Abstract: A mechanical lifting device is the subject of the present invention. The device includes a framework which may be easily collapsed or assembled and comprises a plurality of tubular pieces which are held in place by bolts utilized as set screws. Two upright spaced apart frame sections support two spaced apart support bars and a gear rack and lever are employed to effect movement of the support bars. A platform may be mounted on the support bars to provide a scaffold. The platform may also be removed and the support bars positioned over a load to lift it straight upwardly.

Abstract: A device for protecting a padlock from tampering. The device consists of two separate plate sections which wrap around respective posts of a gate to be padlocked and are secured onto the posts via nut and bolt assemblies. Extending outwardly on the front of each plate section is a semicircular shield which, when the two plates are brought together, will meet the shield on the companion plate and encircle the padlock. On the back side of one plate section is a housing which is also secured to the plate section via a nut and bolt assembly and which receives the shackle of a padlock. To lock the gate (or other similar opening), the padlock shackle is passed through an opening in the plate section, into the housing, and through an opening in the companion plate section. An alternative form of the invention utilizes hinged latch plates secured to the flat portion of a solid door instead of the plate sections of the former embodiment.
