Abstract: Odor control product dispenser includes a cabinet having a removable front cover for directly accessing both an upper fan compartment and a lower product compartment from the front. A fan in the fan compartment draws air in through a fan shroud surrounding the fan and directs the air downwardly into the product compartment for flow across an exposed surface of the odor control product in the second compartment and subsequent discharge through air vents in the front and sides of the cabinet. The odor control product is contained in a well in one end of a disposable container. Within the well are a plurality of circumferentially spaced pinwheel type baffles that increase the turbulence of the air flowing across the product as the product evaporates to accelerate the rate of evaporation as the product loses its potency (effectiveness) with age.

Abstract: A voltage regulator powered by an electrical power source having a discharging voltage characteristic and regulating the voltage applied to an electrical load from the power source includes a stable reference voltage source, a sensor for sensing the voltage applied to the load, an error signal generator for generating an error signal related to the difference between the sensed and reference voltages, and a voltage control connected in series with the electrical load and responding to the error signal to control the voltage applied to the load as the power source discharges. The invention is particularly useful when the power source is a single cell battery and the load is a direct current motor. Embodiments of the invention may apply a substantially constant or an increasing voltage to a load as the source voltage declines according to its discharge characteristic.

Abstract: A flexible duster head holder includes a stiffener over which a conventional duster head is placed. The stiffener may be bent to conform to the shape of a non-flat surface to be dusted. The stiffener consists of a bendable metal wire core which is sufficiently rigid to hold the shape to which it is bent until being bent to a different shape. Surrounding the core is a resilient vinyl sheath or cover which limits the sharpness of any bend that can be imparted to the stiffener, thereby reducing the likelihood that the wire core will break. Two different methods are described for attaching the stiffener to a clamp assembly.

Abstract: Dust mop frame includes a plastic molded base member having a substantially flat bottom surface for applying uniform pressure over substantially the entire surface of the dust mop and a rigid hinge member securely molded in place in spaced relation to the back side of the base member to facilitate attachment of a handle to the dust mop frame. The hinge member is supported adjacent its ends by a pair of laterally spaced, transversely extending ribs integrally molded to the back side of the base member. The ends of the hinge member extend completely through the transverse ribs into a pair of longitudinally extending ribs integral with the axial outer sides of the transverse ribs intermediate the ends thereof and also integral with a peripheral rib around the outer edge of the base member.

Abstract: Pad holder includes a generally flat rectangular mounting plate or head having a front or bottom side to which the pad is attached and a top or back side having a plurality of spaced-apart ribs thereon terminating in a common plane substantially parallel to the planar bottom side of the mounting plate to provide for the transfer of pressure from the wringer plates of a conventional mop wringer to the pad through the ribs to squeeze out the pad. The ribs provide for the recess mounting of a hinge member to the back side of the mounting plate. The hinge member permits a handle socket connected thereto to be pivoted up against the back side of the mounting plate below the tops of the ribs where it will not interfere with the pressure engagement of the wringer plates with the ribs and pad, respectively, during wringing out of the pad.

Abstract: Mop swab includes a threaded center stud supported by a support strip which extends transversely of the mop head and has mop cords covering both the side edges and ends of the support strip. The center stud is located in the approximate center of the length of the support strip, and the ends of the support strip extend in opposite directions beyond the center stud for a substantial portion of the width of the mop head to provide adequate support therefor. The support strip is secured in place intermediate the mop cords by a tape headband which is wrapped around the mop cords and support strip therebetween and stitched to the mop cords by a plurality of rows of stitching extending entirely through the headband and mop cords adjacent the opposite side edges and ends of the support strip.

Abstract: Mop holder includes a main frame portion having a loading bar cantilevered at one end to the main frame portion and a hinged side gate at the other end which can be lifted up to permit a mop swab to be slid on or off the loading bar at such other end. A clamping bar movable toward and away from the loading bar releasably clamps the mop swab tightly against the loading bar.

Abstract: Handle includes a main handle portion and an outer end portion pivotally connected thereto. Both the main handle portion and outer end portion have connecting members extending from the adjacent ends thereof, with offset flanges thereon in overlapping engagement with each other and connected together by a bolt and nut arrangement. The opposed faces of such offset flanges have radially extending teeth in mating engagement with each other positively to retain the outer end portion in any desired adjusted position from straight out in line with the main handle portion to approximately 90.degree. in either direction or anywhere in between upon loosening and retightening the nut.

Abstract: A bowl mop for use in cleaning toilet bowls and the like including a disposable yarn head having a slide portion slidably received in a slot on a projecting end portion of a handle. The slide is releasably retained within the slot as by engagement of a cam projection on the slide in a recess in the handle end portion to permit the disposable yarn head to be snapped off for easy disposal and replaced with a replacement head. The handle end portion extends at an angle relative to the longitudinal axis of the handle to facilitate cleaning of difficult to reach areas. Also, the handle is adjustable to different lengths for safer, faster cleaning with less bending and stooping and less operator fatigue.

Abstract: A handle attachment device for easily attaching a handle to a dust mop or the like including a clip that is readily secured to or removed from the frame of the dust mop and a connector member for coupling the clip to the handle. The clip includes only a pair of relatively movable members that capture the shaft of the dust mop frame therein, and such clip may be released for swiveling movement relative to said connector or locked in place as desired.

Abstract: The backing for the mop has oppositely facing pockets at each end, one of which is much shorter than the other and has a cross member overlying the open inner end thereof. The cross member is secured to the backing along opposite edges thereof and is open at both ends thus permitting one end of a slip-through frame to be inserted through the cross member from the outer end thereof and into the larger pocket at the other end of the backing. The other end of the frame is then inserted into the shorter pocket by pulling the shorter pocket back from underneath the cross member and over the other end of the frame. The innermost ends of the cross member and larger pocket are spaced apart a sufficient distance to permit the folded ends of a breakdown frame to be inserted therein.

Abstract: A duster head characterized by a central sleeve portion made from a strip of open mesh backing material, and a plurality of spaced apart longitudinally extending rows of yarn fringe material stitched thereto. To make the duster head, initially two inside rows of the fringe material are stitched to one side of a flat strip of the mesh backing in spaced relation from each other and from the edges of the backing before the backing is formed into the desired cylindrical shape. Both inside rows may extend almost the entire length of the backing material, terminating a short distance from each end thereof. However, preferably one of the inside rows is continued to the adjacent side edge of the backing near the upper end thereof to ensure more complete coverage of the backing by the fringe material in that region. The bottom raw edge of the backing is then serged to give it added strength.

Abstract: Extension handle consists of a pair of telescoping handle parts made out of relatively thin-walled plastic tubing. A protrusion on the outer wall of the inner tubular member, formed as by inserting a pop rivet therethrough, frictionally engages the inner wall of the outer tubular member to provide some drag or resistance to axial movement of the tubular members relative to each other. The outer tubular member, being made of relatively thin-walled plastic tubing, will deform more or less according to the amount of interference between the rivet and inner wall of the outer tubular member. A rigid metal or plastic ring at the inner end of the outer tubular member acts as an abutment or stop for the protrusion on the inner tubular member thus preventing the telescoping handle parts from being completely pulled apart.
