NozzLE `Foa ETRE-FIGHTING APPARATUS.

Application nl ed March 9,11909. Serial No. 482,364.

To all whom it may concern:

Be it known that I, MILTON H. HART, a citizen of the United States, residing at New York, borough of Brooklyn, in the o county of Kings and State of New York,

of the delivery end of the nozzle, so that the stream issuing therefrom may be directed to any point desired and maintained at such point with the greatest ease and accuracy.

The preferred embodiment of the invention is illustrated in. the accompanying drawings, wherein Figure 1 is a rear elevation of the. nozzle. Fig. 2 is a side elevation of the same. y Fig. 3 is a detail View partly in elevation and partly in section, showing the mounting for the actuating worm. Fig. t is a horizontal sectional view through the structure. Fig. 5 is a detail sectional View of the structure, showing the actuating worm locked out of r engagement with the worm wheel.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, the nozzle comprises two principal members, namely,

a fixed supporting member 6 and a nozzle member 7. The supporting member 6 may be of any suitable character, bolted or otherwise fastened as shown at 8 to the supply pipe and rigidly mounted against movement. The nozzle member is composed of two sections 9 and 10. ll`he section 9 is suitably journaled in the section` 6 on a substantially vertical axis, and the section 10 has convergently disposed legs 11 rotatably coupled, as shown at 12 to opposite sides of the section 9. `The legs 11 are in mturn coupled to the discharge portion 13 of the nozzle. So far as thus described, no

55 claim is herein made to the structure, the

novelty residing in the means for effecting `the relative adjustment of the parts, and

for holding them in adjusted relation.

For" the purpose of `effecting the rota-tion ofthe nozzle member 7 on the supporting member 6, the following structure is preferably employed. A worm wheel 14: is fixed to and surrounds the supporting member 6, while the section 9 just above said worm wheel 14, has a split collar 15 clamped there- `to.` rlhis collar carries an. outstanding bracket 16 `having depending ears 17 between `and` to which is pivoted a boxing 18. `A shaft 19, journaled in the boxing, carries a worm 2O that is` arranged to mesh with the worm wheel 141, and said shaft furthermore has at one end a suitable operating handle 21. The boxing is also provided `with a depending handle grip 22 and with an upstanding extension 23 that terminates ina locking lug 24. A latch 25 pivoted, as shown at 261 upon the bracket, has a depending lug 27 that is arranged to engage the opposite sides of the lug 24, and thus hold the boxing in different positions, in which the worm 20 is respectively in and out of mesh with the worm wheel, as will be clear by a comparison of Figs. 3 and 5. With this structure, it will be noted that if the 1worm is in mesh with the worm wheel, the member 7 will be locked against accidental rotation on-the supporting section G, but by turning the worm through the medium of the handle crank 21, a minute change of the position of the nozzle member can be effected. By raising the latch 25, and swinging the boxing 18 outwardly, the worm can be disengaged Jfrom the worm wheel and locked in its disengaged position, in which case, the nozzle member can be freely rotated by hand.

The nozzle section 10, as already described, is rotatably coupled on a horizontal axis to the section 9, `and for the purpose of swinging the section 10 in a vertical direction, as well as in a horizontal direction, when the worm 20 is uncoupled from the worm wheel, a handle staff 26is employed having a grip 27 at its rear free end. The sta' is engaged in the depending ear 28 of a split collar 29 that embraces the legs 11, said ear being located between the legs. Said staff preferably passes through the ear, in which it has a slight play but is held against deta ehment on said ear by nuts 29 arranged on `the staff on opposite sides of the ear. The staff also passes through a sleeve 30, pivotally mounted, as shown at 3l to a bracket 32 secured to the section 9. A set screw 33, threaded into the sleeve 30, is movable into and out of engagement With the staff 26 and can be operated by a Wrench 34 or other suitable devi-ce.

Vith this construction, it will be evident that if the set screW 33 is loosened, the nozzle section 13 can be placed at any desired angle of inclination, and can be fixed in the desired position by retightening the set screw. The handle also constitutes means for svvinging the nozzle on its vertical axis When the Worm is disengaged from the Worm Wheel.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled. in the art, Without further description, and it Will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as nevv, and desire to secure by Letters Patent, is

l. VIn a nozzle structure of the character set forth, the combination With a support-ing member, of a nozzle member journaled thereon and comprising a delivery element and convergent legs connected thereto, a sectional collar clamped upon both legs, anda directng handle secured to the collar between the egs.

2. In a nozzle structure of the character set forth, the combination With a supporting member, of a nozzle member pivotally mounted thereon, a sleeve carried ,by the supporting member, a handle connected to the nozzle member and being longitudinally slidable through the sleeve, and means carried by the sleeve and engaging the handle to hold said handle against its longitudinal movement therethrough.
