Spray C
I HORACE FALK NEUMEYER, residing at Macungie, in the County of Lehigh
and State of Pennsylvania, Manufacturer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to spray nozzles; and it has for its object to provide a
nozzle of that character especially adapted for use in spraying fruit-trees, shrubbery,
plants, etc.
To this end the main and primary object of the present invention is to construct
an improved spray nozzle having simple and efficient means whereby the size of
the spray can be easily and quickly regulated, while at the same time means are
provided for delivering a solid stream, as the character of the work may demand.
With these and other objects in view which will readily appear as the nature of
the invention is better understood, the same consists in the novel construction,
combination and arrangement of parts hereinafter more fully described, illustrated
and claimed.
In the drawings:
Figure 1 is a perspective view of a spray nozzle constructed in accordance with
this invention.
Figure 2 is a central longitudinal sectional view thereof.
Figure 3 is a perspective view of the nozzle with the outer nozzle tube removed.
Figure 4 is a detail in perspective of one end of the nozzle spout.
Referring to the accompanying drawings:-A represents the body of the nozzle
having a threaded socket B at one end adapted to be coupled onto the hose leading
from a pump or hydrant, and beyond the threaded attaching socket B, at one end,
the body of the nozzle is extended into a reduced nozzle spout C, the orifice of
which is tapered at its inner end at c, while the extreme outer end of the spout of
the nozzle is cut at an angle to form an inclined valve seat D, onto which is adapted
to work the self adjusting valve plate E. The self adjusting valve plate E, is of
an oval shape and somewhat wider than the outer end of the spout of the nozzle,
so as to completely cover the spray orifice or opening at such outer end of the
spout, and said oval-shaped valve plate is provided at its inner end with the short
pivot studs F, mounted in the projecting extremities of the U-shaped bearing
plate G, fitted onto and extending around the nozzle spout C, near its outer
inclined end.
The
The self-adjusting valve plate E, which works onto the inclined valve seat D, at
the outer end of the nozzle spout, is normally held closed by means of the leaf
spring H. The leaf spring H, is made fast at one end as at I, to the body of the
Dozzle adjacent to the threaded attaching socket thereof, and at its other free end is
provided with an inturned tongue extremity J, engaging on top of the oval-shaped.
valve plate at a central point, to normally hold the same closed onto its seat.
said valve closing spring H, is provided at a point. intermediate of its ends with a
threaded opening K, to receive the adjusting screw L, working through said
opening and impinging on the spout of the nozzle whereby the turning of the said
screw in either direction will adjust the spring H, up or down, and this adjusting
screw is provided with a milled head M, which is easily grasped by the fingers in
adjusting such screw. The adjusting screw L, is also adapted to work through
an opening N, in the outer removable nozzle tube O. The outer tube O, is of a

page_text: length and diameter slightly greater than the main tube or spout of the nozzle, and is
adapted to have the inner end thereof detachably screwed onto the enlarged base
portion P, of the nozzle spout C, in front of the threaded attaching socket B. The
outer tube O, serves as a shield or covering for the working parts of the nozzle,
and in opposite sides at the outer end thereof is also provided with the oblique spray
slots Q, which agree with the angle of the inclined valve seat D, at the outer end
of the nozzle spout, and are sufficiently wide to freely accommodate the spray which
is deflected from the self adjusting valve plate and which issues laterally as well as
forwardly from between said valve plate and the outer end of the nozzle or spray
spout C.
In operation, when the adjusting screw L, is relieved from the body of the
nozzle, the valve spring H, is free to exert the entire tension thereof on the valve
plate, so as to hold it firmly closed over the outer inclined end of the nozzle tube C,
and in this adjustment the valve plate will not open unless the pressure of the
liquid being sprayed is sufficient, and if this is the case a very thin spray must
necessarily issue from the nozzle. By turning the adjusting screw to impinge
on the nozzle tube C, the spring H, will be lifted and thereby
relieved from the valve plate, which will open sufficiently to allow the water to be
formed into a spray by striking this plate and in issuing through the opening formed
between the same and the inclined valve seat D. By adjusting the screw L, still
further, the density of the spray may be increased, and the spring H, may even be
lifted away from the valve plate sufficiently far to permit the same to freely adjust
itself to the water and thereby allow a solid stream to be jetted from the nozzle.
the same
With the spring H, set for any desired density of spray it will be apparent that
in case any sediment should find its way into the nozzle, the pressure will naturally
increase sufficiently to overcome the tension of the spring to allow the obstruction
to pass out of the nozzle, after which the valve plate, under the tension of the
spring, will resume its normal position, and it will also be apparent that by varying
the pressure of the liquid forced through the nozzle a greater or less density of
spray may be formed, inasmuch as the valve plate is self-adjusting.
The many adaptations and advantages of the herein-described spray nozzle will
be apparent to those skilled in the art, and I will have it understood that changes
in the form, proportion and the minor details of construction may be resorted to
without departing from the principle or sacrificing any of the advantages of this
invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In a spray nozzle, the nozzle spout having an inclined outer discharge end, a
self-adjusting valve plate pivotally mounted on said inclined end of the spout, an
adjustable spring secured to the spout and bearing on said valve plate, and an outer
nozzle tube fitted over said spout, substantially as set forth.
2. In a spray nozzle, the reduced nozzle spout having an inclined outer discharge
end, a spring closed self-adjusting valve plate arranged to work over the inclined
outer end of the spout, and an outer nozzle tube arranged over said nozzle spout
and having oblique slots at its outer end agreeing with the angle of inclination of
the outer spout end, substantially as set forth.
3. In a spray nozzle, the body having a reduced spout provided with an inclined
outer discharge end, a plate arranged to work over said inclined end of the spout
to receive the pressure of liquid thereagainst, and an outer nozzle tube removably
fitted onto the nozzle body over said spout and having oblique spray slots at its
outer end agreeing with the angle of the outer discharge end of the nozzle spout,
substantially as set forth.
4. In a spray nozzle, the body having a reduced spout provided with an inclined
outer discharge end, an oval-shaped self-adjusting valve plate pivotally mounted on
the spout and adapted to work over the outer inclined end thereof, a spring made

page_text: fast at one end to said spout and having its other free end engaging on top of said
valve plate, said spring having a threaded opening, and an adjusting screw working
through the threaded opening of said spring and impinging against the nozzle
spout, substantially as set forth.
5. In a spray nozzle, the combination of the spout having an inclined valve seat
at its outer end, a self-adjusting valve plate pivotally mounted and working onto
said valve seat, a leaf spring arranged to bear at one end on said valve plate and
having a threaded opening, a set screw engaging the threaded opening of said spring
to adjust the same, and an outer nozzle tube detachably fitted onto said spout and
having oblique spray slots at its outer end disposed at the same angle as said
inclined valve seat, substantially as set forth.
