Patent number: 11939983Abstract: A centrifugal blower is described herein. The centrifugal blower may be a belt-driven geared centrifugal blower. The centrifugal blower may comprise an impeller, an inlet, and an outlet. The impeller pulls air in through the inlet, compresses and speeds up the air, and directs the air out the outlet. A motor may power a pulley system coupled to the belt that, in turn, drives a gear set. The gear set then drives the impeller. A mounting frame for the centrifugal blower may comprise a plurality of mounting holes for increasing the airflow to the gear set for cooling there. A belt tensioner may be coupled to the pulley system for setting a preload in the pulley system. An adjustment system for adjusting the tension provided by the belt tensioner is disclosed.Type: GrantFiled: September 13, 2022Date of Patent: March 26, 2024Assignee: Accessible Technologies, Inc.Inventors: Michael A. Carlson, Ryan L Jackson, Justin R. Gomez

Patent number: 8439019Abstract: A compressed air delivery system in which power from a power supply is transmitted to a rotary air compressor through a dry running, continuous variable transmission (CVT) utilizing a belt coupled between two pulleys enclosed within a CVT housing. The air pressure differential created by the rotary air compressor is used to urge cooling air through the CVT to cool the CVT belt. The pressure differential may be utilized to push cooling air into the CVT housing or to draw cooling air through the CVT housing. In one embodiment, a portion of the compressed air discharged from a supercharger may be routed through a bleed line and into the CVT housing.Type: GrantFiled: February 25, 2010Date of Patent: May 14, 2013Assignee: Accessible Technologies, Inc.Inventors: Michael A. Carlson, Kenneth C. Jones

Patent number: 8439020Abstract: A supercharger assembly includes a dry-running CVT coupled to a speed multiplying gear set, which is in turn coupled to a centrifugal supercharger. The CVT includes a CVT housing which has an opening formed therein to provide access to a face of the driven pulley, and a plurality of equally spaced bolt receivers arranged in a circle around the opening. The gear assembly includes a gear housing formed separate from the CVT housing. The gear housing has a plurality of bolt holes formed in it which are arranged in a circle and alignable with respective ones of the bolt receivers. The gear housing is selectively rotatable relative to the CVT housing by moving each of the bolt holes from alignment with a first respective one of the bolt receivers and into alignment with a second respective one of the bolt receivers and then installing fasteners therein.Type: GrantFiled: February 25, 2010Date of Patent: May 14, 2013Assignee: Accessible Technologies, Inc.Inventors: Michael A. Carlson, Kenneth C. Jones

Publication number: 20110194904Abstract: A compressor airflow controller is operable to control airflow through a centrifugal compressor. The controller drives the centrifugal compressor and determines if a flow irregularity (e.g., an error in gas flow velocity) has occurred. If a flow irregularity is determined, the controller reduces the irregularity by adjusting compressor operation to thereby change the compressed gas flow.Type: ApplicationFiled: April 20, 2011Publication date: August 11, 2011Applicant: ACCESSIBLE TECHNOLOGIES, INC.Inventor: Michael A.

Publication number: 20100135771Abstract: A centrifugal supercharger includes a case presenting a compressor chamber and a transmission chamber. An impeller in the compressor chamber is mounted to a shaft that extends into the transmission chamber. The impeller shaft is drivingly connected to a power input shaft by intermeshing gears provided on the shafts. A portion of the transmission chamber defines a fluid reservoir in which lubrication fluid is held. The intermeshing gears, as well as the bearing assemblies supporting the shafts, are located outside the fluid reservoir portion of the transmission chamber. A rotatable fluid-propelling element partly submerged in the lubrication fluid contained within the reservoir portion ensures that sufficient but not excessive lubrication fluid is supplied to the intermeshing gears and the bearing assemblies. A dedicated lubricant reserve system ensures that the required operating level of fluid is provided to, and maintained in, the reservoir portion.Type: ApplicationFiled: February 1, 2010Publication date: June 3, 2010Applicant: ACCESSIBLE TECHNOLOGIES, INC.Inventors: Daniel W.

Patent number: 7654876Abstract: A personal watercraft is disclosed as including an engine and a forced air induction system including an aftermarket supercharger. The aftermarket supercharger replaces the personal watercraft's original-equipment supercharger and increases the charge of compressed air provided to the engine. The preferred supercharger incorporates a spur gear that includes a smaller pitch diameter than the original-equipment supercharger. The smaller spur gear and engine flywheel thereby provide an increased gear ratio and permit greater supercharger rotational speeds when compared with the original supercharged engine. In order to permit intermeshing engagement with the engine flywheel, the spur gear is axially offset from the original spur gear axis. However, the supercharger case maintains the same engine-mating surface as the original-equipment supercharger so that the case may be received within a complemental socket of the engine housing.Type: GrantFiled: May 22, 2006Date of Patent: February 2, 2010Assignee: Accessible Technologies, Inc.Inventors: Daniel W.
