SPECIFICATION forming part of Letters Patent No. 551,027, dated December 10, 1895.

Application filedApril 12, 1893. Serial No. 470,074. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES A. BROWN, a citizen of the United States, residing at Sublette, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in Automatic Watering-Troughs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification. Y

My invention has reference to automatic watering-troughs; and it consists of an improvement on the construction for which on July 5, 1892, Letters Patent of the'United States No. 478,397 were granted to me.

The objection to the former method and to most if not all of the automatic wateringtroughs heretofore in use where the same are governed by a float has been .that. the float has not sufficient power to hold the exit-valve with the necessary force against the outlet end of the water pipe, particularly where there is considerable head in the vessel from which the water is drawn, unless the float be made of such size as to be inconvenient and to require a very large Valve-box.

In my invention the purpose is to so arrange the fulerum-point of the float-lever in reference to the opening under the valve and the pivotal connection of said lever with the valve that the three aforesaid points-to wit, the opening covered by the valve, the pivotal connection of the valve to the adjacent end of the float-lever, and the fulcrum of the said levershall be in a line when the valve is seated, whereby the short end of the floatlever acts as a lock and is held in position against the pressure of the water by a very slight supporting-float at the longer end of said lever.

My invention also comprises a nut having a tapering lateral elongation or sleeve adapted to encircle the end of the supply-pipe which projects into the supply-tank and to be forced into the opening in the latter around said pipe, and thereby seal said opening outside of said pipe so tightly as to prevent the usual dripping of water occasioned by the pressure in the supply-tank.

My invention also comprises the placing of a hood over the inlet end of the supply-tube within the supply-tank, such hood having the inlet-opening 3 in its lower end and having its inner side oblique, whereby the water rising over the lower end of said hood forces the material floating on the surface of the water away from said inlet, and also when the water lowers from an altitude above the said hood said inclined side tends to force the floating material away from the bottom of the hood.

I obtain these advantages by the construction shown in the accompanying drawings, in which- Figure 1 is a side elevation of the operative portions, the supply tank or reservoir, valvechamber, and drinking-trough being cut away for the purpose of exposing the interior. Fig. 2 is a detail of the sealing-nut before referred to.

A is the usual supply-tank or water-reservoir from which it is intended to draw the water. B is the valve-chamber, communicating with the supply-tank by means of a tube 0, of sufficient length to extend slightly through the adjacent walls of said chamber and tank.

D is the drinking-trough,formed against the valve-chamber B and communicating therewith through the inlet E at the bottom of the partition between B and D.

The end of the tube 0 which projects within the tank A is threaded to receive a nut F, integral with which is formed the tapering sleeve G, adapted at its outer and smaller end to project into the opening 1, through which the tube 0 enters the tank A, and in tightening the nut F the sleeve G is wedged into said opening, thereby preventing the escape of the water through the same around the tube 0.

H is an ordinary nut seated on the tube 0 outside of the tank A to receive the drawing action of the nut F. A wedge-shaped washer 2 is interposed between the nut H and the flaring side of the tank A. V

J is a hood having a hollow interior suitably seated on and communicating with the inlet end of the tube 0 and having also a water-inlet 3 at its lower end. The side of the hood J opposite the pipe 0 is formed of two angular sides at and 5, the latter projecting diagonally upward toward the center of the tank and the side 4 projecting diagonally upward from said center.

The tube G is threaded a short distance outside of the chamber 13, and a nut 6, seated on said tube, with an interposed washer 7, seals the opening into the valve-chamber. Around the exit of the tube 0 within the valve-chamber there is seated against the wall of the latter a plate 8, to whieh'is rigidly fixed the lower end of the standard f),whieh is turned upward into the horizontal plane of the outlet of the tube C to serve as a fulcrum for the valve-lever K, and to the outer end of the lever is pivotally attached the float L.

\Vithin the standard 9 and against the outer end 10 of the pipe 0 there is located the valve M, to the inner side of which there are centrally attached short horizontal ears N, to which the adjacent end of the lever K is pivoted at 11. The lever K is fulcrumed at the upper end 12 of the standard 9 in the horizontal plane of the pipe end 10 and the valvepivot 11 when said valve is closed, in which position the lever K is substantiallyhorizontal. \Vhenever the water is of sufficient height in the valve-cha1nber to carry the valve-lever K into a horizontal position it will be seen that the points 10, 11, and 12 are in the same horizontal line, when the outward pressure of the water through the tube 0 being in the line of the pivot 11 and fulcrum-point 12, but a slight lifting action of the float L is necessary to keep the valve M seated.

As the float L descends with the depletion of the water the lower end of the valve M is turned away from the exit 10, permitting the water to escape into the valve-chamber until such time as the lever K is again carried by the float L into a horizontal position.

P is a half-spherical hood seated on plate 8 and serving to cover the valve M. A spring R, coiled on the fulcrum 12, has its one end 13 bearing against standard 9 and the other end 14 under lever K to assist the float L in rising.

I find by experience that springR is of great advantage in the combination to which it contributes, as it helps the float L to seat the valve M against the water-pressure in reservoirA, wherebyI can use a smaller float and a smaller chamber for it. The weight of the lever and pressure of the water will open the valve against the spring.

hat I claim as my invention, and desire to secure by Letters Patent of the United States, is

The combination of the reservoir A, pro vided with opening 1, tube 0, projected, from the outside, a short distance within said reservoir, nut II, seated on said tube, outside of and against said reservoir, nut F, provided with tapering sleeve G, seated on said tube within said reservoir, with said sleeve projected into opening 1 around said tube, and the hood J, seated on the inner extremity of said tube and provided at its lower end with inlet 3 and with the interior angular sides E and 5, substantially as shown and for the purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.
