  • Patent number: 4301898
    Abstract: A specialized equipment carrying bag designed expressly for use by police officers is preferably made of light-weight nylon or other synthetic fabric carried by a pair of looped carrying straps one of which nestles a billy club just over the junctures of the strap ends with the bag. Velcro retainer straps further secure the billy club, there also being several external compartments at least one of which is sealed with Velcro strips to hold handcuffs in such a way that they are easily accessible with one hand. Other pockets are provided on the outside of the bag for flashlights, ticket books and other pieces of equipment and accessories needed by peace officers, and on one end wall of the bag a number of the shells are conveniently retained by means of an elastic strap stitched to the bag at spaced intervals to define elastic convolutions to individually secure shotgun shells.
