ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
The present invention relates to archery bows and more, particularly, to novel, improved devices for minimizing the sound generated by a bow string when an arrow is released.
BACKGROUND OF THE INVENTION
A bow string makes a relatively loud sound when an arrow is released. This is disadvantageous as the sound may be loud enough to frighten away game a hunter is seeking or cause the bowman to flinch and the arrow to consequently go astray.
A variety of silencers for bow strings are available from Martin Archery, Cabala's Archery, and other sources. Available string savers are of several different types. One, due to its shape, is known as a “puff silencer.” Puff silencers are typically made of leather and yarn strands.
A second type of silencer is the “whisker silencer,” also named for its appearance. The whiskers of the silencer are commonly made from a rubber or comparably flexible material.
Other commercially available string silencers are made from fleece and such exotic materials as beaver hide.
The available devices, however, are not as effective as one might wish. Therefore, there is a continuing need for a better string saver.
SUMMARY OF THE INVENTION
There have now been invented and disclosed herein certain new and novel string silencers which are highly effective. Another advantage of the string silencers disclosed herein is that the reduction in initial arrow velocity, inevitably associated with the use of a string silencer, is very small.
One type of string silencer embodying the principles of the present invention and having the just-discussed advantages is a strip-like device fabricated from vibration damping material. These string silencers are knotted onto the bow string, one at each end of the string.
A second type of string silencer also embodying the principles of the present invention, is likewise fabricated from a vibration damping material. This string silencer is installed between the two parts of a split bow string and retained in place by complementary, integrated, silencer bosses. Split bow strings are commercially available, and other bow strings can be split to accommodate the silencers with a conventional string splitter.
