Abstract: A variable leverage cranking assembly for trailer jacks. The assembly having a housing, an extender assembly, and an attachment assembly. The extender assembly telescopically disposed within the housing such that a distance between a first rotatable handle disposed on the housing and a second rotatable handle disposed on the extender assembly can be telescopically varied so as to change the leverage transmitted to a trailer jack via the attachment assembly connected to the housing. Furthermore, the telescopic adjustment between the housing and extender assembly can be locked into position via a spring loaded latching assembly disposed on the housing and holes disposed in the extender assembly.

Abstract: The present invention relates, in general, to a punch assembly and methods of using same and, more particularly, to a punch assembly that is capable of accurately and repeatedly measuring an intersecting point at which a hold or indentation can be put in a sheet of material such as, but not by way of limitation, a sheet of metal.

Abstract: The present invention relates generally to a jack stand and methods of making and using same. In particular, but not by way of limitation, the present invention relates to a jack stand having (1) a targeting assembly for use in aligning the jack stand when attached to a trailer with an operating vehicle; and (2) means for automatically moving the foot assembly of the jack stand from a ground engaging configuration to an upright stored configuration.

Abstract: The present invention relates to a safe and secure trailer hitch for use with a towing vehicle. More particularly, but not by way of limitation, the present invention relates to an optical guiding trailer hitch device which allows an operator of a towing vehicle to easily, accurately, and safely attach a trailer to the towing vehicle. Additionally, the optical guiding trailer hitch device may further include an assembly for aligning the trailer in a horizontal plane relative to the towing vehicle. The present invention in conjunction with a trailer may be used for the transportation of a boat, a camper, a mobile home, or any such object which may be moved from one place to another place using a trailer and a towing vehicle.

Abstract: A jack stand or support for a trailer jack having a vertically extending housing and an extensible plunger telescopically contained by the depending end of the jack housing includes an upright member mounted on a flat base. A sleeve-like socket, in which the upper end of the upright member is telescopically received, is secured to the depending end of the jack plunger. The socket member is pivotally mounted in elongated slots formed in parallel strap members secured to the upright member for a lateral pivoting movement of the jack stand to a stored travel position by rollers on the strap members contacting forwardly and rearwardly extending arcuate tracks, mounted on the jack housing, during retracting movement of the plunger into the housing.

Abstract: A trailer hitch guide for assisting the operator of a towing vehicle in positioning the trailer hitch components in cooperative coupling relation includes a translucent light beam receiving target member mounted on the towing vehicle for interrupting light beams from a lamp mounted on the trailer tongue. The position of focused lamp rays on a preselected portion of the target member indicates to the operator when the hitch components are in cooperative coupling position.
