The origin of the screw and the screwdriver is lost to the pages of history, though some believe the first screw-like tool originated around the first century. They were probably invented in the late 15th century, either in Germany or France. 3.2. Phillips-head screws have a deeper, more positively engaging slot. Robertson, a native Canadian. Self-Centring Design A Phillips screw offers many of the benefits of a Robertson and can be driven by a traditional slotted screwdriver in a pinch. The tool's original names in German and French were Schraubendreher (screwturner) and tournevis (turnscrew), respectively. A Phillips is, arguably, not a better screw than a Robertson. By 1940, 85% of U.S. screw manufacturers had a license for the design. However, too much torque and the screwdriver will slip. Phillips is a trademark used for a screw with a head having two intersecting perpendicular slots and for a screwdriver with a tip shaped to fit into these slots. Robertson designed a fastener that featured a square socket tapering towards a truncated pyramidal bottom, winning a Canadian patent for his work in 1907. Supposedly, Phillips screwdrivers were designed that way. He later sold it to Henry F. Phillips who formed the Philips Screw Company, giving the screw drive the name it is known by to this day. The screwdriver presented a solution to the frequent problem users encountered with flathead screwdrivers: the driver often slipped out of place and slowed down the process of securing the fasteners. Henry F. Phillips, of Portland, OR, invented the X-shaped socket head screw for car makers who needed a screw that could be driven with more torque and that would hold more tightly than slotted screws. [5] One of the first customers was General Motors who used the innovative design in 1936 for its Cadillac assembly-lines. Phillips drives, on the other hand, require a significantly reduced number of permutations. The screwdriver uses applied torque to tighten down screws and bolts. [2] Phillips' major contribution was in driving the crosshead concept forward to the point where it was adopted by screwmakers and automobile companies. Screws with a Phillips drive can be tightened and loosened using a Phillips screwdriver. Patents #2,046,837 to 2,046,840) for the American Screw Company of Providence, Rhode Island, Phillips succeeded in bringing the design to industrial manufacturing and promoting its rapid adoption as a machine screw standard. That’s because Henry Ford wanted to use Robertsons in all of his plants, and he wanted more control over how they were made. Henry Phillips invented and patented the Phillips ® design in 1936. According to the American Society of Mechanical Engineers, toolmaker Joseph Whitworth devised Britain’s first standardized screw in 1841. The official history from the Robertson Screw Company says that Robertson, a Canadian inventor and industrialist, cut himself when the blade slipped during a demonstration of a new spring-loaded screwdriver, forcing an epiphany that the world needed a new type of screw. Standardized screw heads and screwdrivers emerged later. The flat head or slotted screwdriver was the first known head for a screwdriver. The Phillips head screw was compatible with the automated screwdrivers used in assembly line.

In its modern form, the flat-head screwdriver was probably invented in about 1744 in England, where it was known as a "turn-screw"—a type of bit used as an attachment in a carpenter's brace-and-bit tool. Locating the screwdriver in the screw is easier, and more torque (twisting force) can be applied. [1], The importance of the crosshead screw design lies in its self-centering property, useful on automated production lines that use powered screwdrivers.

Phillips licensed his design to the giant American Screw Company, which got General Motors to use the screw in the 1936 Cadillac. Phillips screwdriver. Consumer Reports once wrote that “compared with slotted and Phillips-head screwdrivers, the Robertson worked faster, with less cam-out.” However, cam-out was good for automakers increasingly relying on automation, as it meant screws wouldn’t be overtightened. Phillips screwdrivers can be used for Pozidriv screws, but they do exhibit some play. This … Henry Frank Phillips (June 4, 1889 – April 13, 1958) was an American businessman from Portland, Oregon. The Robertson screw is better in multiple ways, but Henry Ford sealed its fate in the U.S. Pozidriv screwdrivers, on the other hand, cannot be used for Phillips screws. Phillips licensed his design to the giant American Screw Company, which got General Motors to use the screw in the 1936 Cadillac. Meanwhile, other engineers worked on their own types of screw heads. Phillips Head Screw In the early 1930s, the Phillips head screw was invented by Henry Phillips. But the truth is that the screwdriver is really named after Henry F. Phillips, the owner of the company which purchased the design from its inventor John P. Thompson. American engineer William Sellers did the same for his country in 1864. So old is this tool that the first historical mention dates back to the 1500s. [4] Phillips formed the Phillips Screw Company in 1934. In One Good Turn: A Natural History of the Screwdriver and the Screw, Witold Rybczynski, professor of urbanism at the University of Pennsylvania, traces the metal fasteners to the 15th century, though it wasn’t until the early 18th century that the screw became common. But unless you’re Canadian, there’s a good chance you’ve never heard of Robertson screws. His inventions built on an earlier concept credited to the inventor J. P. Thompson.

WORLD'S BEST TREE FELLING TUTORIAL! By contrast, a slotted drive would require 'six or more' sizes of screwdriver for the same size range. Its history explained in chapter 2.2. [6] Due to failing health, Phillips retired in 1945. The screwdriver is made up of a head or tip, which is Within the decade, almost all automakers were using Phillips screws. The Phillips-head screwdriver was invented to overcome the issues with slotted screws.

Phillips (1890 – 1958) was a U.S. businessman from Portland, Oregon, and inventor of the Phillips-head screw and screwdriver. Early screws used either a slotted head or some sort of square or octagonal drive. The Phillips head screw was compatible with the automated screwdrivers used in an assembly line. Way more information than … The inventor of the Phillips screw was Henry F. Phillips, a businessman from Portland, Oregon, who obviously had a lot of time on his hands. Henry Phillips of the Phillips Screw Company in Portland, Ore., invented a screw that would take more torque than the usual screw with its single slot, on which the screwdriver would be easily centered and would be less likely to slip.
