Abstract

ABSTRACT

A water volume indicator for an animal waterer which includes a balance beam of substantial mass which supports a water receptacle such that when water is removed the balance beam will pivot to open a valve to allow water to be fed into the bowl and which has a switch which is actuated by movement of the balance beam to close a circuit to actuate a timer such that the time that the valve was opened to add water can be determined. This al-lows the operator to determine how much water has been re-moved from the bowl by the horse or other animal and thus the amount of fluid intake by the animal is deter-mined.

Description

SPECIFICATION
This invention relates in general to animal waterers and in particular to a novel animal waterer which measures the amount of water that has been consumed by an animal.
Certain animals such as horses and particular race horses, it is necessary to ~uickly detect when the animal stops drinking. This indicates that there is a danger to the animal's health. Prior art automatic waterers always maintained a filled drinking bowl and do not allow measurement of the amount of water which has been drunk by the animal. Thus, if the animal stops drinking this may not be detected until the animal has become very ill such that its health may be endangered.
The present invention comprises a combination o~ an animal water which has an a~tomatic timer that is actuated by the balance beam which actuates the switch to close a circuit to an interval timer such that the operator may monitor the amount of water being drunk by an animal during a particular period by observing the amount of time that the valve has been opened. The timer can be reset and thus the amount of liquid intake can be measured .~'`

for different intervals as selected by the operator who immediately knows when the animal has stopped drinking which would indicate danger to the animal.
Other objects, features and advantages of the invention will be readily apparent from the following des-cription of certain preferred embodiments thereof taken in con~unction with the accompanying drawings although variations and modifications may be effected without depart-ing from the spirit and scope of the novel concepts of the disclosure, and in which: -ON THE DRAWINGS
Figure l is a side sectional view of the invention;
Figure 2 is a cut-away top sectional view of the invention; and Figure 3 is a detail view illustrating the time interval switch of the invention.
Figures 1 and 2 illustrate the novel animal waterer 10 of the invention which has generally cylindrical-shaped housing ll and a top cover member 12 with a frusto conical opening 13 thorugh which the animal can drink.
cross-frame member 25 is connected across the housing 11 and a frame member 32 best shown in Figure 3 is attached to the frame member 25 and has upwardly extending sides 35 and 40. A balanced beam 22 with downwardly extending sides 41 and 42 fits over the sides 35 and 40 of frame member 32 and a pivot pin 28 extends through openings formed in the walls 35, 40, 41 and 42 and carter keys 29 and 31 hold the pivo~ pin 28 in position. Pivot beam 22 carries a counterweight 83 which connects to the portion 86 of bracket 81 which is formed with a slot ~2 through which a bolt 84 extends so as to allow adjustment o-f the counter-~Lv? 623~

weight 83. A bowl supporting frame comprises the members17, 18 and 19 which are connected at their top by a ring 21 in which the bowl 14 is received. A water supply inlet pipe 15 connects to a valve 36 and has an outlet 16 which extends along the outside of the bowl 14 and has a curve portion for supplying water into the bowl 14. A bracket 46 is connected by bolts 47 and 48 to the cross-frame me~ber 25 and has a switch 51 which might be a micro switch that has a flexible actuating lever 57 as best shown in Figure 3 which can engage the switch contact 58 to depress it.
A bracket 61 is connected to the balance beam 22 by a bolt 62 and has an ad~ustable screw 53 which is engageable with the flexible spring actuator 57. A pair of screws 52 and 53 comprise switch contacts for the switch 51 and leads 54 and 56 are attachable thereto. The leads 5~ and 56 extend to a connector ~0 which mates with a connector 91 that has leads 92 and 93 that are connected to an interval timer 94 that has a battery 96, an indicator 97 that can be read against the indicia 98 and a test switch 99.
In operation, the bowl 14 is filled through the valve 36 until the counterbalance 83 is overcome by the weight of the water in the bowl 14 such that the balance beam moves to the position illustrated in Figure 1 which closes the valve 36 to shut off the water. The interval timer 94 is reset and tested by a button 99 to deter~ine the condition of the battery 96.
The screw 63 is adjusted until its end causes the spring 57 to actuate the switch contact 58 thus closing the switch 51 when the balance beam is in the down position when the valve 36 is opened to supply water to the bowl 14.

Thus~ as an animal drinks from the bowl, the liquid will reach a level wherein the counterbalance $3 will overcome the weight of the water and the balance beam will pivot clockwise relative to Figure 1, thus opening valve 36 and simultaneously the screw 63 will engage the spring contact 57 and actuate switch contact 58 closing the circuit through switch 51. This connects the battery 96 to the needle 97 so that it will move clockwise relative to Figure 1 relati~e to the indicia 98 to indicate the time that the valve 36 remains open. Since the valve 36 can be calibrated such as for example it might admit 1 1/2 gallon per minutethe elapsed time indicator ~4 will indicate the amount of water that has been supplied to the bowl 14 in a known interval.
Thus, for example, if the valve 36 allows 1 1/2 gallons per minute to enter the bowl and the interval clock 94 indicates that ela~sed open time of the valve is 10 minutes it is known that fifteen gallons has been supplied to the bowl 14 during a particular time and the animal such as a horse will have drank this ~uantity of water.
If the operator observes that the horse for example is not drinking or is drinking small quantities of water, this immediately gives him a warning that the animal is ill and measures must be taken to remedy this situation.
Since such condition is detected early, the chances of successful treatment of the animal are greatly enhanced.
Although the invention has been described with re-spect to preferred embodiments, it is not to be so limited as changes and modifications may be made therein which are within the ~ull intended scope of the invention as defined by the appended claims.
