Abstract

This invention consists of a vertically disposed steel or cast iron tubular member adapted to be bolted onto a support collar which in turn is secured by a key to a ball valve support flange that is bolted over an opening in a water main. The aforesaid tubular member is provided with both a plurality of horizontally disposed water outlets and a vertically disposed threaded rod whose upper end extends out of the top of the tubular member to terminate in the center of a hand wheel. The lower end of the aforesaid threaded rod is provided with a ball cup that presses down onto the top of a spring-loaded ball valve that is located in the lower end of the aforesaid ball valve support flange. The invention is adapted to be quickly removed from the top of the outlet of a water main at which time the water supply automatically will be shut off by the automatic action of the aforesaid spring-loaded ball valve.

Claims

1. A portable fire hydrant of the character described, comprising a vertically disposed tubular member having a pluraity of horizontally disposed water outlets extending outward therefrom;

a ball valve support flange, means including lugs for quickly connecting and disconnecting said tubular member to said ball valve support flange;

means for bolting said support flange to an opening in a water main;

the ball support flange having a central opening therethrough and a rim surrounding said opening and extending downward from said ball valve support flange, a separable cylindrical spring and ball valve cage whose upper end encompasses said rim, a spring and cage holder adapted to be located in the lower part of said water main and secured to the lower end of said cage and adapted to engage the adjacent water main wall to attain alignment of said cage and rim, a coiL spring in the lower end of said cage, a ball valve in the upper end of said cage and a ball valve holder interposed between the ball valve and the spring, said ball valve urged into seating engagement with said rim to arrest flow through said opening, and manual means for moving said ball valve to an open postition.

2. The invention of claim 1, wherein the said manual means of turning on the water in the said fire hydrant is by a vertically disposed threaded rod that has its upper end extending out of the top of the said tubular member to terminate in a hand wheel;

and the lower end of the said threaded rod being provided with a ball cup that presses down on top of the said ball valve when the water is to be turned on for the said hydrant.
