An object oi the present invention is to provide I a spray nozzle comprising a valve having a suitable operating handle. and means being provided in connection with said handle for holding the valve in open position. A further object is to provide a valve mechal0 nism for controlling iluid flow from a suitable conduit, and said valve mechanism comprising an operating handle having a trigger element associated therewith and adapted to automatically minne a position to hold the valve in open posill tion. when the handle -is operated to openfthe valve mechanism, said trigger element being so arranged that it may be conveniently moved into inoperative position by the operator's finger, when itisdesiredtoclosethevalve.

Other objects oi' the invention will appear from I0 the following description v`and accompanying drawing andwillbepointed outinthe annexed 'claims'.

Y* In the selectedrembodiment of the invention iluid under pressure. The body 2 is shownvprovided at its oppositeend with a threaded 'extension 5 adapted to receive a conventional spray head 6, indicated in dotted lines in'Figure 1.v
As best illustrated in Figure yl, the body 2 is 5 provided internally with a valve seat- 1, adapted to be engaged by a suitable valve 8, whereby iluid ow through the passage 9,.connecting the interior of the valve body with the spray head t,
may be controlled. The valve 8 is shown having li)` a stem Il,l the lower end of whicl is guidingly supported-in a cap i2, received in threadedk engagement with the body 2 of the'hozzle, as shown at ilin Figure l. A suitable packing il is preferably provided in the cap I 2, and is held in posi- 16 tion by the action of a spring i5. This spring also serves to constantly urge the valve 8 into emement with the seat 1.
'.lhe projectingendportion it ofthe valvestem .y Il is shown pivotally connected to an operating 20 handle Il, which intum, is plvoted to the body2, as shown at Il. The handle l1, being pivotally vconnected tothe valve stem il. is normally held in the position shown in Hgure 2 by the action of the spring I B f- An important feature of the present invention resides in the provision o! means for holding the valve in open position, without grasping the handle l1 and depressing it. As clearly illustrated in the'drawing, the means for thus holding the valve $0 in open position is shown comprising an element. generally indicated by the numeral Il. This element is pivotally connected to the pivot pin 2|. which connects the valve stem to the handle i1. The pivotal connections I I and 2| are suiliciently as looseto permit the lever i1 and valvestem il to .move freely without binding, when the lever is actuated.
The element il is preferably made of sheet metal. and comprises a U-shaped straddles orilts over a portion of the handle I1.. whereby the pivot pin 2i may be inserted through the alined apertures provided in the side walls 22 of the element Il, handle i1, and terminal il oi' thevalvestemll. f The wall-portions 22 of the pivotedelement il are eccentrically withrespect tothe axis' of the pivot pin 2|; whereby when the element is positioned as shown in Figure 1, the upper edges of its wall portions 22 will engage the adjacent 50 face or the cap i2 and thereby hold the valve 8 in open position, as clearly illustrated in Figure 1. The element I! has a linger `portion 28, simulating somewhat a trigger. It is adapted to be engaged by the forenger of the operator-s Il bodywmcn of hand, whereby it may be conveniently moved from the position shown -in Figure 1, to that shown in Figure 2, or, in other words. from operative to inoperative position. A spring 2l is shown having one endv connected to a smallarm or extension 25 of the element I9, and its opposite end is suitably secured to the handle I1, as shown at 26 in Figure 1. The spring 2l constantly urges the element i! into operative position, as shown in Figure 1, thereby to hold the valve in open position. When the element i9 is swung into the position shown in Figure 2, the valve may move into engagement with the seat 1 to prevent or control iluid iiow through the body 2.
In the operation of the apparatus, the operator may grasp the pipe I, one end of which is usually connected to a flexible hose having a connection with a source of liquid under pressure. 'I'he handle I1 is conveniently located adjacent to the pipe l so that the operator may, if he so desires, grasp both the pipe I and handle I1 with one hand, during the spraying operation. When the handle I1 is moved to valve opening position, as shown in Figure 1, the pivoted element I9 comes into play, and unless the operator holds` it in the position shown in Figure 2, automatically assumes the position shown in Figure l, thereby holding the valve in open position so that the operator may release his grip upon the handle I1. The spray nozzle and head may then be moved about in any convenient manner without requiring any attention on the part of the operator. This enables the operator to hold thespray nozzle in any desired position, when spraying shrubbery, trees, and other plants, and greatly facilitates the operation of spraying in that the spray nozzle or'head may be conveniently held in an invertedl positionunder the leaves of the plants without twisting or bending thewrists and arms, as is often necessary, when the valve` handle I1 must be manually heldin open position. y I y When the valve is to be closed, the operator 'simply moves his vforeilnger into engagement with the trigger 23 and pulls it downwardlyfrom the ,position shown in Figure 1 to that shown in Figure 2, whereupon the -spring I5 will cause the handle I1. to move into valve closing position, as shown in Figure 2.
' From `the foregoing, it will be noted that the pivoted trigger element provides a very simple and practical device for holding the valve in open position. In ordinary use, particularly when the operator nds it necessary to constantly alternately open and close the valve 8, the operator may. keepv his forenger on the trigger 22 and holdvit in the position shown in Figure 2, whereby it is ineffective to hold the valve open. When, however, the operator iinds it desirable to'lock the valve in open position, he simply releases the trigger 23 and opens the valve by` inwardly pressing the handle I1 rtoward the pipe 4, whereupon the spring 24 will automatically swing the trigger element I9` into operative position, as shownin Figure 1,' in whichposition it will be held by the spring 2l until the operator again swings it into inoperative position by depressing the trigger 22,
'Ihe invention herein disclosed, has proven very practical and efiicient in operation and presente the utmost in simplicity. Its construction is such that it may readily be attached to spray nozzles of the general character illustrated in the drawing, substantially without requiring any alterations in the construction thereof. It is to be noted that the element Il is supported entirely by the pivot pin 2|, which connects the upper end of the handle l1 to the valve stem It, whereby it may readily be detached from the spray head, when desired.
In Figure 3, there is `shown a structure o! slightly diilerent construction, in which a manually operable element, generally indicated by the numeral 21, is utilized for holding the valve l in open position. In the form here shown, the
- element 21 comprises a body portion 28 of boxlike formation, which is pivoted to the stem I6 and handle I1, in a manner similar to the form shown in Figures 1 and 2. 'I'he body portion 2l is provided with suitable finger-engaging portions 29 which are so disposed that they may be conveniently manipulated by the operators nger to move the element 21 from one position to the other,-as indicated by the full and dotted lines in Figure 3. The finger-engaging portion 29 of the element 21 may be otherwise formed, as will readily be understood, provided it is so arranged that it may be conveniently engaged by the operators finger to move the element into or out of valve-opening position.
