Abstract: A sprayer boom mount may include a support column configured to be mounted on a vehicle. The sprayer boom mount may include a forward extending latch bar and a boom mounting bracket pivotably attached to the support column and spaced from the forward extending latch bar. A sprayer boom may be mounted to the boom mounting bracket. The boom mounting bracket may be latched in a selected pivotable position by placing a latch pin through aligned holes included in the forward extending latch bar and the boom mounting bracket. Thus, the sprayer boom's spray direction can be adjusted to a preferred position.

Abstract: A ramp includes first and second longitudinal support beams extending in a longitudinal direction, each of the longitudinal support beams being formed from bent aluminum sheet material and having a cross-sectional shape including a laterally outer side wall, a top wall, a bottom wall and a laterally inner longitudinal opening between the top wall and the bottom wall. A plurality of support rungs extend transversely between the support beams, each of the support rungs being formed from bent aluminum sheet material and having a cross-sectional shape including an upper support surface and first and second side walls extending downward from opposite edges of the upper support surface, each of the rungs having first and second ends received through the laterally inner longitudinal openings of the support beams. Each of the support rungs is welded to each of the first and second longitudinal support beams.

Abstract: A trailer jack comprising a vertically oriented vertically extendible jack and a mounting flange located on the jack. The mounting flange includes three bolt patterns. Each of the three bolt patterns includes a forward slot and two rear slots defined through the mounting flange. Each slot includes a longitudinal axis. The longitudinal axes of the slots of any single bolt pattern intersect at a bolt pattern axis that is closer to the forward slot than the rear slots. The longitudinal axes of the forward slots intersect at a central axis. The central axis is offset from each of the three bolt pattern axes. The rear slots of any of the bolt patterns are non-radial with regard to the central axis. The forward slot of any of the bolt patterns are radial with regard to the central axis.

Abstract: A light bar assembly may include a light bar housing having a bar length. The light bar housing may include a plurality of fins projecting from the light bar housing. The light bar housing may further include a plurality of fin gaps. Each fin gap may be disposed between adjacent respective fins. Each fin gap may also have a gap length running longitudinally along a majority of the bar length of the light bar housing. The light bar assembly may also include a wind shield disposed on the light bar housing. The wind shield may cover some, but not all, of the fin gaps along a majority of each respective gap length.

Abstract: A lighting apparatus includes a frame having a straight central portion and first and second curved end portions, a plurality of spot light sources mounted on the straight central portion and aligned parallel to each other, and a plurality of diffuse light sources may be mounted on each of the curved end portions.

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.
