Abstract: A housefly deterrent device is an apparatus used to deter houseflies from approaching a particular area. The apparatus is also configured to mount to an appropriate area for ease of positioning and maintenance and does not rely on chemical compounds to affect houseflies. The apparatus includes a visual deterrent, an orienting fixture, and an attachment mechanism. The visual deterrent is a structure which mimics the physical appearance of the housing of various predators of houseflies sufficiently to affect the general behavior of houseflies. The orienting fixture is a mount which supports and arranges the visual deterrent in position, preferably adjacent to a door or a building entrance. The attachment mechanism is an arrangement of components that allows for connection of the orienting fixture to surfaces or relevant structures proximal to a target housefly protection zone. The visual deterrent is removable, facilitating adjustment, and general maintenance.

Abstract: An improved adjustable box wrench having a mouth (9) with a plurality of gripping surfaces (27, 31, 32) for surrounding a nut, bolt or the like. A movable jaw (5) allows the size of the mouth to be altered when a worm screws (8) is turned. The worm screw (8) has gear (24) which fit between teeth (20) in an arm (4) extending from the movable jaw (5). The adjustment arm (4) and worm screw (8) fit into cavities (14, 17) in the wrench body (1). Increased lateral support for the movable jaw is provided by at least one protrusion (19) on a side (21) of the jaw which fits into and moves longitudinally within at least one channel or groove (26) in fixed gripping surfaces (32) on opposite sides of the mouth (9). At least one removal slot (33) is provided to enable assembly and disassembly of the at least one protrusion (19) into the at least one channel or groove (26).
