  • Patent number: 5285971
    Abstract: A hand held spreader having the bottom-face of the hopper portion at an angle with respect of the horizontal and having the handle for holding the device disposed directly below the hopper and so directly below the weight of the hopper; the handle is angled so as to afford an in-line action between the trigger of the handle and the slide of a dispensing mechanism, thus avoiding any requirement or a linkage between the trigger and the slide mechanism. Also the gear-box portion of the device is of a simple clam-shell design that allows the rotary drive shaft of the device to be removably supported on opposite sides of its load bearing section by means of bearing supports on both sides of at least one of the gears. The supports are part of the separate halves of the housing itself, thus avoiding the need for additional or separate bearing structures.

  • Patent number: 5271527
    Abstract: A pharmaceutical dispenser includes a housing (4), containing two pharmaceutical cartridges (32,34), slidably mounted to a sliding body (100). A replaceable needle manifold assembly (10) is mounted to the housing and fluidly couples the cartridges with a hypodermic needle at a common exit. The sliding body is part of a reciprocating drive assembly used to drive a pair of drive stems (88) against the pistons (96, 98) of the cartridges, thus forcing predetermined amounts of the pharmaceuticals out the needle. The movement of the sliding body between retracted and post-injection positions remains constant. However, the amounts and proportions of the pharmaceuticals injected during the delivery stroke is chosen by the user using stroke adjusters (182) carried by the sliding body. A bistable status flag (186) is mounted to the sliding body to indicate when the sliding body is in the post-injection and the retracted positions. The dosage adjustments are made when the sliding body is in the post-injection position.

  • Patent number: 5154702
    Abstract: A variable dosage dropper system improves upon the conventional dropper assembly (container, cap, pipette, bulb) by providing an annular overcap housing which completely encloses the cap and bulb to provide tamper resistant protection and has a locking collar at its lower end to secure the cap within the housing. A plunger slidably, rotatably, and sealingly mates with the housing. The plunger contacts and compresses the bulb when pushed downward toward the housing a predetermined distance corresponding to various dosages and allows the bulb to return to its decompressed position when released. The system is also adapted to resist undesired opening of the container by children.

  • Patent number: 4708265
    Abstract: A practical and simple system that automatically measures and dispenses grain and powder type food products, such as sugar and flour contained within a canister type holder. The system consists of a drawer compartmentalized into precisely measured divisions with the topside uncovered and the bottomside selectively covered or uncovered by a moveable slide that allows for the pulling out of the drawer without spillage. The drawer will stop at one of several preset measured positions. These positions are controlled by a spring-pressured arm. With the drawer in a selected position the contents of the outward division or divisions of the drawer are dispensed accurately and immediately by pushing inwardly the moveable slide covering the bottom side. When the drawer is pulled outward an attached trailing horizontal upper slide prevents any of the contents within the canister from filling the empty area behind the drawer when the drawer is pulled out.
