  • Patent number: 10605450
    Abstract: The boiler cleaning apparatus and method provides for cleaning the exterior surfaces of a heat exchanger. The apparatus and method include tools and steps, respectively, for temporarily spreading tubes and holding open the tubes to gain access to tube lanes. Once access to a lane is attained, a nozzle assembly having an outlet for blowing high velocity cleaning fluid is selected from a group of nozzle assemblies. The selected nozzle assembly will have an outlet for blowing fluid in a direction that effectively cleans the tubes adjacent the opened lane. After the tubes are cleaned the tool for holding the lane opened is removed and the process is repeated for another lane.

  • Patent number: 10464192
    Abstract: One example of the present disclosure relates to a method of applying torque to an object, which threadably engages a part. The torque is applied with a wrench, comprising a first handle, a second handle, a planetary gear mechanism, a drive that comprises an internal gear and an external gear, and a first pawl, movably coupled to the first handle and biased to contact the external gear of the drive. When the drive is coupled to the object, the method comprises transmitting an input torque to the drive by rotating at least one of the first handle and the second handle relative to the part. The first pawl is movable between a first position and a second position relative to the first handle may or may not operatively engage the external gear of the drive.

  • Patent number: 10393366
    Abstract: A torque wrench provided with illumination structure and indicated graduations includes a tubular body bored with an insert hole and an illumination hole. The tubular body is provided therein with a graduated ring having its outer circumferential wall provided with a graduation marked portion, with an interval kept between the graduation marked portion and the inner tube wall of the tubular body. A lens is disposed at a location corresponding to the insert hole, and a light-emitting element is installed at a location corresponding to the illumination hole. Thus, light emitted by the light-emitting element will first illuminate the graduation marked portion and thereafter the reflected light of the graduation marked portion will pass through the insert hole and pass out the lens, enabling a user to clearly read the graduation marked portion.

  • Patent number: 10335930
    Abstract: A torque wrench having a handle and an output shaft is disclosed. The output shaft may be constrained to turn only unidirectionally due to a ratchet. Rotation of the output shaft may be permanently disabled by an internal mechanism. Torque imposed on the output shaft may be limited by a torque responsive cam clutch. The handle forms or is part of an enclosure enclosing internal components such as the ratchet, the internal disablement mechanism, and the torque responsive cam clutch. A seal between the body and the output shaft prevents ingress and egress of lubricants and contamination between the inside of the body and the output shaft.
