Patent number: 11654715Abstract: Disclosed are systems and methods for reducing friction on a brake arm of a caster wheel brake. A washer can be positioned between the brake arm and the support arm to reduce friction in this area. Lubricant can also be provided between the brake arm and the support arm, and also between the brake arm and the brake cam, to reduce the friction in these areas. The presently disclosed embodiments therefore allow less force to actuate the brake arm as compared to prior art caster wheels.Type: GrantFiled: April 13, 2018Date of Patent: May 23, 2023Assignee: Snap-on IncorporatedInventors: David A. Doerflinger, William T. Sharp

Patent number: 11293630Abstract: An interactive tool storage system may include an enclosure with a storage bin and a sensor system configured to detect the interaction of a person with the storage unit. A data acquisition system may collect data from a sensor in the sensor system. The system may include a power module, electric circuit, and data circuit to operably couple the system components. A network interface may enable the input and output of electrical power and data while a data storage system with a writeable memory may collect and record sensor inputs and system outputs. The system may include a non-transitory machine readable memory to store program instructions and a data processor configured to read/write data to the system memory, manipulate data and perform logical operations, interact with sensor system and networked devices; and present a user interface through which the user may interact with the system.Type: GrantFiled: November 14, 2019Date of Patent: April 5, 2022Assignee: Snap-on IncorporatedInventors: Rupak Kumar Paul, Ottoleo Kuter-Arnebeck, David A. Doerflinger, Benjamin T. Schulz, Nicholas H. Weir

Patent number: 11149477Abstract: Disclosed are latches with pre-molded or pre-assembled fasteners. The latch fastener can include a threaded portion and a lead in portion that is longer than the threaded portion. During installation of the latch, the lead in portion can be inserted into a cavity of a drawer to help align the latch against the cavity during installation. The built-in fastener frees one hand of the user during installation and the additional length of the lead in allows an easier alignment of the latch during installation.Type: GrantFiled: June 28, 2017Date of Patent: October 19, 2021Assignee: SNAP-ON INCORPORATEDInventor: David A. Doerflinger

Patent number: 10308068Abstract: A caster with an elastic member that absorbs impact forces during use. The elastic member can be placed between first and second portions pivotable with respect to each other about a pin. The elastic member can absorb impact forces between the first and second portions when in use. The elastic member can further include grooves that allow portions of the elastic member adjacent the grooves to flow into the grooves during impact, further absorbing impact forces.Type: GrantFiled: October 25, 2017Date of Patent: June 4, 2019Assignee: Snap-on IncorporatedInventors: William T. Sharp, David A. Doerflinger
