Abstract: A coin retrieval device for a pay phone includes a panel having a shaft with a retrieval lever extending radially therefrom. A guide device is pivotably connected to the panel about two pins on two ends of the guide device. The guide device includes a guide plate and a jam plate pivotably connected to the end plate of the guide plate. A gap is defined between the guide plate and the jam plate for coins passing therethrough via a coin slot defined through the guide plate. One of the two pins has a torsion spring mounted thereto which has two ends respectively connected to the retrieval lever and the guide plate. The guide device can be pivoted relative to the panel by lifting the retrieval lever, and a distal end of the jam plate is pivoted toward the coin slot to prevent coins from being inserted into the coin slot.

Abstract: A coin escrow apparatus for use with pay telephones including side members at least partially defining a coin hopper, a door mounted between the side members for selective movement between an escrow position for supporting coins in the hopper, an acceptance position for releasing coins from the hopper in a first direction, and a return position for releasing coins from the hopper in a second direction. The door has an underside portion and one or more guides associated with the door for guiding the door for pivotal movement between the escrow, acceptance and return positions. A support member is pivotally positioned below the door and has an upper portion. The support member is capable of pivoting about a pivot axis below the door. One or more roller bearings is attached to the upper portion of the support member for engaging the underside of the door. An actuator for pivoting the support member is also provided.
