The forward panel is perpendicular to the base and defines objective sight elements inwardly adjacent each end portion. The rearward panel is parallel to the forward panel and defines ocular sight elements inwardly adjacent each end portion. A sight line passing through the aligned first ocular sight element and the first objective sight element is intersected by a sight line passing through the second ocular sight element and the second objective sight element.

Abstract: A portable ventilator for removing deleterious gasses from a welding site provides a funnel-like collection head structurally carried by an electrically non-conductive rigid dispersement tube carrying a powering structure. The powering structure provides pressurized gas from an external source through an adjustment valve to an input nozzle carried in axial alignment in the channel defined by the dispersement tube spacedly adjacent the joinder of the collection head with the dispersement tube to output pressurized gas toward the distal output end of the dispersement tube.

Abstract: A dispenser for individual strip bandages from a rolled elongate bandage supply having the individual strip bandages releasably interconnected between a pair of cover strips defining chambers about each strip bandage. The dispenser provides a feed spindle carrying the bandage supply that is moved to a cover strip separator adjacent to a delivery slot in a casement. The cover strips are removed from a given strip bandage in the separator and pass along waste courses to motor powered take-up devices which move the bandage supply and disperse the given strip bandage through the delivery slot. At least one cover strip waste course has a tension sensor to sense tension in the associated cover strip to control the take-up device moving the associated cover strip to maintain synchronization of the motion of the pair of cover strips on the take-up devices moving them.

Abstract: A measuring and marking apparatus for firewood includes an upstanding tubular body having a handle, defining a channel to carry an inverted aerosol can of marking material and journaling a measuring wheel having a circumferential length equal to a desired length of firewood. The measuring wheel is journaled between wheel forks carried by and extending from the lower body portion. A protruding dog carried on a face of the measuring wheel engages an actuator carried by the body and communicating with the nozzle of the aerosol can so that each rotation of the measuring wheel causes a dispersal of marking material onto the surface being measured and marked.

Abstract: A nutcracker for simultaneously cracking a plurality of similar nuts in a single discreet operation provides a five sided box-like base defining a chamber having an open top, carrying a rigid bottom plate bottom and defining a slot in the front side extending downwardly to the bottom for nut shell removal. One or more spacers configured to fit within the cracking box chamber above the bottom plate, defining similar medial orifices and having different vertical thicknesses are stacked on the bottom plate to define a cracking chamber having a depth of eighty to ninety percent of the average height of nuts to be cracked. A striker plate having a non-resilient body with peripheral configuration to cover the orifice of the spacer and an upstanding handle manually impacts on the uppermost spacer to crack nuts in the cracking chamber.

Abstract: A recreational vehicle loading and transport platform for pickups provides a base mountable in a pickup box to pivotally carry a transport platform below the upper edges of the pickup box.
