` 6 Claims. (ci. 299-118) This invention relates to a nozzle for fire extinguishers.
It is an object of this invention to provide an extinguisher nozzle'which can, at will, discharge a fluid as a solid stream projected to a considerable distance, with a minimum loss of head within the nozzle, or which can be made to discharge a spray with a deinite and uniform coverage.
Three forms of the invention are shown in the accom panying drawings, in which Fig. l is a longitudinal cenf tral section of the device on the lines 1-1 0f Fig. 3Q
Fig. 2 is an exploded View of the valve mechanism and Fig. 3 is an end elevation of the device. i Fig. 4 is a central longitudinal section of a modification of the device. Fig. 5 is a central section of a modified form of the invention. Fig. 6 is an end elevation of the same, from the discharge end of the nozzle and Fig. 7 is a side elevation of the control element of the device of Fig. 5.
Referring now to Fig. l. The numeral 10 represents a casing having at the right hand side a threaded socket 11, in which is screwed a nipple 12 adapted to be connected with a source of liquid supply, as for example, a tank lled with a re extinguishing liquid.
The casing has a vertical bore providing at the top a cylindrical slide bearing 13 for a pin'14 and a central rectangle chamber 15and a lower cylindrical slide bearing 16 for a pin 17. The pin 14 engages a handle 18, pivoted at 19, and the pin 17 has a collar 2t) between which and a cap 21 at the bottom of the bore is coniined a compression spring 22. A at valve 23 of a suitable plastic such as Teon slides in the chamber 15, conned between the pins 14 and 17.
The valve 23 has a central opening 24 in position to register with a central opening 25 in the side of the chamber 15 (which comprises a valve seat) in the upper position of the valve and with a lower opening 26 in a lower position. A spring 27 conned within a cavity 28 in nipple 12, presses the valve against the side of the chamber 15. A gasket 29 surrounds the pin and is held in compression by a plug 31. VThe casing has an outwardly extending nozzle shaped extension 32 surrounding the opening 25, and an outer wall spaced from the extension and forming between them an annular chamber 33, communicating with the chamber 15 by opening 26 in the chamber wall.
An outer control member 35 lits against the side wall to close the chamber 33 and is held against the edge of the side wall by a hollow nut 36. This control member has a central bore 37 which rits against the nozzle member 32, to form a continuous channel with opening 25 for a jet discharge. The control member also has two channels 33, one on each side of the central bore 37, affording a discharge passage from the chamber 33 to the discharge end of the nozzle. These channels have their axes inclined toward each other so that the streams issuing therefrom will impinge upon each other.
Within each of these channels 38 is situated a spiral member 39 provided with helical vanes 40 past which any Patented Sept. 4, 19,56
ice
stream issuing from the channels 38 must pass, to be set into rotation thereby. Each channel 38 is tapered inwardly as shown at 40a beyond the vane member to condense Vthe rotating jet formed by the vane member.
The outer, or discharge, face of the nozzle has a central opening 41 through which the jet discharge may issue, and it is provided with openings 42 on each side of the central opening through whichthe rotating, or spray jets from openings 3S are discharged. These latter openings are provided with flared recesses as shown at 43 elongated at an angle to the horizontal, and at an angle to the common center line between them. In this manner the spray is shaped to the maximum advantage. Each spray is elongated from a conical shape by the recessed openings, and the jets impinge upon each other in a manner to shape the coverage area to the maximum advantage.
Referring now to Fig. 4 the numeral 5t? represents a casing having at the right hand side a .threaded socket adapted to be connected to a source of liquid supply, in this case a tank iilled with a re extinguishing liquid not shown here. The casing has a vertical bore 51 provided with an inwardly projecting shoulder 52 near thel top, and closed at the bottom by a screw threaded cap 53 having a recess as shown at 54 to receive a spring 55.
A plunger 56 slides snugly within the bore 51 and has a hole through it in alignment with the groove 61, and
into this hole is threaded a nipple 62. The casing is also provided with a discharge head 63 surrounding the nipple 62 and tting within the hollow stud 64, and held thereon by a nut 65.
This discharge head 63 has a central bore 66 in alignment with the bore of the nipple 62, to form a continuous discharge passageway with it. This socket has Vtwo other bores 67, one above and one below the bore 66, both of which taper toward the front, to provide nozzle openings 68. y Y
As will be seen from the drawing, the nozzle openings 68 are on a center line inclined tothe vertical and the outer face of the head 63, at the opening 68 it is cut away to provide a ilared opening which is ilared more in one direction than the other, and these lines of maximum ilare are themselves, at an angle to the lines connecting the center lines.
With either of the foregoing constructions, when the valve 23, or the plunger 56, is in the position shown in the drawings, a solid stream is projected out of the bore- 41, or 66, to a considerable distance. If, however, the
alignment with the openings 34, or 72, then the solid stream is cut ott, and the uid is discharged past the jet spirals 39, or 69, and out through the lateral nozzle openings. Before reaching the nozzle openings,l however, the stream in each boreihas reached a high rotational velocity which would normally discharge a cone spray from each opening, however, such a cone sprayv alone is apt to be hollow. With the arrangement here shown, the spray from one of the openings striking the spray from the other opening tends to lill in the center ofthe cone, to give more uniform disposition over the entire area.
Moreover, because the two channels 38, or 67, are inclined to the vertical and toward each other, there is a greater lateral distribution compared to the vertical.
This distribution is further affected by the elongated flares at each opening.
In Figures 5, 6 and 7 there is shown a modied form of the device, in which the numeral 110 represents a casing having a socket 111, by which it may be attached to a hose H, or the like. The other end of the casing has a bore 112 to receive a hollow control element 113, and this bore 112 is threaded at 114 to receive the discharge nozzle 115, which may be used to hold the control element 113 in place.
The casing 110 is provided with a central borc 116, transverse to its axis, to provide a sliding t for a plunger valve 117. A spring 118, conned within bore 116 by a cap 119 urges the plunger 117 upwardly, and an annular shoulder 120 within the bore 116, engages a shoulder on the plunger to limit its upward movement. The plunger has an extension 117a, extending out of the casing, in position to be engaged by an operating lever. The extension has an annular recess to receive a packing washer 117b.
The bore 116 communicates with the socket 111 at 121, on one side, and it is provided with two openings 122, and 123, into the inner end of the bore 112. One of these, 122, is threaded to receive the inner threaded end 124 of element 113, thus providing a continuous smooth passage 125, from bore 116 to the end of the element 113 at 126.
The control element 113 is generally tubular but its tubular portion is much smaller in diameter than the bore 112 and a series of inter-fitting spiral anges 127 extend from the outside of the tubular portion to the wall of the bore 112. These spiral anges, however, do not extend to the end of the bore 112, leaving an annular chamber 128 affording communication to all the spiral passages defined by the ilanges. A similar annular chamber 129 is provided at the other end of the spiral anges, and as shown, the outer diameter of the control element 113 is reduced in diameter within the chamber 129, in which the liquid may rotate at considerable speed.
The plunger 117 is provided with a circumferential recess 130, affording a passageway between openings 121 and 122. The opening 123 communicates with the chamber 128, and the opening 121 is large enough to admit liquid to the recess 130 in both the upper and lower position of the plunger.
The discharge nozzle 115 is provided with a central discharge opening 134 which flares outwardly at 135, and which flares substantially up to the diameter of the chamber 129 on the inside. As will be seen, this are 135 is elliptical so that the spray issuing from the nozzle may have a greater lateral spread, compared to the vertical. While the discharge nozzle is here shown as ared, it is possible to employ an orifice in a thin metal wall without the are, although the discharge cannot be so well controlled.
The handle 136 is pivoted to the casing 110 at 137, in position to engage extension 117a.
With the handle 136 in the position shown the fluid is discharged through the passageway 125 and projected through the opening 134 as a solid stream. lf, however, the handle 136 is depressed the passageway 122 is cut off, and the uid is discharged through passageway 123 past the spiral anges, and assumes a high rotational velocity within the chamber 129. It thus passes through the opening 134 as a cone. This cone has a greater lateral spread than vertical because of the shape of the flared opening 135.
What I claim:
l. A nozzle for projecting a stream, or spray, comprising a casing having a bore therein, a straight unobstructed jet channel extending from said bore to a jet outlet, said casing having also a pair of spray channels having free spray outlets situated on opposite sides of said jet outlet, each having means to cause rapid rotation of fluid within the spray channels about the axis thereof to produce a spray from each spray outlet, and means for connecting either said jet channel or said spray channels with said bore.
