sprocket

While I could still slide the motor and motor bracket around, I put the chain over both the sprocket and the motor.

If your batteries don’t have enough energy to move the sprockets fast enough for playback, they certainly won’t be able to skip songs quickly.

Shortly after that hour I looked at the sledge-meter and found that it had ceased working; the sprocket had been knocked off.

Can my invention be made to do better work by putting in gears in place of that sprocket chain?

I tell Polly that Four Oaks is a sprocket-wheel for maids, with two links of an endless chain always on top.

When the chain has been pulled through it may be hooked and adjusted to lower sprocket, and tightened up by screws at top.

The net handle must have broken, and a piece of it has become wedged in the sprocket chain that operates the propeller.
