Abstract

A crossbow includes a body having a stock member and a barrel connected to the stock member. The barrel has an arrow receiving area for receiving an arrow. The crossbow also includes a bow having a pair of bow arms, a bowstring connected to the bow arms, a bowstring release mechanism used to hold and release the bowstring and, a scope mount used to hold a scope. An arrow retention spring is provided for retaining the arrow to the arrow receiving area. A vibration dampener may be positioned between the arrow retention spring and the scope mount in order to dampen the arrow retention spring vibrations made when shooting the crossbow. This greatly reduces unwanted noise.

Claims

1. A method of dampening vibrations in a crossbow caused by an arrow retention spring, comprising the steps of:

providing a crossbow comprising;

(a) a body comprising a stock member and a barrel operatively connected to the stock member, the barrel having an arrow receiving area;

(b) a bow operatively connected to the body and having a pair of bow arms;

(c) a bowstring operatively connected to the bow arms;

(d) a bowstring release mechanism operatively connected to the body for selectively holding and releasing the bowstring;

(e) a crossbow member; and

, (f) an arrow retention spring for retaining an arrow to the arrow receiving area, the arrow retention spring having a first end operatively connected to a crossbow device and a second end adapted to contact the associated arrow;

providing a vibration dampener for dampening vibrations caused by the arrow retention spring wherein the vibration dampener comprises two pair of opposing sides that may define contact surfaces for contacting the arrow retention spring and the crossbow member respectively, the first pair of opposing sides providing the vibration dampener with a first dampening characteristic and the second pair of opposing sides providing the vibration dampener with a second dampening characteristic;

positioning the vibration dampener between the arrow retention spring and the crossbow member; and

,

attaching the vibration dampener to the arrow retention spring.

3. A vibration dampener comprising:

a first, second, third, and fourth surface wherein the first, second, third, and fourth surfaces form a substantially wedge shape and the vibration dampener is formed of a highly pliable compound;

wherein the first and third surfaces are adapted to operatively contact a crossbow arrow retention spring and the second and fourth surfaces are adapted to operatively contact the crossbow member.

2. The method of claim 3, wherein the crossbow member comprises a scope mount having a channel, the step of, positioning the vibration dampener between the arrow retention spring and the crossbow member, further comprises the step of:

inserting at least a portion of the arrow retention spring and the vibration dampener into the channel.

4. The vibration dampener of claim 5, wherein the crossbow member comprises a crossbow scope mount having a channel and the second and fourth surfaces are adapted to be at least partially slideably inserted into the channel.
