Publication number: 20160270612Abstract: An ergonomic vacuum-assist scraper tool has an arcuately curved head in which a scraper blade is mounted at either of a front position or a rear position, a handle or grip portion, and a tubular connector portion adapted to receive a male or female vacuum hose fitting. The head has a cavity defined between front and back walls, with the front and back walls converging along an arc to a mouth or slot opening. The grip portion is hollow and tubular, extending proximally from the head, to the vacuum hose-accepting tubular connector. A scraper blade can be removably mounted at either of the blade mounting positions. The tool is formed of upper and lower halves that snap together along a partition line.Type: ApplicationFiled: March 14, 2016Publication date: September 22, 2016Applicant: Oneida Air Systems, Inc.Inventors: Robert M.

Patent number: 9399184Abstract: A cyclonic portable vacuum cleaner/dust collector has a cyclonic chamber and a filter chamber. The filter chamber contains a filter cartridge with a hollow core positioned over the discharge opening of a motor plate that closes the filter chamber. A vacuum blower is mounted on the motor plate, with an intake tube at the discharge opening of the motor plate. An anti-deflagration screen mounted upon the discharge opening of the cover plate of the filter chamber. The anti-deflagration screen is in the form of a metal mesh creating a multiplicity of small passages to permit exhaust air flow from the filter chamber but blocking any flame front. The screen may be hemispherically domed.Type: GrantFiled: February 12, 2013Date of Patent: July 26, 2016Assignee: Oneida Air Systems, Inc.Inventors: Robert M. Witter, Jeffrey Hill, John J.

Patent number: 9370740Abstract: A stacking modular filter arrangement may be employed as a final filter for the dust collector for woodshop or other environment in which dust in an air stream is separated out and the exhausted air is filtered in the final filter to return to the ambient. The filter arrangement employs at least first and second filter modules of similar section, and a number of clamp members to hold facing end plates of the filter modules and pull the end plates against one another with one or more gasket members compressed between them. This arrangement permits the available filter area of the final filter to be customized to the customer's needs.Type: GrantFiled: January 30, 2014Date of Patent: June 21, 2016Assignee: ONEIDA AIR SYSTEMS, INC.Inventors: Jeffrey Hill, John J.

Patent number: 9125535Abstract: A cyclonic portable vacuum cleaner/dust collector has a cyclonic chamber and a filter chamber. The filter chamber contains a filter cartridge with a hollow core positioned over the discharge opening of a motor plate that closes the filter chamber. A vacuum blower is mounted on the motor plate, with an intake tube at the discharge opening of the motor plate. An annular pulse-cleaning plate is positioned over an associated annular opening that surrounds the motor plate discharge opening and has an open center that slides up and down on the intake tube of the vacuum blower. A bail handle or lever extends from the pulse-cleaning plate to a handle portion outside the cover or shroud. The handle is pushed down to lift the pulsing plate to provide a reverse pressure air pulse to the filter to blast off accumulated dust. An anti-deflagration screen may be present at the center of the motor plate.Type: GrantFiled: February 12, 2013Date of Patent: September 8, 2015Assignee: ONEIDA AIR SYSTEMS, INC.Inventors: Robert M.

Patent number: 8919602Abstract: A protective shield fits onto a fuel cylinder that is mounted on a propane-powered or LNG-powered vehicle, with a cylindrical flange on the tank surrounds a tank valve. The protective shield is formed of a cylindrical wall of a rubber-like material that fits snugly onto the cylindrical flange of the fuel tank, and has a window affixed into its upper end of the cylindrical wall. The window can be a disk of transparent plexiglass. There are openings in the cylindrical wall to access the tank valve. The shield provides visibility of the tank valve but prevents any spray of the fuel that may escape from the tank valve from reaching the worker's face or other exposed skin.Type: GrantFiled: May 10, 2013Date of Patent: December 30, 2014Assignee: Tank Right Systems LLCInventors: Shawn Nolan, Michael Fey, Richard R.

Patent number: 8514090Abstract: A level detector or sensor for a dust collection system has a threaded housing that seats in a penetration in the lid of a dust collection drum or other container, and can be adjusted mechanically in its mounting. The sensor has an adjustment to control the distance at which it picks up light off the collected material. An elongated flexible cable connects the sensor with an alarm strobe, which may be a low-power LED device, and can be positioned at a convenient location remote from the drum.Type: GrantFiled: November 5, 2010Date of Patent: August 20, 2013Assignee: Oneida Air Systems IncInventors: Robert M Witter, Jeffrey Hill, John J Fitzsimmons

Patent number: 8491686Abstract: A dust collector arrangement has a dust separator supported on a frame, with a lid for the dust collection barrel is mounted onto the frame below it. The lid is supported at a fixed elevation above the surface of the shop floor to create a space or clearance between the rim of the dust collection barrel and the lid. The barrel is supported on casters, and can be rolled into place under the rim, and can be rolled out for emptying. Over-center latches positioned at intervals around the upper part of the barrel side wall, engage corresponding structure on the lid. These pull the barrel upwards against the lid and with the barrel casters lifted off the floor surface. The latch members release to lower the barrel for emptying.Type: GrantFiled: February 17, 2011Date of Patent: July 23, 2013Assignee: Oneida Air Systems, Inc.Inventors: Robert M.

Patent number: 8151385Abstract: A shower curtain and support system employs an elongated rail supported at the shower or tub. The rail extrusion can be an extrusion with an inverted U profile, with an open slot or slots at its base. There are glides, e.g., nylon members with a ball, hemisphere, or other wide head portion and shaft that projects out through the slot from the open interior of the rail. The glides have one or two hook structures for attaching to a fabric curtain and a vinyl curtain liner. In one preferred version, there is a liner hook and spring retaining arm on one side that fits into the grommet at the top of the liner. On the other side is a short arm with a button that fits into a button hole on the cloth or fabric curtain. The curtain has blind button holes or grommets at its upper hem, so that the hook structure, e.g., button, does not show.Type: GrantFiled: September 23, 2008Date of Patent: April 10, 2012Assignee: Kartri Sales Company, Inc.Inventors: M.

Patent number: 5944074Abstract: An interchangeable additive injection apparatus provides a plurality of flow paths from one or more upstream additive tanks to one or more downstream fuel containers. A plurality of additive lines converge into an additive conduit at a manifold disposed within the apparatus. A plurality of valves associated with the additive lines are selectively opened and closed to isolate one of the flow paths. A metering device is disposed along the additive conduit for measuring the flow of additive therethrough. A reversible, multiple port housing surrounds at least the valves and manifold. In a forward orientation, a plurality of upstream ports are coupled to upstream additive tanks, and a downstream port is coupled to a fuel tank. By reversing the housing, the apparatus is placed in a reverse orientation wherein the upstream port is connected to an upstream additive tank and a plurality of downstream ports are connected to downstream fuel tanks.Type: GrantFiled: February 18, 1998Date of Patent: August 31, 1999Assignee: Chemical Control Systems, Inc.Inventors: Ricky E.

Patent number: 4503955Abstract: A modular carrying case of all metal construction that includes a top cover section and a bottom cover section that can be closed against each other to provide a totally enclosed case or alternatively closed against one or more center sections to provide a case of greater carrying capacity. Each of the cover sections and the center section are fabricated from a metal extrusion that is formed into a generally endless loop. The peripheral edges of the abutting sections are equipped with interlocking joints that serve to form an extremely tight closure when the case is placed in a closed condition.Type: GrantFiled: March 11, 1983Date of Patent: March 12, 1985Inventor: John J.
