Abstract:
An applicator (10) for particulate carpet-cleaning compositions having a cylindrical body (14) formed of relatively rotatable inner and outer concentric cylindrical members (18, 16) in 360 DEG frictional nested engagement, separately attached non-rotatably to opposite wheel members (34, 36) of greater diameter than the body, and having dispensing apertures (24) in one cylinder which may be closed by the other depending on relative rotational positions. The cylindrical members (18, 16) are relatively rotatable very easily by opposed manual rotation of the wheels to dispensing positions, a closed position, and a filling position in which major filling openings (78, 80) in the cylindrical members (18, 16) are aligned. The cylindrical members (18, 16) are indexed to exact relative positions for accurate dispensing, spill-free filling and air-tight closure.
Abstract:
A robot-like machine (10) for treating a surface area (33) within a boundary perimeter (31) (such as cleaning a carpet within a room) is guided using data developed from a graphic depiction representing the area (33). The graphic depiction may be for example, a blueprint (29). The machine (10) includes a self propelled chassis (75) having a working head (73) such as a vacuum nozzle (73b) mounted on it. A computing section (65) provides signals causing the machine (10) to move across the surface area (33) and a position sensor (69) generates a feedback signal representing the actual position of the machine (10). The computing section (65) is arranged for processing graphic data and the feedback signal and responsively generating command signals directed to each motor module (67). The machine (10) is capable of selectively treating portions of the surface area (33) such as those portions which become soiled more quickly.
Abstract:
A carpet cleaning machine (10) includes a pair of spaced, long-bristled, counter-revolving brushes (13) for stroking solvent-moistened cleaning granules (11) into and across the carpet fibers (16). As the fibers (16) are cleaned, the brushes (13) cast the granules (11) toward a machine shroud (29) in a 'throw pattern' (41). This inlet (47) of a vacuum nozzle (45) is located adjacent the bottom surface of the shroud (29) and is positioned generally coincident with the throw pattern (41). The machine (10) thereby applies cleaning granules (11) to a carpet (12) and more efficiently removes such granules (11) therefrom by vacuuming following carpet cleaning.
Abstract:
An applicator (10) for particulate compositions having a horizontally oriented apertured dispensing container (14), wheels (12) on either side, and an improved upright handle apparatus. The handle apparatus includes a yoke (18) with a cross member (22), a mounting bracket (30) affixed to the cross member, a pivotably attached slide mount which is preferably a support tube (38), a slidably mounted elongated handle (42), and lock members (48, 54, 56) on the mount and handle for selectively securing the handle member in the slide mount in either an upright use position or a horizontal carrying/storage position. The lock members are preferably spring-loaded button members with buttons receivable in a lateral opening in the support tube. A socket (58) in the bracket base (32) provides rigid connection of the handle member to the cross member. A stand (60) extends from the cross member to a floor-engaging distal end (62) so that the handle is off the ground while the applicator is untended.
Abstract:
A carpet cleaning machine (10) is convertible for brush-aided cleaning or vacuuming. The machine (10) includes a pair of powered brushes (13, 15) counter-revolving for stroking solvent-dampened carpet cleaning particles (17) through the carpet (11) and along carpet fibers during initial cleaning. A detachable, separately-powered pod (27) is connected to a machine-mounted vacuum nozzle (33) to pick up the dirt-laden particles (17) during brush-aided carpet vacuuming after initial cleaning. The pod (27) has first and second media (21, 23) selected to remove particles (17) of differing sizes from air flowing through the pod (27). During initial carpet cleaning when vacuum is not used, the pod (27) may be detached and used in another area for hand-vacuuming carpeted stairs and the like.
Abstract:
The improved carpet cleaning machine (10), intended for use with "dry" carpet cleaning systems using dampened particles (17), can be used for carpet "brushing" for dirt removal and for later vacuuming to remove dirt-laden particles (17). The machine (10) has a concentrically-mounted cyclone separator (21a) and a conical screen filter (23a) in series. The separator (21a) has air (25) flowing through it downwardly along a vortical path (37) and then upward along another path (45). Such upward-flowing air impinges on the outer surface (47) of the screen filter (23a) and many particles (17) adhering to such filter (23a) are dislodged. One or more additional media (67, 87) may be used to remove very fine particles (17).
Abstract:
A kit (10) for visual demonstration of principles relating to carpets and carpet care. The kit includes a horizontal base member, vertical members (30) removably securable in erect position with respect to the base member at their proximal ends (32), and means (28) on the base member to hold the vertical members in carrying position when not in their erect positions. A highly preferred base member is a transparent rigid box (12) with spaced upper and lower walls (22, 14), the vertical members being attached to the lower wall and extending loosely through openings (24) in the upper wall. The method includes applying dirt onto a shaft near its distal end and, when the shaft is erect on the lower wall of the preferred base member, executing a cleaning step. The cleaning step may involve applying a free liquid, which carries dirt through the opening into the rigid box, or rubbing with a damp wiper and then removing the dirty wiper from a position on top of the rigid box.
