This invention relates lto spray-nozzles .and their attachment to ;spray booms. and theobject .of the invention-is "to; provide-an efficient .nozzle for use in agricultural sprayingj operations for crops, preferably asadaptable totransversely outspreading boom pipe" members .asfound in conventional; sprayinggapparatus.
The principal objection. to conventional means .of attaching the-nozzleszis that they are. screwed into threaded holes along :each boom pipe, the threads of which may so easily *becomestripped or worn. The advantage. in my invention is that these nozzles. herein described :arenot threaded for screwable -attachmer 1tin,tov the communication hole-intheboom-pipe, .and consequently damage from breaking when inadvertently hitting the ground orrrocks; and bending when roughly handled is easily remedied. The shortened neck ,of thenozzleis also'asafeguard against damage as compared with.;conventional types of nozzles.
With this invented nozzle'repairs and replacements are readily effectedbn the.site;-by-:merely .clamping and bolting a new nozzl'ifnecessary to the boom pipe without having to dismantle the parts or replace the boom pipeientirely, or even having to:ship the boom away for repairs. and consequently losing valuable time.
This invention-discloses awerysimple type of nozzle and without threads for engagement with the boom pipej and it includesv a"--screen'1.through which the spraying liquid must pass prior to'its emission through:the'i-sprayingmozzle aperture. This screen with its mounting stem may be readily removed fromthe .nozzle forpcleaning, and may be replaced by screwably manipulating the threaded portion ofthe stem into the nozzle head if and when necessary. .In my--.invented nozzle there is no boss-necessary on the boom pipe to screwably retain the nozzle, as'thereis found in .most conventional.- .types or spray machines, the retention of these parts being in my invention a matter of simply clamping two parts together.
The spray orifice in this nozzle is very small, as regards the orifice itself, and the screen is of very fine mesh material to prevent choking the orifice, and the screen is kept in spaced relationship with the stem in the interior of the boom pipe by threads cut on the exterior face of the passageway inthe stem communicates directly with the nozzle spray orifice.
Inrthis multiple-spray device the nozzles are spaced at equal intervals along each boom pipe, and the nozzle orifices are preferably ofsuch shape that theliquid is ejected therefrom in a fan shaped spray, although varying spray shapes and effects may readily beprovided.
This is a low volume spray system nozzle, and it isessential that the boom pipes and apparatus are continually travelling when in operation, as efiective spraying is dependent on a uniform coverage of the chemical-over the ground. This uniformity of coverage is attained by assuring that the axis of the orifice slot in the nozzle head .is longitudinally in parallel alignment with the .axis of the boom pipe, and is thus set perma nently. ,in 7 its relationship with the clamping parts.
The-ejected fluid from the orifice of the longitudinal slot .and holed ty-peis spread downwardly in a fan shape, and nozzles are so spaced apart as to. provide adequate coverage and yet assure that thereis no overlapping of the fluid as it spreads from one nozzle and from the next adjacent nozzle. Any spaces left between .spray streams or overlapping would tend todestroy the efiectiveness of the chemical fluid, with possibility of'destroying the twice sprayed area of the crop.
With' these objects and advantages mentioned this invention consists in the novel features hereinafter described and claimed, and illustrated in the drawings accompanying this specification.

Fig. 2 is an end view of the nozzle with hinged cap shown in open position, and with boom pipe in section.
screen stem.
Fig. 5 is a detail of stem holder and nozzle tip.
Fig. 6 is a side view of Fig. 5.
In the drawings the numeral I refers to a portion of a boom pipe as conventionally used in connection with farm spraying equipment, to which are attached spray nozzles as represented by 2 and in this invention there is a spray nozzle stem member 3 covered with a fine screen 4 for fitment inside the said boom pipe as part of the nozzle. There is a plurality of such nozzles along each boom pipe of the spraying apparatus.
In describing this nozzle there is a nozzle head or stem holder 5 retained in a clamp member with a base portion 6 and a swingable clamping cap I together forming a pipe clamp, and having a screw bolt 8 drawing clamping lugs 9 together for tightening the device around the boom pipe. The stem holder 5 fits into the base 6 of the nozzle in an aperture therein and the spray tip I is a downward extension of an integral with this holder member. The tip is formed by parallel flattened faces ll so flattened on the holder as to fit into the similarly shaped aperture l2 in the bottom of the base member 6, in order to secure the tip permanently aligned with regard to the axis of the boom pipe.
A hole running through the extension tip member, as seen at [3, extends up into the holder for the passage of the spraying liquid from a hollowed passageway l4 longitudinally extending within the stem 3. A slot I5 is passaged transversely across the bottom face of the tip member [0 which is set longitudinally parallel with the axis of the boom pipe, and being milled out with a circular tool this slot forms an elliptically shaped aperture within the spray hole # 3 on account of the arcuate shape so formed. Thus the spray is fan shaped in this particular case. Other shaped spray apertures may be used by merely inserting a diiferent type of tip member and its uniformly shaped holder.
The stem 3 is exteriorly threaded for most of its length to provide a space between the screen covering and the stem surface, and it is screwably threaded into the top of the holder 5. A slot i6 is passaged transversely through the body of the stem to communicate with the said vertical passageway [4 of the stem. It is through these passageways that the spraying liquid passes from the boom to the spraying aperture l3, for ejection therefrom, through the end orifice l3a.
The fine cylindrical screen 4 fits closely over that portion of the stem within the boom pipe between a head IT on the stem and a sealing gasket l8 inserted between the boom pipe and the holder 5. This gasket is compressed therefore when the screw bolt 8 is tightened to draw the lugs 9 together.
The stem 3 is inserted through a hole I9 in the underside of the boom pipe I, with the clamping cap 1 open, and the clamp closed and screwed down. These clamps actually reinforce the boom pipes.
With the type of screen used with my nozzle there is no possibility of sediment becoming trapped as in older flat screen types. This vertical cylindrical screen insures against screen plugging, and is easily replaced by merely unclamping the unit.
What I claim and desire to secure by Letters Patent is:
1. A spray nozzle device as described for clamping to a spray boom pipe without being screwed thereto, comprising a hollowed stem closed and 4 headed at one end, and open at the opposite end, and insertable into the boom pipe through an aperture in the bottom wall thereof, and having a passageway communication between the inerior of the stem and the inside of the boom pipe, a base portion as part of the nozzle device, an apertured stem holder insertable into said, base portion into which said stem is screwed and having a tip portion apertured for spraying liquid, a removable filter screen enclosing said stem, and a gasket between said holder and the boom pipe to render the device leak proof when clamped around said boom pipe.
2. In a spraynozzle device of the clamped on type for chemical spraying, a boom pipe for supplying the spray nozzles placed at equal intervals along said pipe, an exteriorly threaded hollowed stem for insertion through apertures into said pipe, a closure cap at the top of said stem, a screen enclosing said stem and distanced therefrom by its threads, a base portion as part of the nozzle device, an internally threaded stem holder within said base portion and apertured for its full depth, a portion of which aperture is to screwably receive said stem, a gasket to prevent leakage between clamped nozzle device and the boom pipe, a flat sided spray tip extending from said holder and apertured to communicate with the aperture in said holder to conduct the spray liquid from the boom. pipe, to fit into a correspondingly flat sided bottom aperture in said base portion for the alignment of the sprays.
3. A spray nozzle comprising a pipe clamp with a base portion, a swingable cap hinged to said base portion, lugs on each said portion of the clamp for bolting together, a screen-covered hollowed stem for insertion into a spray boom pipe of a spray machine, an apertured stem holder threaded for the reception of said stem, communication passageways through said stem to conduct spray liquid from the boom pipe through the stem and its holder, an apertured spray tip integral with said holder, a slot in said tip in open communication with the spray aperture therein, and means to seal the pipe clamp against leakage.
