This interesting collection represents different specimens of road and railroad construction, from the most primitive form of early times to the highest perfection of the modern steel rail. The articles, most of which were real samples, and some of which were in part or wholly reproductions, were taken from the Museum of Permanent Way, which is one of the institutions of Osnabruck. This museum owes its foundation to the fact that the company named above has for many years been identified with the railroad interests of the world, and had the requisite enterprise and enlightenment to organize this most interesting collection. In point of time the earliest age of transit is represented by the plankroad Fig. This exhibit is an actual piece of a road laid about the fifth year of the Christian era, by Domitius. It is now covered with six feet of peat and moss. It was excavated in It is to some extent the predecessor of our modern plank roads. It will be noticed bow the planks are split out radially from the trunk. It is said that after exhumation it had to be dried in the dark to prevent it from falling to fragments.
55 types of hammers – the ultimate guide (updated for 2018)
This post is republished by request. Eliot, who took us on a tour of old artifacts around Southern Westchester, as you can see in the photos, writes: Scattered about Westchester and the Bronx are original, authentic pieces of a once glamorous and noteworthy railroad. Finding, studying and appreciating these artifacts are true exercises in suburban archaeology. I was first introduced to this railway in when my family moved from Mt.
Each railroad conducted its own experiments, so the nails used on one railroad will not be like those on other lines. For example, compare the Lehigh Valley with the New York Central: Lehigh Valley , and New York Central The LV 11 is the same style nail as the NYC square head & shank, indented numbers.
From the no-nonsense sledgehammer to the delicate mechanics hammer any balance between brute force and precision impact can be created. There is a basic formula for calculating impact force which relates to the weight of the hammerhead, length of the hammer handle, downward force and gravity. This post was originally published in October , and has been updated for freshness, accuracy and comprehensiveness.
In its most basic form you can describe your hammer as a handheld tool which is simply used to strike another object. The first hammers date back to 2, , BC when stones were used as the hammerheads then we have the first real modern day hammer with stones attached to sticks via strips of leather and animal sinew dating back to 30, BC. However, it was only really in the Bronze Age that we saw the creation of the hammers styles which we see today and often take for granted.
In reality this was the first major breakthrough in the design of the modern day hammerhead allowing for much tougher materials to be used in construction. What we see today is very often taken for granted but we do know that the range of modern day hammers can be traced back thousands of years. Design of a hammer While there are many different variations on the traditional hammer they all have two main components which are the head and the handle.
The shape, size and material used for each of these elements will vary depending upon their use. Believe it or not the force created by a hammer blow is directly proportional to the weight of the hammerhead, the length of the hammer handle, the force with which it is driven down or up and good old-fashioned gravity. We take many things for granted in the modern world but the ability to balance good old-fashioned brute force together with accuracy is not easy.

Dubuque, Iowa Railway not inclined to be a target Even federal inspectors had to chuckle as they poked about the foot-long railway in search of security threats.

Old Tool Photos mission is to provide a place for woodworkers and tool collectors to view photos of antique tools for research and reference. Searches on the Internet turned up nothing, even though this spokeshave was very common.

Deadman’s Island Shipwreck Remains of a naval railroad which served as part of ships’ cargo unloading area. There were three purposes for this project: The Deadman’s Island shipwreck served as University of Florida’s first field school in underwater archaeology. The waters around Gulf Breeze contain scores of shipwrecks from the earliest colonial days of the 17th century through World War I. The excavation of Deadman’s Shipwreck, an abandoned British sloop from the British period in Western Florida , provided valuable scientific information and served to bring the unique underwater resources into the mainstream of public attention.
In , the remains of three barrel wells on the present shore of Deadman’s Island appeared after the eroding effects of a storm. Originally the barrel wells were set some distance from the water, but the present-day shoreline is much closer inland due to erosion. UWF graduate students in the Historical Archaeology program and members of the Pensacola shipwreck survey excavated the barrel wells. Because the protruding well staves were at the water’s edge, artifact recovery was accomplished with an induction dredge.

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.
You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.

The development of railroads was one of the most important phenomena of the Industrial Revolution. With their formation, construction and operation, they brought profound social, economic and political change to a country only 50 years old. Over the next 50 years, America would come to see magnificent bridges and other structures on which trains would run, awesome depots, ruthless rail magnates and the majesty of rail locomotives crossing the country.
The railroad was first developed in Great Britain. A man named George Stephenson successfully applied the steam technology of the day and created the world’s first successful locomotive. Even rails were largely imported from England until the Civil War. This stereograph of the Central Pacific Railroad would have appeared three-dimensional when viewed through special glasses.
Baltimore, the third largest city in the nation in , had not invested in a canal. Yet, Baltimore was miles closer to the frontier than New York and soon recognized that the development of a railway could make the city more competitive with New York and the Erie Canal in transporting people and goods to the West. There were great parades on the day the construction started. On July 4, , the first spadeful of earth was turned over by the last surviving signer of the Declaration of Independence, year-old Charles Carroll.
New railroads came swiftly. Although the first railroads were successful, attempts to finance new ones originally failed as opposition was mounted by turnpike operators, canal companies, stagecoach companies and those who drove wagons.
