What is claimed is:
1. 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.
