EYS United States Patent Qlitice 2,722,453 Patented' Nov. 1i', i1955 2,722,453 OSCILLATING (SPRAY RIG PIPE Clifford Moore, La Verne, jCalif. Application September Y12, 1952', Serial No. 399,293' i 4 Claims. (ci. 299437) This invention relates to spraying devices, and more particularly, has reference to a' device of'the ycharacter referred to that can be mounted upon a trailer, and used with particular eiectiveness` 4in spraying citrus groves and the like, wherein the' object to be sprayed is of substantial size, and must besp'r'ayed fromtop to bottom thereof.
ln'large scale spraying operations of the character referred to,'it will be appreciated that itV is a ditlicult problem' in the art to provide 4for large scale spraying operations, that can be carried out in a minimum of time, and wherein'lthe large objects, suchasl citrus trees, will"still be uniformly and completely sprayed from top to bottom and from side to side thereof. Heretofore, spray rigs have beeny devised, for the purpose of carrying outthese operations, butto my knowledge, there has notv been conceived, so far, a spray rig adapted to be mounted upon a truck, trailer, or the like, which will be so designed as to direct sprays of insecticide' orthe like toward areas of the objects .being sprayed, in a manner to completely and uniformlyl'c'over said areas, and with the jets or sprays of liquidibeing'. shifted'through a predetermined spray pattern, by meansl 'of an automatically operating mechanism incapable of being 'affected by human error.
The main object of the present invention is toprovide a spray rig which will sol operate, and in' carrying out the invention, I provide a rig wherein an elongated, vertically disposed, bank or series of spray nozzles will be caused to" oscillate about a vertical axis, with lthe individual nozzles'that make up said series oscillating about horizontal axes radiating from said vertical,"main axis.
It is a furtherimportant object of the present invention to provide a rig of the character referredv to wherein a drive means embodied in the structure for the purpose of 'imparting the joint and individual oscillatory movement to the nozzles will be effectively linked with pumping means, to provide a continuous supply of liquid underpressure to' the nozzles.
Yet another object of the present invention is to provide, in a rig of the character referred to, means' for bodily tilting the entire rig about a horizontal axis, for the purpose of disposingsaid rig horizontally during movement thereof from place to place.
Still another object of importance is to provide, in a rig as stated, an arrangement wherein a plurality of different liquids can( be 'comingled ldire'ctly'within the rig, d'uring the spraying operation.
Yet another object of importance is to provide a spray rig as stated which will be ldesigned to spray largeobjects of the character stated in a minimum time, from top to bottom and fromy side to side thereof, while still being'conned in a relatively nai-row area, thus to permit travel of the rig between closely spaced rows lof trees.

Referring'to the drawings in detail, I have designated generally bythe reference numeral 10, a trailer, which can-be attachedf to a suitable traction vehicle, not shown. Alternatively, the spray rig constituting the preserit invention can be mounted directly 'p'o'n' a self-propelled vehicle, such as a truck or the like.
lnk any event, there is mounted upon the body of the trailer 10 a housing` designated generally .by the reference numeral 12,', said housing beingdivided into a plurality of compartments including, at the rear end cf the housing, a drive machinery casing" 14,` anda tank 16 extending from Athe intermediate portion of 'the' housing to the front en'd thereof.y An access door 2`ll`'is provided in the top` wall of the machinery/'casing' I4, to provide access to the' power means disposed` therein,v and also to permit filling of the tankthrough' fill pipe 22.
ln use of the invention, the tank-` 16 is filled: with insecticides comprising concentrates, liquids,` andpowders mixed with water in speciied proportions.
Welded or otherwise lixedly secured to the' rear end wall of the casingl4v is an" elongated, vertically disposed main support plate 28, said plate being disposed tra s"- versely of the structure and having its upp'ei` endp'rojecting above the top wall of the housing 1'2; Th'l'wer end of the main support plate' 28 projects below the bottom wall of the housing 12, and is`integrally"for'rned with a rearwardly directed, horizontally disposed bot'- tom support plate 3i). Integral with the upperetid of ,the main support plate 2S is an inclined support'plate 32, said top support' plate also being' extended i'fe'arwardly from the housing 12.
For the purpose of rigidifying'the construction of the plates 23, 30,32, there are provided reinforcing flanges 34, said anges extending continuously albiig theopposite sidesof the several plates.
Referring to Figures 3v and 5, there' is fixe'dly but separably connected to the bottom plate" 30"a' boom support plate 36, said boom support plate overlying the bottom plate 30, and extending substantially from one side edge to the other side edge of said'bottom plate', at the rear or free end of the bottom plate'.y
At its opposite ends, the boom support plate 36 is llixedly connected to the bottom plate 3) by means of bolts 37 or equivalent fasteners. At su'ch time as the boom support plate 36 is to be detached from the bot'- tom plate', the bolts 37 are removed.
Welded or otherwise xedly connected to the" top surface of the boom support plate 36, medially between the opposite side edges ofthe support structure de'ned by the plates 2S, 30', 32, is a bearing cup 38, containing anti-friction4 elements 40 (Figure 5). An" elongated, tubular b`o`oin` 4i12 has its lower end extended into taken slubthe bearing cup 38, said lower end of the boom being provided with a collar 44 engaged within the bearing cup, and overlying the anti-friction elements 40. Integral or otherwise made rigid with the collar 44, and depending therefrom, is an axial, reduced, threaded extension 46 of the boom 42, said extension extending downwardly through a center opening formed in the boom support plate and projecting into a recess 48 formed in the free or rear edge of the bottom plate 30. A nut S is threaded upon the extension 46, for the purpose of holding the boom 42 in a properly assembled relationship to the bearing cup 38 and antifriction elements 40.
Medially between the opposite ends of the boom 42, I provide a bearing 52 extending about the intermediate boom portion, the boom being journaled rotatably in said bearing and in the bearing cup 33. A bearing support plate 54 has one end circumposed about and engaged With the intermediate bearing 52 of the boom, the other end of said bearing support plate being hingedly connected, by means of a hinge pin 56, to the free end of the flanged, top support plate 32 of the main support structure.
As will be noted, the axis of hinged movement of the bearing support plate 54 is horizontal, and thus, when the bolts 37 are removed in a manner effective to detach the boom support plate 36 from the bottom plate` of the support structure, the boom and all the parts carried thereby can be tilted about a horizontal axis det fined by the hinge pin 56 to the dotted line position shown in Figure 1, in which position the boom is horizontally disposed and may be readily transported from place to place for spraying operations.
Means is embodied in the invention for automatically effecting rotatable movement of the boom 42 during the spraying operation, with said means being arranged to cause the rotation of the boom about its longitudinal axis first in one direction and then in an opposite direction, so that a plurality of spray nozzles carried by the boom will be given oscillative movement about the boom axis and will thereby cause spray jets to be directed from side to side of the objects being sprayed.
To this end, there is rigidly secured to the boom 42 a pair of radial arms S8 of plate-like formation, said arms being respectively made rigid with the boom at locations spaced longitudinally of the boom, and being disposed normally to the axis of rotatable movement of the boom. The arms 58 extend in the direction of the main support plate 28, as best shown in Figures l and 5, and in those ends of the arms disposed nearer the plate 28, I form aligned openings in which studs or trunnions 60 are loosely and rotatably engaged. The trunnions 60 extend in opposite directions from the opposite ends of an elongated guide block 62, said block being disposed in parallelism with the boom 42, and being formed with a longitudinal slot 64 closed at its opposite ends.
Mounted for sliding movement within the slot 64, between the opposite ends of said slot, is a slide 66, said slide being held assembled with its associated guide block by means of ears 68 secured to the opposite walls of said slide and extending laterally of the slot 64, said ears extending in opposite directions and being slidably engaged with opposite walls of the guide block 62.
The slide 66 is formed with a centrally disposed, transverse bore in which is rotatably mounted an eccentric pin 70 projecting outwardly from the marginal portion of a driven wheel 72 secured to one end of a horizontally disposed shaft 74 for rotation with said shaft, The shaft 74 is journaled, intermediate its ends, in a flanged bearing collar 76, mounted upon a bearing plate 78, that is rigidly secured at its opposite ends to the side anges of the main support plate 28, intermediate the opposite ends of said main support plate.
The other end of the shaft 74 is journaled in a bearing 80, mounted in the rear end wall of the casing 14 and in the main support plate 28.
For the purpose of driving the shaft 74, I secure, to the intermediate portion of the shaft, a drive sprocket 82 around which is passed a chain 84, said chain being extended about an idler sprocket 86 (Figure 3) carried by a shaft 88 journaled in a bearing 90 secured to one side flange of the main support plate 28. The shaft 88 of the idler sprocket 86 can be adjustably positioned, in a manner well known to those skilled in the art, for adjusting the tension of the chain 84.
The chain 84 is also passed about a drive sprocket 92 keyed or otherwise secured to a drive shaft 94 journaled in the main support plate 28, said drive shaft having intermediate its opposite ends a bevel gear 96 and being driven from an engine designated generally by the reference numeral 98 and mounted within the casing 14.
From the construction which has so far been described, it will be apparent that on operation of the engine, the wheel 72 will be rotated, and as a result, the slide 66 will be given up and down movement within the slot 64, the guide block 62 being reciprocated bodily in a horizontal path, thus to transmit rotatable movement to the vertically disposed boom 42, with the direction of rotation of the boom being continuously changed.
Means is also embodied in the invention for supplying liquid continuously to the hollow boom 42, during the spraying operation, and to this end, a pair of supply pipes 100 (Figure 4) are mounted within the casing 14, one end of each pipe communicating with the tank 16 and the other end of said pipe extending to a pump 102. ln the illustrated embodiment of the invention, a pair of pumps 102 is provided, said pumps being spaced transversely of and within the casing 14, but I believe that it is Well within the spirit of the invention to provide a single pump for the purpose of forcing a liquid under pressure to the hollow boom 42.
The pumps 102 are driven by pump drive shafts 104 disposed normally to and extending in opposite directions from the main drive shaft 94, the pump drive shafts 104 being provided with bevel gears 106 that are in mesh with main bevel gear 96 so that the bevel gear 96 constitutes a motion-transmitting member imparting rotation to the shafts 104 by meshing with the gears 106 to drive the pumps 102 from the drive shaft 94 driven by the motor 98.
The liquid pumped is directed into upstanding boom supply pipes 108, disposed exteriorly of the housing 12, and extending upwardly along the rear end wall of said housing. Manually operated valves can be utilized to close the flow of liquid through either or both of said boom supply pipes.
At their upper ends, the pipes 108 are in communication with supply hoses 112, said hoses being of a exible nature and extending into communication with the intermediate portion of the boom 42. Connecting fittings 114 are employed for the purpose of connecting the hoses 112 to the boom.
The boom 42 supports a series or bank of spray nozzles, the nozzles of said series being arranged in pairs, and said pairs being disposed in a line parallel to and spaced from the boom. To provide a support for the nozzles, the boom 42 has a plurality of laterally projecting spindles 116, said spindles being welded or otherwise xedly secured to the boom, at locations spaced longitudinally of the boom. The spindles 116 have rotatably mounted thereupon sleeves 118, said sleeves being rigid with nozzle support arms 120 disposed transversely of the sleeves, at the outer ends thereof. The nozzle support arms 120 have clamps at their opposite ends, each clamp engaging a nozzle 122. Thus, it is observed that each pair of nozzles is mounted rotatably upon the boom, for movement about an axis normal to the longitudinal axis of said boom.
To supply liquid under pressure to the spray nozzles 122, I provide exible connecting hoses 124, said hoses being connected at one end to thei respective nozzles of each pair of nozzles, and being connected at their other end, by means of Ls 125 to Ts 126, said Ts being secured to the boom 42 .(Figure`6).
I provide means for imparting oscillative movement to each pair of nozzles, about the axis defined by the spindle 116 associated with each of said pairs, during oscillative movement of the complete bank of nozzles about the axis of rotation of the boom 42. To this end, there is made rigid with each sleeve 118 a radial arm 128, said arms being pivotally connected, at their outer ends, to an elongated, reciprocating, connecting rod 130. The rod 130 extends for substantially the full length of and is in parallelism with the boom 42, and for the purpose of imparting reciprocating movement to said rod along a line parallel to the boom axis, the rod is provided, intermediate its ends, with a ball joint 132 (Figures l and whereby the rod is attached to a rodactuating link 134. The link 134 is inclined relative to the rod 130, as best shown in Figure 5, and at its lower end, is pivotally connected at 136 to an ear 138 rigid with a sleeve 140 disposed radially of the boom 42, and rotatably mounted upon a spindle 142, said spindle being made rigid at its inner end with the boom.
Integral or otherwise made rigid with the sleeve 140, and depending from the sleeve in parallelism with the boom axis, is a stub shaft 144, on the lower end of which is rotatably mounted a block 146 pivotally connected to a yoke 148, said yoke being rigid with a substantially horizontally disposed shaft member 150 coupled by a ball joint 152 to a swingable arm 154 mounted to swing about a vertical axis defined by an upstanding spindle 156 (Figure 7). The spindle 156 is connected to the arm 154, by extension of said spindle through a transverse bore formed in the arm 154, said bore communicating with a socket of the arm in which is provided a spring 158 exerting pressure against one side of the spindle, the other side of the spindle being engaged by a plug 160 threaded into said socket.
The spindle is fixedly connected to the outer end of a support arm 162, said arm being rigid with the boom support plate 36.
It is to be noted that when the spray rig is to be tilted to the horizontal position shown in dotted lines in Figure l, the slide 66 will be withdrawn from the eccentric pin 70, the pin 70 being tted loosely in the opening provided therefor in the slide. Additionally, when the spray rig is to be adjusted to said horizontal position thereof, the bolts 37 would be removed, and the boom and the several parts connected therewith will be tiltable bodily to the desired horizontal position.
I believe it is apparent, from the description which has been provided, that during operation of the spray rig, spray jets will be directed from top to bottom of the large objects, such as trees, that are being sprayed, and will at the same time be directed from side to side of said objects, thus to cause the entire object to be sprayed uniformly and completely, in a minimum amount of time. In this way, an entire line of trees in a grove can be quickly and effectively sprayed, in a short time, by a spray rig formed in accordance with the present invention and moving along said line.
The effective spraying action referred to is obtained, in the first instance, by oscillation of the vertically disposed series of spray nozzles as a unit, about a vertical axis, with said spraying action being further obtained by joint oscillation of the several pairs of spray nozzles about horizontal axes, the last named oscillative movement of the spray nozzles being provided for during the oscillative movement of the bank of nozzles about said vertical axis.
All this is achieved automatically, and the drive means used in bringing about the oscillating action is, at the same time, adapted to drive pumps whereby iiuidis supplied under pressure to the several pairs of spray nozzles.
It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles of operation and the means presently devised to carry out said principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claims.
