  • Patent number: 4198949
    Abstract: A slingshot for hunting, target shooting, or the like, and which includes an adjustably mounted aiming device optimumly located between the slingshot prongs for accurate and selective alignment of the projectile trajectory's range and horizontal placement. The elastic band is releasably mounted to the ends of the slingshot prongs, so that the band protrudes in alignment therewith, thereby reducing the danger of the projectile striking the slingshot or the user's hand, while permitting the mounting of the aiming device between the prongs and making possible rapid and convenient interchange of elastic bands. A slingshot handle, having a cross-sectional dimension parallel to the projectile's trajectory greater than the perpendicular dimension, is also provided for improved safety, accuracy, and facility of use.
