In a device of the character described, a bow having a string attached thereto, a pair of silencers fric tionally mounted on said string and said silencers being arranged in spaced apart relation with respect to each other, each of said silencers comprising a body member made of yieldable material and having a one piece for mation, each body member being provided with a cen tral hub having an aperture therein for the projection therethrough of the string, the outer surfaces of the 10 hub being tapered, a plurality of equally spaced radially disposed arms arranged approximately one hundred and wenty degrees apart on said hub, and ribs on the outer surfaces of said arms extending parallel to the longi tudinal axes of the arms, said silencers serving to dampen out how string “twang” by deadening vibration nodes at points where they peak in the string when the bow is shot so that game will be prevented from ?inching or “ducking” the arrow due to the loud “twang” of the bow string, and wherein game will be prevented from 2 locating the hunter from the sound of the string. 2. In a device of the character described, a bow hav ing a string connected thereto, and a pair of spaced apart silencers mounted on said string for deadening 4 vibration nodes at points where they peak in the string when the bow is shot, each of said silencers being made of yieldable material and each being shaped to include an apertured central hub provided with a plurality of radially disposed spaced apart arms, said arms being integral with said hub. 3. As a new article of manufacture, a bow string silencer fabricated of a single piece of resilient material and shaped to include a body member, said body member being provided with a central hub which has an aperture therein for the projection therethrough of a string, the outer surfaces of the hub being tapered, a plurality of equally spaced radially disposed arms arranged approxi mately one hundred and twenty degrees apart on said hub, and ribs on the outer surfaces of said arms extend ing parallel to the longitudinal axes of the arms.
