Abstract: An impact sprinkler has a nozzle connected to a housing and a discharge deflector member connected to a rotatable shaft assembly. The sprinkler has different replaceable nozzles and discharge deflectors for providing desired discharge characteristics. The shaft assembly and housing have contacting braking surfaces outside of the water flow providing a frictional braking force dependent on both water flow rate and pressure. The sprinkler has a deflection member for rotating an impact assembly relative to the shaft assembly while a pin supports the impact assembly at a position above the deflection member. A lower portion of the shaft assembly may be positioned in a recess in the housing such that a surface on the shaft assembly contacts a surface in the recess, and a highly wear-resistant material may be disposed on a surface of either the shaft assembly or the recess for providing improved wear characteristics.

Abstract: A rotary impact sprinkler is disclosed having a nozzle connected to a housing and a discharge deflector member connected to a rotatable shaft assembly without a dynamic seal between the nozzle and the deflector. The sprinkler may be provided with different nozzles and discharge deflectors that are easily removed and replaced for providing desired water flow and discharge characteristics. The shaft assembly and housing may have contacting braking surfaces outside of the water flow. The braking surfaces may provide a frictional braking force dependent on both water flow rate and water flow pressure. The sprinkler has a rotatable impact assembly supported by the shaft assembly and including a deflection member for rotating the impact assembly relative to the shaft assembly. The shaft assembly may have a pin for supporting the impact assembly at a position above the deflection member.

Abstract: A novel drill bit adapter includes a body portion, a cap portion, a spring-biased catch and a push button actuator. The cap portion includes a transverse aperture and cooperates with the body to define a longitudinal aperture and a catch-receiving cavity. The push button is disposed in the transverse aperture and engages the catch to move the catch in the cavity relative to the longitudinal aperture in opposition to a biasing force supplied by the spring. The spring is a wire spring that extends longitudinally from the body portion into the cap portion to engage the catch.

Abstract: An installation jig includes a pair of jaws and a latch guide coupled together by an adjusting mechanism. The jig includes a pair of backset spacers mounted to the latch guide rotational movement between a first backset position and a second backset position. A detent mechanism maintains each backset spacer in a selected backset position and, when combined with the rotational movement, provides a tool-free backset operation. The jig also includes a pair of removable in-line arms to provide the capability to perform a standard door prep on metal and wood doors. In addition, a novel drill bit adapter is disclosed.
