referring now to fig1 the device is illustrated generally at 10 . the stump treating device comprises a reservoir 12 and a fluid application device 14 . in the embodiment illustrated in fig1 the reservoir 12 is an elongated cylindrical handle which is hollow . preferably the handle is of suitable length to enable the operator to hold the device with two hands and to apply the fluid application device 14 to a freshly cut stump without unnecessarily bending . fluid is delivered from the reservoir 12 to the fluid application device 14 by means of a conduit illustrated generally at 16 . the stump treating device 10 comprises a housing 20 which is attached to the reservoir 12 . the housing 20 may be attached by means of a threaded fitting or other similar attachment means . the housing 20 , as shown in fig2 defines a cup 22 . the cup 22 serves the function of locating the fluid application device 14 . in the embodiment shown in fig1 and 2 , the fluid application device 14 is in the form of a sponge . the sponge may be held in the cup 22 by means of inwardly extending projections or ribs 24 . a plurality of ribs 24 may be distributed about the inner circumference of the cup 22 to maintain the sponge within the cup 22 . from reference to fig2 it will be observed that there is a value 30 . the valve 30 controls flow of fluid from the reservoir to the fluid application device 14 . advantageously the valve 30 includes a valve stem 32 which projects from the cup 22 . the valve stem 32 is attached to a closure 34 . the closure 34 is biassed to the flow blocking position by a spring 36 . to open the closure 34 , the valve stem 32 is pushed so that it travels longitudinally along its general longitudinal axis in the direction of arrow 38 , thereby pressing the spring 36 and permitting fluid to flow through the conduit 16 to the fluid application device 14 . when pressure against the valve stem 32 is removed , the spring 36 functions to move the closure 34 to the closed position . in order to use the device shown in fig1 and 2 , the reservoir is opened by removing the filling cap 40 from the reservoir 12 . the reservoir 12 is then filled with suitable herbicidal fluid . this may be an aqueous solution mixed as appropriate for the particular herbicide . fluid will then fill the reservoir 12 and will be held in the reservoir by the valve 30 . when it is desired to apply herbicide to a freshly cut stump , the housing 20 is placed adjacent to a convenient surface . this may be the ground or the stump or other suitable surface such as a rock or the like . the suitable surface is then used as an anvil and the housing 20 pressed against the surface so that the surface contacts the valve stem 30 opening the valve closure 34 . fluid will then flow from the reservoir under the effect of gravity to saturate the sponge 14 to the desired level . the housing is then removed from the convenient surface to stop the flow of fluid to the sponge . with the sponge then in a suitably saturated condition , the sponge may be applied to the freshly cut surface of the stump thereby applying the fluid herbicide directly to the freshly cut stump . fig3 illustrates an alternate embodiment of the invention . the device illustrated generally at 50 in fig3 has several component parts . the device includes a clamp 52 , a reservoir 54 , an conduit 56 , an applicator housing 58 and an adjustable support means 60 . the clamp 52 is comprised of a first clamp bracket 66 and a second clamp bracket 68 . the two clamp brackets 66 and 68 each have a substantially right angular central portion adapted for containing therebetween , the shaft of a gasoline powered clearing saw . the shaft upon which the clamp is to be installed in shown as 69 in fig3 . in order to adjust the clamp and affix it tightly to the shaft of the saw , screws 70 and 72 may be tightened to adjust the spacing between the clamp members 66 and 68 to accommodate differing sizes of shaft for rotary saws . the reservoir 54 may be any convenient size or configuration . the reservoir may be filled through a fill opening 76 . the reservoir may be carried by means of a strap 78 . the strap 78 may be placed over the operator &# 39 ; s shoulder to support the reservoir on the operator . various other kinds of straps such as positioning the reservoir as a back pack , fanny pack or side pack may all be utilized . the conduit 56 is attached to the reservoir to deliver fluid from the reservoir . preferrably the conduit 56 comprises two portions 56a and 56b . to assist in delivery of fluid from the reservoir , the conduit 56a advantageously comprises a pump 80 . pump 80 may be hand operated and advantageously comprises a squeeze bulb with check valves . the conduit 56a advantageously terminates in a free end having a first quick connect , disconnect coupling 82 . the conduit 56 may be of any convenient length . the applicator housing 58 comprises a substantially cup shaped enclosure 86 . mounted within the cup shaped enclosure is a fluid application device 88 . the fluid application device 88 is preferentially a sponge . enclosure 86 includes locating means 87 for holding and positioning the sponge 88 within the enclosure 86 . the applicator housing includes an inlet conduit 90 . the inlet conduit 90 contains a check valve 92 . the applicator housing also includes a shorter length of conduit 56b . the conduit 56b advantageously terminates in a free end having a second quick disconnect , connect coupling 96 . the first and second couplings 82 and 96 are configured for interaction to create leak free fluid flow along conduit 56 from resevoir 54 to check valve 92 . the applicator housing includes a fitting 98 into which is fixed a rod 100 . the rod 100 is received within a bore 101 contained in a support arm 102 . a set screw 104 tightens against the rod 100 so that when the set screw 104 is adjusted the rod 100 cannot move either longitudinally or angularly with respect to the support arm 102 . the support arm 102 terminates in a threaded boss 106 . threaded boss 106 is received within a threaded bore 108 in the clamp bracket 68 . the threaded boss 106 and bore 108 provides longitudinally adjustable spacing and angularly adjustable relationship of rod 100 relative to clamp 52 . in order to lock the support arm 102 at the desired location and angle a lock nut 110 is threadably received on the threaded boss 106 for jamming against the clamp bracket 68 . in order to use the device shown in fig3 the device is first attached to a clearing saw . the clearing saw typically involves a gasoline engine , an enclosed drive shaft and a rotary saw blade . the enclosed drive shaft is enclosed within a generally cylindrical shaft . the shaft is typically of length of approximately five feet . the shaft may have attached to it a yoke for manipulating the saw blade . the device 60 is attached to the shaft of the powered rotary saw by disassembling the clamp 52 . brackets 66 and 68 are then placed around the shaft of the clearing saw at the end closest to the rotating saw blade . the support arm 102 is then installed in the bracket 68 and lock nut 106 is left in a loose condition . the rod 100 is then installed in the support arm 102 . it will be noted , the rod 100 is preferrably bent to include an offset portion so that rotating rod 100 about its general axis will change the amount of offset of the housing 58 relative to clamp 52 . the applicator housing may then be positioned with the enclosure 86 substantially adjacent to the safety guard on the saw and with the lower surface of the sponge 88 located substantially at or slightly above the plane of the saw blade . with the sponge 88 located in that position then the set screw 104 and the lock nut 110 are tightened to fix the location of the various adjustable parts . when using the device , the reservoir 54 is filled by introducing suitable herbicidal fluid through the fill opening 76 . the reservoir 54 is then supported on the body of the user by means of the strap 78 . the conduit 56 may advantageously be attached to the shaft of the saw by means of chord or plastic quick connect , disconnect ribbon type straps . the quick connect , disconnect fittings 82 and 96 are connected to one another to form a fluid path from the reservoir 54 directly to the sponge 88 . the pump 80 may be used to transfer fluid from the reservoir through conduit 56 , by check valve 92 and through conduit 90 directly to the sponge 88 . check valve 92 may be a spring loaded ball type check value with the spring biassing the valve to the closed position preventing fluid from draining from reservoir 54 through to sponge 88 . pressure from the pump overcomes the spring of check valve 92 to prevent fluid flow along the conduit 56 . fig4 illustrates the device of fig3 installed on a saw 200 . the saw has a gasoline powered engine 202 , and a shaft 204 . the shaft 204 terminates in a fitting 206 . the fitting supports a saw blade 208 for rotation . the motor 202 drives the blade 208 through a drive shaft which is journaled internally within the shaft 204 . the saw has a handle indicated generally at 210 which includes grips 212 and 214 . the grips 212 and 214 may include controls for operating the saw . the saw 200 includes a safety guard 216 . to use the combined device shown in fig4 the operator typically starts the motor by use of a pull chord . the device is used by grasping the device with the hand grips 212 and 214 and controlling the clutch and speed of the motor to drive the saw blade 208 . the device is steered by means of the hand grips 212 and 214 so that the saw blade 208 bears against the tree to be cut . the tree is cut by pressing the blade against the tree until the tree is cut through , leaving a stump . the device is then manoeuvred as necessary to bring the applicator housing 58 toward the freshly cut stump . if the sponge 88 is not already saturated with fluid then the operator releases one hand from one of the grips 212 or 214 and operates the pump 80 , delivering fluid from the reservoir 54 to the sponge 88 . the pressure from pump 80 unseats check valve 92 so that fluid may flow into the sponge 88 during the pumping action . when the sponge is suitably saturated , the sponge is then applied to the fresh cut surface . if the stump to be treated is smaller than the sponge , then the sponge is simply dabbed on top of the entire stump . if the stump is considerably larger than the sponge then the sponge is manoeuvred around the periphery of the stump so that the herbicide within the sponge is applied to all of the sap wood of the freshly cut tree . if a particularly large stump is being treated it may be necessary to pump additional fluid by means of hand pump 80 during the treating process . when the treating process has been completed , the operator then moves on to the next tree . it will be observed that with the stump treating device of either fig1 or the assembly as shown in fig4 an operator can efficiently both cut and treat stumps . because the fluid is applied by means of a fluid application device directly to the surface of the cut stump , there is efficient use and application of the herbicide . the herbicide is not brought into contact with anything other than the area touched by the sponge . this eliminates the effect of over spray and the treatment of stumps is independent of local wind conditions . in disclosing this invention with these preferred embodiments , it has been suggested that the preferred method of applying the herbicidal fluid to the freshly cut stump is a sponge . various other means of applying the fluid directly to the stump may also be utilized with the invention . by way of example , a bristle type device may also be used in which the fluid flows along the bristles . in addition , a pad - like device involving a plurality of holes on the backside to admit fluid to a pad and relying on the fluid to pass along and through the pad may also be utilized . while the above description has been made in association with two preferred embodiments , it will be appreciated that the present invention is susceptible to modification and change without departing from the fair meaning of the proper scope of the accompanying claims .
for treating freshly cut tree stumps to inhibit regeneration of the stump , the stump is coated with herbicide . the herbicide is applied to the stump by means of a sponge or other application device . the sponge is housed in a housing which is connected to a reservoir with a long handle . after a tree is cut , herbicide is applied to the fresh cut surface . the treatment device may be attached to a saw and include a reservoir carried by the saw operator . the herbicide application device is clamped to the shaft of the rotary saw and positioned adjacent the safety guide so that immediately after the tree is cut , herbicide may be applied to the fresh cut .
