Abstract: A coupling for a plow comprising a push beam attachable to a front of a vehicle. The push beam has at least one outwardly-extending plate at each end thereof. Each plate has an aperture extending therethrough. A support frame is provided that is attachable to the back side of a plow assembly. The support frame has two spaced-apart plates extending therefrom, each of the plates having an aperture therethrough. The plates are dimensioned to be positioned adjacent the plates on the push beam with the apertures in the plates being aligned. A locking assembly is provided for locking the support frame to the push beam. The locking assembly is comprised of a pair of axially aligned pins biased outwardly away from each other. Each of the pins has an inner end and an outer end. A linkage connects the inner ends of the pins. The linkage has a first position wherein the pins are retracted toward each other along the axis, and a second position wherein the pins extend outwardly away from each other along the axis.

Abstract: A coupler comprised of a coupler housing having a first opening formed therein. The opening has a concave cavity. A cylindrical socket is formed within the housing. A second opening in the housing communicates with the cylindrical socket. A lock ring is provided, the lock ring having a cylindrical portion and an arm portion extending therefrom. The cylindrical portion of the lock ring is disposed within the cylindrical socket in the housing with the arm portion extending from the housing through the second opening. An opening is formed through the cylindrical portion of the lock ring. The cylindrical portion of the lock ring is rotatable in the cylindrical socket wherein the lock ring is movable between a first position wherein the opening in the lock ring is aligned with the concave cavity to allow a tow ball to be inserted into the concave cavity through the opening in the lock ring and a second position wherein the opening is not in alignment with the concave cavity.

Abstract: A tow hitch comprised of an elongated shank of rectangular cross-section. The shank has four side surfaces. A first tow ball of a first dimension is fixedly mounted to a first of the side surfaces. A second tow ball of a second dimension is fixedly mounted to a second of the side surfaces. A third tow ball of a third dimension is fixedly mounted to a third of the side surfaces. The first and the third tow balls are on opposite side surfaces of the shank. A jaw is mounted to the shank for pivotal movement about an axis through the shank. The jaw has a ball-engaging surface, and is movable between a first position wherein the ball-engaging surface engages one of the tow balls and a second position wherein the ball-engaging surface is spaced from one of the tow balls.

Abstract: A one-piece pintle hitch is disclosed. The one-piece hitch utilizes an integral drawbar that may be engaged with a conventional receiver assembly such as installed along the underside of a vehicle. The one-piece pintle hitch avoids the use of prior art mounting plates that bolt to one another. Accordingly, the problems associated with threaded fasteners such as loosening, fracturing, and corrosion, are eliminated. In addition, the one-piece pintle hitch utilizes a unique configuration along its bar portion that results in a significant reduction in weight and materials.

Abstract: In hydraulic or mechanical systems, remote controllers are used to actuate and then control the systems. For instance, in dump vehicles, a controller controls a hydraulic or mechanical actuator that is used to raise and lower the bed during the dumping cycle. A locking safety feature is provided on such a controller to assure that accidental or too rapid of dumping does not occur. This controller provides stops that prohibit additional actuation of the bed absent override. The locking safety feature includes a button within the knob that allows for one-handed operation.

Abstract: An improved apparatus having a bumper-frame assembly suitable for light towing vehicles is disclosed. The invention can be utilized for attaching a pintle hook or receiver hitch to the rear end portion of the towing vehicle.
