-of the improved devices.
Various modi?cations and changes in structural details
of the device may be resorted to, within the scope of
the appended claims, without departing from .the spirit
60 of the invention.
What is claimed is:
1. A pin wheel comprising the combination of a flat
disk having a central opening to receive a supporting
pin about which the disk rotates, a pair of pots, each
in the form of a tube of substantial length, lying against
one face of the disk on opposite si-des of and equidistantly
spaced from said opening, each pot being secured to said
face of the disk along the surface of the pot which is
in contact with the disk and the pots being substantíally
parallel with one another and having their transverlse
centers located on a line extending diametrically of the
disk and substantially perpendicular to the pots, each pot
having a nose end and a tail end, the pots being posi
tioned for discharge in opposite directions from their tail
ends and along paths substantially parallel to the said
face of the disk, a combustible blast generating materialV
Within the pots releasable through the tail ends of the
pots upon ígnition, a starting fuse in and projecting from
the tail end of one pot, :and a connectíng fuse leading 1
from one of vthe ends of said one pot to the tail end of the
other pot.
2. The invention according to claim 1, wherein the
said one of the ends of said one pot is the tail end.
3. The invention according to claim l, Wherein the
said one of the ends of said one pot is the nose end.
