Patent number: 6598816Abstract: A chip detangler is provided for a machine having a discharge trough for collecting fluid containing metal chips. An auger disposed along a longitudinal axis of the trough advances the fluid and chips downstream through an exit area. The detangler preferably comprises a snagging bar fixed relative to the machine and disposed at least partially within the trough to engage nests of chips traveling past the snagging bar. The forces induced by the auger tears apart nests engaged with the snagging bar into smaller, more suitable sizes.Type: GrantFiled: November 16, 2000Date of Patent: July 29, 2003Assignee: Barnes International, Inc.Inventors: Thomas W. Lenhart, John L. Dahms

Publication number: 20030010705Abstract: The present invention provides a filtering apparatus generally comprising a reservoir containing a pool of dirty fluid, the reservoir defined at least in part by a pair of laterally spaced side walls. A drum is rotatably supported within the reservoir, the drum having a generally cylindrical body having a first end, a second end, and an opening therebetween to pass fluid. A filter element is connected to the drum body and covers the opening to filter fluid flowing into the drum. The drum body is journalled about its outer surface to the reservoir for rotation therein. As such, the drum does not require any end walls to support the drum, and the entire end of the drum is wide open to the flow of fluid, which increases the rate of flow through the filter, and permits the filter to be used with a wide range of fluid flows. Unique adjustment of the drum is also provided.Type: ApplicationFiled: July 13, 2001Publication date: January 16, 2003Applicant: Barnes International Inc.Inventor: Thomas W. Lenhart

Patent number: 5527214Abstract: The tool includes a body which supports angularly spaced roughing hones and angularly spaced finishing hones for radially inward and outward movement between collapsed and expanded positions. Expansion of the roughing hones is effected by axially spaced ramps when a rod is moved linearly in one direction while expansion of the finishing hones is effected by additional axially spaced ramps when the rod is shifted linearly in the other direction. By turning an adjusting nut from the free end of the tool body, the axial spacing between the ramps of the roughing hones may be changed for purposes of adjusting the inclination of the roughing hones. A second adjusting nut coaxial with the first nut may also be turned from the free end of the tool body to change the axial spacing between the ramps of the finishing hones and thereby effect adjustment of the inclination of the finishing hones.Type: GrantFiled: April 8, 1994Date of Patent: June 18, 1996Assignee: Barnes International, Inc.Inventor: Mark R. Estabrook

Patent number: 5496470Abstract: A separator with a continuously rotating magnetic drum which is partially disposed in a liquid flow path to attract and thereby separate magnetic particles from liquid delivered to the flow path. The separator includes an inclined scraper blade which removes the magnetic particles from the drum. The magnetic field of the drum penetrates the inclined scraper blade causing particles to build up on the blade, thereby allowing coolant which was carried with the particles on the drum to drain back to the flow path. A pushing force caused by particles subsequently delivered to the scraper blade by the rotating drum shoves the buildup of particles past the magnetic field acting on the scraper blade and down a discharge chute into a waste container.Type: GrantFiled: May 27, 1994Date of Patent: March 5, 1996Assignee: Barnes International, Inc.Inventor: Thomas W. Lenhart

Patent number: 5417525Abstract: Burrs formed at the ends of a bore during a honing operation performed by a single pass honing tool are removed by a deburring attachment which is carried on the leading end of the tool. The attachment includes one set of spring-loaded blades which remove burrs at one end of the bore as the tool is retracted from the bore and further includes an axially spaced set of spring-loaded blades which remove burrs at the opposite end of the bore during retraction of the tool.Type: GrantFiled: March 10, 1994Date of Patent: May 23, 1995Assignee: Barnes International, Inc.Inventor: Thomas W.

Patent number: 5328611Abstract: A filter drum with a tubular filter belt is journaled for rotation on a pipe which serves to supply filtered coolant to spray nozzles located within the drum and operable to backwash the filter belt.Type: GrantFiled: June 26, 1992Date of Patent: July 12, 1994Assignee: Barnes International, Inc.Inventor: Thomas W.

Patent number: 5230793Abstract: Individual machine tools are supplied with coolant by individual filtration units which separate metal chips from the coolant in order to provide a clean supply to the machine tool. A central vacuum unit is capable of sucking chips from all of the filtration units and delivering the chip to a central processing area for disposal or salvage. To enable chips of different metals to be separated and salvaged, the vacuum unit is capable of discharging its output to a selected one of a plurality of hoppers in the central processing area. In order to further increase the flexibility and salvageability of the overall system, a plurality of vacuum units may be associated with the filter units, with any given vacuum unit being operable to selectively serve any given filter unit and capable of being selectively served by any given hopper.Type: GrantFiled: September 25, 1991Date of Patent: July 27, 1993Assignee: Barnes International, Inc.Inventors: Thomas W.
