  • Patent number: 4738392
    Abstract: A mailbox provided with a first signal flag mounted for rotation between a first position indicating the presence of mail in the box to be picked up by the mail carrier and a second, neutral position is disclosed. A flange depending from the first signal flag is adapted to frictionally engage a portion of the mailbox door when the first signal flag is in the first position thereby retaining the first signal flag in the first position. When the mailbox door is opened, for example, by a mail carrier, the frictional engagement is broken and gravity causes the first signal flag to rotate to the second, neutral position. The mailbox is provided with a second signal flag mounted for rotation between a first position indicating that a mail carrier has opened the mailbox door to insert mail and a second, neutral position.

  • Patent number: 4721244
    Abstract: This invention relates to a device for signaling the delivery of mail, newspapers, or parcels in an enclosed receptacle that is open on at least one end, that end being the receiving opening for such deliveries, there being no closure for said opening. The principal application is for the commonly-used roadside newspaper delivery tube, the opening of which generally faces away from the residence so the presence of the newspaper is obscured from view by the resident for whom the newspaper is intended. The invention comprises a trigger element that blocks a portion of the delivery opening of the receptacle and a flag element that signals the delivery, these elements operatively slidably engaging one another.

  • Patent number: 4492335
    Abstract: A signaling device is shown for signaling the delivery by the mailman of mail into the mailbox. A flat signal member is provided having a large area visible from a considerable distance and from any angle of where the signal member is hanging below the box in signaling position. The signal member is mounted for pivotal movement on the mailbox between signaling and nonsignaling positions independently of opening and closing movement of the mailbox door. The mailman, if delivering mail, releases the signal member from a latched position on the door to drop to signaling position before opening the door to deliver mail. If not released, the signal member performs no signaling function and is not affected by opening and closing the door merely for mail pickup. Two forms of the signaling device are shown, one for original box manufacture and the other for attaching the signaling device to an existing mailbox.
