## Abstract

A firing post is generally positioned at the center of the top end of the body of a toy projectile to receive a percussion cap cartridge. The toy projectile has a soft outer body made of light-weight, pliable, compressible material such as polystyrene. The firing post and cartridge are covered with a nose of compressible material which generally houses a hammer and firing pin in alignment with the firing post. A spring-loaded hammer and firing pin is cocked by sliding the hammer through a housing for the hammer until a notch in the stem of the hammer is engaged by the top of the hammer housing. The trigger is a lever which is movable against the inclined top end of the hammer stem. The hammer and trigger assembly may be rotated with respect to a firing chamber placed over a multiple-cartridge mount to successively fire caps on the mount. A spring-loaded index helps facilitate alignment of the trigger-hammer assembly and holes in the firing chamber.

## Claims

### Claim 1

A toy projectile comprising:
a body having an outer covering of light-weight, pliable compressible material; and
a firing post member for receiving a percussion cap cartridge affixed at an axial center of a front end of said body, adapted for detonating the percussion cap upon impact with a surface.

### Claim 2 (depends on 1)

The toy projectile of claim 1, wherein said firing post member is affixed at an axial center of said front end of said body.

### Claim 3

A toy projectile comprising:
a body having an outer covering of light-weight, pliable compressible material; and
a firing post member for receiving a percussion cap cartridge affixed at a front end of said body adapted for detonating the percussion cap upon impact with a surface.

### Claim 4

A toy projectile comprising:
a body of light-weight, pliable compressible material; and
a firing post member for receiving a percussion cap cartridge directly affixed to said body at an axial center of a front end of said body adapted for detonating the percussion cap upon impact with a surface.
