Definitions
- the invention relates to a device for releasing shells and the like in aircrafts arranged to be manipulated from a'certain disv I tance by means of one or several strings or the like, for which application for Letters Patent was filed in Norway September 7, 1927, No. 38,343.
- the main object of the present invention is now to obtain a device of the said kind arranged thus that any number of the shells may be released simultaneously.
- Another object is to obtain a device of the said kind having only few moved parts and connections to the manipulating place.
- Fig. 1 is a side view of one form of the invention.
- Fig. 2 is a side View of a further modified form of the same. 7 r
- Fig. 3 is a side view of a further modified construction.
- the shell is carried in well known manner by a hook 8 which is locked in. its closed position by means of a trigger 7 of known construction kept in its locking position by means of a spring 12 but arranged to be pushed aside by means of a releasing hook 1 for releasing the shell.
- the hook 1 by means of which the shell is released is mounted on a slide 2 which may be moved in its length direction by means-,0 strings or the like, operated from the operating place.
- the releasing hook 1 is kept by 40 means of a spring 11 in its uppermost position in which the trigger '2' may be passed by the same without coming into contact with it.
- the trigger When the trigger is depressed it is according to Fig. '1 locked in such depressed position by means of a counterhook l. According to Figs.
- the device is locked in another'manner.
- the hook 1 takes up such a low position that it will strike the trigger 7 when the slide is movedtoward its outermost "position in releasing direction (to the left).
- the depression of the hook 1 is effected by means of a pawl 3 coacting with a recess, a
- a special releasing hook is arranged and at least one pawl.
- the pawls 3 are placed'in such a distance from therespective shell carrying hooks that the releasing hooks belonging to the several such-hooks will be gradually acted upon in the several positions of the slide 2. If the pawl 3 does not coact with the recess or the crosspin in the releasing hook it will when the slide is moved back (in the drawings to the left) pass the recess or the cross pin without depressing the same.
- Any number of releasing hooks may be gradually depressed and the corresponding shell carrying hooks be released when the slide 2 is fully returned to the releasing position.
- V In the drawings is shown an additional pawl 36 which will come to action simulta- 'neously'for all shells in a certain position of the'slide. 1 so Hereby is obtained a quicker adjustment for simultaneously releasing all shells. However the same adjustment may also be obtained by gradual adjustment of the releasing hooks for releasing the shells one by one.
- the shell carrying hook is secured by means of a safety plate 9 which is kept by a spring 14 in such a position that the hook is prevented from being opened.
- the safety plate may be turned away from this position by means of an impact 10 or the like onthe slide 2 striking against a wing on the safety plate so that the latter will be turnedaside and the securing action ceases.
- the hoop 16 on the shell itself will, when the shell is in position, raise an arm 17 so as to close a contact leading an electric current to a signal lamp on the operating place. The current is broken when the shell is released owing to the fact that the arm 17 by means of a spring 18 is depressed when the hoop is removed.

DEVICE FOR RELEASING SHELLS IN AIRCRAFT Filed Aug. 28. 1928 2 Sheets-Sheet 2 l at ented June 30, 1931 PER SLINDE, or KJELLER, NORWAY DEVICE FOR RELEASING SHELLS IN AIRCRAFT Appiieation filed August as, 1928, Serial No.
, The invention relates to a device for releasing shells and the like in aircrafts arranged to be manipulated from a'certain disv I tance by means of one or several strings or the like, for which application for Letters Patent was filed in Norway September 7, 1927, No. 38,343.
In previously known devices of this kind only one shell'may be released at a time or all i shells be released simultaneously.
' The main object of the present invention is now to obtain a device of the said kind arranged thus that any number of the shells may be released simultaneously.
Another object is to obtain a device of the said kind having only few moved parts and connections to the manipulating place.
The invention is illustrated in the accompanying drawings in which: 2o Fig. 1 is a side view of one form of the invention.
Fig. 2 is a side View of a further modified form of the same. 7 r
Fig. 3 is a side view of a further modified construction.
In all figures the same references designate simllar parts.
The shell is carried in well known manner by a hook 8 which is locked in. its closed position by means of a trigger 7 of known construction kept in its locking position by means of a spring 12 but arranged to be pushed aside by means of a releasing hook 1 for releasing the shell.
The hook 1 by means of which the shell is released is mounted on a slide 2 which may be moved in its length direction by means-,0 strings or the like, operated from the operating place. The releasing hook 1 is kept by 40 means of a spring 11 in its uppermost position in which the trigger '2' may be passed by the same without coming into contact with it. When the trigger is depressed it is according to Fig. '1 locked in such depressed position by means of a counterhook l. According to Figs.
, 2 and 3 the device is locked in another'manner. In this event the hook 1 takes up such a low position that it will strike the trigger 7 when the slide is movedtoward its outermost "position in releasing direction (to the left).
302,618; and in Norway September 7, 1927.
The depression of the hook 1 is effected by means of a pawl 3 coacting with a recess, a
crosspin or the like on thereleasing hook 1 in certain positions of the slide 2. When the slide is moved somewhat against the pawl 3 (in the drawings to the left) the latter will force the releasing hook 1 downwards in its releasing position and the releasing hook be secured in such a position. I 1
For each shell a special releasing hook is arranged and at least one pawl. The pawls 3 are placed'in such a distance from therespective shell carrying hooks that the releasing hooks belonging to the several such-hooks will be gradually acted upon in the several positions of the slide 2. If the pawl 3 does not coact with the recess or the crosspin in the releasing hook it will when the slide is moved back (in the drawings to the left) pass the recess or the cross pin without depressing the same.
Any number of releasing hooks may be gradually depressed and the corresponding shell carrying hooks be released when the slide 2 is fully returned to the releasing position. e
V In the drawings is shown an additional pawl 36 which will come to action simulta- 'neously'for all shells in a certain position of the'slide. 1 so Hereby is obtained a quicker adjustment for simultaneously releasing all shells. However the same adjustment may also be obtained by gradual adjustment of the releasing hooks for releasing the shells one by one.
When the slide 2 is moved to its outermost position opposite to the'releasing position the 'counterhook will be released by a stop 5 so that the counterhook will be released and the releasing hook 1 by means of a spring 11 be returned to its original position.
The shell carrying hook is secured by means of a safety plate 9 which is kept by a spring 14 in such a position that the hook is prevented from being opened. The safety plate may be turned away from this position by means of an impact 10 or the like onthe slide 2 striking against a wing on the safety plate so that the latter will be turnedaside and the securing action ceases. The hoop 16 on the shell itself will, when the shell is in position, raise an arm 17 so as to close a contact leading an electric current to a signal lamp on the operating place. The current is broken when the shell is released owing to the fact that the arm 17 by means of a spring 18 is depressed when the hoop is removed.
It will be understood that the invention is not limited to the shown forms but may as to details be varied in many ways without departing the scope of the invention.
