ABSTRACT:
A hand-held water injecting tool (10) provides for the admixture of water to cementitious materials. The tool (10) is generally comprised of a water-conveying tubular body (12), and a blade assembly (16) having a tip (17). The tubular body (12) has a circuitous configuration to afford both a built-in, ergonomic handle portion (35) and a capacity to perform mixing operations within relatively high-walled containers. At a water-emitting end (20) are present a pair of nozzles (52) which are integrally fashioned from the tubular body (12) to impart jet action to the emitted water. The blade assembly (16) includes a generally triangularly shaped blade (62) attached to the second end (20) such that the water is emitted from the nozzles (52) at a location proximate and external to the blade tip (17) so that the force of the fluid is used in close conjunction with mechanical action of the blade. An alternative embodiment (710) provides a second end (720) adapted to receive a tang (82) of a blade (762) having an arrow-like or "winged" appearance. Channels (86) upon either side of the tang (82) function as nozzles (752) which are shielded from an influx of solid particles by the thickness of the blade (762) to afford an anti-clogging capability. A second alternative embodiment (810) provides a check valve system constituted by a blade (862) having a depressed portion (88) within which the second end (820) lies and a flap (90) which covers the second end (820) and depressed portion (88).
