Creskol's photos of an intact "cast-iron bell toy" show that his guess seems to be correct.
My guess that "it appears to be" a child's Gyroscope toy was based on the very-distinctive "skeletal 6-pointed star-inside-a-circle" form of the wheel on Randy769's find. I've never seen that very-distinctively elaborate form on anything but a Tedco (brand) Gyroscope-toy. See the photo below.
Randy769's find causes me to wonder if perhaps a toy manufacturer or a toy repairman used some surplus Gyroscope-toy wheels as the bell-toy's wheels.
