Claim 1
Independent Claim
105 words
An aerial bomb for breaking railroad rails comprising, in combination: an elongated casing having a longitudinal axis disposed generally horizontally in the operative position of the bomb; a flat vertical guiding vane attached to the rear of said casing; an explosive charge within said casing, said charge having Vgrooved portions facing outwardly to the sides of the casing and symmetrical with respect to the plane of said vane, said Vgrooved portions upon detonation of said charge serving to direct concentrated jets laterally outwardly of said casing; and an elongated detonator in said charge between said V-grooved portions and generally in the plane of said vane.
Claim 2
Dependent Claim
105 words
An aerial bomb for breaking railroad rails comprising, in combination: an elongated casing having a longitudinal axis disposed generally horizontally in the operative position of the bomb; a flat vertical guiding vane attached to the rear of said casing; an explosive charge within said casing, said charge having Vgrooved portions facing outwardly to the sides of the casing and symmetrical with respect to the plane of said vane, said Vgrooved portions upon detonation of said charge serving to direct concentrated jets laterally outwardly of said casing; and an elongated detonator in said charge between said V-grooved portions and generally in the plane of said vane.
Claim 3
Dependent Claim
79 words
The bomb of claim 1, wherein said charge comprises: a pair of V-shaped liners spaced apart with the apices thereof generally parallel to each other and vertical; a pair of generally parallel end plates having opposite side edges contiguous to the outer edges of said V-shaped liners, respectively, and defining therewith a double-wedge space; an explosive material filling said space; and said detonator disposed within said explosive material midway between said apices of the liners and generally parallel thereto.
Claim 4
Dependent Claim
93 words
The bomb of claim 1, wherein said charge occupies the lower portion of said casing and comprises: a liner formed with a pair of semiannular frustoconical surfaces joined together at the frustums thereof; a pair of parallel plates of half-circle form each closing off the base of one of said frustoconical surfaces, respectively, with the diametrical edges of the plates disposed in a plane; an explosive material filling the space defined by said liner and plates; and said detonator disposed generally perpendicular to said plates at the midpoints of the diametrical edges thereof.
