Those are solid rubber wheels, with chains... that had to be HARSH on the driver!
The bell was a bronze replica of the Liberty Bell of the revolutionary war fame
Known also as the “Women's Liberty Bell,” or the “Suffrage Bell,” the Justice Bell was made the same size and shape of the Liberty Bell, but with two significant differences:
to the inscription on the original, “Proclaim liberty throughout all the land unto all the inhabitants thereof,” Katharine added, “Establish justice and secure the blessings of liberty” to emphasize her own mission.
In addition, Katharine arranged for the bell's clapper to be chained to the side of the bell. It was silenced—just like women's political voices were then—and would remain silent until women were granted their right to vote.
After the attempt to get the vote in Pennsylvania failed, Katherine turned her attention to the national stage, and continued to tour with the Bell over the next several years at political rallies and events all the way from Illinois to Washington, DC.
