Patent number: 9839948Abstract: A fume evacuation system is designed to remove smoke, fumes, and particulate from a metal-working or other application. The system may include a cart-type base unit or may be incorporated into a fixed or semi-fixed installation that uses suction to draw air (e.g., containing smoke, fumes, and particulate) away from the metal-working application. The fume evacuation system includes a hood that creates an arduous flow path and varying velocity profile, which cools and separates any particulate matter in the suctioned air. The arduous flow path may include multiple sharp turns created by an inner deflector component and an inlet tube. The inlet tube may further contain baffles to cool particulates from the suctioned air.Type: GrantFiled: January 29, 2013Date of Patent: December 12, 2017Assignee: Illinois Tool Works Inc.Inventors: John C. Leisner, Brian J. Hammers, Allan T. Hilbert

Patent number: 9821351Abstract: A fume extraction hood is designed to be positioned above a welding, cutting, or other metal-working location and to remove hot gases, smoke and fumes produced during these processes. The hood forms a box-like structure with an extractor rail structure disposed in an internal volume of the hood. The extractor rail structure comprises panels that force sharp turns in the gases, causing particulate matter to drop out of the gases both outside and inside the extractor rail. A primary path for gases accelerates and re-directs the gases entering into the extractor rail, and within the rail. The rail may form a dropout tray that can be removed for cleanout of collected particulate. The side and end rails of the hood may create a secondary path for gas not directly intaken into the extractor rail. This secondary path is re-directed towards the extractor rail, where gas is collected and particulate is forced to drop out as it joins the primary path.Type: GrantFiled: September 11, 2012Date of Patent: November 21, 2017Assignee: ILLINOIS TOOL WORKS INC.Inventor: Brian J.

Patent number: 9604266Abstract: An airborne component extraction system comprises a source of a positive pressure air stream and a source of a negative pressure air stream. Conduits allow the positive pressure air stream to be channeled to a work area, and the negative pressure air stream to be drawn from the work area to pull airborne components away from the work area. A manifold receives the conduits and aids in directing both air streams between the sources and the conduits. The manifold may support the conduits in the form of an arm that can be rotated while directing the air streams.Type: GrantFiled: February 14, 2013Date of Patent: March 28, 2017Assignee: ILLINOIS TOOL WORKS INC.Inventors: Brian J. Hammers, Adam Joseph Frank, William Maske

Patent number: 9468958Abstract: A extraction system is designed for metal working and other applications. The system may comprise a cart-type base or may be incorporated into a fixed or semi-fixed installation. A blower delivers a positive pressure airflow to a hood that creates an air region by directing the air through an annular space between inner and outer shrouds, impacting the air against a single generally perpendicular flange. Return air from the operation may be mixed with fresh air, both of which may be filtered, to supply the positive pressure air. Both air streams to and from the hood may be adjusted to optimize operation. Adjustments may be made at the base unit or remotely.Type: GrantFiled: February 14, 2013Date of Patent: October 18, 2016Assignee: ILLINOIS TOOL WORKS INC.Inventors: Brian J.
