Abstract: A wrench apparatus is provided for applying torsion to a T-shape cross-section fence post. A wrench head has a lateral opening so that the wrench head can be placed laterally about the T-shape cross-section post. The wrench head includes first, second and third engagement surfaces arranged to simultaneously engage the three flanges of the fence post so that a torsional load can be simultaneously applied to all three flanges of the fence post.

Abstract: A lighting apparatus for mounting on a vehicle cab includes a frame having a straight central portion and first and second curved end portions. A plurality of spot light sources may be mounted on the straight central portion and aligned parallel to each other to provide a deeply penetrating uniform wide central path of illumination. A plurality of diffuse light sources may be mounted on each of the curved end portions to provide less penetrating but more widely dispersed paths of illumination to each side of the central path of illumination.

Abstract: An automatic animal watering apparatus includes a dish having an automatic watering valve disposed therein. When the valve is first closed, a water level in the dish is at a maximum level, and a hydraulic source pressure acts only across a smaller cross-sectional area of a valve seat which is closed by the valve, thus requiring only a first lower buoyancy force acting on a valve actuator float to maintain the valve closed. The water level can then drop from the maximum water level to a minimum water level before the hydraulic force action on the valve overcomes the first lower buoyancy force on the actuator float and reopens the valve. Then when the valve opens, the hydraulic source pressure acts against a larger cross-sectional area of the valve, thus requiring the buoyancy forces acting on the float to rise to a second higher buoyancy force to reclose the valve.

Abstract: A multi-use trailer hitch configured to allow a single hitch to be used for multiple trailer couplers. The hitch includes a ball and pin member attached to the yoke so that the hitch can couple with a Lunette eye ring coupler and a ball hitch coupler. The ball and pin member is designed to fit on the yoke and be easily secured with a retainer pin.

Abstract: A cart may comprise a body, an axle having an axis of rotation, at least one wheel, a forward support, and a rear support. The forward support may include a forward support hinged end, and a forward support free end, the forward support hingedly connected to the body at the forward support hinged end to pivot about a forward support axis. The rear support may include a rear support hinged end, and a rear support free end, the rear support hingedly connected to the body at the rear support hinged end to pivot about a rear support axis. The forward support free end may be configured to selectively connect to the rear support at the rear support free end by the axle to rotatably support the wheel, and the axis of rotation of the axle may be parallel to each of the forward support axis and the rear support axis.

Abstract: A light assembly for use in a work area that is mountable, portable, can be powered by moveable work equipment, and is capable of providing light necessary to adequately illuminate a work area so that work tasks can be completed. The mountable light assembly includes a housing containing a light source for illuminating a work area and a hanger for hanging the light assembly. The mountable light assembly may include an extension cord designed to be held in a storage compartment and pivotable wing housings containing wing light sources. For example, the light assembly may be designed to mount on the tailgate of a pickup truck and to draw power from a trailer power outlet.

Abstract: A drawbar apparatus for a cart, wagon or trailer. The drawbar apparatus includes a shaft having a first end suitable for connection to a cart, and a second end including a hitch coupling. The drawbar includes a handle member having a handle first end and a handle second end. The handle first end is pivotally connected to the shaft, and the handle second end includes a grip or gripping region. The handle member is selectively pivotal between a first position and a second position, the hitch coupling extending distally beyond the handle member in the first position, and the handle member extending distally beyond the hitch coupling in the second position. Some embodiments further include a lock configured to selectively secure the handle member when the handle member is in the first position and the second position.

Abstract: The assembly applies an apex filler to the outer circumferential surface of an annular bead ring. The apex filler applying assembly incorporates an apex filler applicator that is preferably operable in conjunction with a plurality of server mechanisms. One server mechanism is a conveyor that receives a bead ring. A locator operates in conjunction with the conveyor to position the annular bead ring precisely on the conveyor so that it may be engaged by a transfer mechanism. The transfer mechanism removes the bead ring from the conveyor and mounts it on a chuck turret assembly. A chuck head in the chuck turret assembly engages the bead ring and accurately positions the bead ring relative to applying rollers in the apex filler applicator, in which position the apex filler--which has been directed from an extruder through an orienting mechanism, into an in-feed mechanism and severed to length by an in-flight guillotine cutter--is applied to the annular bead ring.
