This invention relates to a hose nozzle of the type show-n in my Patent 1,855,888, April 26, 1932. The hose no-zzle illustrated in said patent comprises a nozzle member having a duct therethrough and a combined valve and spray device which is adjustable on said nozzle member so as to occupy either a position in which it closes the duct and thus acts as a valve device, or into a position in which it opens the duct and acts as a spray device to break. up the stream of water into a spray. Such combined valve and spray device is also pivotally mounted and is capable of swinging laterally about its pivot into a third position in which it is entirely out of register with the duct so that the water will issue from the duct in a solid stream. In said patent, the adjusting movement of the combined valve and spray device is accomplished by the rotation of a sleeve which surrounds the nozzle member.

One of the objects of the present invention is to provide certain improvements in the nozzle described in my said patent by which, when the sleeve is operated to open the nozzle, the combined valve and spray device will be automatically turned on its pivotal connection and thus swung into its inoperative positionv in which position the duct is open for the Vdischarge of the water as a solid stream.

A further object of the invention is to provide a simple means for adjusting the combined valve and spray dev-ice into its spray-forming position.

Other Objects of the dinvention are to improve the hose nozzle described in said patent in various other ways which will be more fully set forth hereinafter.

In the drawings wherein I have illustrated a selected embodiment of the invention Fig. 1 is a 'longitudinal section through a hose nozzle made in accordance with the invention and showing the nozzle in its closed position with the combined valve and spray device closing the duct.

Fig. l0 is a View of a supporting `collar or ring adapted to receive a strap for supporting the nozzle from the shoulder.

Fig. l1 is a fragmentary sectional view showing a modified construction in which the Valve l is provided with a soft seat.

The nozzle herein shown comprises a nozzle member l .provided with an axial water-delivering duc-t 2 and having its base end 3 provided with interior screw threads i adapted to receive the exterior screw-threaded portion 5 of a hose 6.

The combined valve and spray device .is indicated at l. This device is shown as formed on the end of a stem $3 which is carried by two arms 9, each arm having the straight guiding .portion l5 extending parallel to the axis ,of the duct 2 and the inclined portions Il leading to the stem 8 and on which the stem is supported. If desired, the valve `l, stem 8, and arms S may all be made as an integral structure. The valve portion l is of a size to close the duct 2 by seating against a valve seat l2 at the end of the duct.

The inner ends of the arms 9 are pivotally connected to a nut member i3 which is screwthreaded to the nozzle member l, the latter having the exterior screw-threads le for this purpose. Surrounding the nozzle member l is a controlling sleeve l5 which is capable of rotation on the nozzle member, said sleeve being shown as having a screw 'i6 extending therethrough, the inner end of which operates in a groove Il formed in the nozzle member l. This allows the sleeve to be rotated freely about the nozzle member but prevents any movement of the sleeve .on the nozzle member in the direction .of the axis thereof.

This sleeve l5 Vis formed with two .grooves or guideways i8 in which the straight portions l B of the arms S are received and operate. The inner ends of the arms 9 .are shown as being provided with trunnions .i9 that are received in .recesses formed in the nut Ymember i3, .and since the straight portion ofthe .arms 9 `are Ireceived in the grooves i8, the turning of the sleeve l5 on the nozzle member will operate through the arms 9 to turn the nut 'i3 on the nozzle member and thereby move said nut Aaxially on the nozzle member.

When the parts are in the position show-n in Fig. 1 Vthe valve 'l is resting against the valve seat The device as thus far described is quite similar to that illustrated in my aforesaid invention, Pat. No. 1,855,888.

One feature of my present invention relates to novel means which act automatically as the sleeve I5 is turned to swing the combined valve and spray device on its trunnions I9 into a position entirely at one side of the duct 2 as shown in Fig. 3 so that the water will be delivered from the duct in a solid stream which is indicated by the dotted lines 20.

For this purpose, I have provided two spring pressed plungers 2l which are carried in recesses 24 formed in the nozzle member I, which plungers act against the straight portions I9 of the arms 9. Each plunger is backed by a spring 25 and each spring and its plunger are retained in its recesses by the screw-threaded plug 26 as best seen in Fig. 7.

The nozzle element I is provided at its outer end with a stop collar 21 which is screw-threaded thereto and which serves to limit the outward movement of the nut I3.

. One wall of each groove I8 is cut away at its outer end as shown at 28, the construction being such that when the nut member I3 has been moved to its-outer limit as determined by the stop collar 21, the combined valve and. spray device can swing about its trunnions i9 into the dotted line position Fig. 7 or fullvline position Fig. 3, thereby removing the valve member 'I entirely from the line of the vduct 2.

When the sleeve I5 is turned to shift the nut member I3 and the combined valve and spray device toward the right from the position shown in Fig. l and said combined valve and Spray device reaches theposition shown in full lines 7, the springs 25 will operate automatically to swing the arms 9 laterally about their trunnions I9, thus swinging the Valve device l out of register with the duct 2 as shown in full lines in Fig. 3. The springs 25 then function to retain the valve device in its inoperative position so long as the nut member I3 is in its extreme position against the stop member 2l. This is an improvement over the construction shown in my Patent 1.855.888 because in said patent. there is nothing to hold the valve device in .its inoperative position when the nut member is fully advanced. and if the nozzle of said patent were being used in connection with re apparatus, the swingingr movement of the nozzle to play the water on the lire would be Vapt to cause the valve member to swing from its inoperative position to its sprayingV position so that the stream of water delivered from the nozzley would be changing from a solid stream to a spray and back to a solid stream. again due to the free swinging movement of the valve device resulting from a movement of the nozzle .in directing the water to different portions of the fire. With my improvements, however, when the nozzle is rst opened up, the springs 25 will ensure that the nozzle will deliver a solid stream of water and this solid stream will be maintained regardless of any movement which the fireman may give to the nozzle in playing water on the fire.

Another feature of my invention relates to a novel means for shifting the valve device from its inoperative position shown in dotted lines, Fig. 7 and in full lines Fig. 3 into its operative position to produce a spray as shown in full lines Fig, '7 and in Fig. 2.

The sleeve I5 has a guard sleeve 29 rotatively mounted thereon and this guard sleeve is provided with an inwardly directed nger 30 which is adapted to engage one of the arms 9 as the sleeve 29 is turned on the sleeve I5. As herein shown, the sleeve I5 is provided at its outer end with exterior screw-threads 3| which have screw-threaded engagement with interior screwthreads 32 with which the guard sleeve 29 is provided so that the guard sleeve 29 can be turned on the sleeve I5. The screw-threaded flange 33 of the guard sleeve is out away as shown at 3d in Fig. 6 and the sleeve I5 is provided with a stop screw 35, the head of which operates in the said cut-away portion 34. This stop screw 35 permits a partial rotative movement of the guard sleeve 29 on the sleeve l5, the extent of such rotative movement being limited by the engagement of the screw 35 with the walls 36 of the cut-away portion 34. When the guard sleeve 29 is in the position relative to the sleeve l5 shown in Figs. 5 and 6, the iinger 30 will be in its inoperative position so that as the combined valve and spray device is moved outwardly to the outer limit of its movement as shown by full lines Fig. '7, said device will be permitted to swing about its trunnions, thereby to place the valve 'i in its inoperative position shown in dotted lines Fig. 7.

The nozzle will then deliver a solid stream indicated at 29. If it is desired to change this solid stream into a spray, all thatis necessary is to turn the guard sleeve 29 from the position shown in Fig. 5 to that shown in Fig. 4. During such turning movement, the finger 39 will engage one of the arms 9 and will swing the combined valve and spray device from its inoperative position shown in dotted lines Fig. '7 into its operative position in which the valve is in the axial line of the bore 2 but is spaced from its valve seat as shown in full lines Fig. 7 and as also shown in Figs. 2 and 4. The stream of water issued from the duct 2 will then engage the valve I and will be broken up thereby into the form of a spray as shown by dotted lines 43 in Fig. 2

With the present improvements, the opening of the nozzle by rotating the sleeve I5 will automatically swing the combined valve and spray into its inoperative position whereby a solid stream will be delivered by the nozzle, and the change from a Solid stream to a spray can be effected by simply turning the guard sleeve 29 through a slight angle to shift it from the position shown in Fig, 5 to that shown in Fig. 4.

The nut member I3 is shown as having two slots 91, one on each side thereof in which the trunnions i9 are received. These trunnions are retained in the closed ends of the slots by means of a retaining ring 38 which is screw-threaded to the screw-threaded portion 39 of reduced diameter with which the nut I3 is provided. This construction furnishes a simple means for assembling the combined valve and spray device with the nut i3 and of separating said device from the nut when it is necessary.

The guard sleeve 29 is shown as having a ring lli) of rubber encircling the same rod to provide an end grip by which said guard sleeve can be radially turned for the purpose of converting the solid stream delivered by the nozzle into a spray.

indicates a supporting ring mounted on the nozzle member l and adapted to turn -freely thereon, said ring having an extension i provided with a slot 52 to receive a supporting strap by which the nozzle may be supported from the shoulder of a iireman.

In Fig. il there is shown ya construction wherein a soft seat is provided for the valve ll. En this embodiment the nozzle member i is provided with a recess at its outer end in which is received a valve seat member 5I of rubber or some soft metal. valve sea-t member is retained in place by the stop member Zia which, in this embodiment, is provided with the hub extension iid having exterior screw threads that are adapted to engage interior screw threads formed in the end of the nozzle member l.
