A trailer hitch system for improving the speed and safety of attaching the trailer to a tow vehicle. The hitch may include a shank that may be attached to the trailer through a ball hitch. A receiver may be provided on the tow vehicle such that attachment of the trailer to the tow vehicle may be accomplished by introducing the shank into the receiver when the tow vehicle is backed to the trailer. A funnel shaped guide member may be provided to facilitate aligning the shank with the receiver. Also, friction reducing rollers may be used with the shank or the receiver. Moreover, a height adjustment and visual guidance system may be included to facilitate connecting the trailer to the tow vehicle.

Trailer hitch system

An omnibus process of pulping and bleaching lignocellulosic materials in which a charge of a lignocellulosic material is biopulped and/or water extracted prior to pulping and bleaching. The lignocellulosic material may be mechanically pulped and bleached in the presence of an enzyme that breaks lignin-carbohydrate complexes.

Methods of producing a paper product

A trailer hitch jack for rapidly raising and lowering the tongue of a trailer.

Retractable jack foot

An omnibus process of pulping and bleaching lignocellulosic materials in which a charge of a lignocellulosic material is biopulped and/or water extracted prior to pulping and bleaching. The lignocellulosic material may be mechanically pulped and bleached in the presence of an enzyme that breaks lignin-carbohydrate complexes. The aqueous extract in embodiments including a water extract step is separated into acetic acid and hemicellulose sugar aqueous solutions.

Product and processes from an integrated forest biorefinery

An apparatus for tensioning spring arms used in conjunction with a weight distribution hitch. The apparatus may comprise a mechanical linkage that may be operable to multiply an input force provided by a jack to an output force of sufficient magnitude to tension the spring arms. The mechanical linkage may comprise a pair of rigid arms that are linked to a support post of a trailer jack. The pair of rigid arms may automatically be raised in conjunction with the support post being operated from a lowered position to a raised position. The rigid arms may exert a force on a cross-piece member extending between the spring arms. Alternatively, the mechanical linkage may comprise a flexible member for placing the spring arms under tension.

Apparatus for leveling a trailer and dampening sway

A wheel chock system for preventing movement of one or more wheels. The system may include a pair of chocks for clamping onto one or more wheels. The chocks may be connected through a linkage mechanism that can be rotated to draw the chocks together or move the chocks further apart. A handle may be attached to the linkage mechanism for moving the chock system from a blocking position to a released position. The handle may be configured to stand upright such that the chock system can be installed and removed by a user in a standing position without the need to bend or crouch. One embodiment of the chock system may be attachable to two different wheels in a tandem wheel arrangement, whereas another embodiment of the chock system may be configured to clamp onto a single wheel.

Over-center clamping wheel chocks

A retractable jack foot for a trailer hitch jack is disclosed, for rapidly raising and lowering the tongue of a trailer. The retractable jack foot solves multiple prior art problems discussed above in the 'Description of Related Art,' such as: trailer hitch jacks not being long enough to reach the ground and still lift the trailer to a sufficient height (small distance travel); the laborious, time-consuming practice of cranking a trailer hitch jack all the way to the ground before finally causing lift in the trailer. In both cases, blocks of wood or other spacers are sometimes used to reduce the travel of the jack. The retractable jack foot of the present disclosure, solves those problems, by providing a 'built in' block, or foot, pivotally attached to the bottom of the trailer hitch jack. The jack foot can be rotated into and out of position as desired, to quickly lengthen or shorten the jack.

Moreover, a height adjustment and visual guidance system may be included to facilitate connecting the trailer to the tow vehicle. The shank includes a stop in a fixed position for limiting the depth the shank extends within the receiver.

An improved hitch pin system for improving the speed and safety of attaching a receiver insert into a receiver on a tow vehicle.

Apparatuses are disclosed where in a lever binder may include an adjuster that when manipulated adjusts the binding length of the lever binder. In various embodiments, a lever binder is disclosed including an automatic latching mechanism to help resist undesired movement of a lever from a binding position.

Adjustable lever load binder

Embodiments of the present invention provide a cargo guard that is readily coupled to and/or removed from a binding strap, and further readily adapted to be repositioned with respect to the strap. The cargo guard may include one or more segments and/or one or more retainers.
