Among his latest inventions is the Freezeless Hydrant. This innovative hydrant features an operating screw positioned within a head member, along with an operating coupling that mates with the operating screw. The design includes an operating rod coupled to the operating coupling, a plug, and a valve seat. The movement of the operating rod in one direction disengages the plug from the valve seat, allowing water to flow through the casing. Conversely, moving the operating rod in the opposite direction aligns a radial opening in the operating coupling with a passageway in the operating screw, preventing water flow and allowing air to drain water from the chamber.
Another significant invention is the Hydrant Box. This wall hydrant box features a unitary front plate that is welded onto the front portion of the box. The front plate is designed to accommodate a ring or similar structure, which remains obscured when viewed from the front. This design not only enhances functionality but also provides a uniform and aesthetic appearance to the hydrant box.
