  • Patent number: 4384544
    Abstract: For applying a liquid, such as liquid wax, to a continuously fed sheet material a first pair of cylindrical rollers, each having a smooth surface which is exposed to and wetted by the liquid to be applied, are rotatably mounted about substantially parallel axes and spaced apart to permit intimate tangential contact therebetween with both sides of the sheet material to be coated. A second pair of cylindrical rollers located a distance from the first pair are similarly mounted and positioned to make contact with the sheet material in like manner. A pair of cylindrical engraved rolls, each having an array of guadrangular cells formed along the surfaces thereof, are respectively positioned between each of the first and second pairs of rollers and are rotatably mounted on movable axes so that the engraved rolls urge against one or both of the roller pairs during rotation.

  • Patent number: 4352413
    Abstract: An air brake includes a friction liner attached to a piston-like member which is arranged to reciprocate with respect to a stationary member. The piston-like member is urged into its inoperative position without the use of a biasing element such as a spring or spring-like member. spThis is a division of application Ser. No. 888,190 filed Mar. 20, 1978, now U.S. Pat. No. 4,227,421.

  • Patent number: 4281556
    Abstract: A first carriage, which is arranged to vertically reciprocate within a first housing, is provided with two air clutches and a continuously moving chain. The chain is arranged to move over co-planar spaced sprockets so as to present one direction of chain motion to the left side of the carriage and a second direction of chain motion to the right side of the carriage. The carriage is also provided with two chain engaging sprockets each controlled by a respective one of two air clutches. The chain engaging sprockets on the carriage normally idle with chain motion. However, actuation of one of the controlling air clutches halts the spinning of its associated sprocket and forces the sprocket and clutch to act as a unit to thereby move the carriage upwardly or downwardly along the length of the chain in a direction dependent upon which portion of the continuously moving chain was so engaged. Means are provided to automatically reverse the stroke, to vary the length of the stroke and to vary the speed of the stroke.

  • Patent number: 4227421
    Abstract: A carriage reciprocator and positioner is provided with two air clutches and a continuously moving chain. The chain is arranged to move over co-planar spaced sprockets so as to present one direction of chain motion to the top of the carriage and a second direction of chain motion to the bottom of the carriage. The carriage is also provided with two chain engaging sprockets each controlled by a respective one of two air clutches. The chain engaging sprockets on the carriage normally idle with chain motion. However actuation of the controlling air clutch halts the spinning and forces the sprocket and clutch to act as a unit to thereby move the carriage linearly along the length of the chain in a direction dependent upon which portion of the chain was so engaged. Means are provided to automatically reverse the stroke, to vary the length of the stroke and to vary the speed of the stroke.
