Spring Or Weight Return Patents (Class 74/140)
  • Patent number: 6900610
    Abstract: The invention is a system for controlling the position of a movable member moved by a prime mover by monitoring the position of the movable member; generating position information based upon this monitoring; and controlling the prime mover based upon the position information by providing a counter force to the movable member substantially equal to an opposing force opposing the movement of the movable member. The invention may include a movable member, such as a ram used for fastening a terminal to a wire; a spring; a DC planetary gear motor for providing a force to the movable member opposing the spring; a position detector, such as an linear voltage displacement transducer, to detect the position of the movable member and generate position information; and a controller, which may include a logic board or microprocessor and memory, for controlling the force from the motor in response to the position information.

  • Patent number: 6536396
    Abstract: A starting device has a strip connected to a pulley for a pull start mechanism. The strip is composed of a high performance plastic and is provided with an integral handle. A connection means connects the strip to the pulley on its distal end. The strip fits neatly in a coil around a pulley hub. It lays flat during storage and exerts substantially no lateral pressure against the walls of the pulley. With this construction, the strip does not fray and affords a storing mechanism that is cleaner than a conventional rope system. The starting device has few parts and is easy to assemble. It is lightweight, inexpensive to construct and facilitates starting in an efficient, reliable manner.

  • Patent number: 6244233
    Abstract: A pull-down engine starter has a pull-down line (1) that is attachable to a takeoff line (15) or directly to a rewind-starter wheel (14) and pulley-routed to a suspension pulley wheel (6, 25) from which a handle end of the pull-down line is suspended to conveniently grasping proximity to a user position such as a driver seat (8). For go-carts (4) and other rider-operated vehicles (12) with engines (3) having rewind starters (2), the user position is a driver's seat or a machine-operator position on the vehicles. For walk-behind machines (23) and other non-ride machines such as a generator set (24) with rewind-starter engines, the user position is generally lateral to the engine. Singular-suspension pulley wheels (25) are provided for singular-wheel pull-start lines (22) on head-high pull-down anchors (26) and waist-high pull-down anchors (27).

  • Patent number: 5253540
    Abstract: A device for pulling the starter cord of a lawn mower engine utilizes a pulling cable disposed about upper and lower pulleys on a vertical post. The upper extremity of the pulling cable is attached to a lever pivotally joined to the vertical post. Downward movement of the lever causes the starter cord to be pulled horizontally.

  • Patent number: 5176582
    Abstract: A chain guide is provided for the otherwise unsupported upper run of the endless roller chain of a motor-driven garage door operator. With the chain loop in a vertical plane, the chain guide takes the form of a trough having at its bottom an upstanding central ridge which supports the chain by its rollers and with the links clear of contact with the floor and sides of the trough. The chain guide is supported indirectly by the trackage of the door operator, being mounted upon the fixed rail spacer of one form and carried upon the movable trolley of the other.

  • Patent number: 5174166
    Abstract: A step starter for attachment to devices having small internal combustion engines of up to 15 horsepower or more having recoil-type starters includes a vertical track formed from channel stock. A trolley having a foot pedal extending therefrom is disposed in the track. A distal end of the engine starter pull cord is attached to the trolley. An operator steps on the pedal and depresses the pedal downward thereby operating the recoil starter. The track includes a mounting bracket formed to permit attachment of the step starter to a desired device.

  • Patent number: 4257367
    Abstract: A rope for actuating a recoil starter is trained about a movable pulley outside a main body of the recoil starter, and the movable pulley is rotatably supported by a swing arm or a handle. By moving the swing arm in swinging movement or pulling the handle, the movable pulley can be moved to thereby pull the rope out of the main body of the recoil starter to start the engine. By virtue of the action of the movable pulley, the distance covered by the movement of the swing arm or the handle is smaller than the length of the portion of the rope paid out of the main body of the recoil starter to actuate the recoil starter. At least one further pulley may be provided for guiding the rope in its movement, and a manually operated handle may be additionally attached to the rope. Pulling of the rope automatically makes it possible to actuate an auxiliary engine starting means.

  • Patent number: 4109538
    Abstract: A starter bracket that is mountable on a part of the handle frame of a machine such as a lawn mower which has a pull-cord starting device. The bracket has an extensible post carried by a clamp which can be positioned on the frame so that the post extends downwardly into contact with the surface on which the mower stands. An extension cable passes over a guide in the clamp and has means on one end for coupling the cable to the handle on the pull-cord and a stirrup or foot pedal on the other end for engagement by the user's hand or foot. The post can be collapsed when not in use and swung around the clamp to a storage position. A recoil spring may be engaged with the cable or stirrup for assisting the starting device in restoring the pull-cord and cable to retracted positions. A preferred embodiment also has a motion multiplying device by which the pull cord is moved a distance greater than the distance of movement of the stirrup.
