J&H McLaren was a British engineering company in Hunslet, Leeds, England, that manufactured traction engines, stationary engines and later, diesel engines.

The company was founded in 1876 by John and Henry McLaren. They had both been apprenticed to Black, Hawthorn & Co of Gateshead, builders of railway locomotive and marine engines. The new Midland Engine Works was situated on Jack Lane in Hunslet, Leeds within sight of many of the great engineering companies of Leeds, e.g. Hudswell Clarke, Hunslet Engine Co. Manning Wardle, John Fowler & Co. and Kitson & Co.

Steam power

McLaren's first traction engine was built in 1877.^[1] The company rapidly developed a range of traction engines, steam rollers, ploughing engines, agricultural implements and stationary engines. One of their forgotten achievements is the invention, British Patent 763 of 1880, of the traction-centre engine, for driving steam-powered fairground roundabouts.^{[ citation needed ]} This is often wrongly attributed to Savage of King's Lynn.^{[lower-alpha 1]} In the 1890s, McLaren developed a range of vertical triple-expansion engines for the new industry of electricity generation. The zenith of this effort was a pair of 3000 ihp engines for Leeds Corporation’s Whitehall Road Power Station. After the start of the 20th century, the company introduced a tractor for direct haulage and a range of powerful direct-ploughing engines. The largest of these, rated 125 ihp, was fitted with superheater, feedwater heater and fully lagged cylinders. This provided a very efficient engine, which won many awards both at home and abroad. Other products were, showmen's engines, crane engines, portable engines, railway locomotives and Darby Steam-Diggers.

McLaren had a good overseas market with over 50% of goods exported. They had local offices in New Zealand, Australia, South Africa, and South America with smaller representation in Hungary, Germany and Italy. In 1886 they sold three traction engines to the French postal service.^[3] The last of the traction engines was exported to South Africa in 1938 and is preserved in Johannesburg.

Diesel power

During the First World War, McLaren inevitably became involved in the war effort. The works were particularly noted for producing a collet chuck for holding shells during turning. For his efforts during the war, John McLaren was knighted, but unfortunately his reward was short-lived, for he died in 1920.

After the First World War, McLaren built a cable-ploughing windlass, initially powered by a Dorman petrol engine but a diesel engine was sought. In 1926 the company entered into an agreement with the German Company Benz to manufacture diesel engines. These were the first automotive-type diesel engines produced in volume in Britain, and as a result were in the forefront of the use of diesel engines for road, rail, and agricultural purposes. Examples include the first diesel-powered railway locomotive, built by Hudswell Clarke in Leeds and powered by a McLaren-built diesel. The first diesel-powered commercial vehicles in Britain were made by Richard Garrett & Sons of Leiston in 1928, and Kerr Stuart of Stoke-on-Trent, again powered by McLaren-built diesels. In addition, McLaren built Britain's first diesel-powered road roller in 1927 using their own engine. A complete range of diesel engines was designed up to around 400 hp and these were very widely used for industrial applications. One particularly successful use was in standby power sets.

In 1943, the business was sold by the family to the Associated British Oil Engine Company and this was initially very successful. A major contract with the USSR for diesel-generator sets resulted in the number of employees increasing tenfold and new buildings acquired. In December 1945, McLaren took over the remains of Kitson & Co. and with it their Airedale Works. McLaren had an arrangement with Petters Limited and some engines were sold under the name Petter-McLaren.^[4]

Closure

In 1957, the take over of the Brush A.B.O.E. Group by Hawker Siddeley saw the Leeds production facility fade away and the main works closed in January 1959.

About 40 of McLaren’s steam engines survived into preservation.^[1]

Under the Whyte notation for the classification of steam locomotives, 0-4-0 represents one of the simplest possible types, that with two axles and four coupled wheels, all of which are driven. The wheels on the earliest four-coupled locomotives were connected by a single gear wheel, but from 1825 the wheels were usually connected with coupling rods to form a single driven set.

A traction engine is a steam-powered tractor used to move heavy loads on roads, plough ground or to provide power at a chosen location. The name derives from the Latin tractus, meaning 'drawn', since the prime function of any traction engine is to draw a load behind it. They are sometimes called road locomotives to distinguish them from railway locomotives – that is, steam engines that run on rails.

John Fowler & Co Engineers of Leathley Road, Hunslet, Leeds, West Yorkshire, England produced traction engines and ploughing implements and equipment, as well as railway equipment.

Under the Whyte notation for the classification of steam locomotives, 0-6-0+0-6-0 represents the wheel arrangement of an articulated locomotive with two separate swivelling engine units, each unit with no leading wheels, six powered and coupled driving wheels on three axles and no trailing wheels. The arrangement is effectively two 0-6-0 locomotives operating back-to-back and was used on Garratt, Double Fairlie, Meyer and Kitson-Meyer articulated locomotives. A similar arrangement exists for Mallet steam locomotives on which only the front engine unit swivels, but these are referred to as 0-6-6-0.

James & Fred Howard of Britannia Ironworks, Bedford, later known simply as Howards, were one of the largest English makers of agricultural equipment, steam traction engines, and light railway equipment. At The Great Exhibition of 1851 they exhibited a range of horse-drawn implements. After World War I, Howards became part of AGE, Agricultural & General Engineers, along with many of the other British makers of similar machinery.

An industrial steam locomotive is a type of steam locomotive which primarily ran on industrial railways to serve a company by transporting or assisting the manufacturing products of that particular company's produce. Industrial railways often transported items such as coal, iron, slate and workers to aid production. In many countries, industrial steam serving coal mines in particular, lasted significantly longer than the nations otherwise mainline steam traction, due to the readily available fuel.
