  • Publication number: 20050210616
    Abstract: A manually operated scraper tool includes a handle that seats a blade retaining component that freely and rotatably holds a substantially circular cutting blade thereto. An alternate attachment embodiment of the scraper tool includes a tool receiving body, rather than a handle, that may be received and driven by a power tool.

  • Patent number: 5217144
    Abstract: A collapsible tube dispenser is disclosed for use with collapsible tubes that contain highly viscous materials, such as silicone gasket RTV. The dispenser provides two engaging plates for squeezing the sides of a collapsible tube, which causes the contents of the tube to be expressed from its open end. The dispenser also includes two handles which can be gripped by a single hand of a human user. When the handles are kept apart from one another, a collapsible tube can be inserted into the slot formed between the engaging plates of the dispenser. When the handles are squeezed together, the engaging plates apply force to the sides of the tube, thus squeezing out a very controlled amount of highly viscous material. The dispenser is very easy to use, in that it can produce a bead of highly viscous material upon a target having a very narrow line width, and having great positional accuracy.

  • Patent number: 4597721
    Abstract: A double-acting air-powered diaphragm pump having a pair of identical pump assemblies detachably secured within a frame-like manifold assembly. Each of the pump assemblies contains a pair of mating halves and a web-like resilient diaphragm defining an air cavity and a fluid cavity. Each of the diaphragms is operated by means of a centrally attached shaft, the facing ends of the shafts being joined by a chain link which allows for potential misalignment. The pump assemblies, which are substantially identical in construction, may be easily and individually removed from the manifold assembly for repair or replacement.

  • Patent number: 4517917
    Abstract: A device for preventing trailing of glue extruded by an exclusion nozzle following termination of the dispensing of the glue. A pair of spaced apart orifices are positioned to direct a thin jet of air for a brief period of time on either side of the stream of glue being dispensed at the moment of glue cut-off to momentarily entrain the stream and draw it generally in the direction of the path of travel of the workpiece. The air jets are oriented so as not to touch or impinge on the glue stream, thereby preventing break-up of the glue stream.

  • Patent number: 4486001
    Abstract: An air actuated adhesive application control valve using a resilient diaphragm to control reciprocation of the valve stem. Unsupported portions of the diaphragm are supported by a layer of the incompressible adhesive trapped within a fluid cavity adjacent one major surface of the diaphragm. Adhesive is permitted to enter the fluid cavity when the valve is in the closed position, but is prevented from escaping therefrom by a separate valve mechanism carried by the valve stem when the valve is in the opened position. The second valve element also serves as a stop to limit travel of the reciprocating stem, thereby controlling the valve opening clearance.

  • Patent number: 4208236
    Abstract: In a labeling machine for cylindrical objects such as cans, having conventional means to apply glue to such object in a line parallel to the axis thereof, and having means for causing the object to roll over a stack of labels such that one end of the uppermost label in the stack is picked up by adhering to said line of glue, and is rolled around the object as it progresses in its rolling path; means are disclosed to apply a line of glue under pressure to the uppermost label in the stack at its trailing end in timed relation to the movement of the object in its path so that the trailing edge of the label adheres to the object as it continues its rolling path. Means are provided to adjust for objects of varying length and diameter, and for labels of different lengths.
