| 20080264918 | SERVICING ARRANGEMENT FOR A PORTABLE AIR COMPRESSOR/GENERATOR - 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. | 10-30-2008 |
| 20080264919 | Portable Generator and Air Compressor Mounting Arrangement - 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. | 10-30-2008 |
| 20100147816 | Engine Driven Welder and Running Gear - 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. | 06-17-2010 |

| 20100147817 | ENCLOSED WELDER WITH RECESS PANEL - Embodiments of an enclosed welder that includes a recess disposed at a depth in a rear panel of the enclosure are provided. The recess may include at least one of an engine air filter, a blower housing, and a recoil start. The depth at which the recess is set back from the rear panel may be such that the engine air filter, the blower housing, and the recoil start each do not extend outward beyond the rear panel. A first air source may be configured to enter the enclosed welder via the air filter and combust fuel within an engine. A second air source may further be configured to enter the welder via the blower housing and cool the engine. | 06-17-2010 |
