Inscription.  In 1941, Earl Blackburn, Vice President of J.M. Huber Corporation's Oil and Gas Division, solved a long-standing problem in Panhandle oil field production when he invented the Huber steel-bladed paraffin scraper. Before this device became a standard component of oil pumping equipment, paraffin wax dissolved in crude oil would precipitate and congeal on the inside surface of a well's tubing through which oil was pumped to the surface. When accumulation of the wax became excessive, oil stopped flowing completely. To solve this problem, thousands of feet of rods and tubing had to be pulled from the well and cleaned with steam, caustic or chemicals to remove the paraffin. Once this messy, costly cleaning process was completed, the tubing and rods were reinstalled in the well and pumping could resume.

Blackburn's prototype device was three feet long and welded to the rods. It was used with a rod rotator, another device invented by Blackburn. As the rod string went up and down, the entire string with the scrapers attached, also rotated which allowed the scrapers to shave off accumulated paraffin from the inside of the tubing. Wax shavings

were then carried to the surface in the tubing by the unobstructed flow of oil.

Blackburn tested his invention in 1941 on a Huber well which pumped for two years without paraffin trouble. Not having to pull rods and tubing regularly for cleaning greatly increased production. Word of this miracle spread around the Panhandle oil field and other oil companies rushed to buy Earl's invention, but the scrapers were not for sale. In 1946, after World War II ended, the scrapers were made available to other companies. The design of the scrapers was revised to three to four inches in length and were installed at regular intervals along each rod. Even today, Blackburn's invention is a key component to successful oil production in the Panhandle field and are still being sold.

How an Oil Well Works
A large electric motor (1) turns a v-belt (2) which rotates a gearbox (3). The gearbox greatly multiplies the power of the motor. The cranks (4) have heavy counterweights (5) attached to them. The cranks are also attached to Pitman arms (6) that are attached by the tail bearing (7) to the walking beam (8). The walking beam pivots on the saddle bearing (9). At the other end of the walking beam is the mulehead (10). The bridle (11)

is attached to the mulehead above and polish rod (12) below. The polish rod passes through the scraper rotating box (13) and connects the sucker rods (15) to the pump (16) at the bottom of the well. As the walking beam and mulehead are raised and lowered, the pump is raised and the sucker rods with the Huber scrapers attached, rotate when actuated by a cable which is attached to the beam. Each time the pump is raised (jacked), it picks up a small quantity of oil and lifts it to the surface through the tubing. As the Huber Scrapers (14) rotate, they scrape the accumulated paraffin from the inside wall of the tubing. The shavings are lifted with the oil to the surface, and pumped to tanks for storage and circulation through a heater/treater which removes salt water, gas and other impurities from the oil before it is transported to storage or a refinery.

How the Huber Scraper Works
As the sucker rods are raised and lowered by the pumpjack, the entire length of the rod string also rotates 1/4 turn on each stroke. This action scrapes the paraffin from the inside surface of the tubing, which makes the well more productive by decreasing the amount of service it needs and for increasing the amount time it can stay in service continually pumping oil.
