June 10, 1930. L. K. WILSON SIPHON DEVICE FOR WATERING LIVE STOCK Filed March 9, 1926 wry/r01? Lew/ls M/Son Patented June 10, 1930 PATENT OFFICE LEWIS K. WILSON, OF PHILADELPHIA, PENNSYLVANIA SIPI-ION DEVICEIFOR WATERING LIVESTOCK Application filed March 9, 1926. Serial No, 93,359.

Objects of the present invention are to improve the siphon system of supplying fluid to live stock ;.to attainsimplicity and economy in manufacture; to automatically and positive sly open the feed pipes to replenish the cups and to. automatically close the feed pipes at other times, thus preventing any possible back siphoning and consequent drainage of the cups, and contamination of the balance of the system with slime, sediment or disease germs; to provide convenient means for permanently or temporarily shutting oil the siphon without removing the cups; and to provide a valve structure comparatively simple 15.,and inexpensive to manufacture and positive and reliable in use.

The invention. will be claimed at the end hereof but will be first described in connectionwith the embodiment of it chosen from among other embodiments for the sake of illustration in. the. accompanying drawing forming part hereof and in which Figure 1 is a sectional View.

Figure 2 is an end view looking toward the left in Figure 1, and

Figure 3 is a view similar toFigure l illustrating the position of the parts for shutting off the siphon.

In the drawing 1 is a siphon supply pipe. 2 is a support. 3 is a cup or receptacle carried by and movable on the support and into which one leg 4 of the pipe 1 dips. As shown the cup 3 is connected with the support 2 by means of clamps 5 which can be tightened or loosened by means of bolts and nuts 6. 7 is a guide cavity provided at the bottom of the cup and aligned with the open end 8 of the leg 4 of the pipe 1. 9 is a float shown as a buoyant spherical body and its movements are confined by said cavity for cooperation with the open end 8 of the leg 4 as a backtrap or valve. 10 is a plate seated in the cup above the open end 8 of the leg 4:. The plate 10 is perforated or otherwise formed or arranged to provide fluid ways or passages. 11

is a depending lug provided on the plate and positioned for additionally confining the movements of the float.

The float or body 9, being lighter than the liquid in which it is suspended, operates as a back trap or valve for the open end 8 of the pipe. The float or body 9 canbereadily inserted and removed by withdrawing the plate 10. The plate 10 prevents the animal from getting its mouth far enough into the cup to. drain the same suiliciently to break the siphon. The cavity 7 can be readily provided in the cup during its manufacture. Obviously the provisions for confining the movements of the heat or valve 9 are independent of the supply pipe and are of such construction that g the stock may not interfere with the proper operation of the valve and are such that they are simple and reliable. To permanently or temporarily shut off the siphon. thecup is raised on the support 2, and clamped in such position that the float or ball 9 closes the end 8 of the pipe as shown in Figure 3, so that water may not enter the cup,and when an animal has drained the cup it receives no more water which is often desirable in the case of sick animals. There is a fitting or union 12, interposed in the main pipe and it is provided with an outlet 13, to the siphon pipe and this outlet leads from the lower portion orbottom of the main pipe. Air in the fluid in the main pipe rises to the top thereof, so that by arranging the out-letat the lower part of the main pipe the passage of air from it through the siphon pipe inwhich itwould accumulate and tend to break the seal, is avoided.

Those skilled in theart understand that the Water supply to the pipe 12 is such that the water rises, as by gravity, in theleg 1 to a level below the inverted U-shaped portion, and the latter being filled and the cup also being filled to the desired level, which is identically the same as the level to which the water rises in the pipe 1, there is no flow. The lower end of the leg 4 dips into the waterin the cup 3 and is sealed thereby. When the level in the cupis loweredwater flows through the illverted U-shaped portion of the pipes by siphoniaetion.

It maybe remarked that when the water in the cup 3 is at normal level the float 9 seals the open end of the dip pipe,and thus prevents withdrawal thereof by the lowering ofthe level in anothereup of. the series of cups.

which are provided in such systems. It may also be stated in connection with the element 13 that the supply to the pipe 12 is not under suflicient pressure to prevent the water from carrying am It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement and in matters of mere form without departing from the spirit of the invention which is not limited to such matters or otherwise than the prior art and the appended claims may require.

I claim:

1. A siphon device for watering live stock comprising a siphon supply pipe, a support, a cup carried and movable on the support and into which one leg of the pipe dips, a guide cavity provided at the bottom of the cup and aligned with the open end of said pipe, a float confined by said cavity for cooperation with the open end of the pipe, a plate providing fluid ways and arranged in the cup above the open end of the pipe, and a lug provided on the plate and depending into position for gldditionally confining the movements of the oat. r

2. In a siphon device for watering live stock, a cup, a siphon supply pipe, of which the end is arranged for constant submergence in the contents of the cup, a float arranged at the bottom of the cup and adapted to normally close the end of the pipe, and a plate providing fluid ways and arranged above the float and above the open end of the pipe.

3. In a siphon device for watering live stock a cup, a siphon supply pipe dipping into the cup, a float cooperating with the end of the pipe, and a plate providing fluid ways and having a depending lug cooperating with the float.

4, In a siphon device for watering live stock a cup, a siphon supply pipe one end of which is arranged for constant submergence into the cup, a float, arranged at the bottom of the cup and adapted to normally close the end of the supply pipe, a plate spaced from the bottom of the cup, and provisions between the cup and plate for guiding the float.

5. In a siphon device for watering live stock a cup, a siphon pipe of which the end is arranged for constant submergence in the fluid in the cup, a body lighter than the liquid in which it is suspended and arranged at the bottom of the cup, and provisions independent of the supply pipe for directing the supply pipe for directing the movements of the said body in respect to the end of the pipe.

7. In a siphon device for watering live stock a cup, a siphon supply pipe of which the end is arranged for normal submergence in the contents of the cup, and a plate providing fluid ways and spaced from the bottom of the cup and arranged above the end of the pipe and adapted to prevent the consumption of liquid below the end of the pipe.
