  • Patent number: 7587972
    Abstract: A drink making machine (10) includes an ice shaving and dispensing unit (11) which provides a predetermined amount of ice, by weight, through a chute (21) to the pitcher (17) of a blending unit (12). A nozzle (30) is carried by the chute (12) and provides water through a nozzle opening (41) until a predetermined amount of water, by weight, is received by the pitcher (14). The water from the opening (41) is not allowed to directly impinge against the bottom of the pitcher (17). The water from the opening (41) is not allowed to directly impinge against the bottom of the pitcher (17) so that it does not adversely affect the weight measurements being taken.

  • Patent number: 7404527
    Abstract: A safety shield (10) is adapted to be used in a machine having a blade assembly such as an ice shaving and dispensing machine (11). The machine (11) has an ice bin (13) carried by a pedestal (12). An ice shelf (31) has an opening (32) and is positioned in the bin (13). The opening (32) provides access to the blade assembly which includes a shaver wheel (35) which directs ice to a blade (40). The shield (10) has a ring-shaped sidewall (50) which is carried by the bin (13) and which can extend upwardly out of the bin (13) to increase the capacity thereof. The shield (10) also includes a disk-shaped hub (51) which is connected to the side wall (50) by a plurality of arms (52). The hub (51) is larger than the opening (32) and is positioned over the opening (32) to prevent direct human access thereto. But ice may still pass through openings (53) between the arms (52) and through the opening (32) in the shelf (31) to be received by the blade assembly.

  • Patent number: 7104474
    Abstract: A device (10) for cleaning the inside of a container includes a base (11) carrying a tube (12). A hose (50) is received within the base (11) and is connected at one end to the bottom of the tube (12) and at the other end to a source of water via a quick disconnect assembly (60). A spray head (21) houses a plunger (30) which has a base (31) and a nose (32). A spring (37) urges the nose (32) of the plunger (30) out through an aperture (40) in the spray head (21). A flat washer seal (42) is positioned with a majority of its surface on a shelf (41) formed in the spray head (21). Ribs (43) on the shelf (41) engage the seal (42) on one side, and a rim (44) on the base (31) engages the other side of the seal (42). The quick disconnect assembly (60) includes a valve (66) which is maintained closed by a spring (67) so that when the hose (50) is disconnected from the source of water, or the water supply pressure is lost, backflow is prevented.
