Abstract
A pneumatic battering ram is disclosed. The battering ram has a housing, a pressurized air tank, a ramming head, and a pivotable ramming edge. Air released from the air tank into the housing forces the ramming head outward against an enclosure to forcibly open it. Where a slug is inserted into the housing, air released from the pressurized air tank into the housing causes the slug to hit the inner surface of the ramming head, forcing it outwardly against the enclosure.
Claims18
A battering ram comprising:
- a housing;
- a pressurized air tank coupled to one end of the housing;
- a ramming head slidably coupled to the other end of the housing;
- a ramming edge pivotably coupled to the ramming head;
- and
- a hinge mechanism connecting the ramming edge to the ramming head for allowing the ramming edge to remain flush against an enclosure when the housing is held at varying angles relative to the enclosure;
- wherein the hinge mechanism comprises:
- two spaced apart plates coupled to a distal end of the ramming head, each plate defining an aperture;
- a bolt passing through the aperture of each plate and through an aperture defined by a middle portion of the ramming edge;
- and
- a nut to secure the bolt in place.

A pneumatic battering ram comprising:
- a cylindrical housing;
- a pressurized air tank coupled to a proximal end of the housing;
- a cylindrical slug within the housing that slides along the length of the housing;
- a cylindrical ramming head slidably coupled to a distal end of the housing;
- a rectangular ramming edge pivotably bolted to a distal end of the ramming head, wherein a distal side of the ramming edge has a plurality of teeth for penetrating the enclosure;
- and
- a bolt assembly coupling a middle portion of the ramming edge perpendicularly to the ramming head, wherein the bolt assembly comprises:
- two spaced apart plates coupled to the distal end of the ramming head, each plate defining an aperture;
- a bolt passing through the aperture of each plate and through an aperture defined by the middle portion of the ramming edge;
- and
- a nut to secure the bolt in place.
8 more elements
A pneumatic battering ram comprising:
- a housing;
- a pressurized air tank coupled to one end of the housing;
- a ramming head slidably coupled to the other end of the housing;
- a ramming edge pivotably bolted to the ramming head;
- a slug within the housing that slides along the length of the housing;
- at least one aperture defined by the ramming head that aligns with at least one aperture defined by the housing for releasing excess air from the housing when air is released from the air tank and the slug slides toward the ramming head;
- and
- a bolt assembly for pivotably coupling a middle portion of the ramming edge perpendicularly in relation to the ramming head, wherein the bolt assembly allows the ramming edge to remain flush against an enclosure when the housing is held at varying angles relative to the enclosure, and wherein the bolt assembly comprises:
- two spaced apart plates coupled to a distal end of the ramming head, each plate defining an aperture;
- a bolt passing through the aperture of each plate and through an aperture defined by the middle portion of the ramming edge;
- and
- a nut to secure the bolt in place.
