preferred embodiments of the present invention are shown in fig1 through 3b , directed to a cattle foot - bath system 15 . the cattle foot - bath system is well suited for the treatment and cleaning of feet or hooves of the cattle . as shown in fig1 , the cattle foot - bath system 15 includes the semi - automated delivery of a concentrated medicinal agent 25 , the medicinal agent selected for the treatment of cattle feet . the concentrated medicinal agent 25 may be any medically active bactericide , fungicide , or viruscide , desired for use in a foot bath 50 with the cattle foot - bath system 15 of the present invention . preferably , the concentrated medicinal agent 25 is a concentrated “ formalin ” solution , which is formaldehyde in a water solution . formalin is especially useful in the preventive treatment of lameness associated with foot rot , and related diseases caused by bacterial infections of the hooves . the formalin concentrate is most preferably contained in a portable tank , conventionally referred to as a “ tote - tank ” 35 . because the tote - tank contains a concentrated solution of what may be an environmentally sensitive substance , the tote - tank is preferably placed within a containment 32 , as shown in fig1 through 3b . the containment prevents contamination of the environment external to the containment , if the tote - tank leaks . the concentrated medicinal agent 25 is preferably fed through the containment 32 at a containment penetration 33 , as shown in fig1 through 3b . most preferably , the feed is also controlled with a feed shut - off valve 34 , which acts as a safety valve to prevent leakage downstream of the containment . as shown in fig1 through 3b , the concentrated medicinal agent 25 is fed into a day - tank 40 . the day - tank holds the set quantity of the concentrated medicinal agent , providing an exact and consistent quantity for use with the foot - bath 50 . the day - tank is sized to receive and precisely measure a quantity of the concentrated medicinal agent . preferably , the day - tank contains five u . s . gallons , when filled , but could hold more or less material , depending on the activity and strength of the concentrated medicinal agent , the final volume of the foot - bath , and ultimate desired concentration of the resultant mixture within the foot - bath . for the most preferred concentrated medicinal agent 25 , a standard formalin concentrate , of 37 % formaldehyde in water by volume is employed . after filling , the day - tank feed valve 43 is closed , and the day - tank 40 is ready for delivery to the foot - bath 50 . the filled day - tank quantity of concentrate is mixed in the foot - bath 50 with a set quantity of a dilution water 60 . preferably , for the five - gallon day - tank , with the 37 % solution , forty - five u . s . gallons of the dilution water are employed . this results in a volume of fifty u . s . gallons of a working mixture 52 within the foot - bath having a concentration of 3 . 7 % formaldehyde in water by volume , or one - tenth of the original concentration . the dilution water may be any source of pure or recycled water for use by the cattle . specifically , as shown in fig1 , 3 a and 3 b , a day - tank feed valve 43 is employed to control an infeed flow of the concentrated medicinal agent 25 into the day tank 40 , through a concentrated feed - pipe 41 . after the day - tank is filled , the day - tank feed valve is closed and a day - tank drain valve 44 is opened . the day - tank drain valve controls an outlet flow of the concentrated medicinal agent drained from the day - tank , through a day - tank drain pipe 46 . as shown in fig1 through 3b , the cattle foot - bath system 15 preferably includes a vent 42 connecting the day - tank 40 to the concentrated medicinal agent 25 this component recycles any vapors emitted from the day - tank , especially during filling , and if the day - tank is overfilled , the overflow is directed back to the tote - tank of concentrated medicinal agent . preferably , prior to the opening of the day - tank drain valve 44 , to fill the foot - bath 50 , the foot - bath is partially filled with the dilution water 60 , by the opening of a dilution water valve 61 . this may be additionally accomplished with either a metered valve , tank graduations on the container or tank holding the dilution water , or a mark on the foot - bath . alternatively , the contents of the day - tank can be released into the foot - bath by opening the day - tank drain valve and the dilution water then added to “ top - off ” the foot - bath at a set fill point . with the pre - measured contents of the day - tank and the added dilution water , the foot - bath contains the working mixture 52 , which includes the concentrated of the medicinal agent diluted to desired , effective level . this process for the cattle foot - bath system 15 is repeatable with the same exact results , without requiring exacting volumetric measurements or oversight by technically skilled personnel . preferably , the foot bath 50 is conventionally sized with capacity of fifty u . s . gallons . typically , the foot - bath has a length of approximately six feet in and is approximately three feet in width . the working mixture 52 should fill the foot - bath to a depth of approximately four to six inches . the foot - bath can be located at the exit lanes from a milking parlor , when employed for use in a dairy operation . typically , the foot - bath 50 is drained and recharged with fresh working mixture 52 on a daily basis . to drain the previously mixed , used or spent working mixture 52 from the foot - bath , a foot - bath drain valve 53 is employed , as located in fig1 through 3b . the working mixture is transferred as a waste water 70 , which may be any appropriate tank , lagoon or pond . the formalin active ingredient of the preferred concentrated medicinal agent 25 is converted into a benign by - product quickly , attributable to degradation from heat , sunlight and cattle urine . the waste water may be reclaimed for other uses in the farm , ranch or dairy employing the cattle foot - bath system 15 . an alternative embodiment of the cattle foot - bath system 15 is shown in fig2 a and 2b , employing a three - way valve 75 . the three - way valve is preferably a conventional , three - way diverter type of valve , with an inlet and a valve with the ability to select one of two outlets . the three - way valve replaces the function of the day - tank feed valve 43 and the day - tank drain valve 44 . the three - way valve also assures that the day - tank 40 is used as a measuring tank , and not drained as it fills , or simply employed as a flow - through passage from the tote - tank to the foot - bath 50 . fig2 a shows the three - way valve in a day - tank fill position a , which serves to fill the day - tank , while preventing the day - tank from draining into the foot - bath . fig2 b shows the three - way valve in a day - tank drain position b , which serves to drain the day - tank , while preventing the day - tank from filling with the concentrated medicinal agent 25 . additionally , the three - way valve 75 may include a back - flow preventer 76 . the back - flow preventer is a standard flow control device that halts the reverse flow of liquid through the valve . in position a , as shown in fig2 a , the back - flow preventer stops the flow of concentrated medicinal agent 25 , back to the tote - tank 35 from the day - tank 40 . in position b , as shown in fig2 b , the back - flow preventer stops the flow of concentrated medicinal agent 25 , back to the day - tank 40 from the foot - bath 50 . in an additional alternative embodiment of the cattle foot - bath system 15 , a valve interlock 80 may be included , to further improve the reliability of operation for the cattle foot - bath system 15 . as with the three - way valve 75 , the valve interlock assures that the day - tank 40 is used as a measuring tank , and not drained as it fills , or simply employed as a flow - through passage to the foot - bath 50 . fig3 a shows the valve interlock in a day - tank fill position a ′, which serves to open the day - tank feed valve 43 , while closing the day - tank drain valve 44 . fig3 b shows the valve interlock in a day - tank drain position b ′, which serves to drain the day - tank , while preventing the day - tank from filling with the concentrated medicinal agent 25 . the valve interlock 80 may be a mechanical or electrical device that prevents flow through the day - tank drain valve 44 , while the day - tank feed valve 43 is in the open position , and conversely prevents flow through the day - tank feed valve , while the day - tank drain valve is in the open position . an interlock bar can be employed to serve as the valve interlock , or a solenoid powered electro - mechanical interlock can be utilized , for example . for convenience in operation of the cattle foot - bath system 15 , the day - tank 40 may be mounted directly to the tote tank of the concentrated medicinal agent 25 , with a day - tank tray 90 , as shown in fig1 . with the day tank tray attachment to the tote tank , the day tank can be placed within the containment 42 , or straddle the containment as preferred . if the day - tank is placed within the containment , the containment penetration 33 is placed on the outflow from the day - tank , in the day - tank drain line to the foot bath 50 . having now described the present invention , to those skilled in the art to which it pertains , it may become apparent that the need to make modifications without deviating from the intention of the invention . in compliance with the statutes , the invention has been described in language more or less specific as to structural features and process steps . while this invention is susceptible to embodiment in different forms , the specification illustrates preferred embodiments of the invention with the understanding that the present disclosure is to be considered an exemplification of the principles of the invention , and the disclosure is not intended to limit the invention to the particular embodiments described . those with ordinary skill in the art will appreciate that other embodiments and variations of the invention are possible , which employ the same inventive concepts as described above . therefore , the invention is not to be limited except by the following claims , as appropriately interpreted in accordance with the doctrine of equivalents .
