  • Patent number: 12134869
    Abstract: An adaptable and removable winch mount is an adapter that connects to an existing snowplow mount on a pickup truck which in turn allows for the attachment of a winch mount. The mount provides a seamless transition between the snowplow mount and the winch mount. The invention consists of two parallel steel plates that each connect to the plow mount via a pin lot and locking hole each. The plates are then interconnected by two steel tubes with a receiver hitch in the middle. The overall width of the invention is approximately thirty-three inches. This allows a standard hitch mount winch to then be attached to the invention in a typical manner.

  • Patent number: 4432169
    Abstract: The glassware etching apparatus etches glassware or other workpieces with abrasive grit which is entrained in an air flow. The etching apparatus includes a cabinet having a work surface, a transparent shield over the work surface and upper and lower supporting shelves below the work surface. A foamed plastic workholder for receiving the workpiece to be etched is mounted on the work surface. A venturi structure for entraining abrasive grit in the air flow is mounted in alignment with the workholder on the upper shelf. A linear tube extending from the venturi structure directs the air flow with entrained grit toward the workholder. The air flow is generated by vacuum cleaner-type motor-impellers in fluid connection with the venturi structure. Grit rebounding from the workpiece is trapped by a fabric filter which extends from the bottom of the work surface around the directing tube.
