Description
Patented Dec. 14, 1943 UNITED STATES PATENT OFFICE NOZZLE Kenneth A. Bevington, Evanston, Ill., assignor to- American'Molded Products C0,, Chicago, 111., a corporation of Illinois Application May-26, 1942, Serial No. 444,557
2 Claims. (01. 299-139) The present invention relates to liquid discharge nozzles of the type adapted to be connected to a section of flexible hose. More particularly, the present invention is directed to improvements in nozzles of the type wherein the valve member may be quickly and easily manipulated by the same hand of the person, which isto hold the nozzle.
Nozzles of this general type are especially-suitable for use in connection with various'types' of portable equipment, such as used for sprayingand watering of orchards, nurseries, gardens, etc'., or in connection with emergency fire control-apparatus.
One of the objects of the presentinvention is to provide an improved nozzle of the character indicated, which is characterized by the provision of a reciprocably movable valve member adaptedto be quickly and easily manipulated for controlling the form of discharge of the liquid'through the nozzle.
Another object is to provide an improved'nozzle of the character indicated, wherein the valve member is reciprocably movable to either of two positions of adjustment, one serving to produce a liquid spray and the other a liquid stream.
A further object is to provide an imprVed'n0Z'-- zle construction of the character indicated, wherein the valve member is in the form of an apertured plate adapted to be moved transversely relative to the axis of the discharge orifice, and wherein said plate is adapted to be directly manipulated by a finger of the operator for controlling the discharge of liquid therethrough.
Still another object is to provide an improved nozzle construction of the character indicated, which is composed of relatively few parts, adapted to be quickly and easily assembled.
A still further object is to provide an improved nozzle construction of the character indicated,
which is of relative simple construction, durable Figure' i is a view similar to Figure-3 showing the valve member in another position of adjust ment'.
Figure 5 is a fragmentary, side elevational view of a portion of the nozzle, showing in front elevation, the finger-operated control element for the'valve member.
Figure 6 is a transverse, sectional view through the nozzle, taken substantially as indicated at line 6ii of Figure 1.
The nozzle construction embodying the present invention and as illustrated in the drawing includes-a main body member Ii), having a reduced shank portion Ii, formed with a plurality of" stepped-shoulders I2 of conventional shape; for a snug telescopic fit into the end of a section of flexible hose, such as indicated in dotted lines at I4.
The body proper above the shank portion II, terminates in an enlargement I5, of general tubular form, the external surface-of which is substantially cylindrical, as'may be seen" in thedrawing. The body is provided with a liquid passageway I'I opening at the lower endof the shank portion I I, while its opposite end terminates'in' a reduced size discharge orifice I8, inside of the cylinder portion I5.
Said cylindrical portion I5 of thebo'dy is formed with a pair of longitudinallyextending, diamet rically opposite slots I9, in the bottoms of which" is seated a plate-form reciprocabla valve member 2|.
internal end surface of the body'portion, I5, immediately surrounding the discharge orifice I8,
as seen in Figures 3 and 4 of the drawing. The
opposite ends of the plate-valve member M terminate in downwardly extending lugs 23 and 24',
which are adapted to serve as'stops and alter nately abut respectively against the externalsurfaceof the cylindrical portion I5," ofrthe body; III for limiting thev reciprocable movement of" the.
valve member in opposite directions.
The valve member as hereinshownis provided with a pair of apertures-26...s a, d1apart inLthe: direction of reciprocable-movement ofthe valve member, and preferably are ffa size attleast':
equal to the discharge orifice:l&.
A coil spring.21iisseatedataoneerrdin a socket- 28 formed inthe external Lwallfof. I the: lower portionof: the cylindrical; portion I5 of the. body member as seenin Figure 3 ofith'e drawing, and
the opposite end of said spring is positioned in abutting engagement with the inner surface of the down-turned lug 23. Said spring thus serves The slots are so dimensioned as to per=- mit the valve member to seat directly upon the.
to maintain the valve member in the position of adjustment seen in Figure 3, with the lug 24 in abutting relation to the external surface of the body. The lug 23 preferably is of a size somewhat larger than the lug 24 and serves as a convenient finger engaging portion for actuating the valve member.
It will be apparent that when the valve member is to be moved from the position seen in Figure 3, pressure is exerted on the lug 23 until said lug abuts against the external surface of the cylindrical portion I5 of the body, as seen in Figure 4 of the drawing.
In the position of the valve member as seen in Figure 3 of the drawing, the two apertures 26 are so disposed that a portion of each aperture is aligned in overlapping relationship to the discharge orifice I8. In this position of adjustment, the liquid discharged through the orifice and the apertures is broken up and tends to assume the form of a spray, and when the valve is adjusted to the position seen in Figure 4 of the drawing, the liquid discharged through the orifice l8 and the registering aperture 26 tends to form a stream.
The valve member 2| is held in seated, operative position by a nozzle tip 30, which is of generally tubular form and dimensioned for a snug telescopic fit into the tubular body portion I5, with the end thereof abutting firmly against the upper surface of the valve member 2 I, as seen in the drawing. The external surface of the tip adjacent the lower end, is preferably provided with a pair of longitudinally extending ribs 32 dimensioned for a snug fit Within the slots I9 of the cylindrical portion I5. The dimension and shape of said ribs desirably conform to the contour of the body portion I5, as seen in the drawing. The bore of the outer end portion of the tip is formed slightly fiared in an outwardly direction, and as seen in Figure 3 of the drawing is of generally frusto-conical formation. It may be here mentioned that the characteristics of the bore at the discharge end of the tip 39, as
well as the size and relationship of the apertures 26 to the orifice I8 are the main determining characteristics as to the size and nature of the spray to be produced. Slight variations in either of these features" definitely affects the nature of the spray produced.
For simplicity in manufacture and assembly of the parts constituting my improved nozzle, I preferably form the body Ill and the tip 30 of suitable plastic material, and these two parts may be quickly and permanently assembled and united together, with the valve member 2| in proper relation, by merely coating the engaging surfaces of the respective parts II and 38 with some suitable solvent.
It is to be understood that in the assembly of the tip 30 to the body I I, the inner end of said tip abuts firmly against the valve plate 2I and thus tends to insure against leakage of the liquid, around the valve plate and prevents leakage through the joint or connection of the tip to the body. This constructional arrangement also has a further advantage in that it permits readily accommodating slight variations in thickness of the metal of the valve member 2 I To further insure freedom of reciprocable movement of the valve member, the transverse internal end surface of the body portion I5 is cored to form a recess 33, so as to leave a central annular area or embossment surrounding the orifice I8, the diameter of which is substantially the same as the width of the valve member 2|.
It will thus be apparent that by virtue of the construction herein disclosed that normally the valve remains in the position seen in Figure 3 of the drawing under influence of the spring 21, and the liquid that is discharged through the orifice I8, apertures 26 and tip 30, will assume the form of a spray, and when it is desired to convert the spray into a stream, it merely requires the exertion of slight pressure on the finfier piece 23, so as to shift the valve member to the position seen in Figure 4 of the drawing.
Although I have herein shown and described a preferred embodiment of my invention, manifestly it is capable of modification and rearrangement of parts Without departing from the spirit and scope thereof. For example, the size and relationship of apertures in the valve member may be varied in shape, number or size, so as to obtain a desirable form of spray. I do not therefore wish to be understood as limiting this invention to the precise form herein disclosed, except as I may be so limited by the appended claims.
I claim:
1. In a liquid discharge nozzle of the character described, the combination of a body of generally tubular form provided with a shank portion for connection to a hose, said hose being formed with a liquid passageway therein, terminating in a discharge orifice, a reciprocably movable valve plate mounted in said body in position for controlling said orifice, said plate being movable in a direction transversely of the axis of the body and being formed with a pair of apertures spaced apart in the direction of movement of the plate, and stop means for limiting movement of said plate in opposite directions, said stop means and valve plate being so dimensioned and correlated that at one limiting position of movement of the plate a portion of each aperture is disposed in overlapping registration with said orifice to produce a liquid spray, and at the other limiting position of movement of the plate one of said apertures is disposed in full registration with said orifice to produce a liquid stream.
2. In a liquid discharge nozzle of the character described, the combination of a body including a shank portion for connection to a hose, and having one end terminating in a tubular enlargement, provided with a pair of diametrically opposite slots, said body being formed with a liquid passageway terminating in a discharge orifice in said enlargement, an apertured reciprocably movable valve plate seated in said slots in position for controlling said orifice, said plate being movable in a direction transversely of the axis of the body, stop means for limiting movement of said plate in opposite directions, said stop means being so positioned that at one limiting position of movement, an aperture of the plate is disposed in registration with said orifice, and a tip of tubular form disposed in telescopic relation to said enlargement in abutting relation to the valve plate, and having a pair of external ribs snugly fitting said slots.
