Debris Chute Patents (Class 29/DIG102)
  • Patent number: 5586848
    Abstract: Apparatus capable of performing wet and dry machining processes such as a hobbing machine for producing spur and helical gears, shafts, splines, and the like, by wet and dry hobbing methods. The apparatus comprises means to remove metal chips resulting from the wet and dry machining processes from the apparatus via respective independent wet and dry chip outlets. The chip removal means comprises a transfer means located in the machine base with the transfer means being reversible in direction in order to convey metal chips, emanating from the machining process, to the respective wet or dry chip outlet. The chip removal means enables metal chips from wet machining processes to be conveyed to and discharged from an outlet in one side surface and metal chips from dry machining processes to be conveyed to and discharged from an outlet in another side surface.

  • Patent number: 5205686
    Abstract: An apparatus and method for the hydraulic removal and collection of cuttings from machine tool systems. The present invention provides a cutting removal and collection system comprising a housing at least partially enclosing a machine tool and a plurality of trays at the bottom of the housing for collecting the cuttings as they fall from the machine tool. Jets of fluid, such as a liquid coolant, are used to direct the cuttings along the trays and into a rotating drum. The drum has a hollow annular structure with fins disposed in an axial direction along its interior. The drum also has a perforated surface for allowing drainage of the fluid off of said cuttings and back into a tank positioned below the rotating drum. As the drum rotates, the fins carry the cuttings in the circumferential direction of rotation. Once the cuttings are carried to a certain height, gravity causes the cuttings to fall onto a drop tray positioned along a horizontal chord of the rotating drum.

  • Patent number: 4408642
    Abstract: A portable workbench featuring a stand structure supported by a plurality of wheels, and having a work surface with perforations therein for permitting liquid to drain therethrough, a self-draining catch basin disposed under the work surface to collect the draining liquid, and a removable reservoir connected to the catch basin to store the liquid for subsequent disposal. In one embodiment, the perforated work surface and catch basin form a detachable section for use in conjunction with existing stationary workbenches. The perforated work surface is coupled to the frame structure by a hinge which permits the work surface to swing away from the catch basin for easy access thereto. The position of this hinge and the supporting structure is such that the weight of the work surface and any objects that may be placed thereon is entirely supported by the stand structure and not by the hinge.
