Patent number: 10618779Abstract: A system, apparatus, and methods are configured for cleaning and conditioning handrails. A cleaning pad is curved to approximate the shape of a handrail, and is disposed on an arm. The arm may be mounted on a support structure, allowing it to be rolled up to an escalator handrail and left to do the cleaning while the escalator runs. When mounted, the arm may include a spring or piston to keep the arm in a particular position. A second cleaning pad may be included to dry or polish the handrail, the handrail going first through the cleaning pad and second through the drying pad. The arm may be hand-held, allowing a user to reach up or down steps or an incline. The cleaning pad may be mounted such that it rotates about the arm for storage, maintenance or better reach, such as around bends or corners.Type: GrantFiled: May 14, 2019Date of Patent: April 14, 2020Assignee: Thomsen's Mfg.

Patent number: 8545135Abstract: A test kit for unevenly worn sheave grooves, a tool for regrooving sheave grooves that are found to be unevenly worn, and a method for testing for and maintaining the sheave grooves utilizing the test kit and tool. The test kit includes magnetic standards which adhere to a sheave beneath the portion of the sheave touched by the ropes, facilitating testing without having to unrope the sheave. Unevenly worn sheave grooves are visually ascertained by holding a straightedge adjacent to the magnetic standards. The regrooving tool includes a shank that can be received by a stand set up next to the sheave, a body attached to the shank, and an interchangeable cutting insert received by the body that is inserted in the sheave groove. When the sheave is rotated, the sheave groove is ground by the cutting insert, with each groove being ground sequentially until all grooves are again uniform.Type: GrantFiled: October 17, 2012Date of Patent: October 1, 2013Assignee: Vertical Motion Innovations, LLCInventors: Robert D.

Patent number: 8469155Abstract: A gate below an elevator car which prevents access to an elevator hoistway. The gate slidably mounts behind a toe guard and retracts upwardly if the bottom of the gate encounters a person, object or the floor of the elevator pit during downward travel of the elevator. The gate latches when fully retracted so that it may be out of the way during maintenance. A microswitch is wired into the emergency stop circuit that engages when the gate is latched. A trip wire defining the bottom edge of the gate is also wired into the emergency stop circuit, so that the elevator will stop its downward travel if it encounters an obstruction. Rubber bumpers on the bottom edge of the gate cushion impact to people or objects who happen to be below the elevator car and are struck by the gate during downward elevator movement.Type: GrantFiled: February 16, 2012Date of Patent: June 25, 2013Assignee: Vertical Motion Innovations, LLCInventors: Christian E.
