  • Patent number: 9840819
    Abstract: Embodiments of the invention provide an interlock arrangement with a blocking feature and a locking feature secured to an interlock member. The interlock member can move between first and second interlock orientations. With the interlock member in the first interlock orientation, the blocking feature can prevent attachment of a power conduit to a power connection, such that the motor is not enabled to power a powered device, and the first locking feature can allow a first gate to open in order to provide access to the powered device. With the interlock member in the second interlock orientation, the blocking feature can allow attachment of the power conduit to the power connection, such that the motor is enabled to power the powered device, and the first locking feature can prevent the first gate from opening such that the first gate obstructs access to the powered device.

    Abstract: A single lever blade control apparatus for bulldozers that is capable of operating in three mutually perpendicular planes to activate three independent hydraulic valves controlling a bulldozer blade: up/down, tilt and angle. Movement of the bulldozer blade in an up/down motion is accomplished by the operator by pushing the single lever apparatus in the X direction, the X direction corresponding to the longitudinal axis of the bulldozer. Movement of the bulldozer blade in the tilt direction is accomplished by the operator pushing the single lever apparatus in the Y direction. Angling the bulldozer blade is accomplished by the operator rotating the handle of the single lever apparatus about the Z axis. The invention works with all variations of hydraulic valve placement.

  • Patent number: 4680880
    Abstract: A snow plow, designed to fit on small vehicles, is disclosed. The plow has a single point connection to the vehicle. A novel yoke mounting scheme is also disclosed, which enables the blade to be angled. The plow is operated by a pneumatic means, controlled from within the vehicle. All operating connections to the vehicle are made through a single power cord. All pneumatic lines are self contained within the plow, thereby eliminating the need for air hoses to be connected or installed on the vehicle. The plow has an upstop device that is used to block upward travel of the plow. The upstop is used to prevent the plow from obscuring the headlights of the vehicle. An uplock is also provided which acts to lock the plow blade in an non-operating position when the plow is not needed, thereby preventing the possibility of the blade dropping to the road and causing an accident. The plow is designed to be removed quickly and easily from the vehicle for storage.

    Abstract: A mechanism is disclosed for automatically laterally shifting a dozer blade to the exposed side of the tractor as the blade is angled to thereby keep the blade in front of the tractor and permit the use of a blade which is shorter than conventional angling blades. The lateral shift mechanism includes a slide plate support connected by a universal joint to the center bight portion of a C-shaped frame. The blade is mounted to the slide plate support by guide plates that permit the blade to slidably move along the longitudinal extent of the slide plate support when the blade is angled. A vertical mast support structure at the center of the bight portion of the frame mounts one end of extensible piston-cylinders used for angling, tilting, and pitching the slide plate support and blade. A slider bar is connected between the vertical mast and the blade for laterally shifting the blade when it is angled.
