Patented July 29, 1952 HOSE NOZZLE James S. Bishop, Cincinnati, Ohio Application May 27, 1947, Serial No. 750,799
This invention relates to a hose nozzle and more particularly pertains to one which provides a sprinkling delivery port adjustable tovary the spread of the delivered streams and which also provides an adjustable valve at the hose end for controlling the amount of fluid flowing through the nozzle.
The nozzle is designed to deliver small individual streams of water, or other fluid, to sprinkle gardens, or the like, the side spread of part of the emitted streams being variable by turning a control device at the deliveryend of the nozzle. The throw of the'individual streams is controlled by turning another member of the nozzle, whereby the flow of fluid may be varied to any degree between shut-off and the delivery capacity of the nozzle.
The delivered streams are emitted from a perforated disc in which the holes are arranged in concentric circles, the outer circle of holes having the water delivered therethrough in a selectively directed manner to determine the angle at which the streams therethrough are emitted with reference to the long axis of the nozzle, whereas the inner circle of holes delivers fluid streams therethrough in lines substantially parallel with the nozzle axis.
By provision of such a sprinkling port, a considerable amount of water may be delivered in a sufiiciently distributed manner as to quickly water a garden without damage to the vegetation, without washing or eroding the ground, and without causing the harmful effects present in the use of the spray or atomizing types of nozzles. The adjustable sprinkler head permits aselection of the area to be wetted and the individual streams issuing from the :disc may be accurately directed by properly pointing the nozzle. Adjustment of the sprinkler head in conjunction with adjustment of the valve gives the operator control of the area over which and the force with which the fluid is emitted.
Although the nozzle is intended for use with water, other fluids such as insectides and liquid fertilizers may be used..
The nozzle has a relatively long tube between the valve and the sprinkler head which collimates the stream of water conducted therethrough so as to still any turbulence thereof which is imparted thereto by the passage of it through the hose or valve, so that'the sprinkler head has a straight stream of water directed thereto at all times.
Therefore, an object of my invention is to provide a hose'nozzle having a sprinklingv headadjustable as to delivery angle of the streams and which has a flow control valve separate therefrom.
delivery holes, the delivery of fluid to the outer circle-of holes being controlled by a selecting means so as to selectively direct the angle of delivery of fluid through the outer circle of holes.
Another object of the invention is to provide such a nozzle wherein a collimating tube straightens the water supply stream directed to the sprinkling head.
With these and other objects in view, which will appear in the description and claims to follow, I describe my invention with reference to the drawings in which:
Fig. 1 is a section through the length of the nozzle showing the control valve and sprinkling head in full open position.
Fig. 2 is a view of the substance of Fig. 1, except the sprinkler head end is shown in elevation and the control valve end shown, closed, in section.
Fig. 3 is a. view of the substance of'Fig. 1, except the control valve end is shown in elevation and the sprinkler head end shown with the outer circle of holes occluded.
Fig. 4 is an enlarged detail of the sprinkler disc in front elevation. i
Fig. 5 is an enlarged detail of the sprinkler disc of Fig. 4, in side elevation.
Fig. 6 is an enlarged detail of the valve disc in front elevation.
Fig. 7 is an enlarged view of the valve disc of Fig. 6, in side elevation.
Fig. 8 is a perspective view of ing collars.
' Fig. 9 is a perspective view of the sprinkler disc retaining collar.
In the drawings, the same reference numbers are applied to the same parts throughout the several views. i
I provide a collimating tub 20 having a cylindrical fluid passageway 2| having an input port 22 and an output port 23.
The inputend of tube 20 is threaded externally, as at 24, to receive, adjustably, a hose-coupling piece 25, having threads 26, by which it maybe coupled to the efiluent end of a hose which will abut in a water-tight contact with a resilient washer 21, in the ordinary manner.
Washer 21 rests against the outer edge of valve disc 28 extending across the interior of, the
one of the spaccoupling, its edges being threaded, as at 29, so it may engage threads 26 on the hose-coupling piece 25, said valve disc 28, being screwed into the coupling piece so as to come into contact with a collar 30 which rests, on its other end, against washer 3!, made of gasket fibre, said washer 3| being seated against a shoulder 32 on the inside of hose-coupling piece 25. Washer 31 may be split so it may be slipped over a shoulder 38 on tube 20.
Valve disc 28 has a circle of holes 33 piercing it from side to side between two circles 34 and 35, represented by dotted lines (Fig. 6), the circle 35 having a radius slightly greater than the input port 22 so that, When hose-coupling iece 25 is run onto tube 20 by the operator turning it by knurled portion 36, the disc 28 will be moved from the position shown in Fig. 1, which is the wide open position, to the position shown in Fig. 2 which is the closed position, wherein the central portion 3-! will occlude the input port 22, shutting oif flow of water from the hose to the tube 26. In intermediate positions of the disc 28, the water will flow withmore or less volume, through holes 38, according to the spacing of diSc 28 from the end of tube 26. W'asher 31 engaging shoulder '38 ofthe' tube when :the valve'is full open prevents the backing ofi of the hose-coupling piece 25 from tube :25.
At the delivery end of the nozzle an adjustable sprinkler head as is provided with internal threads which permit ittobe screwed on external threads '41, on the delivery end of tube 2 ii, said head being moved by the operator turning it by knurled portion 42. Split 'fibre gasket lie-limits the movement .of head 4i) in an outwardly direction by coming to rest against shoulder 4% of tube 20.
iHeld across the interior of the head it is sprinkler disc 45 held against a collar'fi, similar to collar 30, before described, which, in turn abutsagainst gasket 43. 'Disc Afr-is :heldin place by retaining ring 4! having external threads '48 'mating with internal threads in the forward end of head Gil. Retaining ring 41 has grooves 49 and 59 to aid in it insertion and removal,
whereby the sprinkler disc '45 may be removed and'reinstalled, for cleaning purposes.
The sprinkler disc has its central, pierced, portion curved inwardly, as shown in Figsgl, 3 and 5, the holes therein consisting of a central h01e'5'l (Fig. 4), an inner circle. of six h01es'52, and an outer circle oftwelveholes 53.
For ordinary 'use with half-inch garden hose, the diameter of tube passageway 2| should be about three eighth's or an inch and its lengthtwo and one-half inches. Under such circumstances the disc 45 should be made of stock aboutfifteenthousandths of an inch thick and the centers of the inner circle of holes should be onja-circle having a radius slightly less than 'thera'dius of -tube 20 so that they are within the walls of the tube passageway, at the delivery end when the head 40 is screwed down to its innermost limit as shown in Fig. '3, thus preventing passage of water-through any excepthole 5| and holes 52 pass through all the holes in the sprinkler disc.
The directional influence of water being turned by the disc toward the outer circle of holes is retained by the streams issuing from the disc through the outer circle of holes and cause fSllOh streams to be directed outwardly, such out- 5 4 ward angle being more pronounced as the disc moves inwardly toward port 23.
The holes 5|, 52 and 53 should be about onesixteenth of an inch in diameter and the holes 33 in the valve disc should be about one-eighth in diameter, which will give the sprinkler disc a discharge area, when full open, about sixty percent of the area of the holes in the valve disc. This assures maintenance of pressure within the nozzle, to cause the issuing sprinkling streams to be forced to a distance useful for gardening purposes when used with ordinary hydrant pressures. Such dimensional factors may be adjusted to suit the conditions under which the nozzle is used.
Brass or equivalent material is preferred for the parts of the nozzle other than the gaskets. and washer.
In use, the operator adjusts the flow of water through the valve by turning the tube 26 by means of knurled portion 60 and adjusts the type of sprinkling pattern by turning sprinkler head 40. j 7
I am aware that variations may be made in regard to some of the things-specified without departing from the principle of the invention, and therefore, I claim my invention'broadly as indicated by the appended-claims.
Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent, is:
