June 10, 1930. A. F.. TEITSCHEID FUSE FOR PBOJECTILES Filed Sept. 19. 1928 avwcnto v Alfred F. Teitscheid Patented June 10, 1930 PATENT OFFICE ALFRED I. TEITSCHEID,' OF WI-IARTON, NEW JERSEY FUSE FOR IPROJ'EOTILES Application filed September 19, 1928. Serial No. 306,984.
(GRANTED UNDER THE ACT OF MARCH 3, 1883, AS AMENDED APRIL 30, 1928; 370 0. G. 757) a The invention described herein, if patented, may be manufactured and used by or for the Governmentv or governmental purposes, Without the payment to meof any royalty thereon.
The subject ofthis invention is a fuse for projectiles. V
The invention is characterized principally by a novel form of firing mechanism having a bore safety device which isolates the booster charge until the fuse is fully armed during flight.
. With the foregoingand other objects in View, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
A practical embodiment of the invention is illustrated in the accompanying drawings wherein:
' Fig. l is a longitudinal sectional view of the improved fuse shown in the unarmed position;
Fig. 2 is a similar view of the fuse in the armed position.
Referring to the drawings by numerals of reference: 7
In carrying out the invention there is provided a tubular fuse body 5 in which, are mounted a primer carrier 6 and a detonator carrier 7, the former being telescoped in the latter. The carriers are normally held together: against the action ofa separating spring 8 by means of a sleeve 9, one end of which is inturned as at 10 to engage in front 0 of an annular fiange'll on the primer carrier and the other end of which is releasably secured to the detonator carrier by means of centrifugally operable locking members which as shown are in the form of balls 12 disposed partly in a recess 13 in the carrier and artly in an aperture 14 in the sleeve. The halls areheld in this position by a cage 15 fixed in the fuse body 5 and forming a guide forthe detonator carrier.
The sleeve 9 is held in looking posit-ion against the action of a spring 16 by centrifugally releasable pins 17 mounted in the fuse'body and normally maintained in the path of movement of the sleeve. For convenience in assembly andalso for the purpose of permitting the spring 16 to-assist in moving the primer'carrier the inturned end 10 is confined between the flange 11 and a cap 18 threaded to the primer carrier and the'pins 17 directly engage the cap 18 in holding the sleeve, inthe locking position. The sleeve 9 is spacedfrom the fuse body adjacent the cage toenable the balls 12 to be thrown outwardly as shown in Fig. 2 after the sleeve has been moved forwardly under the action of its spring 16.
The-cap 18 is-apertured to receive a firing pin 19 movably mounted in the nose 20 of the fuse and the cap also serves to retain a guide sleeve 21 which holds the primer cup 22 in place. WVhen the primer carrier is in the unarmed position the firing pin can not reach'the primer.
The lower end of the detonator carrier 7 is formed with a cup 23 in which is placed the detonator 24. When the carrier is moved to armed position the cup is receivable in a recess 25 in the booster charge 26 and the flash from the detonator may pass through apertures 27 in the side walls of the cup. -When the carrier is in the unarmed position the detonator 24 is disposed in the cage 15 and the thick base or bottom 28 of the cup constituting a plug is positioned in the entrance to the booster charge completely isolating it.
The. primer and detonator carriers are locked when extended and in the armed position by means of a pair of centrifugally operable pins 29 mounted in the primer carrier and engageablein recess 30 in the detonator carrier when'the carrier has reached the limit of its arming movement and is seated on the booster casing 31. i
The arming of the fuse is accomplished when the pins 17 are withdrawn during flight'permitting the spring 16 to move the sleeve 9, primer carrier 6 and detonator carrier 7 forwardly until a stop member 32 on the sleeve is brought up against the fuse V a spring for actuating the sleeve, a centrifugally releasable lock for holding the sleeve against the action of its spring, a centrifugally releasable connection between the sleeve and the detonator carrier brought into position for release on movement of the sleeve, pins in the primer carrier engageable with the detonator carrier to hold'the carriers extended, a booster charge and a plug on the detonator carrier positioned in the entrance to the booster charge when the detonator carrier is locked to the sleeve.
2. In a fuse, a detonator carrier, a primer carrier telescoped in the detonator carrier, a spring normally tending to extend the carriers, a sleeve fixed to the primer carrier, a spring for actuating the sleeve, a centrifugal releasable lock for holding the sleeve against the action of its spring, a centrifugally releasable connection between the sleeve and the detonator carrier brought into position for release on movement of the sleeve, and pins in the primer carrier engageable with the detonator carrier to hold the carriers extended. 7
3. in a fuse, a detonator carrier, a primer carrier telescoped in the detonator carrier, a spring normally tending to extend the carriers, asleeve engaging the primer car ier, a spring for actuating the sleeve, a centrifugally releasable lock for holding the sleeve against the action of its spring, a-centritu gally releasable connection between the sleeve and the detonator carrier brought into position for release on movement of the sleeve and means for locking the carriers in extended position.
4:. In a fuse, a detonator carrier, a primer carrier telescoped in the detonator carrier, a spring normally tending to extend the carriers, a movably mounted sleeve able with the primer carrier, means releasable during flight for holding the sleeve against movement, a ball connection between the sleeve and detonator carrier, a cage for confining the ball connection and a spring for moving the sleeve and carriers to-position the ball connection free of the cage.
5. In a-fuse, a detonator carrier, a primer carrier telescoped in the detonator carrier, a. spring normally tending to extend the carriers a movabl mounted sleeve en a 'eable with the primer carrier, means releasa pair of telescopically mounted explosive train carriers positioned between the firing pin and booster charge, means for extending the carriers to move one towards the firing pin and one towards the booster charge, and
means for releasably holding the carriers in non-eXtended relation with their explosive trains in inoperative position with respect to the firing pin and booster charge.
