Abstract: A bulldozer blade pitch adjuster is disclosed having an adjustable length member with a body and two threaded members threaded into opposing ends of the body, and a cover that can be attached to the body to cover the body and the two threaded members, that can be removed from the body and engaged with the body in a second adjusting position where the cover acts as a wrench to rotate the body, thereby changing the length of the adjustable length member. Once the member is adjusted, the cover can be secured to the body in its first covering position.

Abstract: The mortar cap receives cementitious materials therewithin, such as cement, mortar, and the like, to define a footing for a catch basin grating, and has a base frame with parallel, spaced-apart walls, and an ancillary frame also with parallel, spaced-apart wall. The base frame is set within the ancillary frame, and the latter is slidably and vertically displaceable relative to the base frame. The ancillary frame has a plurality of knobs projecting from wall surfaces thereof which confront given w=all surfaces of the main frame, and the given wall surfaces of the main frame has a plurality of racks of ribs. With vertical displacement of the ancillary frame, relative to the main frame, the knobs engage the ribs and, as a consequence, the ancillary frame is arrestingly held in the displacement.

Abstract: The mortar cap receives cementitious materials therewithin, such as cement, mortar, and the like, to define a footing for a manhole frame, and has a base frame with a pair of concentric, spaced-apart walls, and an ancillary frame, also with a pair of concentric, spaced-apart walls. The base frame is set within the ancillary frame, and the latter is slidably and vertically displaceable relative to the base frame. The ancillary frame has a plurality of knobs projecting from walls thereof which confront given walls of the base frame, and the given walls of the base frame has a plurality of racks of ribs which confront the knobs. With vertical displacement of the ancillary frame, or a sector of the ancillary frame, the latter is arrestingly held in the displacement due to an interference of the knobs and ribs, and an engagement of the knobs with a pair of the ribs.
