History of the Fresno Scraper
Digging irrigation ditches to thirsty fields with the Fresno Scraper
J. Porteous' Dirt Scraper
A letter written by Ivan L. Pfalser of Caney, Kan., appeared in the October 2001 issue of Farm Collector magazine, inquiring about how the Fresno scraper got its name. Here's some history on that scraper:
The city of Fresno lies about 200 miles north of Los Angeles in California's lush San Joaquin Valley. Pioneers in Fresno County during the 1870s realized they needed to irrigate in order to unlock the great fertility of the land. There was plenty of water in the San Joaquin River, but many ditches were needed to divert that water to the thirsty fields.
To dig the ditches, the pioneers first used a crude and inefficient wooden tool known as a buck scraper, which was pulled by mules.
By the early 1880s, a Fresno wagon shop owner named James Porteous improved on the original buck scraper design. Born in 1848 in Haddington, Scotland, Porteous was the son of a wheelwright and blacksmith. In 1873, he immigrated to the United States, moving to Fresno and establishing his shop. Originally named the Fresno Agricultural Works, it is now known as the Fresno Ag Hardware. It became the largest agricultural implement business in the valley and today is the oldest continuously operated business in Fresno.
Porteous, credited with more than 2,000 patents, received Patent No. 261,759 for his 'Dirt Scraper' on July 25, 1882. The device had a front board that measured 8 feet wide by 2 feet high, with a steel cutting edge along the bottom and short end boards. There was a tailboard upon which the operator stood, which forced the cutting edge into the ground.
To haul the dirt, the front board was folded back flat by means of a lever, and the load was held in place by the end boards, although it looks as though a lot of the load would have fallen off.
A couple of years later, another Fresno blacksmith, Abijah McCall, invented a scoop-style, rollover scraper made of iron. McCall had experience as an earthmover on the irrigation ditches and, according to J.L. Allhands in his book Tools of the Earthmover, McCall's scraper 'proved to be the earth-movingest mule-powered tool ever devised.'
Frank Dusy reportedly loaned McCall the $150 needed to get a patent in return for half interest in the invention, and Patent No. 320,055 was issued to them on June 16, 1885.
The Dusy-McCall scraper had a metal bottom, sides and rear, with rounded rollover shoes at each end in the front. A tipping handle was attached at the rear and to two small wheels on a drawbar at the front. In use, the operator raised the handle enough to cause the front cutting edge to bite into the soil. After the scoop was filled, down pressure on the handle raised the cutting edge clear of the ground, which allowed the loaded scoop to be pulled to where it was dumped.
To unload, the handle was raised, the edge caught and the scoop rolled over on the rounded shoes, dumping the dirt. As the scoop was dragged over the load, it leveled the dirt to some extent. Originally made 8 feet wide, it was reduced to 6 feet when the larger size proved too much for six mules to handle.
