Abstract: A flexible force transmitting link assembly includes flexible links that extend between the bow limbs and are connectable to a bow string and bow limbs. Connecting link members extend rearwardly and connect a flexible link to a bow string. An arrow, when positioned for firing, engages one of the flexible links.

Abstract: A pulley adapted to be mounted at each end of a bow and so constructed as to permit adjustments in the eccentric axis of rotation relative to a bow. Each pulley at the end of a bow includes a pair of annular grooves positioned in spaced relation around the periphery of the pulley. A first and second set of slots extend radially through the rim portion of each pulley and into the first and second annular grooves respectively. The sets of slots are diametrically opposed on the rim. The cable is reeved about each pulley and positioned in a selected pair of slots so that a preselected amount of cable is positioned on the pulleys corresponding to a preselected draw length and/or draw weight of the bow.

Abstract: The archery bow has a frame, a pair of bow arms with tip ends extending oppositely from the frame, a bowstring extending between the bow arms, and a link with opposite ends. At least one of the bow arms is flexible and provides a tension force for the bow. One end of the link is engaged to one of the bow arms and the opposite end is connected to the bow. During an initial rearward drawing movement of the bowstring the tension force on the bowstring increases and the tension force on the link decreases. One embodiment of the disclosure presents a bow wherein one end of the link is connected to one of the bow arms and the other end is connected to the bow and the bow arms flex unequally during drawing movements of the bowstring. Another embodiment of the disclosure presents a bow in which both bow arms are flexible and the link engages both of the bow arms.

Abstract: A draw stop mechanism for a compound archery bow. The draw stop mechanism includes first and second draw stop members with each stop member being fixedly secured to one pass of the bow string and slidingly receiving an adjacent pass. In operation, for example, with a compound bow having at least three passes of the bow string through its pulley system between the ends of the bow, the first and second draw stop members are respectively secured to two of the three passes. Then, as the third pass is drawn back causing the bow string to move through the pulley system, the first and second passes move by each other in opposite directions until the first and second stop members abut one another. When they abut, the bow string has been drawn to the desired length. If a longer or shorter draw length is desired, one or both of the stop members can be selectively moved to other secured positions along the respective passes.

Abstract: Cable ends of a compound bow are adjustably and securely anchored by an attachment member pivotally mounted adjacent the bow eccentric wheels. The attachment member body is of substantially constant thickness and includes a plurality of openings therethrough parallel to the opposite planar faces of the body and angularly offset relative to one another to define a circuitous cable pathway. An end section of the cable is secured by insertion of a threaded lock device through an edge wall of the body into an enlarged transverse anchor bore allowing radial distortion of crimping of the cable end section.

Abstract: A compound bow includes improved cam members eccentrically mounted upon the bow limb tips and including a bowstring segment adjacent a tension cable segment. The bowstring segment is provided with a main body section having a curved lever section extending outwardly therefrom. A groove or track is formed in the periphery of the curved lever section while a parallel groove or track is provided in the outer periphery of the tension cable segment. A bowstring end is disposed within each lever section track while each tension cable segment track receives the cam end of a tension cable. Adjustable or replaceable elements allow for the ready synchronization of the two cam members as well as variation of the bow draw weight. The two cam segments may be constructed either as a unitary member or as separate, angularly adjustable components.

Abstract: A limb for a compound archery bow has an inboard end and an outboard end at opposite sides of an elongate axis. The inboard end is adapted to be secured to a handle riser of the bow. The outboard end is forked to define an outward opening crotch for accomodating a pulley. The limb is split along its elongate axis from the inboard end of the crotch for a substantial portion of the length of the limb toward the mounting at the limb inboard end to divide the limb into two limb portions on opposite sides of the elongate axis. Cooperation is provided at at least one location along the limb for holding together the limb portions sufficiently so that, upon application of a limb flexing force to a pulley axle at the outboard limb end, the limb portions flex essentially as though the limb were unsplit along its length.

Abstract: An archer's compound shooting bow has rigging cables and pulleys arranged to eliminate torque on the limbs when the bow is fully drawn and to permit an arrow to fly true past the rigging when the bow approaches its rest condition. Each pulley has two grooves receiving an adjacent rigging cable. The grooves have variable separation at different locations along the pulley rim. Each pulley is mounted on a limb alongside the opposite rigging cable dead end. As to each limb, the connection of the opposite cable dead end and the location of the adjacent cable tensions are arranged, in respect to their magnitudes at full draw, to apply no net torsional moment to the limb about its torsional axis.The separation between the pulley grooves corresponding to the rest condition permits arrow feathers to pass the rigging cables without contact, which is not true at full draw. The groove for the shooting string is normal to the pulley rotational axis. The other groove is substantially helical to the first groove.

Abstract: A pair of limbs extending from opposite end portions of a handle member. Each limb has a free end portion upon which is rotatably and eccentrically mounted a pulley. A continuous cable is reeved about the pulleys and includes an arrow string portion extending between the limbs for receiving the arrow. The cable portions extend from the pulleys and through a cavity in the handle member where they are supported by idler pulleys. The pulleys are eccentrically mounted by devices that permit adjustments in the eccentric axis of rotation of each pulley relative to a limb to effect a change in the draw weight and draw length of the bow. Each pulley includes a pair of annular grooves positioned in spaced relation around the periphery of the pulley. A first and second set of slots extend radially through the rim portion of each pulley and into the first and second annular grooves respectively. The sets of slots are diametrically opposed on the rim.

Abstract: Cable ends of a compound bow are adjustably anchored by an attachment member pivotally mounted adjacent the bow eccentric wheels. The attachment member includes a plurality of openings therethrough which are angularly offset relative to one another to define alternate circuitous cable pathways. A releasable lock device engages the cable end in one of the attachment member openings while a laterally offset section on the attachment member allows alternative 180.degree. reversible mounting thereof.

Abstract: An archery bow having a handle, an inner pair of bow limbs projecting outwardly from opposite ends of the handle and an outer pair of bow limbs projecting outwardly from opposite ends of the handle. A cable is connected to ends of the inner bow limbs and through the handle via a pulley system. A cocking mechanism is attached to an end of the cable and is mounted at an end of one of the inner bow limbs for enabling the archer to increase tension on the cable whereby the inner bow limbs are stressed and placed in a cocked position. A release mechanism is mounted at an end of one of the outer bow limbs. When the archer draws and releases the bow string extending between the outer limbs, the release mechanism triggers the cocking mechanism to release the inner bow limbs which act in cooperation with the outer bow limbs whereby increased thrust is imparted to the arrow.

Abstract: A compound bow includes a pair of limbs each having a first end portion connected to a handle member and a second or free end portion. A bracket is connected to a free end portion of each limb of a compound bow. The bracket has a limb engaging portion positioned in abutting relation with the limb free end portion and a pair of plates extending outwardly therefrom. A pulley is positioned between the plates and is eccentrically and rotatably connected thereto. A continuous cable is reeved about the pulleys. Aligned bores extend through the bracket and limb free end portion. Fastening members extend through the aligned bores to secure the bracket to the limb. The bores through the limb have a diameter greater than the diameter of the fastening members. Thus the fastening members are secured to the bracket but are removed from contact with the limb.

Abstract: An archery bow having limbs of adjustable resilient force with the draw poundage force necessary to maintain the bowstring at full draw being substantially less than conventional compound bows and with the propelling force on the arrow increasing substantially uniformly from a minimum at full draw to a maximum at the point immediately preceding free arrow flight. The resilient limbs flex in a direction away from the archer and have pivotally mounted force multiplying mechanisms at their ends interconnected by non-yieldable cables to the bow handle.

Abstract: An archery bow and drawstring pulley assembly which is mounted at each end of an archery bow limb for receiving a drawstring. Each pulley assembly includes a first U-shaped housing which is connected to a bow limb, a second housing which is U-shaped and receivable between the U-shaped first housing walls. A pulley wheel is mounted on a pin disposed within the second housing. The first and second housings are hinged together, which allows the second pulley housing to be pivoted relative to the first housing. A rigid shaft is connected to the first and second housings which allows for threadably adjusting the position of the second housing with respect to the first housing. The pulley assembly allows for precise tensioning adjustment of the bow drawstring by movement of the positioning shaft to the exact desired position without experiencing any loss of bow string force.

Abstract: An archery bow having a pair of elastic limbs at least one of the limbs storing potential energy in the deformation of its cross sectional shape as the bow is drawn as well as in its bending mode in the plane of the bow.

Abstract: A training aid for archery, which permits relief of the bow tensioning force on the archer's shooting arm by transferring the force to the gripping action of both hands, embodying a spanning member having means at each end adapted to be gripped by the hands of the archer one in conjunction with the bow and the other in conjunction with the string and the end of the arrow, which spanning member is appropriately formed to avoid interference with the action of the string. An attachment is also provided for tying the spanning member to the drawing arm of the archer to maintain the arm in proper alignment with the arrow during aiming and which attachment is pivoted with respect to the spanning member to facilitate the withdrawing of the next arrow from the quiver after each firing.

Abstract: A bow having a variable tension bowstring including one or more movable connecting points for the bowstring which points travel along the bow limbs from more central positions toward the limb tips as the bowstring is drawn, whereby the "drawing force," required to draw the bowstring to a fully extended position, gradually increases to a peak and then decreases and stabilizes so that the drawing force required to maintain the bowstring fully drawn is much less than the force at its peak. A pair of rollers are coupled to the bowstring and mounted for movement along the bow limbs. The rollers are connected by a member for keeping the distance between the rollers constant while the rollers ride along the limbs as a bowstring is drawn.

Abstract: A pair of oppositely extending bow arms on a main body portion have guides on their tips. A bowstring extending between the tips has end sections movably contacting the guides. The bow has a drawing force produced either by flexible bow arms or a resilient member on the bow, and a second guide is employed to receive the end sections of the bowstring and position them so that they will be acted upon equally by the drawing force while moving in unison with it to provide a balanced bow for accurate shooting of arrows. Control apparatus may be employed to decrease the tension on the bowstring as the latter approaches its fully drawn condition. In bows using flexible bow arms as the drawing force, a cable operatively connects the arms and unites them into common operation.

Abstract: An archery bow with an improved construction for reducing the holding force at the end of the draw, the bow having a non-flexing handle portion and flexing limbs extending therefrom with pulley means eccentrically mounted at each end of the handle portion with concentric pulleys at the ends of the flexing limbs and a bowstring passing over each said eccentric pulley and said concentric pulleys to assure equality of motion of said eccentric pulleys as the arrow is drawn to a release position.

Abstract: An archery bow having a riser that is adapted to be grasped by an archer and which has a face and upper and lower, opposite end portions. The inboard ends of a pair of elongate spring members are mounted in cantilevered fashion from the face of the riser, one in association with each opposite end portion thereof. The medial portion of a limb member, in the fashion of a second degree lever, is pivotally mounted on the outboard end of each elongate spring member. A bow string extends between the outboard ends of the two limb members, and a cam follower is presented from the inboard end of each limb member to engage a corresponding cam secured to the face of the riser and which serves as a fulcrum against which the limb member acts to cock the spring member in response to the application of a drawing force to the bow string. The configuration of the cam determines the functional interrelation of the draw weight in response to the draw displacement of the bow string.
