...fix the end of the device (when needed mount the extension pieces together) on the external part of the examined surface such as a cylinder, gearbox, carb, differential, mechanical parts, pipes and so on. Put the membrane to your ear and diagnose by simply listening; defects such as oil deficiency, loose bolts, screws and so on with certainty. In danger of electrocution use the red insulated sound finder that neutralizes electricity. When checking for pipe defects hold the device to the raised examinated part such as hydrants and so on. It will work even through brick walls, bitumen and soil to diagnose the defect.

1967. An ice cube crusher, the patent states:

...it is proposed to arrange the containers telescopically relative to each other and to provide a plurality of pointed elements mounted on the top and base wall of the containers and directed towards each other for cracking a piece of ice placed within the containers when they are forced together.

1957. A halibut hook

...it was held down by a stone weight so it floated at the bottom of the sea.

The Pacific halibut looks like a fish swimming on its side along the bottom of the sea, except both eyes are on the upper side. It belongs to the flounder family and is by far the largest of all flatfish. Although a halibut can weigh up to 600 pounds, the specially engineered Tlingit hook was designed to catch a fish no larger than a man could haul into his canoe.

1962. A stand that was used to bundle rolls of wallpaper in preparation for shipping. A paper covering material (possibly cardboard) was placed in the form. Then printed rolls of wallpaper were placed on the covering and the covering was wrapped around the bundle. The leather straps were also wrapped around the bundle and tightened with the crank to compress the rolls. Then string or tape was wrapped around to secure the bundle, ready for shipping. The stand is open in the middle so string could be put around the package and then lifted out of the stand.
