  • Patent number: 5036828
    Abstract: A magazine for targets to be thrown from a throwing device having a rotatable throwing arm mounted for rotation with a shaft is disclosed. The magazine comprises a stationary plate having a transfer opening therein and a holding member for holding a plurality of columns of targets. The columns are supported by this stationary plate except at the transfer opening. An indexing mechanism selectively rotates the holding member about the shaft in synchronism with the throwing arm so that when one of the columns passes over the transfer opening, the lowermost target in the column passes through the opening and onto the throwing arm. The indexing mechanism is arranged to arrest movement of the holding member relative to the shaft in a position where the targets cannot pass through the opening. A restraining mechanism prevents all but the lowermost target in each column from passing through the transfer opening, as the columns pass above the transfer opening.
