For other uses, see WABCO ( disambiguation ) The Westinghouse Air Brake Company ( sometimes nicknamed or abbreviated WABCO although this was besides bewilderingly used for spinoffs ) was founded on September 28, 1869 by George Westinghouse in Pittsburgh, Pennsylvania. [ 2 ] Earlier in the year he had invented the railroad track air brake in New York state. After having manufactured equipment in Pittsburgh for a count of years, he began to construct facilities and plants east of the city where homes for his employees were built. In 1889, the tune brake manufacture facility was moved to Wilmerding, Pennsylvania, and the company ‘s general function build was built there in 1890.

In 1921 the company began manufacturing a modified air brake arrangement for initiation in trucks and heavy vehicles. [ 3 ] In 1953 WABCO entered the heavy equipment marketplace, buying the assets of leading equipment graphic designer R.G LeTourneau. [ 4 ] An entity known as LeTourneau-Westinghouse sold a roll of innovative products, including scrapers, cranes and bulldozers until 1967, when it shortened its mention to Wabco. In 1968 american english Standard purchased Wabco. WABCO ‘s directly successor companies include WABCO Vehicle Control Systems, a commercial vehicle air brake manufacturer ; and Wabtec, a railroad track equipment manufacturer, which have been owned and operated independently of each early since the mid-twentieth hundred .

history [edit ]

Westinghouse Air Brake Company [5] Westinghouse Air Brake Company ‘s Rotair Valve The Westinghouse Air Brake Company was established by George Westinghouse in 1869. In 1889, the Air Brake plant was moved to Wilmerding, Pennsylvania, a small farm township located 14 miles ( 23 kilometer ) outside of Pittsburgh. [ 6 ] At the time, was alone inhabited by about 5,000 people. socialism was strong in Wilmerding, and it was thought to be “ The Ideal Town ” for the caller because of its location immediately adjacent to the Pennsylvania Railroad and its chiefly blue-collar inhabitants. In the 1890s, the Air Brake Company employed 3,000 citizens from the surrounding Pittsburgh area, but the majority of its work force consisted of the fast ‘s employees lived in the vicinity of Wilmerding. [ 6 ] Wilmerding developed quickly around this new and growing company, and the town soon became known for this diligence. A little under one third of its population was somehow associate, and more frequently than not one would end up raising their children in the like family that they were raised in. local business prospered adenine well. [ 7 ] Many of the passengers that were departing from or coming into Wilmerding stopped to shop at these stores along the minute sidewalk before heading home. Working conditions at the Westinghouse Air Brake Company ( WA & B ) were more than adequate, and the company instituted new policies for its employees. For exemplar, in 1869, it was one of the first companies to institute a 9-hour employment day and a 55-hour work week, at a time when typical work days spanned between 10 and 12 hours ( and sometimes more ), and where a 60-hour shape week was alone considered chasten. [ 6 ] WA & B besides got the reputation for being the foremost diligence in America to adopt half holidays on Saturday afternoons. versatile benefit options were besides instituted in order to improve the work and live conditions of the firm ‘s employees. The Air Brake plant prospered, and the surrounding community thrived alongside it. By 1905, over two million freight, passenger, mail, baggage, and express cars and 89,000 locomotives were equipped with Westinghouse Air Brakes. however, clientele was seasonally variable, and there were dips a well. Wilmerding men complained that, during the non-busy temper, half routinely found themselves unemployed people. This was not surprising, given that Wilmerding was a one-industry town, and therefore unprofitable periods translated directly into a lower standard of live in the area. In the early 1900s, the Westinghouse Company built houses on a nerve pathway of land that it had purchased. In turn, it then sold those homes to its workers at an economic price. The company besides offered educational and cultural activities, normally run through the local Y.M.C.A, to obtain better workers. additionally, WA & B catered to its workers who lost their ability to work, by providing an early form of a disability indemnity plan. To insure a sealed income to employees who might have been unfit for study because of illness or injury, an coherent union would be paid to the benefactive role. Any employee under 50 was eligible for membership after a physical examen. The members contributed according to the class which they belonged to, with their class being determined by the measure of money they made per month. Their contribution ranged from fifty cents to $ 1.50, which in turn ( in casing of disability ) would pay out benefits for thirty-nine straight weeks. [ 8 ] According to Wilmerding News during this time, about 76 % of WA & B ‘s employees held a plan membership with the caller. The Westinghouse Air Brake company continued producing products in Wilmerding, with assorted managers over the years. however, with the spill of Pittsburgh ‘s industrial past, the company had become proportionately less important. [ 9 ] In 1930 Westinghouse Automotive Air Brake Company merged with Bendix Corporation to form the Bendix-Westinghouse Automotive Air Brake Company. [ 10 ]

Wabco ‘s heavy equipment roll [edit ]

between 1967 and 1983 Wabco competed, initially successfully, for marketplace share in the heavy equipment market. [ 11 ] In 1984 its wide range, including centrifugal graders, off-highway trucks, dump trucks and motor scrapers, plus its manufacture facilities, were sold to Dresser Industries. The only performing section of its construction and mine part, the Haulpak truck image, were re-branded by Dresser and continued to trade. In 1988 Dresser entered into a join-venture with Komatsu Ltd and the hand truck image continued to be manufactured .

Successors WABCO Holdings and Wabtec [edit ]

The caller has two twenty-first hundred successors, which are mugwump of each other. One, which continues to design and manufacture railway air out brakes in Wilmerding, Pennsylvania, merged with locomotive manufacturer MotivePower to form Wabtec. [ 12 ] The other, nowadays known as WABCO Holdings, designs and manufactures control systems for commercial road vehicles, including air brakes, and is headquartered in Bern, Switzerland. [ 13 ] WABCO Holdings was floated in a 2007 initial public put up by american Standard, WABCO ‘s owners for 30 years. [ 14 ] On 28 March 2019, it was announced that WABCO Holdings was to be bought by ZF Friedrichshafen for $ 7 billion US dollars, with the transaction completed in 2020. The United States Department of Justice stipulated that WABCO ‘s north american heavy-vehicle steering components business ( chiefly R.H. Sheppard Company, as acquired in 2017 ), had to be sold in holy order to preserve rival in this airfield. [ 15 ]

Development of Westinghouse Air Brake [edit ]

The straight air brake [edit ]

The beginning shape of the air brake consisted of an air pump, a independent reservoir ( pressure vessel ), and an engineer ‘s valve on the locomotive, and of a string shriek and brake cylinder on each car. One problem with this first kind of the atmosphere brake was that brake was applied to the first gear cars in a coach much sooner than to the rear cars, resulting in shocks and damages when the raise cars bunted against the cars ahead of them. The independent objection, however, was that it was not an automatic brake, i.e. even a minor bad luck like a break in match left the entire train without any brake power at all .

The homely automatic pistol publicize brake [edit ]

In 1872, George Westinghouse invented the automatic air brake by inventing the treble valve and by equipping each car with its own air cylinder. Air pressure is maintained in the accessory reservoirs and in the gearing pipe at all times when the brakes are not applied. An chemical equilibrium of tune pressure is maintained in the caravan pipe and in the aide air cylinders. To apply the brakes to all of the cars at about the same time, atmospheric pressure is released from the train pipe, causing the ternary valve on each cable car to apply the brakes. To release the brakes on each cable car, atmospheric pressure is increased in the string pipe until an surfeit atmospheric pressure above that of the atmospheric pressure in each accessory cylinder is reached, which throws the treble valve therefore as to close the intake to the bracken cylinder and open the intake to the accessory reservoir from the coach pipe, thus allowing the equilibrium of the two pressures to be reached .

The promptly military action triple valve [edit ]

Although the knit automatic air brake was a bang-up improvement over the square atmosphere brake, in an hand brake the organization hush applied the brakes to the last cars in a gearing belated than to the first cars in a train. To remedy that circumstance, George Westinghouse invented the quick action triple valve in 1887. This triple valve system was tested by George Westinghouse on the CB & Q West Burlington hill ( Iowa ) during 1887. It mechanically vents air from the brake shriek locally on each car, which applies the brakes more cursorily .

Electric railways [edit ]

For the air out brake to be employed on electric railways, an publicize compressor that is powered by electricity is required. Powerful electric locomotives were produced by the Westinghouse Electric & Manufacturing Company and by early companies .

Wheel slide protection [edit ]

In the 1930s, the company developed a rack slide security system called Decelostat that worked with its air brake.
