Lawn Sprinkler Background The lawn sprinkler is a mechanism through which water is distributed in a spray so that a residential lawn or garden is irrigated. Sprinklers may take extraordinarily large forms, such as the irrigation systems used by professional farmers to water crops in the field. Many serious gardeners employ landscaping firms to develop and install expensive, permanent sprinkler systems in the ground. However, the average American simply purchases an inexpensive plastic and metal sprinkler and attaches it to a garden hose so that the sprinkler disseminates the water evenly. Residential use lawn sprinklers take a wide variety of forms and are available in a wide variety of materials and associated prices. However, the oscillating sprinkler, with a metal arm that sprays out a fan-shaped curtain of water in an area approximately 600 ft2 (55.7 m2), is likely the most popular. Such oscillating sprinklers sell for well under $10, but can be over $40. The permanency of the materials generally determines the price.

The less expensive, plastic and aluminum oscillating sprinkler is very simple in construction and in operation. Most include only a base that enables the piece to seat securely on the lawn, an oscillating arm, a bracket with regulating cam (it controls the width of the fan spray as it moves the spray arm), the mechanical motor, and the connectors to the garden hose. The oscillating sprinkler works on the principle that water provides the power to move the elliptical cam (or heart-shaped cam in some models) which moves the sprinkler arm. Water spins a simple turbine which must be attached to a series of gears stacked up (called a gear train) to slow down the speed of the water.

Without the insertion of the gear train the cam and the oscillating arm would move much too quickly. The gear train reduces the speed of the incoming water so that the cam moves at only about one mile per hour.

History The advent of the residential lawn sprinkler is inextricably bound with Americans' desire to cultivate the yard for fun and aesthetic reasons and not for farming purposes. In fact, Americans of the seventeenth and eighteenth centuries did not think much of developing bucolic spaces in and around their homes. The town square in New England, now gorgeous green pastures, was a scruffy piece of land in which cattle could graze. In the nineteenth century attitudes toward the cultivation of the lawn change for two reasons. First, more Americans moved out of the city to the evolving suburbs as rail transportation enabled them to live further from places of business. As they moved out where there was space for gardens there was the urge to work the lawn as a hobby. Beautifying the home and garden were thought to strengthen the family. Secondly, Victorian Americans began to long for the rural New England they thought they were losing while others wanted to emulate the pastoral estates developing in England. Notable landscape architects urged Americans to beautify their property and published treatises and designs to help them achieve this goal.

Lawn sprinklers require a city water delivery system because they are generally used with a hose. Such systems were not in place in large measure until about 1870. The very wealthy used fountains to water the lawn and dazzle neighbors. Patents on lawn sprinklers follow in short order; the first patent on an American lawn sprinkler was issued in 1871. Hose reels, nozzles, and sprinklers were advertised by 1900. Sprinklers took various forms. Large contraptions that rolled on carts with immense yardage of rubber hose were popular with some in the early twentieth century. By about 1930 the mechanisms took other forms such as cast metal with a three or four-arm rotating head that shot water as it spun around. Some were formed in the shape of animals with a rotating arm on the top. Plastic-bodied sprinklers followed in the later 20th century.
