Patent number: 11565394Abstract: A tool with two sequential gear trains and gear carrier assemblies adapted to be recessed into internal gears. The internal gear assembly also prevents rotation of the internal gear assembly relative to a housing of the tool. For example, the internal gear assembly can include a first gear train and second gear train sequentially coupled to the first gear train, wherein a first ring gear and first planet gears of the first gear train are substantially similar to a second ring gear and second planet gears of the second gear train.Type: GrantFiled: October 28, 2019Date of Patent: January 31, 2023Assignee: Snap-on IncorporatedInventors: David A. Cyborski, Joshua M. Beer, Matthew D. Patterson

Patent number: 11545871Abstract: A motorized hand tool such as a cordless ratchet wrench that has a motor, and a housing that encloses or houses the motor. The motor includes one or more exhaust ports that expel exhaust air out of the motor. The housing includes one or more exhaust ports and inwardly projecting protrusions or deflectors that extend around the exhaust ports. The inwardly projecting protrusions/deflectors extend in a direction towards the motor exhaust ports, and/or are at least partially disposed in the motor exhaust ports to direct exhaust air out of the housing and prevent exhaust air from recirculating near the motor and electronic components of the tool.Type: GrantFiled: September 2, 2020Date of Patent: January 3, 2023Assignee: Snap-on IncorporatedInventor: David A. Cyborski

Publication number: 20220305603Abstract: The present invention relates to a motor timeout of a power tool. When a trigger of the tool is unintentionally actuated, power is provided to a motor of the tool to cause an output assembly of the tool to operate. This can be problematic when the tool is being stored. To address this situation, the tool initiates or starts a motor timer when the motor is running at any nonzero speed. If the trigger remains continuously actuated, with the motor running at any nonzero speed, and the motor timer reaches a threshold limit, the tool ceases or discontinues to allow power to be provided to the motor, thereby shutting off the motor. This reduces the power source from being unintentionally discharged, and the chance of the tool creating a situation where the output assembly can unintentionally cause damage to the storage mechanism or other surroundings.Type: ApplicationFiled: March 14, 2022Publication date: September 29, 2022Applicant: Snap-on IncorporatedInventors: Michael T. Rajzer, Jason Genz, David A. Cyborski, Jeremy Zorns, Christoffer S. Fox, Patrick F. Healy

Patent number: 9523291Abstract: A valve actuation system is disclosed for an engine. The system may have at least one gas exchange valve, a rocker shaft, a camshaft, a rocker arm connected to the rocker shaft and operatively engaged with the camshaft, a valve bridge engaged with the at least one gas exchanger valve, a lash adjuster disposed in the valve bridge, and a button configured to slide on the valve bridge. The system may further include a pin fluidly connecting the rocker arm to the button and having an elongated cylindrical shaft with a first open end inside the rocker arm and a second end inside the button. The pin may also have a head connected to and a reservoir formed in the elongated cylindrical shaft. The pin may further have passages extending from the bore of the rocker arm to the reservoir, and s passage extending from the reservoir through the head.Type: GrantFiled: March 18, 2015Date of Patent: December 20, 2016Assignee: Caterpillar Inc.Inventors: Charles F. Coffey, Edwin H. Langewisch, Ashwin A. Hattiangadi, David A. Cyborski, John S. Pipis, Jr., Kevin D. Yoder
