14 and Hows into the body 1, the valves 2O opening to admit the water. lVhen any hose is disconnected at any one of the couplings 14, the corresponding valve 2O closes automatically under the action of the spring 21. The partitions 17 serve to prevent the water from swirling about. as it enters the body 1. The water Hows from the body 1 into the head 23. The head 23 can be turned on an axis represented by the shaft 30 in Figure 1. From the head 23 the water flows by way of the arms 48 into the outlet pipe 49. r1`he outlet pipe 49 can swing on an axis represented by the axis of the part 45 in Figure 4, and, thus, the nozzle 51 has practically a universal movement, since the nozzle can be swung upwardly and downwardly, and be swung around horizontally, as well.

The brake 38 of Figure 1 may be set down,

on the body 1 to hold the head 23 in any position to which it has been rotated, the brake 38 being advanced and set by turning down the threaded stem 40 through the instrumentality of the head 41.

The nozzle 51 can be swung upwardly and downwardly, and the spring 61 of Figure 2 will cause the friction grip 58 to engage the radius rod 36 and hold the nozzle 51 in any position to which it has been adjusted, vertically. When the nozzle is swung down far enough, the member 58 will engage in the seat 63, the part 58 then acting as a latch to limit further downward swinging of the nozzle. The operator, however, can pull back the latch 58, by means of the iinger piece 62, and let the nozzle 51 swing downwardly further than would be the case if the latch 58 were engaged in the seat 63. If the operator wishes the nozzle to be held with a iirmer hold than is provided through the instrumentality of the latch 58, then the set screw or clamp 64 of Figure 2 can be advanced to bind tightly on the radius rod 36.

Especial attention is given to the fact that the body 1, considered as to vertical section, is wedge-shaped as shown in Figure 1, the hose couplings or inlets 14 being at the wider end of the wedge. and the outlet, represented by the member 45, being above the narrow end of the wedge. This construction gives a good width at one side of the device to accommodate hose couplings 14 of large diameter, and, at the same time, brings the outlet, represented by the part 45, down close to the `ground, thereby giving the device stability.

Each of the inlets has its individual valve 20, and the partitions 17 not only prevent swirling, but, also, serve as internal reinforcements for the body 1. The body, therefore, is well adapted to withstand extreme pressures, and water hammer. The several brackets 5 and 9, together with the parts associated therewith, a'ord stability, both as to the mounting `of the device and 4as to its capacityV for resistingl pressure strains and other strains. rIhe shaftBO is useful not only as a means for holding the head 23 `on the body l, but also is useful .as a reinforcing screw 64. It will beobserved that the vnozzle 51 may be swung over from'the position of Figure 6 to the positionof Figure 5, thereby conferring a large degree of adjustability uponthe device. The water entering by way holding ythe head on the body for rotation'as r ofy the hose couplings llproceeds along stra-ight lines to the center of the body l, an arrangement, which, obviously is of great utility in a device of the class described.

Having thus described the invention, what is claimed is 1. In a device ofthe class described, a hollow body having an inlet', a head, means for journa-lling the headon the top of the body for rotation about an upright axis, means for aforesaid, a nozzle carrier mounted to swing vertically on the head, a radius rod, means 1' for mounting the radius rod pivotally `and rotatably at its lower end on the top ofthe head,at apointnear to thecenter of the Y head, and a holding mechanism on the nozzle carrier, wherewith the radius rod is yslidably engaged, the rod having a free end extended headjournaled on the top ofthe body for rotation about anfupright axis, a nozzle carrier mounted to swing vertically on the head,

an outwardly closing automatic check .valve at the inner end of leach of the inlets, the valves being housed in the body, between the partitions, and spring means for closing each valve when :there is no hose on the correspondinglinlet, andwhen the back pressure, incident to the use of such a hose,is removed,

and spring means for closing each of the valves, the said spring means being engaged with the partitions.

In testimony that I claim the foregoing as my own I have hereto aixed my signature.
