Abstract
"ELECTRONIC LIVESTOCK WATERING DEVICE"
ABSTRACT OF THE DISCLOSURE
Conventional stock watering devices include mechanical water level controls, floats and linkages within an immersion heater and usually bi-metallic strips are used to control temperatures. All of these compon-ents are easily corroded particularly when highly miner-alized water is often the only source. The present device eliminates all moving parts with the exception of an electronically controlled solenoid valve for opening and closing the water intake line. It is controlled by electronic sensors within an insulated stainless steel tank which includes a heat blanket bonded to the base thereof. Furthermore it includes an automatic shut down capability if there is no water in the tank. All of the controls are contained within an insulated casing which in turn may be maintained at a working temperature by means of a separate heater if desired.

"ELECTRONIC LIVESTOCK WATERING DEVICE"
BACKGROUND OF THE INVENTION
This invention relates to new and useful improvements in stock watering devices, particularly automatic water level control devices incorporating a heater to prevent freeze up during the cold weather.
Conventional stock watering devices are usually relatively large and include an immersion heater which is thermostatically controlled by a bimetallic strip type thermostat. Water flow is usually controlled by a conventional float and valve mechanism situated within the tank and covered by a domed cover so that it cannot be damaged by cattle or the like drinking from the tank or trough.
Many such watering devices draw the water supply from ether ground water storage means or a relatively shallow well, the majority of which often contain a high mineral con-tent which causes corrosion and/or mineral build-up on the many moving parts so that constant maintenance and/or replacement ox parts is often required.
Furthermore the immersion heaters normally used, are provided with a bimetallic strip type thermos ~;24~Z~;~
stat which often becomes inoperative so that the hatreds not disconnect when the predetermined temperature is reached thus leading to element burn out and subsequent freezing of the water in cold weather. This means that the operation of the devices must be checked constantly because of the multiplicity of working parts and the possibility of element burn out occurring.
SUMMARY OF THE INVENTION
The present invention overcomes all of these disadvantages inherent with conventional stock watering devices by providing a relatively shallow pan containing drinking water for cattle or the like in which firstly the heating element is bonded to the underside of the pan so that it is not in contact with the water. Secondly an electronic thermostat is included in which the temper-azure is controlled electronically inasmuch as it open-ales by changing temperatures into voltages and vice versa in order to control the temperature of the heater.
A further thermostat provides automatic heater shut down if there is no water in the tank, thus prevent-in the heater from overheating and burning out.
Thirdly, the pan is situated within an insult axed enclosure which includes a lower portion of acting as a control enclosure also insulated and being provided I
with a separate heater so that the interior is maintained at a predetermined workable temperature. The water inlet is connected to the base of the pan and an electronically controlled solenoid valve opens and closes the water inlet in response to a water level sensor in the wall of the tank which indicates when the tank level has dropped to a predetermined level thus opening the valve and which indicates when the water level has risen sufficiently thus closing off the valve. A time delay is included in order to prevent rapid cycling of the solenoid valve.
Other advantages are included in the device as will hereinafter become apparent and it should be noted that the tank is preferably formed from stainless steel to prevent corrosion such as rust or the like from occur-ring.
In accordance with the invention there is provided a livestock watering device comprising in combination an open topped pan for containing water, an insulated enclosure surrounding said pan and extending below the base thereof to define a control enclosure there below, an electronic control assembly in said en-closure connectable to a source of electrical power, a water inlet in said pan and entering said control en-closure and connectable to a source of water, a solenoid valve operatively connected to said electronic control assembly and said water inlet for controlling the flow of water to said pan, a water level sensor in said pan operatively connected to said electronic control asset-by, a heater panel bonded to the underside of said pan and being operatively connected to said electronic con-trot assembly, an electronic temperature sensor in said heating panel also operatively connected to said elect ironic control assembly for controlling the operation of said heating panel and hence the temperature of the water in said pan, and further heating means in said control enclosure operatively connected to said electronic con-trot assembly for maintaining a predetermined temperature within said enclosure.
Another advantage of the invention is to provide a device of the character here within described which is simple in construction, economical and opera-tonal and otherwise well suited to the purpose for which it is designed.

DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, reference should first be made to Figure 1 in which 10 illustrates the outer enclosure including a pair of spaced and parallel sidewalls 11 and a pair of spaced and parallel end walls 12 welded or otherwise secured together by conventional means.
The lower edges of the side and end panels are preferably interned to form flanges 13 for stiffening purposes, it being understood that the base of the enclosure is open as is the upper end.
The rectangular cover panel 14 is provided with a rectangular aperture 15 formed centrally therein and downtrend edges 16 which engage over the upper edges of the side and end panels 11 and 12 of the enclosure, it being understood that the cover is detachably secured to the enclosure by means of metal screws 17 or other similar fastening means.
An open topped pan 18 is provided having side walls 19, and end walls 20 together with a base 21 form-in the pan. The upper edges of the side and end walls L24~
are out turned to form lips 22 so that when the pan is dropped into the aperture 15 in the cover 14, the lips engage the upper surface of the cover immediately adja-cent the aperture 15 thus supporting the pan in position as illustrated in Figures 1 and 2.
Angulated brackets 23 are secured adjacent the corners of the enclosure 10 and act to secure the asset-by to a base 24 thus preventing inadvertent movement of the assembly during use.
Insulation, preferably of a solid or rigid type, is indicated by reference character 25 and is secured to the side and end walls if and 12 of the enclosure, by adhesive thus assisting in insulating the walls of the pan 18 and also the portion of the enclosure between the base of the pan and the lower ends of the enclosure which defines a control enclosure collectively designated 26.
An inlet 27 is provided within the base of the pan 18 adjacent one end wall thereof and this is connect-Ed to a conduit 28 extending downwardly into the control enclosure 26 and incorporating an electronically con-trolled solenoid valve 29 also within the enclosure 26.
The conduit then extends as indicated by reference char-cater 30, to a source of water (not illustrated), it ~L2~1~242, being understood that the conduit 30, externally of the enclosure 26, should be insulated so that freeze up does not occur.
A drain conduit 31 is provided within the base of the pan 18 adjacent the other end wall and this extends to an external discharge 32 within one end wall 12 of the enclosure, controlled by a valve 33 for drain-age and clean out purposes.
In this connection, reference should be made to Figure 1 in which an access door 34 is provided within one side wall 11 of the enclosure extending over most of the area of the panel and being hinged by hinge 35 adjacent one vertical edge thereof. A conventional catch or fastener 36 maintains the access door 34 normally in a closed position but allows it to be swung openly so that access can be made to the control enclosure when desire Ed Reference character 37 illustrates a rocketing-ular heating panel bonded to the underside surface of the base 21 of the pan. This blanket becomes an integral part of the stainless steel tank bonded to almost the entire undersurface thereof and of course is not in contact with the water within the pan 18.
The outside of the enclosure 10 is preferably 24~
painted black so that solar heating may assist in main-twining the temperature within the enclosure and the control enclosure 26 is provided with an additional heat-or 34 taking the form of a heater similar to an interior car warmer and being thermostatically controlled in a conventional manner.
An electronic control assembly 35 it provided within the control enclosure and connected to a source of electrical energy in a conventional manner. The heater panel 37 it provided with an electronic thermostat open-actively connected to the assembly 35 and operates on changing temperatures into voltages and vice versa in order to control the temperature of the heater and hence the water within the pan.
An additional thermostat is provided which operates if the pan runs dry and the temperature of the heater panel 37 reaches a predetermined maximum and this is also connected to the assembly 35 and shuts down the electrical power to the heater if this should occur.
The solenoid 29 is also operatively connected to the assembly 35 and is controlled by electronic sensors 38 in one wall of the pan 18 spaced downwardly from the upper edge thereof. These are actuated by the water in the pan and a time delay is in circuit so that the solenoid valve does not cycle on an off too rapid-lye .
In operation, the source of electrical energy is connected to a power box operatively connected to the electronic control module or assembly 35. Here the water line 30 is connected to the solenoid valve 29 and the control module or assembly 35 is of course already con-netted to the heater 37, the thermostat connected there-to, the solenoid 20 and the water level sensors 38.
When first turned on, the sensors indicate to the control module or assembly 35 a low or no water situation. The control module then opens solenoid 29 to allow water to flow into the pan. When the water reaches the sensors 38, a circuit is completed which closes a solenoid and shuts off the flow of water.
s an animal drinks from the pan, thereby removing water from the pan, the water level goes down.
After a predetermined delay, the sensor opens the solo-nod to allow water to continue to flow and replace the amount of water taken by the animal. When the animal ceases drinking, the water continues to flow until the level reaches the sensors 38 thus shutting off the solo-nod 29.
When the temperature is below freezing, the I
electronic temperature control will bring the heater to its preset temperature thus preventing freezing of the water within the pan.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.

An additional thermostat is provided which operates if the pan runs dry and the temperature of the heater panel 37 reaches a predetermined maximum and this is also connected to the assembly 35 and shuts down the electrical power to the heater if this should occur.
The solenoid 29 is also operatively connected to the assembly 35 and is controlled by electronic sensors 38 in one wall of the pan 18 spaced downwardly from the upper edge thereof. These are actuated by the water in the pan and a time delay is in circuit so that the solenoid valve does not cycle on an off too rapid-lye .
