INVENTOR.
Patented Sept. 22, 1936 v UNITED STATES PATENT OFFICE FLUID DISCHARGE DEVICE Horace R. Barker, Springfield, Mass. Application December 6, 1935, Serial No. 53,177
2 Claims. (01. 299- 113 This invention relates to improvements in apparatus for discharging fluid and is directed more particularly to improvements in nozzle devices to be used in connection with firefighting 5,1; apparatus or the like.
The principal objects of the invention are,
directed to the provision of water discharge apparatus which is particularly adapted for use in connection with fire fighting apparatus, the
' same being characterized by means adapted to facilitate the discharging of a smooth stream of water over a greater distance than is-possible by apparatus now in' common use.
In connection with fire-fighting apparatus it is desired to deliver a smooth stream of water over a considerable distance or height at a considerable pressure. With present day apparatus it is more or less difficult, if not impossible, to discharge a stream at the desired pressures for the height or distances desired and necessary. This is due to the fact that the water in passing through the nozzle is swirled, rolled, or becomes turbulent so that the discharged stream swirls, rolls or becomes turbulent and consequently fans out, brooms or breaks. This reduces its effectiveness since of course a smooth, well-defined stream at the desired pressures is necessary for the greater distance or height.
According to this invention means is provided within the nozzle or water-discharge means which tends to eliminate the turbulent rolling or whirling action of the water during its passage therethrough so that there is discharged from the discharge outlet a smooth, uniform 5 stream which by reason of its novel characteristics I have found will carry a greater distance at the desired pressures than is possible with present day nozzles. In this way the nozzle at the end of a hose, stand pipe, or other apparatus, more effectively discharges water. This is accomplished by the provision of means in the form of plates in the water passage which are disposed so that they are substantially in parallelism with the axis of the water passage 5 thereby.
Many and various other novel features and advantages of the invention will be hereinafter more fully referred to in connection with the accompanying description of the preferred form thereof. reference being had to the drawing wherein:
Fig. l is a longitudinal sectional view through a water discharge apparatus having the novel features of the invention associated therewith;
Fig. 2 is a cross-sectional View on the line 2-2 of Fig. 1; and p Fig. 3 is a similar view on the line 3-3 of Fig. 1.
Referring now to the drawing more in detail, the invention will be fully described.
A base is shown at 2 and this may be of the Siamesetypehaving separate water passages 4 and 6 which converge into a throat indicated generally by 8. p V
The base 2 may-take any form desired since it is not desired to be limited to the particular form shown. It will be understood that the base shown or anyequivalent structure will be providedwith athroat such as 8 on its upper or outerend. I
A' nozzle member is indicated by I6. This nozzle member may be carried by the base and in the form of the invention shown it has its lower or inner end in threaded engagement with the outer or upper end of the base member 2.
The nozzle member it! has a discharge outlet i2 at a more or less distance from a throat or barrel portion Hi. The discharge outlet I2 is preferably somewhat less in diameter than that of the throat l4 so that a water passageway l5 converges from the throat M to the discharge outlet l2.
The throat I 4 of the nozzle member is somewhat less in diameter than that of the throat 8 of the base so that a water passageway I5 is provided which converges as shown.
In the throat 8 there are provided a plurality of relatively thin plates or vanes 2 and 2| which extend transversely of the said throat. These provide a plurality of passageways 22 therebetween. These plates 20 and 25 are arranged so that the plane of their surfaces are in substantial parallelism with the axis of the throat 8. The plates 20 and 2| may be secured together and associated with the throat in any desired manner. For instance the plates may be slotted so as to be interlocked like the partitions of a box.
In the form of the invention shown, the plates 20 and 2| are associated with a sleeve 24 which is disposed in the throat 8 and said plates may be secured to this sleeve 24 in any desired and well known manner. V
The throat M of the nozzle member has a central tube member 30 associated therewith and plates 32 and 34 extend transversely of the throat so that there are provided water passages 36 around a central passageway 38.
The central tube 30 may be supported by or associated with the plates 32 and 34 and as in the former case the tube 30 and plates are disposed in a sleeve 43 inserted in the throat Hi. In accordance with the invention the plates 32 and 34 and tube 39 may be connected or associated in any convenient way but it is preferable that the plates and tube be arranged in substantial parallelism with the axis thereof.
As water is delivered to the throat 8 of the base 2 its tendency to swirl or become turbulent is overcome by the plates 29 and 2| forming the passageways 22 through which the water travels. The plates 20 and 2| are of considerable length. As will be seen the plane of their surfaces is substantially parallel to the axis of the throat so that water is guided in a straight path and as it passes through the tapering passageway 15 into and through a throat I4 of the nozzle member it is again brought into contact with the plates 32 and 34. As it travels through the central tube 30 and passageways 36 formed by the plates 32 and 34, its tendency to swirl is overcome. The water, being controlled as it is, will, on' being discharged from the discharge outlet l2, emerge as a smooth uniform stream which does not have the objectionable swirling, rolling or turbulent tendency which would result in fanning out or breaking. Thereby it is possible to discharge a stream of water at the desired pressure and velocity which will carry over the relatively long distances or heights desired.
' The invention may take various forms and various modifications may be made therein without departing from the spirit and scope thereof. Therefore it is desired to be limited if at all by the appended claims rather than by the foregoing description and what I desire to claim and secure by Letters Patent of the United States is:
1. A water-discharge apparatus comprising in combination, a body member formed to have a pair of separate water passageways converging into a unitary throat portion, a tubular member extending forwardly from said throat portion as an extension thereof, a plurality of substantially parallel plate members disposed in said throat in substantial parallelism with the plane of the axis thereof and another plate member associated with the first-named plate members at substantially right angles thereto, a central tube disposed within said tubular member axially thereof, and plate members extending transversely of said tube between the same and said tubular member. 7
2. A water-discharge apparatus comprising in combination, a body member formed to have a pair of separate water passageways converging into a unitary throat portion, a tubular member extending forwardly from said throat portion as an extension thereof, a plurality of substan tially parallel plate members disposed in said throat portion in substantial parallelism with the plane of the axis thereof and extending between the inner walls thereof, another plate member associated with the first-named plate members at substantially right angles thereto and extending between the inner walls of the throat portion, a central tube part concentrically disposed within said tubular member, and plate members extending transversely of said tube between the same and said tubular member.
