Straker-Squire
Straker-Squire (also known as Brazil Straker) was a British automobile manufacturer based in Bristol, and later Edmonton, London, Edmonton in North London. The company was formed in 1893 at St Philips Marsh, Bristol, St Philips, Bristol, as Brazil, Straker & Co by the Irish engineer J.P. Brazil and the London motor agent Sidney Straker. In 1899 Sidney Straker joined forces with Edward Bayley and went into production of steam wagons, joining in partnership with L.R.L. Squire in 1904 and production reached 200 steam wagons by 1906. In 1907 the company moved into a new factory on Lodge Causeway, Fishponds, at first to manufacture commercial vehicles, including large numbers of early London Buses, and a French car design under licence. The company also produced and successfully raced a number of its own car designs. When World War I started, Sir Roy Fedden, their chief designer, convinced the company to take on aircraft engine repair and manufacture, and that arm of the company wa ...

Roy Fedden
Sir Alfred Hubert Roy Fedden MBE, FRAeS (6 June 1885 – 21 November 1973) was an engineer who designed most of Bristol Engine Company's successful piston aircraft engine designs. Early life Fedden was born in the Bristol area to fairly wealthy and influential parents. His older brother was the artist Romilly Fedden. Fedden's family was the first in the area to own a car, an interesting parallel with fellow engine designer, Harry Ricardo. This early influence almost certainly led to his future career. Fedden attended Clifton College, but did not do well scholastically and was known primarily for sports. After leaving, he declined to enter the Army, and announced he would apprentice as an engineer. Apprenticeship His apprenticeship was completed in 1906, and he immediately designed a complete car. He managed to convince the local firm of Brazil Straker to hire him, and the design was produced as the successful Shamrock. He remained at Brazil Straker over the following years ...

Cosmos Engineering
Cosmos Engineering was a company that manufactured aero-engines in a factory in Fishponds, Bristol during World War I. Sir Roy Fedden, the company's principal designer, developed the 14-cylinder radial Mercury engine during this period. The company was taken over by the Bristol Aeroplane Company in 1920. Company origins In 1918 the Anglo-American company Cosmos bought Straker-Squire (also known as Brazil Straker), a car and bus manufacturing firm which had branched out into aircraft engine repair and manufacture. This began by first reconditioning, then substantially redesigning and re-manufacturing Curtiss OX-5 engines. Due to the quality of this work, they were the only company permitted to manufacture Rolls-Royce aircraft engines under licence, building Hawk and Falcon engines, major components for the Eagle engine and also 600 Renault 80hp 8Ca engines. Over 1,500 engines were produced in total. The company was one of the first to be brought under Admiralty control, and Fe ...

Overtype Steam Wagon
A steam wagon (or steam lorry, steam waggon or steamtruck) is a steam-powered truck for carrying freight. It was the earliest form of lorry (truck) and came in two basic forms: ''overtype'' and ''undertype'', the distinction being the position of the engine relative to the boiler. Manufacturers tended to concentrate on one form or the other. Steam wagons were a widespread form of powered road traction for commercial haulage in the early part of the twentieth century, although they were a largely British phenomenon, with few manufacturers outside Great Britain. Competition from internal-combustion-powered vehicles and adverse legislation meant that few remained in commercial use beyond the Second World War. Although the majority of steam wagons have been scrapped, a significant number have been preserved in working order and may be seen in operation at steam fairs, particularly in the UK.

Sentinel Boiler
The Sentinel boiler was a design of vertical boiler, fitted to the numerous steam wagons built by the Sentinel Waggon Works. The boiler was carefully designed for use in a steam wagon: it was compact, easy to handle whilst driving, and its maintenance features recognised the problems of poor boiler feedwater, feedwater quality and the need for it to be maintained by a small operator, rather than a major locomotive works. Although this design was used in most of Sentinel's products, they also produced larger boilers of quite different types for their :Sentinel locomotives, railway locomotives. Description Sentinel boilers are vertical, as was common for many designs of steam wagon, so as to reduce the effects of tilting due to hill climbing or uneven roads disturbing the Glossary of boiler terms#Water_level, water level. It also provides a compact boiler that leaves adequate space in the cab for the crew, controls and coal bunker, whilst leaving as much as possible of the wa ...

Fishponds
Fishponds is a suburb in the north-east of the English city of Bristol, about from Bristol city centre, the city centre. It is mainly residential, and housing is typically terraced Victorian. It has a small student population from the presence of the Glenside, Bristol, Glenside campus of the University of the West of England. Fishponds is home to Oldbury Court, a Victorian landscaped park. The River Frome, Bristol, River Frome runs through the area with the Frome Valley Walkway alongside it. A restored mill found at Snuff Mills has kept its original waterwheel, which can still be seen and heard turning. To the south-west of the neighbourhood is Eastville Park. The name Fishponds derives from former quarries which upon abandonment became large fishponds. Most of these have since been filled in. One remains and was a popular swimming area nicknamed "The Lido (swimming pool), Lido" until the mid-1970s, when it was acquired by an angling club. Transport Fishponds is mainly serve ...

Compound Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure (HP) cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure (LP) cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a steam c ...

Water-tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum via large-bore 'downcomer tubes', where it pre-heats the feedwater supply. (In large utility boilers ...
