T 0 all whom t vmay concern.'

Be it known that l, lVrLLiAM J. MAR- SHALL, a citizen'of the United States of America, and a resident oi' East Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Fire-Hose Nozzles, of which the following is a specification.

This invention relates to fire hose nozzles and has for its object the provision of a device of this character by which a direct stream of water may be directed `upon the iire, or a plurality of smaller streams may be discharged in various directions, either with or without the direct stream in action.

Another object of the invention is to provide such a device with rearwardly extending discharge openings through which streamsmay be directed onto the hoseman or hoseinen, whereby these men may be thoroughlydrenched when subjected to intense heat.

A further object of the invention is to provide these rearwardly extending discharge openings with valves, whereby said openings may be closed when desired.

The invention consists of a casing having a valved nozzle of any well known construction mounted on its outer end, to dis-- charge a main direct stream, combined with y a revoluble member having a plurality of v inafter given.

smaller discharge openings through which additional smaller streams maybe discharged in various directions.

The invention further consists in novel valve mechanism by which said revoluble member may be placed in and out of action at will.

The invention further consists of novel means for controlling the discharge of water through the rearwardly extending discharge openings.

`The-invention further consists of-certain novel features of construction and arrangement of parts which will be understood readily by reference to the description of the drawings and to the claims to be here- For the purpose of illustrating the invention, one preferred form thereof is shown inV the drawings, this lformhaving been found to give satisfactory and -reliable results, Valthough it is to be understood that the various instrumentalities Vof which the invention consists can be variously arranged .and

Qlganzed, that?. the invention is not sei-iai No. 657,340.

limited to the precise arrangement and 0rganization of the instrumentalities as herein shown and described, except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents a longitudinal section of a lire hose nozzle embodying the principles of the present invention. y

Figure 2 represents a`n inverted plan of the revoluble hollow member for discharging a plurality of small streams in various directions.

Figure 3 represents a vertical section of a portion of the casing and the slidable valve therein for closing the lateral ports in said casing.

Figure t represents a horizontal section, on line 4, ,4 on Figure 3, with the slidable pins of the valve cross member in retracted position, and

Figure 5 represents a similar view with the ends of said pins disposed in sockets in the inner face of the valve member.

Similar characters indicate like parts throughout the several figures of the drawings.

In the drawings. 10 is a casing, one end of' which is provided with the internal thread ll by which it may be secured to the lire hose.

The opposite end of the casing is provided with an external thread l2 b v which a valved nozzle 13 may be secured thereto.

Any well known form of nozzle 13 may be used, such, for instance, as the Callahan nozzle illustrated in the drawings.

The main stream of water from the lire hose is discharged through this nozzle 13.

Usually when a lire has been located in a cellar or some similar place, it has been found necessary, or at leastdesirable, to substitute for the direct main stream a plurality of smaller streams which may be directed in various directions.

Generally when this is done, the main nozzle is remo-ved from the casing and another forin of .nozzle is substituted therefor. It isa great disadvantage to be obliged to take time. to makeY these changes as, in the meantime, the lire will be making headway. aiid possibly to such an extent as to. get beyond control.

As a consequence, ithas been found advantageous to mount permanently upon the nozzle casing an additional nozzle member 14 which may be usedpin connection lwith the main stream nozzle 13, or independently thereof.

This additional nozzle member 14 is hollow and is revolubly mounted upon the casing opposite to a plurality of lateral ports 15 therein, one end ot said member contacting with a peripheral flange 16 on the casing 10 and the opposite end thereof contacting with the end of a cylindrical eX- tension 17 to saidcasing.

The inner end of theextension 17 and outer coacting end of the member 14 are each provided preferably with annular raceways in which are disposed a plurality of anti-friction members, such as the balls 18 shown in Fig. 1.

The member 14 has a plurality of projections extendine therefrom at different angles, each of vhich has a discharge opening therethrough.

Of these projections, a portion thereof, namely the projections 19, extend toward the front at an angle to the axis ot the casing 10, while the projections 20'eXtend angularly toward the rear.

Another set of projections 21 4are disposed midway of the length of the member 14 and Veo are substantially tangential to the inner face thereof, so thatthe water being discharged therethrough will cause the hollow member 14 to be rotated about the axis of the casing 10. thereby throwing the streams in every direction.

The projections 20 have discharge openings 22 therethrough, each of which is adapted to be closed by the rotatable valve 23 therein. l

The valve 23 has secured to one end a collar 24, provided with a wing projection 25 by which the valve 23 may be moved about its axis to open the discharge opening 22.

The opposite end of the valve plug 23 has secured thereto a bevel gear 26 meshing with an annular gear 27 surrounding one end of the hollow member 14.

By means of this construction, when one valve 23 is o'pened, the other valves 23 will be opened simultaneously, and likewise all of them willV be closed at the same time with-V out regard to which actuating device 24, 25 is moved by the operator.

Obviously, the discharge of water through these openings may be regulated by movement of the valves 23 so that a full stream may be dischargedV through the openings 22, or any lesser amount as desired.

Then the hosemen are being subjected to. intense heat, these valves 23 will be opened to allow streams to be discharged over the hosemen to keep them thoroughly drenched.

Then the hosemen are lighting a cellar fire and the nozzle is extended through an opening cut in the floor, these valves 23 will preferably be open. 1

When, however, the heat from the re is not so intense as to inconvenience hosemen, thevalves 23 may be closed and 'streams discharged only ;trom the openings through the projections 19, 21.

At this time the main stream through the nozzle 13 may be in action or not, according to the nature of the fire being fought.

Where the nozzle is being used at some distance from the fire, it is desirable to place the `member 14 entirely out o -action and permitthe entire supply of water to pass through the nozzle 13.

The means for accomplishing this result is as follows:

To a 4flange 28 on theinner face of casing 10 is threaded one end of a tube 29, the opposite end of which is provided with a valve seat 30.

This tube 29 is spaced from the inner face of the casing 10, thereby forming an annular chamber in which the tubular valve member 31 is adapted to be reciprocated endwise.

This valve member' 31 has on its inner. tace midway of its length, an 'inclinedshoulder 32 adapted to coact with the yvalve seat 30 to prevent .leakage at this point, and on the outer face of said valve member 31 is an inclined shoulder 33 adapted to coact`with the valve seat 34-on theouterend of the extension 17 of the casing 10.

The valve member 31 hasa plurality of lateral ports 35 which are adapted to register with the ports 15 in the casing 10 when the j valve member 29 is moved outwardly as in Fig. 3.

lhen the valve member 31 is in the .position shown in Fig. 1, the ports 15 are closed thereby, and no water can beadmitted to the hollow member 14, and the shoulder 32, 33 will be in contact with the valve seats 30, 34 so that there can be no leak-age into the hollow member 14.

Then the valve member 31 is moved outwardly, the ports 35 will be brought into Va position beyond the Vvalve seat 30 and opposite the ports 15 inthe casing 10, and the water passing through the casing -10 will then pass through the ports 35, 15 into the cross bar Y38V extending diametrically of vtheV bore of Athe valve member 31. Y

This Cross bar 3e has, a Cynndnen @peeing therein midway of its length, through which Y Y extends-the.threaded outer end 40 of the krod n. Y

The Y threaded rend 40 has clamp i nuts 42 thereon by lwhichsaid rod 41 may be clamped f therein. Y

tosaid cross bar 'when `properly positioned 1 The vSinnen1p-ing am@ iin* are pagina Y indicated in Fig. 4 v'vhentheV cross bar38is assembled in the valve member 31, and when the cross bar 38 is properly positioned in said valve member 31, these pins 37 are moved outwardly in said cross bar 38 until their outer ends are positioned in the sockets 36.

When thus assembled, the cross bar 38 may be oscillated freely about the axis of said pins 37.

When the pins 37 have been moved outwardly, the threaded end 40 will be inserted through the opening in the cross bar 38, and the :nuts 42 thereon clamped against said cross bar.

This threaded end 40 when positioned in the cross bar 38 will retain the slidable pins 37 in their outward position and prevent their ends from being displaced from the sockets 36.

The opposite or inner end of the rod 41 is connected by a pin 43 to the outer end of a crank 44 secured by a pin 45 to a shaft 46 extending through a stutling box 47 in the l side of the casing 10.

The outer end of the shaft 46 has a crank actuating member 48 secured thereto by a pin 49, said member preferably being in the form of a disk as shown in Fig. 1.

The disk 48 has a depression 50 in its inner face into which normally extends the outer end of a locking bolt 51 forced outwardly by a spring 52 in a socket 53 in a boss formed upon the casing 10.

When the valve member 31 is in the position indicated in Fig. 1, the bolt 51 will extend into thedepression 50, thereby preventing the rotation of the crank shaftr46 and retaining the valve member 31 in its closed position.

In the depression 50 is mounted the head 54 having a stem 55 extending outwardly, with a pad 56 mounted on the outer end thereof, said pad being `spaced from said disk a distance equal to the length ofthat part of the bolt 51A which is disposed in the depression 50. y v

When it is desired to slide the valve member 31 into its open position, the operator presses upon the pad 56 and releases the bolt 51 from the depression 50 so that the disk 48 may be rotated about the axis of the crank shaft 46, thereby moving the crank 44 into a position diametrically opposed to that shown in Fig. 1, and through the rod 41 moving the valve member 31 endwise.

This makes a very simple form of nozzle for fire hose which may be used in a variety of ways to suit different conditions.

It is believed that the. operation and many advantages of this improved nozzle will be understood readily without further descrip* tion.
