- In this the pistons consisted of two cog wheels, their leaves intermeshing, and rotated in an elliptical shaped chamber. William Henry Doolittle. Inventions in the Century.
- It was also found desirable to employ two engines instead of one, the pistons being made to rise and descend alternately. Frederick C. Bakewell. Great Facts.
- When the gun is fired, the recoil causes it to slide back, carrying the pistons, and the recoil is checked by the resistance of the glycerine traveling through an opening past the pistons. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
- The cylinders and pistons were enclosed within the fire box in the rear. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
- Within are pistons, so connected that those in the lower and upper cylinders move together. Frederick C. Bakewell. Great Facts.
- The consequent friction increased the loss of power, and the difficulty of lubricating the pistons added to the practical objections to the air engine. Frederick C. Bakewell. Great Facts.
