Although Vulcan never placed it into production, the Single-Compound hammer was one of Vulcan's more interesting experimental hammers, and under different market circumstances has the potential of success. Although a general long-term success, Vulcan always recognised that the product life of the air/steam hammer line wasn't infinite, especially offshore. Given the difficulties of developing an … Continue reading Single-Compound Hammer
For the first three decades of the twentieth century, Vulcan issued a "general" product bulletin which featured all of its products in product. (Some material from those bulletins is here.) In a pre-internet age, printed bulletins were about the only way a company could advertise its products and provide its customers (current and prospective) information … Continue reading Vulcan Product Bulletins
Virtually all vibratory pile drivers use rotating weights to produce the alternating force that mobilises and fluidises the soil. But it's necessary to use the weights in pairs to cancel out the horizontal forces that result. What if the force could be produced using a reciprocating weight, thus eliminating the horizontal cancellation requirement? In the … Continue reading Reciprocating Vibratory and Impact-Vibration Hammers
As the Nilens concern inched (or more accurately millimetred) its way to receivership, Vulcan embarked upon a project using one of their hammers that, had it succeeded, would have made an interesting addition to Vulcan's lineup: the Liquid Propane Gas (LPG) hammer. As was the case with noise pollution, the 1970's were also the years … Continue reading Liquid Propane Gas (LPG) Hammer

We looked at the hammers that began the change in Vulcan's product direction during the late 1920's and early 1930's, and we also document the "last hammers" of the 1990's. Here we look at hammers which were proposed during the 1960's, 1970's and 1980's that were never built. One other set of designs that never … Continue reading Proposed Hammers During the 1960’s, 1970’s and 1980’s
As we noted elsewhere, Vulcan was an innovator from the beginning of the air/steam line in the 1880's until the end of the Illinois corporation and beyond. Unfortunately, from the mid-1990's on, Vulcan was unable to take its ideas and put them into reality. An example of this is the Sea Water Hammer. But there … Continue reading Vulcan’s “Last Hammers”
Very few companies can claim even a century-long existence. Not counting the Cari years, Vulcan Iron Works endured for 144 years from its founding by Henry Warrington until 1996. The portion of vulcanhammer.info focuses on the first hundred years "and then some:" the years the company was located in Chicago, 1852-1960. During this time, the … Continue reading Vulcan Iron Works: The First Century
George was the only one of the three Warrington brothers to marry; Chester was his only child. In 1933, with James Warrington's death, Chester inherited a company with which he had had little to do until that time. He attempted to direct it from Washington. The failure of Cord-Auburn-Duesenberg, coupled with a looming war and … Continue reading Vulcan At War
