Abstract: A hand tool with a U-shaped cutout to slide into the groove at the top of a champagne bottle, and pivoted lever-arms above the cutout straddling the stopper of the bottle. Extractor links connected to these lever-arms, are hinged at the outer end, and have teeth across the inner end, which is aligned with the stopper. Squeezing the lever-arms together causes the extractor links to engage and compress that part of the stopper exposed above the top of the bottle. The extractor links are angled upward toward the toothed end, so that the resulting combined upward force of the two links on opposite sides of the stopper, cause it to be extruded upward. Repeated actuations may be used to remove the stopper completely. The tool grips, and retains the stopper when completely closed.

Abstract: A reciprocating (saber) saw blade having normal cutting teeth for most of its working length from the tip towards the connection end.

Abstract: A spot sprinkler with means to clamp on and connect into the side of a soft hose, such as a “soaker” hose. Snap on diverter attachments are capable of generating and directing a spray pattern to plants in any direction from the sprayer connection. The sprayer has a small straight orifice directly accessible for any clean out that may be required. Installation or relocation of the sprinklers is accomplished without use of any tool. Flow ratings for each size of spot sprinkler enable calculation of water directed to individual plantings. By accurate measurable spraying, overall water use can be reduced. The few small, simple parts are inexpensive to produce. A prime objective of this uncomplicated invention is to foster use by the average homeowner.

Abstract: A pair of bearing support members (48, 50) are located within opposite end portions (12, 14) of an elongated housing (10). Piston drive rings (58, 68) are mounted for rotation on oblique inner end portions of the bearing support members (48, 50). A cylinder block (44) is mounted for rotation within the housing (10) between the bearing support members (48, 50). The cylinder block (44) includes a plurality of axial bores (46). A pair of pistons (70, 72) reciprocate within each bore (46). Each piston (70, 72) is connected to the piston drive ring (58, 68) at its end of the housing (10) by means of a connector rod (74, 76). An inlet scroll (206 or 208) and an outlet scroll (206 or 208) communicate with center regions of the cylinder bores (46).
