Abstract
ABSTRACT OF THE DISCLOSURE
As the applicator is propelled about the surface to be treated, hollow spikes called tines or tongs are alternately thrust, vertically downwards below the surface and withdrawn vertically upwards. A bulk supply of treating liquid is maintained separate from the applicator, so the applicator is more maneuverable and less bulky. The supply is pressurized and supplied to the applicator via a high pressure hose line. The drive for reciprocating the tongs also powers a flow-dividing valve, which supplies the treating liquid to each of the tongs in turn, so that each tong liquid injects only when that tong is under the ground surface.

TIIF, Ol~IGI;~ALL.Y PRF:FI~RRl~D EMBOI)IMENT
_ _ _ _ The pre~surized liquid injector 10 includcs an a~plicator unit 12 connectcd by a high pressure hose linc 14 to a pressurized treating liquid supply 16.
In the instance depicted, the supply 16 takes the form of a tank wagon or the like 18 having a com-pressor 20 for placing the treating l~iquid under e.g.
150-600 p.s.i. The supply 16 may be e.g. from an agricultural orchard spraying unit, with the hose line 14 connecting to the applicator unit 12 rather than to a tree spraying wand.
The applicator unit 12 includes a frame 22 having right and left rear wheels 24 and a steering system comprising a two wheeled bogie or truck 26 journalled with respect to the frame 22 at 28 and having a forwardly projecting steering bar or tiller 30. A
gasoline engine 32 is shown mounted on the frame and equipped for driving the wheels 24.
The frame further includes an inverted yoke 34 which at 36 mounts a crank shaft 38 having~ e.g, six angularly disparate, axially spaced offset cranking portions 40.
(Conventional drive interruption~ clutch means are provided ~or disengaging the engine 32 from either the wheels 24 or the crank shaft 38).
, ,, ::
~a~3~s Each cranking portion 40 has a crank arm 42 journalled thereon which terminates in a clevis 44 which is in turn pivotally pinned at 46 to the upper end of a push rod 48 slidably mounted in a sleeve bearing 50 fixed on the rame 22.
Each push rod 48 has a dual tong injector unit 52 mounted thereon below the respective sleeve bearing 50.
In the instance depicted (see especially -Y 10 Figures 3 an~ 4) each dual tong injector unit 52 includes a body 54 which may be cast, although an -example fabricated by welding from plate and tube : :
is illustrated. The body 54 comprises a base plate 56 having a lateral projection 58 split at 60 leading to a vertical opening 62. A threaded lateral o ening 64 crosses the split 60 and receives a cap screw 66 for narrowing the split 60 to construct the opening :
62 for securing the body 54 on the respective push ,~
rod 48. Two laterally spaced vertical openings 68 ~:
receive the upper ends of two respective tubular injec-tor tongs 70. The latter are sealed with respect to the respective openings 68 by sealing ring means 72 and secured in place by nuts 74. ~;
Within the body 54, passageways 75 communicate the two tongs with a valve housing 76 incorporated ~:
into the body 54. :~
As depicted, the valve housing 76 is an up-right, composite tubular member 78 having its through-bore 80 in communication with the passageway 75 at ::
the lower end of the throughbore 80.
,i~.,~
, ' .,,, . .:
:, . - , . . . , : ~
3~
The lower most portion 82 of the housing ~;
76 is internally threaded at 84 to receive the ex-teriorly threaded lower end of an intermediate tubular portion 86. An internal seal is made between these two parts at 88 and an external seal is made between them at 90. Intermediate these seals 88, 90, the parts 82 and 86 are radially spaced from one another circumferentially to define an annular chamber 92 the throughbore 80 flares upwardly to provide a frusto~
conical valve seat 94. Above the valve seat 94 radial bores interconnect the throughbore 80 with the chamber 92. A conduit 98 connects the chamber 92 with a hose fitting 100.
The valve housing intermediate portion .
upwardly terminates in an internally threaded portion 102 which receives the externally threaded lower end .. .
104 of an upper portion 106. A seal is formed be-tween these parts at 108.
A valve body 110 is reciprocatingly received in the throughbore 80 above the valve seat 94. It includes a conical tip 112 preferably made of re-silient material such as nylon for sealing against the valve seat 94 when the valve is closed. The body 110 has a metal rod 114 as a stem. This rod 114 ; :~;
projects up the throughbore 80 and out the upper end thereof through an annular gland nut 116 which seals with the rod at 118. ~ :~
A compression coil spring 120 encircling the rod 114 within the bore 80 gains purchase between the ;~

~.,. ~ .
-11 - ~, :: , . . . . .
enlarged head 122 of the valve body and the lower end of the valve housing upper portion 10~ to nor-mally bias the valve toward a closed condition.
Outside the housing, a valve stem pusher 124 is mounted on the stem 114 with securement means 126. Accordingly, upward force on the pusher 124 raises the valve body away from the valve seat against the restoration force of the spring 120 permitting liquid supp~ied under pressure via the hose fitting 100 to : 10 flow through the conduit 98, into the chamber 92, through the radial bores 96, into the throughbore 80, down between the valve body tip 112 and seat 94, into ; the passageways 75, into the two tongs through radial passageways 128, down the throughbores 130 of the two respective tGngs and out the radia~ing openings 132 provided just above the solid, pointed lower tips 134 of the two respective tongs.
Each dual tong injector unit body 54 further - includes a tubular, generally vertical, valve actuator mounting sleeve 136 disposed adjacent the valve housing.
The sleeve 136 acts as a sleeve bearing for an actuator ; .
rod 138 which has a lower end 140 protruding below the lower end of the sleeve 136 for engagement with the ~ ~
surface of the ground. The re~ion 144 near the upper ~ -` 25 end of the rod 138 is externally threaded and protrudes above the upper end 146 of the sleeve 136 and threadably mounts an internally threaded flange member 148. The latter has a flange portion 150 which protrudes laterally 4i~349 into the external lateral groove 152 of the valve stem pusher 12~, connecting the valve stem to the actuator so that when the actuator is pushed up by contact of the lower end 142 with the ground, the valve is opened until ~urther rotation of the crank -:
shaft 38 raises the dual tong injector unit under consideration sufficiently to permit the actuator rod 138 to begin to lower. It should be apparent ~hat rotative adjustment of the flange member 148 rela~ive to the rod 138, by threading, vertically adjusts the deposition of the lower end of the rod ;.
138 with respect to the rest of the particular dual tong injector unit and the surface of the ground, thus ~ .
providing a means for increasing and decreasing the : :~
proportion of the vertical indexing cycle for the ;~
respective dual tong injector unit during which the i~
associated valve is open and the two associated ~-~ll tongs injecting. The earlier and later a valve is open the more liquid will be injected and the thicker the band of injection will be reaching the same depth ;-~
but extending up closer to the surface of the ground) - ~;`
other factors being equal. ~ ::
When being used, for instance ~o treat the turf of a golf course green, the tank wagon 18 is drawn i;
to its border and its contained treating liquid delivered ' under high pressure by the pump 20 through the hose line 14 to the application unit 12. That unit is led over the surface of green, much like a power mower. As the .~ . .
, , ~, .
'. ' ?~i f.,~
:~3~9 dual tong units 52 are indexed up and down by the crank shaft 38, the respective actua~or rods 138 strike the ground during the downstrokes opelling the respective valvcs 110 while the respective injector tips are below s the upper surface of the turf.
Each hose fitting 100 connects a flexible hose 160 with a manifold 162 mounted on the frame 22. The manifold 162 has an inlet pipe 164 which connects at its upper end with the high pressure hose 14 to receive a supply of treating liquid from the compressor 20 on the tank wagon 18. ~
Being able to treat with injections at relatively high pressure, while separating t~e bulX :
supply and pressurization bulk and weight to a relatively stationary place (the tank wagon) so that it does not ; have to be lugged around with the applicator unit makes the latter much more mobile and versatile.
There are instances where it is disadvantageous to operate the valves 110 from push rod engagement with the ground at 140. In such instances, suitable camming means may be provided which work from the cam shat 38 to cause the actuators 124 to relatively lift with res-pect to the valve housing 76 when the respective bodies 56 are moved downward because of ~heir securement on the respective vertically réciprocated rods 48.
In fact, as described bclow, an embodiment of - the latter sort, which eliminates the ne~d for a ~834~
plural.ity of valves 110 and groutld engaging feet has comc to be prefcrred.
DI~SLI~I Pl Il 0~ t!~ I~RE~SENTLY P~~EFERRI;:D E:M130DIMT;~N'r Re~rring now to FiguIes 5-8, a sccond embodi-ment is shown, to illustrate use of the tong raising and lowering means to power a flow-dividing valve. This valve receives the supply of pressurized treating liquid and successive].y supplies it in a repeating pa~tern to : -each of a plura].ity of supply lines leading to the res-pective sets of tines. According to the pattern, only .-. a set of tines which is at the moment plunged into the .
ground receives the pressurized supply of treatinq liquid. :~
Thus this embodiment eliminates a need for valves on -- 15 each set of tines, and ground engaging feet.
As with the first-described embodiment, the second is most expeditiously provided by modifying an existing, commercially available machine, for instance a Ryan Greensaire turf aerator, model WG24-1. The latter ~.
machine includes a frame 210 on which is mounted a 4-cycle gasoline engine 212. Ground engaging wheels 214 are provided to be driven by the engine through suitable clutch and transmission means to propel the machine about the surface being treated, for instance a golf course green. ~ transversally extending row of generally vertically oricnted bearings 216 is provided on the - frame. Each bearing 21G sl.idingly receives a rod 218.
' - ~.5 -~, :-,~. : -- '' ~3 3~g crall~ shaft 220 e~ends ~ransversally between addi-tiona] hearillgs on the frame. Its crank portions are pivot~l]y connect~ to respective ones o the rods 218 by connec~ing rods 222. The engine rotates the crank~
shaft 220 through suitablc clutch and~transmission means which arc shown including an endless drive chain 224.
Before modification, th~ turf aerator has pairs of replaceahle, downwardly directed hollow tines mounted on the lo~er ends of the rods 218. Thus, as the turf aerator is propelled over the surface undergoing treatment, the pairs of tines are successively plunged into the turf and then withdrawn, each tine removing a soil and thatch core from the turf. This particular model turf aerator puts thirty-six holes each three inches deep in each square foot of turf. The cores are typically from 1/4 inch diaméter to 5/8 inch diameter, depending on the size of hollow tines being used. ~ -In modifying the tur~ aerator, the hollow tines are removed and a soil treating liquid injector kit is mounted Oll the machine.
The soil treating injector kit includes a xotary, flow-dividing valve 226, an inlet conduit 228, a plurality of outlet conduits 230 and a corrcsponding plurality of dual tong soil treating liquid injectors 232. (In the em~odiment shown, there are six.) The injectors 232 are su~stantially as shown in Fi~re 4, excepting that in thc em~odim~n~ o Figures ..
- lG -- , , ,:
5-8 foot 13~ an~ the valvc ~ody 110 are eliminated anfl a cap is installcd at 84 so that there is an open co~nuni-cation between each respective ou~let conduit 230 and the tong openings 132.
~he outlet conduits 230 each pass through and are secured to a mounting bax 234 which is, in turn, mounted at 236 on the frame 210. At their upstream , ends, the six outlet ~onduits 230 terminate in respec~ , ,~
tive fittings 23~ which connect them, respectively, to ; ' six outlet ports 240 on the flow-dividing valve 226. ' The flow-dividing valve 226, in the example shown, has a three-part housing which includes an inlet portion 242, an outlet portion 244 and a tubular spacer 246. A bracket 248 secures between the housing inlet portion 242 at 250 and the frame 210 to mount the flow-dividing val~e on the frame.
Cylindrical bosses 252, 254 on the inlet an~ ' outlet portions 242, 244 of the valve housing snugly fit in the opposite ends of the tubular spacer 246 and O-rings provide,respective seals at 256, 258.
, A radiating flange 260 on the outlet portion 244 of the housing is provided with a circle of bolt holes 262 in axial alignmont with a correspondiny plurality of threaded sockets 264 in the axially inner end of the inlet portion 242 of tho housing. Respective bolts are inserted through the holcs 262 and threaded tightly in the sockets 264 to hold the housing together.

Thus, the space within the tubular spacer 2~6, axially between the bosses 252, 254provides a valve chamber 266. An inlet port 268 proceeds through the inlet portion 242 of the housing to communicate -~
throu~h the boss 252 with the chamber 266. The six outlet ports 240 proceed through the outlet portion 244 of the housing to communicate through the boss : 254 with the chamber 266. Adjacent their juncture with the outside of the housing, all of the ports 240, 268 are internally threaded to facilitate the ~:
respective conduit connections therewith.
Co-axially with the chamber 266, the outer end of the housing inlet portion is provided with a cylindrical recess 270. At its axially inner ..
end wall or shoulder 272, the recess 270 has a smaller diameter throughbore 274 which communicates with the chamber 266. .;
Astub shaft 276 extends through the . ~.
~: throughbore 274 and a short way into the chamber 266.
The shaft 276 also extends a substantial way out of the housing inlet portion through the mouth of the recess 270. Bearing sets 278, 280 received in the recess 270 journal the shaft 276 for rotation. An ~ .
0-ring seal 282 between shaft 276 and the through- ~`
. 25 bore 274 maintains the sealed integrity of the valve :: :
chamber 266.
Within the ~alve chamber 266, an annular drive `: ~.
yoke 284 is secured by set screw means on the axial -~
short portion 288 of the shaft 276. The drive yoke 284 .~ .
: , . . .
: . . . ~, . : .
includcs a pair of diametrically spaced, axially projecti.ng dri.ve pins 290 which extend toward the boss 254.
The pins 290 are slidin~31y received through corres~onding openi.ngs 292 in the outer rim of a valve body 294. In the instance shown, the valve body 294 is constituted by a pair of rigid rings 296 applied against opposite faces o$ a sheet 298 of lubri~cous plastic material, such as polytetrafluoroethylene. This assembly is held together with a plurality of rivets 300. The sheet 298 has a single eccentric opening 302 at the same radial distance as that of the communication of the six outlet ports 240 with the chamber 266.
- - Thus, 25 the shaft 276 is rotated, the drive yoke 284 correspondingly rotates the valve body 294 causing the eccentric opening 302 to successively momentarily align with each of the six outlet ports 240.
Pressurized soil treating liquid which flows into the valve chamber 266 through the inlet port 268 passes -20 through the eccentric opening 302 and issues out of each of the several outlet ports 240 in turn.
An inlet conduit 304 extends between a fitting 306 connecting it to the inlet port 268 and a fitting 308 secured on the mounting bar 234.

TIIF, Ol~IGI;~ALL.Y PRF:FI~RRl~D EMBOI)IMENT
_ _ _ _ The pre~surized liquid injector 10 includcs an a~plicator unit 12 connectcd by a high pressure hose linc 14 to a pressurized treating liquid supply 16.
In the instance depicted, the supply 16 takes the form of a tank wagon or the like 18 having a com-pressor 20 for placing the treating l~iquid under e.g.
150-600 p.s.i. The supply 16 may be e.g. from an agricultural orchard spraying unit, with the hose line 14 connecting to the applicator unit 12 rather than to a tree spraying wand.
The applicator unit 12 includes a frame 22 having right and left rear wheels 24 and a steering system comprising a two wheeled bogie or truck 26 journalled with respect to the frame 22 at 28 and having a forwardly projecting steering bar or tiller 30. A
gasoline engine 32 is shown mounted on the frame and equipped for driving the wheels 24.
The frame further includes an inverted yoke 34 which at 36 mounts a crank shaft 38 having~ e.g, six angularly disparate, axially spaced offset cranking portions 40.
(Conventional drive interruption~ clutch means are provided ~or disengaging the engine 32 from either the wheels 24 or the crank shaft 38).
, ,, ::
~a~3~s Each cranking portion 40 has a crank arm 42 journalled thereon which terminates in a clevis 44 which is in turn pivotally pinned at 46 to the upper end of a push rod 48 slidably mounted in a sleeve bearing 50 fixed on the rame 22.
Each push rod 48 has a dual tong injector unit 52 mounted thereon below the respective sleeve bearing 50.
In the instance depicted (see especially -Y 10 Figures 3 an~ 4) each dual tong injector unit 52 includes a body 54 which may be cast, although an -example fabricated by welding from plate and tube : :
is illustrated. The body 54 comprises a base plate 56 having a lateral projection 58 split at 60 leading to a vertical opening 62. A threaded lateral o ening 64 crosses the split 60 and receives a cap screw 66 for narrowing the split 60 to construct the opening :
62 for securing the body 54 on the respective push ,~
rod 48. Two laterally spaced vertical openings 68 ~:
receive the upper ends of two respective tubular injec-tor tongs 70. The latter are sealed with respect to the respective openings 68 by sealing ring means 72 and secured in place by nuts 74. ~;
Within the body 54, passageways 75 communicate the two tongs with a valve housing 76 incorporated ~:
into the body 54. :~
As depicted, the valve housing 76 is an up-right, composite tubular member 78 having its through-bore 80 in communication with the passageway 75 at ::
the lower end of the throughbore 80.
,i~.,~
, ' .,,, . .:
:, . - , . . . , : ~
3~
The lower most portion 82 of the housing ~;
76 is internally threaded at 84 to receive the ex-teriorly threaded lower end of an intermediate tubular portion 86. An internal seal is made between these two parts at 88 and an external seal is made between them at 90. Intermediate these seals 88, 90, the parts 82 and 86 are radially spaced from one another circumferentially to define an annular chamber 92 the throughbore 80 flares upwardly to provide a frusto~
conical valve seat 94. Above the valve seat 94 radial bores interconnect the throughbore 80 with the chamber 92. A conduit 98 connects the chamber 92 with a hose fitting 100.
The valve housing intermediate portion .
upwardly terminates in an internally threaded portion 102 which receives the externally threaded lower end .. .
104 of an upper portion 106. A seal is formed be-tween these parts at 108.
A valve body 110 is reciprocatingly received in the throughbore 80 above the valve seat 94. It includes a conical tip 112 preferably made of re-silient material such as nylon for sealing against the valve seat 94 when the valve is closed. The body 110 has a metal rod 114 as a stem. This rod 114 ; :~;
projects up the throughbore 80 and out the upper end thereof through an annular gland nut 116 which seals with the rod at 118. ~ :~
A compression coil spring 120 encircling the rod 114 within the bore 80 gains purchase between the ;~
::
~ ~. . .
~.,. ~ .
-11 - ~, :: , . . . . .
enlarged head 122 of the valve body and the lower end of the valve housing upper portion 10~ to nor-mally bias the valve toward a closed condition.
Outside the housing, a valve stem pusher 124 is mounted on the stem 114 with securement means 126. Accordingly, upward force on the pusher 124 raises the valve body away from the valve seat against the restoration force of the spring 120 permitting liquid supp~ied under pressure via the hose fitting 100 to : 10 flow through the conduit 98, into the chamber 92, through the radial bores 96, into the throughbore 80, down between the valve body tip 112 and seat 94, into ; the passageways 75, into the two tongs through radial passageways 128, down the throughbores 130 of the two respective tGngs and out the radia~ing openings 132 provided just above the solid, pointed lower tips 134 of the two respective tongs.
Each dual tong injector unit body 54 further - includes a tubular, generally vertical, valve actuator mounting sleeve 136 disposed adjacent the valve housing.
The sleeve 136 acts as a sleeve bearing for an actuator ; .
rod 138 which has a lower end 140 protruding below the lower end of the sleeve 136 for engagement with the ~ ~
surface of the ground. The re~ion 144 near the upper ~ -` 25 end of the rod 138 is externally threaded and protrudes above the upper end 146 of the sleeve 136 and threadably mounts an internally threaded flange member 148. The latter has a flange portion 150 which protrudes laterally 4i~349 into the external lateral groove 152 of the valve stem pusher 12~, connecting the valve stem to the actuator so that when the actuator is pushed up by contact of the lower end 142 with the ground, the valve is opened until ~urther rotation of the crank -:
shaft 38 raises the dual tong injector unit under consideration sufficiently to permit the actuator rod 138 to begin to lower. It should be apparent ~hat rotative adjustment of the flange member 148 rela~ive to the rod 138, by threading, vertically adjusts the deposition of the lower end of the rod ;.
138 with respect to the rest of the particular dual tong injector unit and the surface of the ground, thus ~ .
providing a means for increasing and decreasing the : :~
proportion of the vertical indexing cycle for the ;~
respective dual tong injector unit during which the i~
associated valve is open and the two associated ~-~ll tongs injecting. The earlier and later a valve is open the more liquid will be injected and the thicker the band of injection will be reaching the same depth ;-~
but extending up closer to the surface of the ground) - ~;`
other factors being equal. ~ ::
When being used, for instance ~o treat the turf of a golf course green, the tank wagon 18 is drawn i;
to its border and its contained treating liquid delivered ' under high pressure by the pump 20 through the hose line 14 to the application unit 12. That unit is led over the surface of green, much like a power mower. As the .~ . .
, , ~, .
'. ' ?~i f.,~
:~3~9 dual tong units 52 are indexed up and down by the crank shaft 38, the respective actua~or rods 138 strike the ground during the downstrokes opelling the respective valvcs 110 while the respective injector tips are below s the upper surface of the turf.
Each hose fitting 100 connects a flexible hose 160 with a manifold 162 mounted on the frame 22. The manifold 162 has an inlet pipe 164 which connects at its upper end with the high pressure hose 14 to receive a supply of treating liquid from the compressor 20 on the tank wagon 18. ~
Being able to treat with injections at relatively high pressure, while separating t~e bulX :
supply and pressurization bulk and weight to a relatively stationary place (the tank wagon) so that it does not ; have to be lugged around with the applicator unit makes the latter much more mobile and versatile.
There are instances where it is disadvantageous to operate the valves 110 from push rod engagement with the ground at 140. In such instances, suitable camming means may be provided which work from the cam shat 38 to cause the actuators 124 to relatively lift with res-pect to the valve housing 76 when the respective bodies 56 are moved downward because of ~heir securement on the respective vertically réciprocated rods 48.
In fact, as described bclow, an embodiment of - the latter sort, which eliminates the ne~d for a ~834~
plural.ity of valves 110 and groutld engaging feet has comc to be prefcrred.
DI~SLI~I Pl Il 0~ t!~ I~RE~SENTLY P~~EFERRI;:D E:M130DIMT;~N'r Re~rring now to FiguIes 5-8, a sccond embodi-ment is shown, to illustrate use of the tong raising and lowering means to power a flow-dividing valve. This valve receives the supply of pressurized treating liquid and successive].y supplies it in a repeating pa~tern to : -each of a plura].ity of supply lines leading to the res-pective sets of tines. According to the pattern, only .-. a set of tines which is at the moment plunged into the .
ground receives the pressurized supply of treatinq liquid. :~
Thus this embodiment eliminates a need for valves on -- 15 each set of tines, and ground engaging feet.
As with the first-described embodiment, the second is most expeditiously provided by modifying an existing, commercially available machine, for instance a Ryan Greensaire turf aerator, model WG24-1. The latter ~.
machine includes a frame 210 on which is mounted a 4-cycle gasoline engine 212. Ground engaging wheels 214 are provided to be driven by the engine through suitable clutch and transmission means to propel the machine about the surface being treated, for instance a golf course green. ~ transversally extending row of generally vertically oricnted bearings 216 is provided on the - frame. Each bearing 21G sl.idingly receives a rod 218.
' - ~.5 -~, :-,~. : -- '' ~3 3~g crall~ shaft 220 e~ends ~ransversally between addi-tiona] hearillgs on the frame. Its crank portions are pivot~l]y connect~ to respective ones o the rods 218 by connec~ing rods 222. The engine rotates the crank~
shaft 220 through suitablc clutch and~transmission means which arc shown including an endless drive chain 224.
Before modification, th~ turf aerator has pairs of replaceahle, downwardly directed hollow tines mounted on the lo~er ends of the rods 218. Thus, as the turf aerator is propelled over the surface undergoing treatment, the pairs of tines are successively plunged into the turf and then withdrawn, each tine removing a soil and thatch core from the turf. This particular model turf aerator puts thirty-six holes each three inches deep in each square foot of turf. The cores are typically from 1/4 inch diaméter to 5/8 inch diameter, depending on the size of hollow tines being used. ~ -In modifying the tur~ aerator, the hollow tines are removed and a soil treating liquid injector kit is mounted Oll the machine.
The soil treating injector kit includes a xotary, flow-dividing valve 226, an inlet conduit 228, a plurality of outlet conduits 230 and a corrcsponding plurality of dual tong soil treating liquid injectors 232. (In the em~odiment shown, there are six.) The injectors 232 are su~stantially as shown in Fi~re 4, excepting that in thc em~odim~n~ o Figures ..
- lG -- , , ,:
5-8 foot 13~ an~ the valvc ~ody 110 are eliminated anfl a cap is installcd at 84 so that there is an open co~nuni-cation between each respective ou~let conduit 230 and the tong openings 132.
~he outlet conduits 230 each pass through and are secured to a mounting bax 234 which is, in turn, mounted at 236 on the frame 210. At their upstream , ends, the six outlet ~onduits 230 terminate in respec~ , ,~
tive fittings 23~ which connect them, respectively, to ; ' six outlet ports 240 on the flow-dividing valve 226. ' The flow-dividing valve 226, in the example shown, has a three-part housing which includes an inlet portion 242, an outlet portion 244 and a tubular spacer 246. A bracket 248 secures between the housing inlet portion 242 at 250 and the frame 210 to mount the flow-dividing val~e on the frame.
Cylindrical bosses 252, 254 on the inlet an~ ' outlet portions 242, 244 of the valve housing snugly fit in the opposite ends of the tubular spacer 246 and O-rings provide,respective seals at 256, 258.
, A radiating flange 260 on the outlet portion 244 of the housing is provided with a circle of bolt holes 262 in axial alignmont with a correspondiny plurality of threaded sockets 264 in the axially inner end of the inlet portion 242 of tho housing. Respective bolts are inserted through the holcs 262 and threaded tightly in the sockets 264 to hold the housing together.

::. , ; . . . . . .. . . .
~L0~349 :
Thus, the space within the tubular spacer 2~6, axially between the bosses 252, 254provides a valve chamber 266. An inlet port 268 proceeds through the inlet portion 242 of the housing to communicate -~
throu~h the boss 252 with the chamber 266. The six outlet ports 240 proceed through the outlet portion 244 of the housing to communicate through the boss : 254 with the chamber 266. Adjacent their juncture with the outside of the housing, all of the ports 240, 268 are internally threaded to facilitate the ~:
respective conduit connections therewith.
Co-axially with the chamber 266, the outer end of the housing inlet portion is provided with a cylindrical recess 270. At its axially inner ..
end wall or shoulder 272, the recess 270 has a smaller diameter throughbore 274 which communicates with the chamber 266. .;
Astub shaft 276 extends through the . ~.
~: throughbore 274 and a short way into the chamber 266.
The shaft 276 also extends a substantial way out of the housing inlet portion through the mouth of the recess 270. Bearing sets 278, 280 received in the recess 270 journal the shaft 276 for rotation. An ~ .
0-ring seal 282 between shaft 276 and the through- ~`
. 25 bore 274 maintains the sealed integrity of the valve :: :
chamber 266.
Within the ~alve chamber 266, an annular drive `: ~.
yoke 284 is secured by set screw means on the axial -~
short portion 288 of the shaft 276. The drive yoke 284 .~ .
: , . . .
: . . . ~, . : .
includcs a pair of diametrically spaced, axially projecti.ng dri.ve pins 290 which extend toward the boss 254.
The pins 290 are slidin~31y received through corres~onding openi.ngs 292 in the outer rim of a valve body 294. In the instance shown, the valve body 294 is constituted by a pair of rigid rings 296 applied against opposite faces o$ a sheet 298 of lubri~cous plastic material, such as polytetrafluoroethylene. This assembly is held together with a plurality of rivets 300. The sheet 298 has a single eccentric opening 302 at the same radial distance as that of the communication of the six outlet ports 240 with the chamber 266.
- - Thus, 25 the shaft 276 is rotated, the drive yoke 284 correspondingly rotates the valve body 294 causing the eccentric opening 302 to successively momentarily align with each of the six outlet ports 240.
Pressurized soil treating liquid which flows into the valve chamber 266 through the inlet port 268 passes -20 through the eccentric opening 302 and issues out of each of the several outlet ports 240 in turn.
An inlet conduit 304 extends between a fitting 306 connecting it to the inlet port 268 and a fitting 308 secured on the mounting bar 234. A control valve 310 is shown incorporated in the inlet conduit 304 adjacent the fitting 308. Both the inlet conduit 304 and the outlet conduits 230 are shown constituted by ~lexible, hi~h pressure hose lines.
.: - : . :
Outside the housing of the flow-dividing valve 226, a drive sprocket 312 is secured on the shaft 276. The teeth of the sprocket 312 are meshed in the roller chain 224, so that when the applicator :
is being propelled upon a surface being treated, and the tong raising and lowering crank shaft is being rotated, the running roller chain 22~ rotates -the sprocket 312 and thus operates the valve 225, In consequence, high pressure liquid treating fluid supplied to the inlet conduit 304 at the fitting 308 ~ : .
is di~ided in the valve 226 and sent in sequential ;
