COMBINATION FIRE HYDRANT.
The accompanying engraving illustrates a new improved fire hydrant, designed and built by the Coulter & McKenzie Machine Company, of Bridgeport, Conn The improvement consists in combining the gate-valve with the hydrant-casing, dispensing with the street gate-valve and valve-box, as used heretofore, and very convenient in case of repairs as by simply raising the frost case cover and inserting a lever through the gate-rod into the rack teeth, the gate is worked up or down very easily. After shutting the water off, remove the three nuts, and the hydrant body can be taken out with valve, etc., without distuibing the other parts. The wedge gate-valve is held firmly to its seat by wedge-shaped ribs cast on inside of the base, in such a manner that the ways cannot be obstructed by dirt, etc. The top or dome of hydrant is cast solid to the body, and has a stuffing box, fitted with a metal ring packing of a special form, easy to adjust, and will never need renewing. By turning the gland-nut it tightens the ring pack ing, and makes a perfect water-tight joint. The brass ring valve for drip (just above the rubber), is arranged so as to be open when the hydrant valve is closed, and drip closed when hydrant is open and has two positive clear water-ways of 5-8inch diameter each *ith no springs or light parts to rust or fill up. All hydrants are made of the best materials and tested in the most thorough manner, each piece being made to guage insures interchange, so that a duplicate part may be ordered by the letter designating the same. The same hydraut is also made without the gate-attachment, if desired.
