In modern archery, a compound bow is a bow that uses a levering system, usually of cables and pulleys, to bend the limbs. [1] The compound bow was first developed in 1966 by Holless Wilbur Allen in North Kansas City, Missouri , and a US patent was granted in 1969.
The binary cam is a design for the pulley system of a compound bow. Craig Yehle, director of research and development at Bowtech Archery, received a patent [1] for the design on December 11, 2007. Bowtech started equipping its bows with the new cam design in the 2005 model year. [2] [3]
The compound bow, not to be confused with a composite bow, is a modern bow that uses a levering system, usually of cables and pulleys, to bend the limbs. The limbs of a compound bow are much stiffer than those of a recurve bow or longbow. This limb stiffness makes the compound bow more energy-efficient than other bows, in conjunction with the ...
A = bow riser/grip, B = median plane of the bow, C = arrow aiming line and trajectory Arrow flexing both towards and away from the bow handle. The archer's paradox is the phenomenon of an arrow traveling in the direction it is pointed at full draw , when it seems that the arrow would have to pass through the starting position it was in before ...
In the 1960s, he sawed the ends off a conventional recurve bow and then added pulleys to each end. [1] Allen experimented with a number of designs to apply for a patent on June 23, 1966, [2] and U.S. patent 3,486,495 was granted to him in December 1969. With the help of bowmaker Tom Jennings, he became the first manufacturer of compound bows ...
Winter brings less daylight and colder temperatures, which can disrupt sleep. Seasonal Affective Disorder (SAD) is more common in winter due to the lack of sunlight, causing sleep disturbances.
Modern compound bows usually also have a peep sight (rear sight) built into the string, which aids in a consistent anchor point, but this is not allowed for other bow types under World Archery. Modern compound [65] bows automatically limit the draw length to give a consistent arrow velocity, while traditional bows allow great variation in draw ...
