Abstract: A firearm for personal protection purposes is provided which is particularly useful in close combat situations. The firearm comprises a support which is in the form of a finger ring which has a barrel defining a chamber and has a trigger operated firing mechanism operable by the thumb of the same hand of a person as that on which it is worn. The trigger is rotatably mounted to the side of the ring and is spring loaded towards a cocked position.

Abstract: A riot control weapon comprises a barrel, a fixed breech block, and there-between a chamber having a loading aperture through which a cylindrical round of ammunition can be inserted and ejected, the round being insertable by firstly a translational movement to bring the forward end of the round into the chamber, and secondly a rotational movement during which the round is pivoted until the round is fully chambered in alignment with the barrel, and wherein the chamber is provided with an obturating surface which extends continuously from a point adjacent the forward end of the chamber adjacent the loading aperture, rearwardly and away from the loading aperture to complete a closed loop within a cylindrical surface internally of the chamber, whereby the said rotational movement brings the round into sealing contact with the obturating surface around a complete loop.

Abstract: A riot weapon comprises a barrel; a fixed breech block; and therebetween a chamber having a loading aperture through which a round of ammunition can be inserted so as to rest against the breech block, or ejected; a loading catch for retaining a round of ammunition in the chamber; a trigger; a firing pin which can be actuated to fire a round of ammunition by moving the trigger, the firing pin having a normal rest position in the breech block; means for preventing release of the loading catch except when the firing pin is in the rest position; means for releasing the loading catch automatically following actuation of the trigger; and means for exerting a force on the round of ammunition in a direction such as to effect ejection thereof through the loading aperture; whereby following firing of a round of ammunition and consequent release of the loading catch, the spent round is retained in place against the ejecting force solely by the frictional force between the spent round and the breech block, the frictional

Abstract: A double barrelled firearm includes first and second parallel barrels attached to a casing which includes a pair of spaced parallel arms. A firing lever is pivotable about a bearing extending between the spaced arms from a first non-firing position to second firing positions successively inwardly of the casing. A bolt is slidably mounted on the casing at a location rearwardly of the barrels. The bolt has first and second firing pins aligned with the first and second barrels. The first and second firing pins have extending therefrom respective first and second stops of different lengths. The first and second firing pins are urged toward the first and second barrels respectively. The firing lever has on a first end thereof a guard which, when the firing lever is in the first non-firing position thereof, acts on the first and second stops to maintain the first and second firing pins spaced from the first and second barrels, against the force of the urging means.
