Abstract
A sanitary refuse device for collecting waste products such, for example, as the droppings of dogs, cats, and other animals. A hollow, cane-like, substantially vertical handle has a pistol-type grip at its upper end and a pair of normally open, spring-biased, pick-up jaws at its lower end, one of the jaws being fixedly connected to the lower end of the handle and the other jaw being pivotally mounted so as to swing to and from the fixed jaw. A trigger in associated relation with the piston-type grip is connected to the pivoted jaw through the medium of an actuating rod which passes through the handle and normally exists under compression in order to maintain the pivoted jaw in its open position against the action of the associated spring. Retraction of the trigger places the actuating rod under tension so that it becomes a pull rod and causes the pivoted jaw to swing towards the fixed jaw into a closed position. A latch arrangement is associated with the trigger and maintains the latter in its retracted position until released.
