摘要： A sleeve-encased cartridge-type, unidirectional-flow, gear pump for compressors and the like having circumferentially aligned inlet openings in a stationary sleeve wall adjacent a covered end portion of the cavity thereof, and within said end portion an indexible flow connector block rotatably supported for turning to opposite limits of movement on a fixed concentric support. The block is resiliently urged against the end faces of an internal spur gear pump housed in the opposite end portion of the sleeve cavity, the inner gear of said pump being mounted on a pinion having a stationary axis offset from the sleeve axis and projecting from the end of said concentric block support, and the outer ring gear being rotatably supported by the sleeve wall. A drive connector plate engageable on the end of a compressor input shaft has a driving engagement to rotate the outer ring gear. The connector also has sealed passage means for joining an axial lubrication bore of an input shaft with a pump outlet bore in the offset pinion and the block support. One of a pair of radially directed passages in the support is connected to said outlet bore and the pump outlet side by an angled outlet passage of the indexible block at opposite limits of movement. An angled inlet passage in the block correspondingly connects the low pressure inlet side of the pump with an opening of the stationary sleeve wall.

摘要： A tool for applying, forming, and twisting a wire-tie at rod cross-over points of concrete reinforcement grids and the like, having releasable jaw clamping means to grip intersecting rods together at right angles, wire feeding means to direct the legs of a pre-formed hair-pin like looped wire onto anvil surfaces in said clamping jaws and engage the looped end thereof against one of the rods while said legs are being reversely turned around the other rod with the free ends thereof straddling said first rod, and means for twisting said free ends together. The wire-tie so fastened is characterized by opposed pairs of spaced loops embracing the rods, the loops of the pair about each rod lying in a parallel planar relation to each other and in perpendicular planar relation to the plane of each loop about the other rod. The tool, by sequentially operating actuator means, clamps the jaws, feeds and forms the legs of the preformed wire, twists the free ends, and then releases the jaws in a single reciprocating stroke.
