Patent number: 11192200Abstract: A system, in one embodiment, may include a chassis, an engine coupled to the chassis, a generator coupled to the engine, and a rotary screw compressor coupled to the chassis independent from the engine. The engine may be configured to drive both the generator and the rotary screw compressor. A method, according to another embodiment, may include isolating a rotary air compressor from an engine and a generator in a common chassis. The isolating may include separately mounting the rotary air compressor and the engine with a resilient or distance adjustable connection in between. The isolating also may include resiliently mounting the engine, or the rotary air compressor, or both.Type: GrantFiled: December 26, 2014Date of Patent: December 7, 2021Assignee: Illinois Tool Works Inc.Inventors: Joseph N. Helf, John P. Laitala, Eric M. Kropp

Patent number: 9863374Abstract: An engine-driven generator that controls fuel vapor flow is provided. The engine-driven generator includes an engine having an air intake, wherein the engine is configured to drive a generator. The engine-driven generator also includes a fuel tank coupled to the engine and configured to provide fuel to the engine. The engine-driven generator includes a valve coupled between the air intake of the engine and the fuel tank. The engine-driven generator also includes a control device configured to transition the valve between a first position and a second position. The first position allows fuel vapor to flow between the fuel tank and the air intake of the engine and the second position inhibits the fuel vapor from flowing between the fuel tank and the air intake of the engine.Type: GrantFiled: February 27, 2017Date of Patent: January 9, 2018Assignee: Illinois Tool Works Inc.Inventors: John P. Laitala, Eric M. Kropp, Nathan J. Jochman

Patent number: 9000328Abstract: A system, in one embodiment, may include an engine, a compressor coupled to the engine, and an oil fill assembly coupled to the compressor. The oil fill assembly relocates an oil fill location from a bottom region of the compressor to a top region of the compressor. A system, in other embodiments, may include a compressor retrofit kit. The kit may include a first tube configured to couple with a drain or an existing oil fill disposed in a base region of a compressor. The kit also may include a second tube coupled to the first tube, wherein the second tube is configured to couple with a vent in the compressor. The kit may include a relocated oil fill section coupled to the first tube, the second tube, or a combination thereof. A system having a compressor retrofit kit attached to the case of the compressor is also provided.Type: GrantFiled: April 30, 2007Date of Patent: April 7, 2015Assignee: Illinois Tool Works Inc.Inventors: Joseph N.

Patent number: 8653416Abstract: A portable engine driven welder is provided that has a case enclosing an internal combustion engine and a welding generator, and a running gear that is attached to the case. The running gear includes a pair of rails and a pair of leading wheels connected to the rails toward the back wall of the case. A pair of trailing wheels is connected to the rails toward the front wall of the case. The leading and trailing wheels have different resiliency values with the leading wheels being more resilient or flexible than the trailing wheels. This allows the leading wheels to act like a suspension system for the portable engine driven welder and running gear by soaking up or absorbing impacts instead of transmitting them therethrough so as to reduce exposure of the portable engine driven welder to such impacts.Type: GrantFiled: October 19, 2009Date of Patent: February 18, 2014Assignee: Illinois Tool Works Inc.Inventor: John P.
