UNIVERSAL DIRECTING DEVICE FOR SPRAY NOZZLES .Filed April 15, 1955 13'!" ilm:
Jab/1 L. Palmer BMFM,
United States, Patent O '"ce UNIVERSAL DIRECTING DEVICE FOR SPRAY NOZZLES John E. Palmer, Calgary, Alberta, Canada Application April 15,1955, Serial No: 501,610 I 1 Claim. (Cl. 299-73) My invention relates to new and useful improvements in universal directing devices for spray nozzles the principal object and essence of my invention being to provide a devieepormally attachable'tora tractor which is completely universal in its application inasmuch as it includes means to raise and lower the nozzle, to movethe supporting tube of the nozzle in the verticaland horizontal plane and means to move the supporting tube aroundlthevlongitudinal axis thereof.
A further object of my invention is to provide a device of the character herewithin described which enables the.operator .to direct. the spray from the nozzle in-l'anyldirection readily .and easily, :thereby enabling him to reach remote locations and to allow for prevailing wind.
Yet another object of my invention is to provide a device of the character herewithin described which is easily attached to a conventional tractor or the like.
Still another object of my invention is to provide a device of the character herewithi'n described which is simple in construction, economical in manufacture and otherwise well suited to the purpose for which it is designed.
With the foregoing objects in view, and such other objects and advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:
Figure 1 is a side elevation of my device.
Figure 2 is a top plan view thereof.
Figure 3 is an enlarged end elevation of the nozzle of my device. I
Figure 4 is an enlarged view showing the connection between the supporting tube and the supporting standard.
Figure 5 is a side elevation showing an alternative embodiment of my device.
In the drawings like characters of reference indicate cor-responding parts in the different figures.
Proceeding now to describe my invention in detail, it will be seen that I have illustrated the device as mounted upon a tractor floor plate 1 by means of a tubular standard 2 and braced to the tender 3 of the tractor by means of a strut 4.
A stem 5 is adapted to slide within the tubular supporting standard 2 and to form part thereof, a clamp 6 being provided adjacent the upper end of the tube which may, if desired, clamp the stem firmly in position. A movable collar 7 surrounds the stem and limits the downward movement of the stem within the tube, thus enabling the stem to be raised or lowered with relation to the tube as desired. With the clamp in the loosened position, the stem may be rotated within the tube, thus enabling the device to be rotated in a horizontal plane.
A substantially horizontal supporting tube 8 is 2,857,201 Patented Oct. 21,1958
mounted to the upper end of the stem portion 5 of the supporting standard by means hereinafter to be described, saidsupporting'tube 8 being hollow and having means 9 at one end thereof, to which may be connected 2. fluid conduit 10 communicating with the interior of the tube 8. The opposite end 11 of the supporting tube 8-is provided with a conventional spray nozzle 12 secured thereto by means of pivot- 13, itbeing understood that the spray-nozzle 12 also communicates with the interior of the supporting tube 8. Means to pivot the nozzle 12 within limits through an are indicated by the reference character 14, take the form of a crank arm 15 secured to the nozzle and'extending upwardly therefrom.
Ahand lever 16 is pivotally secured to the end of the tube S' adjacent the conduit 10 and a link rod 17 extends between the hand lever 16 and the crank arm 15, being guided through sheave 18. From the foregoing, movement ofthe-hand lever 16 through the are 19 causes the aforesaid pivotalmovement of the nozzle 12 through the are 14.
3 The tube 8 is rotatably mounted within a sleeve 20, which in turn is welded to a clamp 21, said sleeve form ing a bearing forthe supporting tube 8 and permitting same to be rotated around the longitudinal axis thereof also by means of the hand lever 16, as well as permitting movement of the tube 8 longitudinally within the sleeve 20.
The clamp 20 forms part of a spring loaded split ring assembly collectively designated 22, which permits the supporting tube to be pivoted vertically between the limits indicated, for example, by the broken lines 23 and 23'. This split ring assembly comprises a stationary ring 24 secured to the top of the stem 5 and having an inner serrated space 25. The clamp in turn forms part of a movable split ring 26 also provided with an inner serrated space 27, these two serrated spaces being in interfacial relationship. A spring loaded nut and bolt assembly 28 extends through the rings and maintains the serration in engagement, but permits the ring 26 to be moved with relation to the ring 24, thus permitting the vertical movement of the tube aforesaid.
From the foregoing it will be appreciated that the nozzle 12 is completely universal in direction, being capable of pivotal movement with relation to the tube 8, being capable of upwardly or downwardly movement due to the split ring clamp assembly 22, being rotatable in a horizontal plane due to the stem 5 being rotatable within the tube 2, and being rotated around the longitudinal axis of the supporting tube 8 by virtue of the engagement thereof within the sleeve 20.
Also illustrated in Figure 1 is an hydraulic cylinder and piston assembly 29 extending between the stemv 5 and the tube 8, which may be connected to the hydraulic unit of the tractor if desired, to enable hydraulic control of the vertical pivotal movement of the tube 8.
Proceeding now to describe the embodiment illustrated in Figure 5, this embodiment is specifically designed for use when spraying cattle, and is adapted to be held in the hands of the operator. It also comprises a main supporting tube 30 and a spray nozzle 31 pivotally secured upon the end 32 thereof in a manner similar to that illustrated in Figure 3 and described previously. A crank arm 34 extends upwardly from the nozzle corresponding to the crank arm 15, and this crank arm is adapted to move the nozzle between limits through the are 35.
The opposite end 36 of the supporting tube is provided with a hollow curved .handgrip 37 communicating with the interior of the tube 30, the distal end 38 of the handgrip having a fluid conduit 39 secured thereto. A trigger 40 is pivoted to the end 36 of the tube by pin 41 and is spring. loaded outwardly by means of spring 42. This trigger controls a fluid control valve (not illustrated) contained within the end 36 of the tube, and is adapted to control the flow of fluid therethrough.
The nozzle 31 is angulate'd by meansof a sleeve 43 surrounding tube 30 and -slidable' therealong, handgrip 44 depending from; the-sleeve for this purpose. 'A lug 45 extends upwardly from the sleeve and is connected tothe crank 34 by'means 'of-rigid-vlink 46, so that movement of thesleeve irrthe'direction of the double-headed arrow 47 causes .the'nozzle-tomove through are 48. This particular device is-suitable for spraying cattle whereupon the sprayingpfluid can readilybe directed upon the underside of the animal, one hand-holding the pistol grip 37 and'the other'thehandgrip '44.
Since various modifications can be made in my invention as hereinabove described,-andmany apparently widely dififerent embodiments of same made within the spirit and scope of the claim without departing" from such spirit and scope, it is intended that'allmatter contained in the accompanying specification shall beinterpreted as illustrative only andinotin a limiting sense.
What I claim as my invention is:
A universal directing device for sprayvnozzles comprising in combination a supporting standard',, a main supporting tube secured to said supporting standard, a spray nozzle pivotally securcdvto one end of said supporting tube and communicating. with the interior thereof,'and means to connect a fluid conduit to the other end limits upon said supporting tube, said means including a crank, arm secured to said nozzle, a handllever pivotally connected to said supporting tube, and link means extending between said crank arm and said hand lever, means to pivot said supporting tube between limits in a vertical plane, said means including a clamp on the upper end of said supporting standard, said supporting tube being held by said clamp, said clamp incorporating a spring loaded split ring assembly, said split ring assemblyincluding a stationary serrated ring on said supporting standard, and a'movable serrated ring on said clamp, said-'serrated' rings beingv "in interfacial relationship, and means to maintain said rings in said relationship, s'aidmeans taking the form of a spring-loaded bolt and nut assembly through said rings.
