  • Patent number: 4041927
    Abstract: An archery bow which uses a single adjustable load spring instead of the usual pair of flexible bow limbs as the resilient energy medium. Bow limbs which are relatively rigid are pivoted on the handle section and are coupled together and synchronized in travel rate and equalized in forces by a single synchronizing linkage. A single adjustable ratio changing mechanism is used to provide a high mid draw force and a low full draw force and include structure to change the draw distance at which these draw forces occur.These three features: a single adjustable spring, a single synchronizing mechanism and a single adjustable ratio changing mechanism make the bow highly efficient, easy to hold at full draw and readily adjustable for short or tall, weak or strong archers.

  • Patent number: 4004567
    Abstract: A compact pneumatically powered apparatus for automatically propelling game balls, especially tennis balls and the like intended to be stroked by a hand held racket or other implement, for training players in the proper return of the simulated ball action. Each ball is ejected from the apparatus with a combination of forward or straight-line acceleration together with a predetermined amount of ball spin to closely approximate the intentional spin placed on tennis balls when stroked obliquely by a tennis racket. This is achieved in the apparatus by a mechanism for flexing an elongate pliable member, such as a flexible belt, between an initial slackened looped condition and a straightened tensioned condition. The tennis balls are successively fed into a launching position contacting a surface portion of the slackened, looped belt that faces generally forwardly toward the direction of ball propulsion and is initially rearwardly of the final orientation of the tensioned belt.

  • Patent number: 3989026
    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.

  • Patent number: 3985358
    Abstract: A simulated baseball game can be constructed so as to utilize a simulated baseball tethered on an arm in such a manner that the ball can be rotated across a simulated baseball playing field. The arm is mounted on a pylon by a universal joint so that it can be rotated generally between the field area of the playing field and the home plate of the playing field. A spring-loaded, latch-controlled propulsion member mounted generally in the field area of the playing field is used to hit the ball so as to cause it to rotate from an at rest position in the field area of the playing field toward and across the home plate of the playing field. A simulated bat may be actuated during such movement of the ball in an effort to hit the ball toward any one of a plurality of targets located in the field area. A base hit or a home run is indicated by the ball hitting a target labeled so as to correspond to such a hit or a home run.
