The means for positively holding the stirrup
I00 in its locked position varies somewhat from
that heretofore described in connection with the
toggle mechanism. A slide II 5, U-shaped in
cross section, is mounted on top of the side plates
I0 and is held in sliding engagement thereon by
hooks pivoted in said frame, a tie rod connecting
said hooks so that they will operate simultaneous
ly, a tooth on said tie rod, a tumbler pivoted in
two yoke-shaped, clamps M0, the ends of which
are suitably secured to the side plates. One end
of the slide H5 has a ?nger piece M1 by which
the slide may be manipulated to any one of three
positions as heretofore described in connection
With the operation of the trigger 57.
At the opposite end each leg of the slide H5 is
provided with a peculiar shaped slot H8. These
slots I I8 engage the turned down portions I05
on the stud I02. In the locked position the stud
I02 engages restricted portions N9 of the slots
and the stirrup I00 cannot be raised to allow
operation of the releasing mechanism. When
the slide i I5 is moved to its intermediate or ?ring
position the stud I02 enters widened portions I20
of the slots. The stirrup may then be raised by
the cam II 9 and the bomb discharged as hereto
fore described. A continued movement of the 70
slide to the emergency or salvo position causes
the stud I 02 to engage cam portions IZI in the
said frame and engaging said tooth so as to pre
vent movement of said tie rod and its hooks, a
lever pivoted in said frame, the free end of said
tumbler engaging said lever so as to prevent
movement of said tumbler, a toggle mechanism
mounted on said frame, the free end of said lever
engaging said toggle mechanism, means for
breaking the toggle so as to permit movement of
said lever, and means for holding said toggle in
a position slightly beyond dead center so as to
prevent movement of said toggle.

said hooks so that they will operate simultane
