Abstract: A signalling device for attachment to a mailbox to visually indicate service to the mailbox. This signalling device is installed without any alterations to the mailbox by fastening its mounting plate to the top friction latch member with a pair of encircling straps. There is a transverse cylindrical body member at the front end of the mounting plate, with a pivot member extending through the body member. The pivot member is substantially parallel with the front of the mailbox and thus with the door. A signal flag member is pivoted on the pivot member such that it can be moved from a "tripped" position against the mounting plate to an upright "set" position. The signal flag member has a pair of leg members that substantially touch the mailbox door when the signal flag member is "set"; the door moving against these legs to trip the signal flag member when the door is opened. Various friction-engaging embodiments are disclosed to reduce the chance of false "trip" due to wind, rain, vibration, etc.

Abstract: A device is described which, when inserted under the rim of a toilet bowl in contact with the side wall thereof, uniformly distributes water over the surface of the bowl walls. This aids flushing material from the toilet. In many types of toilets, this also reduces the quantity of water required for each flushing operation. The device is flexible whereby installation and removal are facilitated in any shape of conventional toilet bowl.
