For first time visitors I recommend this archive for some of my best posts.
2347. Approximately 48" long, take a look at Neatorama for more guesses and a chance to win a T-shirt:
2348. 12" long, submitted by a visitor who would like to find the purpose of this device, text on it reads "Bell & Howell Company Chicago, U.S.A. Standard Cinemachinery":
2349. 5' tall, very heavy, round on one side:
2350. Sent in by a visitor who would like to know if these pliers are for a particular purpose, the ends of the handles each have a different shape for prying as seen in the larger image, text on it says "Changeable Tool":
2351. 11" long, yet another tool that was sent in by a visitor who is looking to identify it:
2352. Give a single word that best describes this construction:
2347. A spar torpedo that was designed to be rammed into the hull of an enemy ship, and then detonated by a line from the torpedo to the submarine. From the CSS H. L. Hunley Civil War Submarine Replica, the original torpedo was detonated when attacking and sinking the Housatonic in 1864, the Hunley itself sank shortly thereafter for unknown reasons.
2348. An old movie projector bulb holder used to isolate the heat of the bulb from the socket so the projectionist could change out blown bulbs in a hurry by giving him a cooler place to grab onto.
2349. A tinsmith's stovepipe anvil:
2350. A combination tool that was made to use several interchangeable heads, patent number 791,917. A photo of this tool in its original box with all the attachments can be seen here under the heading of patent pictures.
2351. A Morse Taper Key for use by a machinist to remove chucks and tooling.
2352. On this web site they refer to it as an abatis, though these structures were also called palisades.
