A high visibility coupler for front end loader implements that is selectively mountable to the extendable arms of a front end loader and is attachable to implements, such as a fork. The structure of the coupler is such that it has a plurality of parallel lift ribs that are perpendicularly interconnected by cross ribs to form an open lattice type structure, thereby allowing the operator of the front end loader to easily see and manipulate the fork or other attachment, so that the object to be picked up can be easily and safely engaged. One embodiment of the high visibility coupler for front end loaders includes a male master, a carriage and a movable implement such as a fork. The male master includes a plurality of parallel lift ribs that are perpendicularly interconnected by cross members to form an opening wherein the male master is received and carried by lift pistons operative with the lifting arms. The male master carries a carriage which has openings aligned with the opening of the male master. The carriage also has parallel ribs that are perpendicularly interconnected by cross tubes to form an open lattice type structure. One of the ribs includes a hook notch and carriage hole so that the carriage can be carried and secured to the male master. The carriage also includes a slide rod which receives a collar of an implement in such a manner that the implement can be adjusted to any desired position. The structure of the alternative embodiment also allows for the easy visualization of objects to be engaged by the implement.

A coupler is provided for implementation on the boom of an excavator and adapted for receiving and coupling an arm or implement. The coupler is pinned to the boom through apertures and a pair of parallel plates. An actuating hydraulic piston is connected to the coupler through holes passing through another pair of plates. Attachment to the arm or implement is achieved by first engagement of a pair of slots with pins on the arm, and subsequent engagement of other slots with another pair of pins. The last mentioned slots have associated therewith a cam locking plate which closes the slot upon the pins to prevent removal.

Boom/arm coupler for excavator

A coupler is provided for implementation with front end loaders. A male face plate is connected to the arms of the front end loader, having spring biased and hydraulically released cams on the back surface thereof and maintained in juxtaposition to an aperture passing through the base plate. A female coupler portion is attached to an appropriate implement. The female coupler portion includes a pair of ribs having hooks at the top thereof for engaging the bridge pins of the male portion, and legs having cam pins extending from bottom portions of the ribs. The legs and cam pins pass through the aperture of the faced plate to make locking engagement with the cams.

Cam locking coupler system

A plurality of cylindrical, equiangularly spaced elastomeric isolator members are assembled axially between a drive plate fixed to an engine flywheel and a driven plate fixed to a transmission input shaft. The isolation members are resilient and yieldably resist relative rotation between the drive and driven plates at a first spring rate when torque loads are in a low range. When the torque load reaches an upper value of the low range, a pair of snubber members respectively mounted on the drive and driven plates are engaged by the flexed isolator members and support the latter such that torsional loads in a range higher than the low range will be yieldably resisted by the isolator members at a second spring rate higher than the first spring rate.
