By placing the vent near 9o as shown at a, Fig. 2.

Secured upon the over and -away from the vent. Besides rerod G, beneath the cross-piece of the arch, ducing the weight and cost of the valve by and preferably by a set-screw c, so as to renthis construction, the friction was also reder it adjustable, is the waste-valve L, whose duced from that of a large circular band to 5o outer surface is recessed to receive a rubber only a mere fraction of it, and by arranging 100 the valve in a vertical line with the arch any lateral pressure upon the valve-rod by the Valve is taken up by the entire arch and a very secure support is obtained.

Still another advantagesecured by placing the waste-vent above the ring, instead of within it, is that the iiow of water is not checked to so great an extent as it would be if the valve came entirely down into the ring, and it alsol permits of a wider waste-valve being used, which can be so arranged that when the main Valve is seated the lower edge ofthe waste-valve is just above the vent. `In this position the Waste-vent is closed as soon as the main valve moves downward the distance of the diameter of the vent, which can be made very small, and it remains closed until the main valve returns to that point in closing, thus reducing the waste, while the main valve is open to the minimum, which is an important consideration in large cities, and especially during hot dry weather, when considerable water is being used. It also permits of the hydrant being used with less than a full head without letting water escape at the Vent all the time, which could not be done if the Ivent were placed within the ring, and by making the valve segmental instead of circular ythe obstruction to'the flow of the water through the hydrant is reduced to the very lowest point, which, with the other advantages, makes it a very eficient device in everyy respect.

Another change from the construction shown in our former patent consists in leaving a space. between the outer surface of the upright and the inner surface of the wall of the Waste-chamber to avoid the possibility of the uprights from engaging with any sediment which might be within the waste-chamber, and thus interfering with the free rotation of the ring and the arch in their removal;

` but this change necessitated the use of a tube Athe waste-chamber could not be closed by the waste-valve. With a tube inserted within the holes, however, a continuous passage from the interior of the valve-chamber to the outside of the 'waste-chamber is formed, andthe valve will close it in the same manner as was done heretofore.

Having thus fully described our invention, we claim- In ahydrant, the combination, with a wastechamber having a hole or waste-vent near its lower end, ,of a valve-ring in its lower end having an arch projecting up into the chamber, the outer faces ot' the uprights of which arch are at a distance from the inner face of the wall of the waste-chamber, and one of the uprights being also provided with a hole or waste-vent near its lower end above the ring, a tube removably secured within the said holes leading from the interior of the arch to the exterior of the Waste-chamber, a non-rotatable Valverod through the arch having a main valve on its lower end, and a segmental waste-valve on the rod within the arch, the outer face of which is vertically movable against the inner face of the upright having the waste-vent, substantially as described.
