Abstract: A self-priming drain guard siphon insertable into the opening of any reservoir drain subjected to accumulation of fluid transported debris comprising an outer shell (17) enclosing an inner priming chamber (20) held upright on the bottom of a reservoir by support tabs (18). Priming chamber (20) is comprised of inlet openings (22), a horizontal chamber (20a), a vertical chamber (20b), and an outlet opening (24). Inlet openings (22) are each positioned above and between adjacent support tabs (18) and vertical chamber (20b) at an elevation slightly higher than the bottom of a reservoir. Inlet openings (22) are cumulatively sized to approximate flow capacity of horizontal chamber (20a) and are positioned on the underside of horizontal chamber 20a to prevent lateral passage and direct contact with median sized debris. Horizontal chamber 20a is sized to approximate the flow capacity of vertical chamber 20b.

Abstract: An oarlock comprising a base, a front leg extending upward therefrom and having a rearwardly extending top portion, and a rear leg extending upward from the base and having a forwardly extending top portion. The top portion of the rear leg is spaced from the top portion of the front leg and projects above and forward of a top end of the front leg. The legs form a ring for holding an oar, and the top portions of the legs form an opening for passing the oar into and out of the interior of the ring.
