  • MRM & VPS Shock Isolation Systems for Forging Hammers
    VVIBROIBRO/DDYNAMICYNAMICS ® vibration and shock isolation systems MMRMRM™ & VPSVPS™ ShockShock IIsolationsolation SystemsSystems forfor FForgingorging HammersHammers Forging Hammer Isolation Vibro/Dynamics began producing isolation systems for forging hammers in 2002 after receiving numerous requests for an improved mounting system from hammer builders and forging producers. Vibration and shock isolation of forging hammers is very difficult due to their large masses and extreme shock forces. Vibro/Dynamics first developed the FS Series Coil Spring Isolators with viscous fluid dampers and then followed with the development of MRM™ and VPS™ Elastomeric Isolation System. Both types have proven to be very effective in isolating hammer and shock forces. Coil spring and viscous damper units provide the greatest isolation performance, but have higher initial cost, more expensive foundations, and potential maintenance issues. The viscous dampers in the spring isolators are difficult to protect if a pit should flood; a situation usually requiring the replacement of the damper fluid. Some competitive damper designs have leaked due to the cracks developing in the damper tube walls, which requires the removal and repair of the spring isolators. As a result, the MRM and VPS Systems has become an accepted standard for FSV20 and FSX20 Viscous Damped Spring Mounts vibration and shock isolation around the world. They offer superior isolation performance over timber and pad systems without the larger inertia mass, flooding issues, and higher maintenance cost associated with coil spring isolator systems. They are easy to install and maintain and have proven to be durable. This document seeks to address the technical issues involved in the isolation of forging hammers.

  • THE STEAM BOILER, by Joseph HARRISON~Jr., Philadelphia
    THE STEAM BOILER. 89 THE STEAM BOILER, By JosEPH HARRISON~Jr., Philadelphia. 0]~ all the elements that have been pressed into man's service, to increase his comforts and conveniences, water turned into steam holds a most important place. And strange as it may appear to the unin- formed, it might almost be said, that the steam-engine as matured by James Watt, came from his hands nearly perfect in principle, and, like Minerva from the brain of Jupiter, fully armed and ready to do battle in the varied fields in which it has since been employed. James Watt knew all, and actedwlth a knowledge of all, or nearly all, the principles that are now known. The main improvements in the steam- engine of our time, consist-in a better and simpler arrangement and proportions of parts, better material, better workmanship, and vastly increased size. Many of its better qualities are the result of improved means of manufacture in the use of the steam-hammer,--the planlng machine, slotting machine, etc., etc., which with equally improved quality of material, has enabled the steam-engine builder to do such work, as could not have been done under a less improved system, and for which Watt might have sighed in vain. Not so the steam-boiler. It, from the very ~irst application of steam as a ttseful agent, has been the constant trouble of the engine-builder, and the engine user, the great source of anxiety, danger and expense. The first patent regularly issued in England for a steam-boiler, dates about a century back, and from that time to this, patents for new de- signs or improvements, numbering thousands, have been issued in Eng- land,--on the continent of Europe, and in this country.

  • CHARLESTOWN NAVY YARD, CHAIN FORGE (Smithery) (Building 105)
    HISTORIC AMERICAN ENGINEERING RECORD CHARLESTOWN NAVY YARD, CHAIN FORGE (Smithery) (Building 105) HAER No. MA-90-3 Location: Charlestown Navy Yard, Boston, Suffolk County, Massachusetts Building 105 is located at latitude: 42.376258 and longitude: -71.052419. The coordinate represents the structure’s southwest corner. This coordinate was obtained on August 1, 2013, using Google Earth imagery dated April 9, 2013. Building 105 has no restriction on its release to the public. Present Owner: Boston Redevelopment Authority (BRA) owns Building 105, but the National Park Service owns the machines still in the building. Present Use: Not in use. Significance: The Charlestown Navy Yard’s Chain Forge is significant for its role as the leading manufacturer of anchor chain and anchors for the U.S. Navy in the twentieth century, as well as for the innovations in chain design and manufacture developed by its employees. In particular, the invention of Die-Lock chain by yard employees Albert M. Leahy, Carlton G. Lutts, and James Reid resulted in the designation of Die-Lock chain as the U.S. Navy’s standard and the Charlestown Navy Yard as the U.S. Navy’s supplier. Although production ceased in the 1970s with the closure of the navy yard, the forge retains a nearly complete inventory of the forges, hammers, presses, and other machinery necessary for production. In addition, there are a number of unique extant machines, such as the 1917 Tinius Olsen chain testing machine, one of only two built, and the nearly complete assembly plant for 4-3/4" Die-Lock chain. Historian: Justine Christianson, HAER Historian, 2013-2014 Project Information: The Historic American Engineering Record (HAER) is a long- range program that documents and interprets historically significant engineering sites and structures throughout the United States.

The metal is subjected to stress.It is a process of changing the shape and size of the material under the influence of external force or stress.Plastic Deformation occurs. Classification of Metal Working Processes 1. General classification i. Rolling ii. Forging iii. Extrusion iv. Wire Drawing v. Sheet Metal Forming 2. Based on Temperature of Working i. Hot Working ii. Cold Working iii. Warm Working 3. Based on the applied stress i. Direct Compressive Stress ii. Indirect Compressive Stress iii. Tensile Stress iv. Bending Stress v. Shear Stress Classification of Metal Working based on temperature. Hot working: It is defined as the mechanical working of metal at an elevated (higher) temperature above a particular temperature. This temperature is referred to RCT(Re Crystallization Temperature). Cold Working: It is defined as the mechanical working of metal below RCT. Warm Working: It is defined as the mechanical working of metal at a temperature between that of Hot working and Cold Working. Ingot is the starting raw metal for all metal working process. Molten metal from the furnace is taken and poured into metallic moulds and allowed to cool or solidify. The cooled solid metal mass is then taken out of the mould. This solid metal is referred to as Ingot.This Ingot is later on converted to other forms by mechanical working.

The international intrigue, the testimonies citing immaculate conception, and the accusations of piracy that have contested the birth of this singular technology will not be laid to rest with the dedication of this landmark. The towering Creusot hammer may be considered symbolic not only of the achieve- ments of the Creusot ironworks, but of the multi-national origins of the concept of the steam hammer, with credit spread among such French engineers as François Cavé, Eugène Schneider, and François Bourdon, and British engineers James Nasmyth, William Deverell, and James Watt.
