Force multiplying archery bow

Claim 1

An archery bow for propelling an arrow comprising a handle section having a pair of oppositely outwardly projecting limbs, each limb having a free end, and a drawstring having two ends adapted for propelling an arrow, which ends are respectively connected to the free ends of said limbs, the combination including: (a) a means for force multiplication mounted on the bow separate from said drawstring and connected between said resilient limbs for exerting flexing force on said limbs independently of the drawstring in response to drawing movement of the drawstring; (b) triggering means for releasing said flexing force from said limbs when flexed, whereby the fully reactive force of said flexed limbs is transferred from the force multiplying means directly to the drawstring; (c) a second string having two ends connected at each end at points of attachment to said limbs, said second string extending between said limbs, said second string having an effective length, each end of said second string respectively being connected to respective ones of said limbs at a location on said respective ones of said limbs between the location of attachment of said force multiplying means to said respective ones of said limbs and respective ones of said points of attachment of respective ones of said two ends of drawstring to said limbs; said means for force multiplication including a lever pivotally mounted to said handle section; said lever having a first moment arm and a second moment arm; said first moment arm being greater in length than said second moment arm; a means for connecting said drawstring to said first moment arm, such that drawing of said drawstring causes movement of said lever; a means for connecting said second moment arm to said second string, such that movement of said second moment arm causes a force to be exerted upon a portion of said second string; said effective string length being the linear distance between the points of attachment of said second string to said limbs; and (d) means for shortening the effective length of said second string between said points of attachment of said second string to said limbs, said means for shortening the effective length being connected to said second moment arm so as to be displaced thereby, said means for shortening being connected to said drawstring such that displacement of said drawstring in a predetermined direction causes displacement of said lever in a predetermined direction causing movement of said second moment arm in turn causing displacement of a predetermined portion of said second string so as to shorten the effective length of said second string which thereby creates inward tension of said limbs.
