A coin-operated pay telephone is made secure from the removal of the coin return mechanism by a vandalizing bar and the subsequent collection of returned coins by vandals. A security bar is inserted behind the coin chute and down through an opening in an intermediate strengthening plate to block rocking of the coin return mechanism by a vandalizing bar and its translation forward out of the casing through the opening in which a finger is normally inserted to retrieve coins for incompleted telephone calls. The security bar includes a shoulder which rest on top of the rear edge of the coin return mechanism. The rear of the security bar includes a horizontal slot which is received on the portion of the strengthening plate behind its opening to prevent displacement of the security bar.
In a coin operated pay telephone, a telephone casing having at intermediate of its height a horizontal strengthening plate that has a rear opening and having a rectangular front opening below said plate, a coin return mechanism having a tube rectangular in cross section extending forwardly out of said rectangular front opening where the mechanism terminates in a lateral flange about the casing and having an upper rear portion formed with a coin receiving opening below said rear opening, a coin chute communicating with said coin receiving opening in said coin return mechanism and extending through said rear opening, and a reinforcing bar also extending through said rear opening and having a shoulder engaging the upper side of the upper rear portion of the coin return mechanism to prevent its being rocked clockwise about the line of engagement of its tube behind its lateral flange with the casing below said rectangular front opening.
