Description

Patented June 17, 1930 NT orrics oc'ravn BERNARD GEEK, or wrnnouengsv, onro AUTOMATIC LIQUID FEEDER Application filed February 5, 1927. Serial No. 186,148.

r This invention relates to means for controlling the supply of water, or liquid feed to fowls, cattle and live stock generally.

he invention has as its primary object to maintain water at a predetermined level in a receptacle, the supply being automatically regulated by any change in the weight due to a variation in the level of the liquid, a lowering of the level of the liquid resulting in the opening of a valve to admit a supply and a raising of the level causing the valve to close and'cut off the supply.

While the drawings illustrate a preferred embodiment of the invention, it is to be 'un derstood that in adapting the means tomeet specific needs and requirements the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof;

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawing hereto attached, in which,

Figure 1 is a perspective view of an automatic liquid feeder embodying the invention.

Figure :2 is an enlarged sectional view of the valve casing, showing the .valve and a portion of the feed pipe.

Corresponding and like parts are referred to in the following description and designated in both views of the drawings by like reference characters. 7

For convenience of illustration supporting means is shown and includes an upright 1, and a base 2. The numeral 3 designates afeed pipe and 4 the casing of the valve mechanism whereby the supply is automatically con trolled. A platform 5 is hingedly connected,

to the base 2 so as to move vertically at its free end. A suitable receptacle 6 is mounted upon the platform 5 to move vertically therewith and is disposed beneath the regulating valve and in line therewith-to receive the '1 liquid discharged therefrom. A rod 7 extends upwardly from the receptacle 6 and is connected to the outer end of the horizontally disposed lever 8 pivoted intermediate its .5 ends to the valve casing 4. The inner end of the lever 8 extends upwardly, as indicated at 9, and is in contact with the head 10 at the lower end of a valve 11. A side portion of the casing 4 has a slot 12 formed therein to .55 receive the lever 8, whereby to maintain the said lever in given position. The pivot 13 upon which the lever 8 is mounted is support-- ed in the casing 1 at opposite sidesof the slot 12. A partition 14 is provided within the upper portion of the casing 41- and is centrally apertured, as indicated at 15, to receive the conical end of the valve 11. The lower portion of the opening 15 is enlarged to provide a seat to receive the conical end of the valve 11. An L open coil spring 16 surrounds the valve 11 and is confined between thepartition 14 and the head 10 and normally exerts a downward pressure tending to unseat the valve 11 and Y depress the inner end of the lever 8 and eles vate the receptacle 6. When the valve 11 is unseat-ed liquid fromv the feed pipe 3 flows through the valve casing 4 and discharges into the receptacle 6. When the level of the 7 liquid in the receptacle 6 reaches a predetermined point, the receptacle 6 is depressed and effects a closing of the valve 11 against the tension of the spring 16 and when the level of the liquid in the receptacle 6 lowers the spring 16 comes into play and effects an unseating of the valve 11 and a lifting of the receptacle 6, thereby permitting the liquid to flow from the feed pipe through the valve into thereceptacle which, when depressed by the supply of liquid thereto, effects a closing of the valve 11 and a cutting off of the discharge of the liquid as will be readily understood. to

Having thus described the invention, I

claim:

An automatic liquid feeder of the character specified including a valve casing having an inner partition formed with a central opening, and having a slot in a side, avalve within the casing having its upper end adapted to close the opening in the partition thereof, and having a head at its lower end, an 7 open coil spring mounted upon the valve and confined between its head and the partition of the casing, and a lever pivoted to the casing and extending through the slot formed in the side thereof, and having its inner end engag ing the head of the valve.

In testimony whereof I afiix inv signature.

OCTAVE BERNARD GEER. [11. s]
