Hermann E. Gasser has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5228172
    Abstract: An apparatus for depositing a textile fiber strand in a spinning can. Mounted in a housing are two rotary plates (4, 5) for rotation about their respective axes, one of the rotary plates being smaller and mounted at an eccentric position inside the outer periphery of the other rotary plate. The rotary plates are connected to a lay-down pipe through which the fiber strand is guided. The two rotary plates are coupled to one another by a revolving belt transmission, the lay-down pipe being composed of a plurality of pipe sections (18, 22, 23, 19, 8) rotatable relative to one another and associated with the rotary plates (4, 5). Disposed adjacent the outlet end of the lay-down pipe is a pneumatic pressure injector (48) for automatically threading the fiber strand.

  • Patent number: 4967449
    Abstract: The present invention refers to a device for depositing a textile sliver in a can, comprising a bent delivery pipe, which is adapted to be rotated about a substantially vertical axis and the mouth of which ends in front of a stationary wall projecting into the cross-section of the mouth of the bent delivery pipe.The task to be solved by the present invention is the task of simplifying a device of the type mentioned at the beginning and treating the sliver with care at the same time.In accordance with the present invention, this task is solved by the features that a pressure-exerting member, which is directed towards the stationary wall and which moves together with the belt delivery pipe, is arranged behind the mouth of the bent delivery pipe when seen in the direction of rotation, the coefficient of friction of the wall being higher than the coefficient of friction of the pressure-exerting member, when measured in the direction of rotation of the bent delivery pipe.
