Hood Encased Cutter Patents (Class 29/DIG86)
  • Patent number: 6116616
    Abstract: A sealing arrangement is provided to close off and seal a gap between undersurfaces of a machine tool installation and a coolant collection channel. The sealing arrangement includes a pair of lengths of sealing hoses inflated with air pressure to close off and seal the gap. The inflated hose seals accommodate the variable gap created by sloping collection troughs to simplify the construction thereof.

  • Patent number: 5607269
    Abstract: A milling apparatus is disclosed which includes a milling machine having a milling cutter which is sealingly isolated from the milling machine within an enclosed work area, a support fixture disposed within the enclosed work area for supporting a work piece, and a mechanism for moving the milling cutter along a predetermined path relative to the work piece. Preferably, the milling apparatus is employed to cut bone into small fragments for subsequent utilization, and the sealed isolation of the milling cutter inhibits cross-contamination between differing work pieces.

  • Patent number: 4638695
    Abstract: An exhaust duct is arranged vertically slidably on a vertical board saw so that it always follows the vertical movement of the sawing unit during horizontal cutting. The exhaust duct is formed by a U-shaped profile, in which an endless driven band is guided. A slot provided in the band is located in front of the saw blade (S) in every position of the sawing unit; the sawdust thrown off by the saw blade thus passes through the slot into the space enclosed by the band and is exhausted. A sealing element is fitted on the front band side just in front of the slot. The apparatus ensures a virtually 100% discharge of the chips and sawdust in the case of horizontal cutting, which is of great significance particularly in sale rooms and exhibition rooms, and contributes to humane conditions in the workshop.

  • Patent number: 4543021
    Abstract: A safety shield, adapted for securement to a milling machine, drill press, and the like, is rotatable to permit easy access to a workpiece, and is provided with a drag resistance to such rotation to prevent inadvertent return of the safety shield to the original workpiece area when not so desired.

  • Patent number: 4514936
    Abstract: Method and apparatus for collecting dust and shavings produced by a drum and disc lathe. The apparatus comprises a sealed housing which is adapted to enclose the entire grinding or cutting area of the lathe and trap airborne particles suspended therein. A brake drum or disc is attached to the lathe arbor within the housing through a housing access door prior to the machining operation. The cutting tool extends from the lathe into the housing through an orifice which is covered by a plurality of sealing strips. As the drum or disc is machined, the suspended asbestos and metal dust is removed from the housing to a collection receptacle by the directional air flow from a fan and the heavier metal shavings are collected in a tray located on the housing floor.

  • Patent number: 4414783
    Abstract: A coolant system for use with a cutter of the type having a vertically disposed rotatable cutter wheel for cutting metallurgical samples and other objects. Such a cutter has a motor-driven rotatable abrasive or metal cutting wheel or blade, and a workpiece holder which holds a specimen workpiece from which a section is to be sliced off. Either the cutter wheel or the workpiece holder is movable to bring the workpiece into engagement with the cutter wheel. The coolant system is combined with a blade guard which covers a major portion of the rotatable cutting blade for safety reasons, and the coolant system distributes a coolant fluid in an advantageous manner onto the center of the vertically disposed rotating cutting blade on both sides thereof so as to bathe the workpiece over the entire cutting area. The coolant system is primarily intended for use with a cutter of the type where the workpiece is moved into engagement with the cutter wheel during a cutting operation.

  • Patent number: 4253362
    Abstract: A guard casing encloses a substantial portion of the blade of a circular power saw. A cylindrical tube is carried by the casing for connection to a source of vacuum, the cylindrical tube having a slot extending longitudinally from one end thereof for accommodating therein a peripheral segment of the saw blade so that the sawdust produced by the blade is more efficiently collected. The cylindrical tube is adjustably mounted so that its slot can be appropriately positioned relative to the saw blade.

  • Patent number: 4162647
    Abstract: A guard for a milling machine comprises a combination of rods and blocks for supporting guard panels relative to the milling tool to provide for an adjustment of the panels relative to the tool axially of such tool. A plurality of mounting bars extend away from the tool area in a plane, each supporting one of a set of mounting blocks. A pair of support rods extend in that plane each from an opposite side of a mounting block, and each transverse to its mounting bar. A pair of support blocks each support one of a pair of guard panels.
