In front of the Cooke Locomotive factory in Paterson, N.J., is one of the prototype William C. Oastler steamrollers produced in 1899. These machines featured steam-jacketed cylinders and specially patented drawbars and spring scrapers. While the roller featured does not show a water tank beneath the boiler, Oastler rollers could be equipped with such tanks by special order. This view is taken from the Oastler Steam Road Roller catalog of that year.
