The INDUSTRY area of the Museum displays exhibits about the people, the tools, the machinery they used, and the way the two combined to produce Springfield Armory's military weapons from the Nation's earliest days till 1968.
 
The only surviving Blanchard's original duplicating lathe, circa 1822.

In the 1960's the Smithsonian Institution created a very close working replica of this Blanchard lathe. Now displayed there, it is the machine seen in the video.

Original 1822 Blanchard Lathe

Thomas Blanchard's invention of the duplicating lathe, first used at Springfield Armory, was one of the most significant developments in American industrial history. It permitted exact duplication of irregular wooden shapes, such as gun stocks. This was an important step in creating mass production techniques. The original machines relied on water power at the Water Shops. To see a reproduction Blanchard lathe at work, watch the video nearby in the Museum or [see video clips below on our FORGE OF INNOVATION WEBsite!].

This Blanchard lathe is known today as of the "First Generation" Blanchard lathe. It is a technology still in use around the world.
Seen here is the follower wheel that rolls on the surface of the rotating iron musket stock form to direct, through a simple mechanical linkage, the rotating cutter .

Seen here behind the Blanchard lathe are examples of Springfield Armory production machinery from the mid-19th century.
Shown here is the rotating cutter and the musket stock blank in the process of being formed. The last time this machine was used was about the time of the Civil War [1861-65]. It was used at that time for the initial coarse shaping of the lower half, the butt stock end, of the musket.

The working .3-scale model, made possible with a grant in about 2000, was made by Clint Bostock, a fine craftsman. It can actually cut a miniature musket stock about eight inches long.
Included in the exhibit is a working .3-scale model of the Blanchard lathe. Visitors may run it for about 30 seconds by pressing a green start button. It's great fun to figure out for yourself how the gun stock is cut!

POST-MOUNTED DRILL PRESS

This wall-mounted belt-driven machine was one of the commonest types of shop equipment. It could be used for drilling holes in wood or metal. The "Little Giant" machine was made in the late 19th Century by Wells Bros. of Greenfield, Mass.

This improved "Second Generation" model, of the type purchased in New England in the 1850's by the British for the Royal Small Arms Factory at Enfield, England, was designed by Sprinfeld Armory Master Armorer Cyrus Buckland.

BLANCHARD IRREGULAR TURNING LATHE

A later version of Thomas Blanchard's wood-turning lathe, this machine was more efficient and took up less space. The iron frame provided greater support, which permitted more accuracy. This machine remained in use long enough to be converted to electric power.

This mid-19th Century image shows a "Second Generation" Blanchard lathe, like that shown above, in operation. The Museum's example is incomplete.

ENGINE LATHE

This lathe, probably made in the 1850's, was used for cutting screw threads and other metal working. It was typical of machines that would be used in a metal-working shop, but was not especially adapted for gun manufacture.

Lamson, Goodnow & Co., who made this machine, were US contractors during the Civil War for US Model 1861 rifle muskets. They are still in business, then as now, manufacturing fine cutlery.

RIFLING MACHINE

This machine cut spiral grooves into the barrel of a firearm. A bullet traveling in a spiral, like a football, was more accurate. This machine was made by Lamson, Goodnow & Co. in Windsor, Vt., and was used by Smith & Wesson in Springfield for rifling pistol barrels.

BARREL-STRAIGHTENING ANVIL

A barrel-straightener would begin the process of straightening a barrel by laying the barrel across the anvil and striking it sharply with a hammer.

BARREL-STRAIGHTENING MACHINE

After going through the great heat of manufacturing, gun barrels needed to be straightened. A barrel that was not perfectly straight would not be accurate. This type of machine was in use for most of the 20th Century. One may be seen at work in the video located nearby in this Museum.

CHRONOSCOPEFollowing the Civil War, the U.S. military became interested in the scientific study of weapons and projectiles - what is now known as ballistics. Springfield Armory experimented with a number of different chronoscopes - machines to measure the speed of bullets. This particular machine was invented by Captain Schultz of the French Army. Others were designed and developed by Springfield Armory personnel.

Chronoscope front view of mechanism. This is an example of the early use of electricity. The drum is covered in paper and rotates by a weight [see the rope on the drum]. An electrical current is completed at several points of the bullet's flight causing a spark to be created on the paper roll. Calculating the rotation and the distance covered on the paper where the sparks occured allows the time of flight to be calculated accurately.

SIGNAL BELL

For years the tolling of this bell alerted employees at the Water Shops that the machinery was about to be powered up. This alarm was particularly important in an era of belt-driven equipment when an unknowing worker could easily be injured if the machines suddenly began running without warning.

Lucy Stone  

Did You Know?
The request to reserve Faneuil Hall on December 16, 1873, identified the event as a celebration of the 100th anniversary of the Boston Tea Party. In truth, Suffragette Lucy Stone held the first women's suffragette meeting in the "Cradle of Liberty." She surprised many with her real agenda that day.
