This invention relates to the release of bombs
from aircraft, and without intending to restrict
the manner of its use, it is particularly designed
to insure, by electrically energized but positively
electrical skip-station devices have not, in prac
tice (nor have mechanical devices heretofore
known), proven wholly satisfactory; at times
such devices may fail to skip an empty station,
operable mechanical means, the successive release of bombs supported on vertical racks,
Whether or not such bombs are supported from
successive stations on such rack, or on companion racks, or at will to insure substantially simultaneous manual and mechanical release, that
is, salvo release, of all such
It is an object of the present invention to provide such bomb releasing means which will safely
and positively select and condition the proper
bomb station to be released, the next in the intended order of release, and which will operate
to prevent the release of any other bomb or
bombs, except in the event it is desired to salvo
and drop all bombs, as might be required in the
event a bombing airplane is about to make a
5 or may run through a given station and the next
station, to release not one but two bombs-in
forced landing without having discharged its
bombs.
It is a further object to provide such a device
which is adaptable to the successive release of
bombs of varying sizes from any given rack, or
from alternate racks, so that if the size of the
bombs, or the relative size of different bombs, is
such that certain stations of the rack are unoccupied and not cooked the device will automatically and by mechanical means select and con-
dition each cocked station in succession, skipping
the uncooked stations, to the end that the bomb-
other words, they have not heretofore been found
wholly dependable. Nevertheless, it is very de
sirable to enable release of the bombs selectively
10 by mere pressure upon an electric ?ring button,
and to utilize the same electric impulse further
to initiate advance of mechanical means to con
dition the next loaded station for release upon
the next pressure upon the ?ring button, whether

just released 01' is spaced therefrom by one or
more empty stations. The present device, in
practice, has been found satisfactory and re
liable.

A further object of this invention therefore,
is to provide mechanical means such that the se
lector bar shall pass through all empty bomb rack
stations, and stop at the station of the next bomb
on the rack or companion rack to be released,
25 thus making the selection of loaded and cooked
stations automatic.
It is a further object to provide safety means
which will prevent any movement of parts fol
lowing release of a bomb until the actuating or
30 tripping means has been returned to its initial
position, thus preventing interference of parts
and preventing accidental slippage which might
or need only press an electrical actuating butstrip all bombs from the rack when it was in

Thus the bomb rack stations may "be 40 ping of a bomb during the operation of securing
loaded in any sequence desired or rendered nec-

and still the bomber may drop the next bomb in
another bomb in‘place.
It is a further object to provide in such a bomb

device in cocked position and capable of being
tripped to effect release of the bomb, and three
devices controlling the operation of the holding
device, these three devices being common to and
preferably extending through all stations, the
whole cooperating mechanically.
These three devices may be designated, one, a

described its right hand end is in the path of a

engage and depress the now projecting end of the
pin 43, thus‘ releasing the latch 95 from the arm
of an armed station, and consequently all parts
are locked and held safely against release of any
bomb. This position of the parts is illustrated
in Figure '10. If, however, the salvo bar 2 is
9:3 and permitting the link 9 to move to the right,
as seen in Figure 2, releasing the bomb associated
with this link. The lowermost bomb in Figure
2 has been shown thus released, and the inter
mediate station is now conditioned and ready
for release of its bomb, while the uppermost sta
tion is not yet conditioned.
This selection of the stations is accomplished
by the station selector bar 3, which carries the
sears 34. This bar is also provided with a plu
rality of similar sears 3!, 32 and'33, one for each
station. The end of each of these sears is po
moved to an intermediate position, as shown in
Figures 3, 4 and 5, parts are unlocked and ready
for release of a bomb.
i
If it is desired to drop all bombs simultaneously
the salvo vbar is moved upward, and a cam sur
face 23, ‘leading to a notch 24, depresses the
head M in the same manner that it is depressed
‘by engagement of the sear Hi with the pin 4,
except that the'engagement is now between the
cam 23 and the head 4|, and by proper spacing
of the cams 23 relative to all stations this de
presses and trips all the stations substantially
simultaneously, and all bombs are consequently
sitioned to engage the shoulder 91 on the 'arm- 94
of its particular station, and by thus engaging
the shoulder s‘l movement of the station selector
bar 3, in response to its spring 39, is stopped, and
released at once. This position of parts is shown
the station selector sear 3% is brought into posi
in Figure 11. Preferably the several cams 23 are
tion to move the pin it of this particular station 20 so spaced that lower stations are released slightly
into the path of the solenoid sear M. This con
dition is illustrated in Figures 3, 6 and 7. After
tripping or rel-ease of this station, illustrated in
Figure ll, the arm 94 files away from the latch 95,
under the influence of spring 92, whereupon the
station selector bar 3 is free to move, under the
‘in?uence of the tension spring 39, and the sear,
3i for example, moves under the cut-away por
tion ‘98, previously referred to, as illustrated in
Figure 5, and now this station cannot be recocked C15 C)
until the station selector bar 3 has been moved
back to its initial position. However, the next
sear, 32 for example, has come into engagement
with the shoulder 9'! of the next station above,
provided that station was cooked. If it was not 3.3
cocked, the sear 32 passes by this station, and
the station selector bar 3 does not stop until the
next sear
has come into engagement with the
shoulder 97 of the next station in the‘rack, which
we can assume is cocked.
Thus the station se
lector bar automatically passes through any un
cocked station, and conditions the next cocked
station.
In order to prevent movement of the station
selector bar until the solenoid bar, under the in
?uence of tension spring 39, has been returned to
its initial position, under the in?uence of its ten
sion spring l9, we provide a temporary locking
device, such as that illustrated in Figures 8 and
9. An arm ‘i, pivoted at ‘in, extends transversely
between the solenoid bar I and the station se
lector bar 3. The solenoid bar 5 has a cam slot
ll’, within which is engaged one end of the arm
‘I, and the station selector bar 3 has a series of
spaced notches 3'! for engagement by the oppo
site and of the arm ‘I.
This end of the arm ‘I
is guided between ?xed guides ‘H 50 that it may
not be moved under the influence of the spring
39 acting on the station selector bar. With move
ment or" the solenoid bar upward, that is, in the
direction to release a bomb, one end of the arm
7 is moved upward into a notch 51, thus locking
the station selector bar in its position until the
solenoid bar has been moved downward again,
upon deenergization of its solenoid, whereupon
the station selector bar 3 is unlocked and moves
to its new position, as in Figure 5, to condition
the next cocked station.
The salvo bar 2 is‘provided with a slot 2d which
embraces the head 4! carrying the slide pin ii.
This slot is provided with a cam surface 2! lead
ing to a notch 22, which when it engages the head
in advance of the next station above, so that a
stripping action, or successive release, occurs.
The mechanism for operating the salvo bar is
preferably wholly manual, and is shown as a bell
crank lever 25 operable by a link 26 extending
to the bomber’s station.
It is frequently desirable to connect two such
racks for alternate operation, for the stations
may be so- spaced as to receive the smallest size
of bomb, and when larger bombs are employed
it may be necessary to use alternate stations, and
to stagger the relationship of the occupied and
cocked stations in the two connected racks, so
that a' bomb may be released ?rst from one rack,
then the‘next bomb from another rack, then a
bomb-from the ?rst rack, and so on. In order
to connect the racks for such operation we may
provide rack teeth I39 on each station selector
bar -3, engageable by a pinion 33 on a shaft 35,
. whereby movement of one station selector bar
is communicated to the companion station selec
tor bar in the other rack, and the stoppage of
either one effects stoppage of the other. Simi
larly rack teeth HS are provided on each of the
solenoid bars I, with which is engageable a pin
ion !8 on a shaft IE, this shaft extending to the
companion pinion and solenoid bar in the com
panion release mechanism. On this shaft I6 may
be secured an arm 55 suitably connected to the
solenoid l3, whereby energization of the solenoid
will rotate the shaft I6 to effect release of a
bomb. All the salvo bars may be connected by
means such as the link 26 to a common point
where all can be operated manually together.
For a condition where two or more racks are to
be operated in succession (as distinguished from
alternately) by a common push button P, we pro
vide a cut-over switch 5, the handle 5i of which
projects in the path of an abutment 35 on the
station selector bar 3. When the station se
lector bar has released the last station in its
rack the abutment 35 strikes the arm 5i, throw
ing the switch 5 to an opposite position, and as
may be seen in Figure 12, when this occurs the
- particular solenoid controlling this release mech
anism is thrown out of the circuit, and the next
solenoid for the next release mechanism in order
is thrown into the circuit, so that by repeated
pressure upon the push button P in the hands
of the bomber all stations of the ?rst rack are
released in succession, and then all stations of
the next and succeeding racks are released in

station selector bar 3 is prevented from moving

can be discharged by accidental pressure of the
