WATER-GATE.

SYECIFICATION forming part Of Letters Patent No. 581,538, dated April 27, 1897.

Application filed May 25, 1896. Serial No. 592,928. (No model.)

To all whom it may concern.-

Be it known that I, JESSE T. DEAN, a citizen of the United States, residing at Clintonville, in the county of Coffee and State of Alabama, have invented certain new and useful Improvements in Water-Gates; 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 of reference marked thereon, which form a part of this specification.

This invention relates to water-gates.

The object of the invention is to provide a gate so constructed that water may automatically be maintained at a predetermined height in a flume or basin, which gate shall be simple and cheap in construction, not liable to get out of order, and which shall be reliable in operation.

With this object in view the invention consists of a gate pivotally mounted in suitable uprights, a lever mounted adjacent to the gate and having one end adapted to bear against the gate to retain the same in a closed position, a receptacle adapted to receive water and mounted on the opposite end of the lever, and a trough having its receiving end communicating with 'a flume or basin and having its discharge end over the receptacle on the lever.

Further, the invention consists of various novel detailsof construction and combination of parts whereby the object of the invention is accomplished and the effectiveness of the device is insured.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a gate constructed in accordance with my invention, one side of the frame of the gate being broken away, the parts being shown by full lines in the position assumed when the gate is closed and indotted lines in the position assumed when the gate is open; and Fig. 2 is a plan view of the gate.

In the drawings, A represents the gate, which is pivotally mounted on a rod 0;, having bearings in the frame B, in which the gate is placed. The point at which the gate is pivoted is preferably a distance from the bottom a bevel a at the top where the end of the lever 0 bears against it, and the end of the lever is correspondingly beveled at the end 0 Placed upon the lever 0 adjacent to the beveled end 0 is a weight 0 which is somewhat greater than the normal weight of that part of the lever on the opposite side of the pivot to that on which the weight is placed. The end of the lever opposite to that which bears against the gate is provided with a receptacle 0 having in the bottom thereof an opening 0 the receptacle being of such capacity that when filled with water the end of the lever carrying the receptacle will be heavier than that of the end which bears against the gate.

Adjacent to the gate and placed at a height at which it is desired to maintain the water in the flume or basin is a trough D. One end d of this trough communicates with the basin or flume and the other end d is arranged immediately above the receptacle 0 In the use of the gate the parts are normally set in the position shown by full lines in Fig. 1, and this position will by the described construction and arrangement of the parts be maintained until the water'in the fiume or basin rises to a pointjto flow through the troughD. When this takes place, the water flowing through the trough is discharged into the receptacle 0, and as soon as sufficient weight is imposed upon the end of the lever O, carrying the receptacle, to overbalance the weight 0 the beveled end of the lever is removed from the gate. The gate being mounted, as described, will be opened by the pressure of water and will remain open until the level of the water is but a short distance above the point 'at which the gate is pivoted. At this point theipressureion the lower portion of the gatejwill close it. When the water ceases flowing into the receptacle 0 the latter, being buoyant, Will discharge its load through the opening in its bottom, and when the receptacle is empty the Weight will return the lever to its initial position.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A Water-gate pivotally mounted in suitable uprights, a lever mounted adjacent to the gate and having one end adapted to bear against the gate to retain the same in a closed position, a receptacle adapted to receive Water and mounted on the opposite end of the lever, and a trough communicating with a flume or basin and having its discharge end arranged above the receptacle, substantially as described.

2. A gate pivotally mounted in suitable uprights, a lever mounted adjacent to the gate disconnected therefrom and adapted to bear against the gate to retain the same in a closed position, the lever being provided adjacent to its end adapted to bear against the gate, with a Weight, and the other end with a receptacle, and a trough having one end communicating with a basin or flume and having its other end arranged over the receptacle on the lever, substantially as described.

3. A gate pi votally mounted in suitable uprights and provided with a bevel at its upper end, a disconnected lever mounted adjacent to the gate and having one of its ends beveled and arranged adjacent to the bevel on the gate, a Weight arranged on the lever adjacent to the end bearing against the'gate, a receptacle arranged at the opposite end of the lever, the receptacle being buoyant and being provided in its bottom With an opening, and a trough communicating at one end with a basin or flume and having its other end arranged above the receptacle, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
