In 1920, the Hurley Machine Company introduced the Thor vacuum cleaner, believed to be the first electric vacuum cleaner manufactured in the United States. [4] Sometime during the 1920s, the Hurley Machine Company became a subsidiary of the newly formed Electric Household Utilities Corporation, still under the control of the Hurley brothers.
A corded hammer drill next to a drill bit and a chuck key. A hammer drill, also known as a percussion drill or impact drill, is a power tool used chiefly for drilling in hard materials. [1] [2] It is a type of rotary drill with an impact mechanism that generates a hammering motion.
Portable power tools have obvious advantages in mobility. Stationary power tools, however, often have advantages in speed and precision. A typical table saw, for instance, not only cuts faster than a regular hand saw, but the cuts are smoother, straighter, and more square than what is normally achievable with a hand-held power saw.
Modern units allow the hammer and rotation functions to be used separately or in combination, i.e., hammer mode, drill mode, or both. When used in the hammer mode, the tool provides a drilling function similar to a jackhammer. [4] Rotary hammer drills have an oil filled gearbox, which allows them to operate durably despite the large forces and ...
Pneumatic drills were developed in response to the needs of the mining, quarrying, excavating, and tunneling. A pneumatic drill was proposed by C. Brunton in 1844. [4] [5] In 1846, a percussion drill that could be worked by steam, or atmospheric pressure obtained from a vacuum, was patented in Britain by Thomas Clarke, Mark Freeman, and John ...
Pneumatic tools are rated using several metrics: Free Speed (rpm), Air Pressure (psi/bar), Air Consumption (cfm/scfm or m3/min), Horse Power (hp), and spindle size. Each individual tool has its own specific requirements which determine their compatibility with air compressor systems.
Cleveland's P.A. Geier Company had obtained a patent on a cyclonic vacuum cleaner as early as 1928, which was later sold to Health-Mor in 1939, introducing the Filter Queen cyclonic canister vacuum cleaner. [31] In 1979, James Dyson introduced a portable unit with cyclonic separation, adapting this design from industrial saw mills. [32]
Peck drilling involves plunging the drill part way through the workpiece, no more than five times the diameter of the drill, and then retracting it to the surface. This is repeated until the hole is finished. A modified form of this process, called high speed peck drilling or chip breaking, only retracts the drill slightly. This process is ...
