It is a two-wheeled carriage made entirely of iron, except the pole, which is of oak. The axle-tree is arched to make it stronger, and connected with the pole by strong wrought iron straps and braces. In the rear of the axle a projection is welded to receive the end of a strong hook. The end of the pole terminates in a ferule and an eye. The eye is for the purpose of attaching to the cart when necessary, a limber or a horse.
88. How great weights can be transported by this cart?
It should not be used with heavier weights than about 4000 lbs., but in case of necessity a 24 or 32-pd. gun may be transported on it. For heavier guns or material, the large sling-cart drawn by horses or oxen should be used.
89. What is the field and siege gin and its use?
It consists, like all gins, of two legs and a pry-pole, a windlass, sheaves, pulleys, and a fall or rope, and is used for mounting or handling guns, or other heavy bodies, in the field or in the trenches of a siege. The legs are about 14½ feet long and the height of the gun about 12 feet.
90. How does the garrison gin differ from the field and siege gun?
It is heavier and stronger, as it is used for mounting heavier guns, and has not to be transported like the other with an army in the field. The legs are longer and the gin higher than the other.
91. Describe the casemate gin.
It does not differ from the garrison gin except in its height (which is about that of the field and siege gin) and the thickness and strength of the parts.
