1507) At a guess, it is a coin collection box for early trolley cars or buses. The driver/conductor could lift it out and carry it to the office for official counting, and I'll bet that it has a mechanical counter inside.I do wonder how it was opened to remove the coins.
And the coin slot and plunger look as though they came from game machines -- pinball or the like.
1508) Wine bottle opener. You stick the needle through the cork, then pump the handle to build up pressure in the bottle to force the cork out.1509) Looks like a primitive relative to a Johnson bar for moving heavy machine tools.
Maybe for moving a railroad car an inch at a time?
1510) At a guess, it is to clamp on the hooves of horses to keep them from sinking in overly soft ground or mud.It does look potentially painful, however.
1511) Looks like a primitive speed loader, for loading all six cartridges into a revolver cylinder at once.The spring in the center of the back puzzles me a bit, however.
1512) Clamps on round rod, or perhaps on an overlap of two wire cables to form an eye.Now to see what others have suggested.
Enjoy, DoN.
