Abstract: A reusable paint dispersing grenade of the type employed in paint ball games is constructed in such a manner as to avoid the use of any combustible materials, and also to avoid the requirement for access to a source of compressed air for operation. The paint grenade of the invention has a hollow, fluid-tight casing defining an enclosed cavity that is divided internally into a marking paint chamber, a first propellant component chamber, and a second propellant component chamber. The propellant component chambers are each filled separately with propellant components, but remain isolated from each other until the paint dispersing grenade is used. At that time the propellant components chemically react with each other in a noncombustible manner to produce a quantity of gas under pressure.

Abstract: An automatic shooting target system is provided with an automatic target resetting arrangement that returns all of a plurality of laterally spaced targets to an upright disposition. Each of the targets is carried by a set of separate target mounting arms that are mounted for independent rotation about a target mounting shaft. The target resetting mechanism is formed by target resetting levers that are locked to the target mounting shaft for rotation therewith. A reset biasing mechanism, which may be a wound band spring that urges a ratchet wheel in rotation, is coupled to urge the target mounting shaft in rotation in a direction that resets the targets concurrently by means of the target resetting levers. However, a rotation inhibiting device, such as a sear, obstructs rotation of the ratchet wheel, and therefore rotation of the target mounting shaft, in the reset direction.
